OBJECTIVES: To determine the significant independent predictors of inguinal hernia development after radical prostatectomy (RP) so that prophylactic measures can be undertaken in those at increased risk. Although inguinal hernia is a recognized complication after RP, the risk factors have not been well elucidated. METHODS: From January 1999 to June 2007, 4592 consecutive patients underwent open retropubic RP or laparoscopic RP without previous radiotherapy. The median follow-up was 36.9 months (interquartile range 20.3, 60.6). Comorbidities were recorded, as well as the occurrence of inguinal hernia, wound infection, and bladder neck contracture. Cox proportional hazards analysis was performed for the predictors of inguinal hernia after RP on multivariate analysis. RESULTS: Inguinal hernia developed after RP in 68 men (1.5%) men at a median follow-up of 7.9 months (interquartile range 4.3, 18.1). The laterality was bilateral in 7, right in 27, left in 24, and not documented in 10 patients. The significant independent predictors of inguinal hernia included age (hazard ratio [HR] 1.05, 95% confidence interval [CI] 1.01-1.09, P = .016), body mass index (HR 0.91, 95% CI 0.85-0.98, P = .011), history of inguinal hernia repair (HR 3.9, 95% CI 1.8-8.2, P <.001), and bladder neck contracture (HR 2.8, 95% CI 1.3-5.9, P = .007) but not the RP approach (HR 1.08, 95% CI 0.60-1.96, P = .80 for laparoscopic RP vs retropubic RP). CONCLUSIONS: The results of our study have indicated that older patients, thinner patients, those with previous inguinal hernia repair, and those developing bladder neck contracture are at increased risk of developing an inguinal hernia. These factors might identify a subset for whom evaluation for subclinical hernia might allow prophylactic inguinal hernia repair at RP.
