BACKGROUND: Indwelling Foleys catheter does continuous urinary drainage in the postoperative period of patients undergoing obstetric and gynecological surgeries. AIMS and OBJECIVES: To study the rate of postoperative catheter induced bacteriuria in obstetric and gynecological surgeries using variables such as duration of catheter insitu, type of bacteriuria, type of surgery and most common organism isolated. METHODS : This study is a retrospective observational study done over a period of 2 months from March 2019–April 2019 in which 64 patients were enrolled. The variables studied are rate of catheter induced bacteriuria, common organisms isolated, rate of bacteriuria associated with duration of catheterization . RESULTS: Rate of catheter induced bacteriuria was 32.8%.Most common organisms isolated were E.coli, Klebsiella, Pseudomonas. Bacteruria was 15.38% when duration of catheterization was 24 hrs, 35% when duration of catheterization was 48 hrs and 55.5% when duration of catheterization was 72 hrs. CONCLUSIONS: It is better to avoid catheterization. Duration of catheterization should be reduced to minimise catheter induced bacteriuria and associated morbidity, prolonged hospital stay after surgery.
