Background: A variety of treatment are available for ureteral calculi, including ureteroscopic lithotripsy, shock- wave lithotripsy, laparoscopic lithotomy, and percutaneous nephrolithotomy. Aim: Direct comparison of pneumatic and laser lithotripsy in the management of lower ureteric stone, in Ibn Sina hospital and Omdurman military hospital. Methods: This was analytic across-sectional hospital based multicenter study, conducted in Ibn Sina and Omdurman military hospital within the period from July up to December 2022. A hundred patients who presented with lower ureteric stone, during study period were included. Direct interviewing questionnaire was utilized. Results: The majority of patients (76%) had stone size between 11-15 mm and 24% with stone size between 7-10 mm. There was a higher proportion of stone free rate intraoperatively in uretroscope laser (90%) compared to uretroscope pneumatic (84%) however this was not statistically significant. The odds of stone free rate intraoperativewas increased by 1.7 folds in uretroscope laser management option (OR=.17; 95% CI (.5-5.6). Significantly less operation pain was found in uretroscope pneumatic 76% versus 92% in uretroscope laser. The probability of post- operative pain was reduced by 3.6 times (OR=3.6, 95% CI (1.1-12.2)) in uretroscope pneumatic. Also, significantly less post- operative fever was found in URS pneumatic 70% versus 88% in uretroscope laser. The risk of reduced post-operative fever in URS pneumatic was 3.1 folds (Or=3.1; 95% CI (1.1-8.9)). There was highly significant association between duration of operation and management options, p=.001 Less than one-hour duration time of operation was significantly achieved in URS pneumatic 80% versus 16% in URS laser management option. Conclusion: The study concluded that both URS laser and URS Pneumatic laser are effective and safe modalities in treating lower ureteric stones, URS pneumatic is superior in reducing complications in terms of pain and fever in addition to less duration time of operation (less than one hour), therefore it is recommended.
