Is hydronephrosis serious?
Whether the condition of hydronephrosis is serious depends on various factors such as the duration of hydronephrosis, the cause, the extent of fluid accumulation, and more. For example, some patients may have mild hydronephrosis in only one kidney and it may have developed recently; generally, this condition is not very serious. Some patients might have urinary obstructions caused by urinary system stones, and the issue could be resolved using extracorporeal shock wave lithotripsy or surgical stone removal, making the condition not serious. However, in some cases, the cause could be bladder cancer or a tumor near the urinary system compressing the ureter, and if the tumor is difficult to remove, the hydronephrosis might be hard to manage. Long-term fluid accumulation might lead to kidney failure, and these scenarios are considered quite serious.
Is allergic purpura nephritis contagious?
Henoch-Schönlein purpura nephritis and allergic purpura are not infectious diseases; there is no contagious element involved. Henoch-Schönlein purpura nephritis is actually kidney damage caused by allergic purpura, which is an allergic disease itself. Patients suffer from an abnormal immune response in the body’s immune system after coming into contact with allergenic drugs or foods, leading to necrotizing vasculitis. This disease is unrelated to pathogens. Generally, there is no direct damage to the kidneys caused by a specific pathogen in this disease, nor do patients carry pathogens that can cause Henoch-Schönlein purpura nephritis, such as bacteria or viruses, thus making the disease non-contagious.
IgA nephropathy is a kidney disease.
In medical terms, there is a condition named IgA nephropathy. IgA is actually a type of immunoglobulin. The function of immunoglobulins is to bind with antigens, which then induces an inflammatory response. For example, when bacteria enter the human body, the combination of IgA with the bacteria guides the body's immune system to target and attack the bacteria, which is a normal scenario. This IgA immunoglobulin acts as a mediator in the immune response. Due to some defect, this substance accumulates in the glomeruli. Its deposition in the glomerular capillaries can trigger inflammation in these blood vessels, leading to IgA nephropathy. This results in proliferation of glomerular mesangial cells, deposition in the mesangial matrix, causing blood and protein in the urine, and even leading to renal failure.
What are the symptoms of acute nephritis?
All patients with acute nephritis will have abnormalities in routine urinalysis, presenting with hematuria or proteinuria, or both concurrently. However, the severity of the condition varies. Some patients may have a large number of red blood cells in their urine, resulting in gross hematuria, tea-colored urine, light red urine, or urine resembling washed meat. Patients might also experience an increase in urine foam due to a large amount of urinary protein. Additionally, patients may develop acute renal failure, during which they might experience a decrease in urine output. However, all mentioned conditions can gradually improve over the course of three to four weeks, with increases in urine output, normalization of routine urinalysis, and resolution of edema.
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.
What medicine is used for chronic renal failure?
The treatment of chronic renal failure primarily requires identifying the cause and treating it accordingly. Chronic renal failure refers to the state in which various diseases damage the kidneys, leading to the destruction of kidney tissue and resulting in the kidneys' inability to adequately excrete metabolic waste, causing an accumulation of such wastes in the body. There are no medications that can directly affect the kidneys, regenerate kidney tissue, and restore kidney function. Currently, medicine cannot achieve this, and there are no specific drugs for the treatment. Therefore, the treatment of chronic renal failure focuses on treating the primary disease to slow the progression of renal failure. For example, chronic renal failure caused by diabetes necessitates the use of insulin to control blood sugar, while patients with hypertension need to use antihypertensive drugs.
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 to do if nephrotic syndrome causes leg pain?
Patients with nephrotic syndrome who experience leg pain mostly have conditions unrelated to nephrotic syndrome itself. It could be due to diseases of the skeletal or muscular system. However, some patients might experience leg pain due to thrombosis caused by nephrotic syndrome, leading to ischemia in the limbs. Also, long-term use of corticosteroids can lead to necrosis of the femoral head, osteoporosis, and pain. Therefore, treatment should be targeted based on the cause, such as using drugs to dissolve clots or interventional surgery for those with thrombosis. In severe cases of femoral head necrosis, a femoral head replacement surgery might be necessary, and it is important to supplement with calcium regularly.
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.
