Аннотация

Aim To determine the practical and diagnostic value of transperineal ultrasound imaging of the internal pudendal artery (IPA) in patients with arteriogenic erectile dysfunction (ED). Materials and methods Transperineal IPA and penile Doppler ultrasonography was performed in 50 healthy young male volunteers aged 23.6±3.4 years without ED (IIEF-5 score of 21-22) and 60 patients with ED (IIEF-5 score of 6-18, mean age 49±4.6 years), including 30 men with prostate cancer (PCa) after comprehensive treatment and 30 patients with type 1 and type 2 diabetes mellitus. To determine the diagnostic value of the transperineal IPA imaging, the results were compared with the findings of magnetic resonance or contrast-enhanced dynamic CT angiography of the iliac arteries. Results In all healthy men no abnormalities were found in the perineal primary arterial blood flow, in 100% of cases perineal branch of IPA was rectilinear, while patients with arteriogenic ED had low IPA and penile peak systolic blood flow velocity (р<0.05), pathologically altered type of blood flow and non-rectilinear course of IPA, stenosis and occlusion in the pelvic and extrapelvic branches of IPA. When comparing the findings of IPA Doppler ultrasound and angiography studies of the small pelvis in healthy men, they completely matched, showing satisfactory arterial IPA perfusion, absence of stenoses or occlusions. Sensitivity and specificity of the transperineal IPA ultrasound imaging were 95% and 90%, respectively. Conclusion Transperineal IPA ultrasound imaging allows to assess the important morphometric features of the perineal branches of IPA - the arterial diameter, the response to stimulation, the course of the artery, the type of arterial blood flow, the presence or absence of arterial stenoses and occlusions, and to measure peak systolic blood flow velocity.
