title: [Complications and sequelae in the endoscopic follow-up of uretero-sigmoidostomies].
abstract: Progress in gastrointestinal endoscopy enables it to be used routinely in the diagnosis, treatment and follow-up of colonic tumours. The development of a tumour, especially adenocarcinoma, at the site of anastomosis of uretero-sigmoidostomy is a particular case. The endoscopic examination is delicate and confusion between the ureterocolonic junction and a polyp may have dramatic consequences when biopsy is performed. Two cases are reported: in one case, the error required nephro-ureterectomy and in the other case percutaneous nephrostomy, now a routine procedure, allowed salvage of the single kidney and preservation of the diversion with satisfactory long term function.
