Homogeneity of cognitive and behavioural processes underlying the relationship between insomnia and body image disturbance.

Specific cognitive behavioural mechanisms related to selective attention, situational avoidance and physical appearance are implicated in the development and maintenance of insomnia and negative reinforcement of body image disturbances. Therefore, we examined whether these processes potentially mediate the relationship between insomnia and body image perception. N = 728 participants completed self-reported measures of sleep-associated monitoring, insomnia symptoms, body image disturbance and coping with body image challenges. Symptoms of insomnia and sleep-associated monitoring behaviour were independently related to increased reports of body image disturbance, cognitive distortions of body image, appearance fixing (i.e. altering appearance by covering, camouflaging or correcting the perceived defect), avoidance (i.e. attempt to escape or avert stressful body image situations) and reduced levels of positive rationale acceptance (i.e. acceptance of the challenging event and positive self-care or rationale self-talk about one's appearance). More crucially, sleep-related monitoring on awakening, cognitive distortion of body image and negative coping strategies related to body image (i.e. appearance fixing, avoidance, rationale acceptance) mediated the relationship between reports of body image disturbance and insomnia symptoms. The current findings expand upon previous research demonstrating consistent relationships between poor sleep and increased dissatisfaction with cutaneous features, by providing novel evidence that body image disturbances are associated with symptoms of insomnia. More crucially, we highlight the role of particular cognitive and behavioural mechanisms pertaining to sleep (i.e. selective attention for physical signs of poor sleep) and body image (i.e. avoidance and rationale acceptance) which may be targeted as part of cognitive behavioural treatments.

Is a Good Quality of Life and Health Status Possible in Older Patients Dying from Critical Limb-Threatening Ischemia: A Prospective Clinical Study.

BACKGROUND: Revascularization is the cornerstone in the treatment of patients with critical limb-threatening ischemia (CLTI). However, the 2-year mortality rate is up to 50% in these patients. Therefore, the clinical benefit of revascularization needs to be considered carefully. The question emerges if there are changes in quality of life (QoL) and health status (HS) in the end-of-life phase of CLTI in older patients. METHODS: Patients with CLTI and of an age of 70 years or older were included in a prospective observational cohort study. Treatment consisted of endovascular revascularization, surgical revascularization, or conservative therapy. The follow-up period was 2 years. Within this follow-up period, patients completed the following questionnaires at six specified time intervals: the WHOQOL-BREF and the SF-12. Patients who died within 2 years after inclusion were analyzed. Final scores were defined as the last measurement at end of follow-up or death. RESULTS: Eighty two patients (42.1%) died during the 24-month follow-up. QoL and HS before death did not decrease with treatment (option: endovascular intervention, surgical revascularization, or conservative therapy). CONCLUSIONS: Older patients with CLTI and a life expectancy less than 2 years had no differences in QoL and HS before death compared to their previous measurement. Except for the mental HS domain, no differences in the percentage of patients showing significant individual change in QoL and HS were found between the treatments. For clinicians, it is important to use patient-reported outcome measure when discussing treatment for older frail patients with CLTI in a shared decision-making process.

Psychiatric Diagnoses and Other Factors Associated with Emergency Department Return within 30 Days of Ureteroscopy.

PURPOSE: Emergency department visits after ureteroscopy are costly and inconvenient. To better understand those at risk we aimed to identify patient demographic, medical and surgical factors associated with 30-day emergency department presentation following ureteroscopy for urolithiasis with particular attention to those with a history of a psychiatric diagnosis. MATERIALS AND METHODS: We retrospectively reviewed 1,576 cases (1,395 adults) who underwent stone related ureteroscopy during 3 years at a total of 2 hospitals. We collected patient demographics, medical history and operative details. The primary outcome was return to the emergency department within 30 days of ureteroscopy. Logistic regression was performed to examine factors associated with emergency department presentation. RESULTS: Of the patients 613 (43.9%) had a history of psychiatric diagnosis. Of those with ureteroscopy encounters 12.6% returned to the emergency department within 30 days of ureteroscopy, including 58.8% with a history of psychiatric diagnosis. On multivariable analysis variables associated with emergency department return included a history of psychiatric diagnosis (OR 1.57, p = 0.012), uninsured status (OR 2.46, p = 0.001) and a stone only in the kidney (OR 1.76, p = 0.022). Patients who returned to the emergency department had had more emergency department visits in the year prior to surgery (OR 1.40, p <0.001). On univariable analysis older patients and those with longer operative time were more frequently admitted from the emergency department (OR 1.03, p = 0.002 and OR 1.96, p = 0.03. respectively) while uninsured patients were admitted less frequently (OR 0.19, p = 0.013). No difference was noted in admissions between those with a psychiatric diagnosis and all others (60.7% vs 55.8%, p = 0.48). CONCLUSIONS: We identified factors associated with emergency department return after ureteroscopy, including a history of psychiatric diagnosis, uninsured status and emergency department visits in the year before surgery. These patients may benefit from targeted interventions to help avoid unnecessary emergency department visits.

Cost-effectiveness of the treatments for critical limb ischemia in the elderly population.

OBJECTIVE: The treatment of critical limb ischemia (CLI), with the intention to prevent limb loss, is often an intensive and expensive therapy. The aim of this study was to examine the cost-effectiveness of endovascular and conservative treatment of elderly CLI patients unsuitable for surgery. METHODS: In this prospective observational cohort study, data were gathered in two Dutch peripheral hospitals. CLI patients aged 70 years or older were included in the outpatient clinic. Exclusion criteria were malignant disease, lack of language skills, and cognitive impairment; 195 patients were included and 192 patients were excluded. After a multidisciplinary vascular conference, patients were divided into three treatment groups (endovascular revascularization, surgical revascularization, or conservative therapy). Subanalyses based on age were made (70-79 years and ≥80 years). The follow-up period was 2 years. Cost-effectiveness of endovascular and conservative treatment was quantified using incremental cost-effectiveness ratios (ICERs) in euros per quality-adjusted life-years (QALYs). RESULTS: At baseline, patients allocated to surgical revascularization had better health states, but the health states of endovascular revascularization and conservative therapy patients were comparable. With an ICER of €38,247.41/QALY (∼$50,869/QALY), endovascular revascularization was cost-effective compared with conservative therapy. This is favorable compared with the Dutch applicable threshold of €80,000/QALY (∼$106,400/QALY). The subanalyses also established that endovascular revascularization is a cost-effective alternative for conservative treatment both in patients aged 70 to 79 years (ICER €29,898.36/QALY; ∼$39,765/QALY) and in octogenarians (ICER €56,810.14/QALY; ∼$75,557/QALY). CONCLUSIONS: Our study has shown that endovascular revascularization is cost-effective compared with conservative treatment of CLI patients older than 70 years and also in octogenarians. Given the small absolute differences in costs and effects, physicians should also consider individual circumstances that can alter the outcome of the intervention. Cost-effectiveness remains one of the aspects to take into consideration in making a clinical decision.

Quality of Life and not Health Status Improves After Major Amputation in the Elderly Critical Limb Ischaemia Patient.

OBJECTIVES: A patient-oriented appraisal of treatment has become extremely important, particularly in elderly patients with critical limb ischaemia (CLI). Quality of life (QoL) is an important patient-reported outcome in vascular surgery. Frequently, the physical domain of QoL questionnaires represents an 'objective' evaluation of performing activities, which is expected to be impaired after major limb amputation. However, an objective appraisal of physical function is an assessment of health status (HS) and not of QoL. Little is known about the subjective appraisal of physical health (QoL). The goal of this study was to evaluate, prospectively, QoL in relation to HS in elderly CLI patients undergoing major limb amputation. METHODS: Patients suffering from CLI aged 70 years or older were included in a prospective observational cohort study with a follow-up period of 1 year. Patients were divided according to having had an amputation or not. The World Health Organization Quality Of Life-BREF (WHOQOL-BREF) was used to asses QoL. The 12-Item Short Form Health Survey (SF-12) was used to measure HS. These self-reported questionnaires were completed five times during follow-up. RESULTS: Two-hundred patients were included of whom 46 underwent a major limb amputation within one year. Amputees had a statistically significant improvement of their physical QoL after six months (14.0 vs. 9.0 (95% CI -7.84;-1.45),p = 0.005) and after a one-year follow-up (14.0 vs. 9.0 (95% CI -9.58;-1.46),p = 0.008). They did not however show any statistically significant difference in HS. For non-amputees, both physical QoL and HS improved. An instant statistically significant improvement of the physical QoL appeared 1 week after inclusion (12.0 vs. 10.9 (95% CI -1.57;-0.63),p<0.001). Similarly, statistically significant improvement in the physical HS first occurred at 1 week follow-up (29.0 vs. 28.9 (95% CI -5.78; -2.23),p = 0.003). CONCLUSIONS: There is a clear difference between patients' functioning (HS) and the patients' appraisal of functioning (QoL). In elderly CLI patients, this study clearly suggests a discrepancy between the physical QoL (WHOQOL-BREF) and HS (SF-12) measurements in vascular amputees. This raises the question, which outcome measurement is the most relevant for elderly CLI patients. Individual treatment goals should be kept in mind when assessing the HS or QoL outcome of patients undergoing hospital care. With respect to shared decision making, distinctive and subjective QoL questionnaires, like the WHOQOL-BREF, provide a very important outcome measurement and should be used in future research.

Is There an Important Role for Anxiety and Depression in the Elderly Patients with Critical Limb Ischemia, Especially After Major Amputation?

BACKGROUND: In patients with critical limb ischemia, an association is assumed between depression and worse outcome for morbidity, such as major limb amputation. After major amputation, anxiety and depression are common. We aimed to determine the association of depressive and anxiety symptoms in the elderly with critical limb ischemia, especially after major limb amputation. METHODS: Patients with critical limb ischemia aged ≥70 years were included in this prospective observational cohort study between January 2012 and February 2016 in 2 Dutch hospitals. After a multidisciplinary vascular conference, patients were divided into 4 treatment groups: endovascular revascularization, surgical revascularization, conservative therapy, and primary major amputation. In a 1-year follow-up period, depression and anxiety were measured 4 times using the Dutch versions of the Center for Epidemiological Studies Depression Scale and the State-Trait Anxiety Inventory. RESULTS: One Hundred eighty-seven patients were included. Within 1 year, 44 patients underwent a major limb amputation. Lower amputation-free survival did not differ significantly for patients with versus without greater anxiety (X2 [1] = 0.689, P = 0.407) and also not for patients with versus without more depressive symptoms (X2 [1] = 0.614, P = 0.433). For both groups, there were no significant changes in anxiety scores over time. After a median follow-up time of 336.5 days and 365 days, depressive symptoms significantly decreased in amputees, respectively, 8.5 vs. 4.5 (95% CI 1.76-7.48, P = 0.002) and 8.5 vs. 4.3 (95% CI 0.61-9.82, P = 0.027) when compared to the baseline measurement. Similarly, nonamputees had significantly lower overall score for depressive symptoms after a median follow-up time of 365 days (10.1 vs. 4.1, 95% CI 4.49 to 6.90, P < 0.001). CONCLUSIONS: In the opinion of the medical health care provider, amputation is a severe and unwanted end phase of critical limb ischemia. However, depressive symptoms seem to decrease over time and anxiety symptoms do not seem to be affected in patients after major limb amputation. In addition, patients with greater trait anxiety or more depressive symptoms at baseline did not have significantly higher amputation rates. These findings are similar to the course of depressive and anxiety symptoms for the elderly patients without major limb amputation.

Purulent Inflatable Penile Prostheses Can Be Safely Immediately Salvaged in Insulin-Dependent Diabetics.

INTRODUCTION: Historically, contra-indications for immediate salvage of an infected penile prosthesis have included purulence on the device, purulent infections in diabetic patients, and severe diabetes. These clinical principles are from the 1990s to early 2000s and based on limited retrospective series or expert opinion. Since the publication of these contra-indications there have been improvements in device design, surgical technique, corporal washout protocols, and perioperative antibiotic prophylaxis that allow us to re-evaluate whether we can broaden the criteria for immediate salvage of an infected penile prosthesis. AIM: To report whether patients with severe diabetes can safely have a purulent inflatable penile prosthesis (IPP) immediately salvaged. METHODS: We considered a "severe diabetic" as a patient whose disease has progressed past diet control and oral medications and, therefore, has insulin-dependent type 2 diabetes mellitus (IDDM II). We retrospectively reviewed 6 consecutive patients with IDDM II and a purulent IPP who had been immediately salvaged from July 2011 to November 2017. In addition to immediate exchange, each received catheter-directed anti-microbial intracorporal irrigation and device culture. All patients were discharged home the next day with oral antibiotics. MAIN OUTCOME MEASURE: Outcomes included repeat penile prosthesis infection or any other complication following immediate salvage. RESULTS: All 6 patients have healed well and remained infection free at their 6- to 8-week post-operative follow-up appointment. 15-39 months after salvage, no patients have had a repeat infection or any other complication. 5 patients received a malleable replacement device and 1 patient was electively converted to an IPP 7 months after his salvage procedure. 1 patient received an IPP during salvage per patient preference. All patients are currently pleased with either their malleable penile prosthesis or IPP. CLINICAL IMPLICATIONS: Immediate salvage attenuates the morbidity associated with an infected penile prosthesis such as irreversible penile shortening and corporal fibrosis. Our findings suggest that more patients than originally thought may be a candidate for immediate salvage. STRENGTH & LIMITATIONS: To our knowledge, this is the first study evaluating outcomes after immediate salvage of a purulent IPP in patients with advanced diabetes. Limitations of the study include the small sample size and retrospective nature. CONCLUSION: Our results suggest that those with IDDM II who have a purulent penile prosthesis may be candidates for safe and effective immediate salvage. Peters CE, Carlos EC, Lentz AC. Purulent Inflatable Penile Prostheses Can Be Safely Immediately Salvaged in Insulin-Dependent Diabetics. J Sex Med 2018;15:1673-1677.

Eating fruits and vegetables. An ethnographic study of American and French family dinners.

The French eat more fruits and vegetables than Americans and have lower rates of childhood obesity. This ethnographic study compares various aspects of meal environment in sixteen households in LA, California and Paris, France, and offers insights on the relationship between local practices and preferences and children's consumption of fruits and vegetables. Our analysis of video-recorded naturalist data reveals that the consumption of fruits and vegetables is linked to the cultural organization of dinner--what, when and how food is served--and to local beliefs about children's eating practices. We also found that the French model for dinnertime prioritizes the eating of fruits and vegetables more than the American model does. We propose that local eating models should be taken into account in research on childhood obesity and in prevention programs.

Exploring the Sustainability of Home Modifications and Adaptations in Occupational Therapy.

Background. Many occupational therapists make home modification recommendations; however, it is unknown if sustainability considerations (i.e., economic, social, and environmental) are contemplated during this process. Purpose. To understand occupational therapists' perceptions regarding the sustainability of home modifications. Method. This study adopted a qualitative description approach. Researchers utilized semistructured interviews as the primary means of data collection. Findings. The ten female occupational therapists interviewed had three or more years of experience working with home modifications. The analysis identified three themes: It's not easy being green: environmental sustainability, stretching a dollar: financial inequities, and barriers and benefits in the home modification process. Implications. Findings suggest OTs have a varied and a general understanding of how to implement sustainability concepts in their practice. There is also a need to make access to home modifications more equitable. Further research is needed to build a more robust understanding of how OT recommended home modifications can contribute to sustainability.

Complications and Surgeon Health: Resources for individuals and institutions.

The emotional impact of surgical complications on urologists is a significant yet historically under-addressed issue. Traditionally, surgeons have been expected to cope with complications and their psychological effects in silence, perpetuating a culture of perfectionism and 'silent suffering.' This has left many unprepared to handle the emotional toll of adverse events during their training and early careers. Recognizing the gap in structured education on this matter, there is a growing movement to openly address and educate on the emotional consequences of surgical complications. This article underscores the importance of such educational initiatives in the mid-career phase, proposing strategies to promote surgeon health, and psychological safety. It advocates for utilizing Morbidity and Mortality conferences as platforms for peer support, learning from 'near miss' events, and encourages at least annual department-wide discussions to raise awareness and normalize the emotional challenges faced by surgeons. Furthermore, it highlights the role of formal peer support programs, acceptance and commitment therapy, and resilience training as vital tools for promoting surgeon well-being. Resources from various organizations, including the American Urological Association and the American Medical Association, are now available to facilitate these critical conversations. By integrating these resources and encouraging a culture of openness and support, the article suggests that the surgical community can better manage the inevitable emotional ramifications of complications, thereby fostering resilience and reducing burnout among surgeons.

Impact of Dobbs v. Jackson Women's Health Organization on Professional Decision-Making Among Urology Applicants.

MATERIALS AND METHODS: An Institutional Review Board-exempt REDCap survey was distributed through the Society of Academic Urologists to all 508 applicants registered for the 2023 Urology Match following the rank list submission deadline on January 10, 2023. The survey closed on February 1, 2023. Responses were anonymized, aggregated, and characterized using descriptive statistics. Thematic mapping of open text comments was performed by 2 reviewers. RESULTS: The response rate was 42% (215/508). Eighty-eight percent of respondents disapproved of the Dobbs ruling. Twenty percent of respondents (15% male/24% female) eliminated programs in states where abortion is illegal. Fifty-nine percent (51% male/70% female) would be concerned for their or their partner's health if they matched in a state where abortion was illegal, and 66% (55% male/82% female) would want their program to assist them or their partner if they required abortion care during residency. Due to the competitive nature of Urology, 68% of applicants reported feeling at least somewhat obligated to apply in states where abortion legislation conflicts with their beliefs. Of the 65 comments provided by respondents, 4 common themes emerged: (1) avoidance of states with restrictive abortion laws; (2) inability to limit applications because of the competitiveness of urology; (3) impacts on personal health care; and (4) desire for advocacy from professional urology organizations. CONCLUSION: The Dobbs ruling will impact the urology workforce by affecting urology applicants' decision-making regarding residency selection and ranking. Although the competitiveness of the Urology Match pressures applicants to apply broadly, many are taking reproductive health care access into consideration.

Attitudes Among Society of Women in Urology Members Toward Dobbs v. Jackson Women's Health Organization.

OBJECTIVE: To evaluate attitudes of women in urology regarding the Supreme Court ruling Dobbs v. Jackson Women's Health Organization, including impacts on personal/professional decision-making and the urology workforce. METHODS: An IRB-exempt survey including Likert questions on participant views and free text questions was distributed to 1200 members of the Society of Women in Urology on 9/2/2022. Participants were medical students, urology residents, fellows, and practicing/retired urologists over 18. Responses were anonymous and aggregated. Quantitative responses were characterized with descriptive statistics and free-text responses were analyzed using thematic mapping. To complement this analysis, urologist density was mapped by county using 2021 National Provider Identifier data. State abortion laws were categorized based on Guttmacher Institute data on 10/20/2022. Data were analyzed using logistic regression, Poisson regression, and multiple linear regression. RESULTS: 329 respondents completed the survey. 88% disagree/strongly disagree with the Dobbs ruling. 42% of trainees may have changed their rank list if current abortion laws existed during their match. 60% of respondents said Dobbs will impact where they choose their next job. 61.5% of counties had zero urologists in 2021, 76% of which were in states with restrictive abortion laws. Urologist density was inversely associated with abortion law restrictiveness compared with the most protective counties. CONCLUSION: The Dobbs ruling will significantly impact the urology workforce. Trainees may change how they rank programs in states with restrictive abortion laws, and urologists may consider abortion laws when choosing jobs. Restrictive states are at higher risk for worsening access to urologic care.

Primary Ewing Sarcoma of the Testicle in an Adolescent Patient.

Extraosseous Ewing sarcoma with genitourinary tract involvement is rare. We present a case of primary Ewing sarcoma of the testis with review of the literature. While primary Ewing sarcoma of the testis is unusual, it is important to appropriately diagnose. This case emphasizes the benefits of prompt and appropriate evaluation, pathologic work-up, and treatment of testicular tumors.

Self-disgust as a potential mechanism underlying the association between body image disturbance and suicidal thoughts and behaviours.

This study examined whether self-disgust added incremental variance to and mediated the multivariate association between measures of body image disturbance and suicidal thoughts and behaviours. We hypothesized that self-disgust would be associated with suicidal ideation above the effects of body image disturbance, and that self-disgust would mediate the relationship between body image disturbance and suicidal ideation. A total of N=728 participants completed The Body Image Disturbance Questionnaire, The Self-Disgust Scale, and the Suicidal Behaviours Questionnaire-Revised. Suicidality was significantly related to increased levels of self-disgust and body image disturbance, whereas self-disgust was associated with greater body image disturbance. Linear regression analysis showed that self-disgust was associated with suicidal thoughts and behaviours, over and above the effects of body image disturbance. Multiple mediation modelling further showed that self-disgust mediated the relationship between body image disturbance and suicidal thoughts and behaviours. Our findings highlight the role of self-disgust in the context of body image disturbance and support the notion that body image disturbance is associated with aversive self-conscious emotions. Interventions aiming to reduce the risk of suicidality in people with body image disturbance may address self-disgust and negative self-conscious emotions.

Women in Leadership in Urology: The Case for Increasing Diversity and Equity.

There is a persistent male gender predominance in urology, especially with respect to female representation in leadership. We review the current status of women in urology leadership, discuss challenges women face in leadership positions, present the case for adopting inclusive practices that increase diversity and gender equity in urology leadership, and review the potential benefits of such an expansion. We discuss practical strategies to grow the role of women in urologic leadership, including increasing mentorship, modifying academic promotion criteria, and addressing implicit bias, while presenting a roadmap toward achieving equity and diversity at the highest ranks of urologic leadership.

Extrauterine adenomyoma located in the inguinal region: a case report of a 44-year-old woman.

Adenomyomas are benign tumours made of smooth muscle cells, endometrial glands and stroma. An extrauterine location is extremely rare with an unknown pathogenesis. Preoperative diagnosis is challenging and pathologic examination is necessary to confirm the diagnosis. Here we present a case report of a 44-year-old woman with a painful non-reducible mass in the right inguinal region without fever or other alarming symptoms 2 months after a laparoscopic hysterectomy. She was treated with a surgical resection of the mass. Extrauterine adenomyoma is a very uncommon entity. Preoperative workup is challenging, as confirmation of the diagnosis can only be achieved by histopathological analysis following surgical excision.

Two-year Outcome of Quality of Life and Health Status for the Elderly with Chronic Limb-threatening Ischemia.

PURPOSE: In elderly patients with chronic limb-threatening ischemia (CLTI), there is little scientific understanding of the long-term changes of quality of life (QoL) and health status (HS) after treatment. The primary goal of this study was to provide long-term QoL and HS results for elderly CLTI patients after therapy. Treatments consisted of endovascular revascularization, surgical revascularization, or conservative treatment. Furthermore, the aim of this study was to identify the distinctive trajectories of QoL and HS. PATIENTS AND METHODS: CLTI patients aged ≥70 years were included in a prospective observational cohort study with a two-year follow-up. The WHOQOL-BREF was used to asses QoL. The 12-Item Short Form Health Survey was used to measure HS. The QoL and HS scores were compared to the scores in the general elderly Dutch population. Latent class trajectory analysis was used. RESULTS: A total of 195 patients were included in this study. After two years, in all treatment groups patients showed significantly higher physical QoL score compared to baseline and there was no significant difference with the corresponding values in the elderly Dutch population. In the latent class trajectory analysis, there were no overlapping risk factors for poorer QoL or HS. CONCLUSION: This study shows that QoL levels in surviving elderly CLTI patients in the long-term do not differ from the corresponding values for elderly in the general population. There were no disparities in sociodemographic, clinical and treatment characteristics associated with poorer QoL and HS. This study was carried out to encourage further analysis of the influence of biopsychosocial characteristics on QoL and HS in elderly CLTI patients.

Stent graft treatment as a bridge to surgery for a secondary aortoduodenal fistula.

A secondary aortoduodenal fistula is a rare but a severe late complication after prosthetic abdominal aortic surgery. Currently, there is little consensus regarding the right treatment due to high mortality and morbidity rates. We report the case of a haemodynamically unstable patient with haematemesis on the basis of a secondary aortoduodenal fistula. He was successfully treated by staged stent graft placement followed by surgical graft excision and autogenous deep vein reconstruction. In haemodynamically unstable patients or in patients where open repair is not feasible in the acute setting of secondary aortoduodenal fistula, we advocate the use of a 2-staged endovascular and surgical approach to improve short- and long-term outcomes.

Holmium:Yttrium-Aluminum-Garnet Laser Pulse Type Affects Irrigation Temperatures in a Benchtop Ureteral Model.

Introduction: MOSES™ technology is a holmium:yttrium-aluminum-garnet laser pulse mode shown to minimize stone retropulsion. This may facilitate lithotripsy at higher power settings. However, power and heat production are proportional, and temperatures capable of tissue injury may occur during ureteroscopic lithotripsy. Although previous in vitro studies demonstrate the importance of irrigation and activation time on heat production, the impact of pulse type has not been evaluated. Methods: A flexible ureteroscope with a 365 µm laser fiber was placed in an 11/13 F access sheath inserted into a 50 mL saline bag to simulate a ureter, renal pelvis, and antegrade irrigant flow. A thermocouple was placed adjacent to the laser tip, and the laser fired for 30 seconds at 0.6 J/6 Hz, 0.8 J/8 Hz, 1 J/10 Hz, 1 J/20 Hz, and 0.2 J/70 Hz at irrigation pressure of 100 mmHg. Four runs were tested per setting using short pulse, long pulse (LP), MOSES-contact (MC), and MOSES-distance (MD) modes. The mean temperature changes (dT) were compared and thermal dose was calculated in cumulative equivalent minutes at 43°C (CEM43) using an adjusted baseline of 37°C. CEM43 ≥ 120 minutes was considered the tissue injury threshold. Results: At 0.8 J/8 Hz, LP produced the greatest dT, significantly higher than MC (p = 0.041). CEM43 did not exceed the injury threshold. At 1 J/10 Hz, dT was significantly higher for LP versus MC and MD (p = 0.024 and 0.045, respectively). Thermal dose remained below the injury threshold. No differences in dT were seen between pulse types at 0.6 J/6 Hz, 0.2 J/70 Hz, or 1 J/20 Hz. At 1 J/20 Hz, thermal dose exceeded the injury threshold for all pulse types within 3 seconds. Conclusions: Laser pulse type and length seemed to impact heat production in our ureteral model. LP produced significantly greater temperatures at 0.8 J/8 Hz and 1 J/10 Hz relative to MOSES settings. Fortunately, thermal dose remained safe at these settings. Both LP and MOSES technology have been shown to reduce stone retropulsion. At power ≤10 W, the latter may confer this advantage with decreased heat production.
