RESUMO
Despite the benefits of using surgical meshes to repair abdominal and inguinal hernias, there are increasing reports of mesh migration into the gastrointestinal and urinary tracts-a complication that cannot be overlooked or neglected. Resolution of such cases can be difficult and depends on the degree of migration and the anatomical site involved. The present paper reports the case of a 68-year-old patient undergoing a trans-ureteral resection of a possible bladder malignancy diagnosed following clinical and radiological evaluation. During the procedure (cytoscopy), it was found that migration of a mesh was mimicking the urological disease initially suspected. A polypropylene mesh had been inserted into the right inguinal region 20 years previously to repair an inguinal hernia. This is one of only a few case reports on mesh migration presenting as a suspected bladder malignancy.
