“…CPS is a tract located at the skin overlying the symphysis pubis, superior to the base of the penis or clitoris, and extending proximally, but does not communicate with the anterior bladder wall [2, 3]. After the first report of CPS in 1987, around 50 cases have been reported in the literature so far [4].…”

Background Congenital prepubic sinus is a rare anomaly found in the midline of the lower abdomen. Congenital prepubic sinus is usually asymptomatic in neonates, and a diagnosis is often achieved later in life after spontaneous extrusion of purulent material from the pre-existing hole in the pubic region. We present a case of congenital prepubic sinus presenting with purulent discharge after circumcision. Case summary A 4-year-old Caucasian boy presented to our urology out-patient clinic with purulent discharge from the distal part of the dorsum of his penis. He had a history of circumcision performed at a different center, 6 months ago. His parents stated that although various antibiotics were used, the purulent discharge continued for 6 months and the child had no complaints before circumcision. His condition was reported as superficial dorsal venous thrombosis, known as penile Mondor disease, in magnetic resonance imaging that was performed in the previous hospital. A physical examination revealed a small pinhole lesion at the distal part of his penis and a rigid cylindrical tube extending to the proximal side of his penis. We performed fistulography by injecting contrast material through a small angiocatheter and confirmed the diagnosis of prepubic sinus. Surgical exploration was performed and a long sinus, apparently ending as a fibrous tract at the anterior surface of his pubic symphysis, was found and resected. Conclusions Before congenital prepubic sinus surgery, it is critically important to rule out penile Mondor disease and the possibility of a circumcision complication (especially infective complications) mimicking congenital prepubic sinus.

“…Congenital prepubic sinus is a tract originating in the skin overlying the symphysis pubis, superior to the base of the penis or clitoris, and extending to, but not communicating with, the anterior bladder wall [3]. There are four generally proposed theories for the etiology of Congenital prepubic sinus: First anomaly of abdominal wall closure [4]; and second urethral developmental anomaly, a variant of dorsal urethral duplication [1,2,[5][6][7][8].…”

Congenital Prepubic Sinus (Type 2 Stephens Variant of Epispadiac Dorsal Urethral Duplication): An Uncommon Anomaly

Variants of congenital prepubic sinus have been reported rarely, and because the anatomic features often differ from each other, a consensus concerning the embryology and classification was not achieved yet. Various names including congenital prepubic sinus, sub pubic fistula, prepubic dermoid sinus, and suprapubic dermoid sinus, were used to identify these lesions, and, among the classifications available, none seems to clearly describe this entity. We present a 2-year old boy with a case of epispadiac variant of urethral duplication in which the duplicated urethra presented as a prepubic sinus. We report this uncommon anomaly and review the scattered published reports to improve the global understanding of this uncommon congenital lesion.

“…This congenital tract locates at the skin overlying the symphysis pubis superior to the base of the penis and ends as a fibrous non-communicating2 tract at the surface of the triad urachus–bladder–urethra. CPS rarely extends to umbilicus or has a connection with bladder or urachus that might cause infection 3.…”
