Comparison of urinary flow with two female intermittent catheters

Comparison of Urinary Flow Speed Using 14 Fr Two Eyelet Coloplast Female SpeediCath Urinary Catheter Versus 14 Fr Coloplast Micro Zone Luja Female Catheter in Female Patients Using Intermittent Catheters

Not applicable Interventional Wake Forest University Health Sciences · NCT06918067

This test will see if two different female intermittent catheters produce different urinary flow speeds in adults who regularly catheterize.

What this trial studies

This is a randomized crossover comparison of two 14 Fr female catheters made by Coloplast, the Two Eyelet SpeediCath and the Micro Zone Luja. Participants are randomly assigned to one of two sequences, self-catheterize with the first device, have the bladder backfilled with sterile fluid equal to the urine collected, then self-catheterize with the second device. Urinary flow outcomes are measured during a single office visit using an uroflowmetry device, and participants receive a follow-up phone call about one week later. The crossover design lets each participant serve as her own control to compare flow speed between the two catheters.

Who should consider this trial

Good fit: Women aged 18 or older who have been regularly using intermittent catheterization for at least one month and can attend a single in-person visit are ideal candidates.

Not a fit: People with severe urinary tract abnormalities, current urinary tract infection, recent surgery, pregnancy or breastfeeding, hypersensitivity to catheter ingredients, or inability to follow the procedures may not receive benefit or be eligible.

Why it matters

Potential benefit: If successful, the results could help people who catheterize choose a catheter that empties the bladder faster or more efficiently.

How similar studies have performed: Prior crossover comparisons of catheter designs have been performed and sometimes show small differences in flow or usability, so this approach builds on modest prior evidence rather than being entirely novel.
