Pyelonephritis
Does pyelonephritis cause a fever?
Pyelonephritis is actually a part of urinary tract infections, which are divided into cystitis and acute pyelonephritis. The main symptoms of cystitis are frequent urination, urgency, and painful urination, among other urinary irritative symptoms, and these do not involve fever. However, if cystitis is not treated in time, it can worsen into acute pyelonephritis, which then presents with symptoms such as fever and back pain. The fever with acute pyelonephritis can be quite high, often exceeding 38 or 39 degrees Celsius, and might last for two to three days. At this point, treatment requires anti-infective medications, which should be continued for two weeks without any interruption. If the treatment duration is insufficient, pyelonephritis may recur. It is important to drink plenty of water, urinate frequently, and avoid holding in urine. Drinking lots of water can help flush out bacteria from the urine early on, promoting a quicker recovery from the illness.
Can pyelonephritis lead to pregnancy?
Pyelonephritis is actually a urinary tract infection. It is not the same as nephritis, so do not confuse the two. Thus, pregnancy is completely feasible for someone with pyelonephritis; as long as the infection is treated, the urine test shows negative results, and there are no white blood cells, pregnancy can occur without any impact. Currently, the treatment for pyelonephritis is anti-infection therapy. Since the bacteria have entered the kidney via the urethra, this treatment needs to last for two weeks. If the treatment duration is insufficient, there could be a recurrence of pyelonephritis. Additionally, it is important to drink plenty of water, urinate frequently, avoid holding urine, consume more than 2500 milliliters of water daily, and maintain a light diet avoiding spicy and irritating foods.
How to check for pyelonephritis?
Pyelonephritis, also known as upper urinary tract infection, is mostly caused by bacterial infection and the inflammatory response of the urinary system. The screening for this disease involves routine urine tests. Presence of white blood cells in the urine, coupled with symptoms like fever and back pain, can lead to a preliminary diagnosis. However, to confirm the diagnosis and identify the specific infecting pathogen, a culture of midstream urine is needed. Generally, to exclude certain causes of pyelonephritis, it is also necessary for the patient to have blood sugar levels checked and an ultrasound of the urinary system conducted. These tests can confirm whether the patient has diabetes, urinary system stones, or obstructions in the urinary system. Male patients can also undergo a prostate ultrasound to rule out urinary obstruction caused by prostate enlargement. These examinations can also help determine why the patient might have developed pyelonephritis.
What causes acute pyelonephritis?
Acute pyelonephritis refers to an acute inflammatory disease caused by bacteria invading the renal pelvis. It is commonly seen in women of childbearing age, the elderly, individuals with weakened immune systems, and patients with urinary tract obstructions. The main clinical manifestations of acute pyelonephritis typically include frequent urination, increased urination frequency, painful urination, back pain, fever, cold stomach, and it can even present symptoms such as headache, whole body muscle soreness, nausea, and vomiting. The most common pathogen causing acute pyelonephritis is Escherichia coli, while other bacteria such as Klebsiella pneumoniae, Proteus, and Pseudomonas aeruginosa can also cause infections of acute pyelonephritis. Therefore, it is crucial to actively choose sensitive antibiotics for the treatment of acute pyelonephritis.
How is pyelonephritis diagnosed?
Pyelonephritis is an upper urinary tract infection, with over 95% caused by bacterial infections in areas such as the renal pelvis and calyces, leading to inflammation. As a type of bacterial infection, if a patient's urine routine shows leukocytes and there is percussion pain in the renal area, along with fever, these symptoms combined with the urine examination can essentially lead to a diagnosis. However, a definitive diagnosis requires a culture of clean-catch midstream urine. If the bacteria in two consecutive urine cultures exceed 100,000 per milliliter and are the same type, the patient can be clearly diagnosed with pyelonephritis.
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).
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.
