[The pathological prostatic utricle: two case reports].

The prostatic utricle is a small vestigial diverticulum on the posterior surface of the prostatic urethra. It is considered to be pathological when it is abnormally dilated. The prostatic utricle is revealed by signs of vesical irritation and dysuria, sometimes associated with a retrovesical mass on examination. The authors report two cases of pathological prostatic utricle. The first case was an 11-year-old boy presenting with dysuria. Retrograde cystourethrography confirmed the diagnosis. The utricle was resected via a transtrigonal intravesical approach. The second case was a 25-year-old man who presented with dysuria associated with a pelvic mass. IVU and ultrasonography suggested a diagnosis of retrovesical cyst. This patient underwent incomplete resection of the utricle via a retrovesical approach. Based on a review of the literature, the authors emphasize the need to look for a prostatic utricle in a young subject presenting with dysuria, particularly in patients with a malformation of the genitourinary tract (hypospadias, renal agenesis). All pathological prostatic utricles must be treated surgically. The incision is transtrigonal in medium-sized utricles and transperitoneal in large utricles. The utricular cavity must be resected as completely as possible.
