RESUMEN
PURPOSE: To present the initial prospective clinical assessment of the ILY® robotic ureteroscopy manipulator platform, focusing on its safety and effectiveness. METHODS AND MATERIALS: Data gathered from 31 kidney units which underwent elective robotic flexible ureteroscopy (FURS) for renal stone management utilizing the ILY® robotic system. Patient demographics, stone characteristics, surgical durations, perioperative and post-operative complications, and follow-up parameters were collected. Our primary outcome was evaluating the efficacy and safety of the ILY® robotic ureteroscopy for treating kidney stones. Therefore, we analyzed complication rates, surgical durations, and the stone-free rate during follow-up. RESULTS: Our cohort consisted of 29 patients, presenting with 45 stones with a median volume of 736.22 mm3. The median operation time was 85 min, accompanied by 3 min for robot draping, 3.5 min for robot docking, 48 min of console operation, and lasing time of 36.75 min. Post operative stay for all patients was 1 day, while complications were observed in 9.68% of cases. Notably, all complications were classified as CVD (Clavien-Dindo) class 1 due to pain requiring emergency department visit. The stone-free rate achieved was 93.55%, and none of the patient required reoperation for the treated stone. CONCLUSION: In the first prospective clinical experience of the ILY® robotic FURS, we demonstrated its efficacy and safety. To further investigate its clinical practical value, additional investigations are warranted, including direct comparative analyses with manual flexible ureteroscopy techniques.

BACKGROUND: Although prostate cancer is a prevalent malignancy worldwide, its clinical presentation and management in the Middle East are not well-documented. This study aims to provide insights into the initial clinical presentation and management of prostate cancer in this region. METHODS: A retrospective review was conducted on seven institutional databases from six Middle Eastern countries, including Türkiye, Lebanon, Iraq, Syria, Bahrain, and Jordan, to identify patients diagnosed with prostate cancer in 2021. Descriptive analysis was performed on the collected data to provide an overview of the demographic, clinical, and treatment variables. RESULTS: A total of 1,136 patients were identified with a median age of 70 (range, 50-84). Most patients (78%) received their prostate cancer diagnosis after presenting with symptoms, as opposed to routine PSA screening. At the time of diagnosis, 35% of men had clinical T3 or T4 disease, 54% with Stage IV disease and 50% with Gleason score ≥ 8. Regarding treatment, 20% of non-metastatic and 22% of metastatic patients received no treatment. CONCLUSION: Most men in this study sought prostate cancer evaluation due to symptoms and were subsequently diagnosed with advanced-stage disease, providing a foundation for future research aimed at understanding the underlying factors behind the observed trends and enabling informed interventions.

PURPOSE: We aimed to compare perioperative outcomes, post-operative complications, and opioid use between AirSeal® and non-AirSeal® robotic-assisted radical prostatectomy (RARP). METHODS: We retrospectively collected data on 326 patients who underwent elective RARP at our institution either with or without AirSeal®. The first 60 cases were excluded accounting for the institutions' learning curve of RARP. Patient demographics, oncologic, pathologic, and surgical characteristics between AirSeal® and non-AirSeal® cases were compared. Furthermore, outcomes of interest including operative time, length of stay, morbidity, and opioid use for pain management were compared between the two groups. Univariate linear and logistic regression models were developed. RESULTS: The AirSeal® group consisted of 125 (38.3%) patients while the non-AirSeal® group consisted of 201 (61.7%) patients. No statistically significant difference was seen in terms of patient demographics, oncologic characteristics, surgical characteristics, and pathologic characteristics between the two groups. In addition, univariate linear regression showed that RARP with AirSeal® displayed shorter operative times by 12.3 min and a shorter length of hospital stay by 0.5 days compared to the non-AirSeal® group (p < 0.001). Furthermore, the AirSeal® group witnessed lower odds of Clavien-Dindo (CVD) Class > 2 complications (OR = 0.102) and a lower need for opioid use (OR = 0.49) compared to the non-AirSeal® group (p < 0.022). CONCLUSION: RARP using AirSeal® is associated with shorter operative times, shorter length of hospital stays, lower odds of CVD > 2 complications, and lower odds of opioid use with respect to non-AirSeal® RARP. The efficacy and cost effectiveness of using the AirSeal® system during RARP should be further studied and evaluated by clinical trials.

BACKGROUND: To explore reoperation rates for different radical nephrectomy (RN) approaches that are experiencing a shift from open radical nephrectomy (ORN) toward minimally invasive surgery (MIS), we aimed to compare reoperation rates along with their culprit etiologies between the different types of surgical approaches for RN. METHODS: The national surgical quality improvement program dataset was used to select patients who underwent RN between the years 2012-2019. A 1:1 propensity score matched analysis was used. Reoperation rates and causes were then compared between open and MIS approach. RESULTS: The propensity matched cohort included 15,294 patients. Reoperation rates due to large bowel injury (0.01 vs. 0.14%), vascular injury (0.07 vs. 0.22%), and other abdominal (0.5 vs. 0.77%) were more common in ORN as compared to MIS (MIS vs. ORN, respectively, p < 0.034). Reoperation due to hernia (0.14 vs. 0.03%) was more common in MIS as compared to ORN (p = 0.027). No difference was seen for small bowel injury and incision/wound debridement. General reoperation (1.61 vs. 2.22%) and mortality (0.57 vs. 1.47%) were also more common in ORN as compared to MIS (p < 0.008). CONCLUSION: Reoperation due to large bowel injury, vascular injury, and other abdominal was more likely to occur in ORN. Whereas reoperation due to hernia was more likely to occur in MIS. Surgical approach was an independent risk factor for immediate and early reoperation rates in RN patients. These results could be used to counsel patients pre-operatively on possible surgical approaches and complications.

OBJECTIVES: To describe and analyze the learning curve (LC) of aquablation for the treatment of benign prostatic obstruction and determine the number of cases needed to achieve acceptable surgical safety, efficiency, and efficacy. METHODS: A retrospective analysis of prospectively maintained aquablation databases from France, Lebanon, and Spain was conducted. The combined LC of three surgeons was defined by trifecta and pentafecta outcomes. Trifecta reflected efficiency and safety: operative time < 60 min, hemoglobin reduction ≤ 2 mg/dL, and no 90 day Clavien-Dindo grade ≥ 2 complications. Pentafecta reflected effectiveness: percent reduction in International Prostate Symptom Score (IPSS) and ejaculation preservation. The combined LC was plotted using a moving average with polynomial fitting. RESULTS: The cohort included 175 consecutive patients. Median (IQR) prostate volume was 70 (50-91) cc, and baseline IPSS was 23 (18-27). The achievement of trifecta exceeded 50% after 4 cases, and 70% after 50 cases. Pentafecta achievement exceeded 50% after 38 cases. Logistic regression showed significant improvement in hemoglobin reduction and ejaculation preservation. Grade ≥ 2 complication was not affected by experience, and neither was 3 month %IPSS reduction as 94% of patients showed ≥ 50% symptoms' improvement. CONCLUSION: Aquablation is associated with a quick learning curve for the defined trifecta and pentafecta outcomes. It provided effective LUTS relief and low complication rates independent of surgeon experience. Hemoglobin drop and ejaculatory function preservation were the two factors influenced by the surgeons' LC. Training to reduce operative time, standardization of hemostasis techniques, and early assistance to improve veru-protection zone planning are keys to quicker learning.

INTRODUCTION: The study aimed to construct and validate a risk prediction model for incidence of postoperative renal failure (PORF) following radical nephrectomy and nephroureterectomy. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database years 2005-2014 were used for the derivation cohort. A stepwise multivariate logistic regression analysis was conducted, and the final model was validated with an independent cohort from the ACS-NSQIP database years 2015-2017. RESULTS: In cohort of 14,519 patients, 296 (2.0%) developed PORF. The final 9-factor model included age, gender, diabetes, hypertension, BMI, preoperative creatinine, hematocrit, platelet count, and surgical approach. Model receiver-operator curve analysis provided a C-statistic of 0.79 (0.77, 0.82; p < 0.001), and overall calibration testing R2 was 0.99. Model performance in the validation cohort provided a C-statistic of 0.79 (0.76, 0.81; p < 0.001). CONCLUSION: PORF is a known risk factor for chronic kidney disease and cardiovascular morbidity, and is a common occurrence after unilateral kidney removal. The authors propose a robust and validated risk prediction model to aid in identification of high-risk patients and optimization of perioperative care.

PURPOSE: To evaluate the feasibility of telementoring for aquablation by comparing the outcomes of onsite versus telemetry proctoring. METHODS: The telemetry device of choice was Proximie, an innovative digital platform that uses live video stream with an augmented reality technology. Our study retrospectively reviewed outcomes from our IRB approved prospective Aquablation database from March 2018 till October 2019. Procedures were guided by a proctor either onsite or remotely through telemetry. One-way ANOVA or Chi-square was used to compare perioperative parameters and mixed model ANOVA was used to compare functional outcomes. RESULTS: Our data included 59 patients who underwent a proctored-based Aquablation of which 21 were telementor guided and 38 were onsite guided. The initial ten procedures were done with the latter approach. There was no statistical difference in age, comorbidities, prostate size, and baseline serum markers amongst the two groups. In contrast, telementor guidance was associated with increased general anaesthesia use (76.2% vs. 21.1%) and haemostatic cauterization (81.0% versus 47.4%) with a p value < 0.00001 and 0.004 respectively. However, the main procedure outcomes: operative time, time to Foley catheter removal, haemoglobin drop, urinary retention, and adverse events were statistically insignificant (p value > 0.05). CONCLUSION: Following an initial phase of onsite proctoring, telementoring can be safely used in the adoption phase of a new robotic technology. This approach allowed more flexibility in patient scheduling and reduced travel costs with similar surgical outcomes.

OBJECTIVE: To determine if athermal methods are as effective in preventing blood transfusions as the use of cautery across various prostate volumes following prostate tissue resection for benign prostatic hyperplasia using Aquablation. PATIENTS AND METHODS: The current commercial AQUABEAM robot that performs Aquablation therapy was first used in 2014. Since then numerous clinical studies have been conducted in various countries; Australia, Canada, Germany, India, Lebanon, Spain, New Zealand, United Kingdom, and the United States. All of the clinical trial data since 2014 were pooled with the early commercial procedures from France, Germany, and Spain to determine the effectiveness of haemostatic techniques in reducing the transfusion rate in patients after Aquablation. RESULTS: In all, 801 patients were treated with Aquablation therapy from 2014 to early 2019. The mean (SD, range) prostate volume was 67 (33, 20-280) mL and 31 (3.9%) transfusions were reported. The largest contributing factor to transfusion risk was prostate size and method of traction. There was an increasing risk of transfusions in larger prostates when robust traction using a catheter-tensioning device (CTD) without cautery was used, ranging from 0.8% to 7.8% in prostates ranging from 20 to 280 mL. However, when standard traction (taping the catheter to the leg, gauze knot synched up to the meatus, or no traction at all) was used and where the surgeon performed bladder neck cautery only when necessary, the risk of transfusion was 1.4-2.5% in prostates ranging from 20 to 280 mL. CONCLUSIONS: While the athermal subgroup with robust traction with a CTD had comparable transfusion rates for smaller prostates, the risk increased significantly as prostate volume increased. With standard traction methods and selective bladder neck cautery, the risk of transfusion was reduced to 1.9% across all prostate sizes.

PURPOSE: To compare the perioperative outcomes associated with laser enucleation of the prostate (LEP) and transurethral resection of the prostate (TURP) using a national database. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was reviewed for patients who underwent TURP or LEP from 2008 to 2016. Baseline demographics, comorbidities, and predisposition to bleeding were compared between TURP and LEP. The 30-day perioperative outcomes including operative time, length of hospital stay (LOS), return to the operating room (OR), bleeding requiring transfusion, and organ system-specific complications were compared between the procedures. A multivariate logistic regression analysis was performed, adjusting for the type of surgery and other covariates. RESULTS: The series included 37,577 TURP and 2869 LEP procedures. While TURP was associated with a shorter operative time (55.20 ± 37.80 min) than LEP (102.80 ± 62.30 min), the latter was associated with a shorter hospital stay (1.29 ± 2.73 days) than TURP (2.05 ± 5.20 days). Compared to TURP, LEP had 0.52 (0.47-0.58) times the odds of a LOS > 1 day and 0.67 (0.54-0.83) times the odds of developing urinary tract infections. Nevertheless, no difference was found for other postoperative complications, need for transfusion, and return to OR. CONCLUSION: Real-life data from a large national database confirmed that LEP is a safe and reproducible procedure to treat benign prostatic obstruction. Compared to TURP, LEP was associated with a lower rate of infectious complications and a shorter LOS at the expense of an increased operative time.

PURPOSE: Prostate cancer care in the Middle East is highly variable and access to specialist multidisciplinary management is limited. Academic tertiary referral centers offer cutting-edge diagnosis and treatment; however, in many parts of the region, patients are managed by non-specialists with limited resources. Due to many factors including lack of awareness and lack of prostate-specific antigen (PSA) screening, a high percentage of men present with locally advanced and metastatic prostate cancer at diagnosis. The aim of these recommendations is to assist clinicians in managing patients with different levels of access to diagnostic and treatment modalities. METHODS: The first Advanced Prostate Cancer Consensus Conference (APCCC) satellite meeting for the Middle East was held in Beirut, Lebanon, November 2017. During this meeting a consortium of urologists, medical oncologists, radiation oncologist and imaging specialists practicing in Lebanon, Syria, Iraq, Kuwait and Saudi Arabia voted on a selection of consensus questions. An additional workshop to formulate resource-stratified consensus recommendations was held in March 2019. RESULTS: Variations in practice based on available resources have been proposed to form resource-stratified recommendations for imaging at diagnosis, initial management of localized prostate cancer requiring therapy, treatment of castration-sensitive/naïve advanced prostate cancer and treatment of castration-resistant prostate cancer. CONCLUSION: This is the first regional consensus on prostate cancer management from the Middle East. The following recommendations will be useful to urologists and oncologists practicing in all areas with limited access to specialist multi-disciplinary teams, diagnostic modalities and treatment resources.

BACKGROUND: Positive surgical margin (PSM) is a predictor of biochemical recurrence (BCR) following radical prostatectomy (RP). Attempts to stratify PSM based on linear length, Gleason score, location and number have failed to add to predictive models using margin status alone. We evaluated the prognostic significance of Ki-67 expression in this setting. METHODS: Immunohistochemical staining for Ki-67 was done on prostatectomy specimens from 117 patients who had a PSM. Ki67 expression was measured at the margin and in the index lesion. Patients were dichotomized based on Ki-67 expression into three groups. Group 1 with no Ki-67 expression, Group 2 with Ki-67 ≤ 2%, and Group 3 with Ki-67 ≥ 3%. To eliminate the impact of the adjuvant treatment (AT) on the outcome, data were analyzed by the Cox proportional hazards in which AT was Considered as a time-dependent covariate. RESULTS: The discordance rate of Ki-67 expression between matched index lesion and margin specimens was 44/117 (37.6%). There was a trend for higher risk of BCR (HR:2.06, (0.97-4.43), P = 0.06) in patients expressing high Ki67 at the surgical margin although this was not statistically significant. However High Ki-67 expression in the index lesion was an independent predictive factor for BCR in this subset of patients. (HR:4, (1.64-9.80), P = 0.002). CONCLUSION: High Ki67 expression in the index prostate cancer lesion is an independent predictor of BCR in patients with positive surgical margin following radical prostatectomy. Our findings need to be validated in a larger cohort.

BACKGROUND AND OBJECTIVE: The aim of this study was to evaluate the stone-free status (SFS) rate and complications after flexible ureteroscopy (fURS) for treatment of renal stones using a flexible and navigable suction (FANS) ureteral access sheath. METHODS: Data for adults undergoing fURS in 25 centers worldwide were prospectively collected (August 2023 to January 2024). Exclusion criteria were abnormal renal anatomy and ureteral stones. All patients had computed tomography scans before and within 30 d after fURS with a FANS ureteral access sheath. SFS was defined as follows: grade A, zero fragments; grade B, a single fragment ≤2 mm; grade C, a single fragment 2.1-4 mm; and grade D, single/multiple fragments >4 mm. Data for continuous variables are presented as the median and interquartile range (IQR). Multivariable logistic regression was performed to evaluate predictors of grade A SFS. KEY FINDINGS AND LIMITATIONS: The study enrolled 394 patients (59.1% male) with a median age of 49 yr (IQR 36-61). The median stone volume was 1260 mm3 (IQR 706-1800). Thulium fiber laser (TFL) was used in 45.9% of cases and holmium laser in the rest. The median lasing time was 18 min (IQR 11-28) and the median operative time was 49 min (IQR 37-70). One patient required a blood transfusion and 3.3% of patients had low-grade fever. No patient developed sepsis. Low-grade ureteral injury occurred in eight patients (2%). The grade A SFS rate was 57.4% and the grade A + B SFS rate was 97.2%, while 2.8% of patients had grade C or D SFS. Eleven patients underwent repeat fURS. Multivariable analysis revealed that a stone volume of 1501-3000 mm3 (odds ratio 0.50) and of >3000 mm3 (odds ratio 0.29) were significantly associated with lower probability of grade A SFS, while TFL use was associated with higher SFS probability (odds ratio 1.83). Limitations include the lack of a comparative group. CONCLUSIONS AND CLINICAL IMPLICATIONS: fURS using a FANS ureteral access sheath resulted in a high SFS rate with negligible serious adverse event and reintervention rates. PATIENT SUMMARY: We looked at 30-day results for patients undergoing telescopic laser treatment for kidney stones using a special type of vacuum-assisted sheath to remove stone fragments. We found a high stone-free rate with minimal complications.
RESUMEN
OBJECTIVE: To identify the risk of failure of active surveillance (AS) in men who had the Prostate Cancer Research International: Active Surveillance (PRIAS) criteria and had undergone radical prostatectomy (RP), by studying as primary endpoints the risk of unfavourable disease in RP specimens (stage >T2 and/or Gleason score >6) and of biochemical progression after RP. PATIENTS AND METHODS: We assessed 626 patients who had the PRIAS criteria for AS defined as T1c/T2, PSA level of ≤10 ng/mL, PSA density (PSAD) of <0.2 ng/mL per mL, Gleason score of <7, and one or two positive biopsies. All patients underwent immediate RP at our department between January 1991 and December 2010. Multivariate logistic regression was used to test factors correlated with the risk of unfavourable prostate cancer. The risk of progression was tested using multivariate Cox regression models. Biochemical recurrence-free survival (BFS) was established using the Kaplan-Meier method. RESULTS: Pathological study of RP specimens showed upstaging (>T2) in 129 patients (20.6%), upgrading (Gleason score >6) in 281 (44.9%) and unfavourable disease in 312 patients (50%). There was a statistically non-significant trend for BFS at P = 0.06. Predictors of favourable tumours were age <65 years (P = 0.005), one vs two positive biopsies (P = 0.01) and a biopsy core number >12 (P = 0.005). Preoperative factors predicting disease progression were a PSAD of >0.15 ng/mL(2) (P = 0.008) and biopsy core number of ≤12 (P = 0.017). CONCLUSIONS: Even with stringent AS criteria, the rate of unfavourable disease remains high. Predictive factors of unfavourable disease and biochemical progression should be considered when including patients in AS protocols.

UNLABELLED: What's known on the subject? and what does the study add?: Local relapse of renal cell carcinoma following radical nephrectomy is rare, and surgical removal provides the only opportunity for cure. Open surgery has been established as the usual approach for these tumours. It is, however, associated with significant morbidity. Our study describes the largest series of laparoscopic treatment of local relapse of renal cell carcinoma with the longest follow-up. We show that the laparoscopic approach is feasible in expert centres. It provides faster recovery and fewer complications with satisfactory oncological outcomes in selected patients. OBJECTIVE: To assess the feasibility and oncological outcomes of laparoscopic treatment for local relapse of renal cell carcinoma. PATIENTS AND METHODS: Nine patients were treated by a pure laparoscopic approach for local recurrence of a renal tumour between 2005 and 2011 by a single surgeon (HB), following an initial open radical nephrectomy for the primary tumour. Clinical and histopathological data were collected prospectively and analysed retrospectively. Seven patients were treated by a transperitoneal approach and two patients had a retroperitoneal approach. RESULTS: Relapse occurred within a mean time of 83 months (7-168) following nephrectomy. Recurrent tumour size varied from 2.5 to 4.5 cm. All surgeries were performed laparoscopically without need for conversion. Mean operative duration was 144 min (40-240), mean estimated blood loss was 430 mL (50-1300) and mean hospital stay was 4.5 days (3-6). Three patients had Clavien grade I intraoperative complications. Late complications were noted in two patients (Clavien I and IIIb). Pathology confirmed clear cell carcinoma in all patients with an absence of sarcomatoid features and negative surgical margins. Three patients had neoadjuvant treatment and two patients had adjuvant treatment. In all, 67% of patients were disease free with a mean follow-up period of 3 years. CONCLUSIONS: Surgical removal of isolated local recurrence remains the only possibility of cure in patients with renal cell carcinoma. We demonstrated that the laparoscopic approach is a safe and feasible alternative treatment option for selected cases with low morbidity and satisfactory oncological outcomes.

OBJECTIVES: To establish the rate of higher risk criteria in various definitions of an active surveillance population. PATIENTS AND METHODS: Over a period of 10 years, 1161 patients were diagnosed with prostate cancer and underwent radical prostatectomy at our institution. Statistical analysis was performed comparing the rates of upgrading, extracapsular extension, seminal vesical involvment and unfavourable disease (Gleason score upgrading >6 and/or T3 disease) for six groups of patients eligible for the University of Toronto, Royal Marsden, John Hopkins, University of California San Francisco, Memorial Sloan Kettering Cancer Center and Prospective Randomized International Active Surveillance. RESULTS: Active surveillance protocols including patients with biopsy Gleason score 3+4 (Royal Marsden) had significantly higher rates of extracapsular extension (P = 0.009), upgrading to pathological Gleason >3+4 (P = 0.004) and unfavourable disease (P = 0.001) compared to the most stringent John Hopkins criteria. Unfavourable disease was found in more than 40% of patients in all series with no significant difference between the Gleason 6 protocols. Biochemical recurrence-free survival at 5 and 10 years was 76.7% and 63.3% for the entire cohort. Positive margins (P < 0.001), pT3 tumours (P = 0.006) and unfavourable disease (P < 0.001) were significant predictors of biochemical recurrence. CONCLUSIONS: Active surveillance in patients with Gleason 3+4 presents a risk of missing unfavourable disease and should be limited to older patients with comorbidities. The differences in inclusion criteria between Gleason 6 protocols did not have a significant impact on the pathological results.

Background: Radical cystectomy (RC) is considered a complex procedure that entails significant morbidity and mortality. Objectives: We aimed to determine pre-operative patient characteristics that help predict a prolonged length of hospital stay (PLOS) following RC. Design and Methods: The American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database was used to select patients who underwent RC between the years 2011 and 2020. Prolonged length of stay was defined as a hospital stay ⩾9 days. We compared patient demographics, pre-operative labs, surgical characteristics, and medical history between patients with or without PLOS. Multivariable logistic regression models controlling for pre-operative characteristics and propensity score matching for post-operative complications were conducted to control for possible confounders. Results: The analysis yielded details of 19,158 RC patients of which 6007 (31%) patients had a PLOS. Patients with PLOS were more likely to have post-operative complications that could serve as predictors for the PLOS rather than their pre-operative characteristics. Hence, we matched our cohort for these complications. After matching, patient pre-operative characteristics that predict PLOS included female gender (Odds Ratio (OR) = 5.91), 10-year increase in age (OR = 1.15), non-White race (OR = 1.98), partially or totally dependent functional health status (OR = 2.86), bleeding disorders (OR = 4.67), congestive heart failure (OR = 1.59), pre-operative transfusion (OR = 3.03), and a 20-min increase in operative time (OR = 1.01) (p < 0.046). Conclusion: Patient demographics and pre-operative factors can help predict PLOS in RC patients. These predictors could serve as tools for patient counseling and risk stratification.
RESUMEN
INTRODUCTION: To assess the modified Global Leadership Initiative on Malnutrition (mGLIM) status as a predictor of postoperative mortality and morbidity in patients undergoing Radical Cystectomy (RC). METHODS AND MATERIALS: The American College of Surgeons - National Surgical Quality Improvement Program (ACS-NSQIP) dataset was used to select patients who underwent RC between the years 2011 to 2020. A positive mGLIM status includes patients with preoperative albumin levels < 3.5 g/L or patients with ≥ 10% weight loss over 6 months or BMI ≤ 21 kg/m2. We compared prolonged length of stay, mortality, major morbidity and Clavien-Dindo complications between mGLIM positive and negative patients. A multivariable logistic regression model was also performed to control for possible confounders. Furthermore, a sensitivity analysis was performed by propensity score matching. RESULTS: Our cohort consisted of 12,760 patients who underwent RC. The matched cohort yielded 4864 matched patients. After propensity score matching, patients with a positive mGLIM status had higher odds of prolonged length of stay (OR = 1.99, 95%CI [1.75, 2.27]), mortality (OR 1.56, 95%CI [1.08, 2.26]), major morbidity (OR = 1.69, 95%CI [1.51, 1.90]), Clavien-Dindo class I and II (OR = 1.77, 95%CI [1.58, 1.99]), and lower odds of Clavien-Dindo class III (OR = 0.72, 95%CI [0.57, 0.92]) as compared to those with a negative mGLIM status (P < .018). CONCLUSION: A positive mGLIM status is associated with prolonged hospital stay, morbidity, and mortality following RC. This indicates that the mGLIM criteria could serve as an independent predictor of morbidity and mortality in an attempt to optimize patient counseling and preoperative care.

Background: Robotic-assisted radical prostatectomy (RARP) has been found to be comparable and, in some cases, favorable to open surgical approaches, while being used in a frailer population. Objectives: We aimed to illustrate the trend in population frailty and compare morbidity and mortality postoperatively in patients who underwent RARP. Design and Methods: The National Surgical Quality Improvement Program data set was used to select patients who underwent RARP between the years 2011-2019. Age, frailty indicators, surgical characteristics, and perioperative morbidity and mortality were compared between the years 2011-2019 using the chi-square test (χ2) for categorical variables and the one-way analysis of variance (ANOVA) for continuous variables. Results: Our patient population consisted of 66,683 patients who underwent RARP. There was an increase in mean age and frailty indicated by an increase in 5-item frailty score ⩾2, metabolic syndrome index = 3, and American Society of Anesthesiologists' (ASA) class ⩾3 between the years 2011-2019 (p < 0.001). Whereas the rate of mortality and morbidity, indicated by postoperative Clavien-Dindo grade ⩾4 and major morbidity, remained the same over the same period (p > 0.264). Furthermore, operative time and length of stay decreased over the same period (p < 0.001). Conclusion: RARP is being performed on more frail patients, with no added morbidity or mortality.
RESUMEN
Introduction: The goal of the study is to assess burnout among postgraduate medical trainees, evaluate the association with sociodemographic features and offer potential wellness strategies for leaders responsible for their education, training, management, and wellbeing. Methods: The Oldenburg Burnout Inventory was used. The web-based, voluntary, and anonymous survey was sent to postgraduate medical trainees from various specialties and all years of training in a tertiary medical center in Beirut, Lebanon. Additional questions were added after the survey regarding reporting channels for burnout and possible interventions for wellbeing. Results: The total number of valid responses are 188. The prevalence rates of high burnout are 37.2% for disengagement and 51.1% for exhaustion. There is a significant difference between the mean of exhaustion and gender (p = 0.003). There is a significant difference between the mean of disengagement and year of training (p = 0.017). There is a significant difference between the mean of exhaustion and year of training (p = 0.029). There is a significant difference between the frequency of disengagement and year of training (p = 0.027). Conclusion: The study reveals how postgraduate medical training program is impacted by the existing challenges from social, health, and financial standpoint, along with the instabilities encountered such as multiple wars and port blast in 2020 and how these variables aggravate burnout. Burnout severely impacts the education and training of PGMT and promoting wellbeing can help reverse the process. Findings contribute to establishing effective strategic interventions for leaders in healthcare management to adopt.

Objectives: Over the past 20 years, the utility of partial nephrectomy (PN), compared to radical nephrectomy (RN), for the management of localized renal cell carcinoma (RCC) has progressively increased, particularly for larger and more complex masses. We sought to compare the recurrence-free survival (RFS) outcomes of PN versus RN in a single-institution cohort. Methods: Between 2002 and 2017, 228 patients underwent RN or PN for lcT1a-T2b, N0M0 RCC at a single tertiary referral center, performed by five surgeons. The clinical end point result was (local or distant) RFS. Univariate and multivariate (cox regression) models were used to evaluate the association between type of surgery (PN vs. RN) and RFS, in the overall cohort and in a subgroup of patients with cT1b. Results: The median age was 59 (interquartile range [IQR] 48-66), and the median tumor size was 4.5 cm (IQR 3-7). There were 128 PN and 100 RN. Over a median follow-up of 4.2 years (IQR 2.2-6.9), the Kaplan-Meier analysis showed no significant RFS difference between PN and RN (logrank P = 0.53). On multivariate analysis, pathologic stage ≥T2a, Fuhrman Grade ≥3, and chromophobe histology were associated with a worse RFS. PN was not significantly associated with diminished RFS (Hazard ratio [HR] 1.78, 95% confidence interval [CI] 0.74-4.3, P = 0.199) in the overall cohort compared to RN. However, in the cT1b subgroup, PN was associated with a significant increase in recurrence compared to RN (HR = 12.4, 95% CI 1.45-133.4, P = 0.038). Conclusions: Our institutional data highlight the possibility of compromise in RFS for clinically localized RCC treated with PN compared to RN, particularly for larger and more complex masses. These data raise concern, especially in light of the nonproven association of survival benefit of PN over RN, warranting future randomized prospective studies for further evaluation.
