Introduction:
To evaluate the incidence and risk factors for postoperative inguinal hernia (IH) after robot-assisted radical prostatectomy (RARP) and to assess whether a newly developed prevention technique reduces the incidence of IH after RARP.
Methods:
We included 161 consecutive patients (322 groins) who underwent RARP between September 2011 and October 2013. The prevention technique was as follows: (1) sufficient incision of peritoneum around the internal inguinal ring; (2) separation of spermatic vessels; (3) dissection of vas deferens.
Results:
Postoperative IH occurred in 14 cases (19.4%) occurring in the observation group compared to 2 cases (2.2%) in the prevention group. Patent processus vaginalis (PPV) was the only risk factor. Time-to-event analysis demonstrated a significant decrease in IH incidence in the IH prevention group (p = 0.005).
Conclusion:
Our data reveal a higher incidence of IH after RARP, with the existence of PPV as the only identified risk factor. Our simple IH-prevention technique, which does not involve the use of artificial materials, appears safe and effective.
