[Endourologic treatment of tumors and pseudotumors of the upper excretory system].
Thirteen patients with a benign tumor or pseudotumor of the upper urinary tract underwent endourological treatment on 17 occasions. These patients were divided into two groups according to the anatomopathological findings. Five patients comprised group I. Mean patient age, 57.3 years. These patients had a tumor in the excretory cavity. Endoscopic work up revealed 3 papillary necroses, 1 inflammatory polyp, 1 Von Brun islet. One ureterorenoscopy (biopsy + laser) and four percutaneous (tumor resection) procedures were performed. Eight patients comprised group II. Mean patient age, 59 years. Six patients had pyelocaliceal tumors and two patients had ureteric tumors. Histologic analyses revealed a noninvasive low grade tumor on six occasions and two fibroepithelial polyps. Two ureteric tumors and 1 pelvic tumor were treated by retrograde ureterorenoscopy (2 resections and 1 Nd/Yag laser photocoagulation). Five patients were treated percutaneously (resection alone or combined with Nd/Yag laser). Four patients received local chemotherapy. Patient follow-up ranged from 1 to 3 years. Tumor recurrence was observed in 3 patients treated by percutaneous resection.
