  1. NURS 2410 Unit 10 and 11GU, Endocrine, Integ Nancy Pares, RN, MSN Metro Community College

  2. Urinary System • Maintains balance of fluid and electrolytes • Removal of waste products • Functionally immature until puberty

  3. Kidneys • Function through filtration, reabsorption, and secretion • Nephrons—the kidney’s functional unit • Filtration occurs at the glomerulus, Bowman’s capsule, and the basement membrane

  4. Kidneys • As child grows, concentration of urine becomes more efficient • Under 2 years old, kidneys less efficient

  5. Ureters • Carry waste fluid from kidneys to bladder

  6. Bladder • Stores urine • Bladder capacity in ounces estimated by adding 2 to child’s age • Muscular organ—contraction of detrusor and relaxation of sphincters result in bladder emptying

  7. Urethra • Excretes urine • Urine excretion occurs around the 12th week of gestation

  8. Clinical Manifestations of Genitourinary Problems • Structural defects and various disorders • May result in reduced or obstructed urine flow • Testing

  9. Structural Defects of Urinary System • Congenital abnormalities involving abnormal location of urethral meatus • Hypospadias—urethral meatus located on ventral surface • Epispadias—urethral opening located on dorsal surface

  10. Figure 31-5 Hypospadias and epispadias. A, In hypospadias, the urethral canal is open on the ventral surface of the penis. B, In epispadias, the urethral canal is open on the dorsal surface.

  11. Structural Defects of Urinary System • Congenital abnormalities involving abnormal location of urethral meatus • Pathophysiology—result from failure of urethral folds to fuse completely over urethral groove

  12. Structural Defects of Urinary System • Congenital abnormalities involving abnormal location of urethral meatus • Nursing management • Preoperative teaching • Fluid intake and output documentation • Education • Catheter and stent care • Incision and penis care

  13. Structural Defects of Urinary System • Congenital abnormalities involving abnormal location of urethral meatus • Postoperative care • Protect surgical site • Pain management • Double diapering

  14. Structural Defects of Urinary System • Obstuctive uropathy and posterior urethral valves • Definition—abnormalities that result in urine backflow into the kidneys • Pathophysiology—caused by several congenital lesions

  15. Figure 31-7 Obstruction may occur in either the upper or lower urinary tract. Common sites of obstruction occur at the ureteropelvic valve, the ureterovesicular junction, or the posterior urethral valve. Why would damage from posterior urethral valves potentially be worse than other obstructions? Renal failure is most likely to occur when both kidneys are affected by hydronephrosis.

  16. Structural Defects of Urinary System • Obstuctive uropathy and posterior urethral valves • Nursing management • Monitor urine output • Pain management • Monitor for infection • Pre- and postoperative care • Diaper placement • Ostomy care

  17. Structural Defects of Urinary System • Vesicoureteral reflux • Definition—retrograde flow of urine from bladder into ureters • Pathophysiology—reflux prevents complete emptying of bladder, reservoir for bacterial growth

  18. Structural Defects of Urinary System • Vesicoureteral reflux • Postoperative care • Monitor urine • IV administration • Family teaching • Monitor for infection • Incision care

  19. Structural Defects of the Reproductive System • Cryptorchidism • Definition—undescended testes • Pathophysiology—occurs when one or both testes fail to descend through inguinal canal into scrotum

  20. Structural Defects of the Reproductive System • Inguinal hernia and hydrocele • Definition—painless inguinal or scrotal swelling • Pathophysiology—peritoneal sac precedes the testicles’ descent into scrotum

  21. Urinary Tract Infection • Definition—viral, bacterial, or fungal infection of the lower or upper urinary tract

  22. Urinary Tract Infection • Pathophysiology—organism enters genitourinary tract and ascends from the urethra to the bladder toward the kidney

  23. Urinary Tract Infection • Assessment • History of UTI • I & O • Physical exam of abdomen and perineal region • Collection of urine

  24. Urinary Tract Infection • Nursing diagnosis • Impaired Urinary Elimination • Urinary Retention • Risk for Deficient Fluid Volume • Nursing management • Medication administration • Hydration status • Assess renal function

  25. Urinary Tract Infection • Teaching • Prevention

  26. Chronic Renal Failure • Slow, irreversible reduction in kidney function over months or years • Caused by congenital defects, cystic and inherited diseases, glomerulonephritis, hereditary disorders, and acquired disorders

  27. Chronic Renal Failure • Delay in growth and development is a common outcome • High-quality protein diet is needed to support growth • Optimal intake is 2.5g/kg/day

  28. Nursing Management • Monitor height and weight • Assess development • Meet nutritional needs • Provide emotional support

  29. LEARNING OUTCOME 5 • Summarize dietary restrictions for the child with a renal disorder.

  30. LEARNING OUTCOME 5 • Children with kidney disease—risk for malnutrition

  31. LEARNING OUTCOME 5 • Chronic renal failure: • Small frequent meals high in protein (2.5g/kg/day) • High calorie intake • Adequate calcium • May require enteral feedings • Complex carbohydrates • Fruits and vegetables low in potassium

  32. LEARNING OUTCOME 5 • Chronic renal failure: • Limit phosphorous, potassium, and sodium • Nephrotic syndrome • Regular protein • Low-sodium diet • Acute glomerulonephritis • Low protein • No-added-salt diet

  33. LEARNING OUTCOME 6 • Describe psychosocial issues for the child requiring surgery on the genitourinary tract.

  34. Genitourinary Surgery—Nonemergent vs. Emergencies • Infancy vs. older child • Parental concerns • Injury, infection, disfigurement, and preservation of renal and reproductive function

  35. Genitourinary Surgery—Nonemergent vs. Emergencies • Parental teaching • Bladder elimination procedures, special dressing and diapering, bathing, hydration assessment, wound care, and infection control • Assess family coping mechanisms and support systems

  36. Genitourinary Surgery—Nonemergent vs. Emergencies • Assess level of understanding of the surgery and concerns • Provide parents with the opportunity to discuss concerns • Psychological counseling may be beneficial

  37. Nursing Management • Reduce postoperative complications • Reduce parental and child stress • Promote positive body image

  38. LEARNING OUTCOME 7 • Develop a nursing care plan for the child with acute and chronic renal failure on peritoneal dialysis.

  39. Types of Dialysis • Hemodialysis • Peritoneal

  40. Nursing Management • Electrolyte monitoring • Intake and output • Vital signs • Heparin administration • Monitor for bleeding and infection • Complications: hypotension, rapid fluid and electrolyte exchange, and disequilibrium syndrome

  41. Sexually Transmitted Infections (STIs) • Pathophysiology: numerous bacterial, parasitic, and viral organisms transmit sexually due to avoidance of protective barriers, multiple sexual partners, frequent sexual activity, failure to seek medical treatment, and sexual abuse

  42. Sexually Transmitted Infections (STIs) • Nursing management • Identify signs and symptoms, assess for asymptomatic STI • Symptoms: 75% are asymptomatic • Symptoms may include endocervical discharge, pelvic pain, vaginal spotting, urethritis, dysuria

  43. Sexually Transmitted Infections (STIs) • Nursing management • Assess for psychosocial impact • Good communication and nonjudgmental approach • Education and prevention
