Is stage II kidney cancer considered early stage?
The staging of kidney cancer is primarily based on the size of the tumor, whether there is lymph node metastasis, involvement of adjacent organs or lymphatic vessels, and metastasis to distant organs. The TNM staging system is commonly used in clinical settings to stage kidney cancer, where "T" represents the depth of tumor invasion, "N" represents the status of lymph node metastasis, and "M" represents distant metastasis. Stage II refers to a tumor with a maximum diameter greater than seven centimeters but confined to the kidney. Stage II is further divided into stage IIA and stage IIB. Stage IIA refers to a tumor with a maximum diameter greater than seven centimeters but less than ten centimeters, confined to the kidney. Stage IIB refers to a tumor with a maximum diameter greater than ten centimeters, but still confined to the kidney. In the case of stage II kidney cancer, although it is an early stage, curative treatment can be achieved through surgery. Therefore, if diagnosed with stage II kidney cancer, it is vital to pursue aggressive treatment.
Can prostate stones be eliminated?
Prostate stones are stones formed in the ducts or acini of the prostate, and their occurrence is somewhat related to the blockage of these ducts. Prostate stones generally do not exhibit obvious symptoms. However, accompanying conditions such as prostate hyperplasia or prostatitis can lead to abnormal urination. The main clinical symptoms include frequent urination, urgent urination, incomplete emptying, increased nocturia, and difficulty urinating. Accompanied by chronic prostatitis, there may also be discomfort in the lumbar and perineal regions, potentially leading to sexual dysfunction in patients. Larger prostate stones can cause urinary retention and press on the rectum, resulting in difficulty defecating. In general, prostate stones are difficult to expel from the body. Symptomatic treatment is usually sufficient, but surgical treatment might be considered for particularly large stones.
Can prostate cysts heal by themselves?
Prostatic cysts generally cannot heal on their own. They are cystic expansions within the prostatic ducts or acini. If a prostatic cyst is small, it typically does not cause any symptoms or harm to the body, and regular follow-up is sufficient. However, if a prostatic cyst is large, it can compress the urethra, leading to difficulty urinating or even urinary retention. If it presses on the rectum, it can also cause difficulty defecating. Larger prostatic cysts that cause symptoms may require surgical treatment, which can be done through open surgery or transurethrally to remove the cyst. Therefore, if a prostatic cyst is asymptomatic, it does not need treatment; if it is large and symptomatic, surgical treatment can be considered.
Is bladder cancer scary?
Bladder cancer is the most common malignant tumor in urological surgery, primarily occurring in the bladder mucosa. Its symptoms include painless, intermittent gross hematuria, with nearly 100% of patients experiencing blood in the urine. The presence of hematuria should highly raise the suspicion of bladder cancer, and the examinations mainly include routine urinalysis and an ultrasound of the urinary system. Bladder cancer is not to be feared if it is detected and treated early. The surgery can be relatively simple, and minimally invasive treatment through the urethra, such as plasma electrosection or laser excision, is possible. Since bladder cancer can recur, postoperative management should include bladder perfusion therapy and regular cystoscopy re-examinations. Thus, bladder cancer is not to be feared, as early detection and treatment can lead to a cure.
Can prostate stones be removed?
Prostate stones are typically very small and do not cause any discomfort to the patient. However, if accompanied by conditions such as prostate enlargement or prostatitis, urinary abnormalities such as frequent urination, urgency, terminal hematuria, and difficulty urinating may occur. In the usual treatment of prostate stones, if symptoms are present, they are mostly caused by prostatitis. Treating the prostatitis is sufficient, and it is not necessary to remove the stones. However, if the prostate stones are very large, traditional open surgery, which involves the removal of prostate stones through the urethra, can be used. This is generally suitable for younger patients. It is often difficult to remove prostate stones, but a similar effect can generally be achieved through minimally invasive surgery.
