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.
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.

Void trial failure rates
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.
Time frame: Day of surgery
Number of participants with Postoperative urinary retention (POUR)
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.
Time frame: 2 weeks and 6 weeks post surgery
Time to discharge
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.
Time frame: On the day of surgery
Number of participants with Urinary tract infection
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.
Time frame: Within 6 weeks after surgery
Incontinence Severity Index (ISI)
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
ISI total scored from 0-12, with higher score indicating more severity of symptoms.
Time frame: 2 weeks and 6 weeks post surgery
Urogenital Distress Inventory short form (UDI-6)
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.
Time frame: 2 weeks and 6 weeks post surgery
Patient Global Impression of Improvement (PGI-I)
PGI-I is scored on a 7 likert score, with total score from 1 to 7, with higher score indicating worse outcome
Time frame: 2 weeks and 6 weeks post surgery
