Patients with urethral strictures are most likely to have restenosis within 6 months after surgery, while the likelihood of recurrence decreases significantly after 1 year. For this reason, follow-up of patients after urethral stricture urethral reconstruction surgery is particularly necessary. It is very important to observe changes in the urine flow during the day. Once the urine line becomes thin, it often indicates that the urethral stricture has reached a certain level and needs to be treated as soon as possible. Do not wait until the thin urine line is very serious before coming to the hospital, as simple treatment may not help and another surgery is often needed. For this reason, we recommend regular review for patients with urethral stricture. Regular review allows 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 a timely manner and avoid delaying the disease and treatment. I. The catheter was removed 4 weeks after the operation, and urethrography was done at the same time, and the cystostomy tube was replaced. After the catheter is removed (the cystostomy tube is still in place), some patients will experience some discomfort when urinating on their own, usually caused by the fistula, and the specific common discomfort is as follows: 1. urinary frequency, urinary urgency When urinating on your own after the catheter is removed, you urinate more often and want to urinate afterwards; sometimes there is also urine holding, urinary urgency and so on. This is a normal phenomenon, probably because the catheter and cystostomy tube are in an open state for a long time after the urethral reconstruction surgery, resulting in partial retraction of the bladder after the removal of the tube, but with the extension of the removal time, it will gradually ease. However, some symptoms will disappear only after the removal of the fistula, which may be mostly due to the irritation of the fistula, and sometimes M-blockers can be applied appropriately to relieve the symptoms. 2, pain after urination Clamp the fistula, urinate by yourself, and feel pain in the urethra or lower abdomen at the end of urination. This postoperative discomfort is normal. It is mostly due to the irritation of the urethral opening and bladder triangle by the head of the fistula. The symptoms will be relieved slowly and will disappear after the removal of the fistula. 3, blood in the urine or hematuria Mostly at the end of urination, there is a little blood or light red blood in the urine. It is also normal and will be relieved or disappear after the removal of the fistula. Second, 4 weeks after removal of the catheter, if urination is clear, urography or cystoscopy is feasible, if the urethra is clear, the cystostomy tube can be removed. (It requires about cystoscopy, which is performed in the operating room). Third, thereafter, it is recommended to review every 4 weeks as an outpatient, and gradually extend the interval between outpatient reviews, and finally every six months for a long time. IV. Routine review items: urinary flow rate + residual urine ultrasound, urinary routine, urethrography and urethroscopic cystoscopy, choose one or more according to the situation at that time. V. Choice of urethral dilatation: without special circumstances, it is generally not recommended to choose urethral dilatation. Special patients still need to consider urethral dilatation in order to protect the postoperative results. If the patient’s urinary line does not become thin during the dilation interval, and at the same time the surgeon feels no significant contraction of the stenotic segment when performing urethral dilation, the dilation interval can be extended.
