CT of the abdomen, plain and post contrast –
Both ureters present with normal diameter and expected opacity in the excretory pyelogram phase. An intramural bypass of the vesicourethral junction of the left ureter is seen. The left ureteral orifice appears to be located caudal to the vesicourethral junction within the pelvic urethra. Level with the vesicourethral junction a small focal accumulation of contrast media is noted within the pelvic urethra. The right ureteral orifice is slightly cranial to the vesicourethral junction. The position of the urinary bladder neck is cranial to the pubic rim. The total width of the urethra is 7 mm. The luminal width cannot be determined owing to the lack of dilation/contrast accumulation.
