An ileal conduit (or " Bricker conduit ") was one of the original types of urinary diversions, and it is still in use today. The conduit is most often placed after cystectomy (or cystoprostatectomy) for muscle-invasive bladder cancer.

Ureteroenteric anastomotic (UEA) stricture remains a significant complication after continent or incontinent urinary diversion. On CT, intraperitoneal urinary leak from ileal conduit or neobladder may be detected as extravasation of contrast material into the peritoneal space. Late complications include ureteroileal anastomotic stricture, stomal stenosis, conduit stenosis, and urolithiasis. Radiographics. KEYWORDS. Radiographic features. The most frequent conduit related complications observed 3 months after sur-gery are summarized in figure 2.

The most commonly reported complications in ileal conduit are: prolonged ileus, stoma infection, wound dehiscence and bacterial colonization, followed by peristomal skin complications and complications related only to the stoma, such as stenosis and stoma retraction, and prolaps of ileostoma and ile … An injury or trauma external or internal when become severe also require ileal conduit after the removal of urinary bladder. There may be a defective urinary bladder by birth which causes problem in excreting the urine and as result the physician recommend the patient to remove urinary bladder by making a new connection named ileal conduit. Stomal stenosis, or narrowing of the distal aspect of the conduit near its outlet with the skin surface, may be best appreciated with a loopogram study of the conduit.
