Quality of life impact and recovery after ureteroscopy and stent insertion: insights from daily surveys in STENTS.

BACKGROUND: Our objective was to describe day-to-day evolution and variations in patient-reported stent-associated symptoms (SAS) in the STudy to Enhance uNderstanding of sTent-associated Symptoms (STENTS), a prospective multicenter observational cohort study, using multiple instruments with conceptual overlap in various domains. METHODS: In a nested cohort of the STENTS study, the initial 40 participants having unilateral ureteroscopy (URS) and stent placement underwent daily assessment of self-reported measures using the Brief Pain Inventory short form, Patient-Reported Outcome Measurement Information System measures for pain severity and pain interference, the Urinary Score of the Ureteral Stent Symptom Questionnaire, and Symptoms of Lower Urinary Tract Dysfunction Research Network Symptom Index. Pain intensity, pain interference, urinary symptoms, and bother were obtained preoperatively, daily until stent removal, and at postoperative day (POD) 30. RESULTS: The median age was 44 years (IQR 29,58), and 53% were female. The size of the dominant stone was 7.5 mm (IQR 5,11), and 50% were located in the kidney. There was consistency among instruments assessing similar concepts. Pain intensity and urinary symptoms increased from baseline to POD 1 with apparent peaks in the first 2 days, remained elevated with stent in situ, and varied widely among individuals. Interference due to pain, and bother due to urinary symptoms, likewise demonstrated high individual variability. CONCLUSIONS: This first study investigating daily SAS allows for a more in-depth look at the lived experience after URS and the impact on quality of life. Different instruments measuring pain intensity, pain interference, and urinary symptoms produced consistent assessments of patients' experiences. The overall daily stability of pain and urinary symptoms after URS was also marked by high patient-level variation, suggesting an opportunity to identify characteristics associated with severe SAS after URS.

Results of the patient report of intermittent catheterization experience (PRICE) study.

AIMS: Patient satisfaction is paramount to health-related quality of life (HR-QoL) outcomes. High quality, quantitative data from the US describing patients' actual experiences, difficulties, and HR-QoL while on an intermittent self-catheterization (ISC) regimen is very scarce. Our objective was to better understand patient practices with and attitudes towards ISC. METHODS: This is a cross-sectional, multi-centered, clinical study of adult men and women performing ISC in the United States. Data collected included demographics, medical history, catheter characteristics, specific self-catheterization habits and two validated HR-QoL questionnaires: The Intermittent Self-Catheterization Questionnaire (ISC-Q) and the Intermittent Catheterization Difficulty Questionnaire (ICDQ). RESULTS: Two hundred participants were recruited from six sites; 70.0% were male, 73.5% were Caucasian with a median age was 51.0 years (range 19-90 years). The ISC-Q showed that the vast majority of participants reported ease with ISC (82.0% satisfaction score) had confidence in their ability to perform ISC (91.9% satisfaction score); yet, many felt self-conscious about doing so (58.3% satisfaction score) and had concerns about long-term adverse effects (58.1% satisfaction score). The ICDQ indicated little to no difficulty for most participants with all routine ISC practices. A small minority of participants reported some difficulty with a "blocking sensation" during initiation of catheterization, leg spasticity, and painful catheterization. Multivariate linear regression results are also reported. DISCUSSION/CONCLUSION: Participants are confident with ISC and have little overall difficulty, which may be a product of successful education and/or catheter design. urinary tract infections (UTIs) were common (yet variable) and may contribute to the noted long-term ISC concerns. Limitations exist including various selection biases leading to concerns of external validity. Future educational interventions in this population may further improve HR-QoL, optimize UTIs prevention, and diminish concerns with long-term ISC.

Health-related quality of life in renal stone formers: are we improving?

PURPOSE OF REVIEW: Health-related quality of life (HRQOL) is a multidimensional construct measuring how disease impacts one's life. In the context of nephrolithiasis this is particularly relevant given the active and quiescent phases of the disease which may not correlate with the traditional index of stone free status. Several instruments are now available to objectively measure HRQOL in this population, including the first disease-specific instrument. Therefore, an overview of emerging data on HRQOL is provided that reviews the availability of these tools/instruments and emphasizes patient-centered care and research. RECENT FINDINGS: The common generic instruments used to measure HRQOL in any population (36-Item Short Form health survey and Patient-Reported Outcomes Measurement Information System) and the only disease-specific instrument developed to measure HRQOL in nephrolithiasis (Wisconsin Stone Quality of Life Questionnaire) are described. Emerging evidence suggests that age and sex influence renal stone formers perception of their HRQOL across a range of dimensions. Several other factors also appear to play a role, such as socioeconomic status, but these have yet to be validated in more than one study or population, and postoperative outcomes measured in terms of HRQOL are almost absent from the literature. SUMMARY: Physician-centric outcomes, such as stone status, are no longer the only objective and acceptable measures by which to understand the natural history of nephrolithiasis. Patient-centered approaches through the use of HRQOL are slowly emerging in research and clinical care alike. However, they remain largely in their infancy in these spheres.

Patient safety education and perceptions of safety culture in American and Canadian urological residency training programs.

INTRODUCTION To assess the perception of patient safety culture and the infrastructure to support patient safety (PS) education within American and Canadian urological residency programs. MATERIALS AND METHODS: A needs assessment was developed by experts in patient safety. The survey contained items about prior PS education, perceived value of learning PS, components of an ideal PS curriculum, and desired resources to facilitate PS education. Select items from the validated AHRQ Survey on Patient Safety Culture (SOPS) were also included. The survey was distributed electronically (12/2018-2/2019) to all urology residents (RES) and program directors (PD) of urological residency programs via the Society of Academic Urologists. All responses were anonymous. RESULTS: A total of 26 PD (18.3%; 26/142) and 100 RES (6.7%; 100/1,491) completed the survey. Nearly all RES received PS training (79%), but this was lower for PD (42%). The majority of RES and PD felt that PS was an important educational competency (RES = 83%; PD = 89%) and a pathway for academic success (RES 74%; PD 84%). Both groups desired an online PS curriculum (RES = 69%; PD = 68%) with error causation models (RES = 42%; PD = 52%) as the primary topic to cover. Assessment of safety culture confirmed safety is a priority, but only 1 PD (5%; 1/19) and 25 RES (25%; 25/100) rated their residency program's overall safety grade as 'excellent'. CONCLUSIONS: PS education remains a priority for program directors and urological trainees. Both groups called for additional resources from urological professional societies for this education. To that end, an online, centralized, freely accessible PS curriculum is under development.

Implementing a patient safety culture survey to identify and target process improvements in academic ambulatory urology practices: a multi-institutional collaborative.

INTRODUCTION: A shared professional culture focused on patient safety is critical to delivering high-quality care. There is a need for objective metrics to help identify target areas for improvement in patient safety culture. The Medical Office Survey on Patient Safety Culture (SOPS) was developed and validated by the United States Agency for Healthcare Research and Quality to measure patient safety culture in the ambulatory setting. In this study we report on safety culture and practices in six academic urology clinics utilizing this validated questionnaire. MATERIALS AND METHODS: The SOPS was administered to all staff in ambulatory urology practices affiliated with participating centers. Percent positive responses were calculated for each of 10 validated composite domains and were compared between sites and respondent roles. Nonparametric statistical analyses were performed to identify differences between groups. RESULTS: The survey was administered to 185 staff members, with an overall response rate of 66%. Within each domain there was substantial variability between sites, with significant differences observed in staff training (p = 0.034), office processes/standardization (p = 0.008), patient care tracking (p = 0.047), communication about errors (p = 0.001), and organizational learning (p = 0.015). Similar variation was seen between respondent roles with significant differences for patient care tracking (p = 0.002) and communication about errors (p = 0.014). CONCLUSIONS: The SOPS is a clinically useful tool to identify issues impacting a practice's safety culture. Substantial variability was observed within each composite domain at the levels of practice site and respondent role. Comparing composite domain results between clinics will allow leadership to identify gaps and evaluate policies and resources of higher performing peer sites.

Individual renal unit urine sampling to identify unilateral metabolic defects
.

AIMS: Preventing kidney stone recurrence relies on detecting and modifying urine chemistry abnormalities. The assumption is that an abnormality is due to a global metabolic defect present in both kidneys. However, we hypothesize that clinically significant unilateral defects may exist. We aimed to identify these patients by sampling urine from each renal unit. MATERIALS AND METHODS: Adults undergoing retrograde upper urinary tract surgery were eligible for inclusion. Excluded were patients with a solitary kidney, suspected urothelial malignancy, or urinary tract infection. Following informed consent, all patients proceeded to the operating room. After induction of anesthesia, cystoscopy with ureteral catheterization was performed with urine collected via gravity drainage for 10 minutes. Urine samples with adequate volume were analyzed for chemistry concentrations. A difference greater than the 75th percentile between matched pairs was considered significant. For urine pH, a difference of 0.5 was considered significant. RESULTS: A total of 47 patients were screened for eligibility with only 13 (28%) electing to enroll in the study (26 renal units). All subjects underwent successful bilateral ureteral catheterization with no adverse events observed or later reported. The mean (± SD) urine volume captured from the right and left renal units was 5.0 ± 7.4 cm3 and 6.6 ± 6.4 cm3, respectively. Urine was only captured from paired renal units in 8 participants (8/13; 62%). Of these 8 participants, 5 (5/8; 63%) had at least 1 unilateral metabolic defect. CONCLUSION: Unilateral renal unit urine sampling is safe and feasible. However, captured urine volumes are small and variable, but chemical analysis can still be performed. Unilateral defects in renal electrolyte handling are relatively common, but the clinical implications of these differences are still yet to be determined.

Kidney stone composition in the Kingdom of Saudi Arabia
.

INTRODUCTION: Urolithiasis is a globally-distributed disease; however, its prevalence varies across countries and regions. Countries in the Middle East have been reported to have particularly high nephrolithiasis prevalence rates. To date, however, we have an incomplete understanding of the composition of stones seen in this region. Therefore, we performed a study to characterize stone composition over a 14-year period in the Eastern Province of the Kingdom of Saudi Arabia (KSA). MATERIALS AND METHODS: A retrospective review of all adult patients who had the composition of their upper urinary tract calculi analyzed at Johns Hopkins Aramco Healthcare (JHAH) between 1999 and 2013 was performed. Patient demographics and pathology results were obtained from the electronic medical record. RESULTS: A total of 1,747 stones were analyzed in the study period. The results are presented in the Table. Male patients predominated (79%). For both men and women, the majority of stones were calcium oxalate: 85.2% male, 85.9% female. Uric acid stones were the next most common: 10.1% male; 9.0% female. Overall, there were no significant differences between gender with regards to the distribution of stone types. CONCLUSION: This study represents one of the largest characterizations of stone composition in the Middle East. There remains a significant gender disparity in stone prevalence in the Eastern Province of KSA, with males affected to a significantly greater extent. Calcium oxalate is the most common type of stone, and this is true for both men and women. Future investigations of dietary and environmental factors can build on these initial epidemiologic findings.

Minimally Invasive ("Mini") Percutaneous Nephrolithotomy: Classification, Indications, and Outcomes.

Minimally invasive endoscopic procedures are often employed for the surgical removal of kidney stones. Traditionally, large stones are removed by (standard) percutaneous nephrolithotomy (SPCNL). Although effective for the clearance of large stone burdens, SPCNL is associated with significant morbidity. Therefore, in an effort to reduce this morbidity, while preserving efficacy, mini-PCNL (MPCNL) with a smaller tract size (<20 French) was developed. Several studies suggest that MPCNL has a comparable stone-free rate to SPCNL. However, the question of lower morbidity with MPCNL remains unanswered. In this review, we describe the equipment, indications, and efficacy of MPCNL with particular attention to its value over traditional minimally invasive stone removal techniques.

Challenging Case: Stones.

A 40-year-old woman presents to the emergency department after a motor vehicle accident, and a CT scan revealed no injuries but incidentally notes three non-obstructing stones in the left kidney of 3, 4, and 5 mm in size. She is completely asymptomatic and has no history of urolithiasis.

Care of acute renal colic: a survey of emergency medicine physicians.

INTRODUCTION: To determine the contemporary practice patterns of academic emergency department (ED) providers in the United States for an episode of acute renal colic. MATERIALS AND METHODS: A 30-question survey was developed to assess ED providers' clinical decision making for an index patient with acute renal colic. The survey population was all attending and resident physicians affiliated with an American emergency medicine residency program with an institutional profile available on the Society for Academic Emergency Medicine (156 programs; 95% of programs in the United States). The survey was conducted in October 2014. A response rate of 8.1% (289/3563) was achieved, which represented 29% (46/156) of the programs. RESULTS: Only 17% (53/289) of respondents were aware of the American Urological Association (AUA) guidelines on the management and imaging of ureteral calculi. A clinical care pathway was uncommon amongst institutions (6/46; 13%), but desired by providers (193/289; 67%). A low dose non-contrast computed tomography (CT) would be the most preferred initial diagnostic imaging modality (139/289; 48%). Initial imaging choice was not influenced by respondent role, program, census region, practice environment, ED size, ED volume, presence of a clinical care pathway, or knowledge of the AUA guidelines (all p > 0.05). CONCLUSIONS: In this cross-sectional survey of academic emergency medicine providers, we demonstrated a lack of awareness of quality initiatives and uncommon use of clinical care pathways. We observed that diagnostic imaging modalities with reduced radiation were commonly preferred, and that imaging preference was not associated with several demographic or institutional characteristics.

Patient and institutional characteristics associated with initial computerized tomography in children presenting to the emergency department with kidney stones.

PURPOSE: Professional associations recommend ultrasound as the initial imaging study in children with suspected nephrolithiasis but computerized tomography remains frequently used. We identified patient and institutional characteristics associated with computerized tomography as the first imaging study in children with nephrolithiasis diagnosed in the emergency department. MATERIALS AND METHODS: We performed a cross-sectional study of children 2 to 18 years old with nephrolithiasis who were referred to a freestanding pediatric hospital from 2003 to 2012. We identified the imaging modality first used to evaluate the child. Medical directors at the emergency department where children were first evaluated were sent a questionnaire to ascertain emergency department characteristics. Multivariate hierarchical logistic regression models were used to determine patient and institutional characteristics associated with initial computerized tomography. RESULTS: Of 536 eligible children 323 (60.2%) were evaluated at emergency departments from which surveys were returned. Of the 323 children 238 (71%) underwent computerized tomography as initial imaging. Ultrasound was available at all emergency departments. Older patient age was associated with higher initial computerized tomography use (OR 1.09, 95% CI 1.04-1.16). A more recent year of diagnosis (OR 0.80, 95% CI 0.72-0.88) and a clinical care pathway that used ultrasound as initial imaging (OR 0.29, 95% CI 0.01-0.38) were associated with lower initial computerized tomography use. CONCLUSIONS: A clinical care pathway in the emergency department was the only institutional characteristic associated with lower computerized tomography use. Future studies are needed to determine whether care pathways using ultrasound for initial imaging in children with suspected nephrolithiasis would decrease inappropriate computerized tomography and improve adherence to national guidelines.

Guideline of guidelines: kidney stones.

Several professional organizations have developed evidence-based guidelines for the initial evaluation, diagnostic imaging selection, symptomatic management, surgical treatment, medical therapy, and prevention of recurrence for both ureteric and renal stones. The purpose of this article is to summarize these guidelines with reference to the strength of evidence. All guidelines endorse an initial evaluation to exclude concomitant infection, imaging with a non-contrast computed tomography scan, and consideration of medical expulsive therapy or surgical intervention depending on stone size and location. Recommends for metabolic evaluation vary by guideline, but all endorse increasing fluid intake to reduce the risk of recurrence.

Postoperative Recovery of Quality-of-Life Following Ureteroscopy for Nephrolithiasis: The Impact on Pain Intensity and Interference and the Ability to Participate in Social Roles.

OBJECTIVE: To prospectively capture patient-reported outcomes to assess the recovery profile of ureteroscopy (URS). MATERIALS AND METHODS: Adults undergoing URS for renal/ureteral stones were eligible for inclusion (11/2020-8/2022). Patients prospectively completed PROMIS - Pain Intensity, - Pain Interference, and - Ability to participate in social roles and activities in-person preoperatively (POD 0) and via email on POD 1, 7, 14, and 30. Scores are reported as T-scores (normalized to U.S. population, mean=50) with a change of 5 (0.5 SD) considered clinically significant. RESULTS: One hundred and seventy-eight participants enrolled at POD 0 (POD 1 =87, POD 7 =83, POD 14 =70, POD30 =67). There was a worsening of quality of life from day 0 to day 1 and day 0 to 7. All dimensions then improved with an increase in scores from day 0 to day 14 and day 0 to day 30. On multivariable analysis, the presence of a preoperative ureteral stent (OR 0.14) and use of semirigid URS (OR 0.33) were associated with a reduced odds for severe pain interference at day 1. The use of semirigid URS (OR 0.20) was associated with a reduced odds for severe worsening in the ability to participate in social roles at day 1. CONCLUSION: Ability to participate in social roles declines immediately postoperatively, while pain intensity and interference sharply increase. There is a gradual improvement until POD 30. Findings suggest preoperative stents may influence postoperative recovery. Results offer meaningful insight to assist in counseling and setting expectation for patients postoperatively.

Vulnerability to Financial Toxicity From Stone Surgery.

PURPOSE: Financial toxicity has been described in stone formers however little is understood regarding its causes and how it may relate to stone surgery. We therefore aimed to longitudinally describe markers of financial strain in stone formers from the preoperative to postoperative time points. MATERIALS AND METHODS: A prospective cohort study was conducted from January 2022 to April 2023. Patients were enrolled in the waiting area prior to undergoing elective ureteroscopy or percutaneous nephrolithotomy. Participants completed the Commonwealth Fund's Biennial Health Insurance Survey at this time point and at 30 days postop. Items were pre-selected from the survey to capture markers of financial strain due to healthcare costs. RESULTS: One hundred nine participants were enrolled. Participants were a majority white (70%), college educated (62%), and privately ensured (72%). Despite these traditionally protective sociodemographic features, 42% of patients reported some marker of financial strain at the preoperative timepoint. Patients with Medicaid reported even higher financial stress (67%). Furthermore, 46% of patients did not know their deductible amount. Response rate was low at 30 days postop (35%) but suggested some patients were experiencing new financial strains. CONCLUSIONS: This paper shows that a significant proportion of stone patients are already displaying markers of financial strain from healthcare bills even prior to surgery as well as poor understanding of the costs they may incur. This makes them vulnerable to experiencing financial toxicity postoperatively and emphasizes the importance of understanding all contributing factors when developing future strategies to intervene in financial toxicity.

Proactive Patient Safety: Focusing on What Goes Right in the Perioperative Environment.

OBJECTIVE: Adverse events in the perioperative environment, a potential risk to patients, may be mitigated by nurturing staff adaptability and resiliency. An activity called "One Safe Act" (OSA) was developed to capture and highlight proactive safety behaviors that staff use in their daily practice to promote safe patient care. METHODS: One Safe Act is conducted in-person in the perioperative environment by a facilitator. The facilitator gathers an ad hoc group of perioperative staff in the work unit. The activity is run as follows: staff introductions, purpose/instructions of the activity, participants self-reflect about their OSA (proactive safety behavior) and record it as free text in an online survey tool, the group debriefs with each person sharing their OSA, and the activity is concluded by summarizing behavioral themes. Each participant completed an attitudinal assessment to understand changes in safety culture perception. RESULTS: From December 2020 to July 2021, a total of 140 perioperative staff participated (21%, 140/657) over 28 OSA sessions with 136 (97%, 140/136) completing the attitudinal assessment. A total of 82% (112/136), 88% (120/136), and 90% (122/136) agreed that this activity would change their practices related to patient safety, improve their work unit's ability to deliver safe care, and demonstrated their colleagues' commitment to patient safety, respectively. CONCLUSIONS: The OSA activity is participatory and collaborative to build shared, new knowledge, and community practices focused on proactive safety behaviors. The OSA activity achieved this goal with a near universal acceptance of the activity in promoting an intent to change personal practice and increasing engagement and commitment to safety culture.

The Endourological Society Inaugural Census Report.

The Endourological Society, the premier urologic society encompassing endourology, robotics, and focal surgery, is composed of a diverse group of >1300 urologists. However, limited information has been collected about society members. Recognizing this need, a survey was initiated to capture data regarding current member practices, as well as help the Society shape the future direction of the organization. Presented herein is the inaugural Endourological Society census report as the beginning of a continued effort for global improvement in the field of endourology. Using a REDCap® database, an email survey was circulated to the membership of the Endourological Society from May through June 2021. Twenty questions were posed, categorizing member data in terms of epidemiology/demographics, practice patterns, member opinions, and future educational preferences. Responses were received from 534 members, representing 40.3% of membership. Data demonstrated that the average age, gender, race, and ethnicity of the typical Society member respondent is a 48-year-old Caucasian male working in the United States, with a mean of 25 years in practice. Retrograde endoscopy and percutaneous nephrolithotomy were identified as the most common practice skills, and 50% of members are involved in robotics. Importantly, the census confirmed that the World Congress of Endourology and Technology remains popular with Society members as a means of educational advancement. To sustain and advance the Society, information is required to understand the career interests and future educational desires of its members. This inaugural census provides crucial data regarding its membership and how the Society can achieve continued success and adjust its focus. Future census efforts will expand on the initial findings and stratify the data to elucidate changes in the needs of the Society as a whole. Circulating an annual census will allow for continued improvements in the field of endourology and, ultimately, better care for urologic patients.

Clinicians' Perspectives on Proactive Patient Safety Behaviors in the Perioperative Environment.

Importance: The perioperative environment is hazardous, but patients remain safe with a successful outcome during their care due to staff adaptability and resiliency. The behaviors that support this adaptability and resilience have yet to be defined or analyzed. One Safe Act (OSA), a tool and activity developed to capture self-reported proactive safety behaviors that staff use in their daily practice to promote individual and team-based safe patient care, may allow for improved definition and analysis of these behaviors. Objective: To thematically analyze staff behaviors using OSA to understand what may serve as the basis for proactive safety in the perioperative environment. Design, Setting, and Participants: This qualitative thematic analysis included a convenience sample of perioperative staff at a single-center, tertiary care academic medical center who participated in an OSA activity during a 6-month period in 2021. All perioperative staff were eligible for inclusion. A combined deductive approach, based on a human factor analysis and classification framework, as well as an inductive approach was used to develop themes and analyze the self-reported staff safety behaviors. Exposures: Those selected to participate were asked to join an OSA activity, which was conducted in-person by a facilitator. Participants were to self-reflect about their OSA (proactive safety behavior) and record their experience as free text in an online survey tool. Main Outcome and Measures: The primary outcome was the development and application of a set of themes to describe proactive safety behaviors in the perioperative environment. Results: A total of 140 participants (33 nurses [23.6%] and 18 trainee physicians [12.9%]), which represented 21.3% of the 657 total perioperative department full-time staff, described 147 behaviors. A total of 8 non-mutually exclusive themes emerged with the following categories and frequency of behaviors: (1) routine-based adaptations (46 responses [31%]); (2) resource availability and assessment adaptations (31 responses [21%]); (3) communication and coordination adaptation (23 responses [16%]); (4) environmental ergonomics adaptation (17 responses [12%]); (5) situational awareness adaptation (12 responses [8%]); (6) personal or team readiness adaptation (8 responses [5%]); (7) education adaptation (5 responses [3%]); and (8) social awareness adaptation (5 responses [3%]). Conclusions and Relevance: The OSA activity elicited and captured proactive safety behaviors performed by staff. A set of behavioral themes were identified that may serve as the basis for individual practices of resilience and adaptability that promote patient safety.

Longitudinal Changes in Quality of Life After Ureteroscopy for Nephrolithiasis.

OBJECTIVE: To assess alterations in health-related quality of life (HRQOL) in patients with nephrolithiasis, given the limited prospective data on patient reported outcomes following surgical intervention with ureteroscopy. METHODS: Adults with either a renal or ureteral calculus who underwent ureteroscopy (URS) were recruited prospectively from 2017-2020. Participants completed the PROMIS-29 profile which measures the dimensions of physical function, fatigue, pain interference, depressive symptoms, anxiety, ability to participate in social roles and activities, and sleep disturbance at enrollment, 1-, 6-, and 12-months. Scores are reported as T-scores (normalized to US-population) and were compared at each time point against the mean for the US-population (50) using one-sample Welch's t'test and between each pairwise time point comparison using a Wilcoxon signed rank test. RESULTS: At enrollment, a total of 69 participants completed the PROMIS-29 survey. As compared to the US-population mean, participants at enrollment had significantly different scores in physical function, fatigue, pain interference, depressive symptoms, anxiety, and sleep disturbance (all P<.05), but not ability to participate in social roles and activities. In pairwise comparisons, improvement was only observed from enrollment to 1-month in pain interference (P<.01) and fatigue (P = .03). However, there was improvement at a longer interval from enrollment to 12-months in all dimensions (pairwise comparisons, all P<.05) except depressive symptoms. CONCLUSION: The PROMIS-29 profile is responsive to changes in HRQOL for patients with nephrolithiasis undergoing URS, with improvement of PROMIS scores up to 12-months. This information can be utilized for patient counseling to guide expectations during the recovery period.

Heterogeneity in stone culture protocols and endourologist practice patterns: a multi-institutional survey.

Kidney stone cultures can be beneficial in identifying bacteria not detected in urine, yet how stone cultures are performed among endourologists, under what conditions, and by what laboratory methods remain largely unknown. Stone cultures are not addressed by current clinical guidelines. A comprehensive REDCap electronic survey sought responses from directed (n = 20) and listserv elicited (n = 108) endourologists specializing in kidney stone disease. Questions included which clinical scenarios prompt a stone culture order, how results influence post-operative antibiotics, and what microbiology lab protocols exist at each institution with respect to processing and resulting stone cultures. Logistic regression statistical analysis determined what factors were associated with performing stone cultures. Of 128 unique responses, 11% identified as female and the mean years of practicing was 16 (range 1-46). A specific 'stone culture' order was available to only 50% (64/128) of those surveyed, while 32% (41/128) reported culturing stone by placing a urine culture order. The duration of antibiotics given for a positive stone culture varied, with 4-7 days (46%) and 8-14 days (21%) the most reported. More years in practice was associated with fewer stone cultures ordered, while higher annual volume of percutaneous nephrolithotomy was associated with ordering more stone cultures (p < 0.01). Endourologists have differing practice patterns with respect to ordering stone cultures and utilizing the results to guide post-operative antibiotics. With inconsistent microbiology lab stone culture protocols across multiple institutions, more uniform processing is needed for future studies to assess the clinical benefit of stone cultures and direct future guidelines.
