Introduction

Introduction Bladder volume refers to the amount of urine in the bladder when there is urinary urgency and urgency. Under normal circumstances, the amount of urine discharged at one time is the bladder capacity. Residual urine refers to the amount of residual urine that cannot be discharged from the bladder after urination. When there is residual urine, the amount of urine discharged is not equal to the bladder capacity. At this time, the bladder capacity = the amount of urine discharged at one time. The normal bladder has a capacity of about 400 ml. When the bladder is inflamed, the bladder capacity is below 200 ml. The capacity of tuberculous bladder can be as small as 10 ml.

Cause

Cause

The pathological process of abnormal extracellular matrix and excessive deposition due to inflammation leading to necrosis of organ parenchymal cells.

Examine

an examination

Related inspection

Ultrasound of the bladder, cystography, urography, cystoscopy, blood routine

Clinical manifestations include lower abdominal pain, nocturia, and frequent urination.

Diagnosis

Differential diagnosis

Bladder neck fibrosis (also known as bladder neck fibrosis), usually secondary to inflammatory lesions, the age of onset is mild, symptoms appear in 40 to 50 years old, clinical manifestations are similar to benign prostatic hyperplasia, but rectal examination or B-ultrasound shows prostate The volume is not large, even if it is slightly increased, it is not the main cause of obstruction. After fibrosis of the bladder neck, the posterior lip often has different degrees of elevation (also known as fibrotic medial malleolus), but it is also different from the middle lobe hyperplasia. Because of the mid-lobe hyperplasia, the glandular lobes protrude into the bladder neck and bladder cavity, covering Smooth muscles and mucous membranes on the glands are soft. After bladder neck fibrosis contraction, the contraction of the posterior urethra and bladder triangle is shortened, and the neck is contracted toward the urethra to form a rigid annular stenosis, which can also cause lower urinary tract obstruction, but the rectal examination is not large. Cystoscopy is the most reliable differential diagnosis method.
