A case of ectopic prostatic tissue in urinary bladder and uretero-seminal vesicle fistula with ipsilateral aplastic kidney is reported. A 29-year-old man was admitted to our hospital for residual sensation and perineal pain. Ultrasound examination revealed a cystic change in the right side of urinary bladder. C.T. and M.R.I. revealed a defect of a right kidney and ipsilateral ureteral dilation and seminal vesicle swelling. A cystscopy under lumbar anesthesia revealed a edematous cystic change of the right side of trigone and defect of the right ureteral orifice. Trans urethral resection of the wall of urinary bladder was simultaneously performed. And the contents of the cyst were sperum and old red blood cells. A retrograde ureterograph showed blind-ending ureter at L5 level and seminal vesicle swelling. A resected bladder tissue contained prostatic tissue. After operation he was free from complaints. Uretero-seminal vesicle fistula with ipsilater aplastic kidney is rare disease. In addition a case complicated ectopic prostatic tissue in urinary bladder was not reported in Japanese medical literature.
