Nephrology treats a wide range of diseases, including nephritis, nephropathy, kidney failure and urinary tract infections. As a patient, when you have the following symptoms, it is recommended to go to the nephrology department in time. 1, hematuria: including the increase of urine red blood cells found in the physical examination and the hematuria visible to the naked eye. 2.Increased foam in urine: This symptom mostly indicates proteinuria, and you are advised to seek medical consultation promptly. 3, edema: especially in patients with bilateral eyelid edema and symmetrical edema of both lower limbs. 4.Elevated blood creatinine: Any case of elevated blood creatinine should be promptly seen to find the cause for appropriate treatment. 5.Urinary frequency, urinary urgency and painful urination: these symptoms often suggest the presence of urinary tract infection. On the other hand, many patients have the following misconceptions when choosing nephrology for consultation. 1.Lumbar pain: Generally speaking, kidney diseases rarely present obvious lumbar pain, and some patients only have mild lumbar discomfort symptoms. Patients with obvious back pain are recommended to choose orthopedics or urology for consultation first. 2.Kidney deficiency: “Kidney deficiency” is a traditional Chinese medicine concept, which is not consistent with modern medicine’s kidney disease. Most of the symptoms of so-called “kidney deficiency” are not related to kidney disease. These patients are recommended to go to the TCM department or other related departments for consultation. 3, hydronephrosis, stones, cysts, occupancy, etc.: we recommend you to go to the urology department for timely consultation. 4.Prostate disease: We recommend you to visit urology department.
