Introduction

To do a study to compare infectious complications in patients operated for MiniPerc or Minimally invasive Percutaneous Nephrolithotomy (MPCNL) using Storz MIP system without suction 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 was to compare the infectious complications and the secondary objectives were to compare stone free rates, complication rates and operative times

Materials

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. 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.

Results

,

Median age in MPCNL and suction MPCNL arms were 48 and 49 years, median stone sizes were 15.45 and 16.7 cm, Median stone volume were 1576.2 vs 1752 mm³, and median stone density was 1258 and 1250 Hu respectively, median hospital stay of 3 days in both arms were comparable. Infectious complications were comparable in both the arms. Operative time was significantly less in the suction MPCNL group (26.5 min, IQR 17-34.8) than in MPCNL group (34.8 min, IQR 20-45), p=0.021 and Stone free rates were more in Suction MPCNL arm at 97.5% than in MPCNL at 87.5%, p=0.04. Overall, the complication rates were comparable in both the arms.

Conclusion

Suction MPCNL procedure resulted in shorter operating times and more stone free rates than conventional MPCNL with comparable complication rates.
