The present case has been reported in the Indian Journal of Urology.

A 51-year-old man presented with acute urinary retension. On examination urinary bladder was palpable up to the umbilicus. After catheterization a vague lump was palpable on the left side of suprapubic region. On DRE prostate was of normal size, but a cystic mass was palpable arising from the upper boarder of the prostate. He was normotensive, normoglycaemic, with normal renal biochemical parameters.

Abdominal and pelvic ultrasonography could not find out the left kidney with presence of a retrovesical hypoechoic mass measuring 10x9x7 cm. A radionuclide scan failed to detect the presence of any functioning renal tissue on the left side. A contrast CT scan showed a nonenhancing retrovesical cystic mass (10 cm x 9 cm x 6.5 cm) with extrinsic compression on the left inferolateral wall of the urinary bladder and presence of a nonexcreting small hypoplastic kidney-like stucture on the same side.

Cystoscopy demonstrated an elevated bladder neck with smooth bulging of the left lateral wall of the urinary bladder. On exploration a large cystic seminal vesicle was identified on the left side. The mass was dissected, ligating the vas, till the opening of the ejaculatory duct. The left lower ureter was not found on through searching.

An exploration of the left renal area was done in the same time for exploration and confirmation of the kidneylike mass which unexpectedly reveals a rudimentary (3 cm) proximal part of the ureter. The kidney like structure including the rudimentary ureter was dissected out.

The histopathology of the resected specimen showed dysplastic renal tubules and fibrous tissue. The postoperative period was smooth and a follow-up ultrasound till one year did not reveal any recurrence of the cyst.
