![]() ![]() ![]() A previous study reported that the incidence of ipsilateral renal agenesis or dysplasia was only 0.00464% when incidentally noted in ultrasonography and thought to be a pelvic cyst. Our young male patient suffered from scrotal discharge, which is not usually associated with renal agenesis. 3 Although magnetic resonance imaging has been reported to be more advantageous than computed tomography or ultrasonography, 1 it is not routinely used to identify this disease. 1 It is usually discovered incidentally, 2 and computed tomography and ultrasonography have been reported to be of limited use in its detection. Ureteric bud remnant with renal agenesis is a rare congenital disease that has only been reported in a few case reports. The specimen is confirmed as ureter histologically (Fig. The tube was ligated and the cut end was sent for surgical pathology. The direction of this tubule was compatible with the development of the left ureter. The setting of mobile C‐arm X‐ray system is conversely, so the picture showed mirror image. Contrast medium was injected and revealed a channel‐like structure about 15 cm in length with a blind end in an upward direction (Fig. For further investigation, patient was placed at supine position, and mobile C‐arm X‐ray system was setting for image study. ![]() Near the tail of the sinus, a connection was noted to a channel‐like structure. During surgery, the wound was deepened along with the sinus to the retropubic bone. Because of a recurrent local heat sensation, turbid discharge, tenderness, and infection, he underwent resection of the infectious sinus (Fig. ![]() 1a) and a cystic lesion over his left scrotum (Fig. However, the cystourethroscopy examination revealed that there was no left ureteral orifice.Ĭomputed tomography revealed agenesis of his left kidney (Fig. An anal fistula was ruled out by digital rectal examination, and a urethra‐cutaneous fistula was also excluded by cystourethroscopy. Infectious sinusitis or a fistula was impressed initially. On physical examination, a pinhole was noted over his left scrotum with squeezing pain and discharge. A 41‐year‐old man presented to our outpatient department with intermittent discharge of a turbid fluid (<1 mL) from his scrotum. ![]()
