Radiographic evaluation of the urethral Kock ileal bladder substitute

Abstract

Fifty male patients who had undergone bladder substitution with a urethral Kock pouch after radical cystectomy for bladder cancer, were evaluated in the immediate postoperative period by retrograde pyelography and pouch cystography, and at later follow-up by pouch cystography. Other radiologic procedures (urography, ultrasonography, CT, etc.) were not part of a routine program, but were used when clinically indicated. In 12% a ureteroileal anastomotic leakage was found; the leaks resolved with continued ureteral stenting. Extravasation at the anastomosis between the pouch and the urethra was seen in 55% at the first cystography. It resolved within one month in all cases by simply leaving a catheter in the bladder. On the late cystograms reflux was observed in 6% of patients, whereas stone formation in the pouch was not encountered. A careful radiologic follow-up of patients with urinary diversions is essential to minimize postoperative complications.
