Renal dysplasia with the ipsilateral ectopic ureter mimicking abscess of the prostate

In males the ectopic ureter usually 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.
