Introduction Out‐of‐hospital community births account for 1.6% to 2% of births in the United States and are associated with fewer obstetric interventions but increased neonatal risk. Little is known about how maternity care providers’ characteristics, values, and prior exposure to community birth influence attitudes toward community birth. Methods We conducted an observational cross‐sectional survey using a 40 to 43 item Research Electronic Data Capture questionnaire distributed October 2 to 30, 2024. Eligible participants (“providers”) included in‐hospital physicians, midwives, community birth providers, and registered nurses. The survey assessed demographics, practice characteristics, provider values, prior community birth experience, and attitudes toward community birth. Descriptive statistics were used to summarize characteristics. Group comparisons between in‐hospital and community birth providers were conducted using analysis of variance and χ 2 or Fisher exact tests. Associations between attitudes and provider values were evaluated using linear models with Bonferroni correction. Results Sixty‐seven providers completed the survey (51 in hospital, 16 community based). Most respondents were female (89.6%) and White (77.6%), with a median of 7 years in practice (IQR, 3‐14.5). Attitudes significantly differed by role ( P = .007) and credentials ( P = .002). In‐hospital providers reported safety concerns about community birth and perceived antenatal counseling to be inadequate. Perceived patient distrust during transfer was common among both in‐hospital and community‐based providers (69% and 81%, respectively). After adjustment for provider role and multiple comparisons, no significant differences in personal values were noted by attitude group; however, providers with positive attitudes toward community birth were more likely to believe that patients value compassion (β = 2.3, P = .004). Discussion Provider attitudes toward community birth appear to be shaped more by professional role and clinical experience than by differences in underlying value systems. High levels of perceived patient distrust during transfer highlight the need for interventions that strengthen compassion across maternity care settings.

Objective: To evaluate factors associated with the conversion of robotic-assisted partial nephrectomy (RAPN) to open partial nephrectomy (OPN) and radical nephrectomy (RN). Methods: We retrospectively reviewed 775 consecutive RAPNs from a single surgeon. Perioperative factors were evaluated for association with RAPN conversion such as Mayo Adhesive Probability (MAP) score, length of stay (LOS), and operative time (OT). A logistic regression model was utilized to evaluate factors associated with conversion and reported as odds ratio (OR) with 95% confidence intervals. Continuous and categorical variables were analyzed through the Wilcoxon rank-sum and chi-square tests. Results: Thirty-two (4.1%) patients had a conversion including 19 (2.5%) to OPN and 13 (1.7%) to RN. OPN conversions were related to bleeding ( n = 7), inability to dissect perinephric fat ( n = 4), liver retraction ( n = 1), and failure to secure renal hilum/progress ( n = 7). In contrast, conversions to RN were due to tumor involvement of the renal vein ( n = 3) or ureter ( n = 5) and inability to achieve negative margins ( n = 5). Patients in the conversion cohort were more likely to have larger tumor size (3.7 vs 2.8 cm; p < 0.001) and higher MAP score (3.0 vs 2.0; p = 0.04). Median LOS was higher in the conversion group (3.0 vs 2.0 days; p = 0.003). Conversions were associated with postoperative complications (28.1% vs 13.7%; p = 0.023). After adjusting tumor size in our regression model, longer OT and dissection time were statistically higher in the conversion group (OR = 2.19 [1.50–3.21]; p < 0.001 and OR = 2.67 [1.82–3.94]; p < 0.001, respectively). Conclusions: Larger tumor size and higher MAP score were associated with conversions during RAPN. Conversions were associated with higher LOS, longer OT, and postoperative complications.

Introduction: To analyze the association of patient characteristics on operating room (OR) times for robotic-assisted partial nephrectomies (RAPNs). Methods: In total, 248 consecutive RAPNs were performed by a single surgeon from October 2018 to August 2022. Data were collected on the following patient factors: sex, age, race, weight, body mass index (BMI), diabetes, hypertension (HTN), tumor side, tumor mass, and American Society of Anesthesiologists (ASA) score. Total fixed OR times were evaluated as the sum of in-room time to anesthesia-release time (IRAT), anesthesia-release time to cut time (ARCT), close time to wheels out time (CTWO), and in-room time to cut time (IRAT + ARCT). Total variable OR times were defined as cut time to close time (CTCT). Total operative time was defined as wheels into wheel out (WIWO). Results: Median OR time was 265 minutes (interquartile range [IQR]: 247–298 minutes) for WIWO, 191 minutes (IQR: 170–225 minutes) for CTCT, and 75 minutes (IQR: 68–83 minutes) for total fixed time. There was a significant increase in WIWO with the following patient variables: male sex (18.0 minutes, 95% confidence interval [CI]: 6.3–29.7 minutes), weight (5.6 minutes, 95% CI: 2.8–8.4 minutes), BMI (14.3 minutes, 95% CI: 4.2–24.4 minutes), HTN (15.1 minutes, 95% CI: 3.7–26.5 minutes), pathology tumor size (cm) (6.4 minutes, 95% CI: 2.2–10.6 minutes), and ASA score (13.8 minutes, 95% CI: 3.1–24.4 minutes). Sex, age, BMI, weight, HTN, and pathology tumor size significantly impacted CTCT ( P < 0.05). Total fixed OR time was only affected by ASA score ( P = 0.02). Conclusions: Patient variables significantly affect total OR time and variable OR time. These variables do not impact total fixed OR times, confirming fixed OR time as a viable OR efficiency point.

Abstract Introduction Erectile dysfunction continues to be a concern for patients and physicians after surgical treatment of prostate pathology. Objective To analyze doppler diagnosis on patients who underwent prostate surgery for benign or malignant pathology of the prostate. Methods We retrospectively analyzed all patients who underwent either robotic assisted prostatectomy (RALP), open retropubic prostatectomy (RRP), endoscopic procedures such as greenlight procedure, laser resection of the prostate or transurethral resection of the prostate (TURP); and High Intensity Focused Ultrasound (HIFU) treatment for prostate pathology and who underwent intracavernous injection followed by Color Doppler Duplex Ultrasound (CDDU) at our institution between 2005 and 2019. CDDU findings were recorded following injection of low dose alprostadil (10-20 mcg) and again after a period of privacy and visual sexual stimulation. CCDU findings including peak systolic velocities (PSV), and resistive indices (RIs) were recorded. Arterial insufficiency (AI) was defined as either a post-stimulation PSV &lt; 25 with any RI or a PSV 25-34.9 with RI≥0.9. Cavernous Venous Occlusion Disease (CVOD) was defined as post-stimulation PSV ≥35 with RI &lt; 0.9. Mixed was defined as post-stimulation PSV 25-34.9 with RI &lt; 0.9. Vascular normal was defined as post-stim PSV ≥ 35 with RI ≥ 0.9. Results 380/1917 (19.8%) patients had a past surgical history of prostate surgery. 111/380 (29.2%) underwent RRP, 168/380 (44.2%) patients underwent RALP, 85/380 (22.3%) underwent endourological resection of the prostate and 2/380 (0.5%) patients underwent HIFU. Median age for the RALP group was 60.5 (IQR 23.7-82.8), RRP group was 64.2 (29.7-87.7), endourological resection of the prostate 64.6 (30.8 – 85.6) and HIFU 65.0 (46.9-79.4). 87.1% of patients who had an endoscopic procedure were using phosphodiesterase-5 inhibitors at the time of CDDU. CVOD was the most common etiology of ED in patients who underwent RRP (28.8%) and Endourological procedures of the prostate (32.9%); In patient who underwent RALP the most common etiology of ED was noted to be AI (28.6%), however none of these values were statistically significant (p=0.428). Conclusions There is no difference in etiology of ED in patients who underwent open, robotic or endoscopic manipulation of the prostate as shown by CDDU. Disclosure No

Abstract Introduction Vasectomy is a highly effective, permanent method of contraception. Poor compliance rates have been observed for patients in obtaining their post-vasectomy semen analyses (PVSA). Few studies have looked at associations with low compliance. Objective The objective of our study was to identify compliance rates of post-vasectomy semen analysis and to identify associations that may increase or decrease the rates of compliance. Methods We studied 111 patients between November 2018 and April 2022 who underwent vasectomy at a single institution. Only patients who underwent vasectomy for fertility-related reasons were included in our final analysis. We excluded any patients who had undergone previous vasectomy or vasectomy reversal. Variables analyzed included age, relationship status, presence of primary care provider, anxiety diagnosis, and race. Variables were obtained via chart review which included but was not limited to reviewing notes, summary diagnostic pages, problem lists, and medication lists. All analyses were performed using R version 4.1.2 (R Foundation for Statistical Computing, Vienna, Austria). Categorical data were described with the number and percentage of patients. Continuous data were described with the median, minimum, and maximum. Associations of race and anxiety diagnosis with PVSA were explored using Fisher’s exact test. All p-values were two-sided at the 5% significance level without adjustment for multiple testing. Results Our cohort included 111 men who underwent vasectomy with exclusion of 1 patient who underwent vasectomy for non-fertility reasons. The median age of vasectomy was 38 years (range 26-59 years). Of 110 patients, 83 (75%) returned for PVSA. There were 103 (94%) married patients. Additional cohort characteristics can be seen in Table 1. As shown in Table 2, African American patients were less likely to return for PVSA than either white patients (14% vs. 79%, p&lt;0.001) or Hispanic patients (14% vs. 100%, p=0.015). we did not find evidence of difference between white and Hispanic patients (p=0.58). Patients with an anxiety diagnosis were more likely to undergo PVSA compared to patients without an anxiety diagnosis (p&lt;0.001). Conclusions Patients in our cohort of African American race were significantly less likely to undergo PVSA compared to white and Hispanic patients. This suggests an opportunity for improved counseling in the African American population. We do recognize a disparity in the number of white patients studied (n=95) versus African American (n=7) and Hispanic (n=5) patients. Additionally, patients with an anxiety disorder were more likely to undergo PVSA compared to patients without an anxiety disorder. The prevalence of anxiety disorder in our cohort is somewhat high relative to the overall population in the United States. This could be due to questionnaires used at our institution and the timeliness of those questionnaires. Personality traits could also lead to confounding in anxiety diagnoses. Overall, a 75% rate of PVSA speaks to an opportunity for better counseling regarding PVSA, especially in particular populations such as the African American population. Disclosure No

Abstract Introduction The presence and extent of penile calcifications is an important factor in disease management of Peyronie’s Disease (PD). Calcified plaques may necessitate plaque excision and grafting (E&G) in addition to other therapies or surgeries. PD pathology such as corporal septal involvement, multifocal calcifications, and circumferential corporal calcification can be difficult to assess on color doppler ultrasound (CDDU) due to device limitations. Computed tomography (CT) can be utilized for further characterization of PD. Objective The objective of our study was to review patients who underwent CT imaging for characterization of their Peyronie's Disease. Methods Twenty-three patients with a diagnosis of PD were retrospectively evaluated between 2017 and 2021. Patients underwent CDDU examination with artificial erection and were evaluated based on erectile function, plaque dimension, hourglass deformity, plaque septal involvement, and suspected calcification status. Patients with CDDU examination suggestive of calcification or significant complexity underwent non-contrast CT scan for 3-dimensional evaluation of the plaque prior to surgical discussion. CT complexity was defined as concern for multifocal calcified plaques (&gt;2), partial/complete circumferential corpus cavernosum involvement, or septal involvement. Results All 23 patients had concerning findings on initial examination for calcified plaque which led to their CT evaluation; 9 of 23 (39.1%) patients had exam findings with hourglass deformity. On CT evaluation, calcification was confirmed in 22 of 23 patients (95.7%). Plaque dimensions on CT scan ranged from 0.4 x 0.2 x 0.5 cm to 4.0 x 2.0 x1.7 cm. Many of these measurements were approximations due to circumferential calcified plaque. A classic “gull-wing” appearance was noted in 6 of 23 (26%) patients; 12 of 23 (52.2%) of patients had septal involvement on CT; 8 of 23 patients (34.8%) had significant multifocal disease; 8 of 23 patients (34.8%) decided to proceed with surgical correction via E&G (n = 3), IPP with E&G (n =1), or via IPP with manual remodeling via Wilson technique (n = 4). Conclusions Non-contrast penile CT scan identifies calcification well in patients with Peyronie's Disease. CT allows for increased accuracy of surgical planning especially when evaluating for multifocal disease, circumferential plaque and/or septal involvement. These elements are critical for for providing accurate surgical recommendations and preoperative discussions. Disclosure No
