Ectopic ureter, renal dysplasia, and recurrent epididymitis in an infant: case report and review of the literature.

The most common etiologies of acute scrotum in boys <1 year of age are torsion of the testis or an appendix, urogenital anomalies, and epididymitis. We report an infant with recurrent epididymitis associated with single-system ectopic ureter opening into the seminal vesicle and dysplastic right kidney. Treatment included nephroureterectomy.
