[Cyst of the prostatic utricle: report of a case complicated by giant lithiasis]

We report a case of prostatic utricle cyst complicated with giant lithiasis.

A 42 year old man with history of surgery for bilateral cryptorchidism and hypospadias in his infancy, presented with initial and terminal hematuria and a digital rectal examination showing a rocky, smooth enlargement of the anterior rectal wall. Prostatic specific antigen was normal. Transrectal and transabdominal ultrasound showed a large retrovesical calcification and intravenous pyelogram showed normality of the upper urinary tract. The patient underwent a complete resection through a suprapubic extraperitoneal approach without complications. Histopathology revealed a 10 cm long prostatic utricle cyst complicated with lithiasis.

The prostatic utricle cysts are rare in clinical practice and associate with anomalies of testicular descent and hypospadias. They have a difficult differential diagnosis and indication for treatment depends on presenting symptoms, size and complications.
