Repair of Inguinal Bladder Hernias Concomitant with Localized Prostate Cancer: A Case Report and Review of the Literature

Abstract

This study reports two rare cases of inguinal bladder hernias accompanied by localized prostate cancers. They were treated with simultaneous repair of inguinal bladder hernias and open retropubic radical prostatectomy. Additionally, we performed a literature review on previous inguinal bladder hernias case reports. In this present study, the first patient was a 64-year-old man histopathologically diagnosed with prostate cancer; computed tomography for staging of prostate cancer revealed a “Pelvic Mickey Mouse Sign.” The second patient was a 75-year-old man with right inguinal swelling that gradually increased in size for 30 years. He was referred to our department due to nocturia and urge incontinence. His prostate-specific antigen level was 4.17 ng/mL, and a transrectal prostate biopsy revealed prostate cancer. Preoperative imaging studies revealed a right hernia wherein most of the bladder slid beyond the inguinal channel filling the scrotum. Both patients underwent the Lichtenstein technique for inguinal bladder hernias simultaneously with retropubic radical prostatectomy using separate surgical incisions to avoid urinary contamination of the mesh. In our comprehensive review of patients who underwent inguinal bladder hernias surgical repair, there were 51 cases (50 males and 1 female). The mean patient age was $60.6\pm 12.3$ years. Five cases demonstrating concomitant prostate cancer were observed. This present case report is the first to describe two patients who underwent surgeries for the simultaneous repair of inguinal bladder hernias and retropubic radical prostatectomy with separate surgical incisions. Supposedly, this simultaneous approach is suitable for concomitant inguinal bladder hernias and prostate cancer treatment.
