Abstract

Our goal is to evaluate the association between histopathology of glomerulosclerosis (GS) and atherosclerosis (AS) in the nephrectomized normal parenchyma together with patients’ background, and erectile dysfunction (ED) of patients treated with radical nephrectomy (RN) for renal cell carcinoma (RCC). ED was assessed with the International Index of Erectile Function in 65 patients who were less than age 70 years at the time of questionnaire. Glomeruli status was assessed by the extent of global GS. AS was graded based on lumen occlusion and frequency of involvement. Patients’ backgrounds included any comorbidities, post-RN renal insufficiency, tumor pathology, demographics and social status. The presence of diabetes mellitus and lack of a spouse were independent predictors for severe ED, whereas G0/1 AS was an independent predictor for mild/no ED. The extent of global GS was significantly lower in patients with mild/no ED than in other patients. Our study represents the first report identifying healthy arterial status in the renal parenchyma as a significant indicator of favorable erectile function and that the evaluation of AS severity is not a superior indicator of severe ED in the presence of comorbidities or social status among patients treated with RN.
