Vaginal mesh contraction: definition, clinical presentation, and management

Area of Science:

• Urogynecology
• Pelvic reconstructive surgery
• Biomaterials science

Background:

• Transvaginal polypropylene mesh is widely used for pelvic organ prolapse (POP) repair.
• Mesh contraction is a recognized complication leading to patient morbidity.

Purpose of the Study:

• To define the clinical entity of vaginal mesh contraction.
• To evaluate the outcomes of surgical intervention for symptomatic mesh contraction.

Main Methods:

• Case series of 17 women undergoing surgical intervention for symptomatic vaginal mesh contraction.
• Evaluation of presenting symptoms, examination findings, management, and outcomes.
• Surgical intervention involved mesh mobilization, division of fixation arms, and excision of contracted mesh.

Main Results:

• Common symptoms included severe vaginal pain, dyspareunia, and focal tenderness.
• Associated findings were mesh erosion, vaginal tightness, and shortening.
• Post-surgery, 88% experienced reduced vaginal pain and 64% reduced dyspareunia.
• Three women required complete mesh excision due to persistent symptoms.

Conclusions:

• Vaginal mesh contraction is a significant complication of polypropylene mesh repair for POP.
• It is associated with substantial morbidity and often necessitates surgical intervention.
• Development of novel graft materials with reduced shrinkage properties is critical.
