[Two cases of the nephrogenic adenoma of the bladder].

Nephrogenic adenoma is a relatively rare, benign tumor of the urinary tract. We experienced two cases of nephrogenic adenoma originating in the bladder. The first patient was a 61-year-old man. Two papillary tumors were found on the bladder. Transurethral resection of the bladder tumor (TUR-Bt) was performed. The second patient was a 72-year-old man who had a history of TUR-Bt for the bladder tumor and a history of left nephroureterectomy for left ureteral tumor. Cystoscopy showed a papillary tumor on the top of the bladder wall and TUR-Bt was performed. In both cases, the histopathological diagnosis was the nephrogenic adenoma. Our cases are the 40th and 41st cases of the nephrogenic adenoma of the bladder reported in the Japanese literature.

[A case of transitional cell carcinoma of the bladder in a juvenile patient].

A 17-year-old male was referred to our hospital with the chief complaint of right back pain. Cystoscopic examination revealed a papillary tumor on the posterior wall following detection on screening ultrasound examination revealed a tumor in the bladder. Transurethral resection of the bladder tumor was performed. Histological examination of the excised tumor revealed transitional cell carcinoma, grade 1, pTa. No recurrence has been observed for about 1 year postoperatively.

Case report: Cystoscopic use of cyanoacrylate glue for bleeding during transurethral resection of bladder tumors.

An 81-year-old woman with a history of nephroureterectomy and bladder cuff excision for grade 3 stage pT3N0M0 transitional-cell neoplasia presented with three bladder neoplasms. She also had symptomatic varicose veins in the lower extremities and received low-molecular-weight heparin. During transurethral resection of the tumors, deep ablation of the base of one lesion resulted in significant arterial bleeding that could not be controlled with normal endoscopic techniques. On the basis of previous positive experience, we endoscopically injected 3 mL of cyanoacrylate glue (Glubran 2) deeply (5 mm) into the tissue surrounding the bleeding site, making four injections with a device used for collagen injections. The area was irrigated with mannitol and sorbitol, and within a few seconds, there was complete remission of bleeding. We waited a further 90 seconds with the bladder distended to allow the substance to lose its adhesive properties so as to avoid having the bladder walls stick together. The catheter was removed on the third day, with resumption of micturition and clear urine. This appears to be the first case of cystoscopic use of cyanoacrylate glue to control bleeding.

[Preliminary results of the treatment of high grade (T1G3) superficial tumors of the bladder with transurethral resection].

OBJECTIVE: To examine the results of monotherapy with TUR in the treatment of primary T1G3 transitional cell carcinoma (TCC). METHODOLOGY: Thirty-two patients with primary TCC of the bladder were allocated into a surveillance program. Risk factors for progression to muscle-invasive disease were determined. Immediately, projections of disease-free and progression-free survival were calculated. RESULTS: Five patients (15.6%) were lost in follow-up. Twenty-three (85%) had superficial recurrences. Four patients (14.8%) progressed to muscle-invasive or metastatic disease. No independent risk-factors for progression were disclosed. Median disease-free survival was 8 months. Projection of the risk of recurrence at 79 months was 84.9%. Median time to progression has not been reached yet. Projection of progression at 79 months was 46.3%. CONCLUSIONS: The above mentioned treatment schedule is associated with very high recurrence rates. In addition, recurrences are very frequent. Nevertheless, in the medium run, projections of progression suggest that surveillance can be an alternative to other treatments in the management of T1G3 TCC of the bladder.

Radiotherapy alone or radiochemotherapy with platin derivatives following transurethral resection of the bladder. Organ preservation and survival after treatment of bladder cancer.

PURPOSE: Multivariate analysis of prognostic factors influencing survival and bladder preservation after radiochemotherapy for bladder cancer following transurethral resection of the bladder (TURB). PATIENTS AND METHODS: At the University Hospital of Erlangen 333 patients with bladder cancer were treated with either radiotherapy alone (RT, n = 128) or platin based radiochemotherapy (RCT, n = 205) after TURB between 5/1982 and 5/1996. Two-hundred and eighty-two curative patients, with either muscle invasive or T1-high risk cancer, were analyzed. Median age was 66 years, median follow-up is 7.5 years. Uni- and multivariate analysis was performed for age, grade, R-status after initial TURB, T-category and treatment modality relevant to the endpoints initial response, survival and bladder preservation. RESULTS: Treatment related mortality was below 1%. Complete remissions were achieved at 57%, 70%, and 85% after RT or RCT with carboplatin or cisplatin. This difference was multivariately significant. Further significant prognostic factors were pT-category and R-status. For all patients survival was 59% and 43% after 5 and 10 years. 79% of survivors could keep their own bladder. Five-year survival rates after RT alone, RCT with carboplatin or cisplatin were 47%, 57%, and 69%, respectively. This was univariately significant. The only multivariately significant factor for survival and bladder preservation was the R-status after initial TURB. CONCLUSIONS: Treatment of bladder cancer by TURB and RT/RCT is an alternative to primary cystectomy. The addition of chemotherapy leads to significantly more complete remissions and better survival. Initial TURB is recommended to be as radical as possible.

Starch granulomas after transurethral resection of bladder tumors.

Starch granulomas have been observed in 3 patients in a series of 140 under treatment for bladder cancer during the period 1949 to 1969 in one hospital. The lesions were observed at the fourth or subsequent transurethral procedure, suggesting strongly that the starch had been introduced at a previous transurethral procedure. The granulomatous reaction may simulate a recurrence of the initial bladder tumor.

Endoscopic procedures in the treatment of urologic disorders in children.

Cystoscopy has been a well established procedure in adult urology for years and more recently for the endoscopic evaluation of the lower urinary tract of infants and children. Utilizing small caliber cold light endoscopes and resectoscopes, therapeutic manipulations are readily possible. Among these are extraction of ureteral stones, lithotripsy of bladder calculi, transurethral resection of bladder tumors, as well as transurethral incision and resection of bladder-neck obstructions, urethral valves and urethral stenoses. The excellent results obtained in the treatment of infravesical urinary obstruction have contributed to the importance of transurethral surgery in pediatric urology.

Cooperative studies of chemoprophylaxis after transurethral resection of bladder tumors.

Large cooperative trials are more likely than series studied by small groups to bring about significant progress in the field of intravesical adjuvant chemotherapy of superficial bladder tumor. Multicenter randomized trials involving large numbers of patients have been conducted in Europe by the EORTC Urological Group. The Group's main objectives were to compare the efficacy of thio-TEPA, VM-26, epodyl, Adriamycin, and cisplatin, against no treatment, and to study the prophylactic effect of oral pyridoxine and evaluate the main prognostic factors. The results obtained so far are reported. Preliminary information is also given about the Blinst study, a multicenter open investigation of local chemotherapy with doxorubicin (Adriamycin), with special reference to evaluation of the importance of different modalities of treatment with a single drug.
