The symptoms of dripping after urination are that there is still residual dripping after urination. The cause of post-urinary dripping is complex, so patients should go to a regular hospital to examine the cause and treat it in a timely manner, remember not to take medicine blindly. Examination findings (1) Patients are all senior men, usually over 50 years old. (2) On examination, an enlarged bladder can be found in the lower abdomen. (3) During the anal finger examination, the prostate can be palpated and the central sulcus disappears or widens on both sides. The enlarged bladder can often be palpated at the upper edge of the enlarged gland. (4) Signs of hernia, hemorrhoids, prolapse and other comorbidities can also be detected. The diagnosis Prostatic hypertrophy is also known as benign prostatic hyperplasia, which is medically classified as histological prostatic hyperplasia and clinical prostatic hyperplasia. The former is detected by autopsy, which reveals a significant increase in prostate volume, or microscopic microscopic prostatic hyperplasia, but can be clinically symptomatic or asymptomatic. The latter can be determined by the following three items: (1) Prostate symptoms (frequent urination, nocturia, incomplete urine dripping, straining to urinate, etc.). (2) Enlarged prostate volume (prostate volume >20ml). (3) Indication of bladder outlet obstruction. For histological prostatic hyperplasia, the incidence is more or less the same in all countries from a worldwide perspective, and all have a clear relationship with age, i.e. increasing age increases the incidence. Foreign autopsy reports that prostatic hyperplasia is 10% at the age of 35, and later increases with age year by year to 85% at the age of 85. Diagnostic tests for prostatic hypertrophy: 1. Physical examination: check whether the patient is unresponsive, anemic, and swollen. Hypertension (to identify or exclude clues to early uremia); the presence and location of abdominal masses (to determine the compensatory or decompensated stage of urinary tract obstruction); the presence or absence of urethral discharge, whether the epididymis is enlarged (to determine the presence of co-infection). 2.Anal finger examination: check the anal sphincter tone (to distinguish neurogenic bladder) and prostate condition, pay attention to the size of prostate, whether the central groove disappears, whether there are nodules, prostate hardness, and whether there is pressure pain, etc. 3, laboratory tests: urine routine attention to find out whether there is a combination of urinary tract infection; blood routine and biochemical tests: hemoglobin decreased, urea nitrogen increased suggests uremia.
