Overview
Urology is a branch of medicine that deals with the urinary system, which includes the kidneys, ureters, bladder, and urethra. It also covers the male reproductive organs, including the prostate, penis, and testicles. Urologists care for a wide range of conditions, from urinary tract infections and kidney stones to enlarged prostate, incontinence, infertility, and cancers of the urinary tract or male reproductive system.
Key Symptoms
Symptoms that may lead to urology care include pain or burning with urination, needing to urinate often, leakage of urine, difficulty starting or stopping urine, and waking often at night to urinate. Blood in the urine, flank or lower abdominal pain, swelling of the scrotum, erectile problems, or concerns about fertility can also be reasons for evaluation. Some people are referred to a urologist after abnormal test results even if they have few symptoms.
Causes and Risk Factors
Urologic conditions can be caused by infections, stones, blockages, injury, nerve problems, birth differences, hormonal factors, aging, or cancer. Risk can be affected by dehydration, tobacco use, certain medicines, family history, diabetes, obesity, and repeated urinary infections. Some conditions are linked to pregnancy, menopause, or prostate enlargement with age.
Who Is Affected
Urologic problems can affect infants, children, adults, and older adults. People of any sex can have urinary tract conditions, while some problems such as prostate disease affect only those with a prostate. Older adults are more likely to have issues such as incontinence, prostate enlargement, and some cancers, but younger people can also develop stones, infections, or congenital conditions.
Prevention
Prevention depends on the condition, but helpful general steps include staying hydrated, not smoking, managing diabetes and blood pressure, and seeking treatment for urinary symptoms early. Good toilet and genital hygiene may help lower the chance of some infections. Following workplace or sports safety measures can also reduce injuries to the kidneys or genitals.
Diagnosis and Tests
Diagnosis often starts with a medical history, symptom review, and physical exam. Tests may include urine testing, blood tests, ultrasound, CT scan, MRI, or studies that check how the bladder stores and releases urine. Some people may need cystoscopy, a procedure that lets the doctor look inside the urethra and bladder with a small camera.
Treatment Categories
Treatment depends on the specific problem and may include monitoring, lifestyle changes, pelvic floor therapy, procedures, or surgery. Medicines are commonly used for infections, bladder symptoms, prostate problems, or pain, but the type of treatment must be chosen by a qualified clinician. Cancer care may involve surgery and other specialist treatments coordinated across teams.
When to Seek Medical Care
Arrange medical care if you have repeated urinary infections, trouble urinating, urine leakage, ongoing pelvic or flank pain, a new lump in the scrotum, or sexual or fertility concerns. Blood in the urine, even if it happens only once, should be medically assessed. Early evaluation can help identify infections, stones, obstruction, or other underlying causes.
When It May Be an Emergency
Get urgent medical help if you cannot pass urine, have severe side or back pain, fever with urinary symptoms, heavy bleeding in the urine, sudden testicular pain, or injury to the genitals or lower back. These symptoms can be linked to blocked urine flow, severe infection, torsion of the testicle, or significant bleeding. Emergency care is also important for symptoms of sepsis such as confusion, extreme weakness, or difficulty breathing.
