Urology

Overview

In the time of the ancient Egyptians and Greeks, doctors frequently examined urine’s color, odor, and texture. They also looked for bubbles, blood, and other signs of disease.Today, an entire field of medicine focuses on the health of the urinary system. It’s called urology. Here’s a look at what urologists do and when you should consider seeing one of these specialists.

 

What is a urologist?

Urologists diagnose and treat diseases of the urinary tract in both men and women. They also diagnose and treat anything involving the reproductive tract in men.In some cases, they may perform surgery. For example, they may remove cancer or open up a blockage in the urinary tract. Urologists work in a variety of settings, including hospitals, private clinics, and urology centers.The urinary tract is the system that creates, stores, and removes urine from the body. Urologists can treat any part of this system. This includes the:

  • kidneys, which are the organs that filter waste out of the blood to produce urine
  • ureters, which are the tubes through which urine flows from the kidneys to the bladder
  • bladder, which is the hollow sac that stores urine
  • urethra, which is the tube through which urine travels from the bladder out of the body
  • adrenal glands, which are the glands located on top of each kidney that release hormones
  • Urologists also treat all parts of the male reproductive system. This system is made up of the:
  • penis, which is the organ that releases urine and carries sperm out of the body
  • prostate, which is the gland underneath the bladder that adds fluid to sperm to produce semen
  • testicles, which are the two oval organs inside the scrotum that make the hormone testosterone and produce sperm

 

What is urology?

  • Urology is the field of medicine that focuses on diseases of the urinary tract and the male reproductive tract. 
  • Which conditions do urologists treat?
  • Urologists treat a wide variety of conditions that affect the urinary system and male reproductive system.

 

In men, urologists treat:

  • cancers of the bladder, kidneys, penis, testicles, and adrenal and prostate glands
  • prostate gland enlargement
  • erectile dysfunction, or trouble getting or keeping an erection
  • infertility
  • interstitial cystitis, also called painful bladder syndrome
  • kidney diseases
  • kidney stones
  • prostatitis, which is inflammation of the prostate gland
  • urinary tract infections (UTIs)
  • varicoceles, or enlarged veins in the scrotum

 

In women, urologists treat:

  • bladder prolapse, or the dropping of the bladder into the vagina
  • cancers of the bladder, kidneys, and adrenal glands
  • interstitial cystitis
  • kidney stones
  • overactive bladder
  • UTIs
  • urinary incontinence

 

In children, urologists treat:

  • bed-wetting
  • blockages and other problems with the urinary tract structure
  • undescended testicles

 

What procedures do urologists perform?

  • When you visit a urologist, they’ll start by doing one or more of these tests to find out what condition you have:
  • Imaging tests, such as a CT scan, MRI scan, or ultrasound, allow them to see inside your urinary tract.
  • They can order a cystogram, which involves taking X-ray images of your bladder.
  • Your urologist can perform a cystoscopy. This involves using a thin scope called a cystoscope to see the inside of your urethra and bladder.
  • They can perform a post-void residual urine test to find out how fast urine leaves your body during urination. It also shows how much urine is left in your bladder after you urinate.
  • They can use a urine sample to check your urine for bacteria that cause infections.
  • They can perform urodynamic testing to measure the pressure and volume inside your bladder.

 

Urologists are also trained to perform different types of surgery. This may include performing:

  • PERCUTANEOUS NEPHROLITHOTOMY (PCNL)/ RETROGRADE INTRARENAL SURGERY (RIRS), endoscopy surgery to remove stones from the kidney
  • URETEROSCOPY(URS), which involves using a scope to remove stones in the kidneys and ureter
  • CYSTOLITHOTRIPSY, endoscopy surgery to remove stones from urinary bladder
  • BIOPSIES of the bladder, kidneys, or prostate
  • TRANSURETHRAL RESECTION OF THE PROSTATE, which involves removing excess tissue from an enlarged prostate
  • PROSTATECTOMY, which involves removing all or part of the prostate gland to treat prostate cancer
  • TRANSURETHRAL RESECTION OF THE BLADDER TUMOUR, which involves removing bladder tumour in its initial stages 
  • CYSTECTOMY, which involves removing the bladder, to treat cancer
  • SLING PROCEDURE, which involves using strips of mesh to support the urethra and keep it closed to treat urinary incontinence
  • VASECTOMY to prevent pregnancy, which involves cutting and tying the vas deferens, or the tube sperm travel through to produce semen
  • LAPAROSCOPIC NEPHRECTOMY, minimal invasive surgery to remove a diseased kidney through small incisions

 

When should you see a urologist?

Your primary care doctor can treat you for mild urinary problems, such as a UTI. Your primary care doctor may refer you to a urologist if your symptoms don’t improve or if you have a condition that needs treatments they can’t provide.

You may need to see both a urologist and another specialist for certain conditions. For example, a man who has prostate cancer can see a cancer specialist called “an oncologist” and a urologist.

 

How do you know when it’s time to see a urologist? Having any of these symptoms suggests you have a problem in the urinary tract:

  • blood in your urine
  • a frequent or urgent need to urinate
  • pain in your lower back, pelvis, or sides
  • pain or burning during urination
  • trouble urinating
  • urine leakage
  • weak urine flow, dribbling

 

You should also see a urologist if you’re a man and you’re experiencing these symptoms:

  • a decreased sexual desire
  • a lump in the testicle
  • trouble getting or keeping an erection
