How is a ureteral stent removed?
Intermountain Healthcare answeredUreteral stents usually stay in for a few weeks, depending on the procedure you had. With some operations, the stent will stay in place for 6 weeks afterward. Your surgeon will give you the details. To remove most stents, a soft, flexible scope (about the size of a urine catheter) is sent up the urethra to the bladder. A grasper on the scope catches the stent and pulls it out through the urethra. The urologist will put numbing jelly inside the urethra before inserting the scope. You may feel some burning as the scope moves past certain parts of the urethra, but the procedure lasts just a few minutes. Pulling the stent feels a bit like pulling out a bladder catheter. Sometimes a short string is attached to the stent and hangs out of the urethra. In these cases, the stent is removed by pulling the string.
What can cause urinary problems in men besides an enlarged prostate?
It was once thought that the urinary difficulties that men experience as they age were the result of an enlarging prostate constricting the urethra. If this were the case, symptoms would tend to get worse as the prostate got larger. But this is not the case. Rather, the smooth muscle in the prostate and the bladder also play key roles in causing urinary symptoms. When the smooth muscle gets chronically tense, it puts pressure on the urethra and bladder neck, increasing the resistance to urine flow. And, as resistance to urine flow increases, the bladder has to work harder to empty itself. To do this, the bladder contracts its muscular wall, called the detrusor muscle. This action causes the muscle to thicken and get stronger, further reducing the capacity of the bladder.
Sometimes the muscle contracts when the bladder is not full, giving the sensation of needing to urinate. Over time, as the bladder tries harder to empty itself, it becomes less efficient. The result: The need to urinate more frequently and the sensation of not having emptied the bladder of urine.
What causes urethritis?
Urethritis, or inflammation of the urethra, has a few causes. The most common cause is a sexually transmitted infection. The infections that most commonly cause urethritis are gonorrhea, chlamydia, and herpes virus. Other causes of inflammation include contraceptive jelly, cream, or foam; spermicide used in condoms; and chemical irritation from soaps or lotions.
