Suprapubic versus prepubic sinus: a literature review.

Area of Science:

• Pediatric Surgery
• Urology
• Developmental Biology

Background:

• Urachal remnants are congenital anomalies arising from the incomplete obliteration of the urachus.
• Urachal sinus typically presents with umbilical discharge, but rare variants can have extraumbilical openings.
• Distinguishing between different urachal anomalies like suprapubic sinus (SPS) and prepubic sinus is crucial for appropriate management.

Observation:

• A 2-year-old boy presented with a prepubic sinus, an uncommon presentation of a urachal anomaly.
• The sinus tract's pathway and epithelial lining differed from typical suprapubic sinus (SPS).
• The prepubic sinus was successfully managed with surgical excision.

Findings:

• The case highlights a rare presentation of a urachal sinus with a prepubic opening.
• Surgical excision proved an effective treatment modality for this prepubic sinus.
• Literature review suggests distinct characteristics differentiating prepubic sinus from SPS.

Implications:

• Accurate diagnosis and differentiation of urachal anomalies are essential for effective surgical planning.
• This case expands the understanding of urachal sinus presentations and management.
• Further research into the embryological basis and clinical spectrum of urachal remnants is warranted.
