Abstract

A total of 15 patients with suspected urethral stricture of fistula underwent conventional retrograde urethrography & following sonourethrography with saline infusion of voiding against Eschmann penile clamp, in Gyeongsang & Chungnam National University Hospital from July, 1988 to June, 1989. The sonographic findings were asdiagnostic as the roentgen findings in 12 patients. When the length of the strictures assessed by each imagingmodality was compared to measurement at open urothroplasty of 2 patients, sonourethrography was consistently moreaccurate. Urethroscopy was done in all cases. Sonourethrography using distension technique of the urethra enabledclassification of the degree of spongiofibrosis, thus provided the guidance of direct vision internal urethrotomyin 9 patients. In 2 patients, the sonourethrogram identified periurethral tumor & urethral polyp which were notdefinitely analysed on the retrograde urethrgram. In the patient of posttraumatic postoprative urethrorectal fistula, residual fistuous tract was seen on both examinations. In 1 patient of stricture with severe periurethralscar, urethral stricture recurred after graft. No patient reported significant discomfort during thesonourethhrogram. The sonourethrogram provided valuable, dynamic, 3-dimenstional information about the luminal & extraluminal anatomy & pathology of the anterior urethra. The new method of sonourethrogram allows for theappropriate decision to be made easier for optimal treatment of urethal stricture, etc., and can be used as afollow-up study.
