Congenital anterior urethrocutaneous fistula at the penoscrotal junction with proximal penile megalourethra: A case report

Abstract

Congenital anterior urethrocutaneous fistula and megalourethra are both rare anomalies. These anomalies are commonly associated with other anorectal or genitourinary anomalies and evaluated with voiding cystourethrography. We examined a 34-month-old boy who presented with a fistula at the penoscrotal junction. A voiding cystourethrogram showed a jet of urine coming through the fistula and proximal saccular dilatation of the penile urethra. We present the imaging findings of the first case of an association between a congenital anterior urethrocutaneous fistula at the penoscrotal junction and a proximal penile megalourethra. We also discuss the etiology, management, and differential diagnosis of this entity, and review the literature.

Congenital anterior urethrocutaneous fistula: A case report and review of literature

“…Adjunct imaging such as ultrasound abdomen & cystourethrogram are necessary to evaluate for other genito-urinary anomalies. The latter can show the presence of double urinary flows, one from the tip and the other from the fistula 3 …”

Congenital anterior urethrocutaneous fistula: A systematic review

“…Eight patients with chordee and 19 with associated genitourinary anomalies were reported up to date with CAUF cases. [167891314151617181920] Meanwhile, associated other anomalies may be detected in patients with CAUF. Based on our systematic review, anomalies which may be noticed by physical examination such as undescended testes ( n = 5), inguinal hernia ( n = 2), penoscrotal transposition ( n = 1), bifid scrotum ( n = 1), duplicated urethra ( n = 1), megalourethra ( n = 2), anorectal malformation ( n = 11), and congenital heart disease ( n = 2) were detected in cases mentioned in the literature.…”

“… 2 The most common fistula location was subcoronal, followed by the mid-penile with proximal penile and penoscrotal being the least reported location. 4 …”
