Abstract
AIMS To confirm the improved performance of the micro-hole zone catheter (MHZC) compared to a conventional eyelet catheter (CEC) in male users of clean intermittent catheterizations (CICs). METHODS Male self-catheterizing subjects, who used hydrophilic sleeved soft/flexible CIC as the only bladder emptying method, were enrolled into a multi-center, randomized, cross-over study performed across six European sites. Subjects tested the MHZC, featuring a drainage zone with 120 micro-holes and a CEC with two eyelets. The study consisted of four study visits (V0-V3), during which endpoints related to catheter performance (urinary flow-stops, bladder emptying, and intra-catheter pressure) were measured and two 4-week test periods at home (T1 and T2) where dipstick hematuria and user perception between catheters were evaluated. RESULTS Seventy-three male subjects with non-neurogenic and neurogenic bladder dysfunction (3:2) were enrolled. On average, catheterizations with the MHZC led to close to mean zero flow-stops compared to ≥1 flow-stops with the CEC, during both HCP- and self-led catheterizations (both p < 0.001). Residual urine at first flow-stop was significantly reduced for the MHZC compared to CEC (p = 0.001 and p = 0.004, for HCP- and self-led catheterizations, respectively). This was substantiated by a significantly smaller pressure peak at first flow-stop, a proxy for minimized mucosal suction (both HCP- and self-led catheterizations, p < 0.001). After home-use catheterizations, dipstick hematuria was comparable between catheters, whereas catheterizations were associated with significantly improved perception in favor of MHZC regarding bladder emptying, less blocking sensation, and improved hygienic catheterization compared to the CEC. CONCLUSION This study confirmed the evidence of improved bladder emptying with the MHZC compared to a CEC without the need to reposition the catheter. The MHZC therefore offers an enhanced benefit for the dependent CIC user securing complete bladder emptying in an uninterrupted free flow and reducing the need to reposition the catheter during emptying.

Abstract
PURPOSE To assess the performance of a new urinary intermittent catheter (IC) prototype designed with a micro-hole drainage zone compared to a conventional eyelet catheter (CEC) in terms of flow-stop, bladder emptying, and hematuria. DESIGN Randomized controlled crossover studies. SUBJECT AND SETTING The sample comprised 15 male healthy volunteers (HV) and 15 IC users, along with 15 female HV and 15 IC users. The age range was lower for HV participants than for IC users (range: 20-57 years for HV vs 21-82 years for IC users). The study setting was the Department of Urology, located in Rigshospitalet, Copenhagen. METHODS Number of flow-stop incidents, residual urine volume at first flow-stop (RV1), and dipstick hematuria were measured during and after catheterization by a health care professional (HV) and by self-catheterisation (IC-users). Results from the 3 studies were combined for HV and IC users on RV1 and number of flow-stop incidents but separated on sex. For incidents of hematuria, an effect of underlying condition was assumed, and a combined analysis on sex was performed, separating HV and IC users. RESULTS When compared to the micro-hole drainage zone design, catheterizations with CEC resulted in a significantly higher mean RV1 (mean difference: 49 mL in males and 32 mL in females, both P < .001) and average number of flow-stop incidents (8 and 21 times more frequent for males and females, respectively, both P < .001). The likelihood for hematuria was 5.84 higher with CEC than with micro-hole drainage hole design, P = .053, during normal micturition in HV postcatheterization. No serious adverse events were reported. CONCLUSION The micro-hole drainage zone catheter provides IC users fewer premature flow-stops. This design feature reduces modifiable urinary tract infection risk factors, such as residual urine and micro-trauma; additional research is needed to determine its effects on bladder health.

Abstract
Urinary tract infections (UTIs) are common and troublesome complications of clean intermittent catheterisation (CIC) in individuals suffering from incomplete bladder emptying, which may exacerbate the underlying disease and lead to hospitalisation. Aside from the design of the intermittent catheter and its handling, a recent review highlighted residual urine as one of several UTI risk factors. A new urinary intermittent catheter with multiple micro-holes has been developed for improved bladder emptying. In a controlled crossover study, adult male CIC users were randomised for a health care professional-led catheterisation with the new micro-hole zone catheter (MHZC) and a conventional eyelet catheter (CEC) in two individual test visits to compare the number of flow-stops and the residual urine at the first flow-stop as co-primary endpoints. In 42 male CIC users, the MHZC resulted in significantly fewer flow-stop episodes compared to the CEC (mean 0.17, 95% CI [0.06, 0.45] vs. mean 1.09, 95% CI [0.75, 1.6], respectively; p < 0.001) and significantly less residual urine at the first flow-stop (mean 5.10 mL, SE [1.14] vs. mean 39.40 mL, SE [9.65], respectively; p < 0.001). No adverse events were observed in this study. The results confirm the enhanced performance of the MHZC compared to a CEC, ensuring an uninterrupted free urine flow with no need to reposition the catheter until the bladder is thoroughly empty.
