Background: Urolithiasis has affected humans since antiquity. The aim of the study was to evaluate the efficacy and outcome of retroperitoneal laproscopic pyelolithotomy and open pyelolithotomy in patients with renal stones.

Methods: The present prospective randomized clinical study was carried out in department of surgery from June 2017 to April 2021 in patients with renal stones. A total of 100 patients with solitary renal pelvic stone were properly assessed radiologically and clinically before planning the surgical intervention.

Results: The overall mean age of presentation among patients undergoing pyelolithotomy was 41.9±12.30 years (χ2=5.14, p≤0.001). Minimum number of patients were 41-60 years age group i.e.; 58 patients. 70 patients were males while 30 patients were females with male to female ratio 2.33:1. The mean stone size among patients undergoing LP and OP was 1.9±0.5 cm. The mean operative time (min) among patients undergoing LP group (123.9±9.5 minutes) was more as compared to OP group was 80.1±17.5 min. The mean duration of return to work was 3.86±1.39 days. The mean duration of return to work in LP group was 3.87±1.37 days, while in OP group was 5.87±1.34 days (χ2=18.56, p<0.02).

Conclusions: Retroperitoneal laproscopic pyelolithotomy proved to be safer in all the aspects than open pyelolithotomy.
