Objectives: To report our single-center experience of the management of children with prostatic utricle cysts.
Methods: We retrospectively analyzed 15 children who were incidentally found to have a prostatic utricle cyst and were admitted to our department between October 2013 and August 2020. Clinical characteristics and management were collected and catalogued.
Results: Recurrent genitourinary tract infections were the most frequent complaint, and two-thirds of patients also had hypospadias. A connection between the posterior urethra and the prostatic utricle cyst was found in all cases. Two patients directly had their progressively enlarging prostatic utricle cyst resected laparoscopically. Endoscopic techniques were used in 13 patients, two of whom underwent laparoscopic excision for repeated symptoms. The mean (range) follow-up period was 34.9 (2-82) months. No recurrences were observed in four patients who underwent prostatic utricle cyst excision and eight patients who received endoscopic treatment. Three patients had recurrent symptoms after endoscopic treatment and were managed by nonsurgical treatment.
Conclusions: Prostatic utricle cyst is a rare disease which can cause recurrent genitourinary tract infections. Extra attention should be paid to evaluation for prostatic utricle cyst in children with external genital anomalies. Retrograde urethrogram and magnetic resonance imaging are useful tools with which to distinguish prostatic utricle cyst from other cystic lesions that are located in the midline pelvis in male patients. Individualized treatment is appropriate when considering fertility preservation, recurrences and malignancy. Laparoscopic excision is feasible for symptomatic and large prostatic utricle cyst. Regular long-term monitoring is recommended for all patients with prostatic utricle cyst.
