Intermittent catheterization, often called a “straight cath,” is a medical procedure involving the temporary insertion of a thin, flexible tube into the bladder to allow urine to drain. This technique is used for individuals unable to empty their bladder naturally (urinary retention) or for managing chronic issues like a neurogenic bladder. Completely emptying the bladder regularly prevents infection and protects kidney health. This information is for general understanding only and must not replace specific, hands-on training from a qualified doctor or nurse before attempting the procedure.
Preparing for Intermittent Catheterization
Preparation begins with meticulous hygiene, starting with a thorough washing of the hands with soap and water. This step prevents introducing bacteria into the urinary system during the procedure. Gather all necessary supplies and place them on a clean surface within easy reach.
Essential items include the prescribed catheter, water-soluble lubricating jelly, antiseptic wipes or cleaning solution, and a container if not draining directly into a toilet. Hydrophilic catheters are pre-lubricated and activate upon exposure to water. Position the individual comfortably, such as sitting on a toilet or lying on their back with legs relaxed and slightly spread for optimal access.
Step-by-Step Guide to Catheter Insertion
The first step involves cleaning the tip of the penis, or meatus. If uncircumcised, gently retract the foreskin before cleaning. Use an antiseptic wipe or a clean washcloth with soap and water to clean the meatus in a circular motion, moving outward to clear contaminants.
Prepare the catheter by applying a generous amount of water-soluble lubricant to the tip and the first few inches, unless a pre-lubricated type is used. Hold the penis straight out and slightly upward toward the abdomen; this straightens the natural curve of the male urethra. This positioning makes the catheter passage smoother and reduces irritation.
Slowly and gently insert the lubricated catheter into the urethral opening. Continue insertion with steady, non-forceful pressure until urine begins to flow, typically after advancing the catheter six to eight inches. Resistance may be felt as the catheter reaches the external urethral sphincter and prostate area. If resistance occurs, pause, take a deep breath, or apply gentle, steady pressure to help the muscle relax, allowing the catheter to pass without injury. Once urine starts flowing, advance the catheter one to two more inches to ensure the tip is fully in the bladder.
Completing Drainage and Catheter Removal
Once the catheter is fully inserted and urine flow begins, allow the penis to return to a natural, downward position to facilitate complete bladder emptying. The catheter must remain in place until the flow of urine stops completely. To confirm the bladder is fully drained, gently press on the lower abdomen over the bladder area or slightly reposition the body to help release any residual urine.
After the flow has ceased, slowly and steadily withdraw the catheter. Gently pinch the catheter as it is removed to prevent remaining urine inside the tube from dripping onto clothing or skin. Dispose of the used supplies and the catheter properly in a waste receptacle. If tracking fluid output is required, measure and record the volume of urine collected for the healthcare provider.
Monitoring for Acute Complications
Following catheterization, monitor for signs of potential complications requiring immediate medical attention. The most frequent complication is a urinary tract infection (UTI), which presents with symptoms like fever, chills, or urine that appears cloudy or has a foul odor. Pain or a burning sensation during urination or a frequent, urgent need to urinate also indicate a developing infection.
Signs of acute trauma or bleeding are a serious concern and may include visible blood in the urine or severe pain during or immediately after the procedure. If the catheter cannot be advanced after two or three gentle attempts, or if the individual experiences sharp pain during insertion, the procedure must be immediately stopped. Forcing the catheter can cause urethral injury, so seek medical help right away to prevent long-term damage.

Slight resistance may be encountered as the catheter reaches the external urethral sphincter and prostate area. If resistance is felt, pause, take a deep breath, or apply gentle, sustained pressure to help the muscle relax, allowing the catheter to pass safely. Once urine flow is established, advance the catheter one to two more inches to confirm the tip is fully inside the bladder.

After the catheter is fully inserted and urine flow begins, allow the penis to return to a natural, downward position to facilitate complete bladder emptying. The catheter must remain in place until the flow of urine stops completely. To ensure the bladder is fully drained, gently press on the lower abdomen over the bladder area or slightly shift the body’s position to help release any final residual urine.
Once the flow has ceased, slowly and steadily withdraw the catheter. Gently pinching the catheter as it is removed prevents remaining urine inside the tube from dripping onto clothing or skin.
