Urinary Obstruction. Calculi, Cancer, Clots & BPH Flashcards
Urolithiasis and Nephrolithiasis
- Calculi (stones) in the urinary tract or kidney
**30-50-year-olds
**Males > females
-Pathophysiology
-Causes: may be unknown
-Depends on location and presence of obstruction or infection
-Pain and hematuria
-Diagnosis: radiography, blood chemistries, and stone analysis; strain all urine and save stones
Urinary Calculi: Pathophysiology
- r/t increased concentrations of calcium oxalate, calcium phosphate & uric acid = supersaturation
- Factors that increase stone formation depends on stone type
**Decreased calcium metabolism (meaning breaking down of Ca )- anything that slows urine drainage-infection, urinary stasis, immobility
**Hypercalcemia (bloood )& hypercalciuria xk nephrons don’t recycle any on the calcium (urine)
**Uric Acid – assess for gout
**Struvite – alkaline environment, bacteria
Potential Sites of Urinary Calculi?
Renal Calculi: Clinical Manifestations
- Depend on the location
-Renal pelvis-deep backache (costovertebral angle), hematuria
-Ureter=acute, colicky, wavelike, radiates to thigh & genitalia
-Bladder= retention, irritation similar to UTI - Depend on obstruction, infection and edema
-Obstruction
-Infection – pyelonephritis, UTI (fever & chills)
-Edema
Renal Calculi: Assessment
Pain
N, V, D, and abdominal distention
Assess for UTI
Assess for obstruction
POCT for hematuria
Strain urine for stones or gravel
Assess for signs of FVE because if the stone blocks the urine way out it can cause an edema
Renal Calculi: Diagnostics
Non contrast CT (no dye as opposed to regular CT)
Serum chemistry panel
24-hour urine for calcium, uric acid, sodium, pH, volume
Diet and medication history
Family history
Renal calculi: Medical Management
- Manage pain
- Encourage fluids or use IV isotonic fluids (to push stones out)
- Remove the stone and relieve obstruction
-Prevent nephron destruction
-Control infection
4.Analyze the stone
Methods of Treating Renal Stones
slides 10-11-12 but we have already done that in previous decks in Urinary Tract Infections Retention, Reflux & Incontinence
Patient Education for stones (seen in previous decks seen )
Signs and symptoms to report
Follow-up care
Urine pH monitoring
Measures to prevent recurrent stones
Importance of fluid intake
Dietary education
Medication education as needed
Genitourinary Trauma
- Ureteral: motor vehicle accidents, sport injuries, falls
- Bladder: pelvic fracture, multiple trauma, blow to lower abdomen
- Urethral: blunt trauma to lower abdomen and pelvis
—–s/s classic triad: blood visible at the meatus, inability to void, distended bladder
Genitourinary Trauma Management
- Medical management: control hemorrhage, pain and infection; monitor for oliguria, shock, s/s acute peritonitis
- Surgical management: suprapubic catheter, surgical repair
- Nursing management:
-Assess frequently
-Instruction about incision care and adequate fluid intake
-Changes to report: fever, hematuria, flank pain
Conditions of the Prostate: BPH
Benign prostatic hyperplasia (BPH; enlarged prostate)
Affects half of men older than 40 years of age and 50% of men older than 60 years of age
Manifestations are those of urinary obstruction, urinary retention, and urinary tract infections
Develops over a period of time; changes in urinary tract slow and insidious
Symptoms depend on severity: dysuria, hesitancy, sensation of incomplete bladder emptying
Management of BPH
- Medical treatment
-Alpha-adrenergic blockers
-Measures to reduce pain and spasms
-Catheter for acute condition; unable to void - Surgical treatment
-Minimal invasive therapy
-Surgical resection
-TURP
Urinary Tract Cancers
Bladder, kidney and renal pelvis, ureters, other structures such as prostate
Cancer of bladder:
-More common after age 55 years
-Leading cause of death
-Smoking increases risk 50%; refer to Chart 55-13
S/S: visible painless hematuria; pelvic or back pain may indicate metastasis
Diagnosis: ureteroscopy, excretory
urography, CT, MRI, ultrasonography
Bladder Cancer Management don’t confuse with prostste
- Medical management: depends on the grade and stage of the tumor
-Chemotherapy
-Radiation - Surgical management:
-Transurethral resection (cut bad tissue ) or fulguration (use electric shock to eliminate it )
-Followed by bacille Calmette–Guérin (BCG) treatment
-Cystectomy
-Urinary diversion
Nursing Management of Bladder Cancer
Immediate postop: monitor urine volume hourly
Provide stoma and skin care (xk ahora no tienen donde guardar esa orina xk se les quito despues del cancer )
Test urine and care for ostomy
Encourage fluids and relieve anxiety
Patient education about self-care: managing ostomy
Sure, here are some additional nursing management considerations for bladder cancer:
Urine testing: The nurse should obtain urine samples for laboratory testing, including urinalysis and urine culture, to monitor for signs of infection and to ensure that the urine is clear of cancer cells.
Stoma care: For individuals who undergo a cystectomy, a surgical procedure to remove the bladder, an ostomy may be created to allow for urine to drain from the body. The nurse should provide education on ostomy care, including how to change the pouch, clean the skin around the stoma, and manage any skin irritation.
Urinary Diversion
Reasons: bladder cancer or other pelvic malignancies, birth defects, trauma, strictures, neurogenic bladder, chronic infection or intractable cystitis; used as a last resort for incontinence
Cutaneous urinary diversion: ileal conduit, cutaneous ureterostomy, vesicostomy, nephrostomy
Continent urinary diversion: Indiana pouch, Kock pouch, uretherosigmoidostomy
Nursing Diagnosis: Preoperative Urinary Diversion
Anxiety
Imbalanced nutrition
Deficient knowledge
Urinary Diversion. Nursing Diagnosis: Postoperative Bladder Cancer
Risk for impaired skin integrity
Acute pain
Disturbed body image
Potential for sexual dysfunction
Deficient knowledge
Ostomy Care –General Overview
What is an ostomy? Describes a surgical procedure that creates an alternative exit route from internal organs or segments of the urinary tract , diverting flow of body waste (urine, feces) to the external surface of the body
What is a stoma? Refers to the opening where the ureter or bowel can be visualized protruding through the abdominal wall.
What is a diversion? The surgical creation of an alternative route for effluent (waste products) of the urinary or GI tract
-Continent –internal reservoirs
-Incontinent –effluent flows spontaneously
Ostomy Care-Urostomy
Most urinary ostomies involve the bladder and ureters
Types
- Non-Continent (It is a non-continent type of urinary diversion, meaning that the urine drains freely from the body and is collected in an external pouch or bag.)
Ileal conduit – used after bladder removal where the ureters are re-routed and drain freely into part of the ileum that was cut
**Advantages – well established surgery, long term results are well understood
**Disadvantages – requires an external pouching system that needs to be replaced at regular intervals; empty every 3-4 hours; potential for backup of urine into the kidneys (risk for infection)
Ureterostomy
Vesicostomy (bladder )
Cutaneous Urinary Diversions check slide 26
Ostomy Care- Urostomy
Types:
- Continent (made inisde the body after the removal of the bladder using one own’s bowel)–goal is to provide a segment of the intestines to construct a low- pressure pouch to store urine
- Indiana pouch –a continent urinary diversion that is drained by catheterization
- Mitrofanoff continent urinary diversion (a valve is cerated using your own tissue)
- Orthotopic Neobladder – replaces the old bladder with a new one constructed form bowel
-Voiding is accomplished by the -Valsalva maneuver
-Used for those who can maintain their sphincter muscle
-Scheduled voiding
-Pelvic floor exercises
Continent Urinary Diversions slide 28
Urinary stoma
- Indications for stoma
- Conditions: Cystectomy, neurogenic bladder, interstitial cystitis(chronic inflammation), refractory radiation cystitis, bladder incontinence
-Divert urine (urostomy)
-Access
-Protect anastomoses (to prevent disruption or damage to surgical connections made between two structures, such as blood vessels or organs, during a surgical procedure.) - Stoma categories
-End stoma –is formed when the proximal end of the small intestines or colon is used to make the storage pouch for the urinary diversion
-Ureterostomy – involves both ureters being brought through the abdominal wall. There may be two small stomas.
Urostomy Basics
-Urine and mucus pass through the stoma
-There is no sensation in the stoma (no nerve endings)
-The mucus-lined inner surface of the stoma is vascular and can bleed
-Mucus provides a cleansing process
-There is no voluntary control of urine
-Stoma Characteristics:
**Pale pink in color is appropriate for a urinary stoma
**Moist and glossy
**Protrude about 2.5 cm above skin level
**Might appear edematous post op; older stoma may have more texture, grooves and folds
Urostomy Care
Assess stoma and peristomal skin
Assess output
Assess appliance for fit and comfort
Monitor fluid, electrolytes, nutrition
Manage pain
Mobilize
Ostomy Care
-Organizing, Assessing, Changing
**Gather materials for emptying and changing flange/ pouch
**Choose the right time
**Change flange/pouch no more than 3 times/week
**Size the stomal opening
Choosing Products
- Goals:
-Provide patient with an odor-proof secure pouch
-Promote self-care
-Cost effective system - Pouches:
-One piece vs. two piece
-Precut vs cut to fit vs. moldable
-Disposable vs. reusable - Sealants (cremas)
-Provide the skin with an extra protective layer
-Some have alcohol and may burn non intact skin - Barriers
-Used to protect skin from drainage and treat skin loss
-Create more level skin surface for adherence - Clips
-ONE PER BOX OF POUCHES: DO NOT MISPLACE
