Urinary diversion, after cystectomy for bladder cancer or other bladder pathology, provides optimal storage and voiding capacity, preserving renal function properties, similar to bladder function, in appropriate patients. Decreased gastrointestinal absorptive capacity for special nutrition, vitamin and elements and excessive reabsorbtion of urinary waste product cause metabolic changes in patients with urinary diversion. These metabolic changes disturb acid-base balance, renal and hepatic function, and bone metabolism and sometimes these complications cause severe pathology causing to necessitate hospitalization. We presented short and long-term metabolic changes and complications of urinary diversions after radical cystectomy in this review. On the other hand, we mentioned about possible preventive strategies, and treatment options for these complications.
