Definition and causes

An enlarged prostate (prostatic hyperplasia) is caused by a benign growth of kirtelvævet in men. There is both growth of the central kirtelvæv, surrounding the urethra, and growth of smooth muscle and tissue in Volume glands. Prostate can both grow around the urethra, so that this will be squeezed in, and it can grow up in the urinary bladder.

The centerpiece of the disease is that the increased growth of glands pushing urethra, which ended the resistance of urine from the bladder becomes bigger, and it is therefore more difficult to empty the urinary bladder.

This may in the long term due to overfilling of the bladder cause complications weakening of the bladder muscle and tend to residualurin (residual urine) in bladder after urination.

Prostatahypertrofi are extremely frequent among older, and there was an increase with age so that 80% of men over 80 years, changes in the prostate. Approximately 10-25% of these sheep so pronounced prostataforstørrelse that they are consuming operation within 80 years of age.

It will be referred to a specialist unit (urological department) of getting into a flow survey (measuring pressure and volume of urine), which is how pronounced the obstruction of the urethra is, and how effective the bladder muscle is. Here you can also make an ultrasound of the bladder after urination to get an idea of how much urine is left. By suspicion of prostate cancer or by a very large prostate can you create an ultrasound of the prostate through endeta

In severe cases, where there is blood in the urine, or blood tests indicate kidney damage, can undergo a contrast study of kidney and urinary tract to see if there are changes in the kidneys and urinary leaders.

In rare cases where the prostate is very large, an open surgery. There is always risk of infection and bleeding in the surgical treatment, but the risk is very small.

You can also use a procedure called transuretral mikrobølgetermoterapi, which through urethra heat treating prostate cancer, so that size is reduced. The effect is about. 20-30%.

In the event that none of the above options are possible, takes Monday a permanent catheter (a plastic-long) through the urethra to the bladder, so that you can get by with urine.
