目的 研究引起尿道狭窄术后不久出现排尿困难的尿道形态学改变，为临床及时采取对策提供依据。方法 全尿道超声显像技术检测２８个病例。检测时间术后１周内有１２例，２￣４周１５例，第１０周１例。结果 ２８例中２７例能找到尿道吻合口病理形态改变，表现为狭窄１６例，其中狭窄位于后尿道１４例，球部２例；瓣状物３例，均位于膜部；假道８例，７例位于前列腺部，另１例在球部。结论 超声对明确术后近期出现排尿困难的病因有

A Study of Sonourethrography on Traumatogenic Urethral Strictures Postoperatively :Ultrasound Detection of Patients with Dysuria Postopertively

Objective To investigate the urethral pathological morphology at urethral anastomotic site in patients withdysuria occurred not longer after urethral operation. OMethods Twenty-eight cases of patients with dysuria after operationunderwent sonourethrography. Of all ,12 cases were detected in 1st week postoperatively ,15 cases during -nd to 4th week ,1 in 10th week. Results Pathologic changes at urethral anastomotic site could be found in 27 cases. These sonographic appearances included urethral stricture in 16 cases (14 located at posterior urethra and 2 in bulbar urethra) ,flap valve in 3 (alllocated at membraneous urethra) ,false passage in 8 (7 located at the anterior part of the prostate ,1 at bulbar urethra) . Onlyone case had no abnormal appearance sonographically. Conclusion Urethrosonography postoperatively has great value indetermining causes of dysuria ,especially not longer after urethral operation.
