Modified cystectomy with preservation of erectile andejaculatory functions in men with non-malignant bladder diseases

Objective: To evaluate the effect of a modified cystectomy in the preservation of erectile and ejaculatory functions in men with non malignant bladder diseases. Methods: Seven cases with average age of 27 years presented with bladder diseases necessitating cystectomy, including 2 tuberculous contractile bladder, 1 extensive polypoid cystitis glandularis and 4 late stage neurogenic bladder. We performed a modified simple cystectomy reserving both vasa deferentia, seminal vesicles, prostate and neurovascular bundles with the construction of an Indiana pouch or ileal neobladder. Results: The average operation time was 5 h 45 min. There were no perioperative complications. With a follow-up of 9months to 60 months, the erectile and ejaculatory functions were normal in all the cases. All patients remained completely continent without dysuria. The upper urinary tract was in good condition 3 and 24 months after operation. Conclusion: Modified cystectomy with preservation of the vasa deferentia, seminal vesicles,

Objective To observe the histopathologic characteristics of 2 micron continuous wave laser transurethral partial cystectomy for the treatment of bladder tumor. Methods A total of 54 patients with 65 bladder tumors underwent 2 micron laser via transurethral by caudal or surface anesthesia from October 2007 to December 2008. It included 41 male and 13 female cases, and the age ranged from 27 to 81 years old with a mean of (66.2±12.4) years old. The operation evaporated and exsected the wall of urinary bladder, including tumor, submucosa and all muscular layers. Specimens were sent for pathology examination. The histomorpholagic changes of raw surfaces were observed 1 week, 1 month, 3 months, 6 months and 1 year postoperation by cystoscopic and pathologic examinations. Results All the patients tolerated in the operation. Clinical stages of the tumor: T1 for 42 cases, T2 for 12 cases. All cases were followed-up for 1 to 14 months, with a mean of 8. 5 months. Tumor recurrences were found in 2 cases, no one had recurrence in situ. The tumor, submucosa and all muscular layem can be resected completely by 2 micron continuous wave laser transurethral partial cystectomy. Pathologic staging can be judged correctly.The umbilication raw surface were infiltrated by fibrous connective tissue and chronic inflammatory cells 1 week postoperation. The umbilication changed shallow and transitional epithelial cells began to cover it 1 month postoperation. The umbilication dispeared and transitional epithelial cells cover the raw surface 3 months postoperation. There was no difference between the raw surface and normal bladder mucosa.Conclusions 2 micron continuous wave laser for the treatment of bladder tumor can get the same clinical result as partial cystectomy. The pathologic staging can be judged correctly by the specimens.

Objective To analyze the etiology, clinical diagnosis and outcomes of 6 cases of multifocal urothelial carcinomas following transplantation. Methods A retrospective analysis was performed on 6 cases of multifocal urothelial carcinomas following renal transplantation in our center. Results Six patients were diagnosed as having multifocal urothelial carcinomas, including 1 case of related renal transplantation. Five cases were diagnosed by painless gross hematuria 2～48 months after renal transplantation, and I patient was diagnosed as having bladder tumors by B-uhrasound. All lesions happened un-simultaneously, from 1.5～16 months, and each case accepted operation 2～5 times. One case accepted radical cystectomy and cutaneous ureterostomy of the graft, and one accepted radical cystectomy, cutaneous ureterostomy of the graft and urethrectomy. All of 6 cases received OKT3 or Daclizumab as the induced-immunosuppressive therapy and tacrolimus or cyclosporine A + mycofenolate mofetil + steroid as the maintenance therapy. Intravesical chemotherapy started in all patients immediately after the surgery. All operations were successful and most patients got satisfactory results. Conclusions Kidney recipients have a higher rate of transitional cell carcinomas which are characterized by easy metastasis, and mostly have unsatisfactory prognosis. Kidney recipients with hematuria should be examined carefully with cystoscopy, retrograde pyelography and cystourethroscopy. A routine examination at regular intervals after transplantation is very important.

Small cell carcinoma of the urinary bladder: a case report]

We report a case of small cell carcinoma of the urinary bladder. A 60-year-old man with microscopic hematuria was referred to our hospital. Cystoscopy revealed a sessile tumor on the left lateral wall of the urinary bladder. The patient underwent transurethral resection of the bladder tumor (TUR-Bt). Because of muscle invasion (pT2), total cystectomy was recommended, but was not performed because the patient would not give consent for the operation. Six months after TUR-Bt, invasive bladder tumor recurred and total cystectomy was performed. Pathological examination of the operative specimen revealed small cell carcinoma. Adjuvant combined therapy of irradiation and chemotherapy (nedaplatin and etoposide) was ineffective. Metastases to retroperitoneal lymph nodes, lung and liver were detected soon after the adjuvant therapy. The patient died 15 months after his first visit to our hospital.
