Wang Xiang, Department of Urology, Fudan University Hospital of Pediatrics, wants to help: 1. whether the persistent low fever will cause significant damage to the body; 2. whether surgery is necessary for the 6mm stone. If surgery, which procedure is better to use. Hospital Department Visited: Department of Surgery, Shengsi County People’s Hospital Medication used: Drug name: Tanoxin hydrochloride extended-release tablets, Sanjiu Kidney Stone granules Dosing instructions: Tanoxin hydrochloride extended-release tablets one tablet a day, Kidney Stone three times a day, one 5g packet each time. Wang Xiang replied: Hello, from the symptoms and ultrasound examination results, the diagnosis of double kidney stones with right ureteral upper segment stone obstruction should be clear. The main cause of the child’s discomfort now is the stone in the upper part of the right ureter, which forms a local obstruction in the ureter, triggering symptoms such as renal colic, nausea and vomiting, and also causing right hydronephrosis (16cm of separation of the collecting system? It should be mm, below 5mm in normal people). In addition, persistent low-grade fever indicates that there may also be a urinary tract infection. Treatment is firstly to relieve the symptoms, for example with antispasmodic and analgesic drugs, and pediatric anti-inflammatory pain suppositories are generally recommended. Secondly, there is no specific lithotripsy medication for children. Tamsulosin is an adult medication, not recommended for children, and has certain adverse effects. Chinese herbal lithotripsy medicines are also not recommended for young children because some Chinese medicines can damage the kidneys of children. If you want to use Chinese medicine for stone removal, it is recommended to get a prescription from a Chinese medicine doctor in a children’s hospital. Then, stone removal in children mainly relies on drinking more water or intravenous rehydration and maintaining a certain amount of activity to help the stones to be expelled. Generally, stones of 5-6 mm have a better chance of being expelled on their own. Third, if, during the observation of stone removal, the child develops recurrent abdominal pain, vomiting, hematuria or severe urinary tract infection, surgical treatment can be considered. Minimally invasive surgery, such as ureteroscopy, is recommended. The specific surgical method depends on the location of the stone, the age of the child, and the level of local medical technology. Fourth, it is recommended to perform urine routine and urine bacterial culture tests to clarify the presence of urinary tract infection, and if so, early antibiotic treatment.
