Description: URETHRAL CATHETERISATION After a thorough hand wash, sterile gloves are donned. The genitalia are cleaned using soapy antiseptic. Lidocaine gel is inseed into the urethra, warning the patient that this may create stinging. The jelly should be massaged posteriorly in an attempt to anaesthetise the sphincter region, and it is of advantage to place a penile clamp for several minutes. A small Foley catheter should be passed while the penis is heldtaut. In a female patient, the labia should be paed using the middle and index fingers of the left hand, which should not be moved once cleaning has been performed. Provided that a stricture is not the cause, the catheter should pass freely. Once urine begins to drain it is wise to pass a few more centimetres of catheter into the bladder before the balloon is inflated to avoid inflation in the prostate. Force must not be used. If the catheter will not pass, it is usually due to poor tech nique, lack of anaesthesia, traumatisation of the urethra or a urethral stricture. Occasionally, a large prostatic middle lobe may prevent the catheter entering the bladder; sometimes a coude catheter will pass. If a catheter cannot be passed the following plan should be pursued.
