Abstract: Introduction: Minimally invasive procedures have almost completely replaced open surgery in patients with kidney stones over the past two decades1. Percutaneous nephrolithotomy (PCNL) is now the standard of care for the treatment of renal stones2. Miniaturized percutaneous Nephrolithotomy (PCNL) & Retrograde Intrarenal Surgery (RIRS) has become important alternative to standard PCNL for treatment of renal stones. Purpose of this study is to compare stone free rate, overall operative time, hospital stay and complication rate. Methods: Patients with single stone of size between 1-1.5 cm on non contrast CT-KUB were enrolled in this prospective randomised clinical study which was conducted from April 2021 to March 2022. Patients were randomised into two groups. Group 1: Mini PCNL - 30 patients Group 2: RIRS-30 patients. Results: In Mini PCNL group stone free rate was 86.7% (26/30). In RIRS group stone free rate was 76.7% (23/30). Haemorrhage in PCNL in 2 cases needing Blood transfusion. The overall stone free rate and complication rate for PCNL was higher. The operative time was more for RIRS than for Mini PCNL. Post operative hospital stay was longer in PCNL (4 days) than RIRS (2 days). Conclusion: Both mini-PCNL and RIRS have excellent outcomes for renal stones 1-1.5 cm in size. RIRS is close to mini-PCNL in terms of surgical duration, SFR, and repeated session and is an applicable alternative method due to advantages in terms of complications, duration of hospital stay, radiation exposure and blood loss.
