title: [Papillary tumors of the upper urinary tract: endoscopic methods of diagnosis and treatment].
abstract: 53 patients (31 males and 22 females, age 16-82 years) suspected to have a papillary tumor of the upper urinary tract (UUT) underwent transurethral uretheronephroscopy (n = 49) and percutaneous nephroscopy (n = 4). Preoperative examination included clinical, x-ray, radionuclide, CT and cytological investigations. 11 patients with solitary papillary UUT tumors were studied endoscopically. Transurethral uretheronephroscopy and percutaneous nephroscopy detected UUT tumors in 31 (58.5%) patients. Postoperative period was uneventful. 3, 6, 12 months and later after endoscopic removal of UUT tumors a control examination was made (excretory urography, ultrasound examination, repeated rigid or fibrouretheroscopy, urinary cytological test). 2-8 years after endoscopic removal of the tumors 5 patients were free of the tumors, 5 patients withdrawn from the study. One woman with a recurrent tumor was reoperated endoscopically. The conclusion is that endoscopic methods are most precise and specific for diagnosis of papillary UUT tumors and should terminate preoperative examination to determine therapeutic policy. In indications for organ-saving therapy, endoscopic methods can serve as a method of choice in the treatment of the above patients.
