How is hydronephrosis diagnosed?
Strictly speaking, hydronephrosis cannot be considered an independent disease; it is merely a descriptive term in imaging, and is the result of many causes and various etiologies. It occurs because urine produced by the kidneys cannot smoothly pass through the ureters and bladder to be excreted from the body, leading to fluid accumulation in the renal pelvis and calyces. This may be caused by prostate enlargement, tumors in the urinary system, urinary system stones, or chronic inflammation and scarring of the ureters. Generally, hydronephrosis can be detected through imaging techniques, including urinary system ultrasound or CT, which can confirm the diagnosis.
Can people with nephrotic syndrome eat strawberries?
Patients with nephrotic syndrome can eat strawberries in moderate amounts. Patients with nephrotic syndrome typically have urinary protein levels exceeding 3.5g in 24 hours, along with noticeable symptoms of edema. It is essential for these patients to control their intake of water, especially those with severe edema, as excessive water intake can further exacerbate the swelling. Additionally, patients should limit their intake of plant proteins, follow a low-salt diet, and avoid heavy consumption of oils and fatty foods. From the above perspectives, it is generally acceptable for patients with nephrotic syndrome to eat strawberries in moderation. Strawberries contain very little plant protein and will not increase urinary protein levels. Although strawberries do not contain much salt, patients with nephrotic syndrome still need to consume them in moderation due to their high water content.
Can chronic renal failure reproduce?
Patients with chronic renal failure, if they are male, can attempt to conceive under the guidance of a clinic doctor after discontinuing the use of medications that affect fertility; usually, there are no major issues for male patients. However, for female patients, attempting to get pregnant carries a significant risk because pregnancy increases the burden on all organs, including the kidneys, which can exacerbate kidney diseases, especially in cases like lupus nephritis. Nevertheless, not all patients with chronic renal failure are absolutely unable to conceive; some have successfully managed the risks associated with pregnancy. In such cases, it is necessary to weigh the pros and cons.
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."
