Treatment of bladder cancer
For the treatment of bladder cancer, it is necessary first to confirm the diagnosis of bladder cancer through routine urine tests, ultrasonographic examination of the urinary system, cystoscopy, and imaging studies of the urinary system. It is important to determine the location, area, and malignancy of the bladder tumor. For early-stage superficial bladder tumors or tumors on the bladder wall with fewer numbers, minimally invasive surgery can be performed, followed by bladder perfusion to prevent recurrence of the bladder tumor. In the second scenario, if the bladder tumor is multiple and larger, and has a higher degree of malignancy in the bladder trigone area, then a radical cystectomy is required. Radical cystectomy involves the removal of the bladder along with the prostate in males or the uterus in females, followed by the creation of a urinary diversion, typically through these two treatment methods.
How to treat cystitis
Bladder infections are most commonly seen in female patients, as the female urethra is very close to the vagina and anus, making it easy for bacteria to cause infection. Symptoms of bladder infection generally include frequent urination, urgent need to urinate, painful urination, discomfort in the bladder area and perineum, a burning sensation during urination, and sometimes visible blood in the urine at the end of urinating. Diagnosis of bladder infection mainly involves a routine urine test, where a large number of white blood cells can be seen in the urine. In terms of treatment, antibiotics are primarily used, with quinolones such as levofloxacin being common choices, administered over three days. Another option is cephalosporin antibiotics such as cefixime, which is also used for three days. It is important to drink plenty of water, urinate frequently, avoid spicy and irritating foods, and maintain cleanliness and hygiene of the perineal area. Generally, symptoms should improve significantly within about three days, and it is advisable to recheck the routine urine test after one week.
What does prostate cyst mean?
Prostate cysts occur due to congenital or acquired cystic changes in the prostate gland. Small prostate cysts usually do not exhibit any symptoms. However, if an infection or stones are present, it can lead to symptoms such as frequent urination, urinary urgency, strained urination, and a feeling of incomplete bladder emptying. When the prostate cyst is large, it can compress the urethra or the neck of the bladder, obstructing urine flow, which may lead to frequent urination, urgency, difficulty in urinating, a thin urine stream, and even urinary retention. Additionally, it may compress the rectum, causing difficulty in defecation. If the prostate cyst is asymptomatic, no treatment is necessary. Surgical treatment may be considered for large or symptomatic prostate cysts, or treatment could be administered via transrectal prostate cyst puncture.
Is there a treatment method for prostate cysts?
Prostate cysts are a benign condition of the prostate, generally discovered during ultrasonic examinations of the urinary system. The treatment for prostate cysts primarily depends on the size of the cyst and whether it can cause related symptoms. If the prostate cyst is small and asymptomatic, it may not require treatment. However, if the cyst is large, it can compress the bladder, leading to urethral blockage, and cause symptoms like difficulty urinating, frequent urination, urgency, or even urinary retention, and can also compress the rectum causing difficulty in defecation. In such cases where these symptoms are present, surgical treatment is needed. There are two types of surgeries: one is the percutaneous treatment of the prostate cyst and the other is transurethral resection of the prostate.
What should I do if I have hematuria due to urethral stones?
For urethral stones, if hematuria occurs, the size of the urethral stones should be first considered. Generally, urethral stones are caused by kidney stones or ureter stones that move to and become lodged in the urethra, with the main symptoms being blood in the urine, difficulty urinating, and even urinary retention. If the urethral stone is relatively small, exercising more and drinking more water usually can help in expelling the stones out of the body; this generally applies to stones smaller than four millimeters. If the stone is larger and cannot be expelled, it is recommended to undergo cystoscopy to push the stone back into the bladder to be broken up and removed, or to directly remove the stone through the urethra. Additionally, if the stone is very close to the external opening of the urethra, it can also be removed using hemostatic forceps to clamp out the urethral stone.
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.
