ABSTRACT Objectives Lasers are integral to contemporary endourologic stone surgery; however, reported institutional practices regarding laser access, personnel requirements, and safety protocols vary. We sought to characterize respondent‐reported laser access models, operational requirements, safety practices, and perceived barriers to care. Materials and Methods A cross‐sectional, web‐based 25‐item survey was distributed between October 2024 and March 2025 through social media, professional organizations, and departmental contacts. The survey assessed practice characteristics, laser access, physician and technician responsibilities, institutional safety requirements, and perceived barriers to care. Responses were self‐reported, collected anonymously, and summarized using descriptive statistics. Results A total of 187 respondents completed the survey; 85.6% identified as endourologists and 61.5% practiced in academic settings. Most respondents reported institution‐owned laser equipment (70.1%), while 9.6% reported contracted equipment and 20.3% combination models. Among respondents addressing contracted equipment availability ( n = 58), 55.2% reported ready access after regular business hours and 46.6% on weekends. Among 182 evaluable responses, 65.4% reported that physicians could operate lasers without a technician present. Fifty‐two respondents perceived that technician availability could affect patient care; among these, 40 reported potential delays in definitive treatment and 33 reported potential multiple or staged procedures. Staff laser safety goggles could be deferred according to 78.4% of evaluable responses, and 18.3% reported a prior institutional laser safety incident. Conclusion This survey identified substantial respondent‐reported variation in laser access, staffing requirements, and safety practices. The findings describe perceived institutional practices and barriers and do not establish effects on treatment delays, workflow efficiency, patient outcomes, or comparative safety. Future studies should directly compare institutional models using objective measures of access, workflow, treatment delays, and safety outcomes.

Objective To assess the effect of Moses™ 2.0 (Lumenis Be Ltd., Yokneam Illit, Israel; Boston Scientific, Marlborough, MA, USA) for lithotripsy of renal stones of 8–20 mm in diameter on operative time, surgeon workload, and retropulsion. Subjects/Patients and Methods In our multicentre, randomised, double‐blind clinical trial, patients were randomised 1:1 to standard or Moses 2.0 laser lithotripsy and stratified by stone size. Patients and surgeons were blinded to laser modality. Primary outcomes were total operative time as well as surgeon workload assessed by the National Aeronautics and Space Administration‐Task Load Index (NASA‐TLX). Secondary outcomes were stone retropulsion evaluated by blinded video review and postoperative clinical outcomes. Linear regression modelling was used for analysis. Results A total of 153 patients (79 Standard, 74 Moses 2.0) with similar clinical, stone, and operative characteristics were evaluated. There was no significant difference in operative times between the Standard and Moses 2.0 groups ( P = 0.73). Moses 2.0 was associated with lower effort, frustration, mental, physical, and temporal workload, as well as higher rated overall performance compared to the standard laser. Video review demonstrated no difference in rates of retropulsion ( P = 0.13). Complication rates (Standard: 13%; Moses 2.0: 10%) and stone‐free rates (Standard: 51%; Moses: 2.0 55%) were comparable. Conclusion Our study evaluated the impact of Moses 2.0 technology on high‐powered renal stone dusting, constituting the largest double‐blind trial of its kind to date. There was insufficient evidence to suggest any difference in operative times or clinical outcomes when using Moses 2.0 compared to standard laser lithotripsy. Moses 2.0 was associated with reduced surgeon workload, which has implicit impact on surgeon wellness.

Abstract Purpose The temporarily implanted nitinol device (TIND) is a minimally invasive surgical technique (MIST) for benign prostatic hyperplasia (BPH) that promises fewer unwanted side effects compared with traditional bladder outlet procedures for small glands with high-riding bladder necks, including transurethral incision of the prostate (TUIP). This study sought to compare the effect of TIND vs. TUIP on ejaculatory function in sexually active males using the Male Sexual Health Questionnaire Ejaculatory Function Short Form (MSHQ-EjD-SF). Methods A retrospective review of a prospectively maintained database of all patients who underwent TIND at our institution between 1/1/2022 and 10/1/2024. Patients were excluded if they reported no postoperative ejaculations. Patients who underwent TUIP during the same period were compared. Age, prostate volume, PSA, and urinary parameters were collected. MSHQ-EjD-SF scores were collected for all patients. Continuous variables were compared using Wilcoxon Rank sum test and categorical variables using Fisher’s exact test. Results A total of 27 patients underwent TIND, of which 17 reported postoperative ejaculations and were compared with 17 patients who underwent TUIP during the same period with similar baseline age, prostate volume, and urinary parameters. Median MSHQ-EjD-SF score was higher after TIND compared with TUIP (15.0 (14.0, 15.0) vs. 13.0 (11.0, 13.0), p < 0.01), while bother score was lower (0.0 (0.0, 0.0) vs. 1.0 (0.0, 2.0), p = 0.02). Conclusions Patients experienced negligible effect on ejaculatory function after TIND compared with TUIP. This may be an effective bladder outlet procedure for patients who prioritize their postoperative ejaculatory function.

Introduction: Adequate bladder distention is critical for safe and efficient transurethral morcellation during endoscopic prostate enucleation. Traditional assessment methods are subjective and may compromise safety and efficiency. We evaluated the feasibility and impact of continuous intravesical pressure (IVP) monitoring using a handheld pressure meter during morcellation compared with conventional manual bladder assessment. Material and Methods: In this prospective, randomized pilot study, 30 patients undergoing transurethral morcellation after bipolar prostate enucleation were randomized 1:1 to continuous IVP monitoring with a handheld pressure meter (Group A) or manual suprapubic bladder assessment by a urology fellow (Group B). In Group A, morcellation was performed while IVP remained within a predefined safe range (15–60 mmHg), with pauses for pressure correction as needed. The primary outcome was the number of morcellation pauses. Secondary outcomes included morcellation time, morcellation efficiency (g/min), total operative time, hemoglobin deficit, complications, and functional outcomes (International Prostate Symptom Score, maximum urinary flow rate, and post-void residual) at 3 and 6 months. Results: Baseline characteristics were comparable between groups. Morcellation time was significantly shorter in Group A (8.9 ± 3.7 vs 13.3 ± 2.1 minutes; p = 0.0008), with fewer morcellation pauses (3.3 ± 0.7 vs 5.7 ± 1.2; p < 0.0001) and higher morcellation efficiency (9.9 ± 2.0 vs 5.9 ± 0.6 g/min; p < 0.0001). Enucleation time, total operative time, tissue weight, and hemoglobin deficit were similar. No bladder injuries or postoperative fever occurred. Functional outcomes at 3 and 6 months were comparable. Conclusion: Continuous IVP monitoring using a handheld pressure meter during transurethral morcellation is feasible, reduces interruptions, and significantly improves morcellation efficiency without compromising safety or functional outcomes. This inexpensive technique may be a valuable safety adjunct, particularly for less experienced surgeons, and merits evaluation in larger randomized trials.

Background: Sinonasal malignancies (SNM) are rare cancers associated with poor prognosis and impaired quality of life (QOL). The 22-question Sino-Nasal Outcome Test (SNOT-22) has been used to assess QOL in patients with SNM. Objective: To determine the minimal clinically important difference (MCID) for the SNOT-22 in patients with SNM. Methods: About 264 patients with SNM were drawn from a prospective, longitudinal, multi-institutional study. SNOT-22 scores were collected at pre-treatment baseline and follow-up through 5 years post-treatment. Cronbach’s alpha was used to assess the internal consistency of the SNOT-22. Distribution-based approaches were used to estimate the MCID. Multivariable regression identified factors associated with SNOT-22 improvement exceeding the determined MCID. Results: Cronbach’s alpha was >.85. The estimated MCIDs were: 1.44 (Cohen’s effect size), 1.32 (standard error of the mean), 10.45 (1/2 of baseline standard deviation), and 3.67 (minimum detectable change). The mean MCID across methods was 4.22. Multivariable regression demonstrated higher odds of clinically meaningful improvement from baseline in patients with early-stage disease (odds ratio (OR) 3.510, P = .035), no neck irradiation (OR 11.050, P = .014), and neoadjuvant therapy (OR 16.667, P = .047). Conclusions: The SNOT-22 MCID was estimated as 4.22 in a large multi-center cohort of patients with SNM, suggesting that relatively small QOL changes are clinically relevant. When applying the MCID to the current cohort, advanced stage, treatment of neck disease, and not requiring neoadjuvant therapy were predictive of worse QOL.

Introduction: Ureteroscopy (URS) is the most commonly performed surgery for the management of renal stones. Post-URS sepsis has been reported to be around 5%, but most studies rely on purchased datasets or electronic medical record (EMR) data that pull data based on billing codes of sepsis without clinical verifications. This study aims to evaluate the true incidence of sepsis using the Sepsis-3 criteria at a single tertiary care institution. Methods: A retrospective review was conducted on all URS procedures at a single tertiary care institution from 2021 to 2022, including both Medicare and private insurance patients ≥18 years old. The EMR was queried for URS procedure codes and readmission within 30 days post-procedure with a sepsis diagnosis code. All other procedures, including URS during percutaneous nephrolithotomy, were excluded. Each identified case was evaluated for sepsis using the Sepsis-3 criteria, including sequential organ failure assessment (SOFA) and quick SOFA (qSOFA). Results: A total of 1316 patients underwent URS. Nineteen patients were identified with a sepsis diagnosis, giving an initial post-URS sepsis rate of 1.44%. After EMR verification, 5 patients were excluded, leaving 14 (1.06%) patients with a diagnosis code of sepsis. Using Sepsis-3 criteria, only 6 (0.44%) met the diagnosis. Conclusions: This retrospective review identified only 0.44% of patients with a true post-URS sepsis within 30 days using Sepsis-3 criteria. The difference in our rate from the initial query and current literature highlights the need for accurate clinical diagnosis and documentation of sepsis.

Background: Breast cancer polygenic risk scores (PRS) and traditional risk models (e.g., the Gail model [Gail]) are known to contribute largely independent information, but it is unclear how the overlap varies by ancestry, age, disease type (invasive breast cancer, DCIS), and risk threshold. Methods: In a retrospective case–control study, we evaluated risk prediction performance in 180,398 women (161,849 of European ancestry; 18,549 of Asian ancestry). Odds ratios (ORs) from logistic regression models and the area under the receiver operating characteristic curve (AUC) were estimated. Results: PRS for invasive disease showed a stronger association in younger (<50 years) women (OR = 2.51, AUC = 0.622) than in women ≥ 50 years (OR = 2.06, AUC = 0.653) of European ancestry. PRS performance in Asians was lower (OR range = 1.62–1.64, AUC = 0.551–0.600). Gail performance was modest across groups and poor in younger Asian women (OR = 0.94–0.99, AUC = 0.523–0.533). Age interactions were observed for both PRS (p < 0.001) and Gail (p < 0.001) in Europeans, whereas in Asians, age interaction was observed only for Gail (invasive: p < 0.001; DCIS: p = 0.002). PRS identified more high-risk individuals than Gail in Asian populations, especially ≥50 years, while Gail identified more in Europeans. Overlap between PRS, Gail, and family history was limited at higher thresholds. Calibration analysis, comparing empirical and model-based ROC curves, showed divergence for both PRS and Gail (p < 0.001), which indicates miscalibration. In Europeans, family history and prior biopsies drove Gail discrimination. In younger Asians, age at first live birth was influential. Conclusions: PRS adds value to risk stratification beyond traditional tools, especially in younger women and Asian ancestry populations.

Purpose: To compare stone clearance, stone-free status, and complications between patients undergoing ureteroscopy for renal stones using either Flexible and Navigable Ureteral Access Sheath (FANS) or the CVAC 2.0 system. Materials and Methods: A prospective study was completed on patients undergoing flexible ureteroscopy for renal stones at a single institution from March 2024 to December 2024. Subject demographics, intra-op data, volumetric and single-dimension stone clearance on non-contrast CT, and complications were compared. Stone-free rates (SFRs) using standardized cutoffs were compared. Pearson correlation analysis was performed to assess the relationship between preoperative stone volume and postoperative stone burden. Subanalysis was performed for patients with preoperative stone burden >1.5 cm. Results: A total of 123 cases (CVAC 2.0-36, FANS-87) were included, with 64 eligible for volumetric analysis. Preoperative stone volume was larger in the CVAC group vs FANS (1075 mm 3 vs 397 mm 3 ; p < 0.001). Absolute stone clearance was greater in the CVAC group (1016 mm 3 vs 392 mm 3 ; p < 0.001), whereas residual stone volume (4.1 mm 3 vs 15.0 mm 3 ; p = 0.55) and SFRs (90% vs 81%; p = 0.48) were similar. In individuals with >1.5 cm preoperative stone burden, relative stone clearance was greater with CVAC 2.0 (98.9% vs 95.1%; p = 0.026). Pearson correlation analysis revealed positive linear relationship between preoperative stone volume and residual stone volume for FANS, but not for CVAC 2.0. Conclusions: In this comparative study of FANS and CVAC 2.0, over 95% stone clearance was observed in both groups despite large initial stone burdens. In contrast to FANS, residual stone volumes with CVAC 2.0 did not increase significantly with increasing preoperative stone volumes.
