Self-removal of catheter after robot-assisted radical prostatectomy: a feasibility study.

Abstract

Self-removal of urinary catheter as an option after robot-assisted radical prostatectomy (RARP) has never been explored in literature. We report the feasibility and outcome of the first study of this novel concept in our hospital. We conducted a prospective audit of self-TWOC (trial without catheter) in men who underwent consecutive RARP in our centre between April 2022 and September 2022. Men who had self-TWOC filled a questionnaire about the outcomes of self-TWOC. Carbon footprint and carbon offset for each hospital TWOC avoided were calculated. Of the 129 who underwent self-TWOC, 112 filled the questionnaire and were hence included in the final analysis. Self-TWOC was successful in all the 112 (100%) men in the study. 99.1% of men were satisfied with self-TWOC at home. We managed to avoid 79.6 ± 36.72km of travel and 77min of travel time for every self-TWOC. This also saved 85£/patient on clinic expenses and fuel cost savings of 9.87-15.99£ per patient depending on car engine size/type. The carbon footprint calculated was 20kg CO2 assuming average engine sized diesel/petrol cars and 10kg CO2 for an average UK petrol hybrid car. The calculated carbon offset per patient for diesel/petrol cars: 0.32£, petrol hybrid: 0.16£. Self-TWOC for 80-160 patients will save the carbon emissions equivalent to that of a passenger on a London-New York Trans-Atlantic flight. Self-TWOC is safe, affordable and is sustainable to the environment. Widespread acceptance of this practice change will be a small, but steady step towards greener health systems across the world.
