- Purpose Urinary diversion is an alternative treatment for conditions such as radiation and interstitial cystitis, neurogenic bladder and severe incontinence. The subsequent complication rate may reach 60% due to the retained nonfunctional bladder. The subsequent cystectomy rate may be as high as 20% because of pyocystis, hematuria, pelvic pain and rarely bladder cancer. We describe simple cystectomy involving bladder removal without the adjacent structures, avoiding deep pelvic dissection. Materials and Methods Ileal conduit or continent diversion and simple cystectomy were performed for crippling bladder symptoms secondary to neurogenic bladder, pelvic radiation, hematuria and/or severe incontinence in 12 women and 7 men with a mean age of 63 years. We performed urinary diversion and simple cystectomy only when all conservative means of treatment had failed. The majority of patients had multiple co-morbidities, previous surgeries and pelvic radiation. An average of 5 conservative procedures (range 2 to 10) had been done before simple cystectomy. None of these patients had urothelial malignancy. Simple cystectomy was done concomitantly with urinary diversion in 13 cases and later as a separate procedure in 6 due to complications of a retained nonfunctional bladder. Results Mean followup was 15 months. No mortality was associated with surgery. For simple cystectomy only mean operative time was 30 minutes and mean estimated blood loss was 300 cc. Median time from symptom presentation to cystectomy was 35 months and mean hospital stay was 7 days. In all cases symptoms were dramatically alleviated. No morbidity was directly attributable to simple cystectomy. Conclusions Simple cystectomy is well tolerated and should be performed at urinary diversion to avoid later complications of the retained bladder. Technically this procedure is not demanding and is relatively easy to perform even after previous pelvic radiation.
