Vascular Hemodynamic Effects of Penille Revascularization Surgery and the Role of Resisti̇ve Index in Follow-up

Abstract Purpose The aim of this study is to measure the effects of penile revascularization surgery performed in vascular origin erectile dysfunction on penile vascular hemodynamics and to determine the importance of vascular parameters in postoperative patient follow-up. Methods A total of 35 patients who underwent penile revascularization surgery due to vascular erectile dysfunction were included in this study. In the preoperative period and at the 3rd postoperative month, penile color doppler ultrasonography was performed to evaluate cavernosal arteries, dorsal arteries, deep dorsal vein and inferior epigastric artery separately. During this evaluation, peak systolic velocity, end diastolic velocity, and resistive index were measured. The International Index of Erectile Function questionnaire was applied to all patients in the preoperative period and at the 3rd postoperative month. The relationship between changes in International Index of Erectile Function questionnaire score and penile vascular hemodynamic changes in the postoperative period was evaluated. Results The average preoperative resistive index values of the operated cases were determined as 0.74 ± 0.07/0.73 ± 0.09 cm/s for the right cavernosal artery and left cavernosal artery, respectively. The same values were found as 0.95 ± 0.09/0.96 ± 0.06 cm/s at the last postoperative control. The average International Index of Erectile Function − 5, 15 scores were determined as 8.52 ± 4.83, 19.4 ± 8.54, respectively, in the preoperative period, and 15.26 ± 4.50, and 35.76 ± 13.65, respectively, at the last postoperative follow-up. Conclusion This study showed that the resistive index can be used in the diagnosis of vascular originated erectile dysfunction and in the postoperative follow-up of the patients.
