title: Evaluation of Results of Diagnostic Ureteroscopy in Chronic Hemodialysis Patients.
abstract: OBJECTIVE
  To investigate the safety of diagnostic ureteroscopy (dURS) in chronic hemodialysis patients.
  
  
  METHODS
  The data of chronic hemodialysis patients (group I) and the patients with normal estimated glomerular filtration rate (eGFR) (group II) who had dURS between 2004 and 2014 were analyzed retrospectively. eGFR, complications, and postoperative stent placement were noted in all patients. Continuous and categorical variables were compared between the groups. p < 0.05 was considered as statistically significant.
  
  
  RESULTS
  Overall complication rate of group I was 10.5%, while this rate was 4.8% in group II (p = 0.16). No statistically significant differences were noted in terms of gender, age, or laterality between two groups. The mean duration of surgery and the rates of balloon dilatation and postoperative stent placement were higher in group I when compared with group II, and differences were statistically significant (p < 0.05).
  
  
  CONCLUSIONS
  In this study, we determined that dURS was a safe method in chronic hemodialysis patients. However, duration of surgery and the rates of balloon dilatation and postoperative stent placement were high in our study.
