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.

Symptoms of recurring pyelonephritis

Pyelonephritis is an upper urinary tract infection. When the condition recurs, the initial symptoms are similar. Patients may also experience fever, and the temperature can rise quickly, even up to 40 degrees Celsius. There may also be a systemic inflammatory response, characterized by fatigue and loss of appetite, among other symptoms. Recurrence can also cause pain in the lumbar region, which may even radiate to the perineal area, and patients may also experience visible hematuria. In urinalysis, leukocytes or positive leukocyte esterase can be observed. These are the symptoms of recurring pyelonephritis.

What causes acute pyelonephritis?

Acute pyelonephritis, also known as an upper urinary tract infection, occurs when certain pathogens enter the urinary system and cause inflammation in areas such as the renal pelvis and calyces. Patients typically exhibit symptoms such as fever, back pain, and may also experience visible blood in the urine. The condition often has a severe onset. The common pathogens causing this type of infection primarily include bacteria, fungi, and viruses, among which the vast majority of cases are caused by bacterial infections. Furthermore, Gram-negative bacilli constitute the majority of these bacteria, with Escherichia coli being the most common.

Is pyelonephritis easy to treat?

Pyelonephritis is generally not difficult to treat. Because the condition often appears quite aggressive, it is caused by bacteria entering the urinary system through the urethra, leading to an inflammatory response. Therefore, the primary treatment involves using antibiotics to kill the bacteria. Most of the bacteria causing pyelonephritis are Gram-negative rods, so antibiotics sensitive to Gram-negative rods are often chosen. After a treatment course of 10-14 days, the patient's condition is generally controllable and curable. However, there are also a few cases of chronic pyelonephritis, involving complex factors related to urinary tract infections, such as urinary tract malformations, urinary system stones, prostate hyperplasia, diabetes, etc., which make treatment more difficult. (Medication should be used under the guidance of a doctor.)

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.

Acute Pyelonephritis Nursing Measures

Acute pyelonephritis, also known as an upper urinary tract infection, is a type of bacterial inflammation. In terms of care, patients should first focus on increasing their fluid intake. If the patient does not have urinary system stones, tumors, or other factors causing urinary obstruction—that is, if there is no kidney hydronephrosis—it is recommended that the patient's daily urine output be maintained at 2000-2500 milliliters. This means increasing fluid intake can help flush the urinary system, reducing bacterial growth and reproduction, which is beneficial for the treatment of pyelonephritis. Secondly, since the patient has acute inflammation, dietary considerations should include eating light, avoiding heavy and greasy foods as well as spicy and stimulating foods, and paying attention to perineal hygiene. Additionally, during episodes of fever, if the patient's body temperature is not very high, a warm water sponge bath can be given, especially focusing on the neck, armpits, and the root of the thighs, which can facilitate heat dissipation and is very beneficial for reducing body temperature.
