Hematuria after nocturnal exercise of a man: A case report

BACKGROUND A man experienced multiple episodes of macroscopic hematuria following nocturnal exercise.Urinary stones and tumors were considered the two most likely causes.The patient had two hobbies:Consuming health care products in large quantities and engaging in late-night running.CASE SUMMARY Health care products contain a large amount of calcium phosphate,and we hypothesize that this could induce the formation of small phosphate stones.After exercise,the urinary system is abraded,resulting in bleeding.The patient was advised to stop using the health care products.Consequently,the aforementioned symptoms disappeared immediately.However,the patient resumed the above two habits one year later;correspondingly,the macroscopic hematuria reap-peared.CONCLUSION This finding further confirmed the above inference and allowed for a new avenue to determine the cause of the patient’s hematuria.

Safety and efficacy of transcatheter arterial embolization in autosomal dominant polycystic kidney patients with gross hematuria: Six case reports

BACKGROUND To retrospectively report the safety and efficacy of renal transcatheter arterial embolization for treating autosomal dominant polycystic kidney disease(ADPKD)patients with gross hematuria.CASE SUMMARY The purpose of this study is to retrospectively report the safety and efficacy of renal transcatheter arterial embolization for treating ADPKD patients with gross hematuria.Materials and methods:During the period from January 2018 to December 2019,renal transcatheter arterial embolization was carried out on 6 patients with polycystic kidneys and gross hematuria.Renal arteriography was performed first,and then we determined the location of the hemorrhage and performed embolization under digital subtraction angiography monitoring.Improvements in routine blood test results,routine urine test results,urine color and postoperative reactions were observed and analyzed.Results:Renal transcatheter arterial embolization was successfully conducted in 6 patients.The indices of 5 patients and the color of gross hematuria improved after surgery compared with before surgery.No severe complication reactions occurred.CONCLUSION For autosomal dominant polycystic kidney syndrome patients with gross hematuria,transcatheter arterial embolization was safe and effective.

Role of multi- slice CT urography over ultrasonography in patients with hematuria

Objective:Understanding the role of Multi-slice CT Urography(MSCTU)over Ultrasonography(US)in patients presenting with hematuria.Materials and Methods:Retrospective study enrolled 131 patients presenting with hematuria[microscopic hematuria(n=60)]and macroscopic hematuria(n=71)]who have undergone both MSCTU and US of urinary tract system simultaneously.Results of tests were compared with respective surgical and histopathological analysis of lesion.The cases obtained were bladder carcinoma,ureter carcinoma,renal carcinoma,urinary tract calculi and bladder inflammation.PASW-18thstatistical tool was used for obtaining statistical analysis and final interpretation of results.Results:The sensitivity and specificity of MSCTU and US for recognition of lesions presenting with macroscopic hematuria were 95.38%,83.33%and 81.54%,66.67%respectively and for those with microscopic hematuria were 96.08%,88.89%and 86.27%,77.8%respectively.The positive and negative likelihood ratios of MSCTU and US in macroscopic category were 5.73,0.055 and 2.46,0.277 respectively while for those in microscopic category were 8.65,0.044 and 3.88,0.176 respectively.In context to the sensitivity of MSCTU and US in patients presenting with macroscopic hematuriathedifferenceswere significant(McNemar's test,P=0.039)suggesting the tests are not similar whereas for those with microscopic hematuria the differences were not significant(Mc Nemar's test,P=2.68)indicatingsimilarity between these tests.Conclusion:Diagnostic efficacy of MSCTU is found to be far superior over US for patients presenting with macroscopic hematuria,thus current practice of using it as a first line modality seems to be justified.However,for those presenting with microscopic hematuria MSCTU and ultrasonography shows near to similar resultsin accordance to MSCTU,thus US alone seems sufficient to exclude significant urinary tract lesions.

Clinicopathological Analysis of 155 Patients with Persistent Isolated Hematuria

Objectives To reveal etiologies of persistent isolated hematuria （PIH） through ultrastructural pathological examination, to disclose clinicopathological correlation in cases with PIH, and to summarize appropriate management of patients with PIH. Methods we retrospectively studied 155 P1H patients receiving renal biopsy between January, 2003 and December, 2008 in Peking Union Medical College Hospital. All the clinical data and follow-up result were analyzed. Results All subjects included 38 children and 117 adults, with mean age of 11.38±3.25 years for children and 35.17±8.44 years for adults. Thin basement membrane nephropathy （TBMN） was the most common pathology （55.3% of children and 49.6% of adults）, followed by IgA nephropathy （18.4% of children and 32.5% of adults, mainly grade 2-3） and mesangial proliferative glomerulonephritis （MsPGN） without IgA deposition （13.2% of children and 12.8% of adults）. Besides, A1port syndrome （2.6% of children） and membrane nephropathy （2.6% of children and 0.9% of adults） were demonstrated as other causes of PIH. Elevated mean arteral pressure or protein excretion rate, as well as episodic macrohematuria, indicated higher risk for MsPGN rather than TBMN. On the other hand, severity of microhematuria was irrelevant to pathological types of PIH. Totally, 86 patients were followed up and 37 cases therein stayed on track for long term （mean duration 41.11±28.92 months, range 8-113 months）. Most cases had benign clinical course except 3 cases with TBMN, 5 cases with IgA nephropathy, 1 case with MsPGN （without IgA deposition）, and 1 case with Alport syndrome, who developed hypertension or proteinuria. All of them were administered timely intervention. Conclusions Close follow-up should be required as the primary management for PIH. Equally important is careful monitoring for early identification of undesirable predictors; while renal biopsy and other timely intervention are warranted if there is hypertension, significant proteinuria or renal impairment.

Superselective embolisation of bilateral superior vesical arteries for management of intractable hematuria in context of metastatic bladder cancer

Hematuria due to locally advanced or metastatic bladder cancer is a common condition and is often a management problem.Percutaneous embolisation is a mini-invasive option to handle this situation.We report a case of a patient with a metastatic bladder cancer and who presented with an abundant hematuria and severe anemia.After failure of endoscopic resections and“flush”of radiotherapy haemostatic and refusal of cystectomy by the patient,he was treated by superselective embolisation of bilateral superior bladder arteries with excellent immediate results.The technique is safe and effective in the short term.The longterm effectiveness requires further investigation.

Intractable hematuria due to giant prostatic hyperplasia effectively treated with prostatic artery embolization

Giant prostatic hyperplasia(GPH)is a rare pathology traditionally treated with an open suprapubic prostatectomy.This procedure is risky,and fatal hemorrhagic complications can occur.Often,patients with GPH present with diminished renal function due to obstructive nephropathy,making them unfit for less invasive endovascular therapies using traditional contrast agents.Here we present a case of a patient with intractable hematuria due to GPH,as well as diminished renal function,who was successfully treated using prostatic artery embolization with CO2 digital subtraction arteriography as a contrast agent.

Post-coital gross hematuria： an unusual presentation of benign prostatic hyperplasia

Aim： To describe an unusual symptom of benign prostatic hyperplasia （BPH）. Methods： A patient presented to our urology clinic having experienced post-coital gross hematuria for 2 years. He had not experienced lower urinary tract symptoms （LUTS）. A series of examinations were performed to determine the source of bleeding. Results： The prostate was defined as the active bleeding source responsible for the patient＇s post-coital hematuria. Endoscopic fulguration did not alleviate the symptom. The use of dutasteride, a dual inhibitor of 5α-reductase, solved the problem. Conclusion： This study reports for the first time that post-coital gross hematuria is one of the clinical presentations of BPH, which can be successfully treated with 5α-reductase inhibitor.

The following is an introduction of his experience in treating chronic nephritic hematuria.

Macroscopic hematuria as a presentation of gestational trophoblastic neoplasia in an adolescent woman

Gestational trophoblastic neoplasia (GTN) is a hemorrhagic malignancy with highly rapid potential metastasis via hematogenous spreading. Renal metastasis is of infrequent occurrence. Among previous case reports of renal metastasis in GTN, this is the youngest woman presenting a large renal lesion concurrent with pulmonary and brain metastases. Disease remission had been achieved by treatment with combined chemotherapy and whole brain radiation, although acute myeloblastic leukemia (AML) developed later.

Multi-Detector Row Computed Tomography Urography (MDCTU) in the Evaluation of Microscopic Hematuria in Adults

Multi-detector row computed tomography urography (MDCTU) becomes the imaging modality of choice for evaluation of the kidneys and urinary tract. The aim of this study was to discuss and illustrate the role of MDCTU, on a 32-row CT scanner in the evaluation a variety of entities that were frequently associated with microscopic hematuria in adults. This prospective cohort study was performed in the period of August 2013 to October 2014. Fifty positive participants to microscopic hematuria were examined at the radiology department of Alnilin Diagnostic Medical Center and Antalya Medical Center. Computed tomography urography (CTU) scanning was performed using two powerful performances, high speed multi-detector row on 32-row CT scanners (Siemens Healthcare Global, Somatom Emotion Duo Eco). Statistical analysis was done through the standard Statistical Package for the Social Sciences (SPSS Inc., Chicago, IL, USA) version 15 for windows. MDCTU established the correct cause of microscopic hematuria in (44;88%) of participants. In (6;12%) of participants, no cause of hematuria was identified based on the standard of references. The causes of hematuria in (41;82%) participants were diseases in the upper urinary tract, while urinary bladder neoplasms (2;4%) and diverticulum (1;2%) were the causes of hematuria (3;6%) in the lower urinary tract. Thirty two-row MDCTU scanner demonstrated satisfactory results in the investigation of microscopic hematuria, being able to demonstrate a wide spectrum of diseases affecting the urinary tract is the main advantage of the technique.

Relationship between Microscopic Hematuria and Inferior Vena Cava Reflux on Color Doppler Ultrasonography

We examined the relationship between microscopic hematuria and inferior vena cava (IVC) reflux. Transabdominal color Doppler ultrasonography of the IVC was performed in the supine position with the convex probe positioned perpendicular to the upper abdominal wall, and the extent of reflux into the IVC with each heart beat was examined near the diaphragm. A total of 171 patients were studied who had no diseases that could cause hematuria, and no symptomatic gross hematuria. The relationship between the existence and severity of IVC reflux and urine occult blood was examined. The 98 males included 50 subjects without IVC reflux and 48 with reflux, while the 73 females included 24 without IVC reflux and 49 with IVC reflux, respectively. The occurrence of IVC reflux was unrelated to age, but the prevalence of reflux was significantly higher in females than males. As the grade of IVC reflux increased, there was an increase in the prevalence and the severity of hematuria in both males and females. In conclusion, IVC reflux could be related to the occurrence of microscopic hematuria. Renal or urinary tract congestion secondary to IVC reflux may be one of the factors contributing to hematuria.

Case of purine nucleoside phosphorylase deficiency presented with hematuria

Purine Nucleoside Phosphorylase (PNP) deficiency is a rare autosomal recessive metabolic disorder. In PNP-deficiency disorder, the deficient enzyme leads to accumulation of toxic metabolites, especially in lymphocytes and the metabolites exert toxic effect on T-cell generation. Purine nucleoside phosphorylase deficiency causes decreased numbers of T cells and lymphopenia. The patients suffering from PNP-deficiency may be admitted with recurrent infections, as well as neurological and autoimmune findings. We hereby presented a case admitted with the symptom of hematuria in which we established the diagnosis of PNP-deficiency early on the basis of detection of lymphopenia and low level of uric acid.

Prevalence of Hematuria among Emergency Department Healthcare Workers

Background: In Taiwan, emergency departments are so busy that it is not uncommon for staffs (doctors and nurses) to be deprived of their lunch breaks or breaks to go to the restroom. As a consequence, during their busy shifts some emergency department healthcare workers choose to limit their water intake and no time to micturate which are both risk factors of urinary tract infection or urolithiasis. Hematuria is a common laboratory finding due to urinary tract infection and urolithiasis. Objective: To assess the prevalence of hematuria among the emergency department healthcare workers, we conducted a retrospective study in a district hospital in Taiwan. Documented data included those of healthcare workers who worked in the emergency department, as well as other departments of the same hospital. Methods: We reviewed the three-year records of general body checkup of hospital staffs who served in the emergency room and other departments of the same hospital between January 1, 2009 and December 31, 2011. Statistical software SPSS statistical analysis of survey data recovery is applied;data and test results by the questionnaire analysis patterns are associated with the urinary system abnormalities to ANOVA analysis to explore the hospital group whether there is a significant sex differences, and the other to analyze and verify the correlation analysis to the Scheffe post-hoc comparison method. Results: A higher prevalence of hematuria was observed among emergency department healthcare workers when compared with their colleagues who work in other departments of the same hospital. Female workers have higher risk of urinary system abnormalities than male workers. Nurses in the urinary system abnormalities are higher than other positions category. Shift work system has a negative effect on the urinary system. Conclusion: In conclusion, hematuria is more prevalent among emergency department healthcare workers than healthcare workers working in the inpatient wards. Hematuria might well be due to urinary tract infection which in turns caused by the overwhelmingly busy nature of the emergency department duty that deprived the emergency department healthcare workers from frequent voiding and sufficient intake of fluid.

Selective Internal Iliac Artery Oxaliplatin Infusion： Another Facultative Treatment to Unremitting Hematuria in Stage T4 Bladder Carcinoma

OBJECTIVE To observe and evaluate the value of utilizing selective internal iliac artery infusion and selective internal iliac artery embolization for the treatment of unremitting gross hematuria of stage T4 bladder carcinoma. METHODS Fifty-eight stage T4 bladder carcinoma patients were selected. The patients were grouped to the TAI group and the TAE group. The main symptom of hemorrhage was gross hematuria. None of the patients in our study could receive trunk embolization. The infusion plan was oxaliplatin （100 mg/m2） and epirubicin （EPI 50mg/m2）. Embolization was done with coils or strips of gelatin sponge. The duration of gross hematuria was observed. Routine urinalysis and routine blood examination were performed. EORTC QLQ-C30 was used to evaluate the quality of life before and after treatment. RESULTS Gross hematuria and hematuria by light microscope in all patients were reviewed. Resolution time of gross hematuria in the TAI group was 6.7 ± 1.8 days and that in the TAE group was 3.5 ± 0.7 days. The changes in routine urianlysis, routine blood examination and EORTC QLQ-C30 are shown in Figs.l-3. Gross hematuria disappeared in both groups within 7 days after treatment, but the time for the gross hematuria to resolve in the TAE group was much less than that in TAI group （t = 2.51, P 〈 0.01）, and there were no significant differences in the 7th and 21st day between the 2 groups. On the 90th day, the number of erythrocytes in the urine was near 30, close to gross hematuria. The EORTC QLQ-C30 scores decreased after interventional therapy in both groups, which means that quality of life was increased, but there were no significant differences between the 2 groups. CONCLUSION Selective internal iliac artery infusion and selective internal iliac artery embolization are safe, and, in our study, therapeutic efficacy was satisfactory in treating unremitting gross hematuria of stage T4 bladder carcinoma in patients who could not receive trunk embolization. TAE can stop gross hematuria in the short term, but it can be used just once and the long-term therapeutic effect is not satisfactory. TAI had a therapeutic effect similar to TAE, but for a shorter duration, and TAI can be performed multiple times. TAI is one of the facultative treatments for treating gross hematuria of stage T4 bladder carcinoma.

Safety and efficacy of transcatheter arterial embolization for management of refractory hematuria of prostatic origin

Objective: To estimate the safety and efficacy of transcatheter arterial embolization(TAE) in the treatment of refractory hematuria of prostatic origin(RHPO).Methods: This retrospective study included 23 patients who underwent TAE for RHPO between May 2013 and August 2021. Technical and clinical success rates were calculated, and arteriogram findings and complications were detected.Results: Embolization was performed 24 times in 23 patients. Technical success was achieved in 24/24(100%)embolization procedures. Contrast agent extravasation was detected during 2 of the 24 angiographic procedures.Bilateral embolization was performed in 23(95.8%) of the 24 procedures. The clinical success rate was 21/23(91.3%), and hematuria stopped 1–4 days after TAE. No serious complications were observed.Conclusion: TAE is a safe and effective minimally invasive technique for treating patients with RHPO.

Isolated Gross Hematuria or Associated to Acute Retention of Urine as a Sign of Urologic Malignant Pathology

The causes oflGH （Isolated gross hematuria）, as the only symptom or associated with ARU （acute retention of urine） caused by clots in the urinary tract in patients who do not have a previous diagnosis of urological malignant pathology and to study the immediate mortality in patients with that sign are described. A descriptive observational study of the etiologies of patients shows the above mentioned symptomatology from the 1 st of January to the 30th of June of 2008 in the Emergency Department which received follow-up treatment up to December 2010. It also describes the mortality before the definitive diagnosis and the days between receiving attention in the Emergencies Department and the diagnostic tests. One hundred and four cases with the criteria described above were evaluated. Of these, 20.0% turned out to have bladder, prostate or kidney cancer; the bladder being the most affected organ. Of all the pathology, benign and malignant, the most frequent one is the benign hypertrophy of the prostate （49.8% of the total）. Of the total, 4.8% of the patients died in the following weeks before finishing the diagnostic study. Isolated gross hematuria is a clinical symptom closely related to urological malignant pathology and it does not have an insignificant mortality rate in a short period of time. For these reasons it is necessary to accelerate the diagnostic tests as soon as the patient presents the symptom.

The Comparison of Acute Clinical Outcome between 30 and 40 Sessions of Hyperbaric Oxygen Therapy for Management of Visible Hematuria from Radiation-Induced Hemorrhagic Cystitis

Background: Radiotherapy is one of the most popular treatments for pelvic malignancy, which causes patients suffering from the adverse effect such as cystitis, hematuria, proctitis, hematochezia and distal ureteric stricture. The hematuria condition from radiation-induced hemorrhagic cystitis is the most common adverse event suffering the patients, losing properties, wasting time, and deteriorating quality of life. One of the most effective treatments for radiation-induced hemorrhagic cystitis is the hyperbaric oxygen therapy with no necessity for patients to be hospitalized, no need of anesthesia use, and also non-invasion. However, it requires that patients spend 90 - 120 minutes a day for 40 days administered out-patient treatment session. The transportation cost as well as the accommodation one will greatly burden the self-pay health care patients. In addition, there is still no definite standardized number of HBOT treatment session assignment at present. Objectives: To compare the treatment outcome (bladder mucosal characteristics, red blood cells in urine) between 30 and 40 sessions of HBOT for treatment of radiation-induced hemorrhagic cystitis. Methods: Prospective cohort observational study of patients (n = 15) who were diagnosed with radiation-induced hemorrhagic cystitis that were treated with hyperbaric oxygen therapy in Somdechprapinklao Hospital between October 2020 and September 2021. We compared the parameter about hemoglobin concentration, red blood cell number in urine during the course of HBOT treatment every 10 sessions and cystoscopic finding severity as EORTC/RTOG classification for radiation-induced hemorrhagic cystitis in Table 1 before treatment, and after 30 and 40 sessions of treatment. Results: From 15 of treated patients, 93.3% of patients had evidence of posterior wall lesion. The mean duration from radiotherapy (radiation and brachytherapy) to the first episode gross hematuria is 112 months. This study shows no statistically different cystoscopic findings as EORTC/RTOG classification for radiation-induced hemorrhagic cystitis after 30 and 40 sessions of HBOT (p = 0.653) and statistically significant improvement after the treatment of more than 30 sessions (p = 0.008). No relationship was found with the hemoglobin concentration and red blood cell number in urine during the course of HBOT. Conclusions: Radiation-induced hemorrhagic cystitis can be treated with HBOT. There is no different treatment outcome between 30 and 40 sessions of HBOT.

Urological Emergencies at the University Hospital of Brazzaville: Epidemiological, Clinical, and Therapeutic Aspects

Introduction: Urological emergencies play a significant role in the medical and surgical activity of a urology department. The objective of this study was to determine the hospital prevalence of urological emergencies at the University Hospital of Brazzaville (CHUB), identify the different pathologies requiring urgent care, and list the various therapeutic methods. Patients and methods: A retrospective study of patients admitted to the medical and surgical emergencies department of CHUB over a 5-year period. Patient records admitted and treated for a urological emergency were included. The variables studied were the frequency of urological emergencies, patient age at admission, gender, nature of the emergency, and various therapeutic options. Results: Urological emergencies accounted for 4.3% of all medical and surgical emergencies. The mean age was 57 ± 28 years with a range of 3 to 93 years. The male-to-female ratio was 7.1. The most common conditions were urinary retention (54.67%), hematuria (17.20%), and renal colic (8.13%). Therapeutically, surgical urinary drainage was dominated by cystostomy. Conclusion: Urological emergencies are infrequent at the University Hospital of Brazzaville. Their management is often delayed.
