Antenatal intervention: jeopardizing life or limb?

The association of limb loss with antenatal urologic intervention has recently been questioned. At present, no such cases have been reported. We present a case of antenatal vesicoamniotic shunting for posterior urethral valves in which the shunt entered the right lower extremity and coursed subcutaneously over the femoral triangle and inguinal canal and into the bladder. Although the limb was intact, we present images and a discussion of the potential for extremity injury with antenatal urologic intervention.
