[Management and complications of urinary diversions].

After cystectomy, the urine is eliminated by the uretra (orthotopic neobladder) or through a stoma. Orthotopic neobladder is done by priority when feasible. Practical aspects have to be managed very strictly by the urologist and the staff nurse. Side effects and complications are quite frequent (incontinence, retention, infection, diminished renal function, metabolic disorders, stoma complications) and need an adapted follow-up to propose adapted management if necessary.
