Summary: | Introduction. In males the ectopic ureter usualy drains into the prostate
(50%). During ureteric developement a thin membrane (Chawalla’s membrane)
separates the lumen of the ureter and the urogenital sinus at the point where
the ureter joins the urogenital sinus. This membrane ruptures allowing urin
to drain from the ureter to the urogenital sinus. The authors reported a case
of renal dysplasia associated with ipsilateral uretral ectopia mimicking
prostatic abscess. Case report. A subfebrile (37.3°C), 23-year-old patient,
otherwise healthy, presented with persistent ascending perineal pain
non-responsive to antibiotics and analgetics. Digitorectal examination (DRE)
showed asymmetric prostate with a soft, tender, buldging left lobe suggestive
of prostatic abscess. The diagnosis was suspected using transrectal
ultrasonography (TRUS), but the picture of the anechoic tubular structure in
the left lobe of the prostate with a proximal undefined extraprostatic
extension and a caudal intraprostatic blind end was incoclusive for the
definitive diagnosis of prostatic abscess. Magnetic resonance imaging (MRI)
was ordered and definitive diagnosis of renal dysplasia associated with the
ipsilateral ectopic ureter filled with inflamed content mimicking prostatic
abscess was made. Transurethral incision/minimal resection of the distal,
blindly closed end of left ectopic ureter was done. Endoscopic surgical
treatment was sufficient for relief of clinical symptoms. The patient’s
recovery was uneventful. Conclusion. To the best of our knowledge, a case of
renal dysplasia with the ipsilateral ectopic ureter mimicking prostate
abscess has not been reported so far. Cystic pelvic malformations in males
may result from too craniall sprouting of the ureteral bud, with delayed
absorption and ectopic opening of the distal end of the ureter.
