A randomized controlled trial comparing infectious complications using mini perc with and without suction for renal stones less than 3  cm in size

AbstractThe purpose was to do a study to compare infectious complications in patients operated for MiniPerc or Minimally invasive Percutaneous Nephrolithotomy (MPCNL) using MIP and MPCNL with suction using Shah Superperc sheath for medium-sized renal stones less than 3  cm in size. The primary objective of this study is to compare the infectious complications and the secondary objectives are to compare stone-free rates, complication rates and operative times. A prospective randomized controlled trial with patients having proximal ureteral and renal stones of 10– 30 mm size and planned for MPCNL done at a single institute. A total of 80 consecutively admitted patients with written informed consent were included for randomization with 40 patients in each arm of MPCNL and suction MPCNL. The median age in MPCNL and suction MPCNL arms were 48 and 49 years, the median stone size of 15.45 and 16.7 cm, the Median stone volume of 1576.2 vs 1752 mm3, and the median stone density of 1258 and 1250  Hu, the median hospital stay of 3 days in both arms were comparable. Infectious complications were comparable in both arms. Operative time was significantly less in the suction MPCNL group (26.5 min–IQR 17–34.8) than in the MPCNL group (34.8 min–IQR 20–45),p = 0.021 and stone-free rates (SFR), were more in Suction MPCNL arm 97.5% than in MPCNL 87.5%,p = 0.04. Overall, the complication rates were comparable in both arms. Suction MPCNL procedure resulted in shorter ope...
