Bladder Irrigation Guideline Summary

Introduction to Bladder Irrigation

• The Infectious Diseases Society of America explicitly recommends against routine catheter irrigation with antimicrobials or other agents to reduce catheter-associated bacteriuria or UTI in patients with long-term indwelling catheterization 1, 2

Standard Bladder Irrigation Recommendations

• Sterile normal saline is the standard irrigation solution for continuous bladder irrigation through 3-way Foley catheters 3
• Room temperature or body temperature saline is preferred over cold water for patient comfort 3

Indications for Bladder Irrigation

• Active hematuria following urological procedures to prevent catheter obstruction from blood clots 3
• Persistent visible hematuria in the drainage bag 3
• Catheter blockage from urease-producing organisms, particularly Proteus mirabilis 3

Critical Pitfalls to Avoid

• Do not irrigate catheters routinely to prevent infection, as this practice does not reduce catheter-associated bacteriuria or UTI 1, 2, 3
• Do not add antimicrobials or antiseptics to irrigation solutions as routine practice in long-term catheterization 3
• Do not use antiseptic irrigation solutions (chlorhexidine, povidone-iodine) outside of short-term perioperative surgical contexts 3

Alternative Evidence-Based Approaches for Bleeding

• Continuous bladder irrigation with normal saline remains the standard approach for managing post-procedural hematuria 3
• Remove or replace catheters as soon as clinically possible, as duration is the most important risk factor for complications 3, 4
