Hydronephrosis does not usually recover on its own, but requires medication or surgery to recover, depending on the cause of the hydronephrosis. Hydronephrosis may be a problem in the urinary system, such as obstruction in the urinary tract, or urinary stones, kidney stones, ureteral stenosis, urinary retention, all of which may cause hydronephrosis. Therefore, you can go to the urology department of a regular hospital for an examination, and only after the examination by professional instruments can you make a treatment plan. If the hydronephrosis is caused by kidney stones, physical therapy, such as extracorporeal lithotripsy, can be performed, and the hydronephrosis will gradually improve after the kidney stones are discharged from the body. If the hydronephrosis is caused by urinary tract stenosis, it can be treated by minimally invasive surgery, such as a urinary tract dilation surgery, which can remove the hydronephrosis. Patients should usually drink more water to increase the volume of urination. It is recommended that the diet should be light and try not to eat anything that is on fire, which can also cause difficulty in urination when on fire, thus leading to the occurrence of hydronephrosis.
