To evaluate the correlation between penile Doppler ultrasound (US) findings and erectile function scoring test in patients with diabetes mellitus requested penile Doppler US examination and suffering from erectile dysfunction.
Materials and Methods: Twenty-seven patients who underwent penile Doppler US were recruited to this prospective study. Penile blood flow following intracavernosal papaverine injection using Doppler US was evaluated in the ultrasound unit. The peak systolic velocity and end-diastolic velocity were recorded and the diagnosis according to Doppler US was determined. Erection score according to Erection Hardness Grading Scale was evaluated, which ranked the scores from 1 to 4. A scoring for erectile function was performed with the International Index of Erectile Function (IIEF-5), and the Sexual Health Inventory for Men (SHIM) was defined. Doppler US findings were compared with SHIM scales.
Results: There were a total of 27 patients with a mean age of 55.74±9.02 (39-70) years. Among these patients, 21 (78%) had abnormal penile Doppler US findings. According to Doppler US findings, patients were classified as normal (n=6), borderline for arterial insufficiency (n=2), arterial insufficiency (n=5), and venous insufficiency (n=14). No complications were detected in any of the patients due to penile Doppler US evaluation. Erection was not completely enough except in 2 patients. The lowest erection hardness and the lowest IIEF-5 scores were detected in the patients with arterial problems.
Conclusion: The rate of vascular problems in diabetic men with erectile dysfunction is high and venous insufficiency was found to be more often in our study.
