Changes in hemodynamics in the penis at Diabetic nephropathy and the Rehabilitation of Erectile function

Abstract

Aim: To determine the possible positive influence on correction of erection duration with redistributing of blood flow in pelvic arteries. Materials and methods: Blood fl ow indices were determined with the methods of color Doppler ultrasound diagnostics of penis arteries in 9 middle-aged males with erectile dysfunction, in whose anamnesis there had been diabetic nephropathy. Results: We determined that the maximum blood flow velocity in the cavernous arteries of the penis was 31.5 cm/sec on average, and diastolic blood flow velocity was 13.4 cm/sec, compared to 60 cm/sec and 25 cm/sec respectively in the norm. The resistive index decreased to 0.58 compared to 0.92 in the norm. Gotten indices show the presence of erectile arterial dysfunction in middle-aged males with diabetic nephropathy. Performed experiments in animals with directing of arterial blood flow from the caudal sciatic artery to the deep and spinal arteries of the penis showed widened lumen in them to 50% in average that causes the continuous erection. Conclusions: According to the data of the Doppler ultrasound of the penis in middle-aged males, in whose anamnesis there had been diagnosed diabetic nephropathy, we found out bilateral cavernous dysfunction. According to the data of the angiography exclusion of the caudal sciatic artery directed the blood flow into the internal pubic artery and its final branches, the deep and spinal arteries of the penis with signif i cant (to 50% in average), increasing of their internal diameter and continuous erection.
