Only for medical professionals to read and refer to the ultrasound diagnosis of bladder tumors.
Normal urinary bladder (normal urinary bladder) transverse cross-sectional sonogram, in males is oval, female bladder behind the uterine pressure marks, longitudinal sonogram is slightly triangular.
The normal bladder wall is a strip of echo, surrounding the anechoic area of urine, with a thickness of about 1-3mm, which varies with the degree of bladder filling.
The echo of the bladder wall is divided into two layers, the inner layer is mucous membrane, the echo is slightly lower, when the bladder is full, the surface is smooth, when the bladder is underfilled, the surface is wrinkled and uneven; the outer layer is the muscular layer, showing high echo.
At the left and right upper corners of the bladder triangle, there is a mound-like bulge, which is the exit of the ureter.
When the urine is sprayed, there is an opening and closing action, and the color blood flow chart can show the sprayed urine, which is red.
In the lower corner of the bladder triangle, there is a small recess, which is the internal opening of the urethra, and the bladder neck is around it.
Bladder tumor (bladder tumor) has two types: epithelial and non-epithelial.
Epithelial tumors accounted for 98%, and non-epithelial tumors accounted for only 2%.
1 Ultrasonography of epithelial bladder tumors The vast majority of epithelial bladder tumors are transitional cell carcinoma, adenocarcinoma, and squamous cell carcinoma, which account for only a small portion , Benign transitional epithelial papillary carcinoma occasionally occurs.
A part of the tumor protrudes into the bladder cavity, which is papillary or cauliflower-like with moderate or even high echo.
On the other hand, the base of the tumor grows toward the bladder wall and is hypoechoic, which interrupts or disappears the echo of the bladder wall, even with the surrounding tissues of the bladder.
There is no boundary between them.
The color blood flow chart shows that there is color arterial blood flow into the tumor at the base of the tumor.
According to the depth of the tumor invading the bladder wall in the ultrasound image and the wideness of the tumor base, the nature of the tumor and the stage can be estimated.
The pedicled tumor is not deeply infiltrated, the stage is low, and most of it is T1 stage, and the degree of malignancy is not high; The basal is broad, the bladder wall echo is interrupted or disappeared, the stage is high, the stage T3 or above, the degree of malignancy is high.
A burr-like hyperechoic on the surface of the tumor is a manifestation of transitional epithelial papillary tumors.
Tumors do not bulge much toward the bladder cavity, and those with a broad base and deep infiltration have a high possibility of adenocarcinoma and squamous epithelial carcinoma.

One is benign, such as leiomyoma and pheochromocytoma; the other is malignant, such as rhabdomyosarcoma and grape cluster sarcoma.
The benign tumor is located in the bladder wall, does not protrude toward the bladder wall, or only bulges, the surface mucosa is echogenic, and the sarcoma also protrudes into the bladder cavity, but invades the bladder wall significantly.
Non-epithelial tumors have rich colored blood flow.

Bladder tumor and intestinal primary tumor echo cannot be separated, thus the diagnosis can be obtained.
The intestinal tumor in the sonogram can be confirmed by the gas echo detected in the mass.
