Interactive Decision Tree
Algorithm Steps
- ▶Start
Acute Urinary Retention
Sudden inability to void with painful bladder distension
- ●Action
Initial Assessment
Confirm diagnosis and identify cause
- Confirm distended, palpable bladder
- Time since last void
- Pain level assessment
- History: BPH, stricture, prior retention
- Medications: anticholinergics, opioids, antihistamines
- Recent surgery/anesthesia
- ◆Decision
Signs of UTI/Urosepsis?
Fever, dysuria, bacteriuria
- ⚠Warning
⚠️ Emergent Decompression
UTI + obstruction = urosepsis risk
- Immediate catheterization
- Blood/urine cultures
- IV antibiotics
- Monitor for sepsis
- ●Action
Urethral Catheterization
16 Fr Foley catheter with 5-10mL balloon
- Standard 16 Fr Foley first attempt
- Generous lubrication (lidocaine gel)
- Inflate 5-10mL balloon once urine flows
- Document volume drained
- Rapid complete drainage is safe
- ◆Decision
Catheter Passes Easily?
Any resistance or difficulty?
- ●Action
Post-Drainage Management
Address underlying cause
- Document volume drained
- UA + culture
- BMP (check creatinine)
- Start alpha-blocker (tamsulosin 0.4mg daily)
- 5-alpha reductase inhibitor if prostate enlarged
- ●Action
Evaluate Underlying Cause
Determine etiology of retention
- BPH (most common in older men)
- Urethral stricture
- Medication-induced
- Constipation/fecal impaction
- Neurogenic (diabetes, spinal cord)
- Post-operative (anesthesia, pain meds)
- ●Action
Plan Voiding Trial
After 72h alpha-blocker therapy
- Remove catheter in AM
- Fill bladder to 300mL or as tolerated
- Check post-void residual
- Success: PVR <200mL
- Failure: PVR >400mL or unable to void
- 23-40% void spontaneously within 72h
- ◆Decision
Voiding Trial Successful?
Able to void with low PVR
- ✓Outcome
Successful Voiding
Continue alpha-blocker, urology follow-up
- Continue tamsulosin
- Urology follow-up in 2-4 weeks
- Monitor for recurrence
- Consider TURP if recurrent
- ✓Outcome
Failed Voiding Trial
Recatheterize, plan intervention
- Recatheterize
- AUA: Require 2 failed voiding trials before surgery
- Consider clean intermittent catheterization
- Urology referral for TURP or other intervention
- Long-term catheter if not surgical candidate
- ●Action
Difficult Catheterization
Stepwise approach for difficult cases
- Try coude tip catheter (for BPH)
- Urology consult
- Flexible cystoscopy + guidewire
- Council catheter over wire
- Suprapubic catheter if urethra impassable
- ●Action
Suprapubic Catheterization
If urethral access impossible
- Ultrasound guidance preferred
- Confirm distended bladder on imaging
- Contraindicated if bladder not distended
- Caution if prior lower abdominal surgery
- Use SPC kit or needle aspiration

Individual patient factors may require deviation from these recommendations.
Known Limitations
- Does not address pediatric urinary retention
- Neurogenic bladder requires specialized management
- Does not fully address female-specific causes
- Chronic retention may require different approach
- Does not address post-operative retention in detail
