The Use of Disposable Supplies: Measuring Suburethral Sling Surgical Waste by Cost and Weight.

IMPORTANCE: The health care industry is a leading contributor to solid waste in the United States, and two thirds of a hospital's regulated medical waste is produced from surgery. OBJECTIVE: The primary objective was to assess the utilization of single-use disposable supplies during suburethral sling cases. STUDY DESIGN: We observed suburethral sling plus cystoscopy procedures at an academic medical center. Cases with concomitant procedures were excluded. Our primary outcome was the quantity of wasted supplies, defined as disposable supplies that were opened at the start of the procedure and were unused. Secondarily, we quantified those supplies in both weight and United States dollars. In a subset of cases, we obtained the weight of the total amount of trash generated from the procedure. RESULTS: A total of 20 cases were observed. Most frequently wasted items included an emesis basin, large ring basin, and rectangle plastic tray. Redundant supplies wasted included a 1-L sterile water bottle and, on average, 2.73 (SD, 2.34) blue towels. The sum of the weight of the wasted items among cases was 1.33 lb, associated with $9.50. The average total amount of trash produced from 11 cases was 14.13 lb (SD, 2.27). Removal of the most frequently wasted items would achieve a 9.4% reduction in solid waste produced by the case. CONCLUSIONS: A large waste burden per surgical case was produced by a minor procedure. Removal of frequently wasted items, a reduced number of towels, and smaller cystoscopy fluid bags are simple strategies that would decrease overall waste production.

Surgical treatment of stress urinary incontinence: comparison of robotic-assisted Burch urethropexy with retropubic midurethral sling.

Synthetic retropubic midurethral slings (RMUS) and robotic-assisted Burch urethropexies (RA-Burch) are common surgical treatment options for stress urinary incontinence (SUI). Few data exist comparing the success of these two retropubic surgeries. This retrospective cohort study of RA-Burch and RMUS procedures compared the proportion of patients with subjective cure after RA-Burch compared to RMUS at our institution between 2016 and 2020. Subjective cure was defined as reporting no symptoms of SUI at longest follow-up. Chi-square, Fisher's exact, Mann-Whitney U tests, logistic regression, and Kaplan-Meier log-rank tests were used in analyses. The overall cohort of 235 subjects included 47 RA-Burch cases matched 1:4 with 188 RMUS cases. Patients who underwent RA-Burch were younger (p < .01), had lower BMIs (p = .04), and were more likely to have concomitant procedures, including hysterectomy (p < .01). There was no difference in subjective cure at longest follow-up (p = .76). Median follow-up was longer in the RA-Burch group (p < .01). There was no difference in early postoperative complications, EBL, treatment for persistent SUI, or new urge urinary incontinence at longest follow-up. Both groups experienced postoperative urinary retention at a similar rate, although 4 RMUS patients required sling lysis and one patient experienced a mesh exposure. Patients undergoing RA-Burch had significantly longer OR times when no concomitant procedure was performed (p < .01). There were no significant predictors of SUI recurrence when controlling for baseline variables. This study suggests that RA-Burch and RMUS may be equally efficacious for patients with symptoms of SUI desiring surgical management.

Operative Time for Minimally Invasive Sacrocolpopexy: Comparison of Conventional Laparoscopy versus Robotic Platform.

STUDY OBJECTIVE: To evaluate the operative time for minimally invasive sacrocolpopexy using conventional laparoscopy vs robotic assistance. In addition, we sought to compare intraoperative complications, mesh complications, anatomic prolapse recurrence, and retreatment. DESIGN: Retrospective cohort study. SETTING: Academic hospital. PATIENTS: All 142 women who underwent minimally invasive sacrocolpopexy between January 1, 2019, and December 31, 2019. INTERVENTION: We compared operative time between laparoscopic and robotic-assisted sacrocolpopexies. MEASUREMENTS AND MAIN RESULTS: A total of 142 women were included. Mean age was 61.8 ± 9.6 years and mean body mass index 27.1 ± 4.4 kg/m2. A total of 86 (60.6%) sacrocolpopexies were performed laparoscopically and 56 (39.4%) with robotic assistance. There were no significant differences in baseline demographic variables. A higher proportion of concomitant hysterectomies were performed with robotic assistance as compared with laparoscopic cases (n = 42, 73.7% robotic vs n = 43, 50.6% laparoscopic; p <.01). Mean operative times were significantly different between robotic and laparoscopic groups (176.3 ± 45.5 minutes and 195.0 ± 45.4 minutes, p = .02). On linear regression, the variables predicting significant change in operative time were robotic assistance, concomitant hysterectomy, age, body mass index, and no resident involvement. There were no differences in intraoperative bladder or bowel injury, anatomic recurrence beyond the hymen, retreatment, or mesh complications (all p >.05). CONCLUSIONS: Contrary to previous research, the use of robotic assistance does not appear to increase operative time for patients undergoing minimally invasive sacrocolpopexy in a large academic practice.

Factors Associated With a Positive Urine Culture in Women Seeking Urogynecologic Care for Urinary Tract Infection Symptoms.

IMPORTANCE: Urinary tract infections (UTIs) are one of the most common bacterial infections and more frequently affect women than men. OBJECTIVES: Our objective was to determine clinical characteristics associated with a positive urine culture in women seeking treatment for symptoms of UTI. STUDY DESIGN: In this prospective cohort study, women seeking treatment for UTI symptoms were administered the Urinary Tract Infection Symptom Assessment questionnaire at baseline and at the time of culture results. Participants were grouped by history of recurrent UTI (rUTI) based on chart review. Our primary outcome was the proportion of "positive" urine cultures (≥10 3 colony-forming units) compared between rUTI groups. Characteristics were compared and the relative odds of a positive culture were calculated with a logistic regression model. RESULTS: Analyses included 152 women, 79 (52%) with rUTI and 73 (48%) with no history of rUTI. Overall, 90 (59.2%) had a positive culture. Participants with a positive culture were more likely to report history of rUTI ( P = 0.01). There was a 2.45-fold increased adjusted odds of a positive culture in those with a history of rUTI (adjusted odds ratio [aOR], 2.45; 95% confidence interval [CI], 1.34-5.03; P = 0.01) when controlling for confounding variables, including scores on the Urinary Tract Infection Symptom Assessment for frequency (aOR, 0.59; 95% CI, 0.40-0.91), dysuria (aOR, 1.53; 95% CI, 1.10-2.12), and age (aOR, 1.02; 95% CI, 1.01-1.05). CONCLUSIONS: In a cohort of women seeking care for UTI symptoms, older women, those with a history of rUTI and those presenting with dysuria are more likely to have a positive urine culture compared with those with urinary frequency.

Total Vaginal Hysterectomy With Uterosacral Ligament Suspension Compared With Supracervical Hysterectomy With Sacrocervicopexy for Uterovaginal Prolapse.

OBJECTIVE: To compare prolapse recurrence after total vaginal hysterectomy with uterosacral ligament suspension to recurrence after supracervical hysterectomy with mesh sacrocervicopexy for the primary management of uterovaginal prolapse. METHODS: We conducted a retrospective cohort study of women undergoing uterovaginal prolapse repair at an academic center from 2009 to 2019. Women who underwent vaginal hysterectomy with uterosacral ligament suspension or laparoscopic supracervical hysterectomy with mesh sacrocervicopexy were included. The primary outcome was composite prolapse recurrence (prolapse beyond the hymen or retreatment with pessary or surgery). Secondary outcomes included mesh complications, time to recurrence, and overall reoperation for either prolapse recurrence or mesh complication. We used propensity scoring with a 2:1 ratio of sacrocervicopexy to uterosacral suspension. RESULTS: The cohort consisted of 654 patients, of whom 228 (34.9%) underwent uterosacral suspension and 426 (65.1%) underwent sacrocervicopexy. The median follow-up was longer for the sacrocervicopexy group (230 vs 126 days, P<.001) and less than 1 year for both groups. The uterosacral group had a greater proportion of composite prolapse recurrence (14.9% [34/228] vs 8.7% [37/426], P=.02) and retreatment for recurrent prolapse (7.5% [17/228] vs 2.8% [12/426], P=.02). The uterosacral group demonstrated a shorter time to prolapse recurrence on multivariable Cox regression (hazard ratio 3.14, 95% CI 1.90-5.16). There were 14 (3.3%) mesh complications in the sacrocervicopexy group. Overall reoperation was similar between groups (4.8% [11/228] vs 3.8% [16/426], P=.51). CONCLUSION: Total vaginal hysterectomy with uterosacral ligament suspension was associated with higher rate of, and shorter time-to-prolapse recurrence compared with supracervical hysterectomy with mesh sacrocervicopexy.

A noninvasive bladder sensory test supports a role for dysmenorrhea increasing bladder noxious mechanosensitivity.

OBJECTIVE: Catheterization to measure bladder sensitivity is aversive and hinders human participation in visceral sensory research. Therefore, we sought to characterize the reliability of sonographically estimated female bladder sensory thresholds. To demonstrate this technique's usefulness, we examined the effects of self-reported dysmenorrhea on bladder pain thresholds. METHODS: Bladder sensory threshold volumes were determined during provoked natural diuresis in 49 healthy women (mean age, 24±8 y) using 3-dimensional ultrasound. Cystometric thresholds (Vfs, first sensation; Vfu, first urge; Vmt, maximum tolerance) were quantified and related to bladder urgency and pain. We estimated the reliability (1-wk retest and interrater). Self-reported menstrual pain was examined in relationship to bladder pain, urgency, and volume thresholds. RESULTS: Average bladder sensory thresholds (mL) were Vfs (160±100), Vfu (310±130), and Vmt (500±180). Interrater reliability ranged from 0.97 to 0.99. One-week retest reliability was Vmt=0.76 (95% CI, 0.64-0.88), Vfs=0.62 (95% CI, 0.44-0.80), and Vfu=0.63 (95% CI, 0.47-0.80). Bladder filling rate correlated with all thresholds (r=0.53 to 0.64, P<0.0001). Women with moderate to severe dysmenorrhea pain had increased bladder pain and urgency at Vfs and increased pain at Vfu (P's<0.05). In contrast, dysmenorrhea pain was unrelated to bladder capacity. DISCUSSION: Sonographic estimates of bladder sensory thresholds were reproducible and reliable. In these healthy volunteers, dysmenorrhea was associated with increased bladder pain and urgency during filling but unrelated to capacity. Plausibly, women with dysmenorrhea may exhibit enhanced visceral mechanosensitivity, increasing their risk to develop chronic bladder pain syndromes.
