There are many patients with hypospadias in the Department of Urology at Union Hospital, and many patients come to our hospital for surgical treatment, as well as many patients who have undergone surgery at other hospitals but have poor results. The procedure of hypospadias surgery is very complicated and difficult. Postoperative care is also very demanding, and sometimes improper postoperative care can lead to bad consequences. In order to make the patients’ families better cooperate with the treatment, we would like to describe the post-operative precautions as follows, hoping that it will be helpful to all patients and their families. 1. Keep the drainage tube open to prevent dislodgement. After urethroplasty, a urethral stent tube or cystostomy tube will be placed to drain urine and support the urethra and prevent urethral stricture. Be careful to observe that the drainage tube is not folded or pressed, resulting in poor drainage; young children are easily moved and may need to turn over or move, so watch the drainage tube to prevent it from dislodging. 2, postoperative penile erection treatment After surgery, the penis may be prone to erection, and continued erection can lead to bleeding or even a formed urethral fracture. Erection of the penis is manifested by the child complaining of pain in the penis. Our doctor will explain to you that when the child is in pain, take an ice pack and put it on the inner thigh at the nurse’s station, usually for 1-2 minutes, and then put the ice pack back to the refrigerator at the nurse’s station. 3.Post-operative dressing change and stitch removal Generally after 2-3 days after surgery, our doctor will change the patient’s medication, open the outside dressing gauze, and the inside dressing (Uto) will be opened about 1 week after surgery. From the date of opening the outside gauze, rinse twice a day with vital iodine, and dip the root of the penis in vital iodine after rinsing. Keep the wound dressing dry. When the child is young and has poor self-control, it should be guarded by someone to prevent scratching off the wound dressing. If the dressing comes off, it can cause contamination; in addition, the wound dressing may sometimes be soaked with urine, and the health care provider should be informed promptly to change the dressing. All wounds use absorbable sutures, which will be absorbed or fall off automatically after 1 month. 4, postoperative diet 6 hours after surgery can feed the child a small amount of water, if no abdominal distension and other conditions appear, older children can eat thin rice noodles and other easily digestible food, preoperative breastfeeding children can also be fed milk 6 hours after surgery. Pay attention to strengthen nutrition, steamed eggs, steamed meat, fish, etc. are excellent foods, and it is recommended to supplement with vegetables and fruits. 5.Drainage tube removal The urinary catheter may be removed after 10-28 days after surgery depending on the condition, sometimes with a tube for urination, the doctor decides according to the condition. After the urinary catheter is completely removed, please observe the patient’s urination. If there is effort to urinate, thin urine line, or stool is discharged when urinating, please come to the hospital in time. 6.Routine follow-up time: 1 month after surgery is the routine follow-up time.
