Urothelial carcinoma of the urinary bladder related to a migrated mesh after inguinal hernioplasty: A case report

INTRODUCTION: Mesh migration into the urinary bladder following repair of inguinal hernia and bladder cancer caused by a foreign body are extremely rare. We hereby report a rare case of urothelial carcinoma of the bladder related to a migrated mesh following inguinal hernioplasty. CASE PRESENTATION: A 70‐year‐old Japanese woman who underwent surgery for left inguinal hernia 5 years previously presented with gross hematuria. Cystoscopy and computed tomography revealed stone formed in the mesh migrated into the urinary bladder. Mesh removal surgery and partial cystectomy were performed; and pathological findings revealed muscle invasive bladder cancer. Neoadjuvant chemotherapy and radical cystectomy were performed. The pathological diagnosis was high‐grade urothelial carcinoma, stage pT3a with positive lymph nodes, stage pN3. To date, 3 months after surgery, the patient has received adjuvant chemotherapy. CONCLUSION: To our knowledge, this is the first report of urothelial carcinoma related to a migrated mesh after inguinal hernioplasty.
