An improper indication and subsequent management of bladder catheterization can determine up to 40% of infections related to care practices, resulting in increased morbidity and costs.In case of macrohematuria it is indicated to use catheters that have as minimum requisites the indicated size and are 3-ways silicone devices.
From this data comes the need of standardizing the knowledge and skills of all professionals who have to perform the procedure of bladder catheterization, especially in order to prevent CAUTI (Catheter Associated Urinary Tract Infections). In patient with suspected or confirmed macrohematuria, the correct choice of the device allows for an effective management of the care process, significantly reducing the occurrence of catheter obstruction, urethral trauma and /or UTI. In case these conditions arise, it is often necessary to repeat the catheterization procedure resulting in the patient’s additional exposure to the risks arising from the operation.
