Clinical characteristics of patients with inguinal hernia mesh migration into the bladder

Abstract

Introduction: We report two cases of mesh migration into the bladder after inguinal hernia surgery. Case presentation: In the first case, a 48-year-old woman who underwent right internal inguinal hernia repair, 18 months prior, presented with pollakiuria and microscopic hematuria that was resistant to antibiotics. A submucosal tumor was detected at the bladder dome by cystoscopy, and transurethral resection was performed. Intraoperatively, a migrated mesh was observed in the submucosal lesion. In the second case, a 55-year-old man who underwent a right external inguinal hernia repair, approximately 14 years prior, presented with persistent microscopic hematuria and pyuria. Cystoscopy revealed mesh migration to the upper right bladder wall. Both patients underwent partial cystectomy with mesh removal, and their complaints were resolved after surgery. Conclusion: Mesh migration should be suspected in patients with a history of inguinal hernia repair, accompanied by persistent lower urinary tract symptoms or abnormal urinalysis findings.
