1) Urinary tract infection. As the saying goes: "flowing water does not rot", but patients with prostatic hyperplasia often have varying degrees of inexhaustible urine and residual urine. The residual urine in the bladder is like a pool of stagnant water. Once the bacteria multiply, it will cause uncontrollable infection. Urine obstruction is a prerequisite for infection, so urinary tract infections are prone to occur.
2) Acute urinary retention. It is the most common complication of benign prostatic hyperplasia. Urinary retention can occur at any stage of the disease. It is mostly caused by sudden congestion and edema of the prostate caused by climate change, drinking, and fatigue.
3) Bladder stones. Bladder stones are easily formed due to obstruction of urine flow and secondary infection.
4) Hematuria. When bladder stones get worse and cause inflammation of the bladder, hematuria may occur.
5) Kidney damage. When the degree of obstruction gradually worsens, hydronephrosis, renal insufficiency, and renal hypertension may occur.
6) Hemorrhoids, prolapse of the anus. Difficulty in urination and long-term increase in abdominal pressure can easily cause complications such as hemorrhoids and prolapse.
7) Urinary incontinence. Excessive residual urine can make the bladder lose its ability to contract, and the urine retained in the bladder gradually increases. When the bladder is over-inflated, urine will overflow from the urethra unconsciously. This phenomenon of urinary incontinence is called filling urinary incontinence. Such patients must receive emergency treatment.
