Can kidney cancer that has spread to the lungs be cured?
Kidney cancer usually reaches an advanced stage by the time it metastasizes to the lungs, leading to a generally low survival rate. For early and intermediate-stage kidney cancer patients, surgical treatment is typically employed. However, in advanced stages, especially when there are lung metastases, surgical methods are often not suitable. However, if the metastatic foci are small, it is still recommended to remove them surgically. Immunotherapy can be used for lung metastases, such as using interferon or targeted therapy. Targeted therapy tends to be effective, commonly using drugs like sorafenib and sunitinib for first-line or second-line treatment of metastatic kidney cancer. Although a complete cure is not possible, these treatments can significantly prolong the patient's lifespan, improve survival rates, and alleviate symptoms.
What is good to eat after kidney cancer surgery?
If kidney cancer is detected early, it can be cured through surgery. Unlike some malignant tumors, kidney cancer has good treatment outcomes. If the cancer is less than four centimeters in diameter, the five-year survival rate after surgery can exceed 90%. If it is less than seven centimeters, the five-year survival rate after surgery can also reach 80%. Even if the cancer has metastasized to distant sites, removing the kidney can still help the patient's survival. Therefore, the earlier the tumor is detected, the better the treatment outcomes. Kidney cancer surgery is generally done through laparoscopy or open surgery. Postoperative diet should be high in protein, fiber, and nutrients, as the healing of the kidney cancer incision also requires a solid nutritional foundation. It is necessary to eat less spicy and stimulating food, and to maintain a low-salt, low-fat diet. The most important thing for kidney cancer is to have regular follow-ups to understand the recovery situation and check for any recurrence or metastasis of the tumor.
What should be paid attention to with bladder stones?
Bladder stones are stones formed inside the bladder, including both primary and secondary bladder stones. The typical symptoms of bladder stones are pain and hematuria, often accompanied by interrupted urine flow, which is a distinctive manifestation of bladder stones. Through ultrasound examination of the urinary system, the size, shape, and number of stones inside the bladder can be detected. For the treatment of bladder stones, small stones can typically pass through the urethra on their own, generally if they are less than 0.6 centimeters. Larger bladder stones can be treated with intravesical lithotripsy. Methods of lithotripsy include extracorporeal shock wave lithotripsy and transurethral lithotripsy to break and remove the stones. Additionally, individuals with bladder stones should drink plenty of water, urinate frequently, and avoid spicy and irritating foods.
Can a prostate cyst cause lower abdominal pain?
Simple prostate cysts generally have no symptoms. Larger prostate cysts may compress the urethra, causing difficulty in urination, and pressure on the rectum may cause difficulty in defecation. If prostate cysts are accompanied by prostatitis, this can cause lower abdominal pain. Pain may not only be in the lower abdomen, but can also occur in the lumbosacral area, perineum, groin area, and testicles, presenting symptoms of discomfort. There may also be abnormalities in urination, such as increased frequency of urination, urgency, incomplete urination, increased nocturia, split stream, difficulty urinating, and waiting for urine flow, among other symptoms. Therefore, if lower abdominal pain occurs with a prostate cyst, it is worth considering its association with prostatitis, and treatment can be administered accordingly based on methods used for prostatitis.
Which department should I go to for kidney stones?
Kidney stones should be treated by a urologist. For kidney stones, a urology department will perform an ultrasound of the urinary system to examine them. The symptoms of kidney stones mainly depend on the size, shape, and location of the stones, as well as the presence of any obstructions or complications such as infections. Smaller kidney stones often do not cause any symptoms in patients unless the stone falls into the ureter, which can cause acute renal colic, severe lumbar and abdominal pain, and sometimes nausea, vomiting, frequent urination, urgency, and hematuria. If kidney stones are accompanied by a urinary obstruction or infection, patients may experience persistent high fever. If the kidneys have multiple columnar stones, it can lead to impaired renal function and cause renal insufficiency. Therefore, kidney stones should be taken seriously. If the stones are relatively large, consider surgical treatment or lithotripsy.
Kidney stone symptoms
The symptoms of kidney stones depend on the size and shape of the stone, as well as its location in the kidney, whether there are infections, obstructions, and other factors. Smaller kidney stones, which are smooth, can be expelled with the urine without causing noticeable symptoms. Stones lodged in the lower part of the renal pelvis or in the calyces can be asymptomatic. If the kidney stones are larger, located in the calyces or the renal pelvis, they can compress the kidney and cause back pain or dull pain because the stones can lead to the dilation or obstruction of the renal pelvis or kidney. Patients may experience back pain, fever, and if there is an infection, localized fever may occur. Additionally, kidney stones can scratch the mucous membrane of the ureter or kidney, causing bleeding.
Is bladder cancer hereditary?
Bladder cancer is the most common malignant tumor in urology, occurring on the mucosa of the bladder and is also one of the top ten common tumors globally. The etiology of bladder cancer is complex, involving both intrinsic genetic factors and external environmental factors, which gives bladder cancer a hereditary tendency. Notable among the major risk factors are smoking and occupational exposure to aromatic amines, with 30% to 50% of bladder cancers caused by smoking. The incidence of bladder cancer significantly increases with the duration of smoking. The initial clinical manifestation of bladder cancer is usually hematuria, typically painless and intermittent gross hematuria. The presence of blood in urine should prompt further diagnostic testing to rule out malignant tumors in the bladder.
Is there a problem with a prostatic cyst?
Smaller prostate cysts generally do not affect the body or urine excretion, and treatment may not be necessary in such cases. However, if a prostate cyst becomes infected, develops stones, or is large enough to compress the urethra or bladder neck, it can obstruct urine flow, commonly causing difficulty urinating or even urinary retention. Compression of the rectum can also lead to difficulties in both urination and defecation. Therefore, small prostate cysts may not require intervention, but larger ones with compressive symptoms need surgical treatment. In cases of infection, symptomatic treatment is sufficient. The diagnosis of prostate cysts is usually confirmed through ultrasound examination of the urinary system. For larger cysts, typical surgical options include ultrasound-guided puncture or transurethral resection of the prostate cyst.
Is prostatic calculus easy to treat?
Prostate stones are formed in the prostate acini and ducts. Most patients with prostate stones do not have any symptoms. Some patients may have concurrent prostatitis or prostate hyperplasia, resulting in abnormal urination. The main symptoms include frequent urination, urgent urination, difficulty urinating, hematuria, residual urine, along with discomfort in the lumbar and sacral regions, perineal discomfort, and sexual dysfunction. If prostate stones are asymptomatic, treatment is not required. However, if there are symptoms like abnormal urination or pain, treatment can be administered through medications. Broad-spectrum antibiotics such as levofloxacin are commonly used for about four weeks. Additionally, it is advisable to adhere to warm water sitz baths daily for 20 minutes to accelerate blood circulation in the prostate and improve symptoms. It is also recommended to avoid spicy and irritating foods, refrain from prolonged sitting, avoid holding in urine, and maintain a regular sexual life.
Is urethral calculus the same as kidney stones?
Urethral calculi and kidney stones are not the same concept. Urethral calculi refer to stones located in the urethra, while kidney stones are stones located within the kidney. The cause of urethral calculi is usually due to stones from the kidney or ureter becoming lodged in the urethra, which clinically often results in symptoms such as frequent urination, urgent urination, and difficulty urinating. Severe cases may lead to urinary retention. If kidney stones are small and smooth, they may not cause any symptoms. However, larger kidney stones can cause localized back pain, and if infected, may also lead to high fever. The treatment methods for kidney stones and urethral calculi are also different. Urethral calculi can generally be removed through surgery or endoscopic methods, while the treatment for kidney stones depends on the size and location of the stones.
