PARTIAL CYSTECTOMY AS AN ALTERNATIVE TO CYSTECTOMY FOR EXTENSIVE URINARY BLADDER INVOLVEMENT BY LOCALLY ADVANCED COLORECTAL CANCER

Abstract

The volume of an operation on the urinary bladder (UB) in case of its extensive involvement due to locally advanced colorectal can-cer varies from partial cystectomy to cystectomy. The results of a morphological examination of 18 patients after pelvic exenterationdemonstrated true invasion into the urinary bladder wall only in 7 (38.9%) cases. This created preconditions for organ-preservingtreatment. Combined operations with partial cystectomy were performed in 37 patients. Pathology showed true tumor invasion intothe urinary bladder wall in 13 (35.1%) cases. The bladder volume was 55.2±17.1 ml after surgery and 175 to 360 (230±31.2) mlfollowing autohydrotraining with pharmacological support made 3 months after surgery. No patient had recurrent urinary bladderdisease. The surgical results suggest that organ-preserving treatment does not violate the oncological radicalism principles and is aserious alternative to cystectomy: Firstly, there is no need for the technically complex stage of an operation - to create a urinaryreservoir. Secondly, urination is preserved by its natural way; there are no signs of urinary incontinence, which ensures the betterquality of life.
