目的 探讨多层螺旋CT(MSCT) 尿道成像在尿道狭窄诊治中的应用价 值。方法 收集2015年1月-2018年6月就 诊于我院的前尿道狭窄患者65例，其中 30例行MSCT尿道造影检查(MSCT组)，35 例行传统X尿道造影检查(X线组)，两组 均行经尿道冷刀内切开术，对比两组诊 治情况。结果 两组术前尿道狭窄长度 测定结果与术中对比均无统计学差异 (P>0.05)。两组手术时间、术后住院时 间及术后最大尿流率(Qmax)、并发症发 生率对比均无统计学意义(P>0.05)，但 MSCT组中转开放手术比例明显低于X线组 (P<0.05)。MSCT组尿道狭窄或闭锁解剖 结构显示情况优于X线组。结论 MSCT尿道 成像能够清晰呈现尿道解剖结构，对尿 道狭窄的诊断及手术指导有重要价值。

Objective To investigate the application value of multi-slice spiral CT (MSCT) urethra imaging in the diagnosis and treatment of urethral stricture. Methods 65 patients with anterior urethral stricture who were diagnosed in the hospital from January 2015 to June 2018 were enrolled. Of them, 30 underwent MSCT urethrography (MSCT group), and 35 underwent traditional X-ray urethrography (X-ray group). Both groups underwent internal urethrotomy with cold knife. The diagnosis and treatment of the two groups was compared. Results There was no significant difference in the detected results of urethral stricture length in the two groups before and during surgery (P>0.05). There was no significant difference in the operation time, postoperative hospital stay, postoperative Qmax or incidence of complication between the two groups (P>0.05). However, the proportion of transferring to open surgery in the MSCT group was significantly lower than that in the X-ray group (P<0.05). The urethral stricture or display for atresia anatomy structure were better than those in than the X-ray group. Conclusion MSCT urethra imaging can clearly show the urethral anatomy structure, which is of great value in the diagnosis of urethral stricture and surgical guidance.
