SESSION CONTENTS

STEP 1: Presentation of Session Title and Learning Tasks (5 minutes)

READ or ASK students to read the learning tasks and clarify

ASK students if they have any questions before continuing

STEP 2: Definition and Types of Common Disorders of the Urinary System

(10 minutes)

|Activity: Buzzing (5 minutes) |

| |

|ASK students to pair up and buzz on the following question for 2 |

|minutes |

| |

|What is the disorder of the urinary system? |

|What are the types of the urinary system? |

| |

|ALLOW few pairs to respond and let other pairs to add on points not |

|mentioned |

| |

|WRITE their response on the flip chart/board |

| |

|CLARIFY and SUMMARIZE by using the content below |

Urinary system disorder:

A urinary tract infection (UTI) is an infection in any part of your urinary

system your kidneys, ureters, bladder and urethra.

Most infections involve the lower urinary tract — the bladder and the

urethra.

The common disorders of the urinary tract disorders are:

o Urinary Incontinence and retention

o Urinary tract infections

o Inflammatory disorders

o Obstructive disorders

o Tumours

o Renal failure

o Chronic renal failure

Step 3: Common disorders of the urinary system (25 minutes)

|Activity: Small Group Discussion ( 30 minutes) |

| |

|DIVIDE students into small manageable groups |

| |

|ASK students to discuss on the following question |

|Explain the common disorders of the urinary system? |

| |

|ALLOW students to discuss for 15 minutes |

| |

|ALLOW few groups to present and the rest to add points not mentioned |

| |

|CLARIFY and SUMMARIZE by using the contents below |

• Urinary Incontinence and retention

o Incontinence is due to loss of voluntary control of bladder

o Retention (residual urine) may be due to anatomical defects and is

usually corrected by catheterization

• Urinary tract infections

o These includes Urethritis, Cystitis and Pyelonephritis

o The common causes are:

▪ Ascending infection – women > men
▪ Prostatic hypertrophy with urinary retention
▪ Incomplete emptying of bladder with urinary stasis
▪ Pregnancy associated with stasis Blood borne pathogens
• Inflammatory disorders

o Glomerulonephritis

• Mainly is due to proteinuria, edema, oliguria and autoimmune diseases

o Nephrotic syndrome

• One loses the capacity to retain protein, especially albumin
• May be due to toxic agents like mercury, toxic drugs like aminoglycosides

and diseases like diabetes

o Obstructive disorders

o Kidney stones (Renal calculi)

• Accumulation of calcium, uric acid, urine crystals
• Mostly due to prolonged dehydration and infections
• Is presented by fever, chills, renal colic

o Tumours

• Formation of masses
• Is presented by haematuria

o Renal failure

o Acute renal failure

• Abrupt decrease in renal function
• Usually reversible
• May be caused by Glomerular disease, Severe pyelonephritis and Ischemia

o Chronic renal failure

• Get slow progressive loss of neurons
• Usually irreversible
• May be due to toxins, glomerular disease, hypertension

STEP4: Key Points (5 minutes)

• The common urinary tract disorders include urinary

incontinence/retention, infections, inflammatory disorders, obstructive

disorders and renal failure

• Urinary tract infections are most prominent among other disorders of the

urinary system

• It is important to treat urinary tract infections as early as possible to

avoid the possibilities of kidney stones.

STEP 5: Evaluation (5 minutes)

• What is the disorder of the urinary system?
• What are the common disorders of the urinary system?
• What are the causes of the common disorders of the urinary system?

Step 6: Assignment (10 minutes)

|Activity: Take Home Assignment (10 minutes) |

| |

|DIVIDE learners in groups or individual. |

| |

|ASK the learners to work on the following assignment |

| |

|Explain common disorders of the urinary tract system |

| |

|ALLOCATE time for learners to do the assignment and submit |

| |

|REFER learners to recommended references |
