Urethral dilatation is a common surgical procedure in urology that uses different types of urethral probes to dilate the urethra in order to treat the patient’s urethral stricture lesion and is a form of conservative treatment. Urethral stricture is a common urological condition and can be classified as congenital, inflammatory and traumatic according to its etiology. Severe urethral strictures can lead to upper urinary tract fluid and renal impairment, and in some cases can be complicated by periurethritis, periurethral abscess, or even perineal penetration into the scrotum to form a long-lasting urethral fistula, and are often complicated by urinary tract and genital tract infections, which require clinical treatment. Prior to clinical operation, guidance needs to be given according to the actual condition of the patient. In case of chronic inflammation of the urinary tract, it is necessary to take antibiotics 1-2 days in advance and drink more water at the same time. The specific procedure of surgery: according to the actual condition of the urethral stricture of the patient, choose the appropriate type of probe, apply the probe using a locally used lubricating anesthetic, insert the probe into the urethra, slowly send it into the bulbous urethra, then the tip of the probe crosses the After several repetitions, a slightly thicker type of probe is selected and the above operation is repeated, thus dilating the urethra. There may be urethral discomfort for a short period of time after the operation or there may be slight bleeding. Drink more water and if there is more bleeding, take Yunnan Baiyao or opt for a review, however, most patients can recover on their own. For the operation of urethral dilatation, it must be performed by a professional physician, never by yourself. It is recommended to visit a nearby hospital in time to choose the appropriate treatment plan and treatment cycle according to the condition of urethral stricture.
