尿道带管造影的临床应用价值

目的 探讨尿道带管造影在尿道狭窄(闭锁)手术后的应用价值.方法 男性尿道狭窄(闭锁)患者62例,年龄18～49岁,平均32岁.其中,44例行尿道端端吻合术,18例行黏膜替代尿道成形术.所有患者术后行尿道带管造影.如造影片提示尿道吻合口愈合良好.则拔除导尿管;如造影片提示尿道吻合口愈合不良,则继续留置导尿管,直到尿道带管造影片提示尿道吻合口愈合良好.结果 93.2%的尿道端端吻合术患者术后2～3周拔除导尿管.88.9%的黏膜替代尿道成形术患者术后2～3周拔除导尿管.尿道端端吻合术的手术成功率为88.6%,黏膜替代尿道成形术的手术成功率为83.3%.结论 尿道带管造影可以准确检测尿道狭窄(闭锁)患者手术后尿道吻合口愈合情况,在术后拔除导尿管时间的选择上有重要的指导意义.

Clinical Value of Pericatheter Urethrography

Objective To evaluate the value of pericatheter urethrography in urethral strictures or distraction diseases after surgical operation. Methods 62 men with urethral strictures or distraction diseases were treated with anastomotic urethroplasty or muco-sal graft substitution urethroplasty. In order to detect the healing status of urethral anastomotic stoma after surgery, all patients underwent pericatheter urethrography. The catheters were pulled out if the urethral anastomotic stoma healed well. Results 93. 2% patients undergone anastomotic urethroplasty, the catheters were pulled out two or three weeks after surgical operation. 88. 9% patients undergone mucosal graft urethroplasty, the catheters were pulled out two or three weeks after their surgical operation. The successful ratio of anastomotic urethroplasty and mucosal graft urethroplasty were 88. 6% and 83. 3 %, respectively. Conclusion Pericatheter urethrography can exactly detect the healing status of urethral anastomotic stoma of the patient with urethral strictures or distraction diseases that had underwent surgical operation. It will be a useful way to select the time of pulling out the catheter.
