Summary
The catalase test offers a rapid, objective method to assess bladder irrigation effectiveness after surgery. This simple test helps optimize irrigation, reducing unnecessary procedures and improving patient outcomes.
Area of Science:
- Urology
- Biochemistry
- Surgical Innovation
Background:
- Post-operative bladder irrigation is crucial after prostate, bladder, and urethral surgeries.
- Assessing irrigation efficiency objectively and rapidly remains a clinical challenge.
Purpose of the Study:
- To introduce and evaluate the catalase test for real-time monitoring of bladder irrigation efficacy.
- To determine if the catalase test can guide adjustments in irrigation protocols.
Main Methods:
- A rapid catalase test using hydrogen peroxide and patient lavage fluid.
- Collection of 3 ml irrigation fluid mixed with 0.5 ml 3% hydrogen peroxide.
- Observation for gas bubbles and foam indicating catalase presence (from erythrocytes, leukocytes, bacteria).
Main Results:
- The catalase test provides a clear positive (bubbles/foam) or negative result.
- Three degrees of positive results were defined to quantify catalase levels.
- Clinical trials in 20 patients demonstrated good results, allowing for irrigation adjustments.
Conclusions:
- The catalase test is a viable, objective, and rapid method for evaluating post-operative bladder irrigation.
- Test results enable dynamic regulation of irrigation rate and volume, potentially replacing constant perfusion.
- Negative test results can safely discontinue irrigation, optimizing patient care.
