A study of 1170 patients operated on in the lithotomy position found postoperative neurapraxic complications in 1% of patients. 104 Other, less commonly injured nerves include the obturator and femoral cutaneous nerves. One series found that the most common lower extremity neuropathies associated with procedures in the lithotomy position were common peroneal (81%), sciatic (15%), and femoral (4%). Neurologic injuries related to the lithotomy position may affect the femoral, sciatic, and common peroneal nerves. 101,102 The frequency of perioperative complications may increase with an exaggerated or “high” lithotomy position because the angle of the hips and lower extremities in this position is even more pronounced. In addition to neurologic complications, which are discussed here, other complications that have been reported after procedures in the lithotomy position include lower extremity compartment syndrome, venous thrombosis, and rhabdomyolysis. 100 An understanding of potential postoperative complications related to this position is essential to the care of urologic patients. The patient's legs are placed into stirrups, with the knees bent such that the lower legs are parallel to the plane of the torso. Standard lithotomy position requires the patients' legs to be separated from the midline into 30 to 45 degrees of abduction, with the hips flexed until the thighs are angled between 80 and 100 degrees.
