Prevalence of erectile dysfunction and its association with residual renal function in Chinese peritoneal dialysis patients.

Objectives: The study was to investigate the prevalence and associated factors of erectile dysfunction (ED) in peritoneal dialysis (PD) patients.
Methods: This was a cross-sectional survey. Eligible patients were interviewed by questionnaire: the five-item version of International Index of Erectile Function. Residual renal function (RRF) was assessed by daily urine volume and residual glomerular filtration rate.
Results: Totally, 176 male prevalent PD patients were interviewed, six of them were not included in analysis for sexually inactive unrelated to ED. The prevalence of ED was 80.6 %. After adjusting for confounding factors, advance age (P = 0.014), less daily urine volume (P = 0.032) and higher high-sensitivity C-reactive protein (hs-CRP) (P = 0.043) were independent risk factors for the development of ED.
Conclusion: The prevalence of ED was high in Chinese PD patients. Advanced age, poor RRF and higher hs-CRP were independently associated with the prevalence of ED.
