If hematuria occurs after chemotherapy, it depends on what the cause of the hematuria is as to how many days it takes to heal after treatment. If the cause of hematuria is the suppression of bone marrow hematopoietic function after chemotherapy, the decrease of platelet count in peripheral blood, and bleeding in the urinary tract, the hematuria can be stopped immediately after the platelet count of blood recovers to a certain level after the transfusion of machine collected platelet suspension. Even without platelet transfusion, the hemorrhage can be stopped by itself when the bone marrow hematopoietic function recovers and the platelet count returns to normal about 14 days after chemotherapy. If the cause of hematuria is a certain chemotherapy drug, such as cyclophosphamide which can lead to hemorrhagic cystitis and cause hematuria, it can also be relieved within a few days usually by using antidotes such as sodium mesylate and also by hydrating and alkalizing the urine with a lot of water and alkaline supplementation. There are also some rare causes, such as chemotherapy that damages the glomerulus, leading to glomerulonephritis, causing hematuria and proteinuria, which are more troublesome to treat and usually take weeks or even months to slowly resolve after regular specialist treatment.
