Omitting Foley Catheter Use in Mastectomy Patients With or Without Immediate Reconstruction.

Background: Foley catheter placement is often advised in surgeries anticipated to exceed 3 hours; however, this time cutoff does not take into account the type of surgery. Complications from Foley catheter placement include urinary tract infections and genitourinary trauma that may be costly to healthcare systems. Our objective was to determine whether mastectomy with or without reconstruction can be done without Foley use, without an increase in urinary retention risk.
