Robotic-assisted reconstruction of a ureteral herniation into the psoas major fascia: A unique obstructive etiology and a surgical approach to management

Ureteral herniation has been described in urologic literature. Documented sites of herniation include the femoral and inguinal canals, obturator and sciatic foramen, and the thoracic cavity. Herein, we report what we believe to be the first described case of symptomatic obstruction from ureteral herniation through a defect in the psoas major muscle fascia and detail our approach to definitive robotic-assisted surgical management of this unique entity.
