Robotic-assisted excision of a prostatic utricle cyst in a 12-month boy with proximal hypospadia and 45X0/ 46XY karyotype.

INTRODUCTION: Prostatic utricle cysts result from incomplete regression of Mullerian duct structures and occur most frequently in males with perineal or peno-scrotal hypospadias. Utricular cysts may present with various signs and symptoms including urinary tract infection, pain and post-void incontinence, a palpable abdominal mass or recurrent epididymitis.

MATERIAL AND METHODS: We present a 12 months boy we treated due to proximal hypospadias in two stages, in association to a dysplastic undescended testis that was excised. The karyotype of the patient was 45X0/46XY and after successful hypospadias treatment, the mother complained of purulent discharge in the diapers. A sonogram showed a large cyst behind the bladder with heterogeneous content. The diagnosis of utricle cyst was confirmed by a NMR with detailed anatomy and low confluence of the neck of the cyst to the urethra.

RESULTS: We performed a robotic excision of the cyst consisting of careful dissection between bladder and rectum and a safe ligation of the communication of it to the urethra.

CONCLUSION: Patient outcome was uneventful. To the best of our knowledge this is the youngest patient with utricle cyst treated with robotic approach reported in the literature.
