Objective To compare the efficacy between ureteroscope with holmium laser lithotripsy (URS) and minimally invasive percutaneous nephrolithotomy (MPCNL) in oblique supine position for the proximal and middle ureteral calculi.Methods Ninety-six patients with proximal and middle ureteral calculi were divided into URS group (54 cases) and MPCNL group(42 cases) according to the treatment order.The operative duration,postoperative hospital stay,stone-free rate,intraoperative blood loss ＞ 400 ml rate,conversion to open surgery rate,complication rate including postoperative fever were observed,and stone composition was analyzed.Results The operative duration and postoperative hospital stay in URS group and MPCNL group were (55.3 ± 12.1),(49.6 ± 11.5) min and (1.7 ± 0.9),(4.4 ± 1.2) d,respectively,and there were significant differences (P ＜ 0.05 or ＜ 0.01).There were no significant differences in the stone-free rate,complication rate (Clavien degree Ⅱ),conversion to open surgery rate,intraoperative blood loss ＞ 400 ml rate,complication rate,postoperative fever rate (P ＞ 0.05).Stone composition analysis showed that the proportion of calcium oxalate stone was 51.0％(49/96).Conclusions URS and MPCNL in oblique supine position for the proximal and middle ureteral calculi are effective and safe therapeutic modalities.The operative duration of MPCNL in oblique supine position is shorter,and postoperative recovery of URS is fast.
