目的:探讨B超和X线定位经皮肾镜取石治疗上尿路结石的临床疗效比较。方法:回顾性分析2010年2月~2013年12月收治的300例上尿路结石患者的临床资料,根据定位方式分为X线定位组(164例)和B超定位组(146例),对两组患者围手术期临床数据进行比较。结果:X线定位组的穿刺时间为(10.3±4.2)min、手术时间为(103.5±27.5)min、穿刺中出血量为(45.8±9.8)ml、手术出血量为(96.7±34.8)ml、穿刺针数为(1.72±0.84)次,均显著的低于B超定位组(P<0.05);两组患者的住院时间差异无统计学意义(P>0.05)。术后X线定位组的感染率(8.54%)、术后继发出血(3.66%)、术后脏器损伤(0.00%)与B超定位组差异无统计学意义(P>0.05);但X线定位组的结石残余率7.93%显著低于B超定位组的15.07%。结论:X线定位经皮肾镜取石治疗上尿路结石较B超定位具有时间短、出血量少、术后结石残余率低等优势,值得临床推广应用。
Objective: To investigate the clinical effect of percutaneous nephrolithotomy with B-mode and X-ray in the treatment of upper urinary tract calculi. Methods: The clinical data of 300 patients with upper urinary tract calculi admitted from February 2010 to December 2013 were retrospectively analyzed. According to the location method, the patients were divided into X-ray group (164 cases) and B-ultrasound group (146 cases) Perioperative clinical data were compared between the two groups. Results The time of puncture was (10.3 ± 4.2) min, the time of operation was (103.5 ± 27.5) min, the amount of bleeding during puncture was (45.8 ± 9.8) ml and the amount of bleeding during operation was (96.7 ± 34.8) The number of puncture needles was (1.72 ± 0.84) times, both of which were significantly lower than those in the B-positioning group (P <0.05). There was no significant difference in hospitalization time between the two groups (P> 0.05). Postoperative X-ray group infection rate (8.54%), postoperative hemorrhage (3.66%), postoperative organ injury (0.00%) and B ultrasound group no significant difference (P> 0.05); The residual rate of calculus in X-ray group was significantly lower than that in B-ultrasound group (7.93% vs 15.07%). Conclusion: X-ray percutaneous nephrolithotomy lithotripsy treatment of upper urinary tract stones compared with B-positioning has a short time, less bleeding, postoperative residual rate of stones is low, worthy of clinical application.
