Copyright © 2006 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 3 Anatomy and Physiology Kidneys, ureters, bladder, and urethra Kidneys are responsible for removing waste products from the bloodstream

Copyright © 2006 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 4 Anatomy and Physiology Ureters are tubules that run from kidney to bladder transporting urine Bladder is a muscular organ that holds urine Urethra carries urine to outside of body

Copyright © 2006 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 5 Anatomy and Physiology Urine is normally –Clear –Slightly yellow to gold –Free from sediments –Distinct odor but not foul smelling

Copyright © 2006 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 6 Anatomy and Physiology Urine is normally –Specific Gravity is to –pH is 6 –Changes in these values indicate disease

Copyright © 2006 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 7 Common Signs and Symptoms Urinary Disease –Hematuria –Pyuria –Proteinuria –Dysuria

S’s & Sx’s urinary frequency, urgency maybe incontinence urine may be dark yellow with foul odor may have pain in pelvic area, lower back bladder spasms fever, chills

ALL RIGHTS RESERVED. 11 Common Diseases of the Urinary Tract Urinary Tract Infections (UTIs) –Broad diagnosis covering infections of urinary tract including the urethra, bladder, and kidneys –Caused by virus and fungi but most often are bacterial –Most common bacteria is escherichia coli (E.coli)

Copyright © 2006 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 12 Common Diseases of the Urinary Tract Affects females more frequently than males –Female urethra is shorter –Female urethral opening is closer to rectum –Improper female toilet habits

Copyright © 2006 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 13 Common Diseases of the Urinary Tract Affects females more frequently than males –Vaginal secretions may harbor bacteria –Sexual intercourse may cause trauma to urethra and bladder leading to inflammation and infection

Copyright © 2006 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 14 Common Diseases of the Urinary Tract Affects females more frequently than males –Pregnant females are more susceptible to infection due to pressure of uterus on urinary tract –Male prostatic secretions have antibacterial effect, reducing risk of UTI

Etiology - can be secondary to STD’s Diagnosis – –Is made by U/A clean catch urine → shows abnormal color, odor, RBCs, WBCs Urine culture & sensitivity Cystoscopy Treatment: –specific antibiotics, urinary analgesics –organism specific antibiotics, urinary analgesics

Patient Teaching ↑ water intake for females, proper wiping technique of perineum → front to back avoid sexual intercourse during UTI episodes Citrus juice like cranberry concentrate or lemon

Some specific UTI’s Urethritis –More common males due to STD (gonorrhea) –Females due to soap, lotion sex, STD –Inflammation of the urethra –Symptoms include swelling of the urethra, dysuria, and urethral discharge

Cystitis ~ bladder infection –Again diagnosis is a urinalysis –Most common UTU –Medication turns urine a DARK red –Treatment is antobiotics

same Pyelitis –Pelvis of the kidney inflammation –Ascending infection –Young female chhildren Pyelonephritis –Ascending infection –Obstruction of the urine –Tumor needs to be ruled out

Acute Glomerulonephritis: Inflammation of glomerulus or filtering unit of kidney Is usually caused by a delayed immune response to a streptococcal infection May lead to renal failure

Glomerulus Similar to rheumatic heart disease – autoimmune response causes end-organ damage (causes antigens to be released that attack the Glm., the whole complex can be stuck)

ALL RIGHTS RESERVED. 26 Glomerulonephritis Glomerulonephritis (chronic) –Repeated bouts lead to chronic condition –Symptoms include those of acute glomerulonephritis and hypertension –Uremia may occur during late stages –Treatment includes peritoneal or hemodialysis

Renal Failure: Failure of kidneys to cleanse waste from the blood Acute Renal Failure – an abrupt reduction in kidney function that is usually reversible. Chronic Renal Failure – slow, progressive loss of nephrons caused by a variety of underlying diseases.

Renal Failure Acute and chronic failure is diagnosed with: –Blood urea nitrogen, creatinine –Uremia –Ammonia

Acute Symptoms are not significant until 75 percent of kidney function is destroyed Decreased blood flow to kidneys Shock is a big cause, as are medications –Like Tylenol© Embolism, heart failure and dehydration also can cause it

Chronic Renal Failure: Presents as a slow, progressive condition resulting from the gradual loss of nephrons. Caused by many disease processes including infection, glomerulonephritis, tumors, auto-immune disorders, and obstruction of the urinary tract.

Renal failure Usually no sx until failure is 75% Chronic is much slower, Sx don’t show up until much further degeneration of the parenchyma has occurred. Sx include: –Oliguria, hematuria, albuminumemia, proteinuria

Stages of Chronic Renal Failure: 1. Stage One – some nephrons are lost but the remaining nephrons compensate and maintain urine output. 2. Stage Two – renal insufficiency. The progressive loss of nephrons becomes critical and the remaining nephrons can no longer compensate.

Stages of Chronic Renal Failure – Continued: 3.Stage Three – End Stage Renal Disease (ESRD) Urine is no longer being formed Urine is no longer being formed Toxins, waste, and fluid build up in the body. Toxins, waste, and fluid build up in the body. Renal Dialysis or kidney transplant becomes necessary – otherwise death occurs. Renal Dialysis or kidney transplant becomes necessary – otherwise death occurs.

Chapter 14 Endocrine System Diseases and Disorders

Obiectives At the end of this lesson the student will: Be able to identify the anatomy and physiology of the endocrine system Identify the common signs and symptoms of endocrine disorders Describe the signs and symptoms, causes, treatments and prognosis of selected diseases in this systems

Thyroid disorders Releases T3, T4 and calcitonin in response to TSH from the anterior pituitary Thyroxine and triiodothyronine regulate metabolism Calcitonin regulates calcium and works in opposition to PTH

Copyright © 2006 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 39 Anatomy and Physiology Consists of many glands –Hypothalamus –Pituitary –Pineal –Thymus –Thyroid

Copyright © 2006 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 40 Anatomy and Physiology Consists of many glands –Parathyroids –Adrenals –Pancreatic islets –Ovaries and testes

Copyright © 2006 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 41 Anatomy and Physiology Each gland is unique and delivers its secretion into the bloodstream Negative feedback system controls amount of hormones secreted

Copyright © 2006 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 42 Diagnostic Tests Endocrine glands that can be physically examined are the thyroid and testes Tests: blood and urine testing for hormones CT and MRI check for tumors or alteration in organ size

Copyright © 2006 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 43 Pituitary Gland Diseases Hyperpituitarism –Increase in activity of pituitary gland –Oversecretion especially affects growth hormone leading to excessive growth of bones and tissues

Copyright © 2006 by Thomson Delmar Learning. ALL RIGHTS RESERVED. 44 Pituitary Gland Diseases Hyperpituitarism –If occurs before puberty, giantism occurs –If occurs in adult, acromegaly occurs Affects small bones of hands, feet, and face by enlarging them
