We aim to assess the efficacy and safety of MPNL for the treatment of 10-30 mm renal calculi. METHODS: A registered RCT (ID: NCT04153461) was conducted for patients having renal calculi with 10-30mm in their largest diameter. Patients were randomized to MPNL (15 F) with laser dusting and SPNL (30 F) with pneumatic and/or ultrasonic stone disintegration. The primary outcome was the immediate stone free rate (SFR) assessed by non contrast spiral CT (NCCT). Stone free was defined as no stone or stone <4mm in its maximum diameter. The secondary outcomes included operative time, post-operative complications as defined by the Clavien-Dindo grading system, post-operative pain using visual analog scale (VAS) , patient satisfaction using Freiburg index of patient satisfaction (FIPS) and hemoglobin drop. RESULTS: The baseline demographic data of the patients and stone characteristics were comparable in both groups. Immediate SFR was 90.2% in MPNL and 96.2% in SPNL (p=0.08). Post-operative complications did not show a significant difference between groups (p=0.2). Postoperative pain was 3.4 ± 1.2 and 4.9 ± 1.6 in MPNL and SPNL, respectively (p<0.001). (Table 1). CONCLUSIONS: For patients with renal stone 10-30 mm, MPNL is as effective and safe as SPNL with less bleeding and postoperative pain and high patient satisfaction but longer operative time.
