title: [Colonic tumors after ureterosigmoidostomy. Value of coloscopy in their detection and treatment].
abstract: Congenital malformations and tumours of the bladder are the commonest indications of uretero-sigmoidostomy, an operation associated with the name of Coffey who perfected the technique. A part from the renal and metabolic complications of this operation, the risk of benign or malignant tumours at the anastamosis should not be overlooked. Four cases are reported which underline the incidence of juvenile polyps and mixed juvenile and adenomatous polyps which tend to degenerate. The medical literature is reviewed. Uretero-sigmoidostomy is a definite cause of tumour formation. The different pathogenic hypotheses are discussed. Colonoscopy is a method of detecting the tumour, of obtaining a histological diagnosis and treating benign polyps by diathermy under endoscopic control. This technique allows preservation of the anastomosis. The prevention of these lesions should be assured by annual endoscopy for 5 years after operation.
