Ureteral stents are usually removed in one to three months, and it is recommended to consult with the doctor who performed the surgery to avoid removing them too early or too late. Some patients with ureteral stenosis need to have a ureteral stent placed for a long period of time, up to six months to one year for replacement. Ureteral stents are commonly used to treat ureteral lithotripsy and ureteral strictures. Ureteral stents are retained during lithotripsy for support and drainage. They are usually removed on medical advice 2 weeks postoperatively after lithotripsy when the patient has recovered well. For ureteral stenosis patients, ureteral stents are retained according to individual circumstances and needs, depending on the doctor’s orders, and the same stent can be used for up to six months or one year. After removing the stent, it is recommended to rest more, drink more water, urinate frequently, do not hold urine, do not exercise strenuously, pay attention to light diet, try not to eat fried and stimulating food. Ureteral stents left in place for too long may lead to urinary tract infections and urinary stones. For patients with ureteral stents in their bodies, if they experience discomfort, they need to seek medical attention. Specific stent retention time needs to follow the doctor’s instructions.
