Rectal examination, rectal examination is an easy and highly practical examination method for anorectal specialists. On the one hand, it can measure the tension of the anal sphincter, and on the other hand, it can touch the space-occupying lesion in the rectal cavity.

The rectal examination does not require any auxiliary equipment. At the time of the examination, the doctor puts on the disinfecting gloves in the right hand, and the outside of the index finger and the patient's anus are coated with some lubricating oil or petroleum jelly. Liquid paraffin oil is now commonly used.

Differential diagnosis

The symptoms of prostate induration need to be identified as follows.

Prostate tuberculosis: There is a prostate induration, similar to prostate cancer. However, the patient is younger and has other organs of the reproductive system, such as seminal vesicles, vas deferens, tuberculosis of the epididymis, or symptoms of urinary tuberculosis, such as frequent urination, urgency, dysuria, urethral secretions, and blood. Prostatic tuberculous nodules are locally infiltrated and have a loose texture. There are red and white blood cells in urine, prostatic fluid and semen. X-ray films sometimes show prostate calcification shadows, and typical tuberculosis lesions can be seen in prostate biopsy histopathology.

Prostatic stones: Prostate stones for rectal examination, the prostate is tough, sputum and stone hard and bursty. Pelvic X-ray showed visible stone shadows in the prostate area; B-ultrasound showed strong light group with sound and shadow in the prostate area.

Non-specific granulomatous prostatitis: The induration of this disease develops rapidly, with mountain-like protrusions, soft and hard, but elastic. Antibiotics and anti-inflammatory drugs are treated for 1-2 months, and the induration becomes smaller. Prostate hard biopsy biopsy tissue, rich in non-caseal granuloma under the microscope, filled with epithelial-like cells, mainly foam cells, surrounded by lymphocytes, plasma cells, eosinophils, glandular ducts often dilated and ruptured, full Inflammatory cells.

Nodular hyperplasia of the prostate: the prostate is diffusely enlarged, the surface is smooth, and there may be nodular sensation; PSA is generally in the normal range; B-ultrasound is enlarged, the light spot is uniform, the prostate capsule is continuously reflected, and the surrounding tissue The boundaries are clear.

Prostate cancer: It usually occurs in the posterior lobe. It grows slowly and is invisible. Therefore, the early symptoms are not obvious. Once symptoms appear, it is often more advanced. Late stage of prostate cancer is mainly characterized by lower urinary tract obstruction, or with hematuria and urinary retention. The most prominent symptom is pain.

Prostatic sarcoma: The incidence rate is higher in young people, including 1/3 of children; the disease develops rapidly and the course of disease is shorter. Rectal examination of prostate enlargement, but the texture is flexible, soft as cystic, and more with clinical symptoms of distant metastasis such as lung, liver and bone.
