    Abstract:
    OBJECTIVE: To compare the morbidity of different types of permanent urinary diversion. METHODS: We reviewed the postoperative and longterm complications observed in 85 patients who underwent permanent urinary diversion from December, 1986 to January, 1993: cutaneous ureterostomy (16 pts.), transintestinal incontinent cutaneous ureterostomy (41 pts.), orthotopic neobladder (27 pts.). All patients underwent radical cystectomy for bladder carcinoma. The surgical technique utilized for the construction of the orthotopic neobladders were as follows: Camey 1 (4 cases), Camey II (6 cases), Mainz (2 cases), Hautman (6 cases), detubularized sigmoid (6 cases). We also reviewed and used for comparison 18 augmentation cystoplasties that underwent simple subtotal cystectomy. Augmentation cystoplasty was performed with the sigmoid (n = 8), ileon (n = 5) and ileocecal segment (n = 4). RESULTS: The incidence of postoperative complications was similar for all types of urinary diversion (64.3% for cutaneous ureterostomy, 61% for transintestinal intermittent cutaneous ureterostomy, 59.3% for orthotopic neobladder), although patients with orthotopic neobladders required surgery more frequently (7.1% for cutaneous ureterostomy, 22% for transintestinal cutaneous ureterostomy, 41% for orthotopic neobladder). The incidence of postoperative complications was much lower in patients who underwent augmentation cystoplasty (complications 17.7%; none required surgery). The percentage of longterm complications was 71.4% for cutaneous ureterostomy, 74.2% for cutaneous transintestinal ureterostomy, 86.9% for orthotopic neobladders and 100% for augmentation cystoplasties. The patients who required surgery were 14.3%, 19.3%, 26% and 47%, respectively. Twelve out of 24 patients in whom metalic staples were employed for the construction of the neobladders and cystoplasties developed bladder stones; 78.3% of the patients with orthotopic neobladders showed perfect daytime continence, 65.2% night-time incontinence and 21.7% stress incontinence. The figures for augmentation cystoplasties were 94.1%, 5.9% and 5.9%; 4.3% of patients with orthotopic neobladders and 29.4% of patients with augmentation cystoplasties required self intermittent catheterization. Patients with larger neobladders showed best continence rates. Fifty-three ureters were reimplanted in the orthotopic neobladders of augmentation cystoplasties with the Le Duc technique; 17% developed ureteral stenosis and 15.1% vesicoureteral reflux. CONCLUSION: Patients who undergo permanent urinary diversion have a far from negligible number of postoperative and long-term complications. Orthotopic intestinal neobladders have a slightly higher rate of serious complications than incontinent cutaneous diversions.
