Study Type - Therapy (case series) Level of Evidence 4 OBJECTIVE: • To evaluate the results of miniperc vis-à-vis standard PNL in the treatment of stones of 1-2 cm in size. Miniperc may represent a reasonable procedure in patients with nonbulky urolithiasis offering a similar outcome as standard percutaneous nephrolithotomy (PNL) with advantage of reduced morbidity. PATIENTS AND METHODS: • 55 procedures including 27 miniperc and 28 standard PNL were performed for renal stones 1-2 cm in size. Pediatric patient, active urinary tract infection, renal malformation, uncorrected coagulopathy and morbid obesity patients were excluded from the study. • The parameters studied were demography, operative time, postoperative analgesic requirement, hemoglobin drop, complications and stone clearance. RESULTS: • Mean tract size was 18.2 ± 2 F (15-20) and 26.8 ± 2 F (24-30), P value <0.0001 in the miniperc and standard PNL, respectively. Holmium LASER and pneumatic lithotripter were the main energy sources used in miniperc and standard PNL, respectively. • Miniperc operative time was longer than that of standard PNL (45.2 ± 12.6 vs 31 ± 16.6 min, P= 0.0008 respectively). • Conversely, there was an advantage of miniperc over standard PNL in terms of a significantly reduced hemoglobin drop (0.8 ± 0.9 vs 1.3 ± 0.4 gram%, P= 0.01), analgesic requirement (55.4 ± 50 vs 70.2 ± 52 mg tramadol, P= 0.29) and hospital stay (3.2 ± 0.8 vs 4.8 ± 0.6 days, P≤ 0.001), respectively. • Intra- operative conversion of the procedure into a tubeless PNL was significantly more in the miniperc group (P≤ 0.001). The miniperc and standard PNL group had clearance rates of 96% and 100%, respectively at 1 month follow up. CONCLUSIONS: • This study demonstrated significant advantages of the miniperc procedure in terms of reduced bleeding leading to a tubeless procedure and reduced hospital stay. • The stone free rates and the complications were similar in either group.
