Product evaluation of the Luja Micro-hole Zone Technology in clean intermittent self-catheterisation

Clean intermittent self-catheterisation is a common procedure undertaken by people with bladder dysfunction. However, it is not without its complications, the main one being urinary tract infection. The most common causes of urinary tract infections are poor hygiene, technique and adherence, excessive post-void residual urine and bladder trauma. A catheter with new Micro-hole Zone Technology has been developed, which can potentially improve bladder emptying and minimise these complications. A case study is used to illustrate its effects in practice.

Clean intermittent self-catheterisation (CISC) involves passing a hollow tube (catheter) into the bladder to drain off urine when clinically indicated, with the tube removed immediately. This procedure, also known as intermittent self-catheterisation, was developed by Jack Lapides more than 50 years ago (Lapides et al, 1972; Angermund et al, 2021). Before this development, indwelling urinary catheters were the norm and these brought about numerous complications, especially urinary tract infections (UTIs) (Broom et al, 2022).

While CISC has been recognised as the gold standard (National Institute for Health and Care Excellence (NICE), 2015) for draining a dysfunctional bladder, the devices bring their own risks and complications including UTIs. While several systematic reviews (Rognoni et al, 2017; Shamout et al, 2017), cohort studies (Chartier-Kastler et al, 2022) and guideline summaries (Campeau et al, 2020) have attempted to identify the effectiveness of different types of CISC catheters in reducing catheter-associated urinary infections (CAUTIs), very little good-quality evidence is available apart from a review by Barken and Vaabengaard (2022), which identified that catheters with a hydrophilic coating were more effective in preventing CAUTIs than non-hydrophilic ones.
