What is the best treatment for kidney stones?
The treatment methods for kidney stones vary based on the size of the stone and whether it causes obstruction. If the kidney stone is relatively small and can pass through the ureter and urethra on its own, no special treatment is needed. In such cases, drinking more water, urinating frequently, and jumping can help the stone to pass naturally. If the kidney stone is relatively large but does not cause obstruction in the kidney or bladder, these patients can be temporarily observed with regular check-ups to monitor the stone's condition, without needing special treatment. Only when a large stone gets stuck at the junction of the renal pelvis, ureter, or urethra during its passage does it cause urinary obstruction, and the patient may also experience pain. In such cases, the treatment generally involves surgically removing the stone.
Early symptoms of kidney stones in women
The initial symptoms of kidney stones in women vary depending on the size of the stone and whether the stone causes an obstruction. Generally, during the early stages of kidney stones, the stones are relatively small and do not cause obstruction in the kidney or bladder, and typically do not present any symptoms. However, if a small stone moves downward and accidentally gets stuck in a naturally narrow part of the ureter, it can cause symptoms such as pain and discomfort in the lower back, nausea, and vomiting. If the stone gets stuck at the junction of the ureter and the bladder, it irritates the bladder mucosa, leading to symptoms of frequent urination, urgent urination, and painful urination. However, small stones generally pass on their own. Analgesics can be used for symptomatic treatment. Additionally, medications that dilate the ureter, along with drinking plenty of water and physical activity such as jumping, generally help the stone to pass.
What is the difference between genuine urinary incontinence and pseudo urinary incontinence?
Genuine urinary incontinence generally occurs due to incomplete closure of the urethral sphincter, or due to insufficient urethral closure pressure. As a result, patients will show continuous leakage of urine from the urethra or involuntary urine discharge from the urethra when there is an increase in intra-abdominal pressure, such as during sneezing, coughing, or performing strenuous physical activities. Genuine urinary incontinence includes both continuous and stress urinary incontinence. Pseudo urinary incontinence is generally due to urethral stricture, commonly seen with conditions such as prostatic hyperplasia or urethral stones. The urethral stricture prevents urine from being expelled from the bladder. When the bladder becomes overly full, urine overflows through the urethra, a condition also known as overflow incontinence.
What are the symptoms of kidney stones?
The symptoms of kidney stones vary depending on the size of the stones and whether they cause obstruction. If the stones are relatively small, they can usually pass smoothly through the ureters and urethra and be expelled from the body without causing any symptoms. When the stones are expelled, small stones can be seen in the urine. If the kidney stones are relatively large but do not cause obstruction in the kidneys or bladder, they generally do not cause any symptoms. Symptoms occur only when larger stones move downward and become lodged in the ureters, causing back pain, nausea, and vomiting. The stones can scratch the walls of the ureters, leading to blood in the urine. When stones get stuck in the urethra, it can cause painful urination discomfort and perineal pain. Since the stones can scratch the inner walls of the urethra, they may also cause blood in the urine.
How to relieve pain from hydronephrosis
Hydronephrosis accompanied by pain is generally caused by kidney stones lodged in the ureter leading to renal colic, and the stones in the ureter can cause urinary obstruction, thus presenting as hydronephrosis. To alleviate the pain in such cases, treatment methods are chosen based on the size of the stone. If the kidney stone is relatively small and estimated to be able to pass by itself into the bladder, temporary use of pain relief medication can be administered for symptomatic treatment, along with medication that dilates the ureter to expand its diameter, facilitating the expulsion of the stone. If the stone is large and predicted not to pass on its own, temporary symptomatic treatment with pain relief medication can be used. Meanwhile, after completing preoperative examinations, surgery can be performed to remove the stone, which can also completely alleviate the pain symptoms.
Can you wear diapers for urinary incontinence?
Urinary incontinence generally requires the use of diapers, as the condition is primarily caused by various pathological changes, leading to the involuntary discharge of urine from the urethra. Due to the easy infiltration of the perineum and around the urethral opening by urine, there might be occurrences of eczema or perineal infections. Wearing diapers can timely absorb the leaked urine, thereby reducing the chances of developing eczema and perineal infections. It is also necessary to actively seek the underlying cause of urinary incontinence and treat it accordingly. Common types of urinary incontinence include persistent, stress-related, overflow, and urge incontinence. By conducting thorough examinations, the specific type of urinary incontinence can be identified, followed by targeted treatment.
Can urine odor be a sign of bladder cancer?
Urine with an unusual odor may be caused by bladder cancer, but the presence of an odor alone cannot be used to diagnose bladder cancer. Clinically, urine with an odor is commonly associated with urinary tract infections, as patients with such infections tend to have a higher amount of inflammatory secretions in their urine. Additionally, patients with urinary tract infections may lose some body water through sweating, leading to more concentrated urine, which can increase the odor. Bladder cancer patients are more susceptible to urinary tract infections, so they may also experience odorous urine. Clinically, bladder cancer is diagnosed through a combination of the patient's symptoms and supportive diagnostic tests. In the early stages of the disease, bladder cancer typically presents as painless hematuria (blood in the urine) that persists for an extended period. A routine urinalysis can be performed to check for elevated red blood cells in the urine. If bladder cancer is suspected, a cystoscopy can be conducted to identify any masses in the bladder and take biopsy samples for pathological examination. The presence of tumor cells in these samples generally confirms a diagnosis of bladder cancer.
Can I occasionally drink a bottle of red wine with chronic prostatitis?
Patients with chronic prostatitis should not drink red wine. Chronic prostatitis has a long course of disease, mainly characterized by frequent urination, urgency, and painful urination. After urinating, a small amount of white secretion may drip out. Patients may also experience discomfort or pain in the pubic or perineal area. In some severe cases, there might be a decline in sexual function, manifesting as erectile dysfunction or premature ejaculation. Patients with chronic prostatitis generally need to use anti-inflammatory drugs that have a strong ability to penetrate the prostatic capsule, such as erythromycin and doxycycline. During the treatment period, patients should not drink alcohol, sit for long periods, or ride bicycles for an extended time. Treatment can also be complemented with sitz baths and prostate massage. (Please use medication under the guidance of a doctor.)
How to care for incontinence-associated dermatitis
The care for incontinence-associated dermatitis primarily involves keeping the affected skin clean and dry. It is important to avoid skin contact with urine as much as possible. If the skin does come into contact with urine, it should be washed promptly and kept clean and dry. If there is itching or discomfort at the site of the dermatitis, topical corticosteroid ointments may be used to alleviate the itching. Some patients might also develop infections, typically bacterial, which can be managed with antibiotics. For patients with recurrent dermatitis, considering bladder fistulation or other treatment methods might be necessary to prevent skin contact with urine.
Is nonbacterial prostatitis easy to treat?
Sterile prostatitis is generally difficult to treat, with most cases presenting as chronic alterations, also known as chronic prostatitis. These patients show symptoms of prostatitis even though no bacteria are found in the prostate fluid. Symptoms include frequent, urgent, and painful urination, and a white discharge may drip from the urethral opening after urinating. Treatment generally involves symptomatic management. If pain symptoms are significant, pain relief medication may be necessary. Some patients may experience anxiety symptoms due to the long-term nature of the condition, requiring the use of anti-anxiety medications. Additional supportive treatments might include warm sitz baths or prostate massage, usually extending over a long treatment period.
