Background: For kidney transplant patients, incisional hernia (IH) is a major complication resulting from prolonged pretransplant dialysis, immunosuppressive drugs, and the high prevalence of diabetes. However, there have been relatively few studies of IH after kidney transplantation (KT) in Japan and in the greater Asian population. Additionally, operative methods for IH repair have not been established. Methods: We retrospectively analyzed 465 consecutive patients who underwent KT at our hospital from April 2013 to March 2019. Patients who underwent incisional hernia repair were included in this study, and the follow-up time was extended to September 2020. We defined severe IH as an IH requiring surgical repair. We examine the risk factors for severe IH among KT patients and also discuss the operative methods of IH repair. Results: During the study period, 7 patients developed severe IH after KT. The cumulative occurrence rate for severe IH was 1.1% 1 year postoperatively. Multivariate logistic regression analyses showed that age at KT and dialysis duration (hazard ratio = 1.112, P = .016; hazard ratio = 1.106, respectively; P = .038) were independent risk factors for severe IH. We used polypropylene mesh for IH repair in all cases, with onlay repair performed in 5 of 7 cases. There was no recurrence or infection after mesh repair during follow-up. Conclusions: In this study, age at KT and dialysis duration were independent risk factors for severe IH in the Japanese population. Onlay repair with a polypropylene mesh appeared to be a safe and acceptable operation for IH repair after KT.
