Topic Overview

Most people will have some kind of urinary problem or injury in their lifetime. Urinary tract problems and injuries can range from minor to more serious. Sometimes, minor and serious problems can start with the same symptoms. Many urinary problems and injuries are minor, and home treatment is all that is needed to relieve your symptoms.

Urinary symptoms

Common symptoms of a urinary problem include:

• Burning with urination (dysuria). This is the most common symptom of a urinary tract infection.
• Frequent urge to urinate without being able to pass much urine (frequency).
• Pain on one side of the back (flank pain).
• Fever.
• Urgent need to urinate (urgency).
• Feeling like you can't completely empty your bladder.
• Blood in the urine (hematuria). Your urine may look red, brown, or pink. Blood in the urine may occur after intense exercise, such as running or bicycling.
• Leaking urine (incontinence).
• Nausea and vomiting.

When you only have one symptom or if your symptoms are vague, it can be harder to figure out what the problem is. If you are slightly dehydrated, your urine will be more concentrated, and urinating may cause discomfort. Drink more fluids—enough to keep your urine light yellow or clear like water—to help decrease discomfort.

Urinary tract infections

When you have a urinary tract infection (UTI), you may have several urinary symptoms. UTIs are more common in women than in men. This is because the urethra is shorter in women and comes into contact with bacteria from the skin, anus, and vagina. You can reduce your chance of having a UTI by controlling risk factors that can cause these infections.

Infections that commonly cause UTI symptoms include:

• Bladder infections, which are the most common type of UTI, and occur most often in sexually active women ages 20 to 50. An estimated 50% of women develop bladder infections sometime during their lives.
• Kidney infections, which are less common and more serious than bladder infections.
• Prostatitis and epididymitis. These are urinary tract problems in men. For more information, see the topics Prostatitis and Epididymitis.
• Urethritis, which can occur with sexually transmitted infections (STIs), causing pain with urination. For more information, see the topic Exposure to Sexually Transmitted Infections.
• Interstitial cystitis. This causes symptoms like a UTI, but no infection is present.

Other urinary problems

Kidney stones are another urinary problem that can cause mild to severe urinary symptoms. Men ages 20 to 30 are affected most often with kidney stones, but anyone can get stones at any age. For more information, see the topic Kidney Stones.

An injury to the genital area can cause severe pain. Usually the pain subsides over the course of a few minutes to an hour. The severity of the pain is not always an indicator of the severity of the injury. After an injury such as a hit to the genital area, it is important to watch for urinary problems. You usually need to see your doctor if you are having trouble urinating, can't urinate, have blood in your urine, have swelling, or have ongoing pain.

In women and girls, genital skin irritation can cause pain with urination.

Urinary problems related to aging

As people age, some urinary problems become more common. Stress incontinence is the most common form of urinary incontinence in older women. Multiple childbirths, aging, and decreasing hormone levels may cause changes in the pelvic muscles and supportive structures that lead to stress incontinence. It may also occur in men, especially those who have had prostate surgery. For more information, see the topic Urinary Incontinence in Women or Urinary Incontinence in Men.

In men, trouble urinating or the inability to urinate is often caused by prostate enlargement. For more information, see the topic Benign Prostatic Hyperplasia (BPH).
