Can holding urine cause uremia?
Generally speaking, holding urine does not lead to uremia, but if the bladder is overfilled, it can result in an inability to urinate. This can lead to acute renal dysfunction. After catheterization, the indicators of renal function can quickly return to normal. Therefore, we should try to avoid holding urine as much as possible and go to the bathroom promptly when we need to. This is something we should pay attention to in our daily lives.
What is the best treatment for kidney stones?
Kidney stones are generally treated by drinking a lot of water. Smaller stones may be expelled due to the push of a large volume of urine. Secondly, antispasmodic analgesics like M-type cholinergic receptor blockers can be used to relax the ureteral smooth muscle and alleviate spasms. Thirdly, controlling infection is crucial because urinary tract obstructions caused by stones are prone to infections, and infections often lead to the formation of struvite stones, perpetuating a vicious cycle that exacerbates the condition. It is essential to actively remove obstructions caused by stones and use antibiotics for prevention. Fourth, surgical treatment should be considered when pain cannot be alleviated by medication or when the stone is too large.
Can kidney cancer patients eat sea cucumber?
Patients with kidney cancer can eat sea cucumber, but the amount should be determined based on individual conditions. It is recommended not to exceed 30-50 grams per day to avoid side effects. Consuming sea cucumber in moderation is advisable, as excessive seafood and high protein can increase the burden on the kidneys. Therefore, the specific amount should be determined according to the patient's kidney function, creatinine, and urea nitrogen levels.
Dietary precautions for renal cancer
Kidney cancer patients should be cautious with their diet and there are three types of food they should absolutely avoid: First, foods high in salt. Kidney cancer patients often suffer from severe kidney dysfunction, leading to edema. Consuming salty foods can increase the body's sodium content, causing sodium retention which is not metabolized in time, exacerbating the swelling. Second, high-fat foods. Excessive fat can also lead to weight gain, and high body fat can burden the kidneys. Third, foods high in potassium. With kidney cancer, patients often have inadequate kidney function and produce less urine, leading to high levels of potassium in the body. Consuming foods high in potassium can further increase blood potassium levels. Therefore, it's advisable for kidney cancer patients to avoid fruits and vegetables high in potassium.
Causes of Renal Cancer
The cause of kidney cancer is unknown, but possible factors include: First, smoking, which is a relative risk factor for kidney cancer. Second, obesity and hypertension. Third, occupation, with reports indicating that long-term exposure to metallic lead, print industry workers, coke workers, and workers shows increased risks of incidence and mortality from kidney cancer. Fourth, radiation, where long-term exposure to certain sources of radiation may increase the risk of kidney cancer. Fifth, there is a certain relation to genetics. Sixth, dietary factors, as studies have found that high intake of dairy products, animal protein, and fat, and low intake of fruits and vegetables, are also risk factors for kidney cancer.
The difference between benign and malignant kidney cancer.
The incidence of kidney cancer is also considered relatively high, with over 95% of kidney tumors being malignant, and benign tumors being less common. The distinction between benign and malignant tumors is determined by their symptomatic expression and growth patterns, and they have different impacts on the body. Generally, benign tumors grow expansively or exophytically, have a slower growth rate, and have clearer boundaries with often a capsule surrounding them. The texture and color of the tumor are close to that of normal tissues. Malignant tumors, on the other hand, exhibit the opposite characteristics.
Is kidney cancer prone to metastasis?
Kidney cancer in its early stages generally does not metastasize. If it does metastasize, it usually follows several paths: one is hematogenous or lymphatic spread, followed by local diffusion, and then the tumor invades surrounding fat or blood vessels, which is local diffusion. It is also important to note that there is a pseudo-capsule around the kidney cancer that prevents the spread of cancer cells. Metastasis is not likely when the tumor is small, but as the tumor size increases or in some special types of tumor cells, metastasis may occur.
What should be paid attention to in the diet for bladder stones?
If the bladder stones are oxalate stones, to prevent their formation, one should avoid eating foods high in oxalates, such as spinach, mushrooms, potatoes, strong tea, coffee, chocolate, etc. If the stones are urate, one should reduce the intake of foods high in uric acid, such as animal offal and seafood. It is important to drink more water regularly to develop a good habit of hydration, as increased water intake can dilute the urine crystals, making it easier for stones to be expelled from the body. Thirdly, eat less high-fat food and avoid high-cholesterol foods, such as animal offal, abstain from smoking and drinking, and reduce meat consumption.
How is cystitis diagnosed?
Chronic cystitis can be diagnosed through various methods. Firstly, urinary tract imaging can demonstrate reduced bladder capacity, rough or irregular bladder margins. Secondly, an ultrasound can show a reduction in bladder cavity and general thickening of the bladder wall. Additionally, a CT scan can reveal widespread irregular thickening of the bladder wall and a reduction in bladder size, with the inner and outer surfaces appearing rough. These diagnostic methods can all be used to check for cystitis, though specific situations should be evaluated on a case-by-case basis.
Clinical manifestations of bladder stones
Generally speaking, a typical clinical manifestation of bladder stones is the sudden interruption of urination. That is, the patient may start to urinate normally, but then suddenly becomes unable to urinate midway through. Urination can resume once the patient changes position. Therefore, this sudden interruption of urination is a classic symptom of bladder stones. Of course, bladder stones can also cause other urinary tract irritation symptoms, such as frequent urination, urgency, pain during urination, and hematuria (blood in urine).
