Hold the penis with your non-dominant hand, lifting the shaft upward at an angle of 60 to 90 degrees relative to the body. This maneuver extends the pendulous urethra and straightens out the first natural anatomical kink. Squeeze the sides of the glans lightly to open the urethral slit.

Take the catheter in your dominant hand, ensuring the indicator stripe faces straight up toward the patient's chest. Introduce the tip into the meatus insertion site. Advance the tube slowly, 2 to 3 centimeters at a time. Never push from several inches back on the shaft, as the flexible plastic will bow and lose forward momentum. Keep your eyes locked on that alignment ridge. Do not let the tube spin between your fingers.

At roughly 12 to 15 centimeters in, you will feel resistance. You have reached the external urethral sphincter and the bulbar curve. This is where most people panic and push aggressively. Never force it. The sphincter is a voluntary muscle; tension clamps it shut. Instruct the patient to exhale slowly, cough lightly, or bear down as if attempting to urinate. This natural reflex drops the pelvic floor, relaxing the sphincter just enough for the coudé tip to slide forward.

Continue advancing the catheter until the bifurcation or funnel reaches the tip of the penis. Urine should begin draining freely into the collection receptacle. If urine does not flow, advance the tube another centimeter or apply gentle suprapubic pressure over the lower abdomen. Once urine empties completely, pull the catheter back slowly by 1 to 2 centimeters at a time to catch any remaining fluid pockets at the bladder base before total removal.
