The decision to use mesh or not is a complex one with doctors on both sides of this issue.
Complications associated with the placement of vaginal mesh are well know and the discussion of those risk are part of the informed consent. Depending on what mesh is used, absorbable or non absorbable, and where and how the mesh is placed, anterior vaginal wall ( under the bladder), posterior vaginal wall (over the rectum), place abdominally or vaginally, will affect the complication rate.
In general, patients and doctors are worried about infection, mesh exposure, mesh erosion, and pain associated with the use of mesh.
Infection is generally rare but serious if occurs. The mesh must be removed if infection occurs.
Mesh exposure is where the mesh is visible usually in the vagina and is often a minor complication that can be handled in an office setting. Treatment with topical estrogen and trimming of the exposed mesh often is all that is necessary.
Mesh erosion implies that the mesh has eroded into or through an area. This can be serious depending on what is involved in the erosion. Often these need to be surgically removed.
It should be noted that many times mesh exposure and erosion are used interchangeably.
Pain associated with mesh placement does occur, primarily pain with intercourse, and my require treatment.
The internet is a poor source for statistics regarding mesh complications and the medical literature is complex. Reports of Erosion vary from a low of less than 1% to as high as 25% or more.
Given your surgeon does not believe in the use of mesh, you might get a second opinion from one that does use mesh. He or she should be able to provide you with their own percentages of complications and discuss the pros and cons of mesh use.
Sincere thanks for an excellent answer covering both sides of the mesh issue.
