Sterile Single-use vs Reused Polyvinylchloride Catheter For Intermittent Catheterization In Neurogenic Bladder

The objective of the study is to determine whether single-use polyvinylchloride (PVC) catheters reduce urinary tract infections (UTI) compared to reused PVC catheters for patients with neurogenic bladder due to spina bifida that require intermittent catheterization for bladder emptying. The investigators conducted a clinical trial with an 8-week follow-up comparing single-use and reused (washed with soap and water, and stored in a container with benzalkonium chloride or washed with soap and water alone) PVC intermittent catheterization. Evaluations were established on days 0, 7, 14, 28, 42, and 56. Participants reported symptoms and urine culture results, collecting urine samples from a fresh midstream catheter specimen using a sterile technique.
