Introduction: l
Standard techniques for evaluation of male urethral stricture disease require instrumentation and, in the case of radiography, radiation exposure. Current ultrasound assessment either mimics retrograde urethrography (RUG) or produces an antegrade study by Credé voiding. Our technique merely requires compliant patients to void into a container while being examined with an ultrasound transducer placed at the perineum.
Methods:
A conventional 7.5 MHz “small parts” transducer at the perineum is initially aligned along the line of the proximal corpus spongiosum, angled towards the prostate. The patient is then asked to void. As the bladder neck and urethra open, the lumen may be followed distally by slight angulation and movement of the probe. A significant length of urethra may be thus followed, although very distal strictures require a deft repositioning of the probe.
Results:
We present our initial series of 7 patients with suspected stricture. All had corroborative RUG, 2 patients underwent subsequent urethroplasty, 1 had visual internal urethrotomy, 1 urethral dilation, 3 await urethroplasty. Sonographic findings recorded greater length of stricture and multiplicity of stricture site than RUG. No patient reported any discomfort from our procedure.
Conclusions:
Ultrasound voiding urethrography is a quick and simple technique that, in compliant patients, produces useful information about the presence and extent of stricture and may have particular application in post-treatment follow-up.
