Suprapubic Catheter Removal & Tract Closure Guidelines

1. Timing of Removal & Expected Tract Closure

Catheters in place < 2 weeks – Deflate the balloon and remove the catheter; the suprapubic tract normally closes spontaneously within hours to 1–2 days without surgical intervention. [Guideline] [@1]
Catheters in place ≥ 2 weeks – After balloon deflation and removal, most mature tracts close spontaneously within 24–48 hours; however, if closure fails after 48–72 hours or a recent infection is present, formal layered surgical closure should be considered. [Guideline] [@1]

Apply a sterile gauze dressing to the suprapubic site immediately after catheter removal. [Guideline] [@1]
Confirm the patient can void spontaneously (or arrange alternative drainage such as intermittent catheterisation or a temporary urethral catheter) before removal to avoid post‑removal urinary retention. [Guideline] [@1]

Obtain a urine culture 24–48 hours before planned removal when infection is suspected in long‑standing catheters. [Guideline] [@4]
Treat only symptomatic urinary‑tract infection (fever ≥ 38 °C, suprapubic pain, systemic signs) with culture‑directed antibiotics before elective removal; asymptomatic bacteriuria should not be screened or treated. [Guideline] [@2]

Antimicrobial therapy at removal is therapeutic rather than prophylactic because prolonged catheterisation usually leads to colonisation. [Guideline] [@4]
Two options: (a) administer culture‑directed antibiotics based on the pre‑removal urine culture, or (b) give empirical antimicrobial therapy at the time of removal. [Guideline] [@4]
Therapeutic course duration generally ranges from 24 hours to 7 days, tailored to host factors, catheterisation duration, and infection morbidity. [Guideline] [@5]
Prophylactic antibiotics should not exceed 24 hours when no colonisation or infection is documented. [Guideline] [@4]

Persistent urinary leakage from the suprapubic site beyond 48–72 hours after removal. [Guideline] [@1]
Large‑bore (> 30 French) or long‑standing (> 6 months) tracts that fail conservative management. [Guideline] [@1]
Patient preference for immediate definitive closure. [Guideline] [@1]

Excise the epithelialised tract down to the bladder wall. [Guideline] [@1]
Close the bladder defect in two layers using absorbable sutures (e.g., 2‑0 or 3‑0 polyglycolic acid). [Guideline] [@1]
Reapproximate the rectus fascia with interrupted or running absorbable sutures. [Guideline] [@1]
Close skin and subcutaneous tissue in the usual fashion. [Guideline] [@1]
Leave a urethral or new suprapubic catheter in place for 7–10 days to permit bladder healing. [Guideline] [@1]

Inspect the suprapubic site daily for persistent leakage, erythema, or purulent discharge. [Guideline] [@6]
Monitor voiding function to ensure adequate bladder emptying and detect retention early. [Guideline] [@1]
Watch for signs of urinary‑tract infection (fever, dysuria, suprapubic pain) during the first week after removal. [Guideline] [@2]
If the tract remains open after 72 hours or significant leakage persists, arrange referral for surgical closure. [Guideline] [@1]
