1 Nursing of Adults with Medical & Surgical Conditions Urinary Disorders

2 Diagnostic Tests Urinalysis –Rationale Identifies normal and abnormal constituents in the urine See Table 10-2; Page 414 –Constituent –Normal Range –Influencing factors –Nursing Interventions Clean catch or catheterized specimen Sent to lab immediately

3 Culture and Sensitivity –Rationale Confirm suspected infections Identify causative organisms Determine appropriate antimicrobial therapy –Nursing Interventions Clean catch or catheterized urine specimen

4 Blood Urea Nitrogen –Rationale Determine the kidney’s ability to rid the blood of urea (results from protein breakdown). Normal range: –10-20 mg/dl Urea is excreated entirely by the kidneys and is therefore an indication of kidney function. –Nursing Interventions NPO for 8 hours Elevated BUN may cause disorientation or seizures

5 Blood Creatinine –Rationale Measures the amount of creatinine in the blood Creatinine is excreated entirely by the kidneys and is therefore an indication of kidney function. Normal range: – mg/dl

6 Creatinine Clearance –Rationale Determine the renal excretory function Normal range: –Serum: mg/dl –Urine: ml/min (male) ml/min (female) -Nursing Interventions: -Fasting blood sample is drawn at onset of testing and another at the conclusion -24 hour urine specimen -Discard first specimen -Collect ALL urine in 24 hour period

7 Prostate-Specific Antigen (PSA) –Rationale Glycoprotein produced by normal prostatic tissue Normal Range: –Less than 4 nanoagrams/ml –Nursing Interventions Be sure blood sample is obtained before physical exam. –Manipulation will cause elevated results Elevated levels result from prostate cancer, BPH, and prostatitis

8 Kidney-Ureter-Bladder Radiography (KUB) –Rationale Assesses the general status of the abdomen and evaluates the size, structure, and position of the urinary tract structures –Nursing interventions No special preparation

9 Intravenous Pyelogram (IVP) –Rationale Evaluates structures of the urinary tract, filling of the renal pelvis with urine, and transport of urine to the bladder Radiopaque dye is injected into a vein Radiographs are taken at intervals as dye is excreated by the kidneys –Nursing Interventions Ask patient if allergic to iodine NPO 8 hours Be sure it is scheduled before any barium studies

10 Retrograde Pyelography –Rationale Examination of the lower urinary tract with a cystoscope Radiopaque dye is injected directly into the ureters –Nursing Interventions No special preparation May be NPO if sedation is required

11 Voiding Cystourethrography –Rationale Used to detect abnormalities of the urinary bladder and urethra Dye is injected into an indwelling catheter to outline the lower urinary tract Radiographs are taken – pt. will be asked to void during radiographs –Nursing Interventions Enema before testing

12 Endoscopic Procedures (Cystoscope) –Rationale Visual examination to inspect, treat, or diagnose disorders of the urinary bladder and proximal structures using an instrument with a scope and light source Patient is sedated and local anesthetic is given –Nursing Interventions Preoperative preparation PostProcedure: Encourage fluids, monitor urine for amount, color, dysuria

13 Renal Angiography –Rationale Evaluation of blood supply to the kidneys, evaluated masses, and detects possible complications after renal transplant Radiopaque dye is inserted into an artery –Nursing Interventions NPO 8 hours Post Procedure: –Flat in bed for several hours –Assess puncture site for bleeding or hematoma –Maintain pressure dressing at the site –Assess circulatory status of the extremity q15min for 1hr then q2hrs for 24 hr.

14 Urodynamic Studies (Cytometrogram) –Rationale Indicated when neurological disease is suspected of being an underlying cause of incontinence Catheter is inserted into the bladder and connected to a cystometer, which measures bladder capacity and pressure The patient will be asked about sensations of heat, cold, and urge to void during exam

15 Computed Tomography (CT) Magnetic Resonance Imaging (MRI) Renal Scan Ultraonography Renal Biopsy

77 Dialysis A medical procedure for the removal of certain elements from the blood through a semipermeable membrane (external or pertoneum) Mimics kidney function Two types: –Hemodialysis –Peritoneal dialysis

78 Hemodialysis Requires an access to the patient’s circulatory system to route blood through the artificial kidney (dialyzer) for removal of wastes, fluids, and electrolytes and then return the blood to the patient’s body –Access Temporary –Subclavian or femoral catheters –External shunt in the forearm Permanent –Arteriovenous fistual in the forearm –Frequency Three time a week for 3 to 6 hours

79 Peritoneal Dialysis The peritoneum is used as the semipermeable membrane instead of the dialyzer. A catheter is placed in the peritoneal space A dialyzing fluid is instilled for a predetermined period of time, then drained. Frequency 4 times a day; 7 days a week approximately minutes each time

80 Peritoneal Dialysis

81 Surgical Procedures for Urinary Disorders Nephrectomy –Surgical removal of the kidney –Post-Op Assess for hemorrhage Monitor v/s Maintain urinary drainage system

82 Surgical Procedures for Urinary Disorders Nephrostomy –Incision to drain the pelvis of the kidney –Post-Op –Maintain urinary drainage system –Assess for hemorrhage –Keep dressing clean and dry –Never clamp a nephrostomy tube

83 Surgical Procedures for Urinary Disorders Kidney Transplantation –Nonfunctioning kidney remains in place –Donor kidney is placed in the iliac fossa –Post-Op Assess for s/s of rejection and infection –Apprehension, edema, fever, increased blood pressure, oliguria, tenderness over graft site Immunosuppressive agents –Cyclosporine Corticosteroids Mycophenolate mofetil –New drug helps prevent rejection

84 Surgical Procedures for Urinary Disorders Urinary Diversion –Ileal Conduit Ureters are implanted into a lop of the ileum that is isolated and brought to the surface of the abdominal wall Drainage bag is placed over the stoma to collect the urine –Continent Ileal Urinary Reservoir or Kock’s Pouch Implantation of the ureters into a segment of the small intestine which has been removed Control of urine is achieved by the use of a nipplelike valve that prevents leakage of urine The patient inserts a catheter through the valve at regular intervals to drain the reservoir
