    Abstract:
    PURPOSE: We evaluated long-term outcomes in patients undergoing augmentation enterocystoplasty (AC) (with or without an abdominal stoma) or continent urinary diversion in patients with benign urological disorders. MATERIALS AND METHODS: This was a retrospective study of 76 consecutive adults who underwent AC (with or without an abdominal stoma) or continent urinary diversion because of benign urological conditions. The outcomes assessed were a patient satisfaction questionnaire, continence status, catheterization status, bladder capacity, bladder compliance, detrusor instability, maximum detrusor pressure, upper tract status, significant postoperative morbidity, need for reoperation, persistent diarrhea and vitamin B12 deficiency. RESULTS: The 76 patients (18 men and 58 women) were 19 to 80 years old (mean age 49). Followup was 1 to 19 years (mean 8.9). Preoperative diagnoses were neurogenic bladder in 41 patients, refractory detrusor overactivity in 9, interstitial cystitis in 7, end stage bladder disease in 7, radiation cystitis in 3, exstrophy in 3, postoperative urethral obstruction in 3 and low bladder compliance in 3. A total of 50 patients underwent simple AC, 15 underwent AC with an abdominal stoma and 11 underwent continent supravesical diversion. Of the 71 evaluable patients 49 (69%) considered themselves cured, 14 (20%) considered themselves improved and 8 (11%) considered treatment to have failed. All 7 patients with interstitial cystitis had failed treatment. Mean bladder capacity increased from 166 to 572 ml and mean maximum detrusor pressure decreased from 53 to 14 cm H2O. Serum creatinine improved or remained normal in all patients. Five patients experienced persistent diarrhea requiring intermittent antispasmodics but none had vitamin B12 deficiency, pernicious anemia or malabsorption syndrome. Long-term complications were stomal stenosis or incontinence in 11 of 26 patients (42%) with stomas, de novo bladder and renal stones in 2 of 71 (3%) and 1 of 71 (1%), respectively, and recurrent bladder stones in 6%. Small bowel obstruction occurred in 5 of 71 patients (7%), requiring surgical exploration in 4 (6%). CONCLUSIONS: AC and urinary diversion provide a safe and effective long-term therapy in patients with refractory neurogenic bladder but stomal problems in patients with continent diversion continue to be a source of complications.
