Determing the success rate of extracorporeal shock wave lithotripsy in renal pelvis stone of 1-2 cm in size.

Abstract

Background: Despite its historical significance, ESWL has witnessed changes in its role, necessitating refined technical approaches and stringent patient selection criteria for optimal outcomes. This study aims to assess the efficacy of extracorporeal shock wave lithotripsy (ESWL) for treating renal pelvis stones ranging from one to two centimeters in size.
Methodology: A descriptive case series was conducted at the Department of Urology and Renal Transplantation, SIUT, Karachi. The study enrolled 81 patients aged 20 to 60, of both genders, with a single renal pelvis stone sized 1 2 cm. Patients with ureteral obstruction were excluded. Informed consent was obtained before performing extracorporeal shock wave lithotripsy (ESWL). Follow ups were carried out regularly, and final success was assessed one month post ESWL session.
Results: The mean age of participants was 41.93 ± 9.67 years, with the majority (54.32%) falling within the 41 to 60 age range. Out of 81 patients, 49 (60.49%) were male and 32 (39.51%) were female, resulting in a male-to-female ratio of 1.5:1. The mean stone size was 14.22 ± 2.01 mm. In the study, the success rate of ESWL for renal pelvis stones sized 1-2 cm was 85.19%, with 69 patients showing successful outcomes.
Conclusion: In conclusion, the success rate of ESWL for treating renal pelvis stones sized 1-2 cm is notably high. This finding underscores the effectiveness of this non-invasive procedure in managing such cases.
