What does the prostate gland mainly examine?

The prostate is the largest gland in the male body. The prostate belongs to the accessory gland. The prostatic fluid secreted by the prostate is actually one of the main components of male semen. Therefore, the prostate is very important. You must pay attention to the care of the prostate in your life. When the prostate suffers from some diseases, you must go to the hospital for examination in time and receive treatment under the guidance of a doctor according to the specific symptoms.

Prostate examination usually involves rectal examination. By palpating the prostate through the rectum, the size, texture, presence of nodules, and pain of the prostate can be understood. The function of the urethral sphincter can also be indirectly understood by feeling the tension of the anal sphincter. If nodules are felt on the surface of the prostate, the possibility of prostate cancer should be considered. Blood PSA should be checked (increased in cases of prostate cancer), and a prostate puncture biopsy should be performed to confirm the diagnosis if necessary.

X-ray examination

It is of great value in the diagnosis of prostate diseases. For example, plain films can detect whether there is calcification or stone shadow in the prostate. Contrast imaging can help check whether there is prostate hyperplasia or prostate cancer. CT examination is even more important for the differential diagnosis of prostate diseases.

Tissue inspection

It is very useful for clarifying the nature of prostate masses and is extremely helpful for clarifying the histological typing and cytological characteristics of prostate tumors. It can be performed by transrectal needle aspiration biopsy or perineal puncture biopsy. It is painful and traumatic, but it is necessary.

In addition, lower urinary tract urine motility examination is very helpful in diagnosing prostatic hyperplasia. Cystoscopy can directly observe the hyperplasia of the posterior urethra, spermatophore, and middle and lateral lobes of the prostate, which is also very important for diagnosing prostate diseases.

Bladder and urethra examination is a method of inserting a catheter into the bladder and injecting 100-200ml of 3%-6% sodium iodide solution to make the bladder visible. It is mainly used to diagnose bladder tumors, bladder diverticula, external pressure, such as prostate hypertrophy and other diseases.

Gas has a good effect on showing bladder tumors, prostate hypertrophy, etc. Iodine and gas can also be used at the same time to form a double contrast. Inserting a catheter into the anterior urethra, or directly placing a syringe against the urethral opening, and injecting 12.5% ​​sodium iodide or 15% to 25% diatrizoate can show the lesions of the male urethra. After the excretory urography is completed, urination urethrography can also be performed, which is excretory urethrography. It is even more necessary for patients with urethral stenosis who cannot pass the catheter.

Ultrasound images are acoustic images of human organs and tissue structures. Such images are closely related to anatomical structures and pathological changes, and have certain regularity. However, current ultrasound images cannot reflect the characteristics of histology and cytopathology. Therefore, in the diagnosis work, ultrasound images must be combined with anatomical, pathological and clinical knowledge for analysis and judgment to make correct conclusions.
