Objective: To determine the overall long-term success of penile revascularization surgery in the treatment of vasculogenic erectile dysfunction and also to investigate the effect of risk factors on the results of a modified Furlow-Fisher technique. We completed our revascularization surgery results in our 50 erectile dysfunction patients having no risk factors except diabetes with a long term follow-up.

 Materials and Methods: Between 2004 and 2015, 225 patients with a mean age of 47.2 (range:23–73) years underwent penile revascularization surgery. Among them, 50 patients were diagnosed as having diabetes mellitus and completed the mean 60,94±1,34 months follow-up. Following the physical examination and assessment of blood tests, all the patients were referred to the internal medicine, neurology, psychiatry and anesthesiology departments for a routine interview. Before the operation, a urological assessment was made using color Doppler ultrasonography, cavernosometry, and electromyography of the corpus cavernosum (CC-EMG). At least five points of increase in the IIEF-5 score during the latest patient visit in the postoperative period compared with the preoperative period was regarded as improvement (surgical success).

Results: The mean preoperative and follow-up total IIEF scores were 28.1±5.7 and 42.2±6.3, respectively (p<0.05). The mean IIEF-5 scores were 8.3±2.2 and 17.7±2.1 preoperatively and at the end of follow-up, respectively (p<0.05). The mean score in the erectile function domain of IIEF was 11.6±3.4 before the operation and 21.7±6.1 at the end of follow-up (p<0.05). According to the IIEF-15,32 patients achieved a no-ED threshold value of >26. According to the IIEF-5, the surgery was again successful in 35 of 50 diabetic patients (70%).

Conclussions: We suggest that penile revascularization surgery could be an alternative choice before penile prosthesis implantation in those patients having no risk factors except diabetes which is under control.
