Urology
Urology is the medical and surgical specialty focused on the urinary tract, bladder, kidneys, ureters, urethra, prostate, male reproductive organs, stones, infections, continence, sexual health, cancer, and reconstructive care.
What urology is
Urology is a medical and surgical specialty focused on the urinary tract and parts of the reproductive system. Urologists care for the kidneys, ureters, bladder, urethra, adrenal glands in some contexts, prostate, testes, penis, and related pelvic structures. The field includes office-based diagnosis, long-term medical management, endoscopic procedures, reconstructive work, cancer care, and emergency surgery.
The urinary tract
The urinary tract moves waste fluid from the blood to the outside of the body. Kidneys make urine, ureters carry it to the bladder, the bladder stores it, and the urethra drains it. This system depends on muscles, nerves, valves, pressure, infection defense, and coordinated emptying. Urology often asks whether urine is being made, stored, moved, and released safely.
Where urology meets nephrology
Urology and nephrology both involve kidneys, but they usually ask different questions. Nephrology focuses on kidney filtering, blood chemistry, blood pressure, and kidney failure. Urology focuses more on urine flow, obstruction, stones, tumors, anatomic problems, the bladder, prostate, urethra, and operations on the urinary tract. Many patients need both perspectives.
Symptoms and first clues
Urologic problems can appear as pain with urination, blood in urine, flank pain, pelvic pain, urinary urgency, weak stream, leakage, frequent nighttime urination, fever with urinary symptoms, infertility, erectile dysfunction, testicular pain, or a finding on imaging. Clinicians look for timing, infection risk, stone history, medications, pregnancy status, cancer risk, neurologic disease, and whether urine flow is blocked.
Tests and procedures
A urinalysis can show blood, protein, infection clues, crystals, or other abnormalities. Urine culture can identify bacteria. Imaging can show stones, tumors, obstruction, kidney swelling, trauma, or anatomic differences. Cystoscopy uses a small camera to inspect the urethra and bladder. Urodynamic testing measures storage and emptying. Procedures may remove stones, open blockages, sample tissue, drain urine, repair anatomy, or treat tumors.
Conditions it covers
Urology covers urinary tract infections, kidney and ureter stones, benign prostatic hyperplasia, urinary incontinence, overactive bladder, urethral strictures, bladder pain syndrome, male infertility, erectile dysfunction, testicular conditions, congenital urinary tract differences, pelvic floor problems, trauma, and cancers of the prostate, bladder, kidney, testis, penis, ureter, or urethra. Pediatric urology handles many conditions that begin before birth or in childhood.
Treatment and prevention
Treatment may include fluids, behavior changes, pelvic floor therapy, antibiotics, medicines for bladder or prostate symptoms, stone prevention plans, catheter care, injections, endoscopic procedures, robotic or open surgery, radiation coordination, or cancer surveillance. Prevention can include UTI risk reduction, stone-risk evaluation, smoking cessation for bladder cancer risk, safer catheter practices, and follow-up for conditions likely to recur.
Why it matters
Urinary and reproductive problems can affect sleep, work, kidney safety, fertility, sexuality, infection risk, dignity, and daily confidence. Some urologic emergencies, such as blocked infected urine flow or testicular torsion, need fast treatment. Good urology care can relieve symptoms, protect kidney function, detect cancer earlier, and help people manage private health concerns without delay or shame.
