Indications for 3-Way Bladder Catheter
A 3-way bladder catheter is indicated for continuous bladder irrigation (CBI) to prevent or manage blood clots in patients with moderate to severe gross hematuria, most commonly following urologic procedures such as transurethral resection of the prostate (TURP), transurethral resection of the bladder (TURB), or open prostatectomy. 1, 2
Primary Clinical Indications
Post-Surgical Hematuria Management
- The most common indication is for continuous bladder irrigation following TURP, TURB, or open prostatectomy to prevent catheter obstruction from blood clots 1, 2
- Routine continuous bladder irrigation after TURP significantly reduces catheter obstruction rates (4.4% vs 12.9% when irrigation is used selectively, p<0.001) 2
- The system allows simultaneous irrigation through one port while draining through another, maintaining continuous flow to prevent clot formation 1, 3
Severe Bladder or Prostatic Hemorrhage
- Indicated when bladder irrigation through a 3-way catheter is the first-line intervention for intractable hematuria from various causes including radiation cystitis, bladder carcinoma, cyclophosphamide-induced cystitis, severe infection, or prostate cancer 4
- Used when hematuria is severe enough to risk clot retention and bladder outlet obstruction 1, 4
Technical Considerations for Optimal Function
Catheter Selection
- For optimal continuous bladder irrigation, use a 22F or 24F catheter, as these sizes provide the best balance of irrigation and drainage flow rates 3, 5
- The Bardex 22F and 24F catheters demonstrated superior continuous irrigation flow (1.6-1.7 mL/s) compared to other brands tested 3
- The Rusch Simplastic 24F catheter showed the highest irrigation rates (average 4.6 mL/s) in comparative studies 5
System Setup
- The irrigation bag should be suspended 80 cm above the catheter level to optimize gravity-dependent flow 1
- A closed system must be maintained to reduce infection risk 6
- Enhanced pressure systems using a sphygmomanometer bulb can increase flow rates and improve clot clearance (99.5% success rate in preventing clot retention) 1
When 3-Way Catheters Are NOT Appropriate
Alternative Catheter Types Preferred
- For routine bladder drainage without anticipated hematuria, a standard 2-way Foley catheter is appropriate and preferred 7
- For long-term catheterization needs without irrigation requirements, suprapubic catheterization offers lower infection rates (RR 2.60 for bacteriuria with urethral vs suprapubic) and reduced urethral complications 6, 8, 7
- For male patients requiring bladder management without irrigation needs, external condom catheters show lower rates of catheter-associated bacteriuria and UTI 6, 7
Common Pitfall to Avoid
- Do not place a 3-way catheter "just in case" irrigation might be needed later—this unnecessarily increases the catheter size and patient discomfort without clinical benefit 9
- The catheter should be removed as soon as continuous irrigation is no longer required to minimize infection risk and patient discomfort 7, 9
