ABSTRACT

INTRODUCTION AND HYPOTHESIS: Our objective was to evaluate if botox alters the urinary microbiome of patients with overactive bladder and whether this alteration is predictive of treatment response. METHODS: This multicenter prospective cohort study included 18-89-year-old patients undergoing treatment for overactive bladder with 100 units of botox. Urine samples were collected by straight catheterization on the day of the procedure (S1) and again 4 weeks later (S2). Participants completed the Patient Global Impression of Improvement form at their second visit for dichotomization into responders and nonresponders. The microbiome was sequenced using 16s rRNA sequencing. Wilcoxon signed rank and Wilcoxon rank sum were used to compare the microbiome, whereas chi-square, Wilcoxon rank sum, and the independent t-test were utilized for clinical data. RESULTS: Sixty-eight participants were included in the analysis. The mean relative abundance and prevalence of Beauveria bassiana, Xerocomus chrysenteron, Crinipellis zonata, and Micrococcus luteus were all found to increase between S1 and S2 in responders; whereas in nonresponders the mean relative abundance and prevalence of Pseudomonas fragi were found to decrease. The MRA and prevalence of Weissella cibaria, Acinetobacter johnsonii, and Acinetobacter schindleri were found to be greater in responders than nonresponders at the time of S1. Significant UM differences in the S1 of patients who did (n = 5) and did not go on to develop a post-treatment UTI were noted. CONCLUSIONS: Longitudinal urobiome differences may exist between patients who do and do not respond to botox.

ABSTRACT

IMPORTANCE: Conservative therapy is effective for the treatment of overactive bladder (OAB) but may be limited by accessibility to care. OBJECTIVE: The objective of this study was to evaluate the efficacy of a digital conversational agent (CeCe) for the treatment of OAB. STUDY DESIGN: This was a prospective observational trial utilizing a digital conversational agent developed by Renalis University Hospitals (Cleveland, Ohio) for the treatment of OAB. Patients were given access to CeCe over an 8-week period and were instructed on how to perform bladder training and pelvic floor exercises and taught about bladder health. The primary outcome was a decrease in the International Consultation on Incontinence-Overactive Bladder Quality-of-Life Questionnaire (ICIQ-OAB-QoL) score from week 1 to week 8. Patients also completed the 36-item Short-Form Health Survey and Generalized Anxiety Disorder Questionnaire at the same intervals and voiding diaries at weeks 1, 4, and 8. A power analysis was performed and determined that a total of 30 patients would be needed to demonstrate a significant difference in symptom scores after use of CeCe with 80% power and an α error of 5%. RESULTS: Twenty-nine patients completed all data collection. The ICIQ-OAB-QoL scores were significantly different between weeks 1 and 8 (62 [IQR], 49-75) vs 32 [IQR, 24-43]; P < 0.001). Patients also reported a decrease in frequency pretreatment and posttreatment (7 [IQR, 6-10] vs 5 [IQR, 4-7]; P = -0.04), nocturia (2 [IQR, 1-3] vs 1 [IQR, 1-2]; P = 0.03), and urge urinary incontinence (2 [IQR, 1-5] vs 0 [IQR, 0-3]; P = 0.04). Consumption of alcohol decreased from week 1 to week 8 (24 oz [IQR, 12-36 oz) to 14 oz (IQR, 9-22 oz]; P = 0.02). CONCLUSION: The use of a digital conversational agent effectively reduced the severity of symptoms and improved quality of life in patients with OAB.

ABSTRACT

BACKGROUND: It is well known that, in general, total laparoscopic hysterectomy is associated with less perioperative morbidity compared with total abdominal hysterectomy. However, total laparoscopic hysterectomy is also associated with longer operating times, which itself is an independent predictor of morbidity. Currently, it is unknown whether there is an operative time threshold beyond which total laparoscopic hysterectomy provides a diminishing return and higher risk of morbidity than a shorter abdominal hysterectomy. OBJECTIVE: This study aimed to determine whether there is an operative time limit beyond which the benefits of total laparoscopic hysterectomy diminished compared with shorter total abdominal hysterectomy. STUDY DESIGN: Targeted hysterectomy-specific data from the National Surgical Quality Improvement Project was used to identify patients undergoing total laparoscopic hysterectomy and total abdominal hysterectomy for benign indications between the years 2014 and 2018. The primary outcomes of interest were any major morbidity, and the length of stay after surgery was analyzed using generalized linear models. The models controlled for demographic data, comorbidities, and hysterectomy-specific information, such as uterine weight, presence of endometriosis, and pelvic inflammatory disease at the time of surgery. Missing data were addressed using multiple imputation analysis. Sensitivity analyses using propensity score matching and generalized additive models were performed to assess the effect of selection bias and nonlinear interactions between covariates and the outcomes, respectively. Common Procedural Terminology codes were used to identify women who underwent total abdominal hysterectomy (n=58,152) or total laparoscopic hysterectomy (n=58,570-58,573). Conventional laparoscopy could not be differentiated from robotic surgery as there is no mechanism for doing so within the National Surgical Quality Improvement Project. Therefore, total laparoscopic hysterectomy also includes robotic-assisted surgery. Additional exclusion criteria included any surgery lasting >360 minutes, as these represent significant outliers in the data and clinical practice; pelvic reconstructive procedure; anti-incontinence surgery; lymphadenectomy; radical hysterectomy; cytoreductive surgery; a pre- or postoperative diagnostic code for gynecologic malignancy; preoperative sepsis or renal failure; emergency surgery; or any concurrent nongynecologic surgery. Patients who underwent ureteral stenting during the procedure with no additional urologic procedures were included, as this may be performed at the time of hysterectomy or to address ureteral injury. RESULTS: The mean operating time was similar for both routes, 129±60 minutes for total laparoscopic hysterectomy and 129±64 minutes for total abdominal hysterectomy (P=.45). The complication rate was higher for total abdominal hysterectomy than total laparoscopic hysterectomy (16.6% vs 7.7%; P<.001); and the median length of stay was longer for total abdominal hysterectomy (2 [interquartile range, 2-3] days vs 1 [interquartile range, 0-1] days; P<.001). After adjusting for confounders, an increase of 1 hour in operative time for hysterectomy was associated with a 45% (95% confidence interval, 41%-49%) increase in the risk of major morbidity; furthermore, total abdominal hysterectomy was associated with an additional time detriment, such that there was an additional 61% (95% confidence interval, 53%-68%) increase in the risk of a major morbidity for each additional hour of a total abdominal hysterectomy. There was no time point at which total abdominal hysterectomy was associated with less morbidity or a shorter length of stay than total laparoscopic hysterectomy, even if total laparoscopic hysterectomy was significantly longer than total abdominal hysterectomy. The same conclusions remained true with the propensity-matched analysis and generalized additive model analyses. CONCLUSION: Our findings showed that there is no reasonable operative time at which total laparoscopic hysterectomy is associated with a higher rate of complications or longer length of stay than total abdominal hysterectomy.
