We read with great interest the article “Mesh erosion into urinary bladder, rare condition but important to know” by Li and Cheng [1]. We completely agree with the authors when they conclude that mesh migration or erosion into urinary bladder, even if rarely reported, is a major complication that can occur after both open and laparoscopic inguinal hernia repair in a wide range of latent period. We recently performed a systematic review of all cases of mesh related visceral complications (MRVCs) reported between 1992 and 2018 in literature, identifying 97 events [2].

The use of meshes in inguinal hernia repair (IHR) has gained popularity but new complications have been observed. Meshrelated
visceral complications (MRVCs) are generally considered rare and hence are not studied in depth. We carried out a
thorough literature search and collected 101 clinical reports published from 1992 to 2018. The reported complications seem
to have tripled in the last decade. Ninety-seven cases met the inclusion criteria and they were subdivided into four groups
