Abstract
The incidence and pathogenesis of sexual dysfunction were studied in 16 male renal allograft recipients. In 9 patients with bilateral renal transplants where both internal iliac arteries were occluded, nocturnal erections were absent and a penile arterial pulse could not be palpated. Of 7 patients with 1 renal allograft 4 demonstrated penile nocturnal tumescence and the penile pulse could be palpated in 5. Since interruption of pelvic arterial blood supply appears to contribute to impotence in renal transplant recipients consideration should be given to the use of the external iliac artery for arterial anastomosis. Patients (2) were treated successfully with an inflatable penile prosthesis.
