Alum irrigation -BLADDER HEMORRHAGE
An astringent that induces hemostasis by precipitating protein over the bleeding surface. Since it has low cell permeability, its action is limited to the cell surface and interstitial spaces.

  • Low incidence of side effects
  • Easy to administer
Usual concentration: 1 percent alum bladder irrigation (base solution usually saline or sterile water). Reserved for moderate to severe hematuria/bladder hemorrhage. Average instillation rate: 250-300 ml/hour (2.5 - 3 grams/hour). In mild cases, saline continuous bladder irrigation or suprahydration may be used.
