This study aims to analyze the outcomes of morbidly obese patients who underwent ureterorenoscopy in the treatment of distal ureteral stones. Methods: The data of morbidly obese patients (>18 years of age) who underwent ureterorenoscopy for distal ureteral stones were examined retrospectively. Patients' demographic data, stone size, hydronephrosis degree, postoperative stent use, operation time, body mass index (BMI), hospital stay time, complication and stone-free rates were analyzed. Results: The study population included 29 morbidly obese patients (19 males and 10 females) with a mean age of 50.02±14.1 years. The average stone size was 28.58±8.55 mm. The mean operation time was 73.24±20.2 minutes, and the mean hospital stay was 1.65±1.14 days. We found the success rate to be 93.1%. Postoperative follow-up revealed urinary tract infection in one patient, and severe colic pain in two patients. Four patients had hematuria lasting less than 24 hours and requiring no blood transfusion. There was no major complication causing morbidity or mortality in any patient. Conclusion: Ureterorenoscopy is an effective treatment modality for the treatment of distal ureteral stones in patients with morbid obesity.
