Renal calculi ppt

  1. 1. LEARNING OBJECTIVES• review the anatomy and physiology of the renal system• interpret the term renal calculi• describe the etiology of renal calculi• discuss the pathogenesis involved in the disease process• list the types of renal calculi
  2. 2. LEARNING OBJECTIVES• examine the clinical manifestations closely• differentiate the various diagnostic measures• explain the medical management• Identify the surgical management of renal calculi• distinguish the nursing management for renal calculi including the nursing diagnosis
  3. 3. THE RENAL SYSTEM
  4. 4. THE RENAL SYSTEM
  5. 5. DEFINITION• Nephrolithiasis refers to renal stone disease; urolithiasis refers to the presence of stones in the urinary system. Stones, or calculi, are formed in the urinary tract from the kidney to bladder by the crystallization of substances excreted in the urine•

  10. 10. PATHOPHYSIOLOGY• Slow urine flow, resulting in supersaturation of the urine with the particular element that first become crystallized and later become stone
  11. 11. PATHOPHYSIOLOGY• Damage to the lining of the urinary tract
  12. 12. PATHOPHYSIOLOGY• Decreased inhibitor substances in the urine that would otherwise prevent supersaturation and crystalline aggregation
  13. 13. TYPES OF STONES• Calcium Phosphate• Calcium oxalate• Uric acid• Cystine• Struvite
  14. 14. CLINICAL MANIFESTSTIONS• Severe abdominal or flank pain• Frequency and dysuria• Oliguria and anuria in obstruction
  15. 15. CLINICAL MANIFESTSTIONS• Hematuria• Renal colic• Nausea• hydronephrosis

  25. 25. OTHER TECHNIQUES• Avoiding over hydration and under hydration• Strain the urine• Send any strained stone to laboratory to aid in preventive treatment in the future

  37. 37. NURSING MANAGEMENT
  38. 38. NURSING DIAGNOSIS• Acute pain related to irritation and spasm from stone movement in the urinary tract as manifested by complaints of pain, facial grimacing, restlessness
  39. 39. NURSING DIAGNOSIS• Anxiety related to uncertain outcome and lack of knowledge regarding possible surgery as manifested by expressions
  40. 40. NURSING DIAGNOSIS• Ineffective therapeutic regimen management related to lack of knowledge as manifested by repeated questions
  41. 41. NURSING DIAGNOSIS• Impaired urinary elimination related to trauma or blockage of ureters or urethra as manifested by decreased urinary output and bloody urine
  42. 42. NURSING DIAGNOSIS• Risk for infection related to introduction of bacteria following manipulations of the urinary tract and obstructed urinary blood flow
  43. 43. PREVENTION• Avoid protein intake; usually protein is restricted to 60g/day to decrease urinary excretion of calcium and uric acid.• A sodium intake of 3 to 4 g/day is recommended. Table salt and high-sodium foods should be reduced, because sodium competes with calcium for reabsorption in the kidneys.
  44. 44. PREVENTION• Low-calcium diets are not generally recommended,except for true absorptive hypercalciuria. Evidence shows that limiting calcium, especially in women, can lead to osteoporosis and does not prevent renal stones.• Avoid intake of oxalate-containing foods (eg, spinach,strawberries, rhubarb, tea, peanuts, wheat bran).
  45. 45. PREVENTION• During the day, drink fluids (ideally water) every1 to 2 hours.• Drink two glasses of water at bedtime and an additional glass at each nighttime awakening to prevent urine from becoming too concentrated during the night.
  46. 46. PREVENTION• Avoid activities leading to sudden increases in environmental temperatures that may cause excessive sweating and dehydration.• Contact your primary health care provider at the first sign of a urinary tract infection
