Chapter 26 · Acute lower urinary tract conditions
Clot retention
Definition
Clot retention is the accumulation of blood clots in the bladder, impairing urinary drainage.
Causes: tumor bleeding, bleeding after TURP, trauma, anticoagulants.
Clinical assessment
- Pain, vesical tenesmus.
- Inability to void or passage of blood with small clots.
- Signs of hypovolemia in massive blood loss.
Diagnosis
- Ultrasonography: clots, distended bladder.
- Hemoglobin, hematocrit.
- Coagulation profile, review of anticoagulants.
Emergency management
- Large-bore three-way catheter (22–24 Ch).
- Clot evacuation by irrigation with sterile solution (normal saline) using a Janet syringe.
- Continuous irrigation if bleeding persists.
- If unsuccessful, perform cystoscopy with clot evacuation and hemostasis (electrocoagulation, laser).
- In massive bleeding, activate the approved major hemorrhage and transfusion protocol; involve an anesthesiologist/intensivist and the transfusion service. Document indications, patient and blood component identification, compatibility, timing, monitoring, and reactions.
After bleeding has stopped
- Monitor hemodynamics and hemoglobin.
- Assess the cause of bleeding.
- Plan definitive treatment (tumor, prostate, coagulopathy).
Algorithm
| Step | Action |
|---|---|
| 1 | Assess hemodynamics, Hb, and coagulation |
| 2 | Large-bore three-way catheter |
| 3 | Clot evacuation (irrigation) |
| 4 | Continuous irrigation for ongoing bleeding |
| 5 | If unsuccessful → cystoscopy + hemostasis |
| 6 | Source control; for massive bleeding, follow the local transfusion and coagulopathy correction protocol |
