Purple urine bag syndrome is an uncommon but particularly striking phenomenon observed in people with urinary catheters and co-existent urinary tract infections. A chemical reaction between plastic and certain bacterial enzymes results in an intense purple urine color. We report a 72 year-old male with a cystostomy. A purple coloration of his urinary drainage bag and tubing was noted in the con...

BACKGROUND Strategies to decrease use of female indwelling urinary catheters and catheter-associated urinary tract infections are challenging due to the limited availability of proper fitting external collection devices. Female urinary incontinence predisposes the skin to potential pain, itching, burning, infection, or pressure injuries. CASE STUDIES This article discusses 3 patients' traject...

Indwelling urinary catheters may act as a reservoir of bacteria and cause urinary tract infections. Removal of the bacteria adherent to a urinary catheter should reduce the incidence of catheter-associated urinary tract infections. Using several N-acylated amino acids with combinations of four different acyl residues, we investigated their efficacy in removing adherent bacteria from catheter ma...

BACKGROUND Prolonged urinary catheterization is common amongst people in long-term care settings and this carries a high risk of developing a catheter-related urinary tract infection and associated complications. A variety of different kinds of urethral catheters are available. Some have been developed specifically to lower the risk of catheter-associated infection, for example antiseptic or an...

Silicone tubing is used in small-diameter long-sized tubes for medical applications, such as urinary catheters. However, bacteria urine adhere to the catheters, forming colonies and biofilms resulting blockages tract infections. Therefore, we have reported a method of AC high-voltage plasma chemical vapor deposition prevent bacterial adhesion by depositing diamond-like carbon (DLC) on lumen sil...

Infectious biofilms are problematic in many healthcare-related devices and are especially challenging and ubiquitous in urinary catheters. This report presents an on-demand fouling-release methodology to mechanically disrupt and remove biofilms, and proposes this method for the active removal of infectious biofilms from the previously inaccessible main drainage lumen of urinary catheters. Matur...

BACKGROUND AND OBJECTIVES Biomaterials are widely used in medical devices such as urinary catheters. One of the main problems associated with long term using of the urinary catheters is biofilm formation on their surfaces. Many techniques have been presented to reduce the biofilm formation. One of the most revolutionary techniques allowing such surface fictionalization is plasma surface modific...
