This chapter presents a glimpse on the conditions that may require urinary diversion. Urinary conduit is constructed most often after removal of the urinary bladder for invasive cancer. A well vascularised segment of intestine is necessary to fashion a urinary conduit which later on is to be connected to urinary tract to allow easy flow of urine through the abdominal wall through a stoma constructed exactly like an ileostomy. Urethral-vaginal confluence or cloaca in which there is also recto-vaginal fistula resulting in a single perineal opening leads to urinary incontinence requiring diversion.
