Surgical technique: utriculus masculinum excision by a laparoscopic-cystoscopic approach.

OBJECTIVE

A utriculus masculinum is encountered in 12% of hypospadias. However, patients rarely present with symptoms, such as post-void incontinence or infection. We describe a combined laparoscopic-cystoscopic approach to overcome the challenge posed by the location of the utriculus deep within the pelvis and to accurately identify the confluence of the utriculus with the urethra.

METHODS

A 12-year-old boy with Williams syndrome and previous hypospadias surgery presented with new-onset progressive day-time incontinence. Investigations (cystoscopy, urodynamics, MCUG) demonstrated a normal caliber urethra and the incontinence to result from a large utriculus masculinum. This video demonstrates the surgical technique: simultaneous utriculoscopy enabled the dome of the utriculus to be identified, laparoscopic dissection to progress under guidance of transillumination, and the urethral-utricular convergence to be clarified.

RESULTS

Histology demonstrated an inflamed utriculus with squamous metaplasia and cystitis glandularis. Symptoms resolved post-operatively and at 4 months follow-up, the patient remains dry by day.

CONCLUSIONS

A utriculus masculinum rarely requires excision. A combined laparoscopic-cystoscopic approach facilitates the delineation of the utriculus and allows its confluence to the urethra to be accurately determined.
