Kock pouch urinary diversion: follow-up by ultrasound.
In the post-operative follow-up of 24 patients who received a continent Kock pouch for urinary diversion, several complications were encountered, including hydronephrosis, stone formation and valve dysfunction, resulting in reflux and/or urinary incontinence. After comparing findings on ultrasound with those obtained by Koch pouch cystography, intravenous urography, plain abdominal radiography, Kock pouch endoscopy and operation, we consider ultrasound to be an important technique in the follow-up, especially in non-symptomatic patients. All cases of hydronephrosis and pouch calculi were detected by ultrasound and no false positive findings were encountered in either group. A good correlation is demonstrated between nipple length, as measured by ultrasound, and valve dysfunction, clinically important only for the afferent nipple.
