Abstract:
【Objective】 To investigate the efficacy and safety of double-sheath vacuum suction microchannel percutaneous nephrolithotomy (MPCNL) in the treatment of complex renal stones. 【Methods】 The clinical data of 139 patients with complicated renal stones who received MPCNL during Aug. 2019 and Jul.2020 were retrospectively analyzed. According to the operation modes, the patients were divided into the double-sheath vacuum suction group (dsVS group, n=72) and conventional nephrostomy sheath group (cNS group, n=67). The perioperative indexes and the first-stage stone clearance rate of the two groups were compared. 【Results】 In the dsVS group and cNS group, the mean operation time was (46.72±9.55) min and (57.22±11.31) min, respectively (P<0.05). The first-stage stone clearance rate was 83.33% and 70.15%, respectively (P<0.05). The BUN value was (5.07±1.65) mmol/L and (5.75±1.83) mmol/L, respectively (P<0.05). The WBC value was (9.45±2.46)×109/L and (10.71±3.14)×109/L, respectively (P<0.05). The incidence of postoperative fever was 1.39% and 11.94%, respectively (P<0.05). There was no significant difference in other clinical data between the two groups (P>0.05). 【Conclusion】 The double-sheath vacuum suction MPCNL is safe and effective to manage complex renal stones, which can shorten the operation time, reduce postoperative complications, and improve the stone clearance rate.
