Management of Patients with Urinary Disorders


Lower urinary tract infections

Lower Urinary Tract Infections

  • Cystitis (inflammation of the urinary bladder),

  • Prostatitis (inflammation of the prostate gland), and

  • Urethritis (inflammation of the urethra).

  • Upper UTI; Pylonephritis (inflammation of the renal pelvis), interstitial nephritis (inflammation of the kidney), and renal abscesses


Lower urinary tract infections1

Lower Urinary Tract Infections

  • mechanisms maintain the sterility of the bladder:

    • the physical barrier of the urethra,

    • urine flow,

    • ureterovesical junction competence,

    • various antibacterial enzymes and antibodies, and antiadherent effects mediated by the mucosal cells of the bladder.


Risk factors for uti

Risk Factors for UTI

  • Inability or failure to empty the bladder completely

  • Obstructed urinary flow

  • Decreased natural host defenses or immunosuppression

  • Instrumentation of the urinary tract (eg, catheterization, cystoscopic procedures)

  • Inflammation or abrasion of the urethral mucosa

    • Contributing conditions: DM, Pregnancy, neurogenic disorders, Gout, and altered states caused by incomplete emptying of the bladder and urinary stasis


Pathophysiology

Pathophysiology

  • Bacteria gain access to the bladder, attach to and colonize the epithelium of the urinary tract to avoid being washed out with voiding, evade host defense mechanisms, and initiate inflammation.

  • Many UTIs result from fecal organisms that ascend from the perineum to the urethra and the bladder and then adhere to the mucosal surfaces.

  • Escherichia coli is the most common agent


Management of patients with urinary disorders

  • Urethrovesical reflux: With coughing and straining, bladder pressure rises, which may force urine from the bladder into the urethra. (A) When bladder pressure returns to normal, the urine flows back to the bladder (B), which introduces bacteria from the urethra to the bladder. Ureterovesical reflux: With failure of the ureterovesical valve, urine moves up the ureters during voiding (C) and flows into the bladder when voiding stops (D). This prevents complete emptying of the bladder. It also leads to urinary stasis and contamination of the ureters with bacteria-laden urine.


Routes of infection

Routes of Infection

  • transurethral route (ascending infection),

  • through the bloodstream (hematogenous spread), or

  • by means of a fistula from the intestine (direct extension)


Clinical manifestations

Clinical Manifestations

  • About half of all patients with bacteriuria have no symptoms.

  • dysuria (painful or difficult urination), burning on urination, frequency (voiding more than every 3 hours), urgency, nocturia, incontinence, and suprapubic or pelvic pain. Hematuria and back pain may also be present


Gerontologic considerations

Gerontologic Considerations

  • High incidence of chronic illness

  • Frequent use of antimicrobial agents

  • Presence of infected pressure ulcers

  • Immunocompromise

  • Cognitive impairment

  • Immobility and incomplete emptying of bladder

  • Use of a bedpan rather than a commode or toilet


Diagnosis

Diagnosis

  • UA: puss cells > 4, ? hematouria

  • C&S.

  • WBCs


Medical management

Medical Management

  • Pharmacological agents according to C&S

  • Patient should be instructed to complete the antibiotic course

Acute pyelonephritis

Acute Pyelonephritis

  • Clinical Manifestations

    • Chills, fever, leukocytosis, bacteriuria and pyuria.

    • Low back pain, flank pain, nausea and vomiting, headache, malaise, and painful urination are common findings.

    • Pain and tenderness in the area of the costovertebral angle

    • Symptoms of lower UTI


Medical managmenet

Medical managmenet

  • On out patient basis: AB for 2 weeks

  • Good oral hydration

  • If there is a relapse, AB for 6 weeks

  • If there is N&V > admission, IV Fluids and IV AB


Chronic pyelonephritis

Chronic Pyelonephritis

  • Clinical Manifestations

  • Usually asymptomatic unless an acute exacerbation occurs.

  • Noticeable S&S may include fatigue, headache, poor appetite, polyuria, excessive thirst, and weight loss.

  • Persistent and recurring infection may produce progressive scarring of the kidney resulting in renal failure


Urinary incontinence

Urinary Incontinence

  • Involuntary urination

  • Causes of Transient Incontinence: DIAPPERS

Suprapubic catheters

Suprapubic Catheters

  • Is a temporary measure to divert the flow of urine from the urethra when the urethral route is impassable

  • Inserting a catheter into the bladder through a suprapubic incision or puncture.


Hydronephrosis hydroureter and urethral stricture

Hydronephrosis, Hydroureter, and Urethral Stricture

  • Outflow obstruction

    • Urethral stricture

      • Causes bladder distention and progresses to the ureters and the kidneys

    • Hydronephrosis –

      • Kidney enlarges as urine collects in the pelvis and kidney tissue due to obstruction in the outflow tract

      • Over a few hours this enlargement can damage the blood vessels and the tubules

    • Hydroureter

      • Effects are similar, but occurs lower in the ureter


Causes of obstruction

Causes of Obstruction

  • Tumor

  • Stones

  • Congenital structural defects
