Algorithm Steps

  1. Start

    Acute Urinary Retention

    Sudden inability to void with painful bladder distension

    1. 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
      1. Decision

        Signs of UTI/Urosepsis?

        Fever, dysuria, bacteriuria

        1. Warning

          ⚠️ Emergent Decompression

          UTI + obstruction = urosepsis risk

          • Immediate catheterization
          • Blood/urine cultures
          • IV antibiotics
          • Monitor for sepsis
          1. 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
            1. Decision

              Catheter Passes Easily?

              Any resistance or difficulty?

              1. 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
                1. 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)
                  1. 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
                    1. Decision

                      Voiding Trial Successful?

                      Able to void with low PVR

                      1. 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
                      2. 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
              2. 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
                1. 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
