Urinary diversion is created after the removal of the urinary bladder (radical cystectomy or cystoprostatectomy, usually done to treat invasive bladder cancer).
There are three main varieties:
- neobladder formed from a segment of ileum (i.e. ileal conduit, also known as a "Bricker conduit")
- the segment of ileum extends to an ostomy on the abdominal wall
- neobladder reservoir formed from bowel with cutaneous diversion, e.g.
- "orthotopic" neobladder
- e.g. Studer pouch, T-pouch neobladder, W-reservoir, Kock ileal pouch
- an isoperistaltic, tubular segment of ileum is formed into a pouch
- the outlet is the native urethra
The types of urinary diversion with a reservoir or neobladder are considered "continent" types of urinary diversion.
The imaging appearance depends on the type of neobladder formed.
Methods of radiological assessment include all modalities, with a unique fluoroscopic study being a loopogram via the conduit stoma.
