目的:探讨可视穿刺经皮肾镜取石术(micropercutaneous nephrolithotomy,Microperc)治疗鹿角形结石术后残留结石的安全性及有效性。方法:自2015~2016年,采用可视穿刺经皮肾镜取石术治疗鹿角形结石术后残石16例(Microperc组),采用微创经皮肾镜取石术治疗鹿角形肾结石术后残石12例(mPCNL组),收集两组患者的年龄、残石数目、结石负荷、手术时间、通道数目、清石率、并发症发生率、术后疼痛评分、住院天数进行统计学分析。结果:Microperc组结石清石率高于mPCNL组(87.50%vs.50.00%,P<0.05),术后疼痛评分较mPCNL组为轻[(2.62±2.24)vs.(5.04±3.42),P<0.05],住院时间短于mPCNL组[(3.46±3.03)d vs.(6.88±4.91)d,P<0.05],手术时间长于mPCNL组[(93.75±12.80)min vs.(52.25±8.53)min,P<0.05],术后并发症发生率两组差异无统计学意义(P>0.05)。结论:Microperc治疗鹿角形结石术后残石安全、有效,可提高残石的清石率,缩短住院时间。
Objective: To investigate the safety and efficacy of micropercutaneous nephrolithotomy (Microperc) in the treatment of residual stones after antaglossal operation. Methods: From 2015 to 2016, 16 cases of deer staghorn stone were treated by visible puncture and percutaneous nephrolithotomy (Microperc group), and minimally invasive percutaneous nephrolithotomy was used to treat staghorn kidney stones Stone 12 cases (mPCNL group) were collected, the age, residual stone number, stone load, operation time, number of channels, clear stone rate, complication rate, postoperative pain score and hospitalization days were collected for statistical analysis. Results: Compared with mPCNL group, the percentage of clear stones in Microperc group was significantly higher than that of mPCNL group (87.50% vs. 50.00%, P <0.05), and postoperative pain score was lighter than that in mPCNL group (2.62 ± 2.24 vs. 5.04 ± 3.42, P < 0.05]. The length of stay in hospital was shorter than that in mPCNL group [(3.46 ± 3.03) d vs. (6.88 ± 4.91) d, P <0.05], and the operative time was longer than that in mPCNL group [(93.75 ± 12.80) min vs. (52.25 ± 8.53) min , P <0.05]. There was no significant difference in the incidence of postoperative complications between the two groups (P> 0.05). Conclusion: Microperc is safe and effective in treating staghorn stone after antler operation, which can increase the rate of stone removal and shorten the hospitalization time.
