Dosage and Side Effects

  • Pre-Instillation Preparation: Take 1.3 grams of sodium bicarbonate orally the night before, in the morning, and 30 minutes before the instillation procedure. This adds up to a total of 3.9 grams.
  • Installation Dosage: The recommended dose of Mitomycin to be instilled is 4 milligrams per milliliter through a ureteral catheter or nephrostomy tube. The total instillation volume should be determined using pyelography measurements, capped at 15 milliliters (equivalent to 60 milligrams of Mitomycin).
  • Treatment Schedule: Administer Mitomycin 40 mg once a week for six weeks. If a patient shows a complete response three months after starting Mitomycin, subsequent installations may be given once a month for a maximum of 11 additional sessions.
