Mesh Complication Rates After Sacrocolpopexy
The incidence of mesh-related complications requiring reoperation after sacrocolpopexy is low, ranging from 0.7% to 3.5% for mesh exposure and 1.5% to 3.5% for all mesh-related complications requiring surgical intervention.
Overall Complication Rates
The most robust recent data demonstrates reassuringly low rates of mesh complications:
- Mesh exposure requiring reoperation: 0.7% to 3.5% 1, 2, 3
- Total mesh-related reoperations: 1.5% 1
- Chronic pain requiring specialist care: 3% 1
A large UK tertiary center study with nearly 10-year median follow-up (116 months) found only 1.5% of patients required reoperation for mesh-related adverse events 1. This represents one of the longest follow-up periods in the literature and provides the most reliable long-term data.
Specific Complication Types
Mesh Exposure
The vaginal mesh exposure rate is consistently reported between 0.7% and 7.3% depending on mesh type and surgical technique:
- Lightweight polypropylene mesh (28 g/m²): 7.3% total graft-related complications, with only 2.8% symptomatic 4
- Heavier-weight polypropylene mesh (>44 g/m²): 22.8% total graft-related complications, with 16.8% symptomatic 4
- Standard laparoscopic sacrocolpopexy: 0.7% vaginal mesh exposure 2
The type of mesh matters significantly—lightweight mesh demonstrates a threefold lower risk of graft-related complications compared to heavier-weight mesh (HR 3.3,95% CI 1.6-7.1) 4.
Suture-Related Issues
Non-mesh complications include 0.6% erosion of non-absorbable vaginal sutures, with half managed conservatively using topical estrogen and antibiotics 2.
Serious Complications
Rare but serious complications include:
- Bladder or bowel erosions
- Spondylodiscitis (inflammatory/infectious spinal complications)
- Mesh-related chronic pain 5
Factors Affecting Complication Rates
Protective Factors
- Obesity paradoxically reduces mesh exposure risk (OR 0.2,95% CI 0.01-0.8) 6
- Use of lightweight polypropylene mesh 4
- Delayed absorbable monofilament suture (non-inferior to permanent suture) 5
Risk Factors
- Concomitant sling procedures increase mesh exposure odds (OR 1.91,95% CI 1.28-2.83) 6
- Higher body mass index increases reoperation risk for prolapse recurrence (HR 1.136,95% CI 1.012-1.276) 3
- Heavier-weight mesh significantly increases symptomatic complications (HR 6.0,95% CI 2.5-14.3) 4
Overall Reoperation Rates
Beyond mesh-specific complications, the total reoperation rate is approximately 15% 3:
- 7.4% for stress urinary incontinence requiring mid-urethral sling
- 5.2% for prolapse recurrence
- 3.5% for mesh-related complications
Clinical Context
Most patients report sustained satisfaction—70.4% rate their prolapse symptoms as "very much better" or "much better" at long-term follow-up 1. The lifetime risk of any pelvic organ prolapse or urinary incontinence surgery is 11%, with a reoperation rate as high as 29% across all procedures 7, making sacrocolpopexy's complication profile relatively favorable.
Important Caveats
The type of concomitant hysterectomy (supracervical vs. total) does not significantly affect mesh exposure rates (0.7% vs. 0.62%, p=0.61) 6, though supracervical approach shows higher port site hernia rates (1.3% vs. 0.65%) but lower surgical site infections (0.81% vs. 1.2%) 6.
Asymptomatic mesh exposure can be managed expectantly, while symptomatic cases often require removal of entire mesh arm(s) via abdominal approach, though transvaginal or partial excision is frequently attempted first 5.
