Catheter Management After Open VVF Repair

Catheter Duration Recommendations

Remove catheters at 14 days post-operatively for uncomplicated bladder injuries and VVF repairs, as this timeframe allows adequate healing in most cases 1
2-3 weeks is the standard duration for extraperitoneal bladder injuries managed with catheter drainage, as most uncomplicated injuries heal within this timeframe 1
Consider extending catheter drainage beyond 4 weeks only for non-healing bladder injuries unresponsive to standard catheter drainage, at which point strong consideration for open repair becomes appropriate 1

The main risk factor for catheter-associated infections is the length of time the device remains in place 2, 3
Periodically reassess the need for catheters to determine whether removal is possible, as this is the best approach to prevent infections 2, 3
Consider prophylactic antimicrobials covering uropathogens, which can reduce serious postprocedural sepsis-related complications from 50% to 9% 2

Dual drainage systems ensure adequate decompression and prevent tension on the repair site when bladder bivalving is performed 2
Both catheters should remain in place for the same duration to maintain continuous, low-pressure bladder drainage 1
Perform follow-up cystography to confirm healing before catheter removal after treatment with catheter drainage 1
If healing is incomplete at 14 days, extend drainage and repeat imaging at weekly intervals 2

Do not routinely extend catheter duration beyond 3 weeks without documented evidence of incomplete healing, as prolonged catheterization increases infection risk, especially in HIV-positive patients 1, 2
Do not use routine prophylactic antibiotics throughout the entire catheter duration unless specifically indicated by patient risk factors or documented infection 4
