A total of 14 apparently healthy male Mongrel dogs were studied in two parts: the experimental and the clinical part. The experimental part was divided into group 1 (7 dogs) subjected to apical cystectomy with colocystoplasty and group 2 (3 dogs) were subjected to apical cystectomy with cystorrhaphy as a control group. The clinical part was consisted of 4 dogs: two were suffering from urinary bladder (UB) mass and two suffering from ruptured UB were subjected to colocystoplasty after total excision of masses and necrosed wall trimming. Colocystoplasty was performed by using 6 cm loop of descending colon with its own mesentery. The stability of the augmentation technique was evaluated via clinical findings, ultrasonographic examination, positive contrast retrograde cystography and kidney function test before surgery and at 1st, 3rd, 7th, 15th and 30th days postoperation. Postoperation follow up of the group 1 and the clinical part revealed gradual improvement of urination frequency from 2-3 urinations/hour during the first week to 1-2 urinations/4 hours between the 20th and 30th days. The mean UB capacity at 30th day showed non-significant (P≤0.05) difference with the normal mean. Ultrasonographic and radiographic examinations at 30th day showed fully distended UB, superiorly located augmented colon segment and intact line of anastomosis. No signs of leakage were noted ultrasonographically or radiographically and there were no signs of rejection. In conclusion, colocystoplasty as a technique for bladder augmentation provides promising results in compensating impaired filling capacity and subsequent incontinence as a result of partial cystectomy.
