Prepubic sinuses, rare congenital urinary tract anomalies, are proposed to be classified as primitive urogenital sinus fistulas. This classification clarifies their anatomy and embryology based on 22 reported cases.

Area of Science:

  • Urology
  • Embryology
  • Congenital Anomalies

Background:

  • Prepubic sinuses are infrequent congenital anomalies of the urinary tract.
  • Limited case reports exist, necessitating further clarification of their characteristics.

Observation:

  • The study presents two clinical cases of prepubic sinuses.
  • A comprehensive review of 20 previously reported cases was conducted.

Findings:

  • The authors propose reclassifying prepubic sinuses.
  • Lesions are suggested to be fistulas of the primitive urogenital sinus, not dorsal urethral duplications.
  • Three distinct anatomic types are identified: high (urachal remnant), middle (bladder), and low (urethra).

Implications:

Related Experiment Videos

  • This new classification aids in understanding the embryologic origins of prepubic sinuses.
  • It provides a framework for diagnosing and potentially managing this rare anomaly.
  • Further research into primitive urogenital sinus fistulas is warranted.
