The principal methods of urinary diversion entail fashioning a segment of intestine into a conduit or reservoir to which the ureters are anastomosed. Methods of urinary diversion are commonly differentiated according to whether the functional result is urinary incontinence or continence: either incontinent cutaneous diversion or continent diversion may be performed, with the latter method involving either orthotopic bladder replacement with attachment to the intact native urethra or creation of a reservoir with cutaneous diversion.MRU is an accurate method for evaluating patients with cancer bladder that underwent radical cystectomy & urinary diversion, especially with patients with renal impairment & repeated short term follow up. Comprehensive MRI study including conventional sequences and MRU are useful for achieving an accurate and prompt diagnosis of complications and obtaining information that is essential or adequate surgical management.Early complications (complications that occur less than 30 days after surgery) include alterations of bowel motility, small-bowel obstruction, urinary leaks, collections, infections, and fistulas. Late complications of urinary diversion (complications that occur 1 month or more after surgery) include urinary tract infection, ureteral stenosis, herniation, lithiasis, and tumor recurrence.In our study, the aim was to evaluate those patients whether symptomatic or asymptomatic for detection of post-operative complications.
