Urological Assessment Laboratory examinationRadiographicIVP KUB x-rayKUB ultrasoundCT and MRICystography
Implementation Steps for selected problemsProvide PAIN reliefAssess the level of painAdminister medications usually narcotic ANALGESICS
Implementation Steps for selected problemsMaintain Fluid and Electrolyte BalanceEncourage to consume at least 2 liters of fluid per dayIn cases of ARF, limit fluid as directedWeigh client daily to detect fluid retention
Implementation Steps for selected problemsEnsure Adequate urinary eliminationEncourage to void at least every 2-3 hoursPromote measures to relieve urinary retention:Alternating warm and cold compressBedpan Open faucet Provide privacyCatheterization if indicated
Urinary Tract Infection (UTI)
Bacterial invasion of the kidneys or bladder (CYSTITIS) usually caused by Escherichia coli
Urinary Tract Infection (UTI)
Predisposing factors includePoor hygieneIrritation from bubble bathsUrinary refluxInstrumentationResidual urine, urinary stasisDehydration
Urinary Tract Infection (UTI)
PATHOPHYSIOLOGYThe invading organism ascends the urinary tract, irritating the mucosa and causing characteristic symptomsUreter= ureteritisBladder= cystitisUrethra=UrethritisPelvis= Pyelonephritis
Urinary Tract Infection (UTI)
Assessment findingsLow-grade feverAbdominal painEnuresisPain/burning on urinationUrinary frequencyHematuria
Urinary Tract Infection (UTI)
Assessment findings: Upper UTIFever and CHIILSFlank painCostovertebral angle tenderness
Urinary Tract Infection (UTI)
Laboratory ExaminationUrinalysisUrine Culture
Urinary Tract Infection (UTI)
Nursing interventionsAdminister antibiotics as orderedProvide warm baths and allow client to void in water to alleviate painful voiding.Force fluids. Nurses may give 3 liters of fluid per dayEncourage measures to acidify urine (cranberry juice, acid-ash diet).
Urinary Tract Infection (UTI)
Provide client teaching and discharge planning concerninga. Avoidance of tub baths b. Avoidance of bubble baths that might irritate urethrac. Importance for girls to wipe perineum from front to backd. Increase in foods/fluids that acidify urine.
Urinary Tract Infection (UTI)
Pharmacology1. Sulfa drugsHighly concentrated in the urineEffective against E. coli!Can cause CRYSTALLURIA
2. QuinolonesNot given to less than 18 because they can cause cartilage degradation
3. Pyridium= urinary antisepticCan cause urine discoloration
Nephrolithiasis/UrolithiasisPresence of stones anywhere in the urinary tract Calciumoxalateand uric acid
Nephrolithiasis/Urolithiasis PathophysiologyPredisposing factorsa. Diet: large amounts of calcium and oxalateb. Increased uric acid levelsc. Sedentary life-style, immobilityd. Family history of gout or calculie. Hyperparathyroidism
Nephrolithiasis/Urolithiasis PathophysiologySupersaturation of crystals due to stasis
Stone formation
May pass through the urinary tract
OBSTRUCTION, INFECTION and HYDRONEPHROSIS
Nephrolithiasis/Urolithiasis Assessment findingsAbdominal or flank painRenal colic radiating to the groin3. Hematuria4. Cool, moist skin5. Nausea and vomiting
Nephrolithiasis/Urolithiasis Diagnostic tests 1. KUB Ultrasound and X-ray: pinpoints location, number, and size of stones 2. IVP: identifies site of obstruction and presence of non-radiopaque stones 3. Urinalysis: indicates presence of bacteria, increased protein, increased WBC and RBC (hematuria)
Nephrolithiasis/UrolithiasisMedical management1. Surgerya. Percutaneous nephrostomy: tube is inserted through skin and underlying tissues into renal pelvis to remove calculi.b. Percutaneous nephrostolithotomy: delivers ultrasound waves through a probe placed on the calculus.
Nephrolithiasis/UrolithiasisMedical management2.Extracorporeal shock-wave lithotripsy: delivers shock waves from outside the body to the stone, causing pulverizationPain management : Morphine or MeperidineDiet modification
Nephrolithiasis/UrolithiasisNursing interventions1. Strain all urine through gauze to detect stones and crush all clots.2. Force fluids (30004000 cc/day).3. Encourage ambulation to prevent stasis.

8. Provide client teaching and discharge planning concerning: Adherence to prescribed dietNeed for routine urinalysis (at least every 34 months)Need to recognize and report signs/ symptoms of recurrence (hematuria, flank pain).
Acute renal failure
Sudden interruption of kidney function to regulate fluid and electrolyte balance and remove toxic products from the body
Acute renal failure
Most important manifestation: OLIGURIA
Kidney function
The Nephron produces urine to eliminate wasteImpaired urine production and azotemiaSecretes Erythropoietin to increase RBCANEMIAMetabolism of Vitamin DCalcium and Phosphate imbalancesProduces bicarbonate and secretes acidsMetabolic ACIDOSISExcretes excess POTASSIUMHYPERKALEMIA
Acute renal failurePATHOPHYSIOLOGYPre-renal failure
Intra-renal failure
Post-renal failure
Acute renal failurePATHOPHYSIOLOGYPrerenal CAUSE: Factors interfering with perfusion and resulting in diminished blood flow and glomerular filtrate, ischemia, and oliguria; include CHF, cardiogenic shock, acute vasoconstriction, hemorrhage, burns, septicemia, hypotension, anaphylaxis
Acute renal failurePATHOPHYSIOLOGYIntrarenal CAUSE:Conditions that cause damage to the nephrons; include acute tubular necrosis (ATN), endocarditis, diabetes mellitus, malignant hypertension, acute glomerulonephritis, tumors, blood transfusion reactions, hypercalcemia, nephrotoxins (certain antibiotics, x-ray dyes, pesticides, anesthetics)
Acute renal failurePATHOPHYSIOLOGYPostrenal CAUSE: Mechanical obstruction anywhere from the tubules to the urethra; includes calculi, BPH, tumors, strictures, blood clots, trauma, and anatomic malformation
