Urinary symptoms must be frequent in Scleroderma. In one hand, mobility limitation by joint stiffness and skin sclerosis, forced diuresis due to heart involvement (cardiomyopathy or pulmonary hypertension), diuretics use and corticoid-induced hyperglycaemia, as well as narcotic medication use, puts patients at higher risk of secondary bladder filling and voiding dysfunction. In another hand, few case report and small sample observational studies have identified a specific sclerosis of the urinary tract. Those two mechanisms must be more frequent in the diffuse cutaneous form of scleroderma (dcSSc) compare to the limited one (lcSSc). But prevalence or incidence is unknown.
