Endoscopic lithotripsy is first-line therapy for complicated upper urinary tract calculi and for patients who fail primary extracorporeal shock wave lithotripsy. A retrospective study conducted in urosurgical department in Emergency Medicine Institute from 2020 to 2022 aims to identify the need for use of laser lithotripsy and/or other ureteroscopic equipment in patient undergoing ureteroscopy for ureteric stone management. In the study was included 522 patients treated by ureteroscopy. The mean age of the patient was 43,4 years. Ureteroscopy had done in the right side in 273 patients, left side in 249 patients, and bilateral ureteroscopy in 16 patients. Ureteric stones found in upper ureter in 118 patients, middle ureteric stone seen in 57 patients, and lower ureteric stone founded in 347 patients, whereas 27 patients had stones at more than one location. Ureteric stone measuring 6 - 18 mm in largest diameter. Average duration of endoscopy was 23 minutes. A 92.7 % stone – free rate was obtained. No major complications occurred. Double J stent had been used in 98 patients and had been removed after 3 to 6 weeks. In conclusion ureteroscopy requires a good equipment, technical skills and vigilance of the performing urologist.
