title: Atherosclerosis as a predictor of delayed recovery from lower urinary tract dysfunction after robot-assisted laparoscopic radical prostatectomy.
abstract: The aim of the present study was to investigate whether atherosclerosis could be associated with lower urinary tract dysfunction in the early postoperative period after robot-assisted laparoscopic radical prostatectomy (RARP).
  
  
  
  Eighty consecutive patients undergoing RARP were investigated. The severity of atherosclerosis was evaluated by the cardio-ankle vascular index (CAVI) before RARP. Patients were divided into two groups, the atherosclerotic group (CAVI ≥9.0) and the control group (CAVI <9.0). International Prostate Symptom Score (IPSS), quality of life (QOL) index, uroflowmetry, post-void residual urine volume (PVR), frequency-volume charts, and the 1-hr pad test were compared between the two groups. Assessments were performed before RARP, and then at 1, 3, and 6 months after RARP.
  
  
  
  Preoperative subjective and objective parameters were not significantly different between the two groups. The voiding symptom score of the IPSS and the QOL index was significantly higher in the atherosclerotic group at 3 months after RARP (P = 0.035, P = 0.001, respectively). The maximum flow rate was consistently lower in the atherosclerotic group, reaching a significant difference at 6 months after RARP (P = 0.027). IPSS total and storage symptom scores, PVR, frequency, and urine loss were not significantly different between the groups after RARP.
  
  
  
  Atherosclerosis delayed the improvement of both voiding symptoms and voiding function after RARP, leading to aggravation of QOL in the early postoperative period. Atherosclerosis may be a predictor of slower recovery from transient lower urinary tract dysfunction immediately after RARP. Neurourol. Urodynam. 35:920-925, 2016. © 2015 Wiley Periodicals, Inc.
