Clinical value of complete lateral position endoscopic combined intra-renal surgery in treatment of staghorn kidney calculi / 中国医师进修杂志

ABSTRACT

Objective:To assess the safety and feasibility of complete lateral position endoscopic combined intra-renal surgery (ECIRS) in treatment of staghorn kidney calculi.Methods:The clinical data of 105 patients with staghorn kidney calculi from March 2016 to July 2022 in the First Hospital of Shanxi Medical University were retrospectively analyzed. Among them, 55 patients were treated with lateral position percutaneous nephrolithotomy (PCNL) (PCNL group), and 50 patients were treated with complete lateral position ECIRS (ECIRS group). The operative time, removal time of double J-tube, postoperative hospital stay, postoperative hemoglobin decrease value, operative complications (using Clavien-Dindo grading criteria), additional postoperative intervention and calculi free rate were compared between two groups.Results:Both groups of patients were successfully operated. The operative time, postoperative hemoglobin decrease value and rate of additional postoperative intervention in ECIRS group were significantly lower than those in PCNL group (98.3 ± 19.1) min vs. (103.4 ± 16.5) min, (9.34 ± 3.04) g/L vs. (12.55 ± 4.75) g/L and 8.00% (4/50) vs. 21.82% (12/55), the calculi free rate was significantly higher than that in PCNL group 90.00% (45/50) vs. 74.55% (41/55), and there were no statistical differences ( P<0.05 or <0.01); there were no statistical differences in the removal time of double J-tube, postoperative hospital stay, incidence of Clavien-Dindo≥ grade Ⅱ operative complications between two groups ( P>0.05). Conclusion:The complete lateral position ECIRS is a safe and effective treatment for staghorn kidney calculi, and is a good complement to the ECIRS technique because of its high stone free rate in phase Ⅰ, low complication incidence and easy dissemination.
