Abstract: It is difficult to understand the cause of benign prostatic hyperplasia for people without medical treatment. To understand the cause, you must first understand the structure of the prostate. The prostate is divided into two layers: the inner layer is the mucosa and submucosal glands around the urethra; the outer layer is the prostate body. The latter constitutes the main body of the prostate, with fibrous membranes separating the two layers. According to the proportion of interstitial and adenoid tissues, multiple cases of prostate hyperplasia


It is difficult to understand the cause of benign prostatic hyperplasia for people without medical treatment. To understand the cause, you must first understand the structure of the prostate. The prostate is divided into two layers: the inner layer is the mucosa and submucosal glands around the urethra; the outer layer is the prostate body. The latter constitutes the main body of the prostate, with fibrous membranes separating the two layers. According to the proportion of interstitial and adenoid tissues, multiple cases of prostate hyperplasia are divided into two types. The outward pressure of large and soft fibromuscular glandular nodules and small and hard fibromuscular hyperplasia of glands forces the outer prostate. The body gradually becomes a thin layer of fibroadenoid pseudocapsule. The prostatic hyperplasia causes obstruction of the bladder neck, and the bladder strengthens contraction in order to overcome the resistance of the neck, causing compensatory hypertrophy of the detrusor to form a trabecular protrusion. The bladder cavity pressure increases, and the bladder mucosa can bulge outward from the weak part of the muscle bundle, forming a diverticulum bladder neck obstruction. Continued to aggravate, urine will remain in the bladder to varying degrees. With the increase of residual urine, the bladder wall gradually becomes thinner, and the physiological valve formed by the lower end of the ureter obliquely passing through the muscular layer of the bladder wall fails. The urine in the bladder will flow back to the ureter and the renal pelvis, causing water accumulation in the upper urinary tract on both sides, increasing the pressure in the renal pelvis, causing ischemic atrophy of the renal parenchyma, and eventually causing dysfunction of renal function.
The symptoms of benign prostatic hyperplasia are mainly two groups of symptoms, one is bladder irritation symptoms; the other is obstructive symptoms caused by prostatic hyperplasia obstructing the urinary tract.
1. Bladder irritation symptoms: frequent urination, urgency, increased nocturia, and urgent urinary incontinence. Frequent urination is an early signal of benign prostatic hyperplasia, and the increased frequency of nocturia is more clinically significant. In general, the number of nocturia is often parallel to the degree of prostate hyperplasia. The old people who could not stay up at night showed 1-2 times of urination at night, which often reflected the onset of early obstruction, and developed from 2 times per night to 4-5 times or more per night, which showed the development and aggravation of the disease.

2. Symptoms of urination obstruction: mainly due to prostatic hyperplasia obstructing the urinary tract.

(1) Weak urination, thinning of the urethra, and dripping urine: Because of the obstruction of the prostatic hyperplasia, the patient needs to use more force to overcome the resistance to urination, which makes it difficult to urinate. In the development of urine, there may also be symptoms of interrupted urination and endless dripping after urination.

(2) Hematuria: Blood in the urine is hematuria, also known as hematuria. Under normal circumstances, there is no red blood cells in the urine. After medically precipitating a patient's urine by centrifugation, use a microscope to check. If there are more than 5 red blood cells in each high-power field, it is called hematuria.

(3) Urinary retention: In patients with advanced prostate hyperplasia, acute urinary retention can occur when the obstruction is severe due to cold, drinking, excessive urine holding time, or infection.

(4) Frequent urination is an early signal of benign prostatic hyperplasia, especially the increase in nocturia frequency is more clinically significant. In general, the number of nocturia is often parallel to the degree of prostate hyperplasia. The old people who could not stay up at night showed 1-2 times of urination at night, which often reflected the onset of early obstruction, and developed from 2 times per night to 4-5 times or more per night, which showed the development and aggravation of the disease.

Prostatitis examination items mainly include: blood urea nitrogen and creatinine measurement; phenol red excretion test; indigo carmine excretion test; urine concentration and dilution test; ordinary or high-dose intravenous urography. For more detailed inspection items, please pay attention to the relevant sections and articles about prostatitis on this site.
