Objective:Benign prostatic hyperplasia(BPH)is one of the most common diseases found among elderly men.Even though multiple risk factors of BPH have been identified in the past,the risk factors which have a direct impact on prostate volume have not been identified.In this study,we aim to determine the most significant contributing risk factors to prostate volume enlargement by analyzing possible associated risk factors previously studied.Methods:This is a quantitative study with an analytical observational design,performed using a retrospective cohort approach.Total sampling was performed on 83 patients who underwent transurethral resection of the prostate(TURP)in Sanglah General Hospital from January to February 2019.Bivariate analysis is performed to examine each variable's association with prostate volume followed by a multivariate analysis.All variables were reassessed with path analysis to measure the direct effects,indirect effects,and total effects on prostate volume.Results:Bivariate analysis shows that serum testosterone(R=0.208;p=0.059)and prostate-specific antigen(PSA)level(R=0.626;p=0.001)have a significant association with prostate volume.Multivariate analysis shows that serum PSA(B=1.4;p=0.001;95%confidence interval[95%CI]=1.039-1.770)and testosterone(B=0.024;p=0.005;95%CI=0.008-0.041)levels are significant among all the analyzed risk factors.There is a significant and strong effect of PSA to prostate volume(c=0.636;p=0.001)whereas testosterone has a significant albeit weak effect to prostate volume(c=0.246;p=0.009)based on the total effect of the path analysis.Conclusion:Serum testosterone and PSA levels are significantly associated with prostatic volume increase among BPH patients. 展开更多

The precise aetiology of benign prostatic hyperplasia (BPH) remains unclear; however, it is known that immunological inflammatory processes have a role in the pathogenesis of BPH initiation and progression. Nitric oxide synthase 2 (NOS2) inducible expression is closely correlated with prostatic disease, including prostate cancer and BPH. The aim of this study was to investigate the relationship between NOS2 polymorphisms and BPH. With a cohort of 205 controls and 229 BPH subjects, we genotyped three single nucleotide polymorphisms (SNPs) in the NOS2 gene, including rs2779248 (promoter, -278 T/C), rs 10459953 (5'-untranslated region) and rs2297518 (exon 16, missense, Ser608Leu), using direct sequencing and restriction fragment length polymorphism. The genotypic and allelic frequencies between control and BPH subjects were compared, and the associations among the BPH subjects were analyzed. SNPStats, SNPAnalyzer and HelixTree programmes were used to analyze SNPs. There was no association on SNPs between control and BPH subjects. When BPH subjects were analyzed, there was no association on SNPs between the low and high prostate-specific antigen groups. However, one SNP (rs 10459953, odds ratio [OR] = 0.44, 95% confidence interval [CI] = 0.29-0.65, P 〈 0.0001, in codominant model; OR = 0.23, 95% CI = 0.12-0.46, P 〈 0.0001, in dominant model; and OR = 0.46, 95% CI = 0.24-0.86, P = 0.015, in recessive model) was associated with prostatic volume in BPH. We detected a strong association in genotype frequencies of NOS2 SNP (rs10459953) between subjects with small and large prostatic volume in BPH. The result suggests that NOS2 may be associated with prostatic volume in BPH. 展开更多

Anthropometric measurements, e.g., body weight (BW), body mass index (BMI), as well as serum prostate-specific antigen (PSA) and percent-free PSA (%fPSA) have been shown to have positive correlations with total prostate volume (TPV). We developed an equation and nomogram for estimating TPV, incorporating these predictors in men with benign prostatic hyperplasia (BPH). A total of 1852 men, including 1113 at Tokyo Medical and Dental University (TMDU) Hospital as a training set and 739 at Cancer Institute Hospital (CIH) as a validation set, with PSA levels of up to 20 ng m1-1, who underwent extended prostate biopsy and were proved to have BPH, were enrolled in this study. We developed an equation for continuously coded TPV and a logistic regression-based nomogram for estimating a TPV grater than 40 mh Predictive accuracy and performance characteristics were assessed using an area under the receiver operating characteristics curve (AUC) and calibration plots. The final linear regression model indicated age, PSA, %fPSA and BW as independent predictors of continuously coded TPV. For predictions in the training set, the multiple correlation coefficient was increased from 0.38 for PSA alone to 0.60 in the final model. We developed a novel nomogram incorporating age, PSA, %fPSA and BW for estimating TPV greater than 40 mh External validation confirmed its predictive accuracy, with AUC value of 0.764. Calibration plots showed good agreement between predicted probability and observed proportion. In conclusion, TPV can be easily estimated using these four independent predictors. 展开更多

In benign prostatic hyperplasia (BPH), it provides important morphological information and assesses its impact, helping to guide the treatment. <strong>Objective:</strong> To compare intravesical prostatic protrusion (IPP) and middle lobe volume by ultrasound in BPH. <strong>Method:</strong> This was a single center prospective, descriptive and analytical study, over a period of 6 months, including 95 patients, undergoing prostatic trans-abdominal ultrasound. Patients were selected by a single urologist for clinical suspicion of benign prostatic hypertrophy. The ultrasound examination was done by a single senior radiologist. <strong>Results:</strong> The mean age of the patients was 66.63 ± 11.55 years with ranges from 38 to 98 years. The prevalence of BPH was 76.84%. The rate of patient with middle lobe protrusion was 48.42%. The mean middle lobe volume was 11.29 ± 12.90 ml. More than half of the patients (50.91%) had an IPP stage 3 of. The mean bladder wall thickness was 6.08 ± 2.58 mm, with 50.53% being pathological. The post-voiding residue (PVR) was significant in 38.75% of patients. Renal repercussions were present in 17.89%. The correlation analysis did not note a statistical link between prostate volume and quality of life score (<em>p</em> > 0.05). There was a statistically significant correlation between IPP values and quality of life score (<em>p</em> = 00461), IPSS score (<em>p</em> = 0.0424) and PVR (<em>p</em> = 0.0395). For middle lobe volume, there was a correlation with PVR (<em>p</em> = 0.0018). There was no correlation with clinical impact (quality of life score and IPSS score). <strong>Conclusion:</strong> The IPP appears to be an easy element to measure and better than the volume of the prostate and the middle lobe in assessing the impact of BPH. 展开更多

The occurrence of benign prostate hyperplasia(BPH)was related to disrupted sex steroid hormones,and metformin(Met)had a clinical response to sex steroid hormone-related gynaecological disease.However,whether Met exerts an antiproliferative effect on BPH via sex steroid hormones remains unclear.Here,our clinical study showed that along with prostatic epithelial cell(PEC)proliferation,sex steroid hormones were dysregulated in the serum and prostate of BPH patients.As the major contributor to dysregulated sex steroid hormones,elevated dihydrotestosterone(DHT)had a significant positive relationship with the clinical characteristics of BPH patients.Activation of adenosine 5'-monophosphate(AMP)-activated protein kinase(AMPK)by Met restored dysregulated sex steroid hormone homeostasis and exerted antiproliferative effects against DHT-induced proliferation by inhibiting the formation of androgen receptor(AR)-mediated Yes-associated protein(YAP1)-TEA domain transcription factor(TEAD4)heterodimers.Met’s anti-proliferative effects were blocked by AMPK inhibitor or YAP1 overexpression in DHT-cultured BPH-1 cells.Our findings indicated that Met would be a promising clinical therapeutic approach for BPH by inhibiting dysregulated steroid hormone-induced PEC proliferation. 展开更多

We evaluated the effect of isoquercetin(quercetin-O-3-glucoside-quercetin,IQ)as a functional component of Abeliophyllum disistichum Nakai ethanol extract(ADLE)on prostate cell proliferation and apoptosis and its effects on the IGF-1/PI3K/Akt/mTOR pathway in benign prostatic hyperplasia(BPH).Metabolites in ADLE were analyzed using UHPLC-qTOF-MS and HPLC.IQ was orally administered(1 or 10 mg/kg)to a testosterone propionate-induced BPH rat model,and its effects on the prostate weight were evaluated.The effect of IQ on androgen receptor(AR)signaling was analyzed in LNCaP cells.Whether IGF-1 and IQ affect the IGF-1/PI3K/Akt/mTOR pathway in BPH-1 cells was also examined.The metabolites in ADLE were identified and quantified,which confirmed that ADLE contained abundant IQ(20.88 mg/g).IQ significantly reduced the prostate size in a concentration-dependent manner in a BPH rat model,and significantly decreased the expression of AR signaling factors in the rat prostate tissue and LNCaP cells in a concentration-dependent manner.IQ also inhibited the PI3K/AKT/mTOR pathway activated by IGF-1 treatment in BPH-1 cells.In BPH-1 cells,IQ led to G0/G1 arrest and suppressed the expression of proliferation factors while inducing apoptosis.Thus,IQ shows potential for use as a pharmaceutical and nutraceutical for BPH. 展开更多

Objective: Erectile dysfunction (ED) is a condition of insufficient penile erection, consistently or recurrently, for sexual activity. Tumor necrosis factor-alpha (TNF-α) induces transforming growth factor-beta (TGF-β), which causes the transition of epithelial cells into mesenchymal cells that affect ED. This study aimed to evaluate the roles of TNF-α, TGF-β, degree of lower urinary tract symptoms, and prostatic volume for the presence of ED in benign prostatic hyperplasia (BPH) patients.Methods: Our study performed an analytic observational retrospective cohort study using secondary data from four hospitals in Bali, Indonesia, including medical records and other administrative data. The sample was BPH patients with several history qualifications.Results: Our sample was 83 respondents, ranging from 50 years to 80 years, 61 respondents with ED and 22 with non-ED. The International Prostate Symptom Score showed a significant result, which indicates that ED is more common in patients with higher International Prostate Symptom Score (p=0.002). Moreover, the TNF-α of ≥43.9 pg/mg and TGF-β of ≥175.8 pg/mL were significantly associated with the presence of ED in BPH patients (p<0.0001). Despite these results, prostate volume is not significant with ED (p=0.947).Conclusion: TNF-α, TGF-β, and lower urinary tract symptoms severity can predict the occurrence of ED in BPH, while prostatic volume was not significant. 展开更多

Objective:The aim of this research was to evaluate the efficiency of reciprocating morcellation for removing giant benign prostatic hyperplasia during holmium laser enucleation of the prostate,investigate whether performing morcellation as a two-stage procedure improves tissue retrieval efficiency,and seek to determine the optimal interval between the two surgeries.Methods:This study included nine cases of holmium laser enucleation of the prostate with an enucleated prostate weight exceeding 200 g,indicative of substantial prostate enlargement.Morcellation was performed on Day 0(n=4),Day 4(n=1),Day 6(n=1),and Day 7(n=3).The intervals were compared regarding the morcellation efficiency,beach ball presence,and pathology.Results:The mean estimated prostate volume was 383(range 330e528)mL;the median enucleation weight was 252(interquartile range[IQR]222,342)g;and the median enucleation time was 83(IQR 62,100)min.The mean morcellation efficiency was 1.44(SD 0.55)g/min on Day 0 and 13.69(SD 2.46)g/min on day 7.The morcellation efficiency was 4.15 g/min and 10.50 g/min on Day 4 and Day 6,respectively,with significantly higher in the two-stage group compared to one-stage group(11.0 g/min vs.1.5 g/min;p=0.014).Efficiency was strongly correlated with intervals(p<0.001);the incidences of beach balls were 100%(4/4)and 60%(3/5)in the immediate and two-stage surgery groups,respectively.Conclusion:The efficiency of two-stage morcellation with reciprocating morcellators was highly related to the postoperative interval,with the maximum efficiency reached on Day 7. 展开更多

BACKGROUND Prostatic artery embolization(PAE)is a promising but also technically demanding interventional radiologic treatment for symptomatic benign prostatic hyperplasia.Many technical challenges in PAE are associated with the complex anatomy of prostatic arteries(PAs)and with the systematic attempts to catheterize the PAs of both pelvic sides.Long procedure times and high radiation doses are often the result of these attempts and are considered significant disadvantages of PAE.The authors hypothesized that,in selected patients,these disadvantages could be mitigated by intentionally embolizing PAs of only one pelvic side.AIM To describe the authors’approach for intentionally unilateral PAE(IU-PAE)and its potential benefits.METHODS This was a single-center retrospective study of patients treated with IU-PAE during a period of 2 years.IU-PAE was applied in patients with opacification of more than half of the contralateral prostatic lobe after angiography of the ipsilateral PA(subgroup A),or with markedly asymmetric prostatic enlargement,with the dominant prostatic lobe occupying at least two thirds of the entire gland(subgroup B).All patients treated with IU-PAE also fulfilled at least one of the following criteria:Severe tortuosity or severe atheromatosis of the pelvic arteries,non-visualization,or visualization of a tiny(<1 mm)contralateral PA on preprocedural computed tomographic angiography.Intraprocedural contrast-enhanced ultrasonography(iCEUS)was applied to monitor prostatic infarction.IU-PAE patients were compared to a control group treated with bilateral PAE.RESULTS IU-PAE was performed in a total 13 patients(subgroup A,n=7;subgroup B,n=6).Dose-area product,fluoroscopy time and operation time in the IU-PAE group(9767.8μGy∙m^(2),30.3 minutes,64.0 minutes,respectively)were significantly shorter(45.4%,35.9%,45.8%respectively,P<0.01)compared to the control group.Clinical and imaging outcomes did not differ significantly between the IU-PAE group and the control group.In the 2 clinical failures of IU-PAE(both in subgroup A),the extent of prostatic infarction(demonstrated by iCEUS)was significantly smaller compared to the rest of the IU-PAE group.CONCLUSION In selected patients,IU-PAE is associated with comparable outcomes,but with lower radiation exposure and a shorter procedure compared to bilateral PAE.iCEUS could facilitate patient selection for IU-PAE. 展开更多

BACKGROUND Secondary rectal linitis plastica(RLP)from prostatic adenocarcinoma is a rare and poorly understood form of metastatic spread,characterized by a desmoplastic response and concentric rectal wall infiltration with mucosal preservation.This complicates endoscopic diagnosis and can mimic gastrointestinal malignancies.This case series underscores the critical role of magnetic resonance imaging(MRI)in identifying the distinct imaging features of RLP and highlights the importance of considering this condition in the differential diagnosis of patients with a history of prostate cancer.CASE SUMMARY Three patients with secondary RLP due to prostatic adenocarcinoma presented with varied clinical features.The first patient,a 76-year-old man with advanced prostate cancer,had rectal pain and incontinence.MRI showed diffuse prostatic invasion and significant rectal wall thickening with a characteristic"target sign"pattern.The second,a 57-year-old asymptomatic man with elevated prostatespecific antigen levels and a history of prostate cancer exhibited rectoprostatic angle involvement and rectal wall thickening on MRI,with positron emission tomography/computed tomography PSMA confirming the prostatic origin of the metastatic spread.The third patient,an 80-year-old post-radical prostatectomy,presented with refractory constipation.MRI revealed a neoplastic mass infiltrating the rectal wall.In all cases,MRI consistently showed stratified thickening,concentric signal changes,restricted diffusion,and contrast enhancement,which were essential for diagnosing secondary RLP.Biopsies confirmed the prostatic origin of the neoplastic involvement in the rectum.CONCLUSION Recognizing MRI findings of secondary RLP is essential for accurate diagnosis and management in prostate cancer patients. 展开更多

BACKGROUND Carbon ion radiotherapy(CIRT)is currently used to treat prostate cancer.Rectal bleeding is a major cause of toxicity even with CIRT.However,to date,a correlation between the dose and volume parameters of the 12 fractions of CIRT for prostate cancer and rectal bleeding has not been shown.Similarly,the clinical risk factors for rectal bleeding were absent after 12 fractions of CIRT.AIM To identify the risk factors for rectal bleeding in 12 fractions of CIRT for prostate cancer.METHODS Among 259 patients who received 51.6 Gy[relative biological effectiveness(RBE)],in 12 fractions of CIRT,15 had grade 1(5.8%)and nine had grade 2 rectal bleeding(3.5%).The dose-volume parameters included the volume(cc)of the rectum irradiated with at least x Gy(RBE)(Vx)and the minimum dose in the most irradiated x cc normal rectal volume(Dx).RESULTS The mean values of D6cc,D2cc,V10 Gy(RBE),V20 Gy(RBE),V30 Gy(RBE),and V40 Gy(RBE)were significantly higher in the patients with rectal bleeding than in those without.The cutoff values were D6cc=34.34 Gy(RBE),D2cc=46.46 Gy(RBE),V10 Gy(RBE)=9.85 cc,V20 Gy(RBE)=7.00 cc,V30 Gy(RBE)=6.91 cc,and V40 Gy(RBE)=4.26 cc.The D2cc,V10 Gy(RBE),and V20 Gy(RBE)cutoff values were significant predictors of grade 2 rectal bleeding.CONCLUSION The above dose-volume parameters may serve as guidelines for preventing rectal bleeding after 12 fractions of CIRT for prostate cancer. 展开更多

Goal: To determine the type of comorbidity and highlight the complications of adenomectomy and comorbidities. Material and Methods: This is a prospective, descriptive, cross-sectional study lasting six (6) months, from July 1, 2022 to December 31, 2022. Patients with BPH on comorbidity condition taken care of during the study period AND have agreed to participate in the study. Results: During our study, 49 cases of benign prostatic hypertrophy with comorbidities were collected, representing a frequency of 29%. The average age ranges for the patients were 43 - 70 years. The age group most affected was 70 to 79 years old (38.80%). Nocturnal urinary frequency was the main reason for consultation present in all our patients. The most frequent comorbidity was hypertension, i.e. 83.70%. The PSA rate between 4 and 10 was the most represented, i.e. 42.86%. The prostate volume was between 61 and 100 ml in 40.82% of patients. Histology showed that it was a benign adenomatous hypertrophy of the prostate in 85.70% and a prostatic adenomyoma in 14.29%. Trans-bladder adenomectomy alone was the most performed technique, i.e. 49%, followed by trans urethral resection of the prostate, i.e. 38.80%. Retention of urine after removal of the catheter was the most observed complication, i.e. 12.20%. Conclusion: Benign prostatic hypertrophy with comorbidities constitutes a frequent association. Because their presence can affect effectiveness and lead to complications. 展开更多

Background: Benign prostatic hyperplasia (BPH) is defined histologically as adenomyofromatous hyperplasia of the transitional zone of the prostate. It remains the most common benign tumour in men over the age of 50, and transurethral resection of the prostate (TURP) remains the surgical treatment of choice. Objectives: To determine the indications and present our results of transurethral resection of the prostate. Patients and Methods: After obtaining approval from the ethics committee of the private hospital and the university hospital of Bouaké (Côte d’Ivoire), we conducted a cross-sectional study of transurethral resection of the prostate (TURP) to treat benign prostatic hyperplasia (BPH) between January 2021 and April 2023. All patients and their families were informed beforehand and had signed an informed consent form. All patients with benign prostatic hyperplasia (BPH) with ultrasound weight of less than 80 grams were included. The following parameters were studied: age, reason for consultation, ultrasound prostate weight of benign prostatic hyperplasia, indication for TURP, duration of operation, blood loss, duration of post-PRT urinary drainage, length of hospital stay, morbidity and mortality, and outcome. Results: 39 patients with a mean age of 58.3 years (57-77 years) underwent transurethral resection of the prostate (TURP). TURP was indicated in 46.15% (n = 18) of cases of refractory acute urinary retention with failure of the urinary catheter removal test, 17.94% (n = 7) of cases of lower urinary tract disorders that were incapacitating despite treatment, 15.38% (n = 6) of cases of refractory or recurrent urinary tract infection, 10.25% (n = 4) of cases of failure of medical treatment and 10.25% (n = 4) of cases of iterative hematuria. The mean duration of TURP was 53.68 min (48-57), the mean weight of the resected prostate was 58.7 g (35 and 83 g), blood loss was minimal in 92.30% (n = 36), the mean duration of irrigation-washing was 2. 5 days (1-3 days), the mean time for urinary catheterisation was 2.45 days (3 and 4 days), 5.12% (n = 2) of patients presented complications such as hemorrhage compensated by a blood transfusion. One patient developed orchiepididymitis (2.56%). The average hospital stay was 3.75 days (3-5 days). Pathological examination was in favour of BPH in 92.3% (n = 36) and the coexistence of BPH and prostate adenocarcinoma in 7.69% (n = 3). The results of TURP were considered good in 94.87% (n = 37). Mortality was nil. Conclusion: In view of our results, TURP is a reliable, elegant minimally invasive technique with low morbidity and mortality. 展开更多

Its frequency is variable and it is considered a poor prognostic factor. In our context, when prostatic carcinoma is diagnosed, pathologists do not always report the presence of this anatomopathological entity. We therefore conducted a study to determine the epidemiological and anatomopathological profile of patients with this lesion in Dakar. Materials and Methods: This is a retrospective descriptive study covering a 1-year period from January to December 2022. It focused on cases of intraductal carcinoma diagnosed among prostatic carcinomas collected in the anatomopathology laboratories of Hôpital Général Idrissa Pouye (HOGIP) and Hôpital Militaire de Ouakam (HMO). It was based on archives of anatomopathological reports, blocks and slides. A total of 200 cases of prostatic carcinoma were collated and reviewed to identify those presenting with intraductal carcinoma according to the diagnostic criteria of Guo and Epstein. Results: 87 cases of intraductal carcinoma were found, representing 43.5% of prostatic carcinomas. The mean age was 71 years. Patients in their seventh decade were the most represented, i.e. 42.5%. The majority of samples examined were biopsies (72.4%). The mean PSA level was 965.91 ng/ml, with extremes ranging from 0.03 to 10,000 ng/ml. Histologically, 96.5% of cases (N = 84) were invasive prostatic carcinoma. Gleason score 8 (4 + 4) was the most common, accounting for 42.53% (N = 37). On average, the study found four (04) foci of intraductal carcinoma per specimen, with extremes ranging from 1 to 30. Dense cribriform architecture accounted for 78.16%, loose cribriform for 11.5%, solid for 8.04% and micropapillary for 2.3%. Six cases (6.9%) showed foci of comedonecrosis. The vast majority of radical prostatectomies (87.5%) were classified as pT3. Node invasion and perineural sheathing were observed in 12.5% and 52.32% of cases respectively. Conclusion: Intraductal carcinoma is a poor prognostic factor that must be systematically reported in the anatomopathological report. In Senegal, it is often associated with advanced stage, high-grade carcinoma and high PSA levels. 展开更多

Introduction: Prostate cancer is the second most common cancer in men. The diagnosis is most often based on the prostate biopsies’ analysis and on histological criteria recognizable on standard coloring. In some cases, the use of immunohistochemistry is important. Objectives: This paper aims to specify the p63 phenotypic profile of lesions diagnosed benign, with minimal suspect foci, difficult to interpret, HGPIN (high grade intraepithelial neoplasia) and LGPIN (low-grade prostatic intraepithelial neoplasia) and evaluate the manual technique of p63 immunohistochemistry. Patients and Method: This was a retrospective, descriptive study of prostate biopsies recorded in the PAC service of the HALD from January 1st, 2018 to December 31st, 2018. It was completed by a manual immunohistochemical study of the blocks enrolled from November 19th to December 4th, 2020 in the PAC department of the HPD. The studied parameters were: registry number, age, clinical stage, prostate volume, PSA level, microscopic appearance and p63 immunohistochemical profile. Results: Our study included 60 prostate biopsies. The ages of our patients varied from 45 to 77 years, with an average of 64.2 years and a standard deviation of 6.2. The majority of patients were at clinical stage cT2b (33%) with a prostate volume varying between 33.15 and 169.4 cc. The minimum value of PSA in our series is 5 ng/ml, the maximum being 100 ng/ml with an average level of 24.1 ng/ml and a standard deviation of 21.2. Our series included 50 adenomyomatous hyperplasias, 7 adenomyomatous hyperplasias associated with chronic prostatitis, 2 HGPIN and 1 LGPIN. After re-reading we found 5 discordant cases, which corresponded to minimal suspect foci (kappa = 0.5098). The p63 marking was informative in 53 cases, i.e. 88%, and non-informative in 7 cases, i.e. 12%. Among the uninformative markings, 2 were due to lack of tissue adhesion to the slides. Among the informative markings, 11 were negative. p63 immunohistochemistry was useful in all suspected foci and detected 6 other minimal foci of adenocarcinoma. Conclusion: The immunostaining with the anti-p63 antibody in the prostate cancer diagnosis is of considerable benefit. It made it possible to correct 11.3% of benign diagnosis in minimal malignant focus in our context. Despite the difficulties associated with the manual technique, it is possible to have an informative rate, similar to the automatic technique. 展开更多

Introduction: Prostate cancer is one of the most common cancers in men. In cases of suspected locally advanced disease or lymph node or bone metastases, thoraco-abdomino-pelvic CT is still useful for detecting visceral metastases. In the course of this extension work-up, other abnormalities may be discovered by chance, which had previously remained silent, and which could be diagnosed and managed in childhood, hence the interest of presenting a case of incidental finding of pyeloureteral junction syndrome during extension workup for prostatic adenocarcinoma at Yaounde Central Hospital. Observation: A 72-year-old patient presented to the department with acute urinary retention. The clinical examination, with an empty bladder, and in particular the digital rectal exam (DRE), was in favor of malignant prostatic hypertrophy. A workup was ordered, including a total PSA returned to 61.3 ng/ml (PSA performed one week after the episode of acute urinary retention) with cytobacteriological examination of sterile urine. Renal function was slightly impaired, with creatinemia at 14 ng/ml. Renal and vesico-prostatic ultrasound revealed a 57 g prostate with regular, clean contours and a polycystic right kidney. A prostate biopsy was indicated, which revealed a histopathological aspect in favor of a prostatic adenocarcinoma ISUP 1. An extension work-up including a thoraco-abdomino-pelvic CT scan revealed no signs of local or distant secondary localization, but a pyeloureteral junction syndrome with significant hydronephrosis, parenchymal destruction and compensatory hypertrophy of the contralateral kidney was found. Conclusion: The prostate cancer extension work-up revealed a pathology that can be diagnosed early. It is therefore important to reinforce prenatal and natal screening, which will enable malformative uropathies to be identified early and corrected in time to preserve patients’ renal function. Furthermore, we must be careful in the ultrasound diagnosis of pyeloureteral junction syndrome. 展开更多
