Sexual impotence: the overlooked complication of a second renal transplant

The incidence of sexual impotence in 20 men who have received at least 2 kidney transplants was 65% compared to 10% after the first transplant. The importance was transient (2 to 4 months) in both affected men after the first transplant but permanent (2 to 10 years) in 6 men after the second operation. We attribute this increased percentage of impotence to the second end-to-end arterial anastomosis that requires division of the internal iliac arteries. We suggest that the second transplant be placed end-to-side into the common iliac artery.
