A Case of Congenital Prepubic Sinus in a Pediatric Patient

Congenital prepubic sinus (CPS) is a rare urogenital anomaly, with only a few dozen cases reported domestically and internationally. Its etiology and diagnostic criteria remain incompletely understood. This article presents a case of a 10-year-old male child with CPS who presented with an 8-year history of a dorsal penile sinus tract. The diagnosis was confirmed through physical examination, two-dimensional ultrasonography, contrast-enhanced ultrasound (CEUS), urinary tract CT, and cystourethroscopy. The patient underwent complete laparoscopic sinus tract resection via a transumbilical three-port approach. At the 6-month postoperative follow-up, there was no recurrence or complications, and the patient recovered well.
