1、 Bladder calculus
When the urinary tract is unobstructed, stones generally do not grow in the bladder. Even if a stone falls from the ureter into the bladder, it can be excreted with urine. Elderly people with prostate hyperplasia are different.
2、 Damage to kidneys and even uremia
"Due to the pressure of the prostate gland on the urethra, the bladder needs to contract forcefully. If the pressure of the bladder cannot be relieved for a long time, the residual urine in the bladder gradually increases, and the bladder muscles become ischemic and hypoxic, becoming tensionless, and the bladder cavity expands.". "Later, urine in the bladder can pour back into the ureter and pelvis, causing hydronephrosis, and in severe cases, uremia.".
3、 Causes urinary retention and incontinence
Urinary retention can occur at any stage of the disease, most of which are caused by sudden congestion and edema of the prostate due to climate change, drinking, and fatigue. Excessive residual urine can cause the bladder to lose its contractile capacity and gradually increase the amount of urine remaining in the bladder. "When the bladder is excessively inflated, urine can unintentionally overflow from the urethral orifice. This phenomenon of urinary incontinence is called filling incontinence, and such patients must receive emergency treatment.".
4、 Inducing diseases such as hernia in the elderly
Some patients with benign prostatic hyperplasia may experience symptoms of difficulty urinating, requiring exertion and breathlessness to urinate. Due to frequent exertion, the intestines will protrude from weak areas of the abdomen, forming a hernia (small intestine gas). Sometimes patients may also develop hemorrhoids and varicose veins in their lower limbs.
