目的:比较与评价我院改良创新的后腹腔镜输尿管支架管留置方法与目前常用的留置方法的临床效果。方法:回顾性分析我院改良创新留置方法、目前常用留置方法应用于24例患者的资料。 结果:我院改良创新留置方法18例,目前常用留置方法6例。全部病例留置输尿管支架管均成功。我院改良创新留置方法平均留置时间2 min,目前常用留置方法平均留置时间6 min。结论: 我院改良创新留置方法为后腹腔镜输尿管支架管的留置提供了一种新的选择,且操作便捷、易于掌握和适宜推广。
ObjectiveTo investigate the necessity of indwelling ureteral stent before flexible ureteroscopic lithotripsy in the treatment of upper urinary tract calculi. MethodsEighty-five patients with upper urinary tract calculi treated between June 2013 and December 2014 were divided into two groups:group A (without indwelling stent, n=42) and group B (with indwelling stent, n=43).Incidence of stent-related urinary tract symptoms, operation time, one-time success rate of placement for ureteral access sheath, and stone clearance rate were compared between the two groups. ResultsThe operation time and stone clearance rate had no statistically significant differences between the two groups (P > 0.05).The incidence of stent-related urinary tract symptoms and one-time success rate of placement for ureteral access sheath in group B were significantly better than those in group A (P < 0.05). ConclusionFor one-phase operation success, we suggest that indwelling ureteral stent is necessary before flexible ureteroscopyic lithotripsy for treating upper urinary tract calculi.
