Objective: This study was conducted to evaluate the efficacy and safety of Miniperc (MIP) XS (7.5 Fr) nephroscope in the treatment of renal stones up to 20 mm. Methods: This was a prospective study that enrolled 65 patients with limited stone burden in calyx or pelvis, which were treated with MIP XS. Primary outcomes included stone-free rates (SFRs), operative time, length of postoperative hospital stay, requirement of analgesic postsurgery, decline in hematocrit, stent requirement, and complications and requirement of ancillary procedure. Results: The mean stone size was 17.46 ± 2.9 mm. The patients were treated with MIP XS and had a mean operative time of 38.63 ± 8.4 min, 1.74% drop in hematocrit levels postsurgery and 96.9% SFRs. The length of hospital stay was 55.48 ± 4.6 h. Postoperative fever and nephrostomy leakage occurred in 9 and 1 patients, respectively. Six cases required some drainage procedure (double-J stent/nephrostomy). No patient required blood transfusion. Conclusion: This study showed that MIP XS could be considered as an effective treatment option in the treatment of renal stones up to 20 mm as it scores in all the standard parameters used to measure percutaneous nephrolithotripsy outcomes.
