title: Congenital prepubic sinus.
abstract: Prepubic sinuses are rare congenital anomalies of the urinary tract. There have been few case reports in the literature. The authors describe 2 clinical cases of this entity. A review of the 20 cases previously reported, to clarify the anatomic features and the embryology of this infrequent congenital anomaly, also is reported. Furthermore, the authors propose to classify these lesions not as dorsal urethral duplications but as fistulas of the primitive urogenital sinus, with 3 anatomic types: high, toward the urachal remnant; middle, to the bladder; and low, reaching the urethra.
