Abstract

Introduction: Premature deflation and spontaneous expulsion of the Foley catheter is detrimental to outcome of surgeries. Previous studies have compared latex with silicon and also evaluated various types of fluid used to inflate the bulbs of Foley catheters. We hypothesized that deflation rates would vary between different brands of Foleys available and the rate would also vary with time.
Materials and Methods: Eight different brands of 14-French 45 cm long Foley silicone catheters were used. Bulbs were inflated with the 10 mL of saline solution. The widest point, vertically and horizontally was measured. Each bulb was completely submerged into a sterile urine bath at 38°C. Every alternate day bulbs were removed from the urine bath. Vertical and horizontal measurements were recorded for each bulb and the catheters were replaced in the bath. This procedure was repeated for 28 days.
Results: The correlation of “deflation rates of silicon Foley’s bulb” provided by 7 companies was calculated with respect to each other and with respect to time. It was found that all the different silicon Foleys showed significant positive correlation with each other (p<0>
Conclusion: The deflation of bulb and spontaneous expulsion of Foleys does not vary among commonly available brands. Additional measures like hitching the catheter to glans penis may be used if prolonged (greater than 7 days) catherization is necessary.
