Hydrocele usually does not cause heel pain, but if the condition of pyelonephrosis is more serious or combined with infection, it may lead to uncomfortable symptoms such as soreness or pain in the lower back. Patients with hydronephrosis are advised to undergo relevant examinations to clarify the cause of hydronephrosis and then carry out symptomatic treatment. If the hydronephrosis is caused by the narrowing of the ureteral junction of the renal pelvis, pyeloplasty can be performed under the guidance of a doctor. If the hydronephrosis is caused by ureteral stone embedded in the ureter, laser lithotripsy and other treatments can be carried out under the guidance of the doctor. If the patient has heel pain, it is recommended to go to the orthopedic department in time, and if necessary, lumbar spine nuclear magnetic examination can be carried out to determine whether the pain is caused by lumbar disc herniation. Patients with hydronephrosis are advised to go to regular hospitals in time and receive standardized treatment under the guidance of doctors.
