What foods to eat for pyelonephritis
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.
How do you get pyelonephritis?
Pyelonephritis, also known as upper urinary tract infection, is an inflammatory response caused by pathogens; 95% of pyelonephritis is caused by bacterial infections. Most cases involve bacteria from the urethral opening ascending into the urinary system to reach the kidneys, where they proliferate and cause inflammatory symptoms. Normally, there are bacteria present at the human urethral opening. Under normal immune function or absence of factors like significant urinary obstruction, it is unlikely for an upward bacterial infection to occur. However, under certain conditions, this type of infection may happen, prompting an inflammatory response from the pathogens.
What should I do if pyelonephritis recurs?
Pyelonephritis, also known as upper urinary tract infection, is an inflammatory reaction caused by bacterial infection of the urinary system. Therefore, in cases of recurrence of this condition, it is still necessary to use antibiotics for bactericidal treatment, generally requiring a full two-week course, choosing drugs with low nephrotoxicity. Additionally, it is important to investigate whether there are any complicating factors for pyelonephritis, such as the presence of diabetes, urinary system stones, tumors, or urinary tract anomalies. Identifying and addressing these complicating factors can reduce the likelihood of recurrence of pyelonephritis.
How is pyelonephritis caused?
Pyelonephritis can also be referred to as an upper urinary tract infection. It occurs when bacteria proliferate in parts of the kidney such as the renal pelvis and calyces, leading to inflammation. In most cases, these bacteria enter the urinary system retrogradely from the urethral opening and cause inflammation in areas like the renal pelvis and calyces. Normally, bacteria are already present at the urethral opening, and when the body's immune system is functioning well and the urinary system is unobstructed, it is difficult for these bacteria to enter the urinary system and cause an inflammatory response. However, in patients with weakened immune systems, such as those suffering from a cold, diabetes, or those using steroid medications, bacteria may enter the urinary system and replicate in large numbers. Additionally, if there are obstructive factors in the urinary system, such as prostate enlargement in male patients, or if the patient has urinary system stones or tumors, bacteria are more likely to cause an inflammatory response.
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).
