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.
Kidney hydronephrosis atrophy symptoms
Severe hydronephrosis may cause kidney atrophy. The symptoms of the patient can be divided into two aspects: Firstly, hydronephrosis may cause some clinical symptoms, such as some patients may experience swelling in the lumbar and back area, and a decrease in urine output. Patients may suffer from spasms of the ureter due to obstruction of the urinary system, resulting in severe pain, and some patients may also have hematuria. On the other hand, the atrophy of kidney tissue caused by this hydronephrosis actually means the loss of kidney function. Patients may exhibit symptoms of renal failure, such as swelling of limbs, increased blood pressure, nausea, vomiting, loss of appetite, anemia, and other clinical symptoms.
What are the symptoms of chronic kidney failure?
Chronic kidney failure generally may have some clinical symptoms, but many patients do not have any discomfort. Some common clinical symptoms mainly include increased urine foam and decreased urine output. Due to the decline in renal function for urine excretion, it can lead to edema, particularly in areas such as both ankles and the face. In the state of renal failure, patients may also experience hyperkalemia and metabolic acidosis. Due to metabolic acidosis, patients might exhibit deep and labored breathing. In the advanced stages of kidney failure, patients may suffer from renal anemia, leading to fatigue and potentially experiencing bone pain and susceptibility to fractures due to renal osteodystrophy.
Can renal cancer be detected by ultrasound?
Ultrasound is a type of imaging examination that can observe the size, shape, structure, texture, and the presence of masses in the organs being examined. It can be used to determine if a patient potentially has kidney-related masses, such as differentiating between a kidney cyst and kidney cancer based on differences in shape and blood supply that malignant tumors typically exhibit compared to other conditions. However, using ultrasound to diagnose kidney cancer can be inaccurate, particularly in the early stages of the disease when ultrasound may not provide a clear view, and some complex cases of kidney cancer may still be indeterminate. Therefore, patients might consider undergoing an enhanced CT scan, which offers a higher diagnostic accuracy. Additionally, a kidney biopsy and pathological examination might be necessary for a definitive diagnosis.
Can IgA nephropathy stage 2 be cured?
IgA nephropathy is an immunopathological diagnostic term for chronic glomerulonephritis, indicating that the patient has chronic nephritis. In fact, chronic nephritis does not have a concept of complete cure. Stage two patients indicate that the inflammatory reaction within the glomerulus is not very severe, but the patient may also show more proteinuria. In most cases, the renal function of these patients is still normal, and it may be necessary to decide whether to choose medications such as corticosteroids based on the amount of proteinuria. If the patient responds well to medication, the proteinuria may significantly decrease, or even turn negative, but it cannot be completely cured, as this is a chronic disease, and there is also a possibility of relapse in the later stages of the disease. (Please follow the doctor's orders regarding medication use.)
Precursors of relapse of nephrotic syndrome
Nephrotic syndrome is characterized by patients having 24-hour urinary protein quantification exceeding 3.5g and blood plasma albumin levels lower than 30g/L. This condition can be long-lasting. Some patients, after treatment, can have their condition effectively controlled, but there is still a possibility of relapse. Such relapses often occur after the patient has been overworked or has caught a cold, but there are also some patients who do not have such triggers. When the condition relapses, the urinary protein level increases again, which might lead to an increase in urine foam. Patients might experience significant swelling in the lower limbs and face among other areas, suggesting a relapse of nephrotic syndrome, and it is important to go to the hospital for relevant tests promptly.
Can kidney cancer patients eat eggs?
Patients with kidney cancer can eat eggs. Kidney cancer is a malignant tumor of the kidney, originating from the epithelial cells of the renal tubules. Although this disease is a malignant tumor, the patient's body still needs nutrients. Therefore, high-protein foods can be consumed by patients, and they should maintain a protein intake roughly the same as that of healthy individuals. Eggs are rich in protein, with each egg containing about seven to eight grams of protein. Kidney cancer patients can eat eggs without worsening their condition or causing the disease to spread. The folk saying that some foods are "stimulating" is not scientifically founded. Currently, there is no clear evidence in medicine to support the claim that eggs and beef are "stimulating."
What are the common symptoms of kidney cancer?
Kidney cancer is a malignant tumor of the renal parenchymal tissue. Some patients do not have specific symptoms, especially in the early stages. As the disease progresses, patients may find a mass in the abdomen. Some patients may experience back pain due to the enlargement of the kidney pressing against the renal capsule. Some patients experience bleeding due to the gradual rupture of the tumor, causing visible blood in the urine, which sometimes appears as painless throughout the blood in the urine. These symptoms may indicate the presence of a malignant tumor in the kidney, and diagnosis needs to be confirmed through ultrasound and CT scans.
Can chronic renal failure become pregnant?
Although patients with renal failure are not absolutely unable to become pregnant, pregnancy is ultimately a burden on the kidneys. Pregnant patients with renal failure may experience further deterioration of kidney function and may face numerous complications during pregnancy, such as heart failure, severe anemia, etc., which may pose some risks. However, there are still very rare case reports, including successful pregnancies in patients on dialysis for uremia, but the probability of this is extremely small, and the risks involved are too great. Generally speaking, it is not recommended for female patients with chronic renal failure to become pregnant.
Is diabetic nephropathy with facial swelling serious?
Patients with diabetic nephropathy who experience facial swelling should not use this symptom as a basis for judging the severity of their condition. Diabetic nephropathy is divided into five stages. The condition is relatively mild during the first three stages. By the fourth stage, patients begin to exhibit significant proteinuria, and by the fifth stage, they experience severe renal failure. Conditions in these last two stages are quite severe. However, patients might also experience facial swelling during the first three stages, and while the likelihood of facial swelling increases during the fourth and fifth stages, some patients in these stages might not show obvious edema. Therefore, it is difficult to determine the severity of the condition based solely on swelling. Patients need to undergo 24-hour urinary protein quantification and blood tests to assess kidney function in order to judge the severity of their condition.
