The efficacy of low-dose tadalafil in patients undergoing hemodialysis with end-stage renal disease

Abstract

Background: Erectile dysfunction (ED) is a disorder that is frequently observed in people with chronic kidney disease who undergo hemodialysis (HD). In the context of evidence-based medicine, we aimed to investigate the effect of low-dose tadalafil on sexual function in patients undergoing HD. Methods: The medical records of 30 males (aged 29-65 years) with end-stage renal disease (ESRD) on a HD program, and who had received 5 mg tadalafil twice weekly, were retrospectively evaluated. Changes in erectile and ejaculatory function were evaluated using the International Erectile Function Index questionnaire, the Erection Hardness Scale (EHS), and the Male Sexual Health Questionnaire (MSHQ). Results: The mean age of the patients was 47.6 +/- 10.1 years, their mean body mass index was 24.3 +/- 4.2 kg/m(2), their mean hemoglobin was 11.9 +/- 0.9 g/dL, and their mean creatinine clearance was 5.8 +/- 1.1 mL/min. At the third month of treatment, 36.6% of the patients had no ED, 40% had mild ED, 10% had mild-to-moderate ED, and 13.3% had moderate ED. The mean MSHQ scores (p < .05) and the mean EHS scores (p = .001) were significantly improved. There was no significant difference between Beck's Depression Inventory scores (p > .05), but Hamilton anxiety rate scores decreased significantly (p = .001). The quality-of-life score improved throughout the study period (p < .05). Conclusions: Tadalafil therapy is an effective therapeutic option in patients with ESRD who undergo HD, not only for the treatment of ED, but also for ejaculatory function, with acceptable adverse effects.
