Pyelonephritis is not nephritis, but a type of bacterial infection. Therefore, as a bacterial infection, there are no specific dietary restrictions for patients. Such patients should ensure adequate intake of fluids, with a recommended daily urine output of over 2000ml. This can help flush the urinary system and wash away some bacteria, reducing bacterial proliferation. Since it involves inflammation, it is advisable to follow a lighter diet, avoiding spicy, stimulating, and greasy foods, and focusing on easily digestible and warm foods.

Is pyelonephritis serious?

Pyelonephritis, also known as an upper urinary tract infection, occurs in the majority of cases when bacteria enter the renal pelvis and calices, causing an inflammatory response. This condition is indeed characterized by severe symptoms and an aggressive onset. Patients may suddenly develop a fever, with temperatures even exceeding 39°C, and experience back pain. Some patients may also exhibit clinical signs such as hematuria. The symptoms are indeed severe, and there is a pronounced systemic inflammatory response, leaving patients feeling listless, dizzy, headachy, and lacking appetite. However, the treatment for this disease generally yields good results. After antibiotic treatment, most patients can gradually see symptom relief within 3 to 5 days, and the condition is mostly curable after 10 to 14 days of medication.

The difference between pyelonephritis and nephritis

Pyelonephritis and nephritis are two completely different diseases. Pyelonephritis is an infectious disease caused by bacteria, viruses, mycoplasma, chlamydia, etc. Treatment generally requires the use of antibiotics. The vast majority of patients can fully recover within two weeks under the treatment of sensitive antibiotics, without any sequelae. On the other hand, nephritis is mostly an autoimmune disease, not an infectious disease caused by pathogens. Therefore, its treatment does not require the use of antibiotics. Treatment usually involves ACE inhibitors or ARB type RUSH blockers, glucocorticoids, immunosuppressants, cytotoxic drugs, etc., and the course of nephritis is relatively long, with some patients having relatively poor prognosis. (Please use medication under the guidance of a doctor.)

Pyelonephritis is an infection of the kidneys

In fact, pyelonephritis is not really nephritis; it is actually a type of bacterial inflammatory infection. Bacteria can infect many parts of the body. If the urinary system is infected and it reaches the renal pelvis and calyces, it is referred to as pyelonephritis. Over 95% of pyelonephritis cases are caused by bacterial infections, and 70% are due to Escherichia coli. Generally, this bacteria enters the urinary system from the urethral opening and ascends to the renal pelvis and calyces, where it proliferates and causes an inflammatory response. The main clinical symptoms of the patient are fever and back pain, and the patient may also experience gross hematuria (visible blood in urine).

Is pyelonephritis more serious or nephritis more serious?

Pyelonephritis is an upper urinary tract infection caused by a bacterial infection, leading to an inflammatory response in the urinary system. The severity of this condition can vary. Nephritis, on the other hand, refers to the sterile inflammation within the glomeruli of the kidney, which also varies in severity. Therefore, it is challenging to compare these two diseases in terms of their severity. In the case of pyelonephritis, most conditions are relatively more treatable, and using antibiotics can control acute pyelonephritis. However, a small number of patients may develop severe complications such as perinephric abscess, acute renal failure, renal papillary necrosis, and even death from septic shock. The severity of nephritis also varies, with symptoms ranging from significant proteinuria to mild hematuria. Therefore, a comparison should be based on the specific conditions of the patients. (The use of medications should be under the guidance of a doctor.)

How to diagnose pyelonephritis?

For the diagnosis of pyelonephritis, it is first necessary to confirm the diagnosis. Generally, patients should first undergo routine urine tests. In these tests, the presence of white blood cells and positive nitrites, along with clinical symptoms such as back pain, blood in urine, and fever are common. A routine blood test often shows elevated white blood cells and C-reactive protein. These indicators together suggest the presence of pyelonephritis. Furthermore, a culture of a clean-catch midstream urine sample can be done. If the bacteria grow to a certain quantity, it can also help in confirming the diagnosis of pyelonephritis. Additionally, to assess complications associated with pyelonephritis, it is necessary to perform blood tests for kidney function and an ultrasound of the urinary system to rule out conditions such as acute renal failure, renal papillary necrosis, and perinephric abscess, among others.
