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.
How is prostatitis treated?
Prostatitis is divided into acute prostatitis and chronic prostatitis. Acute prostatitis is generally caused by bacterial infection of the prostate, so antibiotics are needed to control the infection. Additionally, patients with acute prostatitis often experience pain and fever, thus requiring antipyretic analgesics for symptomatic treatment. Chronic prostatitis has a longer duration and is divided into bacterial prostatitis and nonbacterial prostatitis. Bacterial prostatitis generally requires treatment with antibiotics, and those that can penetrate the prostate capsule are preferred. Patients with chronic prostatitis can also benefit from warm sitz baths and prostate massage as auxiliary treatments. During treatment, the diet should be light, avoiding spicy and stimulating foods, avoiding prolonged sitting, and abstaining from alcohol.
Is minimally invasive sling surgery for urinary incontinence permanent?
Minimally invasive sling surgery is generally suitable for patients with stress urinary incontinence. This surgery is usually not permanent, and its specific name is tension-free urethral suspension. It is used to increase the closure pressure of the urethra. Therefore, when the intra-abdominal pressure increases, the increased urethral closure pressure can prevent urine leakage. This surgery is one of the more common surgeries in clinical practice, but over time, various complications related to the surgery tend to increase. Common surgical complications include difficulty urinating, bladder perforation, and corrosion of the vaginal or urethral sling. Over time, the probability of corrosion gradually increases.
How much water should a patient with urinary incontinence drink each day?
Patients with urinary incontinence generally need a daily water intake of about 1000 to 2000 milliliters. Although those suffering from urinary incontinence may involuntarily excrete urine from the urethra, their water intake needs to be the same as that of normal individuals. Drinking more water is beneficial for the body, as it increases urine production, which can dilute the concentration of stone-forming substances in the urine, thus reducing the likelihood of developing urinary stones. Increased urine production due to higher water intake can promptly flush the urinary tract, especially washing away bacteria on the urethra, thereby reducing the chances of urinary tract infections. Furthermore, drinking more water increases urine production and promptly excretes metabolic waste products produced in the body through the urine, thus preventing the accumulation of metabolic products.
How to relieve nausea caused by hydronephrosis?
Hydronephrosis with nausea can be caused by various reasons, so alleviating nausea symptoms requires specific analysis based on the specific cause. Patients with hydronephrosis often seen in hospital beds are mostly those with ureteral stones. When the stone is lodged in the ureter, the patient will experience an obstruction of urine outflow, leading to hydronephrosis. Moreover, a stone stuck in the ureter can cause renal colic, manifested as back pain, and may also be accompanied by symptoms of nausea and vomiting. In such cases, treatment methods depend on the size of the stone; if the stone is relatively small, it can often be passed naturally with increased water intake and conservative treatment. If the stone is large, it generally requires surgical removal. Hydronephrosis can also result from prolonged obstruction leading to impaired kidney function and uremia. In these situations, it's usually necessary to promptly relieve the urinary obstruction, maintain urethral patency, and, if the patient has elevated blood creatinine levels, employ dialysis or other methods to bring creatinine back to reasonable levels.
