目的比较软镜与经皮肾镜在复杂性肾结石碎石术中的效果。方法研究对象为2011年3月—2013年6月就诊的复杂性肾结石患者70例,根据随机数字表法将患者分为A组、B组,各35例。A组给予软镜碎石术,B组给予经皮肾镜碎石术。两组均在术后2、30、90、180 d复查腹部平片、超声。对比两组手术时间、住院时间、结石排净时间、一次结石清除率、并发症发生率。计量资料采用t检验,计数资料采用χ2检验,P<0.05为差异有统计学意义。结果 A组手术时间、住院时间、结石排净时间[(57.91±11.60)min、(3.11±1.29)d、(4.21±3.09)周]与B组[(46.30±10.84)min、(4.96±1.67)d、(7.79±4.08)周]比较,差异均有统计学意义(均P<0.05)。A组一次结石清除率、并发症发生率(94.29%、11.43%)与B组(77.14%、65.71%)比较差异均有统计学意义(均P<0.05)。结论软镜碎石术治疗复杂性肾结石与经皮肾镜比较效果好,并发症少,可以在临床广泛推广。
Objective To compare the effect of soft lens and percutaneous nephrolithotomy in complex renal stone lithotripsy. Methods A total of 70 patients with complex renal calculi who were treated from March 2011 to June 2013 were enrolled in this study. Patients were divided into group A and group B according to the random number table. Group A was given soft-lens lithotripsy, Group B was given percutaneous nephrolithotripsy. Two groups were postoperative 2,30,90,180 d review of abdominal plain film, ultrasound. The operation time, hospitalization time, stone discharge time, primary stone removal rate and complication rate were compared between the two groups. Measurement data using t test, count data using χ2 test, P <0.05 for the difference was statistically significant. Results The operation time, hospitalization time, the time of stone discharge in group A [(57.91 ± 11.60) min, (3.11 ± 1.29) d, (4.21 ± 3.09) weeks] ) d, (7.79 ± 4.08) weeks], the differences were statistically significant (all P <0.05). In group A, the primary stone clearance rate, complication rate (94.29%, 11.43%) were significantly different from those in group B (77.14%, 65.71%) (all P <0.05). Conclusion Soft-mirror lithotripsy is more effective in treating complicated nephrolithiasis and percutaneous nephrolithotomy with less complications and can be widely used clinically.
