Void Trials After Two Voiding Trials (TVT)

Clinicaltrials.gov identifier NCT03937531

Recruitment Status Withdrawn (PI Left the Institution)

First Posted May 3, 2019

Study Description

Brief summary:

The primary objective of this project is to compare the rate of postoperative voiding dysfunction in two voiding trials (the retrograde-fill technique versus the spontaneous-fill technique) after midurethral sling (MUS) procedures with tension-free vaginal tape (TVT) without any concomitant surgery.

  • Condition or Disease:Postoperative Voiding Dysfunction
    Postoperative Urinary Retention
  • Intervention/Treatment: Procedure: Bladder Scanner
  • Phase: N/A
Detailed Description

The purpose of this research study is that the study investigators want to find out if there is a way of reducing patients' postoperative emotional stress from having a separate procedure to test their urinary function after "sling" surgery. Women with stress urinary incontinence (leakage of urine with physical activities like coughing, jumping, running, laughing, etc) may need "sling" surgery to help their urinary leakage problems. "Sling" surgeries in our hospital are mainly done using a retropubic midurethral sling (sling is passed to the space in front of your bladder). It is well known that having a sling surgery dramatically helps women with stress urinary incontinence. However, any surgical managements can have complications. One of the common complications from having a sling is "postoperative voiding dysfunction". In other words, some women may have a problem with urinating normally after the sling surgery. The most common problem is that some women (up to 4 out of 10 women) may not be able to urinate right after the surgery for the brief period of the time. The study team calls this condition "urinary retention". Postoperative urinary retention after the sling surgery can occur mainly due to pain, anesthesia effect, underlying tissue swelling; and rarely secondary to bleeding or nerve damage. Not being able to urinate for long time (>6-8 hours) can damage the bladder muscle and nerves to the bladder. Therefore, most surgeons like to perform a "bladder testing" in the recovery unit before you are ready to go home to make sure you would be able to urinate at home once discharged. Traditionally, the bladder testing is involved with back-filling the bladder with sterile water (about 300cc) and checking if the patients are able to urinate within 30 minutes. The patients should be able to urinate about two thirds of amount that has been placed in the bladder. This "bladder testing" can create a lot of emotional stress to the patients; consequently, some of the patients may not be able to urinate within the given time although there is nothing wrong with their bladder function. Those patients, who did not pass this testing, are sent home with an indwelling urinary catheter with legbag until they come back to clinic for another "bladder testing" in 3-7 days. It is well known that the indwelling catheters are a leading cause of urinary tract infection and a source of patients' discomfort, embarrassment, and inconvenience. Therefore, this study is designed to find out if having a bladder test after the sling surgery is a really-must thing to perform to test the bladder function. The study team would like to investigate if allowing the patients to have enough time to urinate their own, without making them to go through the bladder testing, would be a sufficient way of testing the bladder function after sling surgery.

Study Design
  • Study Type: Interventional
  • Allocation: Randomized
  • Intervention Model: Parallel Assignment
  • Intervention Model Description: Subjects will be enrolled consecutively during either the surgical preoperative evaluation or in the preoperative holding area before surgery. Participation in the study would not alter their surgical treatment plan. Randomization will be determined through computer-generated random number blocks of six. A sequentially numbered, opaque, sealed envelope will be opened for each subject after the recruitment and consenting process, and subjects will be assigned to one of two groups: retrograde fill void trial (RVT) vs spontaneous void trial (SVT).
  • Masking: None (Open Label) ()
  • Primary Purpose: Supportive Care
  • Official Title: Comparison of Postoperative Voiding Dysfunction in Two Voiding Trials After Retropubic Midurethral Slings: a Randomized Controlled Trial
  • Estimated Study Start Date: February 2020
  • Estimated Primary Completion Date: May 2021
  • Estimated Study Completion Date: May 2022
Arms and interventions
Arm Intervention/treatment
Experimental: Retrograde-fill void trial (RVT)
Subjects will leave the operating room with a urinary catheter inserted. Subjects should be recovered from anesthesia effects (2-3 hours after surgery) before voiding trial. First, the bladder will be completely drained into the Foley bag then the bag will be detached from the catheter. The bladder will be back-filled with sterile water (300 mL). After the catheter is removed, subjects are expected to void at least 2/3 (200 mL) of the total instilled amount within 30 minutes of filling. Post-void residual (PVR) will be measured by both subtraction of the voided volume from 300cc and by using a bladder scanner.
Procedure: Bladder Scanner
PVR will be measured by using a bladder scanner.
Active Comparator: Spontaneous void trial (SVT)
Subjects will leave the operating room without a urinary catheter. Participants are allowed up to 6 hours after surgery for spontaneous voiding. After voiding, the voided volume will be noted. PVR will be measured using a bladder scanner. In both groups, if PVR >=100 mL on a bladder scanner, an indwelling urinary catheter will be placed and the actual PVR will be documented. Subjects who failed voiding trial will be instructed to return to clinic within 2-4 days for the second void trial. Prophylactic antibiotics will NOT be given. The time to discharge will be measured for each subject. This will be determined by calculating the time between arrival to the PACU and the time of discharge using documentation from EPIC.
Procedure: Bladder Scanner
PVR will be measured by using a bladder scanner.
Outcome Measures
  • Primary Outcome Measures: 1. Void trial failure rates [ Time Frame: Day of surgery ]
    The void trial failure rates requiring postoperative urinary catheterization after midurethral sling procedures with transvaginal tape (TVT) without concomitant surgery. First, the bladder will be completely drained into the Foley bag then the bag will be detached from the catheter. The bladder will be back-filled with sterile water (300 mL). After the catheter is removed, subjects are expected to void at least 2/3 (200 mL) of the total instilled amount within 30 minutes of filling. PVR will be measured by both subtraction of the voided volume from 300cc and by using a bladder scanner.
  • Secondary Outcome Measures: 1. Number of participants with Postoperative urinary retention (POUR) [ Time Frame: 2 weeks and 6 weeks post surgery ]
    POUR any time up to 6 weeks after surgery: after discharge, subjects will be monitored for any encounters for POUR and will be asked at 2 weeks and 6 weeks post-operative visit if they have had a catheter placed outside the hospital. Additionally, any subject who fails their 2nd void trial will be noted.
  • 2. Time to discharge [ Time Frame: On the day of surgery ]
    Time to discharge will be determined by calculating the time between arrival to the PACU and the time of discharge using documentation from EPIC. Time to discharge is expected to happen on the day of surgery regardless of success or failure of void trial.
  • 3. Number of participants with Urinary tract infection [ Time Frame: Within 6 weeks after surgery ]
    UTI any time up to 6 weeks after surgery: subjects with a culture-proven UTI or >= 2 urinary symptoms (urinary urgency, frequency, dysuria, suprapubic pain, foul-smelling urine) plus pyuria on urine dip or urine analysis will be noted. Antibiotic treatment will be noted.
  • 4. Incontinence Severity Index (ISI) [ Time Frame: 2 weeks and 6 weeks post surgery ]
    ISI total scored from 0-12, with higher score indicating more severity of symptoms.
  • 5. Urogenital Distress Inventory short form (UDI-6) [ Time Frame: 2 weeks and 6 weeks post surgery ]
    UDI-6 is a 6 -item questionnaire, each item scored 0-3 with total score from 0 to 0 to 75, with higher score indicating more distress.
  • 6. Patient Global Impression of Improvement (PGI-I) [ Time Frame: 2 weeks and 6 weeks post surgery ]
    PGI-I is scored on a 7 likert score, with total score from 1 to 7, with higher score indicating worse outcome
