title: [Evaluation of the irrigation and drainage capacity of 3 bladder irrigation catheters].
abstract: OBJECTIVE
  To perform a comparative evaluation of three types of continuous bladder irrigation catheters with the aim of determining which of them allows greater irrigation solution inflow and bladder outflow.
  
  
  METHODS
  We compared three types of three-way catheters, 22F in caliber, being the material the main difference between them: latex, silicone, or polyvinyl.
  
  
  RESULTS
  The polyvinyl catheter showed significant differences both in inflow and outflow in comparison with the other two types of catheters (p = 0.000, ANOVA test with Sheffe's post hoc). Additionally, the latex catheter showed a significant outflow decrease with the insufflation of the self retentive balloon.
  
  
  CONCLUSIONS
  The polyvinyl catheter, due to material rigidity, is the one that allows better bladder irrigation.
