“…The parents of the present patient were no longer alive, although screening the patient’s children by ultrasonography failed to detect any uropathological condition. Physical examination may detect abdominal or flank tenderness, or possibly a palpable mass in the abdomen or rectum [ 5]. In the present case, ultrasonography speeded the diagnostic evaluation, an experience also reported by Fannin et al [ 5].…”

“…Physical examination may detect abdominal or flank tenderness, or possibly a palpable mass in the abdomen or rectum [ 5]. In the present case, ultrasonography speeded the diagnostic evaluation, an experience also reported by Fannin et al [ 5]. The use of transrectal or transvaginal probes may facilitate the assessment of the prevesical section of the ureter(s) and may be helpful in identifying and localizing the insertion point of (an) ectopic ureter(s), as can CT [ 6].…”

a marked delay in excretion and hydronephrosis on the Case report left. A voiding cysto-urethrogram failed to detect VUR and a renal scan showed no function in the left kidney. A 37-year-old man presented with a left-sided scrotal swelling, dysuria and fever consistent with the clinical CT of the abdomen showed a hydronephrotic left kidney with a dilated tortuous ureter (Fig. 2) involving the left diagnosis of acute epididymitis. During the last few years he had experienced similar episodes of epididymitis on seminal vesicle and ending ectopically in the prostate. On cystoscopy, the right ureteric orifice was positioned the left, with no further investigation. The patient was married and had fathered four children. Urine analysis normally, but no left orifice could be identified. The epididymitis resolved completely under treatment with showed white blood cells (WBC, 500/mL) and no bacteriuria; urine culture was sterile and cultures for Chlamydia, oral antibiotics. After 4 weeks, a left nephroureterectomy and resection of the left seminal vesicle Ureaplasma, Mycoplasma and tuberculosis were negative. Haematology and biochemical screens were within was performed, revealing a trifid ureter passing the left seminal vesicle and ending blindly in the prostate (Fig. 3). normal limits apart from a WBC count of 17 500/mL. Ultrasonography revealed a normal right kidney but onThe post-operative course was uneventful and the patient has had no recurrence of epididymitis for 12 months. the left there was marked hydronephrosis with no evidence of a renal cortex; a dilated and tortuous ureter could be followed down to the bladder base.

MR urography findings of a duplicated ectopic ureter in an adult man

2000

In this report we present the imaging findings in an adult male with a duplicated ectopic ureter which inserted into the prostatic urethra. The appearances at excretory urography, US, CT, and MR urography are described together with the potential pitfalls of the imaging techniques. Both US and MR urography accurately image the collecting system from the kidney to the point of distal ureteral insertion, and in our patient, MR urography provided similar information to US.

“…Ectopic ureters may occur if the ureteral bud develops more cranial than normal and does not insert into the correct region of the bladder. 4 Clinical signs of ectopic ureter include dysuria, increased frequency of ~rination,~ or urinary incontinence since birth.536 Other causes of urinary incontinence that should be considered include congenital neurological disorders such as lower motor neuron lesions causing urinary retention and overflow inconcongenital urethral sphincter incompet e n~e ,~, ' hypoplastic bladder, hormonal imbalance, persistent urinary tract injury to the sacral segment of the spinal cord or sacral nerves, and multifocal en~ephalomyelitis.~ Various techniques have been used to diagnose ectopic ureters, including retrograde cystography, intravenous ~r o g r a p h y ,~.~ double-contrast cystography: positive contrast urethrography in males or vaginourethrography in females,8 and detection of red-stained urine via endoscopy after administration of azo~ulfarnide.~ Contrast radiography followed by ultrasonography of the bladder has been used to identify ureterovesicular junctions." Ectopic ureters were diagnosed by the absence of a ureteral jet and observation of the ureter bypassing the bladder.…”
