Background: The present study evaluated the efficacy of extracorporeal shock wave lithotripsy (ESWL) in patients with mid- ureteric stones by analyzing the clearance rate. Materials and Methods:This prospective observational study was conducted in patients with mid ureteric stones at the Department of Urology, Indira Gandhi Institute of Medical Sciences, Patna,(2019-2021). Patients were divided into two groups according to stone size (mm); group A (up to 10 mm) and group B (11- 20 mm). Dornier Compact Delta II (Dornier MedTech Systems) was the ESWL lithotripter used to fragment ureteric stones. Results:A total of 34 patientsmean (SD) age of 33.7 (12.16) yearswere included in the study. The average clearance rate, irrespective of the stone size, was 88.23%,for midureteric stone. The ESWL was successful in group A (stone size <10 mm). In group B (stone size 11-20 mm), the ESWL faced more failure. The average retreatment rate was 38.21%.The most common complication was hematuria (8.02%), followed by transient colic and pyrexia (4.93%). Conclusion:ESWL is a safe, effective,non-invasive, and well tolerated treatment for the management of midureteric stones, regardless of the stone location. This study recommends that ESWL should be primary modality of treatment in patients with smaller mid ureteric stones up to 10 mm and with overall success rate of 88.23 irrespective of location and size, it is equally good option for stone size 10-20 mm.
