Slide 35
Renal Calculi
Urinary tract obstruction
Pathophysiology
Precipitations of calcium salts (calcium phosphate or calcium oxalate), uric acid,
magnesium ammonium phosphate, or cystine
All are normally found in the urine
Factors for development of calculi
Slide 36
Renal Calculi (cont.)
Signs and symptoms
Pain
Dull flank pain: a calculus in the renal pelvis or stretching of the renal capsule
from urine retention (hydronephrosis)
If calculus lodges in a ureter, excruciating pain in the abdomen that radiates to the
groin or the perineum
TALKING POINTS:
Where do most calculi originate?
Some substances tend to precipitate in acid urine, causing calculus formation; others
precipitate in alkaline urine.
Slide 37
Renal Calculi (cont.)
Medical treatment
Most calculi are passed spontaneously
Ambulation and adequate hydration facilitate passage
Opioid analgesics/antispasmodics relieve pain
Lithotripsy

Slide 41
Urologic Trauma
Penetrating injuries most often from knives or guns
Blunt trauma: a force is applied to the abdominal wall and the energy is diffused into the
abdominal cavity
TALKING POINTS:
What is the most common indication of urologic trauma?
If the injury is not severe, if there is little bleeding, and if there are no signs of shock,
monitor the patient closely.
More severe injuries most likely require surgery to repair damage.

Acute Renal Injury
Causes
Prerenal failure: decreased blood flow to glomeruli
Intrarenal failure: nephrotoxic agents, kidney infections, occlusion of intrarenal
arteries, hypertension, diabetes mellitus, or direct trauma to the kidney
Postrenal failure: obstructions beyond the kidneys that cause urine to back up
TALKING POINTS:
Slide 55
Acute Renal Failure: Stages
Onset stage
Short (1 to 3 days); increasing BUN and serum creatinine with normal to decreased
urine output
Oliguric stage
The urine output decreases to 400 mL/day or less
TALKING POINTS:
What is the urine specific gravity in the oliguric stage?
The patient becomes hypervolemic, meaning that the blood volume is greater than
normal.
Urine osmolality decreases and serum osmolality increases as waste products are
retained.
Acute Renal Failure: Stages (cont.)
Diuretic stage
Urine output exceeds 400 mL/day; may rise above 4 L/day
TALKING POINTS:
Despite the production of large quantities of urine, few waste products are excreted, and
wastes accumulate in the blood during the diuretic stage.
What happens if complete recovery does not occur in the recovery stage?

26 Chapter 42Urologic Disorders _______________________________________________________________
Introduction to Medical-Surgical Nursing, 6th ed.
LESSON 42.2
Slide 62
Chronic Kidney Disease: Signs and Symptoms (cont.)
Neurologic system (mental status changes)
Integumentary system (uremic frost, accumulation of waste products)
GI system (irritation, nausea, vomiting, a metallic taste in the mouth, and bleeding)
Slide 63
Chronic Kidney Disease: Medical Treatment
IV glucose and insulin, calcium carbonate, calcium acetate, or sodium polystyrene
sulfonate to treat hyperkalemia
Statins to decrease risk of cardiovascular complications
Calcium, active vitamin D, and phosphate binders to treat hypocalcemia
TALKING POINTS:
What is the goal of treatment for chronic kidney disease?
When kidney failure can no longer be managed conservatively, dialysis is required to
sustain life.
Slide 64
Chronic Kidney Disease: Dialysis
Passage of molecules through semipermeable membrane into special solution called
dialysate solution
Dialysis operates like the kidney
Small molecules (urea, creatinine, and electrolytes) pass out of the blood, across a
membrane, and into a solution
The goals of dialysis
Remove end products of protein metabolism from the blood
Maintain safe concentrations of serum electrolytes
Correct acidosis and replenish the body’s bicarbonate buffer system
Remove excess fluid from the blood
______________________________________________________________ Chapter 42Urologic Disorders 27
Introduction to Medical-Surgical Nursing, 6th ed.
LESSON 42.2
Slide 65
Chronic Kidney Disease: Dialysis (cont.)
Hemodialysis
Blood is removed and circulated through an “artificial kidney” to remove excess fluid,
electrolytes, wastes
Dialyzed blood then returned to the patient
TALKING POINTS:
What are the advantages of hemodialysis? Disadvantages?
Slide 66
Chronic Kidney Disease: Dialysis (cont.)
Peritoneal dialysis
Uses the patient’s own peritoneum as a semipermeable dialyzing membrane
Fluid instilled into peritoneal cavity
Waste products drawn into the fluid, which is then drained from the peritoneal cavity
May be temporary or permanent
Temporary: catheter inserted into the peritoneal cavity through the abdominal wall
Long-term: catheter is implanted into the peritoneal cavity
Slide 67
Chronic Kidney Disease: Dialysis (cont.)
Peritoneal dialysis
Advantages over hemodialysis: less anemia, reduced cost, fewer dietary and fluid
restrictions, independence, closer to normal kidney function
Disadvantages: risk of peritonitis (the major complication) and catheter site infection,
hyperglycemia, elevated serum lipids, and body image disturbance
Three phases: inflow, dwell, and drain
TALKING POINTS:
What is continuous ambulatory peritoneal dialysis (CAPD)?
Automated peritoneal dialysis uses a device called a cycler to perform the exchanges
during the night.
Peritonitis, infection of the peritoneum, is the most serious complication of peritoneal
dialysis.

TALKING POINTS:
Do not overlook mental and emotional status when assessing the patient with kidney
disease.
What may cause increasing confusion or loss of consciousness?
The long-term effects of chronic kidney disease and its treatment put the patient at risk for
many complications.
Chronic Kidney Disease
Nutrition considerations
Fluid intake may be restricted to 1000 to 1500 mL/day
Slide 70
Chronic Kidney Disease (cont.)
Interventions

Renal Transplantation
Kidney donation
Healthy kidney from live donor (a relative) or cadaver
Tissues must match or recipient will reject new kidney
Matching based on ABO blood groups and human leukocyte antigens
TALKING POINTS:
When a kidney is obtained from a living related donor, the 1-year recipient survival rate is
97.6%.
A national network maintains lists of people awaiting donor kidneys.
When a cadaver kidney is available, the network tries to locate the best match for the
kidney to improve the chances of success.
What disorders may make a person ineligible to be a kidney donor?

Slide 72
Renal Transplantation (cont.)
Preoperative nursing care
Patient must be prepared mentally and physically
Recipient and live donor have complete diagnostic workups to rule out other medical
TALKING POINTS:
The gift of a kidney can restore health, but the recipient may feel guilty about asking a
loved one to endure surgery and to give up an organ.
