Ultrasound: Uses sound waves to create images of the kidneys, bladder, and urinary tract, helping detect abnormalities such as stones, tumors, or structural issues. Cystoscopy-A procedure in which a thin tube with a camera (cystoscope) is inserted through the urethra into the bladder. Management Pelvic muscle exercises (also known as Kegel exercises) work the muscles that you use to stop urinating-to strengthen bladder control (helps you hold urine in your bladder longer.) Learn more about pelvic floor exercises and how to do them. Bladder Retraining: In cases of urgency incontinence, bladder retraining can help control the urge to urinate. This involves gradually increasing the time between bathroom visits. Lifestyle changes may help with incontinence. Losing weight,  quitting smoking, saying “no” to alcohol, drinking less caffeine (found in coffee, tea, and many sodas), preventing constipation and avoiding lifting heavy objects may help with incontinence.  Choosing water instead of other drinks and limiting drinks before bedtime may also help Staying hydrated Drinking plenty of fluids can help prevent urinary tract infections and kidney stones. Aim to drink at least 8 glasses of water per day, or more if you're exercising or spending time in hot weather. Dietary Modifications Reduce Irritants: Limit bladder irritants like spicy foods, artificial sweeteners, and acidic foods (e.g., citrus).
