Surgery is an important event for anyone. The success of the operation does not only require the doctor’s excellent medical skills, but also depends to a large extent on the patient’s close cooperation. This is especially true for patients with urethral strictures. If we compare the human body to a car, then the disease we suffer from is equivalent to a malfunction somewhere in the car, and the surgery is the process of removing the malfunction, while the correct post-operative attention and regular review is equivalent to the usual maintenance and regular maintenance of the car. So, what are the precautions after urethral stricture surgery? The main points are as follows: First, observe the change of urine flow: after urethral stricture surgery, patients and doctors are most worried about the recurrence of the stricture, so it is very important to observe the change of urine flow in general. Do not wait until the thin urine line is very serious and then come to the hospital, when a simple treatment may not help and another surgery is often needed. Regular follow-up: Just as cars need regular maintenance, people need regular maintenance, and even more so when they are sick. Urethral stricture is a difficult “lifelong disease” and can be considered a worldwide problem, so it is especially important for patients to have regular post-operative follow-up. Regular checkups allow the doctor to know whether your urination is smooth, whether there is urinary incontinence, whether there is sexual dysfunction, whether there are urinary stones, whether there is infection, etc., in order to deal with them in time and avoid delays and treatment. Third, drink more water: drinking more water can prevent inflammation and stones and reduce the chance of urinary tract obstruction. Pay attention to any abnormalities in the perineum, lower abdomen and scrotum: urethral stricture may produce some complications, such as urinary frequency, urinary urgency, pain and fever, leakage, redness, swelling and even pus in the wound or surrounding tissues, swollen and painful testicles, masses in the groin or scrotum, hemorrhoids and prolapse, etc. It may be the occurrence of urinary tract infection, urinary fistula, epididymitis, inguinal hernia and hemorrhoids, etc. If the above situation occurs, timely Seek medical attention.
