Urinary System Test Review

Medical Terminology

parts of the kidney
Parts of the Kidney

medulla

  • Cortex

hilum

-outer protective portion

  • Medulla

-inner soft portion

  • Hilum

-a depression located in the middle of the concave side of the kidney where blood vessels, nerves, and the ureters enter and exit the kidneys

cortex

Structure and Function

kidney

Parts of the kidneys

structure and function
Structure and Function
  • The ureter (ureter/o), carries urine (urin/o) from the kidney (ren/o, nephro/o) to the urinary bladder (cyst/o).
  • A person feels the urge to urinate (-uria) when the bladder has 1 cup of urine (urin/o)
flow of urine
Flow of Urine

glomerulus

renal tubules

renal pelvis

renal calices

Structure and Function

Flow of Urine

Nephron

Renal artery

Renal vein

Ureter

Renal medulla

Renal capsule

Renal cortex

Filtered blood exits the kidneys via the renal vein.

The renal tubules carry urine to ducts in the renal cortex.

ureters

structure and function1
Structure and Function

Blood Flow

Glomeruli

Urine Flow

Structure and Function

  • Blood flows through the glomerulus at a constant rate.
  • Each glomerulus is surrounded by a capsule known as Bowman’s capsule.
  • Blood then passes into the renal tubules where some substances are reabsorbed and the remaining become urine.
structure and function2
Structure and Function
  • There are more than 1 million nephrons in each kidney (nephr/o, ren/o).

Urine is produced by filtration of:

  • creatine
  • uric acid
  • sugar
  • urea
  • water
  • salts
terms and meanings
Terms and Meanings
  • Anuria:An without

  • Anuria means without urine
  • Dysuria: Dys difficult/painful

-uria urine/urination

blood tests
Blood Tests

Diagnostic, Procedural and

Laboratory Terms

Blood Tests

  • Blood Urea Nitrogen (BUN)
  • Creatinine Clearance Test

The presence of high amounts of urea or creatinine in the blood shows that the kidney is not properly filtering these substances.

imaging tests
Imaging Tests

Diagnostic, Procedural and

Laboratory Terms

Imaging Tests

  • Cystoscopy

-tubular instrument used to examine the bladder

  • Intravenous Pyelogram

-x-rays of the urinary tract after a contrast medium is injected into the bloodstream

  • KUB

-x-ray of three parts of the urinary tract (kidney, ureter, and bladder)

  • Renal Scan

-radioactive imaging used to diagnose kidney disorders

urinary tract procedures
Urinary Tract Procedures

Diagnostic, Procedural and

Laboratory Terms

Dialysis solution

Urinary Tract Procedures

Dialysis

  • Hemodialysis
  • -the process of filtering blood outside the body in an artificial kidney machine that returns the blood back to the body after filtering.
  • Peritoneal dialysis (pictured)
  • -the insertion and removal of a dialysis solution into the peritoneal cavity.

Pathological Terms

Terms Used to Describe Difficulties in Urination

anuresis

polyuria

  • Excessive urination
  • No urinary output

incontinence

dysuria

  • Involuntary discharge of urine or feces
  • Painful urination

enuresis

oliguria

  • Lack of bladder control
  • Scanty urination
surgical terms
Surgical Terms

Surgical Terms

Parts of the urinary system may be surgically removed

  • Nephrectomy- removal of a kidney
  • Ureterectomy- removal of a ureter
  • Cystectomy- removal of the bladder

Surgical repair procedures

  • Pyeloplasty- repair of the renal pelvis
  • Cystoplasty- repair of the bladder
  • Urethroplasty- repair of the urethra

A urostomy is the creation of an artificial opening in the abdomen through which urine exits the body.
