Abstract
To determine causative factors for de novo inguinal hernia (IH), after robot-assisted radical prostatectomy (RARP). This was a retrospective, single-center study, which included patients undergoing RARP for prostate cancer at our institution, from February 2012 to January 2015. Cox proportional hazards models were used to determine the relationships between de novo IH and various factors. A total of 284 patients were included in the analysis. Forty-two (14.7%) patients developed IH at a median period of 8 months after RARP. On multivariate analysis, preoperative international prostate symptom score question 6 > 2, and a patent processus vaginalis were significantly correlated with de novo IH (hazard ratio (HR) 4.17, 95% confidence interval (CI) 2.07–8.37, p < 0.001; HR 3.67, 95% CI 2.36–5.69, p < 0.001). Preoperative urinary straining and a patent processus vaginalis were predictive of de novo IH after RARP.
