Prospective comparative study of Miniperc and standard PNL for treatment of 1 to 2 cm size renal stone

OBJECTIVE • To evaluate the results of miniperc vis-a-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
