2024年8月12日 · Urethrography refers to the radiographic study of the urethra using iodinated contrast media and is generally carried out in males.

Retrograde urethrography (RUG) and voiding cystourethrography (VCUG) are complementary studies for evaluating the male urethra. The RUG evaluates the anterior urethra and the VCUG evaluates the posterior urethra.

2024年4月4日 · Retrograde urethrography is the modality of choice to investigate urethral injuries. It will demonstrate extraluminal contrast, which has extravasated from the urethra at the site of injury.

2024年10月15日 · Urethrography refers to the radiographic study of the urethra using iodinated contrast media and is generally carried out in males. Terminology When the urethra is studied with instillation of contrast into the distal/anterior urethra it has been referred to as: retrograde urethrography (RUG)...

2024年8月28日 · the inferior margin of the obturator foramen is the osseous landmark during retrograde urethrography for the location of the urogenital diaphragm type III: injury to the membranous urethra, extending into the proximal bulbous urethra (i.e. with laceration of the urogenital diaphragm)

The male urethra has anterior and posterior components, with further anatomical sub divisions. The anterior urethra is typically imaged by an ascending urethrogram and the posterior urethra, by a descending urethrogram. Studying the urethra is ...

2025年1月8日 · Retrograde urethrography is the primary method used to image anterior urethral stricture. In posterior urethral strictures following blunt trauma, simultaneous antegrade cystourethrography and retrograde urethrography are often required to …

2024年9月11日 · While the urethra is well outlined in both procedures, retrograde urethrogram (RUG)/ascending urethrography (ASU) is better to visualize anterior urethral abnormalities and VCUG is better for posterior urethral abnormalities. Additionally, VCUG is performed for detection of bladder abnormalities and vesicoureteric reflux (VUR).

2024年10月10日 · Gross anatomy. The male urethra measures, on average, 18-20 cm in length 6.It commences at the internal urethral orifice in the trigone of the bladder and opens in the navicular fossa of the glans penis at the external urethral meatus, which is the narrowest part of the urethra 5.. The male urethra can be divided into anterior and posterior portions.
