输尿管导管及锥形导丝在输尿管中上段碎石术中的临床应用

目的 探讨输尿管导管及锥形导丝在输尿管中上段碎石术中的临床应用效果。方法 选取于该院就诊的输尿管中上段结石患者150例，随机分为对照组（锥形导丝组）和观察组（输尿管导管组），每组各75例。比较两组患者的手术时间、住院天数、总费用、术中结石逃逸情况、术后血尿、发热、肾绞痛等并发症发生情况和术后1个月结石排净率。结果 两组患者手术时间和治疗费用比较，差异均有统计学意义；住院天数、术中结石逃逸情况、术后并发症发生率和术后1个月结石排净率比较，差异均无统计学意义。结论 应用锥形导丝及输尿管导管治疗输尿管中上段结石，治疗效果明确且并发症少。输尿管导管较锥形导丝手术时间长，但锥形导丝治疗费用相对较高。

Clinical study between the ureteral catheter and conical guide wire in treatment of ureteral middle and segment lithotripsy

Objective To investigate the clinical effect between the ureteral catheter and conical guide wire in treatment of ureteral middle and upper segment.Methods 150 patients were randomly divided into control group (n = 75) and observation group (n = 75). The operation time, length of hospital, hospitalization costs, migration of ureteral calculi, postoperative hematuria, fever, renal colic and the calculi clearance rates on one month after surgery were compared between the two groups.Results There were significant differences in operation time and hospitalization costs between the two groups. There were no significant differences in length of hospital stay, migration of ureteral calculi, postoperative complications rate and the calculi clearance rates on one month after surgery between the two groups.Conclusion Ureteral catheter and conical guide wire in treatment of ureteral middle and upper segment with definite therapeutic effect and the complication is few. The ureteral catheter has a longer operation time than conical guide wire, but the conical guide wire treatment cost is relatively high.
