Hydronephrosis caused by stones is generally important, and patients are advised to take timely therapeutic measures to relieve the obstruction so as to improve the prognosis of the disease. Hydronephrosis refers to a series of symptoms caused by the obstruction of urine drainage from the renal pelvis, which is caused by the increased intrarenal pressure and dilatation of the renal pelvis and calyces when it accumulates. Its etiology is related to urinary tract stones, which can occur in the renal pelvis, renal calyces, ureters, bladder, urethra, thus causing urinary tract obstruction. If the patient suffers from urinary tract obstruction for a long time, it will cause damage to kidney function and jeopardize the patient’s health. Therefore, once diagnosed with hydronephrosis, patients can take oral antibiotic drugs, such as ofloxacin and amoxicillin under the guidance of doctors. Or take oral stone dissolving drugs, such as potassium sodium citrate, sodium bicarbonate and so on. Or take extracorporeal shock wave lithotripsy, ureteroscopy lithotripsy lithotripsy, nephrectomy and so on. Patients with hydronephrosis need to take into account their own situation and actively cooperate with doctors to take relevant treatment measures. During the treatment period, you need to ensure sufficient rest time, do not overwork.
