Ureteral surgery is mostly performed through ureteroscopy, due to the thin wall of the ureter, the lumen is narrower, the surgical process will inevitably produce irritation or mucosal damage. Postoperative ureteral temporary spasm, mucosal congestion and edema and other factors will cause a short period of hidden pain performance, mostly normal phenomenon. Patients only need to pay attention to rest and observe more. You can also use some analgesic and antispasmodic drugs under the guidance of the doctor to relieve the symptoms, such as resorcinol and so on. In addition, after ureteral surgery will generally retain double J tube, surgery for ureteral stimulation and double J tube retained on the ureter stimulation will cause the affected side of the lumbar soreness, cramps or even colic, usually in the withdrawal of the double J tube symptoms will be relieved within a few days. If there is still significant discomfort after the tube is removed, further examination is needed to clarify the cause. If the patient has persistent obvious pain, obvious hematuria, abdominal pain and other manifestations after ureteral surgery, it should cause alarm, suggesting that there may be more serious postoperative complications, and should actively consult the doctor, and should be dealt with accordingly as soon as possible.
