经尿道Peel-away鞘输尿管镜与经尿道输尿管镜治疗膀胱结石的疗效比较

Efficacy between ureteroscopic via urethral Peel-away sheath and transurethral ureteroscopy in treating bladder calculi: A comparative study

目的比较经尿道Peel-away鞘输尿管镜与经尿道输尿管镜治疗膀胱结石的效果。方法将该科2013年1月-2015年12月76例膀胱结石按随机原则分为:A组(经尿道Peel-away鞘输尿管镜膀胱碎石术)45例;B组(经尿道输尿管镜膀胱碎石术)31例。结果 76例膀胱结石均获一次性碎石取石成功。碎石时间:A组(17.8±5.9)min,B组(22.7±8.3)min,差异有统计学意义(t=2.96,P=0.004);清石时间:A组(12.6±4.9)min,B组(24.5±5.3)min,差异有统计学意义(t=9.90,P=0.000);术中尿道黏膜损伤:A组(1.0±0.5)分,B组(2.1±0.4)分,差异有统计学意义(t=9.47,P=0.000);VAS评分:A组(1.9±0.6)分,B组(2.6±0.6)分,差异有统计学意义(t=4.72,P=0.000);留置导尿管时间:A组(1.0±0.2)d,B组(1.4±0.9)d,差异有统计学意义(t=2.59,P=0.012);住院费用:A组(7 437.4±356.7)元,B组(7 296.8±333.8)元,差异无统计学意义(t=-1.73,P=0.087)。两组术中无膀胱大出血、穿孔和破裂等并发症,无中转开放手术。术后并发症:B组发生术后泌尿系感染1例,经口服抗生素治疗后痊愈;A组发生术后尿潴留1例,B组5例,差异有统计学意义(χ2=6.43,P=0.011)。随访情况:失访13例,余63例随访6~12个月,两组各有1例老年男性患者因前列腺增生导致尿潴留;余患者均无再发结石,无尿道狭窄。通过统计分析结果,发现A组在碎石时间、清石时间、尿道黏膜损伤、术后疼痛和术后留置导尿管时间等方面较B组具有明显优势。结论经尿道Peel-away鞘输尿管镜与经尿道输尿管镜治疗膀胱结石疗效无明显差异。经尿道Peel-away鞘输尿管镜在碎石时间、清石时间及避免术中损伤尿道黏膜方面更优,两组手术费用无明显差异。经尿道Peel-away鞘输尿管镜是一种值得推广的内镜膀胱碎石手术方法。

Objective To compare the effectiveness of ureteroscopic via urethral Peel-away sheath and transurethral ureteroscopy in treatment of bladder calculi.Methods Clinical data of76cases of bladder calculi patients were collected from January2013to December2015.All the patients were randomly divided into two groups:Group A was performed by ureteroscopic lithotripsy via urethral Peel-away sheath(n=45).Group B wastransurethral ureteroscopic lithotripsy(n=31).Results76cases of bladder calculi were successfully treated by one-time lithotripsy.Lithotripsy time:group A was(17.8±5.9)min,group B was(22.7±8.3)min(t=2.96,P=0.004);stone clearance time:group A(12.6±4.9)min,group B(24.5±5.3)min(t=9.90,P=0.000);Intraoperative urethral mucosa injury:group A(1.0±0.5),group B(2.1±0.4)(t=9.47,P=0.000);VAS score:group A(1.9±0.6),group B(2.6±0.6)points(t=4.72,P=0.000);indwelling catheter time:group A(1.0±0.2)d,B group(1.4±0.9)d(t=2.59,P=0.012);There was no significant difference in hospitalization expense,group A was(7437.4±356.7),group B was(7296.8±333.8)(t=-1.73,P=0.087).There were no complications such as hemorrhage,perforation and rupture of the2groups,without convertion to open surgery either.After the treatment of oral antibiotic,1case of postoperative urinary tract infection was cured in group B.In our study,case of postoperative urinary retention was1in group A,versus5in group B,with statistical difference(χ2=6.43,P=0.011).Follow up:13patients were lost to follow-up,the other patients were followed up for6~12months.There was1case of elderly male patient with urinary retention due to BPH in each of the2groups,the other patients had no recurrence of calculus.By analyzing the statistical results,it was found that the experimental group had obvious advantages over the control group in the lithotripsy time,stone clearance time,urethral mucosa injury,postoperative pain and postoperative indwelling catheter time.Conclusion There is no significant difference in efficacy of the treatment of bladder calculi between ureteroscopic via urethral Peel-away sheath and transurethral ureteroscopy.However,our study shows the Peel-away ureteroscopy has the advantages of shorter lithotripsy time,shorter time of stone clearance and less injury of urethra mucosa menbrane,there was no significant difference in operation cost between two groups.Therefore,Ureteroscopic via urethral Peel-away sheath is an effective method for endoscopic bladder lithotripsy.
