Pyelonephritis
What should not be eaten with pyelonephritis?
Pyelonephritis is actually a type of urinary tract infection, which can be divided into pyelonephritis and cystitis. If the bacteria are confined to the bladder without other symptoms, it is called cystitis. At this time, anti-infection treatment is needed, and recovery can usually be achieved within about three to seven days. However, if cystitis is not treated in time, causing the bacteria to enter the kidney along the urinary tract, the patient may develop systemic fever, sometimes high fever from 38°C to 39°C, and may also experience kidney percussion pain, back pain, etc. This condition is called acute pyelonephritis, and its anti-infection treatment course requires two weeks. If the treatment course is insufficient, it is very easy to relapse. Currently, for the diet of pyelonephritis, it is important to maintain a low-salt, low-fat, light diet, avoid spicy, stimulating, cold food, drink more water, and urinate frequently.
Is pyelonephritis easy to treat?
Most cases of pyelonephritis start acutely, with patients abruptly experiencing bacterial infections in their urinary system, causing inflammation in areas such as the renal pelvis and calyces. This manifests clinically with symptoms such as fever and back pain. This acute onset type is called acute pyelonephritis, and it is relatively easy to treat because it involves a bacterial infection that requires antibacterial treatment. Hence, it is generally manageable. However, if a patient's condition becomes prolonged and turns into chronic pyelonephritis, treatment may be more challenging. The bacteria causing chronic pyelonephritis are often drug-resistant, and this condition might be associated with predisposing factors for urinary infections, such as urinary system stones, anatomical abnormalities of the urinary tract, or obstructions that can conceal bacteria or contribute to their resistance, making treatment more difficult.
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.)
Can pyelonephritis be cured?
Whether pyelonephritis can be cured mainly depends on whether the patient has predisposing factors for urinary tract infections. These factors primarily include: Firstly, abnormalities in the anatomical structure of the urinary tract that may lead to obstruction of urine excretion, such as urological system stones, tumors, prolonged indwelling catheters, congenital abnormalities of the urinary system, and others. Additionally, there are some conditions that may lead to a decreased immune response, such as elderly individuals who are bedridden, those with diabetes, or patients using immunosuppressants. If the aforementioned factors are present, treatment of such cases of pyelonephritis might be challenging, with patients possibly experiencing recurrent episodes and potentially progressing to chronic pyelonephritis, eventually becoming difficult to cure completely. However, if none of these factors exist, the majority of cases with simple acute pyelonephritis can be cured and controlled by medication.
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.
The difference between pyelonephritis and nephritis
Pyelonephritis and nephritis are two completely different concepts. Pyelonephritis is actually a bacterial inflammation, usually caused by bacteria at the urethral opening ascending into the urinary system and causing inflammation in areas like the renal pelvis and calyces. Patients may experience symptoms such as fever, hematuria, and back pain. In severe cases, it can cause necrosis of the renal papillae, leading to acute renal failure. Some patients may also develop perinephric abscesses, which are caused by bacterial infections. Nephritis, on the other hand, refers to inflammation within the glomeruli. This type of inflammation does not involve bacteria and is related to disorders in the body’s immune function. The disordered immune response is aggressive, attacking the glomerular filtration barrier, leading to proteinuria and hematuria. Therefore, the mechanisms of disease and treatment methods for the two conditions are different.
Principles of treatment for pyelonephritis
Pyelonephritis, also known as an upper urinary tract infection, is a bacterial inflammation, with over 95% being caused by bacterial infections, among which 70% are caused by Escherichia coli. Therefore, as a bacterial infection-induced inflammation, antibiotic treatment is of course necessary. Clinically, third-generation cephalosporins or fluoroquinolone antibiotics are often chosen for bactericidal treatment. For acute pyelonephritis, it is generally recommended that medication be administered for 14 days, alongside measures such as increased water intake and frequent urination. In cases of chronic pyelonephritis, a low-dose, long-course antibacterial treatment, such as using nitrofurantoin, may also be employed, with continuous medication for two months. (Please consult a clinical doctor for specific medication use; do not self-medicate.)
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.
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.
