Indications: used to evaluate the morphology and function of the bladder and urethra and to evaluate for vesicoureteral relux. Specific indications include urinary tract infection, posterior urethral valves, dysuria, frequency, anuria, anorectal malformations to look for fistulas, intersex problems, hydronephrosis / hydroureter.
The male urethra is composed of the posterior urethra, the membranous urethra, the bulbous urethra and the penile urethra. The female urethra corresponds to the male posterior urethra.
Normal variants include Cowper's gland ducts which may fill with voiding, producing a tubular contrast filled structure originating ventrally from the perineal portion of the bulbous urethra that should not be mistaken for urethral diverticula, duplication, or fistulae.
