Investigation of Non-CE Marked Intermittent Catheters for Females

Exploratory Investigation on Performance and Safety of Newly Developed Intermittent Catheters in Female Users of Intermittent Catheters

Investigation of novel non-CE marked intermittent catheters. The study was a randomized, single blinded, cross-over investigation comparing two new catheters for females with a comparator catheter.

Study Overview

• Status: Completed
• Conditions: Retention, Urinary
• Intervention / Treatment: Device: SpeediCath® Standard female; Device: New intermittent Variant 1 catheter for females; Device: New intermittent Variant 2 catheter for females

Detailed Description

The CP324 study investigated a novel non-CE marked intermittent catheter, designed in two different variants, Variant 1 and Variant 2, respectively, and was conducted in Denmark. The study was a randomized, single blinded, cross-over investigation comparing the two new variant catheters with a comparator catheter in 15 female IC users.

For each participant, the study thus contained three test visits/treatment arms (Comparator, Variant 1 and Variant 2, respectively), to which the 15 participants were randomized using a randomization sequence of six (i.e., there were six different random options for the order in which the participants tested the three catheters). There were 4-14 days between the test visits.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Intermittent catheter; SpeediCath® Standard female; Participants underwent two catheterizations with standard of care intermittent catheter: The first was performed by a trained nurse, the second by the participant later the same day.	Device: SpeediCath® Standard female; Intermittent catheterization through the urethra draining the bladder, using SpeediCath® Standard female.
Experimental: New intermittent catheter Variant 1 for females; Participants underwent two catheterizations with the new intermittent catheter variant 1 for females: The first was performed by a trained nurse, the second by the participant later the same day.	Device: New intermittent Variant 1 catheter for females; Intermittent catheterization through the urethra draining the bladder, using the new Variant 1 catheter.
Experimental: New intermittent catheter Variant 2 for females; Participants underwent two catheterizations with the new intermittent catheter variant 2 for females: The first was performed by a trained nurse, the second by the participant later the same day.	Device: New intermittent Variant 2 catheter for females; Intermittent catheterization through the urethra draining the bladder, using the new Variant 2 catheter.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Residual Urine at 1st Flow-stop During Nurse Catheterization	The residual urine at 1st flow-stop during nurse catheterization (i.e., catheterization performed by the nurse) represents the volume of urine left in the bladder, the first time the urine stops running out of the catheter during bladder emptying/urination. This was assessed using a pressure sensor with time-logged weighing, meaning that a flow-stop was registered measuring the hydrostatic pressure at the outlet of an intermittent urinary catheter. Simultaneously, the collected urine was weighed and converted to volume, and the residual volume at first flow stop was calculated as the difference between the total urine volume collected and the volume collected at the first flow-stop.	Immediately after the procedure/catheterization, up to 5 min.
Residual Urine at 1st Flow-stop During Self-catheterization	The residual urine at 1st flow-stop during self-catheterization (i.e., catheterization performed by the participant) represents the volume of urine left in the bladder, the first time the urine stops running out of the catheter during bladder emptying/urination. This was assessed using a pressure sensor with time-logged weighing, meaning that a flow-stop was registered measuring the hydrostatic pressure at the outlet of an intermittent urinary catheter. Simultaneously, the collected urine was weighed and converted to volume, and the residual volume at first flow stop was calculated as the difference between the total urine volume collected and the volume collected at the first flow-stop.	Immediately after the procedure/catheterization, up to 5 min.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Post-void Residual Urine After Nurse Catheterization	The volume of residual urine (urine left in the bladder) post catheterization (performed by the nurse) measured in triplicates using an ultrasound scanner.	Immediately after the procedure/catheterization, up to 15 min.
Post-void Residual Urine After Self-catheterization	The volume of residual urine (urine left in the bladder) post catheterization (performed by the participant) measured in triplicates using an ultrasound scanner.	Immediately after the procedure/catheterization, up to 15 min.
Insertion Discomfort During Nurse Catheterization	Discomfort measured at catheter insertion (performed by nurse), using the Visual Analogue Scale (VAS). The VAS is a tool used to rate the intensity of certain sensations and feelings, e.g. discomfort/pain. It is a straight line of 10 cm (in this case horizontal) with one end meaning no discomfort/pain (0 cm) and the other end meaning the worst discomfort/pain imaginable (10 cm). The subject visualizes and marks a point on the line that matches the amount of discomfort/pain experienced. A high score reflects a worse outcome than a lower score.	Immediately after the procedure/catheterization, up to 5 min.
Urination Discomfort During Nurse Catheterization	Discomfort measured during catheter urination/emptying (performed by nurse), using the Visual Analogue Scale (VAS). The VAS is a tool used to rate the intensity of certain sensations and feelings, e.g. discomfort/pain. It is a straight line of 10 cm (in this case horizontal) with one end meaning no discomfort/pain (0 cm) and the other end meaning the worst discomfort/pain imaginable (10 cm). The subject visualizes and marks a point on the line that matches the amount of discomfort/pain experienced. A high score reflects a worse outcome than a lower score.	Immediately after the procedure/catheterization, up to 5 min.
Withdrawal Discomfort During Nurse Catheterization	Discomfort measured during catheter withdrawal (performed by nurse), using the Visual Analogue Scale (VAS). The VAS is a tool used to rate the intensity of certain sensations and feelings, e.g. discomfort/pain. It is a straight line of 10 cm (in this case horizontal) with one end meaning no discomfort/pain (0 cm) and the other end meaning the worst discomfort/pain imaginable (10 cm). The subject visualizes and marks a point on the line that matches the amount of discomfort/pain experienced. A high score reflects a worse outcome than a lower score.	Immediately after the procedure/catheterization, up to 5 min.
Overall Discomfort During Nurse Catheterization	Discomfort measured for the entire catheterization procedure (performed by nurse), using the Visual Analogue Scale (VAS). The VAS is a tool used to rate the intensity of certain sensations and feelings, e.g. discomfort/pain. It is a straight line of 10 cm (in this case horizontal) with one end meaning no discomfort/pain (0 cm) and the other end meaning the worst discomfort/pain imaginable (10 cm). The subject visualizes and marks a point on the line that matches the amount of discomfort/pain experienced. A high score reflects a worse outcome than a lower score.	Immediately after the procedure/catheterization, up to 5 min.
