gastrins and Bacteriuria

The problems encountered with ileal and colocystoplasty have led to the use of the stomach for bladder augmentation, termed gastrocystoplasty. The advantages of gastrocystoplasty over intestinal segment augmentation include reduced chloride reabsorption, decreased mucus production, decreased urinary infection in the presence of acid urine, extremely low incidence of stones, and avoidance of complications from short bowel syndrome. The gastric patch provides comparable improvements in bladder volume, pressure, and continence. The thick muscular wall of the stomach facilitates ureteric reimplantation as compared with the small intestine, but the rate of stenosis and reflux may not be superior. The disadvantages of the gastric patch include complications of severe systemic alkalosis, which is usually manifest in dehydrated, renal compromised patients, and the hematuria-dysuria syndrome (HDS), which is more prevalent in patients with renal insufficiency, normal pelvic sensation, and urinary incontinence. The postoperative complication rate of gastrocystoplasty is comparable with that of other augmentation procedures and similarly warrants proper selection and close follow-up of patients. In this report we review the literature and present the results, including a discussion of the technique and the pathophysiology of its complications.
