What should I do if I have hematuria due to urinary stones?
Urethral stones accompanied by hematuria mainly occur because the stones damage the mucosa and blood vessels of the urethra, causing blood in the urine. In such cases, one should first go to the hospital's urology department and undergo examinations such as color Doppler ultrasound and CT to determine the specific location and size of the stone, and then proceed with targeted treatment. If the stone is located in the posterior urethra, it is advised to push the stone back into the bladder using a cystoscope, then use a holmium laser under cystoscopic guidance to break the stone and expel it from the body. If the stone is located in the anterior urethra, it can be fragmented using a holmium laser through a ureteroscope and expelled, or a urethrotomy can be performed to remove the stone.
Is a prostate cyst serious?
Prostate cysts are not severe; they are a type of benign lesion primarily formed due to the blockage of prostate ducts. Most patients with prostate cysts have small cysts and do not experience any discomfort, and thus do not require treatment. Regular follow-up appointments to monitor changes in the size of the cyst are sufficient. It is advisable to maintain a light diet, avoid spicy and stimulating foods, and abstain from smoking and drinking, as these measures generally prevent the cyst from enlarging further. Of course, some patients may have larger cysts that could press on the urethra, leading to symptoms such as frequent urination, urgency, incomplete urination, and even difficulty in urination or urinary retention. In these cases, the cysts can be surgically removed proactively.
What should not be eaten with kidney stones
Patients with kidney stones do not have absolute dietary prohibitions. However, it is advisable to consume less food high in calcium, oxalates, and purines. Foods high in purines are mainly found in seafood, animal offal, beer, and beverages. High-calcium foods are primarily found in soy products and dairy products, such as soy milk, tofu, and cow's milk. Foods high in oxalates include celery, spinach, etc. These foods can be consumed in moderation in daily life, but should not be used in large amounts over a long period to avoid further growth and increase of stones. It is also important to drink plenty of water, urinate frequently, and engage in appropriate physical exercise to effectively prevent the occurrence of kidney stones. Additionally, for patients who have already developed kidney stones, it is necessary to timely decide on conservative stone expulsion or surgical treatment based on the size of the stones.
Clinical Manifestations of Renal Cancer
In the early stages of kidney cancer, most patients do not experience any discomfort symptoms, making it difficult to detect. As the tumor progresses to the middle and late stages and increases in size, it can cause symptoms of back pain. If the tumor breaches the renal pelvis, leading to ruptured blood vessels, this condition will be accompanied by obvious gross hematuria, which often appears intermittently and is painless. If the tumor is large, a mass can be felt in the back. If these symptoms arise, it is crucial to promptly visit the hospital's urology department for tests such as ultrasound and CT scans to establish a clear diagnosis. If necessary, active surgical intervention should be considered.
Can urethral stones cause back pain?
Urethral calculi refer to stones located within the urethra. The main clinical symptoms include frequent urination, urgency, and painful urination. Severe cases may present with hematuria and urinary retention. Generally, urethral stones do not cause back pain. If back pain occurs, it may be necessary to consider additional factors such as stones in the ureter or kidney, lumbar muscle strain, or herniated lumbar discs. Further examinations such as renal and ureteral color Doppler ultrasound, CT scans, and if necessary, lumbar disc CT scans should be conducted to determine if the back pain is caused by conditions outside of the urinary system. If the pain is due to stones, timely lithotripsy and stone expulsion treatments are required. If the cause is herniated lumbar discs, timely orthopedic treatment is necessary.
Can kidney cancer be diagnosed with a CT scan?
If you have kidney cancer, preoperative examinations, including ultrasound, CT, and even MRI, cannot definitively diagnose the cancer. These preoperative tests primarily provide diagnostic references. To confirm a diagnosis of kidney cancer, a biopsy via renal tumor puncture must be performed, or after surgery, the specimen should be sent for pathological examination to be definitively diagnosed based on the pathology results. This is because the pathology results clarify the type of tumor cells and their grading, making the pathological examination the final and most accurate diagnostic result.
How is stress urinary incontinence treated?
Stress urinary incontinence primarily occurs when activities like coughing, sneezing, lifting heavy objects, or jumping rope cause a sudden increase in negative pressure, leading to urine leakage from the urethral opening. For the treatment of stress urinary incontinence, it is important to determine the severity of the condition. For mild stress urinary incontinence, improvement can be achieved through exercises that strengthen the urinary sphincter and the pelvic floor muscles. For moderate to severe stress urinary incontinence, surgical intervention is recommended, mainly through mid-urethral sling procedures to manage urination. Patients should also take care to minimize activities that suddenly increase abdominal pressure, such as lifting heavy objects, laughing heartily, or sneezing.
Can frequent urination be diabetes?
If the amount of urine increases, the first thing to consider is the possibility of diabetes. In this case, a routine urine test will reveal a significant increase in urinary glucose. If a blood test for blood glucose is performed, an increase in blood glucose will also be found. For this situation, it is necessary to go to the hospital's endocrinology department for hypoglycemic treatment in a timely manner. Secondly, diabetes insipidus should be considered, which also causes an increase in urine volume, and the patient will have obvious thirst. Routine urine tests find that blood sugar in the urine is not high, the specific gravity of urine will initially decrease, and the patient's daily urine output will exceed 2500 milliliters, even reaching more than 4000 milliliters.
Can urethral stones cause urgent urination?
Urethral stones can cause symptoms of urinary urgency because the stones stimulate the urethra, causing urgency. In addition to urgency, symptoms include frequent urination and painful urination, and in severe cases, blood in the urine may occur. If the stone is relatively large, it can block the urethra, leading to symptoms of urinary retention. If suffering from urethral stones, it is necessary to go to the hospital's urology department for ultrasound and CT scans of the urinary system to understand the specific size and location of the stones in the urethra, and to carry out targeted treatment. If the stones are small, they can be expelled from the body by drinking more water and urinating frequently, relying on the flushing action of the urine. If the stones are large, it is recommended to undergo surgery as soon as possible.
Should I wear diapers for urinary incontinence?
Whether patients with urinary incontinence need to use diapers should be determined based on the severity of the incontinence. If it is only mild incontinence that does not affect normal work and life, it is not necessary to wear diapers. Regular urination schedules, along with exercises like pelvic lift and pelvic floor muscle training, can alleviate the condition. However, if the incontinence is more pronounced, it is best to initially use diapers to prevent excessive urine leakage. If necessary, a urinary catheter can be used temporarily to drain the urine and prevent leakage. At the same time, it is important to actively undergo relevant examinations to determine the cause of the incontinence and carry out targeted treatment.
