“…The first case of malignant transformation complicating enterocystoplasty was reported in 1971 by Smith et al [3], who described a case of transitional cell carcinoma arising in the ileal segment of an ileocystoplasty in a 43-year-old woman, 17 years after the procedure. Since that time, 20 additional cases of malignancy complicating enterocystoplasty have been reported in the English literature [4][5][6][7][8][9][10]. Among these, adenocar-cinoma appears to be most common (n=14), followed in frequency by transitional cell carcinoma (n=3); sarcoma, not otherwise specified (n=l); small cell carcinoma (n= 1); and squamous cell carcinoma (n=l).…”

“…The development of malignancy in the setting of enterocystoplasty has been well documented, and, in most instances, these tumors are adenocarcinomas, but transitional cell carcinoma, squamous cell carcinoma, small cell carcinoma, and sarcoma have also been reported [3][4][5][6][7][8]. However, the long-term risks of neoplasia in the setting of gastrocystoplasty are not well known, and malignancy arising in this setting has not yet been reported.…”

Urinary bladder augmentation with segments of the stomach (gastrocystoplasty), small bowel, or large intestine (enterocystoplasty) improves capacity and compliance in patients with bladder dysfunction. Although malignant complications of enterocystoplasty have been reported, the risk of malignancy in the setting of gastrocystoplasty is not known. We describe the case of a 73-year-old woman who developed a transitional cell carcinoma associated with transitional cell metaplasia and dysplasia of the gastric epithelium 14 years following gastrocystoplasty. To our knowledge, this is the first reported case of a malignant complication of this surgical procedure. We conclude that patients who have undergone gastrocystoplasty are at an increased risk for the development of malignancy in the neobladder and require close long-term follow-up, similar to patients who have undergone enterocystoplasty.

“…Malignancy developing in enterocystoplasties has been reported in 31 patients to date; 20 ileocystoplasties [1–11], five colocystoplasties [12,13] and six caecocystoplasties [14–17]. Almost all were adenocarcinomas and occurred at or next to the suture line of the bowel and bladder.…”

Objective To establish the presence or absence of any diurnal or long-term variation in N-nitrosamine levels (which might be important in the development of cancer in enterocystoplasties) in enterocystoplasty urine, and to assess other factors that might alter enterocystoplasty N-nitrosamine levels. Patients, subjects and methods Thirty-six patients with enterocystoplasties and six normal controls were assessed. Urine samples were collected every 4 h over a 24-h period and N-nitrosamine levels determined using a modi®cation of the Pignatelli method. An additional urine sample was assessed by microscopy, culture and sensitivity. In a subgroup of 16 patients with an enterocystoplasty, the urinary N-nitrosamine levels were re-measured at 3-monthly intervals. Results No diurnal or long-term variation in urinary N-nitrosamine levels was identi®ed. The mean N-nitrosamine levels were signi®cantly higher in the cystoplasty group than in the controls (1.7 vs 1.0 mmol/L; P=0.008). Mean N-nitrosamine levels were also signi®cantly higher in enterocystoplasty patients with sterile pyuria than in those with no pyuria (P=0.01). Those taking prophylactic antibiotics had signi®cantly lower mean N-nitrosamine levels than those not doing so (P=0.05). Individuals with infected urine and those needing to intermittently catheterize had higher N-nitrosamine levels than their counterparts, but this difference was not signi®cant. Conclusion There were no diurnal or long-term variations in urinary N-nitrosamine levels. Levels were consistently higher in patients with in¯amed or infected cystoplasties, those using intermittent selfcatheterization and those not taking antibiotic prophylaxis.

Augmentation cystoplasty is performed in women for a variety of indications, including neurogenic bladder dysfunction, inflammatory diseases, small fibrosed bladders, idiopathic urge incontinence and enuresis. The preoperative evaluation, surgical techniques and postoperative management are reviewed. Complications of stone formation, urinary tract infections, mucus production, metabolic disturbances, hematuria and dysuria syndrome, tumors and perforations are addressed. In addition, alternative techniques such as ureterocystoplasty, autoaugmentation, seromuscular cystoplasty and the future of augmentation of the bladder utilizing techniques of tissue engineering are discussed. The management of pregnancy in women who have previously undergone augmentation cystoplasty is also reviewed.
