RESUMEN

BACKGROUND: Inguinal lymph node dissection plays an important role in the management of melanoma, penile and vulval cancer. Inguinal lymph node dissection is associated with various intraoperative and postoperative complications with significant heterogeneity in classification and reporting. This lack of standardization challenges efforts to study and report inguinal lymph node dissection outcomes. The aim of this study was to devise a system to standardize the classification and reporting of inguinal lymph node dissection perioperative complications by creating a worldwide collaborative, the complications and adverse events in lymphadenectomy of the inguinal area (CALI) group. METHODS: A modified 3-round Delphi consensus approach surveyed a worldwide group of experts in inguinal lymph node dissection for melanoma, penile and vulval cancer. The group of experts included general surgeons, urologists and oncologists (gynaecological and surgical). The survey assessed expert agreement on inguinal lymph node dissection perioperative complications. Panel interrater agreement and consistency were assessed as the overall percentage agreement and Cronbach's α. RESULTS: Forty-seven experienced consultants were enrolled: 26 (55.3%) urologists, 11 (23.4%) surgical oncologists, 6 (12.8%) general surgeons and 4 (8.5%) gynaecology oncologists. Based on their expertise, 31 (66%), 10 (21.3%) and 22 (46.8%) of the participants treat penile cancer, vulval cancer and melanoma using inguinal lymph node dissection respectively; 89.4% (42 of 47) agreed with the definitions and inclusion as part of the inguinal lymph node dissection intraoperative complication group, while 93.6% (44 of 47) agreed that postoperative complications should be subclassified into five macrocategories. Unanimous agreement (100%, 37 of 37) was achieved with the final standardized classification system for reporting inguinal lymph node dissection complications in melanoma, vulval cancer and penile cancer. CONCLUSION: The complications and adverse events in lymphadenectomy of the inguinal area classification system has been developed as a tool to standardize the assessment and reporting of complications during inguinal lymph node dissection for the treatment of melanoma, vulval and penile cancer.

RESUMEN

BACKGROUND: Many adrenal tumors are deemed radiologically indeterminate and surgically removed. Adrenal tissue, like parathyroid glands, exhibits near-infrared autofluorescence (NIRAF) properties. This study was designed to investigate the potential of NIRAF to differentiate benign versus malignant adrenal tumors. METHODS: Patients undergoing adrenalectomy between October 2021 and May 2023 were prospectively studied. Adrenalectomy specimens were inspected with NIRAF imaging. Specimen autofluorescence (AF) characteristics were recorded. Comparisons were made between different tumor types and a logistic regression model was constructed to differentiate benign versus malignant tumors. A receiver operating characteristic curve was used to identify an optimal AF threshold differentiating benign versus malignant tumors. RESULTS: A total of 108 adrenal specimens were examined: adrenocortical adenomas/other benign lesions (n = 72), pheochromocytomas (n = 18), adrenocortical neoplasms of uncertain behavior (n = 4), and malignant tumors (n = 14). A significant difference in normalized AF intensity was identified when comparing adrenocortical adenomas (3.08 times background) with pheochromocytomas (1.95, p = 0.001) and malignant tumors (1.11, p < 0.0001). The Area Under the Curve differentiating benign vs malignant tumors was 0.87, with an optimal normalized AF threshold at 1.93. CONCLUSIONS: Different adrenal pathologies exhibit diverse AF properties. These findings suggest a potential intraoperative utility of NIRAF in predicting benign versus malignant nature for radiologically indeterminate adrenal tumors.

RESUMEN

OBJECTIVES: Prior studies have found lower arteriovenous fistula (AVF) creation rates in Black and Hispanic patients. Whether this is due to health care disparities or other differences is unclear. Our objective was to evaluate the racial/ethnic differences in initial surgical access type within a high-volume, safety net system with predominantly Black and Hispanic populations. METHODS: A retrospective review of initial hemodialysis (HD) access in consecutive cases between 2014 and 2019 was conducted from all five safety net hospitals in a health care system that primarily treats underserved patients. Patient data collected included race, ethnicity, sex, comorbidities, and initial arteriovenous (AV) access type (AV fistula [AVF] vs AV graft [AVG]). The rates of cephalic vein-based AVF (CAVF; radiocephalic, brachiocephalic) were compared with basilic and brachial vein AVF (BAVF), because the latter are performed as two stages. Bivariate and multivariate logistic regression models were adjusted for demographic and clinical variables to evaluate the relationship between race/ethnicity, surgical access type, and comorbid conditions. RESULTS: We included 1334 patients (74% Hispanic, 9% Black, 7% Asian, 2% White, 8% other) who underwent first-time surgical HD access creation. The majority were male (818 [63%]). Medical comorbidities were equal among groups, except for chronic obstructive pulmonary disease and stroke, which were higher in Black patients (P < .005 and P = .005, respectively). Overall, 1303 patients (98%) underwent AVF creation and 31 AVG creation (2%), with no difference between race/ethnicity in AVF vs AVG creation. Of the AVF cohort, 991 (76%) had a CAVF and 312 (24%) had a BAVF. Males were more likely than females to get a CAVF (65% vs 35%; P = .002). CONCLUSIONS: Within our safety net health system, where most patients are under-represented minorities, nearly all patients undergoing HD access had an AVF as their initial surgery with no difference in race/ethnicity. AVF type received differed by race, with Black patients twice as likely to undergo BAVF, which required two stages. Further studies are needed to identify the reasons for these differences.

RESUMEN

PURPOSE: Transcutaneous spinal cord stimulation (TSCS) is a novel neuromodulation modality developed to promote functional restoration in patients with neurological injury or disease. Previous pilot data suggest that lower urinary tract dysfunction (LUTD) due to stroke may be partially alleviated by TSCS. In this study, we examine the mechanism of this effect by evaluating bladder-related brain activity in patients before and after TSCS therapy and comparing it to healthy volunteers. MATERIALS AND METHODS: Patients who developed storage LUTD after a stroke and healthy volunteers without LUTD were recruited. Patients and healthy volunteers underwent simultaneous urodynamics and functional MRI. Patients then completed 24 biweekly sessions of TSCS and underwent another simultaneous urodynamics-functional MRI study. Clinical outcomes were assessed using validated questionnaires and voiding diary. RESULTS: Fifteen patients and 16 healthy volunteers completed the study. Following TSCS, patients exhibited increased blood-oxygen-level-dependent activity in areas including periaqueductal grey, the insula, the lateral prefrontal cortex, and motor cortex. Prior to TSCS therapy, healthy controls exhibited higher blood-oxygen-level-dependent activity in 17 regions, including multiple regions in the prefrontal cortex and basal ganglia. These differences were attenuated after TSCS with no frontal brain differences remaining between healthy volunteers and stroke participants who completed therapy. Neuroimaging changes were complemented by clinically significant improvements in questionnaire scores and voiding diary parameters. CONCLUSIONS: TSCS therapy modulated bladder-related brain activity, reducing differences between healthy volunteers and stroke patients with LUTD. These changes, alongside improved clinical outcomes, suggest TSCS as a promising approach for LUTD management.

RESUMEN

BACKGROUND: Standards for reporting surgical adverse events (AEs) vary widely within the scientific literature. Failure to adequately capture AEs hinders efforts to measure the safety of healthcare delivery and improve the quality of care. The aim of the present study is to assess the prevalence and typology of perioperative AE reporting guidelines among surgery and anesthesiology journals. MATERIALS AND METHODS: In November 2021, three independent reviewers queried journal lists from the SCImago Journal & Country Rank (SJR) portal (www.scimagojr.com), a bibliometric indicator database for surgery and anesthesiology academic journals. Journal characteristics were summarized using SCImago, a bibliometric indicator database extracted from Scopus journal data. Quartile 1 (Q1) was considered the top quartile and Q4 bottom quartile based on the journal impact factor. Journal author guidelines were collected to determine whether AE reporting recommendations were included and, if so, the preferred reporting procedures. RESULTS: Of 1409 journals queried, 655 (46.5%) recommended surgical AE reporting. Journals most likely to recommend AE reporting were: by category surgery (59.1%), urology (53.3%), and anesthesia (52.3%); in top SJR quartiles (i.e. more influential); by region, based in Western Europe (49.8%), North America (49.3%), and the Middle East (48.3%). CONCLUSIONS: Surgery and anesthesiology journals do not consistently require or provide recommendations on perioperative AE reporting. Journal guidelines regarding AE reporting should be standardized and are needed to improve the quality of surgical AE reporting with the ultimate goal of improving patient morbidity and mortality.

RESUMEN

INTRODUCTION: The accurate assessment and grading of adverse events (AE) is essential to ensure comparisons between surgical procedures and outcomes. The current lack of a standardized severity grading system may limit our understanding of the true morbidity attributed to AEs in surgery. The aim of this study is to review the prevalence in which intraoperative adverse event (iAE) severity grading systems are used in the literature, evaluate the strengths and limitations of these systems, and appraise their applicability in clinical studies. METHODS: A systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. PubMed, Web of Science, and Scopus were queried to yield all clinical studies reporting the proposal and/or the validation of iAE severity grading systems. Google Scholar, Web of Science, and Scopus were searched separately to identify the articles citing the systems to grade iAEs identified in the first search. RESULTS: Our search yielded 2957 studies, with 7 studies considered for the qualitative synthesis. Five studies considered only surgical/interventional iAEs, while 2 considered both surgical/interventional and anesthesiologic iAEs. Two included studies validated the iAE severity grading system prospectively. A total of 357 citations were retrieved, with an overall self/nonself-citation ratio of 0.17 (53/304). The majority of citing articles were clinical studies (44.1%). The average number of citations per year was 6.7 citations for each classification/severity system, with only 2.05 citations/year for clinical studies. Of the 158 clinical studies citing the severity grading systems, only 90 (56.9%) used them to grade the iAEs. The appraisal of applicability (mean%/median%) was below the 70% threshold in 3 domains: stakeholder involvement (46/47), clarity of presentation (65/67), and applicability (57/56). CONCLUSION: Seven severity grading systems for iAEs have been published in the last decade. Despite the importance of collecting and grading the iAEs, these systems are poorly adopted, with only a few studies per year using them. A uniform globally implemented severity grading system is needed to produce comparable data across studies and develop strategies to decrease iAEs, further improving patient safety.

RESUMEN

INTRODUCTION: Neurogenic bowel dysfunction is commonly encountered after a spinal cord injury (SCI), leading to a tremendous impact on quality of life (QOL). The neurogenic bowel dysfunction score (NBDS) is commonly used to measure the severity of bowel dysfunction and predict QOL. However, there is no comprehensive instrument to assess bowel-specific QOL for SCI patients. Instead, the Irritable Bowel Syndrome-Quality of Life (IBS-QOL) questionnaire evaluates the impact of bowel dysfunction on several aspects of QOL, although this questionnaire has not been validated for the SCI population. Motivated by the compelling need of instruments to accurately evaluate the QOL in patients who develope NBD after SCI, we aimed to assess the construct, content, and face validity of IBS-QOL in this population. METHODS: Adult SCI patients with at least 3 months after their injury were recruited from the outpatient clinic of a national rehabilitation hospital. Patients completed the NBDS and IBS-QOL via telephone interview or paper survey in the clinic. Content and face validity were assessed via interviews with professionals with expertise in providing chronic care for SCI, as well as a subgroup of patients. Construct validity was assessed using the hypotheses testing method. Internal consistency was assessed using Cronbach's ⍺. Factor analysis was performed to assess the dimensionality of the IBS-QOL in the SCI population. RESULTS: A total of 106 patients with a median age of 45.5 years (interquartile range: 21-79) participated in the study. The majority of the sample were men (n = 82, 77%) and had endured thoracolumbar injuries (n = 74, 71.2%). Twelve patients (seven English- and five Spanish speakers) and six professionals took part in content/face validation interviews. The median IBS-QOL total score was 15.91/100 (interquartile range: 4.55-33.14). IBS-QOL differentiated the subgroups of patients with severe bowel symptoms in terms of uneasiness, sweating, or headaches during bowel emptying (p = 0.0003), time spent on bowel emptying (p = 0.0065), flatus incontinence (p = 0.0076), and overall satisfaction with bowel function (p < 0.001), demonstrating its adequate construct validity. Interviews with the patients and professionals supported the comprehensiveness, comprehensibility, and relevance of IBS-QOL for assessment of bowel-related QOL in the SCI population. Item-level analysis of professional responses showed that 97% of questions were relevant to the construct and population of interest. Internal consistency analysis yielded a Cronbach's ⍺ of 0.9684. Exploratory factor analysis yielded six underlying factors which cumulatively accounted for 72.21% of the total variance, reflecting the dimensionality of bowel-related QOL in SCI population. DISCUSSION: IBS-QOL questionnaire is a comprehensive measure of bowel-related QOL which encompasses the concerns of SCI patients. Our findings support the content, face and construct validity of IBS-QOL as a measure of bowel-related QOL in SCI. Further studies are warranted to assess the reliability and responsiveness of IBS-QOL, and to evaluate its performance across different patient populations.

RESUMEN

OBJECTIVE: To report our experience and outcomes using a novel robotic technique for the simultaneous repair of rectovesical fistula (RVF) with vesicourethral anastomotic stricture (VUAS) after radical prostatectomy (RP). METHODS: Between 2019 and 2021, four consecutive patients who underwent robotic-assisted simultaneous repair of RVF with concurrent VUAS after RP were retrospectively reviewed. Baseline characteristics and perioperative outcomes were examined and reported. Complications were graded using the modified Clavien-Dindo classification system and the European Association of Urology Complications Panel Assessment and Recommendations. RESULTS: Four cases with a median age of 68.5 (63.3-72.3) years were treated. Interposition omentum flaps were used in all our cases. One case had perineal urethral mobilization to reach healthy urethral margins and tension-free vesicourethral anastomosis. Surgeries were uneventful, with no intraoperative complications reported. Median operative time, estimated blood loss, and length of hospital stay were 370 (291.3-453) minutes, 255 (175-262.5) mL, and 2.5 (2-3) days, respectively. Median Jackson-Pratt drains, Double-J stents and Foley catheter removal days were 6 (6-10), 38 (32-43), and 30 (27-41) days, respectively. No postoperative complications were reported. The median follow-up time was 16.25 (12-26) months, and no fistula recurrence was shown. CONCLUSION: Robotic-assisted laparoscopic repair could represent an effective approach for the simultaneous repair of RVF with concomitant VUAS. More studies and management standardization are needed to assess the role of the robotic platform in the simultaneous repair of RVF with VUAS after radical prostatectomy.

RESUMEN

Injury to the superior mesenteric artery (SMA) is a rare, underreported, and potentially devastating complication. This study aims to propose a systematic workup to describe how to prevent and manage SMA injury in a standardized stepwise manner. Three different instances of intraoperative injury to the SMA are described in an accompanying video. All three occurred when the SMA was misidentified as the left renal artery during left robotic radical nephrectomy. In the first case, the SMA was mistakenly identified as the renal artery, but after further dissection, the real renal artery was identified and SMA injury was prevented. In the second case, the SMA was clipped and the real left renal artery was subsequently identified, requiring clip removal. In the third case, the SMA was clipped and completely transected, requiring prompt repair by vascular surgery with a successful outcome. This study aims to propose a systematic workup to describe how to prevent and manage SMA injury in a standardized stepwise manner. The proper anatomic recognition of the SMA may prevent its injury. Intraoperative SMA injury should be promptly identified and repaired to avoid its devastating consequences.

RESUMEN

BACKGROUND: Obturator nerve injury (ONI) is an uncommon complication of pelvic surgery, usually reported in 0.2-5.7% of cases undergoing surgical treatment of urological and gynecological malignancies involving pelvic lymph node dissection (PLND). OBJECTIVE: To describe how an ONI may occur during robotic pelvic surgery and the corresponding management strategies. DESIGN, SETTING, AND PARTICIPANTS: We retrospectively analyzed video content on intraoperative ONI provided by robotic surgeons from high-volume centers. SURGICAL PROCEDURE: ONI was identified during PLND and managed according to the type of nerve injury. RESULTS AND LIMITATIONS: The management approach varies with the type of injury. Crush injury frequently occurs at an advanced stage of PLND. For a crush injury to the obturator nerve caused by a clip, management only requires its safe removal. Three situations can occur if the nerve is transected: (1) transection with feasible approximation and tension-free nerve anastomosis; (2) transection with challenging approximation requiring certain strategies for proper nerve anastomosis; and (3) transection with a hidden proximal nerve ending that may initially appear intact, but is clearly injured when revealed by further dissection. Each case has different management strategies with a common aim of prompt repair of the anatomic disruption to restore proper nerve conduction. CONCLUSIONS: ONI is a preventable complication that requires proper identification of the anatomy and high-risk areas when performing pelvic lymph node dissection. Prompt intraoperative recognition and repair using the management strategies described offer patients the best chance of recovery without sequelae. PATIENT SUMMARY: We describe the different ways in which the obturator nerve in the pelvic area can be damaged during urological or gynecological surgeries. This is a preventable complication and we describe how it can be avoided and different management options, depending on the type of nerve injury.

RESUMEN

BACKGROUND: Inguinal lymph node dissection (ILND) plays a crucial role in the oncological management of patients with melanoma, penile, and vulvar cancer. This study aims to systematically evaluate perioperative adverse events (AEs) in patients undergoing ILND and its reporting. METHODS: A systematic review was conducted according to PRISMA. PubMed, MEDLINE, Scopus, and Embase were queried to identify studies discussing perioperative AEs in patients with melanoma, penile, and vulvar cancer following ILND. RESULTS: Our search generated 3.469 publications, with 296 studies meeting the inclusion criteria. Details of 14.421 patients were analyzed. Of these studies, 58 (19.5%) described intraoperative AEs (iAEs) as an outcome of interest. Overall, 68 (2.9%) patients reported at least one iAE. Postoperative AEs were reported in 278 studies, combining data on 10.898 patients. Overall, 5.748 (52.7%) patients documented ≥1 postoperative AEs. The most reported ILND-related AEs were lymphatic AEs, with a total of 4.055 (38.8%) events. The pooled meta-analysis confirmed that high BMI (RR 1.09; p = 0.006), ≥1 comorbidities (RR 1.79; p = 0.01), and diabetes (RR 1.81; p = < 0.00001) are independent predictors for any AEs after ILND. When assessing the quality of the AEs reporting, we found 25% of studies reported at least 50% of the required criteria. CONCLUSION: ILND performed in melanoma, penile, and vulvar cancer patients is a morbid procedure. The quality of the AEs reporting is suboptimal. A more standardized AEs reporting system is needed to produce comparable data across studies for furthering the development of strategies to decrease AEs.

RESUMEN

OBJECTIVE: To report our experience and outcomes in minimally invasive management of rectourethral fistula (RUF). METHODS: From 2004 to 2021, 15 patients who underwent minimally invasive RUF repair by a single surgeon at 2 international institutions were retrospectively reviewed. Baseline demographic characteristics, perioperative, and postoperative data were collected. Complications were reported using the modified Clavien-Dindo Classification System and the European Association of Urology Complication Panel Assesment and Recommendations. Success was defined as complete resolution of fistula-related symptoms at 12-month follow-up along with confirmation of fistula closure by imaging or cystoscopy. Categorical variables were presented as frequencies and percentages whereas continuous variables were reported as median and quartiles. RESULTS: Fifteen male patients with a median age of 71 (64-79.2) years were treated. Four cases (26.6%) occurred postsurgery, 8 cases (53.3%) occurred after energy treatments, and 3 cases (20%) after surgery combined with an energy treatment modality. A robotic and laparoscopic approach was performed in 9 (60%) and 6 (40%) patients, respectively. No intraoperative complications were reported. Median operative time was 264 (217.5-341) minutes, estimated blood loss was 175 (137.5-200) mL, and the length of hospital stay was 4 days. Nine postoperative complications were reported. All patients were followed-up for 12 months with no recurrence reported. All patients reached our criteria for successful RUF repair. CONCLUSIONS: Minimally invasive surgery could represent an efficient way to manage RUF in selected patients. More studies and treatment standardization are needed to assess the role of minimally invasive surgery in the management of RUF.

RESUMEN

PURPOSE: The clinical, social, and economic impacts of neurogenic lower urinary tract dysfunction (NLUTD) on individuals and health care systems are thought to be immense, yet the true costs of care are unknown. The aims of this study are to illuminate the global costs related to the current state of care for NLUTD. MATERIALS AND METHODS: A systematic review of the literature was performed using MEDLINE, the National Health Service Economic Evaluation Database, and the Cochrane Specialized Urology and Incontinence Registers. Studies reporting the health care costs of NLUTD were identified. All steps of the review were performed by 2 independent reviewers. Costs were converted to 2022 U.S. dollars and reported for different categories of services. RESULTS: A total of 13 studies were included in the final review (12 from high-income economy, and 1 from an upper-middle-income economy). Routine maintenance care varied notably across studies in terms of included services. Annual supportive costs ranged from $2,039.69 to $12,219.07 with 1 study estimating lifetime costs of $112,774 when complications were considered. There were limited data on the costs of care from the patient's perspective. However, catheters and absorbent aids were estimated to be among the costliest categories of expenditure during routine care. More invasive and reconstructive treatments were associated with significant costs, ranging between $18,057 and $55,873. CONCLUSIONS: NLUTD incurs a variety of health care expenditures ranging from incontinence supplies to hospitalizations for management of complications and leads to a significant burden for health care systems over the patient's lifetime. Approaches to NLUTD that focus on functional rehabilitation and restoration, rather than on management of complications, may prove to be a less costly and more effective alternative.

RESUMEN

INTRODUCTION: Body mass index (BMI) has been established as an independent risk factor for complications after abdominal hernia repairs. While various thresholds have been proposed, there is no consensus for an ideal BMI for elective hernia repair. OBJECTIVE: To identify the BMI threshold at which risk for hernia recurrence is significantly increased in patients undergoing ventral and incisional hernia repair. METHODS: This retrospective review of medical records included patients who underwent ventral or incisional hernia repairs from 2014 to 2020 at a single institution. Patients with hernia defects ≥4 cm were included. The primary outcome measure was hernia recurrence. Classification and Regression Tree (CART) analysis was used to determine the BMI threshold for recurrence. Bivariate and multivariate analyses were used to validate the threshold and to evaluate factors associated with recurrence. RESULTS: Of the 175 patients included, 9.1% had a recurrence. Classification and Regression Tree analysis identified BMI 35.3 kg/m2 as the critical threshold for hernia recurrence. In bivariate analysis, compared to patients who had no recurrence, patients with recurrence were more likely to have cirrhosis (12.5% vs 0%, P = .008), incarcerated hernias (75.0% vs 31.4%, P = .001), urgent surgery (75.0% vs 22.0%, P = <.001), biologic and no mesh use (25.0% vs 6.4% and 12.5% vs 5.7%, P = .012), and BMI >35.3 kg/m2 (75.0% vs 25.8%, P < .001). In multivariate regression, only BMI >35.3 kg/m2 was associated with recurrence [OR: 20.58 (95% CI: 2.17-194.87), P = .008]. CONCLUSION: Body mass index >35.3 kg/m2 was the only independent factor associated with hernia recurrence. This highlights the importance of determining a BMI threshold for patients undergoing ventral or incisional hernia repair.

RESUMEN

INTRODUCTION AND HYPOTHESIS: Vesicovaginal fistula (VVF) is an abnormal communication between the bladder and the vagina. Complex fistulae include those after failed repair attempts, radiotherapy, measuring ≥ 2 cm, located in the trigone, or with concomitant ureteric strictures or fistulae. We aimed to describe a technique for the robotic repair of a complex VVF using a vaginal cuff flap. METHODS: A 56-year-old woman with a history of ovarian debulking surgery and radiotherapy underwent repair for VVF and rectovaginal fistula. In lithotomy, cystoscopy was performed for fistulous tract cannulation. Port placement, extensive adhesiolysis, and robot docking followed. The vaginal apex was dissected, the VVF excised, and the bladder closed. The rectum was separated from the posterior vaginal wall, the rectovaginal fistula excised, and the rectum closed. A vaginal cuff flap was harvested and interposed between the bladder and the vagina. RESULTS: Operative time was 9 h, estimated blood loss was 300 cc, and no intraoperative complications occurred. The patient was discharged on postoperative day 8. Further management included 37 sessions in a hyperbaric chamber and a transvesical endoluminal bladder closure 10 months after the initial surgery. Follow-up at 30 months shows no fistula recurrence. CONCLUSIONS: Vaginal cuff flaps represent a feasible interposition tissue in patients with hysterectomy for managing complex VVF in the case of omentum unavailability.

RESUMEN

Recent advances in ultrasonography (US) technology established modalities, such as Doppler-US, HistoScanning, contrast-enhanced ultrasonography (CEUS), elastography, and micro-ultrasound. The early results of these US modalities have been promising, although there are limitations including the need for specialized equipment, inconsistent results, lack of standardizations, and external validation. In this review, we identified studies evaluating multiparametric ultrasonography (mpUS), the combination of multiple US modalities, for prostate cancer (PCa) diagnosis. In the past 5 years, a growing number of studies have shown that use of mpUS resulted in high PCa and clinically significant prostate cancer (CSPCa) detection performance using radical prostatectomy histology as the reference standard. Recent studies have demonstrated the role mpUS in improving detection of CSPCa and guidance for prostate biopsy and therapy. Furthermore, some aspects including lower costs, real-time imaging, applicability for some patients who have contraindication for magnetic resonance imaging (MRI) and availability in the office setting are clear advantages of mpUS. Interobserver agreement of mpUS was overall low; however, this limitation can be improved using standardized and objective evaluation systems such as the machine learning model. Whether mpUS outperforms MRI is unclear. Multicenter randomized controlled trials directly comparing mpUS and multiparametric MRI are warranted.

RESUMEN

Radical prostatectomy is the gold standard in patients that are surgical candidates with localized prostate cancer. While most postoperative urine leaks are from vesico-urethral anastomosis, urologists must be aware that a small percentage of patients may have a urine leak from other sites that may have been inadvertently injured during the procedure. We propose a systematic workup to evaluate the source of the urinary leak as well as appropriate management of such injuries. The mid-ureter can be injured during lymph node dissection. The distal ureter is at risk of injury when performing the Montsouris approach. The posterior bladder neck dissection can at times be challenging. If not careful, one can easily cause an injury to the trigone and/or ureteral orifices. The most common site of leak is at the vesico-urethral anastomosis due to a non-watertight closure. The management of intraoperatively detected ureteral injuries require placement of a ureteral stent. The location, severity and type of injury determine the reconstruction required to fix it. Postoperatively urine leak can be frequently detected when assessing the pelvic drain, and imaging such as CT Urogram with a cystogram phase may be helpful in the diagnosis. Urine leak after robotic-assisted laparoscopic radical prostatectomy remains a rare complication, sometimes the diagnosis can be challenging, and management varies depending on the site and severity of injury.

RESUMEN

Due to the ongoing coronavirus disease 2019 (COVID-19) pandemic, almost all residency programs have adopted virtual interviewing for the National Residency Matching Program® (NRMP) or The Match® 2021. Hence, applicants have had to adapt quickly to this process, since the interviewers and the applicants were mostly inexperienced regarding this process. To date, program directors have had a successful experience on this new modality, and since the pandemic continues to limit in-person meetings and given the benefits that virtual interviews provide in terms of transportation, booking, and cost, there is a high chance that interviews for The Match 2022 will also be conducted in the same, virtual way. In light of this, we performed a review of the literature by using PubMed, Embase, Scopus, and other online resources to analyze certain critical aspects and offer recommendations for residency and fellowship applicants to improve their performance in virtual interviews. Despite the current surge of virtual interviewing in today's technology-driven era, virtual interviewing programs for residency and fellowship candidates selection are still in their infancy. We have learned that applicants can control certain aspects such as technology, settings, dress code, and behavior so that they can tailor their experience to make it more favorable and fulfilling. Ensuring proper preparation in terms of the variables that can influence the virtual experience is key for a successful interview.
