Ultrasound examination of prostate and seminal vesicles

Ultrasound examination of prostate, seminal vesicle, scrotum and penis is a routine examination of male diseases, suitable for the diagnosis of the following diseases: 1, benign prostatic hyperplasia ("prostatic hypertrophy"), prostate cancer, prostatitis, prostate abscess, prostate cyst, prostate stone. 2, seminal vesicle inflammation, seminal vesicle cyst, seminal vesicle tumor and congenital seminal vesicle gland absent. Basic Information Specialist classification: male examination inspection classification: ultrasound Applicable gender: whether the male is fasting: not fasting Tips: After the abdominal wall scan, you need to fill the bladder properly, so drink plenty of water. Normal value The normal prostate image of the prostate is about 4 x 3 x 2 cm in size. Its cross section is symmetrical in the shape of a millet, the longitudinal section is oval, and the upper and lower are small. The echo of the prostate capsule is a flat continuous line, and the gland is a small spot with uniform distribution. Bright spots from the urethra are visible in the center of the image. Ultrasound measurements of normal prostate may vary depending on the route of examination and the type of ultrasound system, the location of the examination, and the angle of detection. Measurement method for abdominal examination. 1. Measuring cuts and parts 1. Abdominal cross section (slanted coronal section of the prostate). Wide path measurement (left and right diameter) The maximum diameter from the left boundary to the right boundary. Thick path measurement (front and rear diameter) The maximum diameter from the leading edge boundary to the trailing edge boundary. 2. Abdominal longitudinal section (sagittal section of the prostate). Long path measurement (upper and lower diameter) The maximum diameter from the upper edge boundary to the lower edge boundary. 2. Normal measurement of prostate The average diameter is 3 cm, the width is 4 cm, and the thickness is 2 cm. 3. Prostate volume calculation (V) The half value of the three-path product. That is, V = l / 2 (L · D · W). Adult seminal vesicles are distorted glandular sacs or glands, about 6 cm long and about 2 cm wide. They are only connected to the vas deferens under the ampulla. Clinical significance 1, rectal ultrasound examination helps to detect early 0.5 to 1.5 cm prostate cancer (PCA), the sensitivity is more than the rectal examination (the latter can only find 45% of the cancer). Ultrasound-guided biopsy can help diagnose PCA and differentiate it from other lesions such as granulomatous lesions, tuberculosis, inflammation, and benign proliferative. 2. Ultrasound is more helpful than X-ray and CT in judging the location, size, shape and extent of glandular invasion of prostate cancer. Combined with ultrasound-guided biopsy, it is helpful for the classification and staging of prostate cancer, which is of great significance in determining clinical diagnosis and treatment. 3, interventional ultrasound application: 1 ultrasound guided prostate biopsy. 2 by perineal prostate puncture pus, prostate cyst puncture aspiration and treatment. 3 Place the prostate stent, coil, etc. under ultrasound monitoring. High results may be diseases: acute epididymitis, bacterial prostatitis, prostate disease, male genital malformation, epididymitis considerations Preparation before inspection: 1 The abdominal wall scan requires a moderate filling of the bladder. 2 The rectal scan requires preparation of the rectum and instruments such as probe cleaning, disinfection, water injection, and exhaust, and the patient does not need to fill the bladder. 3 If the perineal scan is generally no special preparation is required. 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 This test generally has no adverse reactions.
