Scrotal hernia of the ureter in association with posterior urethral valves.

Posterior urethral valves are a common obstructive uropathy causing severe hydroureteronephrosis. Ureteral herniation is very rare and often misdiagnosed. We report a male infant with posterior urethral valves who had increased persistent hydronephrosis despite prior successful ablation. Further examination revealed a paraperitoneal inguinal ureter herniation to be responsible for the clinical status.
