Correlation Doppler ultrasound index vascular on kidneys, penis, and digital arteries in patient with systemic sclerosis: what obstacles?

It has been known since 1990 and specifically for Systemic Scle-rosis in renal involvement since 1995 the possibility of identifying a variation of the resistivity index during illness.The study on which we want to pay attention shows an innovative and interesting correlation in the possible erectile dysfunction of the penis (ED) in patients with systemic sclerosis (SSc) about Doppler ultrasound indices of penis and kidneys and digital arteries in male with systemic sclerosis (11).Already the authors have reported a limit and an opening to a possible deepening for a study with more extensive case studies and the deepening with the pharmaco stimulation to evaluate veno-occlusive function. We would like to introduce a reflection on these investigations in addition to the problems of concurrent erectile dysfunctions because all the diseases that see an implication of the male genital sphere in primis are generally difficult to investigate for intercurrent psycho-sociological problems (15). Well-explored and well defined is the damage that involves the vascular trophism of the hand and fingers.The article is about five years ago but the argument for the de-licacy and complexity of collecting and correlating the laboratory, imaging data and the evolution of the disease at the level of life in the private sphere has a character of current interest. While we congra-tulate the courage, we think it is important to increase these studies, especially because the SSc is still highly disabling and ED related are poorly understood.
