Intravesical explosion during transurethral resection of bladder tumor:A case report

BACKGROUND Intravesical explosion during transurethral resection of bladder tumor(TUR-BT)is a very rare complication,and it may result in rupture of the bladder,which usually requires surgical correction and causes a potential threat to the patient’s life.CASE SUMMARY This paper reports a case of intravesical explosion during TUR-BT.Combined with the literature review,the risk factors are analyzed and measures of prevention and treatment are discussed.CONCLUSION Although rare,intravesical explosions can cause serious consequences,and the loud explosion can also lead to a profound psychological shadow on the patient.Urologists must be aware of this potential complication.Careful operative techniques and special precautions can reduce the risk of this complication.

Transurethral Resection of Bladder Tumours: Results and Outcomes

Aim: This study aimed to determine the demographic, clinical, paraclinical, therapeutic, and evolutive characteristics of patients with bladder tumors who underwent transurethral resection of bladder tumors (TURBT) at a urology center in Douala, Cameroon. Patients and Methods: This was a retrospective study carried out from 2015 to 2019 on 32 patients with bladder tumors that were managed at the Centre medico-chirugical d’urologie in Douala, Cameroon. The relevant data were obtained from patients’ clinical records. Results: A total of 32 patients (25 men and 7 women) aged 29 - 75 years were included in this study. The mean age of the study participants was 58.63 ± 11.00 years. Among our study participants, there were 10 smokers (31.25%). Eight (25%) of them had occupational exposure while 2 (6.25%) had residential exposure to bladder cancer. Thirty (93.75%) presented with hematuria, 2 (6.25%) presented with recurrent urinary tract infections, and 1 (3.13%) presented with acute urinary colic. Nineteen (59.38%) of them were anemic, with 4 (12.5%) requiring blood transfusions. Twenty-seven (84.38%) of them had pedunculated tumors while 5 (15.62%) had sessile tumors. The tumor diameters ranged from 1 cm to 5 cm, with a mean diameter of 2.75 ± 1.22 cm. Complete resection was performed in 27 (84.38%) participants while partial resection was performed in 5 (15.62%) patients. The early single instillation of intravesical chemotherapy with mitomycin was performed in 8 (25%) patients. Only one (3.13%) patient had a postoperative complication, and seven (21.88%) patients experienced tumor recurrence and underwent a second TURBT. Two (6.25%) of the 32 patients died and 30 (93.75%) survived. Conclusion: TURBT is the gold standard method of managing bladder tumors. This procedure is at the same time diagnostic and therapeutic for tumors that do not invade the walls of the urinary bladder.

Cryoablation techniques in bladder cancer: A review

Bladder cancer(BC)ranks as the tenth most common cancer globally.Histopathologically,BC is broadly categorized into urothelial and non-urothelial BC.Urothelial carcinoma represents over 90%of BC in most regions worldwide.The standard treatment procedure for diagnosing and treating non-muscle-invasive bladder cancer(NMIBC)is transurethral resection of bladder tumors(TURBT).Currently,the standard of care for muscle-invasive bladder cancer(MIBC)is neoadjuvant chemotherapy followed by radical cystectomy.Cryoablation therapy is a medical technique that uses extremely low temperatures to destroy diseased tissue.This treatment serves as a therapeutic tool for both benign and malignant diseases in organs such as the kidney,prostate gland,lung,liver,and breast,and is particularly effective for unresectable tumors,offering less trauma,quick recovery,good tolerability,and symptom control.However,cryoablation has its limitations.Over the past few years,cryoablation therapy has emerged as a new method for treating early BC.This treatment is minimally invasive,precise,and offers quick recovery,providing patients with a new treatment option.Although randomized studies are still limited,increasing evidence suggests its potential application in bladder cancer combined with transurethral resection(TURBT)or medication.Cryoablation is not standard therapy for bladder cancer.Treatment decisions should be discussed by a multidisciplinary team of urologists,oncologists,and interventional physicians and require more randomized controlled trials to define patient selection criteria and treatment approaches.

Treatment and surveillance for non-muscle-invasive bladder cancer:a clinical practice guideline(2021 edition)

Non-muscle invasive bladder cancer(NMIBC)is a major type of bladder cancer with a high incidence worldwide,resulting in a great disease burden.Treatment and surveillance are the most important part of NIMBC management.In 2018,we issued“Treatment and surveillance for non-muscle-invasive bladder cancer in China:an evidencebased clinical practice guideline”.Since then,various studies on the treatment and surveillance of NMIBC have been published.There is a need to incorporate these materials and also to take into account the relatively limited medical resources in primary medical institutions in China.Developing a version of guideline which takes these two issues into account to promote the management of NMIBC is therefore indicated.We formed a working group of clinical experts and methodologists.Through questionnaire investigation of clinicians including primary medical institutions,24 clinically concerned issues,involving transurethral resection of bladder tumor(TURBT),intravesical chemotherapy and intravesical immunotherapy of NMIBC,and follow-up and surveillance of the NMIBC patients,were determined for this guideline.Researches and recommendations on the management of NMIBC in databases,guideline development professional societies and monographs were referred to,and the European Association of Urology was used to assess the certainty of generated recommendations.Finally,we issued 29 statements,among which 22 were strong recommendations,and 7 were weak recommendations.These recommendations cover the topics of TURBT,postoperative chemotherapy after TURBT,Bacillus Calmette–Guérin(BCG)immunotherapy after TURBT,combination treatment of BCG and chemotherapy after TURBT,treatment of carcinoma in situ,radical cystectomy,treatment of NMIBC recurrence,and follow-up and surveillance.We hope these recommendations can help promote the treatment and surveillance of NMIBC in China,especially for the primary medical institutions.

Searching for the Lost Ostium: A Morphometric Analysis of the Ureteral Ostia Distribution in Normal and Thickened Bladders and Its Applications in Endourology

Introduction: The ureteral ostia may not be easily identified in urological endoscopic procedures, leading to an incomplete diagnosis of urinary tract diseases or a predisposition to iatrogenic lesions. The purpose of our study is to evaluate the anatomical distribution of ureteralostia in normal bladders and those with thickened walls. Materials and Methods: We dissected 30 vesical-prostate blocks from human cadavers and identified the ostia of the bladder trigone. A computerized morphometric analysis was performed to measure the thickness of the detrusor muscle, the distances between the ureteral ostia themselves and the distances between each ureteral ostium (left—LUO and right—RUO) and the internal urethral ostium (IUO). The angle formed between the IUO and LUO/RUO was also recorded as well as the volume of the prostates. Results: Fifteen bladders with a non-thickened detrusor (6 mm) were identified. The average prostatic volume of the dissected blocks was 23.7 cm3. The distance between ureteral ostia, the distance from IUO to LUO, the distance from IUO to RUO and the angle formed between IUO and LUO/RUO in normal and thickened bladder were, respectively, 1.9 cm/2.2 cm (p = 0.09), 1.6 cm/1.6 cm (p = 0.82), 1.6 cm/1.7 cm (p = 0.79) and 77/91 (p = 0.17). Conclusions: Our study shows that there is no significant difference in the position of bladder ostia in healthy and thickened bladders. We believe that our findings may facilitate locating the ureteral orifices in situations where endoscopic identification is difficult.

Photodynamic Therapy Combined with Electrosurgical Resection for Recurrent Bladder Cancer

Bladder tumor is characterized by recurrent recurrence and distant metastasis,which determines the difficulty of completely curing bladder tumor.In recent years,the number of patients with bladder cancer is increasing,and the treatment of bladder cancer has become an important direction of clinical research.It is difficult to control bladder tumor by traditional therapy.Photodynamic therapy(PDT),as a new optical therapy,has gradually become the main method in clinical treatment of bladder tumor combined with transurethral resection of bladder tumor.In this paper,a patient with superficial recurrent bladder tumor was treated by photodynamic therapy combined with transurethral resection of bladder tumor.The advantages of photodynamic therapy in the treatment of bladder tumor and the selection of photosensitizer in the process of photodynamic therapy were discussed.After two recurrences,the patients chose photodynamic therapy.The tumors were resected one by one,and the wound was coagulated by roller electrode.After the drug was retained for 20 minutes,the bladder was empty.The spherical optical fiber was implanted into the bladder.The photodynamic energy was adjusted(light power 1.8 W,light time 1302 s).There was no recurrence after operation.Most bladder tumors are superficial tumors,and bladder is a cavity organ,which determines that bladder is an ideal organ for photodynamic therapy.As a targeted drug,photosensitizer is only absorbed by bladder tumor after being perfused into bladder.The photosensitizer forms reactive oxygen species through oxygen and kills tumor cells.Clinical practice has proved that PDT has its unique advantages for superficial and recurrent bladder tumors.As the first generation photosensitizer,xipofen also has selectivity in the treatment of bladder cancer.

Mechanism research of pirarubicin postoperative immediately bladder irrigation combined compound matrine injection on treating superficial bladder cancer

Objective:Investigate the mechanism of Pirarubicin postoperative immediately bladder irrigation combined compound matrine injection on treating superficial bladder cancer, thus to provide assistance for clinical therapy of superficial bladder cancer.Methods:A total of 90 cases of patients with superficial bladder cancer treated in our hospital were selected, and randomly divided to be control group and combination group, 45 cases for each. For patients in control group, treatment of Pirarubicin postoperative immediately bladder irrigation was provided after transurethral resection of bladder tumors. For patients in combination group, combined treatment of Pirarubicin postoperative immediately bladder irrigation and compound matrine injection were provided after transurethral resection of bladder tumors. T lymphocyte subsets, cytokines, liver and renal functions of patients in each group were detected before and after treatment.Results: No statistical difference showed on T lymphocyte subsets, cytokines, liver and renal functions between two groups of patients with superficial bladder cancer before and after treatment. Compared with prior treatment, CD8+, cytokines (IFN-γ and IL-2), liver function indexes (AST and ALT) and renal function indexes (BUN and Cre) were significantly increased in two groups of patients after treatment, while T lymphocyte subsets (CD3+, CD4+ and CD4+/CD8+) and cytokines (TNF-α, IL-6 and CRP) were significantly decreased. Differences showed statistical significance. After combined treatment given, T lymphocyte subsets (CD3+, CD4+ and CD4+/CD8+) and cytokines (IFN-γ and IL-2) in combination group were significantly higher than in control group after treatment, cytokines (TNF-α, IL-6 and CRP), CD8+, liver function indexes (AST and ALT) and renal function indexes (BUN and Cre) were significantly lower than in control group after treatment. Differences between the two groups showed statistical significance.Conclusion:Combination of Pirarubicin postoperative immediately bladder irrigation and compound matrine injection could enhance immune functions, improve inflammatory reactions and decrease chemotherapeutics toxicities for patients with superficial bladder cancer. It is of great significance on clinical therapy for those patients.

Holmium laser versus conventional transurethral resection of the bladder tumor

Background Transurethral resection of the bladder tumor （TURBT） remains the gold standard for non-muscle-invasive bladder cancer （NMIBC）. Laser techniques have been widely used in urology. This analysis aimed to assess the safety and efficacy of holmium resection of the bladder tumor （HoLRBT）vs. TURBT. Methods A systemic search of MEDLINE, Embase, Web of Science, and The Cochrane Library as well as manual bibliography searches were performed to identify the relevant studies. The pooled estimates of operation time, obturator nerve reflex rate, bladder perforation rate, bladder irrigation rate, catheterization time, hospital stay, and one- and two-year recurrence free survivals were calculated. Results Five studies were enrolled into our meta-analysis. No significant difference was observed in the operation time between groups （weighted mean difference （WMD） 1.01, 95% confidential interval （95% CI） -3.52-5.54, P=0.66）. The significant difference in the obturator nerve reflex （OR 0.05, 95% CI 0.01-0.04, P=0.004）, bladder perforation （OR 0.14, 95% CI 0.03-0.61, P=-0.009）, bladder irrigation （OR 0.13, 95% CI 0.04-0.45, P=0.001）, catheterization time （WMD -0.96, 95% C1-1.11 to-0.82, P 〈0.00001）, and hospital stay （WMD-1.46, 95% C1-1.65 to-1.27, P 〈0.00001）showed advantages of HoLRBT over TURBT. The 2-year recurrence free survival rate favors the HoLRBT group （OR 1.46, 95% CI 1.02-2.11, P=-0.04）. Conclusions As a promising technique, HoLRBT is safe and efficient, and showed several advantages over TURBT. HoLRBT can be used as an alternative procedure for TURBT in terms of low-grade papillary urothelial carcinoma or low-grade early TNM-stage urothelial carcinoma.

目的 对比经尿道膀胱肿瘤电切术(TURBT),探讨黏膜下小剂量注射吉西他滨(SIOG)联合TURBT治疗中高危非肌层浸润性膀胱癌(NMIBC)的治疗效果及药物经济学评价。方法 收集2015年1月1日至2020年8月31日本院270例中高危NMIBC患者(TURBT 213例,SIOG+TURBT 57例)的临床资料,应用倾向性评分匹配以1∶1的比例匹配,每组病例为52人,分析2组的临床疗效,核算其成本,构建1年为循环周期,1 000人10年的Markov模型对2组治疗方案进行药物经济学评价。结果 TURBT组患者3、6、12个月肿瘤未复发率和SIOG+TUR BT组患者3、6、12个月肿瘤未复发率分别为90.38%vs 100.00%、84.62%vs 98.08%、78.85%vs92.31%,术后6个月时肿瘤未复发率2组差异具有统计学意义(P <0.05),经log-r a n k检验,2组1年时肿瘤未复发率差异具有统计学意义(P <0.05)。TURBT方案和SIOG+TURBT方案累积人均成本分别为217 117.20元和190 701.12元,获得的健康效果分别为5.56质量调整生命年(quality-adjusted life years,QALYs)和5.77QALYs。与TURBT治疗方案相比,SIOG+TURBT治疗方案提高了0.21QALYs,节约了26 416.08元。SIOG+TURBT方案对于TURBT方案具有成本-效用优势。结论 与TURBT相比,SIOG+TURBT治疗中高危NMIBC具有更优的临床效果及经济性。
