Insights
Urokinase effectively cleared clots in two of three patients with obstructed urinary catheters. This therapy shows promise for coagulated catheters unresponsive to other treatments.
Area of Science:
- Urology
- Nephrology
- Pharmacology
Background:
- Urinary catheter obstruction by clots is a common clinical challenge.
- Existing treatments for coagulated catheters may be ineffective.
- Urokinase is a thrombolytic agent with potential applications in urinary tract interventions.
Observation:
- Three cases of urinary catheter obstruction due to clots were reviewed.
- Patients included metastatic breast carcinoma, renal trauma, and benign ureteric obstruction.
- Urokinase instillation was administered to all three patients.
Findings:
- Two of the three patients experienced adequate clot resolution after urokinase instillation.
- One patient with benign ureteric obstruction and sepsis did not respond to urokinase.
- Urokinase was generally well-tolerated in the treated patients.
Implications:
- Urokinase may be a viable therapeutic option for managing coagulated urinary catheters.
- Further investigation is warranted to determine optimal urokinase protocols for catheter clearance.
- This approach could offer an alternative for patients with refractory catheter obstruction.
Objective:
The objective of thisstudy is to review three cases using urokinase in patientswith urinary catheter obstructed by clots, aswell to carry out a review of the published literature. METHODS: It was done a review of three casesfrom 2019 to 2020 who required urokinase due tourinary catheters obstructed by clots in our department.In addition, a reference search was performedin Pubmed. RESULTS: The first case was a woman with metastaticbreast carcinoma who required nephrostomyplacement. The second case was a renal trauma thatrequired bladder catheterization. The third case wasa male with a benign ureteric obstruction who requirednephrostomy placement due to sepsis. After instillationswith urokinase, the first two cases respondedadequately, while the third was unsuccessful. CONCLUSIONS: Urokinase may be an effectiveand well-tolerated therapy in the treatment of coagulatedurinary catheters that does not respond toother measures.
