Abstract |
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.
