he effect of folleys catheter size or its duration on the urine residual volume in ICU patients

For bladder catheterization which is essential in all of the ICU patients, folleys catheter is essential. The aim of catheterisation is complete drainage of urinary bladder. The folleys catheter has two lines, one for urine drainage and the other for balloon filling to prevent its unnecessary or accidental catheter exertaction.Materiala and All of the patients admitted for at least 15 days in the ICU ward of Khatamol- Anbia hospital during one year (99) were enroled in this study. The urinary catheter of all of them was manufactoral by SUPA (Iran). Urine residual volumes were measured by Bladder scan BVI 3000. The mean urine residual volumes in 3 consecutive measurements for each patient per day were 43-71 ml and the urinary catheter sizes were 6 to 20. According to repeated analysis variance of repeated measurements, there was not any significant relation between urine residual volume and duration of urinary catheterization (p=0.11). During the first 10 days there was not any significant relation between urine residual volume and urinary catheter size (0.05Conclusion
