Quick Answer
Cystoclysis generally refers to bladder irrigation, particularly continuous bladder irrigation, or CBI. During the procedure, sterile irrigation fluid enters the bladder through a urinary catheter and drains into a collection bag together with urine, blood and small clots. Cystoclysis is commonly used to help prevent or remove blood clots, maintain catheter patency and support urine drainage after selected urological procedures.
The term cystoclysis is often encountered in searches about bladder irrigation, continuous bladder irrigation and postoperative urinary care. Although terminology may vary between healthcare systems, it generally describes the introduction of an irrigation solution into the bladder through a catheter.
Bladder irrigation may be continuous, intermittent or performed manually, depending on the clinical objective, the patient’s condition and the healthcare facility’s approved protocol. The procedure should be prescribed, initiated and monitored by trained healthcare professionals.
What Is Cystoclysis?
Cystoclysis is a form of bladder irrigation in which a prescribed sterile solution is introduced into the bladder through a urinary catheter. The fluid then returns through the catheter drainage pathway, carrying urine, blood, mucus, sediment or small clots into a drainage bag.
In continuous bladder irrigation, fluid flows into and out of the bladder continuously. A three-way catheter for bladder irrigation is commonly used because it provides separate channels for:
Introducing irrigation fluid into the bladder
Draining urine and irrigation return
Inflating the catheter retention balloon
Cystoclysis is not the same as ordinary urinary catheter drainage. It adds a controlled irrigation pathway to help maintain flow when blood, clots or debris could obstruct the catheter.
Why Is Cystoclysis Performed?
The main purpose of cystoclysis is to maintain an open drainage pathway between the bladder and the urine collection system. It may be prescribed when blood, clots, mucus or other debris could interfere with urine drainage.
Common clinical objectives include:
Preventing blood clot accumulation: Irrigation may help reduce the formation or retention of clots after selected prostate, bladder or urinary tract procedures.
Removing small clots and debris: The returning irrigation fluid may carry blood, small clots, mucus and tissue debris into the drainage bag.
Maintaining catheter patency: Controlled irrigation helps reduce the risk of the catheter becoming obstructed by blood or debris.
Supporting urine drainage: Keeping the drainage pathway open allows urine and irrigation fluid to leave the bladder.
Monitoring postoperative bleeding: Healthcare professionals can observe changes in drainage colour, clot burden and fluid output.
In selected clinical situations, prescribed medications or specialised irrigation solutions may also be introduced into the bladder. The solution, concentration, volume and duration must follow the clinician’s order and institutional protocol.
What Are the Types of Bladder Irrigation?
Bladder irrigation can be divided into three main approaches. The appropriate method depends on the indication, catheter configuration, prescribed treatment and facility protocol.
| Irrigation Type | How It Works | Typical Objective |
|---|---|---|
| Continuous Bladder Irrigation | Irrigation solution flows continuously through a dedicated catheter lumen while urine and irrigation return drain through a separate lumen. | Maintain continuous drainage and help prevent clot accumulation. |
| Intermittent Bladder Irrigation | Irrigation is delivered at prescribed intervals or when clinically required rather than continuously. | Periodically flush the catheter and support catheter patency. |
| Manual Bladder Irrigation or Washout | A trained clinician manually introduces and withdraws sterile fluid using approved equipment and technique. | Clear an obstructed catheter or remove retained clots and debris. |
Continuous bladder irrigation and manual bladder washout are related but not identical procedures. For a more detailed comparison, read bladder irrigation vs bladder washout.
What Equipment Is Used for Cystoclysis?
A cystoclysis or continuous bladder irrigation system combines the irrigation-fluid pathway with a separate urine-drainage pathway. The exact components vary according to the clinical application and product configuration.
| Component | Function |
|---|---|
| Prescribed irrigation solution | Provides the fluid used to irrigate the bladder according to the clinical order. |
| Bladder irrigation set | Transfers irrigation solution from the fluid container toward the catheter through tubing and flow-control components. |
| Three-way urinary catheter | Provides separate irrigation, drainage and balloon-inflation channels. |
| Urine drainage bag | Collects urine, irrigation fluid, blood and small amounts of debris returning from the bladder. |
| Supporting and monitoring equipment | Supports the irrigation containers and helps staff document irrigation input, drainage output and patient observations. |
The bladder irrigation set and the catheter perform different but connected functions. The irrigation set carries fluid from the container, while the catheter provides the patient-side irrigation and drainage channels.
Connector configuration, tubing length, inlet arrangement, flow-control components and drainage compatibility should be confirmed against the product specifications and the healthcare facility’s approved protocol. More information about the fluid pathway is available in our guide to bladder irrigation tubing.
How Does the Cystoclysis Procedure Work?
The exact cystoclysis procedure varies according to the clinical indication, catheter type, prescribed solution and local protocol. At a general level, continuous bladder irrigation involves the following stages:
Clinical assessment and prescription: The healthcare team confirms the indication, irrigation solution, catheter requirements and monitoring plan.
Equipment preparation: The prescribed solution, irrigation set, catheter, drainage system and supporting equipment are prepared using the required infection-control technique.
System connection: The irrigation tubing is primed according to the applicable instructions and connected to the correct irrigation lumen of the catheter.
Irrigation initiation: Fluid delivery is started at the prescribed rate while confirming that return fluid is draining through the catheter into the collection bag.
Ongoing monitoring: Staff observe drainage colour, clot burden, inflow, outflow, catheter patency, patient comfort and signs of leakage or poor drainage.
Adjustment or discontinuation: The irrigation rate and duration are managed according to the clinical order, patient response and facility protocol.
Important: Cystoclysis is a clinical procedure rather than a routine self-care technique. It should be initiated, adjusted and discontinued only by trained healthcare professionals following the prescription, product instructions and local protocol.

How Is Urine Output Calculated During Cystoclysis?
Fluid collected in the drainage bag during continuous bladder irrigation contains both the patient’s urine and the irrigation solution that has passed through the bladder. The total drainage volume therefore does not represent true urine output by itself.
True Urine Output = Total Drainage Output − Irrigation Fluid Infused
Example: If the drainage bag contains 2,400 mL and 2,000 mL of irrigation solution has been infused during the same measurement period, the calculated urine output is:
2,400 mL − 2,000 mL = 400 mL true urine output
Accurate calculation requires irrigation input and total drainage output to be measured over the same time period. Clinical documentation requirements may vary between healthcare facilities.
What Should Be Monitored During Cystoclysis?
Effective cystoclysis monitoring involves more than checking whether fluid is moving through the tubing. Healthcare professionals evaluate the complete irrigation and drainage system together with the patient’s clinical condition.
Irrigation input: The volume and rate of irrigation solution entering the bladder
Total drainage output: The combined volume of urine and irrigation return
True urine output: Total drainage minus irrigation fluid infused
Drainage colour: Changes in the appearance and concentration of blood in the returning fluid
Clots and debris: The presence, amount and progression of visible material
Catheter patency: Whether fluid is entering and returning through the intended pathways
Patient response: Pain, bladder fullness, spasms, discomfort or changes in condition
System integrity: Kinks, disconnections, leakage, catheter bypassing or an unexpectedly empty drainage bag
Reduced or absent drainage, increasing discomfort, leakage around the catheter or a mismatch between irrigation input and output requires prompt clinical assessment.
Safety Considerations and Possible Complications
Bladder irrigation should be performed only when clinically indicated. The irrigation solution, catheter, tubing set, connection method, flow rate and duration must be appropriate for the intended use.
Key safety considerations include:
Maintain the required infection-control technique: Use appropriate sterile equipment and minimise unnecessary disconnection of the irrigation and drainage pathways.
Confirm the correct catheter lumen: The irrigation set must be connected to the designated irrigation port rather than the balloon-inflation port.
Avoid forceful irrigation: Resistance, pain or poor return flow should be assessed rather than overcome by uncontrolled pressure.
Maintain unobstructed drainage: Tubing should be checked for kinks, dependent loops, closed clamps and other causes of restricted flow.
Monitor fluid balance: Irrigation input and drainage output should be recorded so that true urine output can be calculated.
Possible complications may include:
Catheter blockage caused by blood clots or debris
Urinary tract infection
Leakage or catheter bypassing
Bladder spasms, pressure or discomfort
Bladder overdistension when inflow exceeds drainage
Bladder or urinary-tract injury in rare circumstances
Frequently Asked Questions About Cystoclysis
Is cystoclysis the same as bladder irrigation?
Cystoclysis generally refers to the process of introducing irrigation fluid into the bladder. In practical clinical and search terminology, it is commonly associated with bladder irrigation and especially continuous bladder irrigation.
Is cystoclysis always continuous?
No. Bladder irrigation may be continuous, intermittent or manual. The selected method depends on the clinical indication and approved protocol.
What catheter is used for cystoclysis?
Continuous bladder irrigation commonly uses a three-way urinary catheter. Its separate lumens support irrigation inflow, drainage outflow and balloon inflation.
What solution is used for bladder irrigation?
The irrigation solution must be prescribed and compatible with the catheter, irrigation set and clinical application. Sterile saline is commonly used in continuous bladder irrigation, but the final selection must follow the clinical order and institutional protocol.
How is true urine output calculated during cystoclysis?
Subtract the volume of irrigation fluid infused from the total volume collected in the drainage bag during the same measurement period.
What indicates that a cystoclysis system may not be draining correctly?
Warning signs may include reduced or absent drainage, increasing bladder discomfort, leakage around the catheter, visible tubing obstruction or a significant difference between irrigation input and drainage output. These findings require clinical assessment.
Conclusion
Cystoclysis is a bladder irrigation process used to help maintain catheter patency, remove or prevent blood-clot accumulation and support urine drainage. Continuous cystoclysis usually combines a prescribed irrigation solution, a bladder irrigation set, a three-way catheter and a urine drainage system.
Safe and effective irrigation depends on correct equipment selection, secure system connections, controlled fluid delivery and careful monitoring of both irrigation input and drainage output. Clinical decisions should always follow the treating professional’s order, the applicable product instructions and the healthcare facility’s approved protocol.
