DJ tube needs to take KUB (abdominal X-ray plain film) before extraction to clarify the location of the tube and the absence of stones. Pain may occur during the extraction process, and if the patient cannot tolerate it the DJ tube should be removed under anesthesia. After the tube is removed, there may be uncomfortable symptoms such as frequent urination, urgent urination, painful urination, hematuria, etc. For treatment, we should drink more water and urinate more often, and we can take oral anti-infective drugs if there are symptoms of frequent and urgent urination. If blood in urine appears, you can take oral hemostatic drugs. If the effect of oral antibiotics is not good, you can take oral medications such as Harlequin and Betanli to improve the symptoms of urinary tract irritation.
