Fecal Microbiota Transplantation in Treating Immune-Checkpoint Inhibitor Induced-Diarrhea or Colitis in Genitourinary Cancer Patients

This trial studies how well fecal microbiota transplantation works in treating diarrhea or colitis (inflammation of the intestines) that is caused by certain types of medications (called immune-checkpoint inhibitors) in patients with genitourinary cancer. Fecal microbiota transplantation may effectively reduce the incidence of immune checkpoint inhibitor-induced diarrhea/colitis.
