Prostate B-ultrasound

Prostate B ultrasound uses B-mode ultrasound to examine the prostate. Clinically used to determine the shape, size and location of the prostate, can be used to diagnose benign prostatic hyperplasia, prostate tumors, stones, calcification and prostate abscess, cysts and chronic prostatitis, can also be used to detect the position of the prostatic urethral alloy stent tube. It is also suitable for patients with suspected prostate disease and is often used for physical examination in healthy men. Basic Information Specialist classification: male examination inspection classification: ultrasound Applicable gender: whether the male is fasting: not fasting Tips: Preservation of bladder urine before examination, can drink 400-600 ml of warm water 2 hours before the examination, do not urinate 2-4 hours before the examination. Normal value The prostate is the gonad that surrounds the urethra of the prostate. The normal transverse diameter is about 4 cm, the longitudinal diameter is about 3 cm, and the thickness is about 2 cm. The cross section is a symmetrical and blunt triangle, which is large and small. The prostate capsule is smooth and thin, with a low echo in nature, and a uniform distribution of fine spots. Clinical significance 1. Ultrasound sonogram of benign prostatic hyperplasia shows enlargement of the prostate, which is mainly caused by the increase of the posterior diameter, which loses its normal shape and is hemispherical or nearly spherical. The shape of the gland is regular, symmetrical, and the edges are neat. The envelope can be thickened, but the connection is complete. The internal echo is increased and the distribution is basically uniform. Patients with enlarged mid-leaf may be accompanied by urinary retention and residual urine. 2. Ultrasound sonogram of prostate cancer shows prostate deformity, enlargement, asymmetrical shape, irregular contour, incompleteness, loss of continuity of capsule fracture, uneven internal echo, localized spot, spot or light group, also The presence of focal hypoechoic areas. When some cases involve the bladder or seminal vesicle, a corresponding abnormal ultrasound image may appear. 3. Chronic prostatitis gland size changes little, can be slightly larger or smaller. The sonogram is a symmetrical chestnut or half moon. The envelope echo is thickened by the progression of inflammation and is uneven in thickness, but generally maintains its integrity and continuity. The internal echo is increased, the spot size is not equal, and the distribution is uneven. 4. Prostate stones (1) scattered in the small stone prostate size is normal, there are a number of scattered strong echoes, diameter 1-3cm, no sound shadow. (2) Curved stones are associated with benign prostatic hyperplasia. Stones appear at the junction of the inner gland and the outer gland. Many small stones are arranged in an arc shape, mostly without sound shadow. Only the stones are large, and the sound is formed when the aggregation is very dense or contains many calcium components. Longitudinal scanning through the rectum is easier to display curved stones. (3) Piles of small stones are also generally associated with benign prostatic hyperplasia. More than a dozen strong echo small stones are gathered into the heap, often seen near the tip of the prostate on the longitudinal section. (4) A single plaque-like strong echo of a single large stone occurs in the middle or left and right lateral lobe, about 5 mm or more, accompanied by sound and shadow, and the prostate does not enlarge or even shrink. This type is mostly shown in the transabdominal or transrectal cross section. 5. Prostate abscess is swollen and the capsule is intact. Symmetrical or asymmetrical, depending on where the abscess is located. The internal echo is changeable, and the liquefier is a low echo zone. If it is not liquefied or partially liquefied, the echo is uneven. If the abscess is worn around, the capsule is incomplete and the prostate is no longer swollen. After rectal detection, the abscess has been liquefied to see the flow echo in the abscess, which is helpful for diagnosis. A prostate abscess caused by aerobacteria or Escherichia coli, there is gas in the abscess, and the body position detection must be changed to avoid the influence of gas on the ultrasonic wave. 6. The prostate cyst has a circular or elliptical fluid area in the prostate, and the posterior echo is enhanced. The cyst is either confined within the prostate or protrudes into the bladder cavity. Cysts are generally small, at 1-2 cm or less. Large cysts may have signs of excitation of the lower urinary tract obstruction. 7. Prostate urethral alloy stent detection The acoustic image of the alloy stent is a duct-shaped reticulated strong echo, located in the progressive prostate urethra. The urethra was opened by the urethra, and there was no obstruction in the pipeline. The ultrasound detection path was better by the rectal method, and the longitudinal and transverse views were clear. High results may be diseases: non- leaching prostatitis, acute bacterial prostatitis, specific prostatitis, middle-aged and elderly men with partial androgen deficiency syndrome, male diseases, prostatitis, hemorrhagic disease, prostatic hyperplasia Before the examination: the bladder urine should be kept. You can drink 400-600 ml of warm water 2 hours before the examination. Do not urinate 2-4 hours before the examination (check after bloating). Inspection process Inspection method: B-ultrasound. Not suitable for the crowd Inappropriate people: Generally there are no people who are not suitable. Adverse reactions and risks Generally, this examination does not have too many adverse reactions and does not have much influence on the body.
