Augmented bladders and urinary diversions

Bone and metabolic complications of urinary diversions.

Hyperchloremic metabolic acidosis is a complication of urinary diversion using ileum or colon. Its prevalence ranges from 25% and 46% depending on the procedure used and renal function of the patient. It is a consequence of intestinal fluid and electrolyte exchange between intestinal mucosa and urine. The main mechanism is absorption of ammonium and chloride from urine. Long-term chronic metabo...

Continent Urinary Diversions in Non Oncologic Situations: Alternatives and Complications

Urinary diversion is a detour of the urinary tract. It may be necessary in different scenarios and can either be continent or incontinent, catheterisable or orthotopic.

Management of urolithiasis in patients after urinary diversions.

After urinary diversion patients are at increased risk of long-term complications, including stones of the upper urinary tract and reservoir or conduit. Advances in instrumentation and techniques have expanded treatment options, while minimizing morbidity. Minimally invasive treatment methods include shockwave lithotripsy, antegrade and retrograde ureteroscopic lithotripsy and percutaneous neph...

Urinary diversions after cystectomy: the association of clinical factors, complications and functional results of four different diversions.

PURPOSE We present a single institute experience of the four most widely used diversions after cystectomy in 281 patients, with an evaluation of the association between clinical factors, complication rates, functional results, and metabolic complications. MATERIALS AND METHODS Between 1990 and 2005, 281 consecutive cystectomies were performed at our institute. Four different diversions were o...
