Retention of urine Retention of urine Presentation Transcript

  • RETENTION OF URINE DR AHMED REHMAN FCPS (URO) Assistant Professor of Urology
  • Causes of Frequency – Dysuria
    • Acute Cystitis and urethritis
    • VUR, and vesical diverticulum neurogenic bladder / decompensation of bladder Cystocele / UV prolapse vesical calculus, foreign body neoplasm of blader, urethra, prostate and penis
    • bladder neck stenosis, Post urethral,valve Urethral stricture Enlarged prostate--------- benign / malignant / inflammatory Urethral Stone / foreign body impaction Ext, meatal stenoaia Phemosis / fused synichae,
    • Detrusor sphincter dyssynergia frequency – dysuria syndrome
    • Atrophic urethritis (senile)
    • Distal urethral syndrome
    • Abacterial cystitis /urethritis ( mycoplasma, herpes, chemical)
    • TB, schistosomiasis
    • Intersitial cystitis
    • Cystitis cystca and Alkaline encrustin cystitis
    • Pregnancy, diabetes, LVF, CCF, diuretics, polyuria
  • Physiology of bladder
    • Low pressure reservoir (compliance / distensibility) 400-550 cc at around 5cm water (<15cm)
    • Sensations of fullness ( 250cc +)
    • Initiation and maintenance of Contractions till its complete evacuation (micturation 60cm, IVP >80cm + UF <15cc/min = BOO) (BOO, VUR, diverticulum, DSD, LMNL bladder, cystocele)
    • volentarily voiding / inhibition of mict.
    • Antireflex mech
    • Contenance (trigone, neck, internal & external sphincters, urethra)
  • Micturation Reflex
    • Afferants from bladder activate sacral spinal cord centre which through their efferants cause Contraction of detrusor and relaxation of sphincters
    • Higher Centre facilitate or inhibit pons / mid brain
      • Medial pontine nuclei Micturation
      • Lateral pontine nuclei inhibition
      • DSD
  • Inability to Pass Urine
    • Retention of Urine
        • When patient, despite an urge to void, is unable to push urine out of bladder due to either infravesical obstruction or inability to generate effective detrusor contractions. Correct catheterization yields urine relieving symptoms.
    • Anuria
        • A condition when either urine is not being produced ( pre-renal & renal) or is not reaching urinary bladder (post-renal / obstructive). No urge to void. Even on correct catheterization, no urine is drained.
    • Extravasion
        • Leakage of urine into tissues / body cavity (peritoneum)
  • Types of Retention
    • Acute Retention
      • Agonizing painful condition with intense urge
      • Well defined palpable & tender bladder
    • Chronic Retention
      • Painless condition of incomplete bladder evacuation / high residual urine, (>250cc)

        • Keep Items ready
        • Theatre / dressing room / bed
        • Supine posture legs separated
        • Female – knee bent & separated, feet together
        • Gloves
  • Urethral catheterization Technique
        • Cleaning = aniseptics
        • Females – separate labia – clean from before backwards, hold till cath complete
        • Prepuse – retract & clean
        • Drape
        • instill gel – hold 2 min / clamp
        • Hold penis with non-dominent hand glans towards head end == Curve “S” ---  “U”
        • Use dominant hand for cath
        • Gently push cath - non touch technique
        • Deep / slow breathing
  • Urethral catheterization Technique
    • Relax ---------- valium
    • Push whole length in – till bifercation
    • Don’t inflate till clar urine drained
      • gel, misplaced, anuria, extravasion
      • Inflate while full length inside / pull afterwards
      • Use water = not saline
      • Don’t inflate = blood, not sure of position
    • Note color amount of urine
    • C/S
    • Post cath heamaturia - slow/ intermitant / high
  • Urethral catheterization Technique
    • Resistance -- look for help
      • refer
      • Suprapubic puncture abscess
      • Marryfield introducer
      • coude tip cath
      • trocar cath == ingram / bard
      • Open s/p
      • irethral instrumentation = bougies / optical
    • Retract prepuse back
    • Documentation of procedure
    • Exam abdomen
    • Closed drainage system
    • Antibiotecs
    • Size of cath
    • Leakage blocked / spasm
  • Chronic Retention
    • High residual volume urine , >250cc
    • Longstanding, painless, not precisely palpable, dull to percussion
    • High / low pressure ch. Retention
    • Upper tract dilatation / deterioration
    • Causes
      • Long standing BOO
      • LMNL
  • Chronic Retention
    • Treatment
      • INTERNAL CATHETERIZATION
      • NOT EXTERNAL CATH
      • CATH IS NOT A RISK FOR INFECTION, IT RATHER CURES INFECTION
      • CURE OF PYO-CYSTITIS IS DAINAGE LIKE I/D FOR ABSCESS
  • Chronic Retention
    • Complications
      • Hematuria
        • slow decompression
          • clamp / non-gravity dependant / elevate
      • Crit >200 mmole = post obst diuresis
        • Concentration ability
        • Fluid overload / backlog
        • Osmotic diuresis
      • Dehydration / ellectrolyte disturbances
        • Replacement of fluid / Na
          • ml to ml replacement on hourly basis
          • Later -- one litre less then prvious days output
          • oral / intravenous saline.
          • Potassium only if low ---- renal failure
    • Infection
  • RETENTION WITH OVERFLOW / PARADOXICAL INCONTENANCE
    • Incontinence associated with a full bladder
    • Almost same as ch. retention
