Introduction: The tumour of the bladder is the third most frequent urological malignancy. Muscle invasive cancer can be cured by radical cystectomy. After removing the bladder; a sufficient urinary diversion should be performed.
Aim and method: The authors introduce the operative process of the pouch and their experiences with the procedure. The analysis of results were performed retrospectively.
Results: Between 1998 and 2005 the authors performed radical cystectomy in 76 patients followed by: Mainz pouch II urinary diversion. The average age of the patients was 59.8 (20-78) years. The distribution by gender was: 58 male, 18 female patients. The average pathological T stage was 2.3; 22 patients (29%) had metastatic lymph nodes. 94% of the cases were transitional cell cancers, 3 (4%) of them had adenocarcinoma and one leiomyosarcoma. Reoperation was carried out in 7 cases (9.2%) because of wound healing defects, and one patient was reoperated because of bleeding and ileus respectively. Transitionally nephrostomy was performed in 5 cases (6.5%) because of upper urinary tract dilatation due to a stricture of ureter anastomosis. The average survival period was 24.4 (1-98) months.
Conclusion: Urinary diversion Mainz pouch II provides for safe, continent diversion requiring no urine bag; with an acceptable QL (quality of life). On the basis of the low number of complications and the acceptable QL; the authors consider this method as appropriate.
