Intermittent Catheterization

Brief summary

This is a prospective, randomised study investigating the physical and psychological experience of intermittent catheterization in adult individuals following spinal cord injury (SCI).

Detailed description

Given that intermittent catheterization is the recommended method of bladder management in individuals with SCI, it is crucial that the potentially negative cardiovascular and psychological responses to this procedure are examined. Individuals will undergo self-catheterization, then two standard of care catheterization procedures performed by an experienced urology nurse, while either blinded to or aware of time of catheterization. Continuous cardiovascular monitoring will be in place throughout all three procedures. Assessment of anxiety will be administered pre- and post- each procedure.

Interventions

PROCEDURESelf-catheterization

Participants will perform self-catheterization, following the same routine for intermittent catheterization at home

PROCEDURECatheterization performed by urology nurse, participant blinded to time of procedure

Participant will undergo procedure to completely empty bladder; Participant in supine position, and resting blood pressure and heart rate will be recorded for period of 5 minutes prior to catheterization; Perineum and genital areas will be draped and they will be not aware about exact timing of catheterization Catheterization will be conducted following standard clinic procedure by experience urology nurse.

PROCEDURECatheterization performed by urology nurse, participant aware of time of procedure

Participant will undergo procedure to completely empty bladder; Participant in supine position, and resting BP and HR will be recorded for period of 5 minutes prior to catheterization; Perineum and genital areas will be visible to participant and they will be fully aware about exact timing of catheterization Catheterization will be conducted following standard clinic procedure by experience urology nurse.

Inclusion criteria

* Male or female, 18-70 years of age * Any chronic traumatic SCI with either motor sensory complete injury (AIS A/B, N=10) or motor sensory incomplete injury (AIS B/D, N=10). * At least 1 year post injury, and at least 6 months from any spinal surgery * Hand function sufficient to perform intermittent catheterization for management of urinary bladder drainage * Must provide informed consent and be able to understand and complete study-related questionnaires (must be able to understand and speak English or have access to an appropriate interpreter as judged by the investigator) * Willing and able to comply with clinic visit and study-related procedures

Exclusion criteria

* Signs or known current urinary tract infection, or other inflammatory conditions of bladder/urethra * Currently taking beta blockers or other medications that may affect heart rate * History of ureteral injury * History of any urinary diversion procedures, including but not limited to bladder augmentation, cystectomy, neo bladder, pouch reservoir, ileal conduit, Mitrofanoff appendicovesicostomy * For women of childbearing potential, currently pregnant * A member of the investigational team or his/her immediate family Presence of severe acute medical issue and use of any specific medication or treatment that, in the investigator's judgement, would adversely affect the participant's participation in the study

MeasureTime frameDescription
Blood pressure (BP) during self-catheterizationDuring self-catheterizationSystolic and diastolic BP (mmHg) will be measured continuously (beat-by-beat) via finger photoplethysmography, corrected to brachial pressure. BP will be measured 5 minutes prior to and then throughout the self-catheterization procedure.
Heart rate (HR) during self-catheterizationDuring self-catheterizationHR (BPM) will be recorded continuously via one-lead electrocardiogram. HR will be measured 5 minutes prior to and then throughout the self-catheterization procedure.

Change in state anxiety in the context of self-catheterization (STAIS-5)5 minutes before and 5 minutes after self-catheterizationThe State-Trait Anxiety Inventory - State, 5 item version (STAIS-5) will be used to measure participants' state anxiety prior to and after self-catheterization. Sum score of the STAIS-5 will be calculated, which ranges between 5 to 20, with higher score indicating greater state anxiety.
