ABSTRACT

Introduction: Ureteroscopy is at present, one of the main treatment options for renal and ureteral lithiasis.
Objective: To describe the results of the treatment, by rigid retrograde ureteroscopy, in a series of patients with upper urinary tract lithiasis.
Methods: observational, descriptive, longitudinal and prospective study, in a sample of 53 patients with renal or ureteral lithiasis, who received treatment by rigid retrograde ureteroscopy. The variables studied were: age, sex, location of lithiasis, lithotripsy modality performed, complementary techniques used and complications presented. The results were analyzed by descriptive statistics.
Results: Patients of the sixth decade of life predominated. The average age was 50.2 years with predominance of males, with 36 patients, for 67.9%. The predominant lithiasis was the ureteral with 67.9%, and most located in its distal portion with a size between 10 and 20 mm. The most used lithotripsy modality was pneumatic in 46 patients (86.8%). The most used complementary technique was lithofragmentation (96.2%). There were complications in 8 patients (15%), and all in grades II and III of the Clavien-Dindo classification.
Conclusions: Rigid retrograde ureteroscopy, complemented with other endourological procedures, constitutes an effective and safe therapeutic modality for the treatment of renoureteral lithiasis, and with a low rate of complications.
