TURP and TURP syndrome

Learning objectives

  • Definition of transurethral resection of the prostate (TURP) syndrome 
  • Management of TURP

Definition and mechanisms

  • Benign prostatic hyperplasia (BPH) occurs in over
  • 40% of men aged over 60 years and prostate resection is the second-line treatment if BPH symptoms are resistant to medical management
  • Transurethral resection of the prostate (TURP) syndrome is a rare but potentially life-threatening complication of transurethral resection of the prostate procedure
  • During the procedure, the prostate at the bladder neck is shaved away
  • As the body of the prostate is removed, veins are exposed, but the capsule is maintained
  • The exposed veins can bleed, causing significant blood loss, and can also absorb large amounts of irrigation fluid resulting (1.5% glycine solution) in TURP syndrome
  • Treatment is largely supportive and relies on the removal of the underlying cause and organ and physiological support
  • Mortality is 0.2-0.8%
  • Pre-operative prevention strategies are extremely important

Signs and symptoms

Central nervous systemRestlessness

Cerebral edema
Seizures
Coma
Cardio-respiratoryBradycardia
Hypotension or Hypertension
Tachypnea
Hypoxia

Pulmonary edema
SystemicHypothermia
Abdominal pain and distension

Complications of TURP procedure

  • Retrograde ejaculation
  • Urinary incontinence
  • Erectile dysfunction
  • Urethral strictures (narrowing of the urethra)
  • Bleeding
  • Urinary tract infection
  • Urinary retention

Risk factors

  • The size of the opened venous sinuses
  • The amount of irrigation fluid used
  • The use of excess amounts of hypotonic intravenous fluids
  • Duration of the resection (> 1 hour)
  • Perforation of the bladder

Diagnosis

Prevention

  • Regional anesthesia is preferred over general anesthesia
  • Avoid large amounts of glycine-containing fluid infusion
  • Keep the length of surgery under 1 hour
  • Keep the patient horizontal and avoid the Trendelenburg position
  • Resect large prostates in staged procedures to avoid prolonged operative times
  • The optimal height of the irrigation fluid bag above the patient is 60 cm

Management

TURP and TURP syndrome, neuraxeal anesthesia, irrigation fluid, general anestehsia, spinal anesthesia, CVP, hyponatremia, anemia

Treatment of TURP syndrome

  • Stop the procedure as soon as possible
  • Provide oxygenation (intubation) & circulatory support (inotropes)
  • Perform invasive monitoring if hemodynamically unstable
  • Treat hypotension
  • Correct hyponatremia
  • Treat fluid overload with diuretics
  • Manage disseminated intravascular coagulation
  • Perform regular blood tests to monitor improvement in the clotting status
  • Control seizures with benzodiazepines
  • Treat nausea and vomiting with antiemetics
