Abstract

Background: Complex kidney stones usually require multi-tract percutaneous nephrolithotomy (PCNL) to remove the stone completely. The aim of this study was to evaluate the clinical feasibility and safety of super multiple-tract (≥ 5 tracts) minimally invasive percutaneous nephrolithotomy (Mini-PCNL) in one stage for treating complex renal stones.

Methods: From March 2019 to August 2023, the perioperative clinical data of 35 patients who underwent super multiple-tract Mini-PCNL for complex kidney stones in our institution were collected and analyzed, retrospectively.

Results: A total of 35 patients were included in this study. The mean stone size and volume were 78.9 ± 22.8 mm and 13792.4 ± 5509.3 mm³, respectively. The mean S.T.O.N.E. score was 10.8, including 21 patients (60.0%) with scores ≥ 11. The average Guy's stone score was 3.5. The mean number of percutaneous tracts was 6.3 (range, 5-13). The average surgery time and length of hospital stay were 149.8 min and 3.4 days, respectively. The mean serum creatinine level declined by 6.5 mol/L (P = 0.518) and the mean hemoglobin drop was 24.9 g/L (P < 0.001). The postoperative complication rate was 25.7%, including one case of severe complication (Clavien grade IV). The mean follow-up time was 3.5 months, and the average glomerular filtration rate declined by 1.1 ± 8.7 ml/min (P = 0.463). The stone free rate was 82.9% after one- stage super multiple-tract Mini-PCNL.

Conclusion: When performed by experienced urologists, super multiple-tract Mini-PCNL for treating some complex renal stones in one stage is feasible and safe in enhancing the stone-free rate.

超级多道微创经皮肾镜取石术一期治疗复杂肾结石的初步经验。

背景：复杂肾结石通常需要多路经皮肾镜取石术（PCNL）才能完全取出结石。本研究旨在评价超多路（≥5路）微创经皮肾镜取石术（Mini-PCNL）一期治疗复杂肾结石的临床可行性和安全性。方法：回顾性分析我院2019年3月至2023年8月行超多路Mini-PCNL治疗复杂肾结石患者35例围手术期临床资料。结果：本研究共纳入35例患者。平均结石大小为78.9±22.8 mm，体积为13792.4±5509.3 mm3。S.T.O.N.E.平均评分为10.8分，其中21例（60.0%）评分≥11分。盖氏结石的平均评分为3.5分。平均经皮导管数6.3条（范围5-13条）。平均手术时间149.8 min，平均住院时间3.4 d。平均血清肌酐水平下降6.5 mol/L (P = 0.518)，平均血红蛋白下降24.9 g/L (P)。结论：在经验丰富的泌尿科医师的指导下，超多路Mini-PCNL治疗部分复杂肾结石一期有效，可提高结石的去除率。
