软性输尿管镜(FURS)与经皮肾镜(PCNL)术式治疗肾结石的效果观察

Comparison of flexible ureteroscope(FURS)and percutaneous nephrolithotomy(PCNL) in the treatment of renal calculi

目的 比较分析软性输尿管镜(FURS)与经皮肾镜(PCNL)两种术式治疗直径≤2.0cm肾结石的临床效果。方法 将160例肾结石患者随机分为两组,各80例。对照组患者采用PCNL术式治疗,观察组患者采用FURS术式治疗。观察比较两组手术相关指标(手术时间、术中出血量、一期结石清除率、术后VAS疼痛评分、住院时间)、术后肾功能[血尿素氮(BUN)、血肌酐(Cr)水平]及并发症发生情况。结果 两组患者手术均顺利完成,观察组手术时间、术中出血量、术后VAS疼痛评分及住院时间均少于对照组,术后并发症发生率低于对照组,差异均有统计学意义(P<0.05或P<0.01);两组一期结石清除率及术后BUN、Cr水平比较,均无明显差异(P>0.05)。结论 FURS治疗直径≤2.0cm肾结石具有手术时间短、术中出血较少、术后疼痛较轻、术后并发症发生率较低等优势,值得临床推广应用。

Objective To explore the difference in FURS and PCNL in the treating renal calculus (diameter≤2.0 cm).Methods One hundred and sixty of renal calculi patients were randomly divided into control group and observation group,80 cases in each group.The control group was treated by PCNL and observation group was done by FURS.The operation time,intraoperative bleeding volume,stone clearance rate,visual analogue scale(VAS),hospitalization time,renal function(BUN and Cr)and the incidence of complication were compared between the two groups.Results The operation was successfully completed in both groups.The operation time,intraoperative bleeding volume,VAS score,hospitalization time and the incidence of complications in the observation group showed significantly lower than those of the control group( P <0.05 or P <0.01).There was no significant difference in the stone clearance rate and levels of BUN and Cr between the two groups( P >0.05).Conclusion Using FURS to treat renal calculi(diameter≤2.0 cm)can shorten operation time,decease postoperative pain,intraoperative bleeding,and the incidence of complications.
