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

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

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
