Mesh Migration Into Urinary Bladder After Open Ventral Herniorrhaphy With Mesh: A Case Report

Ventral hernia repair with mesh products is of increasing popularity. The long-term results of mesh repair of ventral hernia are superior to primary suture repair. However, occasional complications may still present. We report on a 77-year-old man who underwent ventral hernia repair with a mesh 5 years ago with complication of mesh migration into the urinary bladder and enterovesical fistula. The patient presented with lower urinary tract symptoms initially. By urinalysis, persistent hematuria and pyuria were found after antibiotic treatment. For further investigation of hematuria, intravenous urography was performed, which revealed a faint radio-opaque patch at the right pelvis. To obtain a more precise relationship between the lesion and the adjacent organs, computed tomography and cystoscopy were arranged. They confirmed a mesh with stone formation in the urinary bladder. To remove the mesh, segmental resection of the ileum and cystorrhaphy were performed.Key words: Incisional hernia, Surgical mesh, Complications, Urinary Bladder CalculiPrimary repair of ventral hernia with component separation is still the major repair method. There is increasing popularity of ventral hernia repair with mesh products. The long-term results of mesh repair of ventral hernia are superior to primary suture repair.^1,2 However, occasional complications may still occur. Mesh migration to adjacent organs is one of the complications. It has been reported in some patients with a surgical history of either open or laparoscopic herniorrhaphy with mesh.^3–8 In this case report, a 77-year-old man, who underwent ventral hernia repair with mesh before, had the complication of mesh migration into the urinary bladder and enterovesical fistula with the initial presentation of lower urinary tract symptoms.
