bladder for continuous drainage of urine into a closed system.
The male urethral orifice (urinary meatus) is a vertical, slit-like opening, 0.15â€“0.2 in (4â€“5 mm) long, located at the tip of the penis. The foreskin of the penis may conceal the opening. This must be retracted to view the opening to be able to insert a catheter. With proper positioning, good lighting, and gloved hands, these anatomical landmarks can be identified. Perineal care or cleansing may be required to ensure a clean procedural environment.
The male urethra is longer than the female urethra and has two curves in it as it passes through the penis to the bladder. Catheterization of the male patient is traditionally performed without the use of local anesthetic gel to facilitate catheter insertion. Glands along the urethra provide some natural lubrication. Older men may require lubrication. In such an instance, an anesthetic or antibacterial lubricant should be used.
Once the catheter is inserted, it is secured as appropriate for the catheter type. A straight catheter is typically secured with adhesive tape. An indwelling catheter is secured by inflating a bulb-like device inside of the bladder.
And in urology, it could be drugs or devices for bladder and prostate problems.
