The etiology for the development of colon carcinoma associated with ureterosigmoidostomy seems to be related to the urine. The incidence of colon carcinoma associated with ureterosignoidostomy is 500 times greater than in the normal population, indicating a 5 per cent lifetime risk. The development time of these lesions varies from 6 to 50 years postoperatively but development time is significantly less in patients more than 40 years old. The possibility exists that colon carcinoma may develop in primary sigmoid urinary diversion conduits or sigmoid internal conduits to either bladder or bowel. No reported bowel carcinoma has developed in an ileal urinary diversion. Follow-up evaluation should include stools for blood every 3 months after 2 years, excretory urogram yearly after 5 years, sigmoid or colonoscopy every 5 years and barium enema every 5 years. If the patient has hematochezia or the excretory urogram demonstrates ureteral obstruction sigmoid and colonoscopy should be done.

In a clinical and radiological study of seven neonates with bladder extrophy (BX), separation of pubic bones from the midline, lateral and caudal tilting of the iliac alae and external rotation of the acetabula, with consequent early predisposition to bilateral congenital hip dislocation (CHD), who were treated by a combined bilateral innominate osteotomy and reconstruction of the urinary bladder, there were only two failures due to CHD and three due to BX, which were dealt with at a later session. Although the bilateral transverse iliac osteotomy procedure is very rarely, if ever, employed in the neonatal period, it may well be combined with the reconstructive surgical procedures that involve pelvic skeletal structures while dealing with soft tissue procedures. Bilateral transverse iliac osteotomy was preferred to the conventional two-stage posterior iliac vertical osteotomies because of its easiness and the simple approach provided by the supine positioning of the patient.
The aim of secondary genital surgery in epispadias/exstrophy patients is to produce a dangling penis of satisfactory length and shape. The penis should be able to function sexually as well as serve as a conduit for the passage of urine and sperm. The systematic approach to the correction of this defect as outlined in this article should enhance the possibility of a successful result and lessen the need for secondary genital repair.
Skin grafting remains a primary modality for reconstruction of genitourinary defects. Many of these conditions are discussed and emphasis has been placed on the different indications for full-thickness, split-thickness, and dermal grafts. Complications have been few, and long-term results excellent. This experience has allowed the formulation of a number of surgical principles, which are presented. Refinements in reconstruction are currently being evaluated to obtain the optimal result.
Both clinical and experimental observations establish that an adenocarcinoma of the colon is likely to occur at the suture line of ureterosigmoidostomy. The carcinogenesis depends on the initial presence of urine, feces, urothelium, and colonic epithelium in close apposition at a healing suture line. It does not occur in isolated colon loops used for urinary diversion. In our rat model, tumors were completely prevented by interposing ileum between the urothelium and colon. Clinical prevention requires that accurate hospital registries of patients at risk be established and that repeated annual colonoscopy be carried out on all of them.
