title: Gastrocystoplasty: an alternative solution to the problem of urological reconstruction in the severely compromised patient.
abstract: An isolated segment of stomach was used for bladder augmentation in 10 patients or construction of a continent urinary reservoir in 3. Diagnosis in these 13 patients included cloacal exstrophy (5), myelodysplasia (4), posterior urethral valves (2), radiation cystitis (1) and neurogenic bladder secondary to a rectal pull-through procedure (1). Indications for the use of stomach in bladder reconstruction were decreased renal function and acidosis (6 patients), insufficient large and small bowel (6) and decreased mucus production (1). Postoperative followup averaged 13 months (range 6 to 23 months). All patients have stable upper tracts radiographically and stable or improved renal function. Of 13 patients 10 require intermittent clean catheterization to empty and 11 are completely continent. Nine patients have remained free of infection, while 4 had asymptomatic bacteriuria. Mucus production is reduced relative to other intestinal segments and 10 patients require no bladder irrigations. Postoperative urodynamic evaluation is similar to that of ileocystoplasty or colocystoplasty. Use of stomach has protected these patients from the development of new or worsened hyperchloremic acidosis. Serum chloride values have decreased and serum total carbon dioxide values have increased after bladder reconstruction, particularly in patients with impaired renal function. Stomach should be considered when lower urinary tract reconstruction is necessary in such compromised patients.
