A Case of Congenital Prepubic Sinus

Introduction

Congenital prepubic sinus (CPS) is an infrequently seen, congenital anomaly forming a tract that communicates between the skin overlying the symphysis pubis, superior to the base of the penis or clitoris, and which usually extends back to the anterior wall of the bladder or umbilicus [1]. The etiology of CPS is not fully established yet. This lesion was first reported by Campbell [2]. He suggested that these tracts may represent a localized failure of midline fusion of the lower abdominal wall [2]. Others have reported that their cases may represent a variant of epispadiac urethral duplication [1] [3] [4] [5] [6]. CPS and urethral duplications were suggested to be related embryologically [5]. This proposal has not been fully established yet. Moreover, CPS was not associated with other congenital genitourinary anomalies.
