Decrease in bladder capacity

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.

Differential diagnosis

Cystitis has specific and non-specific bacterial infections. The former refers to bladder tuberculosis. Non-specific cystitis is caused by Escherichia coli, E. coli, Proteus, Pseudomonas aeruginosa, Streptococcus faecalis, and Staphylococcus aureus. Its clinical manifestations are acute and chronic. The former has a sudden onset, a burning sensation during urination, and pain in the urethra area. Sometimes there is urgency and severe urination. It is very important that the above symptoms occur both in the evening and in the daytime, which is common in women. The terminal hematuria is common. There are gross hematuria and blood clots. The patient feels weak, has low fever, can also have high fever, and pubic discomfort and low back pain.

Bladder tumors are the most common tumors in the urinary system. Most are transitional epithelial cell carcinoma. The bladder wall and the posterior wall are the most, followed by the triangle and the top, which can be multi-centered. Bladder tumors may be accompanied by renal pelvis, ureter, and urethra tumors. In foreign countries, the incidence of bladder tumors ranks second only to prostate cancer in male genitourinary tumors; it ranks first in China. The incidence rate of males is about 3-4 times that of females, and the age is more than 50-70 years old. Epithelial tumors account for 95% of the disease type, of which more than 90% are transitional epithelial cell carcinoma. Abdominal ultrasound was used to measure bladder volume reduction.
