RESUMEN
AIMS: To evaluate the impact of a protocol for standardized image capture during video urodynamics (VUD) on radiation exposure. Secondly, to categorize radiation exposure by condition warranting VUD and to identify clinical variables that correlate with increased radiation exposure. METHODS: One hundred fifty patients underwent VUD using our standardized protocol. All images were taken using low dose and pulsed settings. Four images are captured: one scout image, one filling image, one voiding image, and one post-void image. If the patient is unable to void with the catheter in place, the catheter is removed and a second image is taken during an attempt at unintubated flow. If vesicoureteral reflux (VUR) is identified, an alternate protocol is entered to document parameters. The mean radiation exposure measured in dose area product (DAP), fluoroscopy time, and number of images were noted and compared with previously published fluoroscopy data collected at our institution before protocol implementation. RESULTS: The mean fluoroscopy exposure after the implementation of our protocol was 273.5 mGy/cm2 taking 5.2 images in 4.5 seconds. Protocol implementation leads to a 51.2% reduction in radiation exposure calculated by mean DAP (P < .0001) and a 96.5% reduction in fluoroscopy time (P < .0001). The presence of VUR, fluoroscopy time, and body mass index (BMI) > 25 were associated with higher radiation exposure (P < .0001). CONCLUSION: Implementation and adherence to a standardized protocol for fluoroscopy led to a reduction in radiation exposure fluoroscopy time. The presence of VUR, fluoroscopy time, and BMI > 25 were associated with higher radiation exposure.

IMPORTANCE: Adherence to overactive bladder (OAB) therapy is low among the general population. Prior studies suggest that OAB is more prevalent among Hispanic women compared with other ethnicities. OBJECTIVES: The aims of this study were to analyze nonadherence to OAB therapy among Hispanic compared with non-Hispanic women and identify potential barriers to treatment to reduce disparities in care. STUDY DESIGN: All patients who received treatment for OAB between 2018 and 2022 were included in this retrospective study. Race and ethnicity were self-reported. Nonadherence was defined as failure to initiate therapy within 1 year. Non-Hispanic women were selected at random to form a control group. The study was powered to detect a 50% difference in treatment nonadherence. Comparisons were made using the Fisher exact test or χ2 test as appropriate for nominal variables, and the Mann-Whitney test for continuous variables. RESULTS: The analysis included 126 Hispanic and 126 non-Hispanic women. Both cohorts were similar in demographics. Nonadherence to OAB therapy was more frequent among Hispanic women (44.0 vs 20.9%, P < 0.0001). After adjusting for age, body mass index, primary language, parity, insurance type, and treatment offered, Hispanic women were at a 2.54-fold increased risk of nonadherence (P = 0.007). A subanalysis of only Hispanic women found that younger age (P = 0.033), higher parity (P = 0.035) underinsured status (P = 0.027), and fewer office visits (P = 0.0002) were associated with nonadherence. CONCLUSIONS: Nonadherence to OAB therapy was greater among Hispanic women despite no difference in treatment patterns. Younger age, greater parity, lack of insurance, and fewer office visits may be barriers for Hispanic women.
RESUMEN
OBJECTIVES: To evaluate whether progression to maintenance percutaneous tibial nerve stimulation (PTNS) was related to perceived global impression of improvement (PGII) rather than symptom-specific improvement in patient with overactive bladder (OAB). We hypothesize that PGII will predict continuation of PTNS long-term. METHODS: This prospective observational study included 90 patients with OAB that initiated PTNS. The PGII and OAB short-form questionnaires (OABq-SF) were used to assess bladder symptom severity and improvement. Those that completed the 12-week induction phase were offered to continue PTNS monthly maintenance or pursue other options. The primary outcome was difference in PGII score between those pursuing maintenance therapy versus other options. Descriptive statistics and mixed effect modeling analysis were employed. RESULTS: Seventy patients (78%) completed 12 weeks of PTNS. The majority of completers pursued monthly maintenance (P< .01) and had significantly lower median PGII scores compared with those who sought alternatives (P < .01), while OABq-SF scores did not differ significantly (P = .65). Patients that pursued monthly PTNS maintenance had lower body mass index than those who chose alternative therapies (P < .01). Only 19% continued PTNS therapy for at least 1 year. CONCLUSION: More patients pursued PTNS monthly maintenance over any other therapy, and this was significantly associated with lower PGII scores. Global improvement, and not symptom-specific response, predicts long-term PTNS maintenance. No symptom-specific predictors were identified in those who pursued maintenance over other options. One-year continuation rates are low.

PURPOSE: To evaluate if question phrasing and patient numeracy impact estimation of urinary frequency. MATERIALS AND METHODS: We conducted a prospective study looking at reliability of a patient interview in assessing urinary frequency. Prior to completing a voiding diary, patients estimated daytime, and nighttime frequency in 3 ways: (1) how many times they urinated (2) how many hours they waited in between urinations (3) how many times they urinated over the course of 4 hours. Numeracy was assessed using the Lipkus Numeracy Scale. RESULTS: Seventy-one patients completed the study. Correlation of estimates from questions 1, 2, and 3 to the diary were not statistically different. Prediction of nighttime frequency was better than daytime for all questions (correlation coefficients 0.751, 0.754, and 0.670 vs 0.596, 0.575, and 0.460). When compared to the diary, Question 1 underestimated (8.5 vs 9.7, P = .014) while Question 2 overestimated (11.8 vs 9.7, P = .027) recorded voids on a diary. All questions overpredicted nighttime frequency with 2.6, 2.9, and 3.9 predicted versus 1.6 recorded voids (P < .001). Although not statistically significant, for each question, the predicted frequency of numerate patients was more correlated to the diary than those of innumerate patients. CONCLUSION: When compared to a voiding diary for daytime urinary frequency, asking patients how many times they urinated underestimated, and asking patients how many hours they waited between urinations overestimated the number recorded voids. Regardless of phrasing, patients overestimated nighttime urination. Patients in our functional urology population have limited numeracy, which may impact accuracy of urinary frequency estimation.

Injury to the urinary tract is a known risk of surgical repair of anterior and apical pelvic organ prolapse. Cystoscopy at the time of surgical prolapse repair is a low-risk procedure that can identify genitourinary tract injury by inspecting the bladder and urethra as well as by visualizing the ureters and ureteral efflux. There are several techniques to assist with visualization of ureteral efflux. Identifying injury intraoperatively may allow for mitigation of the morbidity of the injury. Universal cystoscopy should be performed at the time of all pelvic reconstructive surgeries, with the exception of operations solely for posterior compartment defects.
