title: Prevalence of erectile dysfunction and its association with residual renal function in Chinese peritoneal dialysis patients.
abstract: OBJECTIVE
  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.
  
  
  CONCLUSIONS
  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.
