Ureteral obstruction due to compression by the vas deferens following Fowler-Stephens orchiopexy.

A rare complication following a difficult unilateral 1-stage Fowler-Stephens orchiopexy resulting in ipsilateral distal ureteral obstruction is reported. To our knowledge excessive vasal traction during orchiopexy causing partial obstruction at the ureterovesical junction has not been previously described. The complication arose when the transected spermatic vessels allowed tension to be placed solely on the vas when the testis was placed in the scrotum. The vas in turn compressed the ureter during bladder filling.
