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

BackgroundFoley 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.MethodsOne hundred eighty-seven patients who underwent unilateral or bilateral mastectomies with or without reconstruction in 2020 and 2021 were reviewed. Chart review included intraoperative fluids given, estimated blood loss, lymph node dissection, and duration of procedure.ResultsAfter excluding patients with case duration under 180 minutes, 145 remained. Ninety-four patients did not have a Foley and 51 patients had an intraoperative Foley. None of the patients without a Foley experienced postoperative urinary retention, including 3 patients who also underwent lymphatic microsurgical preventive healing approach. Eighty-six percent of patients were discharged on the day of surgery. Patients with or without a Foley did not differ significantly in terms of race, rate of axillary lymph node dissection, body mass index, rate of same-day discharge, presence of hypertension or diabetes, estimated blood loss, or age.ConclusionsPatients undergoing unilateral and bilateral mastectomies with or without reconstruction or lymphatic microsurgical preventive healing approach may avoid Foley catheter placement without increased risk of urinary retention, even if the case is anticipated to exceed 3 hours. Advantages include elimination of catheter-associated urinary tract infections and their associated hospital costs, as well as avoiding genitourinary trauma.
