Urinary Catheter Self-Discontinuation After Urogynecology Surgery
A study testing Catheter self-discontinuation in people with Urinary Retention and Pelvic Organ Prolapse, run by University of Texas at Austin at 4 sites in United States.
Trial summary
The goal of this randomized clinical trial is to determine if removal of transurethral urinary catheters by patients at home is as safe as catheter removal in the office following urogynecologic surgery.

About this study
The goal of this randomized clinical trial is to determine if removal of transurethral urinary catheters by patients at home is as safe as catheter removal in the office following urogynecologic surgery.
Participants will be randomized to either standard catheter removal in the office or catheter self-removal at home.
Read the detailed description
This is a prospective, randomized, two-parallel arm, non-inferiority trial to evaluate two methods of catheter discontinuation in women with post-operative urinary retention (POUR) after surgery for pelvic organ prolapse (POP) or stress urinary incontinence (SUI). This study will evaluate whether self-discontinuation of transurethral catheter by patients is non-inferior to standard office discontinuation based on rates of persistent POUR on post-operative day (POD) 1.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Catheter self-discontinuationProcedure or surgery
Self-discontinuation of a transurethral catheter
| Study group | Role | What they receive |
|---|---|---|
| Catheter office-discontinuation group | No intervention | The patients randomized to the office-discontinuation group will visit the office for a repeat voiding trial on postoperative day 1. At this visit, the patients will undergo a backfill voiding trial. |
| Catheter self-discontinuation group | Experimental | The patients randomized to the catheter self-discontinuation group will be provided with a diagrammatic handout and will be instructed to remove their indwelling urinary catheter at home on the morning of Postoperative day 1. Receives: Procedure: Catheter self-discontinuation |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With Postoperative Urinary Retention
Non-inferiority comparison of the rates of persistent POUR on POD1 between catheter self-discontinuation and standard office catheter. Persistent POUR is defined as PVR greater than 100 mL by bladder scan on POD1.
Measured: Post-operative day 1
Secondary outcomes (5)
Rates of postoperative urinary tract infection (UTI)
Rates of postoperative UTI within 6 weeks of surgery - UTI will be defined as treatment with antibiotics for symptoms of UTI.
Measured: within 6 weeks of surgery
Incidence of recurrent POUR
Recurrent POUR will be defined as any participant with successful POD1 voiding trial who later requires replacement of catheter due to recurrent POUR within 6 weeks of surgery. Recurrent POUR is defined as PVR greater than 100 mL by bladder scan after passing initial POD1 voiding trial.
Measured: within 6 weeks of surgery
Number of postoperative patient encounters
Number of postoperative patient encounters, including any patient call to the office, electronic medical record message to office from patient, office visit, or emergency department visit.
Measured: within 6 weeks of surgery
Patient satisfaction assessment via the Acceptability of Intervention Measure (AIM) Questionnaire
Patient satisfaction with catheter removal method as assessed via the Acceptability of Intervention Measure (AIM) Questionnaire.
The AIM Questionnaire is a 4-item questionnaire on a 5-point Likert scale. Response Scale: 1 = Completely disagree, 2 = Disagree, 3 = Neither agree nor disagree, 4 = Agree, 5 = Completely agree Scoring Instructions: Scale is created by averaging responses. Scale values range from 1 to 5.
The higher the score is, the higher the degree the patient finds the intervention acceptable.
Measured: Post-operative day 1
Patient satisfaction assessment via the the Surgical Satisfaction Questionnaire - 8 (SSQ-8).
Patient satisfaction with catheter removal method as assessed via the Surgical Satisfaction Questionnaire - 8 (SSQ-8).
The SSQ-8 is an 8-item questionnaire, with responses recorded on a 5-point Likert scale with responses from 0 "Very Unsatisfied" to 4 "Very Satisfied." Scoring uses the mean average of the 8 scores being multiplied by 25 (the questionnaire is considered incomplete if more than 2 items are not answered), yielding a potential range of scores from 0 to 100. The higher the score is, the greater the degree of surgical satisfaction.
Measured: Post-operative day 1
