“…Since 1989 sonourethrography has been increasingly used by urethra surgeons since from a diagnostic point of view it is equally reliable as retrograde urethrography and facilitates the evaluation of two key diagnostic elements for the surgeon: the extent of the stenosis and the involvement of the periurethral spongy tissue [26,27,28,29]. Many surgeons perform the exam in the operating theater immediately before incision for urethrotomy [30,31]. At sonourethrography stenoses appear as constrictions, with hyperecogenic submucosa that may be due to involvement of the adjacent spongy tissue [32,33].…”

The male urethral imaging and pathology is not widespread in the radiology literature because this part of the urinary tract is easily studied by urologists with clinical or endoscopic examinations. Ultrasonography and MR imaging are increasingly being used in association with voiding cystourethrography and retrograde urethrography. The posterior urethra is being studied with voiding cystourethrography or voiding sonography which allows the detection of bladder neck pathology, post-surgical stenosis, and neoplasms. The functional aspects of the bladder neck and posterior urethra can be monitored continuously in patients with neuromuscular dysfunction of the bladder. The anterior urethral anatomy and pathology is commonly explored by retrograde urethrography, but recently sonourethrography and MR imaging have been proposed, distending the lumen with simple saline solution instead of iodinated contrast media. They are being used to study the urethral mucosa and the periurethral spongy tissue which can be involved in the urethral pathologies such as strictures, diverticula, trauma, and tumors. Imaging has an important role to play in the study of the diseases of the male urethra since it can detect pathology not visible on urethroscopy. The new imaging techniques in this area, such as sonography and MR, can provide adjunct information that cannot be obtained with other modalities.

“…Malformations of the anterior urethra (Das 1992;Chiou et al 1996) are due to complete or incomplete stenoses or segmentary atresia, duplications and congenital dilatations (megalourethra). Other malformations include hypospadia and epispadia, which are associated with enlargement of the prostatic utricle and müllerian duct remnants.…”

“…This was in addition to the obvious advantages of relative non-invasiveness, ready availability and lack of ionising radiation exposure. In terms of comparison between the two methods in assessing stricture disease, a number of studies have demonstrated that ultrasound is at least as effective as contrast urethrography in assessing length and extent of stricture [6][7][8][9][10] and indeed may be superior, particularly in the evaluation of short strictures [11,12] and strictures situated within the bulbar urethra [13,14]. Recent advances in ultrasonographic techniques (such as extended-field-of-view imaging) further add to the utility of the technique, and are particularly useful in demonstrating pathology to non-radiologists [15] at clinic radiological meetings.…”

Ascending and descending techniques are used to demonstrate the male anterior urethra. The authors developed an ultrasound approach with the patient compressing his own urethra manually during voiding to achieve distension of the urethra with urine. The subsequent sonourethrography is more accurate than conventional fluoroscopic contrast studies in defining urethral filling defects and is as accurate for the demonstration of strictures. The technique has replaced contrast urethrography at the authors' institutions for the routine evaluation of the anterior urethra.
