Background: The present study was conducted to assess efficacy of surgical techniques and factors affecting residual stone rate in the treatment of kidney stones. Materials & Methods: 102 patients of kidney stones of both genders were divided into 3 groups. Group I patients underwent open stone surgery, group II patients underwent percutaneous nephrolithotomy (PNL) and group III underwent retrograde intrarenal surgery (RIRS). Surgical techniques complications were evaluated. Results: In group I mean stone burden was 3.2 cm2, in group II was 2.5 cm2 and in group III was 1.9 cm2. The mean operative time in group I was 84.2 minutes, in group II was 118.4 minutes and in group III was 78.6 minutes. There were 9 cases in group I, 7 in group II and group III was 5 cases. There were 7 cases of fever in group I, 4 in group II and 2 in group III, infection 2 in group I and 3 in group III, urine leakage 5 in group III and persistent pain 6 in group I and 1 in group II. The difference was significant (P< 0.05). Conclusion: PNL and RIRS have been seen as safe and effective methods as compared to open method in case of kidney stones.
