HemoCue Hb-801 Provides More Accurate Hemoglobin Assessment in Blood Donors Than OrSense NBM-200. Transfus Med Rev 2024; 38:150826. [PMID: 38581862 DOI: 10.1016/j.tmrv.2024.150826] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 03/11/2024] [Accepted: 03/14/2024] [Indexed: 04/08/2024]
Abstract
Hemoglobin levels are commonly assessed to prevent causing or worsening of anemia in prospective blood donors. We compared head-to-head the accuracy of different technologies for measuring hemoglobin suitable for use in mobile donation units. We included 144 persons donating platelets at the Central Institute for Blood Transfusion and Immunology in Innsbruck, Austria. Hemoglobin levels were measured in venous blood using the portable hemoglobinometer HemoCue Hb-801 and noninvasively using OrSense NBM-200, and compared to values obtained with the Sysmex XN-430, an automated hematology analyzer employing the sodium lauryl sulphate method, which is broadly used as reference method in everyday clinical practice. Mean age of participants was 34.2 years (SD 13.0); 34.0% were female. Hemoglobin values measured with HemoCue were more strongly correlated with the Sysmex XN-430 (r = 0.90 [95% CI: 0.87-0.93]) than measured with OrSense (r = 0.49 [0.35-0.60]). On average, HemoCue overestimated hemoglobin by 0.40 g/dL (0.31-0.48) and OrSense by 0.75 g/dL (95% CI: 0.54-0.96). When using OrSense, we found evidence for higher overestimation at higher hemoglobin levels (proportional bias) specifically in females but not in males (Pdifference = .003). Sensitivity and specificity for classifying donors according to the hemoglobin donation thresholds were 99.2% (95% CI: 95.3%-100.0%) and 43.8% (23.1%-66.8%) for HemoCue vs 95.3% (89.9%-98.0%) and 12.5% (2.2%-37.3%) for OrSense. Areas under the receiver operating characteristic curves were higher using HemoCue vs OrSense both in females (0.933 vs 0.547; P = .044) and males (0.948 vs 0.628; P < .001). HemoCue Hb-801 measures hemoglobin more accurately than OrSense NBM-200 in the setting of mobile blood donation units. Our findings are particularly relevant for females, having in mind that anemia is more prevalent in females than in males.

Crosstalk between purinergic receptor P2Y 11 and chemokine receptor CXCR7 is regulated by CXCR4 in human macrophages. Cell Mol Life Sci 2024; 81:132. [PMID: 38472446 DOI: 10.1007/s00018-024-05158-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Revised: 01/22/2024] [Accepted: 02/05/2024] [Indexed: 03/14/2024]
Abstract
P2Y11 is a G protein-coupled ATP receptor that activates IL-1 receptor (IL-1R) in a cyclic AMP dependent manner. In human macrophages, P2Y11/IL-1R crosstalk with CCL20 as a prime target is controlled by phosphodiesterase 4 (PDE4), which mediates breakdown of cyclic AMP. Here, we used gene expression analysis to identify activation of CXCR4 and CXCR7 as a hallmark of P2Y11 signaling. We found that PDE4 inhibition with rolipram boosts P2Y11/IL-1R-induced upregulation of CXCR7 expression and CCL20 production in an epidermal growth factor receptor dependent manner. Using an astrocytoma cell line, naturally expressing CXCR7 but lacking CXCR4, P2Y11/IL-1R activation effectively induced and CXCR7 agonist TC14012 enhanced CCL20 production even in the absence of PDE4 inhibition. Moreover, CXCR7 depletion by RNA interference suppressed CCL20 production. In macrophages, the simultaneous activation of P2Y11 and CXCR7 by their respective agonists was sufficient to induce CCL20 production with no need of PDE4 inhibition, as CXCR7 activation increased its own and eliminated CXCR4 expression. Finally, analysis of multiple CCL chemokines in the macrophage secretome revealed that CXCR4 inactivation and CXCR7 activation selectively enhanced P2Y11/IL-1R-mediated secretion of CCL20. Altogether, our data establish CXCR7 as an integral component of the P2Y11/IL-1R-initiated signaling cascade and CXCR4-associated PDE4 as a regulatory checkpoint.

ESRU-ESU-YAU_UROTECH Survey on Urology Residents Surgical Training: Are We Ready for Simulation and a Standardized Program? EUR UROL SUPPL 2024; 61:18-28. [PMID: 38384440 PMCID: PMC10879935 DOI: 10.1016/j.euros.2023.12.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/07/2023] [Indexed: 02/23/2024] Open
Abstract
Background Currently, the landscape of surgical training is undergoing rapid evolution, marked by the initial implementation of standardized surgical training programs, which are further facilitated by the emergence of new technologies. However, this proliferation is uneven across various countries and hospitals. Objective To offer a comprehensive overview of the existing surgical training programs throughout Europe, with a specific focus on the accessibility of simulation resources and standardized surgical programs. Design setting and participants A dedicated survey was designed and spread in May 2022 via the European Association of Urology (EAU) mail list, to Young Urologist Office (YUO), Junior membership, European Urology Residents Education Program participants between 2014 and 2022, and other urologists under 40 yr, and via the EAU Newsletter. Intervention A 64-item, online-based survey in accordance with the Checklist for Reporting Results of Internet E-Surveys (CHERRIES) using the platform of Survey Monkey (Portland, OR, USA) was realized. Outcome measurements and statistical analysis The study involved an assessment of the demographic characteristics. Additionally, it explored the type of center, availability of various surgical approaches, presence of training infrastructure, participation in courses, organization of training, and participants' satisfaction with the training program. The level of satisfaction was evaluated using a Likert-5 scale. The subsequent sections delved into surgical training within the realms of open, laparoscopic, robotic, and endoscopic surgery, each explored separately. Finally, the investigation encompassed the presence of a structured training course and the availability of a duly validated final evaluation process. Results and limitations There were 375 responders with a completion rate of 82%. Among them, 75% were identified as male, 50.6% were young urologists, 31.7% were senior residents, and 17.6% were junior residents. A significant majority of participants (69.6%) were affiliated with academic centers. Regarding the presence of dry lab training facilities, only 50.3% of respondents indicated its availability. Among these centers, 46.7% were primarily focused on laparoscopy training. The availability of virtual and wet lab training centers was even more limited, with rates of 31.5% and 16.2%, respectively. Direct patient involvement was reported in 80.5% of cases for open surgery, 58.8% for laparoscopy, 25.0% for robotics, and 78.6% for endourology. It is worth noting that in <25% of instances, training followed a well-defined standardized program comprising both preclinical and clinical modular phases. Finally, the analysis of participant feedback showed that 49.7% of respondents expressed a satisfaction rating of either 4 or 5 points with respect to the training program. The limitations of our study include the low response rate, predominance of participants from academic centers, and absence of responses from individuals not affiliated with the EAU network. Conclusions The current distribution of surgical training centers falls short of ensuring widespread access to standardized training programs. Although dry lab facilities are relatively well spread, the availability of wet lab resources remains restricted. Additionally, it appears that many trainees' initial exposure to surgery occurs directly with patients. There is a pressing need for continued endeavors to establish uniform training routes and assessment techniques across various surgical methodologies. Patient summary Nowadays, the surgical training landscape is heterogeneous across different countries. The implementation of a standardized training methodology to enhance the overall quality of surgical training and thereby improving patient outcomes is needed.

Discrimination, Reliability, Sensitivity, and Specificity of Robotic Surgical Proficiency Assessment With Global Evaluative Assessment of Robotic Skills and Binary Scoring Metrics: Results From a Randomized Controlled Trial. ANNALS OF SURGERY OPEN 2023; 4:e307. [PMID: 37746611 PMCID: PMC10513364 DOI: 10.1097/as9.0000000000000307] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Accepted: 06/03/2023] [Indexed: 09/26/2023] Open
Abstract
Objective To compare binary metrics and Global Evaluative Assessment of Robotic Skills (GEARS) evaluations of training outcome assessments for reliability, sensitivity, and specificity. Background GEARS-Likert-scale skills assessment are a widely accepted tool for robotic surgical training outcome evaluations. Proficiency-based progression (PBP) training is another methodology but uses binary performance metrics for evaluations. Methods In a prospective, randomized, and blinded study, we compared conventional with PBP training for a robotic suturing, knot-tying anastomosis task. Thirty-six surgical residents from 16 Belgium residency programs were randomized. In the skills laboratory, the PBP group trained until they demonstrated a quantitatively defined proficiency benchmark. The conventional group were yoked to the same training time but without the proficiency requirement. The final trial was video recorded and assessed with binary metrics and GEARS by robotic surgeons blinded to individual, group, and residency program. Sensitivity and specificity of the two assessment methods were evaluated with area under the curve (AUC) and receiver operating characteristics (ROC) curves. Results The PBP group made 42% fewer objectively assessed performance errors than the conventional group (P < 0.001) and scored 15% better on the GEARS assessment (P = 0.033). The mean interrater reliability for binary metrics and GEARS was 0.87 and 0.38, respectively. Binary total error metrics AUC was 97% and for GEARS 85%. With a sensitivity threshold of 0.8, false positives rates were 3% and 25% for, respectively, the binary and GEARS assessments. Conclusions Binary metrics for scoring a robotic VUA task demonstrated better psychometric properties than the GEARS assessment.

Abstract
Ureteropelvic junction obstruction (UPJO) is a congenital or acquired functionally significant impairment of urinary transport from the renal pelvis to the ureter. Congenital UPJO typically results from intrinsic disease such as the presence of an aperistaltic segment of the ureter, aberrant vessels or kidney abnormalities. Rare conditions can sometimes mimic an UPJO. We present a case of an 86-year-old woman with a UPJO diagnosed on CT. The patient was counseled on treatment options and elected to undergo a left uretherorenoscopy (URS) plus left laparoscopic pyeloplasty. The definitive histopathologic diagnosis was perinephric myxoid pseudotumor of fat, an extremely rare neoplasm, mass-forming. To the best of our knowledge, this is the first known case of a pseudotumor of fat causing UPJO. 6-month follow-up showed neither recurrence nor residual UPJO. We describe a rare presentation of extrinsic perinephric myxoid pseudotumor of fat causing UPJ obstruction. In elderly patients with no history of malignancy, UPJ obstruction can occur because of atypical masses.

Abstract
OBJECTIVE To determine whether proficiency-based progression (PBP) training leads to better robotic surgical performance compared to traditional training (TT), given that the value of PBP training for learning robotic surgical skills is unclear. MATERIALS AND METHODS The PROVESA trial is a multicentric, prospective, randomized and blinded clinical study comparing PBP training with TT for robotic suturing and knot-tying anastomosis skills. A total of 36 robotic surgery-naïve junior residents were recruited from 16 training sites and 12 residency training programmes. Participants were randomly allocated to metric-based PBP training or the current standard of care TT, and compared at the end of training. The primary outcome was percentage of participants reaching the predefined proficiency benchmark. Secondary outcomes were the numbers of procedure steps and errors made. RESULTS Of the group that received TT, 3/18 reached the proficiency benchmark versus 12/18 of the PBP group (i.e. the PBP group were ~10 times as likely to demonstrate proficiency [P = 0.006]). The PBP group demonstrated a 51% reduction in number of performance errors from baseline to the final assessment (18.3 vs 8.9). The TT group demonstrated a marginal improvement (15.94 vs 15.44) in errors made. CONCLUSIONS The PROVESA trial is the first prospective randomized controlled trial on basic skills training in robotic surgery. Implementation of a PBP training methodology resulted in superior surgical performance for robotic suturing and knot-tying anastomosis performance. Compared to TT, better surgical quality could be obtained by implementing PBP training for basic skills in robotic surgery.

Abstract
We evaluated the feasibility and impact on short- and long-term functional outcomes of very early catheter removal on postoperative day (POD) 2 after robot-assisted radical prostatectomy (RARP). To the best of our knowledge, this is the first multisurgeon study with the largest cohort on very early (POD 2) catheter removal after RARP with follow-up of >1 yr. In 255/369 patients (69%) treated with RARP ± pelvic lymph node dissection, the catheter was removed on POD 2. Among the 255 patients, 33 (13%) required recatheterisation because of acute urinary retention after catheter removal. Of these 33 patients, five (2%) also experienced anastomotic leakage after catheter removal. The early (≤3 mo) urinary continence rate was 67% and the median time to urinary continence recovery was 1 mo. After median follow-up of 18 mo (interquartile range 13-24), 236 patients (88%) were continent. No anastomotic strictures occurred. Our observations confirm the feasibility and safety of POD 2 catheter removal after RARP and support its adoption for selected patients. PATIENT SUMMARY: After removal of the prostate for cancer, patients have a urinary catheter inserted. We investigated whether earlier removal of the catheter affects long-term urinary continence. The results show that it may be safe to remove the catheter on postoperative day 2 for selected patients.

Abstract
Objective Kidney cancers account for approximately 2% of all newly diagnosed cancer in 2020. Among the primary treatment options for kidney cancer, urologist may choose between radical or partial nephrectomy, or ablative therapies. Nowadays, robotic-assisted partial nephrectomy (RAPN) for the management of renal cancers has gained popularity, up to being considered the gold standard. However, RAPN is a challenging procedure with a steep learning curve. Methods In this narrative review, different imaging technologies used to guide and aid RAPN are discussed. Results Three-dimensional visualization technology has been extensively discussed in RAPN, showing its value in enhancing robotic-surgery training, patient counseling, surgical planning, and intraoperative guidance. Intraoperative imaging technologies such as intracorporeal ultrasound, near-infrared fluorescent imaging, and intraoperative pathological examination can also be used to improve the outcomes following RAPN. Finally, artificial intelligence may play a role in the field of RAPN soon. Conclusion RAPN is a complex surgery; however, many imaging technologies may play an important role in facilitating it.

Abstract
BackgroundFibromyalgia and ME/CFS are multifaceted conditions with overlapping symptoms(1); the pathoaetiological mechanisms are complex and debated(2), however there is a strong association with features of hereditary disorders of connective tissue (hypermobility) and autonomic and inflammatory abnormalities (1,2).ObjectivesTo determine potential autonomic and inflammatory mechanisms of pain and fatigue in fibromyalgia and ME/CFSMethodsAfter excluding participants with WCC higher than 10 (suggesting acute infection) baseline markers of inflammation (CRP and ESR) were available for 60 patients with confirmed diagnoses of Fibromyalgia and/ or ME/CFS and 23 matched controls. Participants then underwent full research diagnostic evaluation including a hypermobility assessment(1) and autonomic challenge (60 degree head up tilt, ISRCTN78820481). Subjective pain and fatigue were assessed before and after challenge (VAS). Linear regression models were used to explore predictors, with adjustment for confounders as appropriate. Mediation analyses (looking for mechanistic effects) were conducted according to the method of Hayes (3) and mediation considered significant if bootstrapped confidence intervals of the estimated indirect effect did not cross zero. In these mediation analyses predictor variable was group membership (patient or control), outcome variable was change in 1)pain and 2)fatigue induced by challenge and mediatiors 1)no of connective tissue features in hypermobility diagnostic criteria endorsed by participant; 2)baseline inflammatory markers.ResultsESR and CRP were significantly higher in patients rather than controls, even after correcting for BMI, age and sex (B=5.15, t=2.05, p=0.044; B=1.77, t=2.15, p=0.044 respectively). Adjusted ESR and CRP correlated with both subjective fatigue (B=0.44, t=2.09, p=0.04; B=1.63, t=2.60, p=0.011) and pain severity (B=0.13, t=2.51, p=0.014; B=0.45, t=3.01, p=0.004) at baseline. Autonomic challenge amplified pain (B=14.20, t=2.87, p=0.005) and fatigue (B=31.48, t=5.95, p=<0.001) in patients to a significantly greater degree than controls, controlling for baseline levels. Baseline ESR and CRP also predicted challenge-induced increase in fatigue (B=0.78, t=370, p=<0.001; B=1.91, t=3.36, p=<0.001) and ESR challenge-induced increases in pain (B=0.46, t=2.35, p=0.021).Mediation analysis demonstrated that number of connective tissue features expressed in hypermobility criteria mediated the degree to which subjective pain was increased by the autonomic challenge (Bootstraped 95% CI of indirect effect do not cross zero, 0.1572 – 6.8171). ESR mediated the degree to which subjective fatigue was increased by the autonomic challenge (Bootstraped 95% CI of indirect effect do not cross zero,0.7541 – 7.3888).ConclusionTo our knowledge this is the first study to directly explore autonomic and inflammatory mechanisms of pain and fatigue in a combined population of Fibromyalgia and ME/CFS. This study this adds to the evidence-base of baseline inflammatory abnormalities in fibromyalgia and ME/CFS. It highlights their potential role in predicting symptom severity and their potential mechanistic role in autonomic induced pain and fatigue, suggesting future treatment strategies.References[1]Eccles JA, Thompson B, Themelis K, Amato ML, Stocks R, Pound A, et al.

Abstract
OBJECTIVES Radical cystectomy (RC) represents the gold standard treatment for high-risk bladder cancer. Despite evidence suggesting that surgical experience correlates with perioperative and oncologic outcomes of robot-assisted RC (RARC), validated tools to assess its quality objectively are lacking. We aimed to evaluate the impact of RC-Pentafecta (absence of early major complications, absence of urinary diversion related sequelae at ≤12 months, absence of soft tissue surgical margins, ≥16 lymph nodes at final pathology and absence of clinical recurrence at ≤12 months) on oncological outcomes and the role of surgical experience on its achievement. MATERIALS AND METHODS We retrospectively evaluated 366 patients undergoing RARC with intracorporeal urinary diversion in a single tertiary centre with a minimum of 1 year follow-up. Surgeries were performed using the DaVinci Xi system according to a previously described technique. Kaplan-Meier curves were used to investigate 5-years overall survival and cancer specific mortality-free survival (CSS) according to RC-Pentafecta achievement. Multivariable Cox's regressions were performed to evaluate the impact of RC-Pentafecta on overall mortality. Multivariable logistic regressions were performed to explore the effect of surgical experience on RC-pentafecta achievement. Locally weighted scatterplot smoother function was used to graphically explore this relationship. RESULTS Patients achieving RC-Pentafecta showed higher 5-year overall survival (71.8% vs. 59.6%, P < 0.001) and CSS (84% vs. 71%, P < 0.001) when compared with patients not achieving it. At multivariable Cox's regression, RC-Pentafecta achievement (HR 0.57, P = 0.03), positive surgical margins (HR 2.48, P = 0.002), pN+ (HR 2.23, P = 0.002), pT≥3 (HR 1.71, P = 0.04) and current smoking status (HR 2.4, P = 0.006) were significant predictors of overall mortality. At multivariable logistic regression surgical experience (OR 1.2, P < 0.001), age (OR 0.93, P = 0.04), previous prostate surgery (OR 0.7, P = 0.02) and pT≥3 (OR 0.8, P = 0.03) were independent predictors of RC-Pentafecta achievement. A linear relationship between surgical experience and RC-Pentafecta achievement, without reaching a plateau, was observed. CONCLUSIONS RC-Pentafecta is a valuable tool to assess surgical quality of RARC and the experience of the center where the surgery is performed and may be used to identify "referral" centers for treatment of high-risk bladder cancer.

Does quality assured eLearning provide adequate preparation for robotic surgical skills; a prospective, randomized and multi-center study. Int J Comput Assist Radiol Surg 2022; 17:457-465. [PMID: 34997525 PMCID: PMC8740863 DOI: 10.1007/s11548-021-02545-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Accepted: 12/10/2021] [Indexed: 11/26/2022]
Abstract
Purpose In particular after the onset of the COVID-19 pandemic, there was a precipitous rush to implement virtual and online learning strategies in surgery and medicine. It is essential to understand whether this approach is sufficient and adequate to allow the development of robotic basic surgical skills. The main aim of the authors was to verify if the quality assured eLearning is sufficient to prepare individuals to perform a basic surgical robotic task.
Methods A prospective, randomized and multi-center study was conducted in September 2020 in the ORSI Academy, International surgical robotic training center. Forty-seven participants, with no experience but a special interest in robotic surgery, were matched and randomized into four groups who underwent a didactic preparation with different formats before carrying out a robotic suturing and anastomosis task. Didactic preparation methods ranged from a complete eLearning path to peer-reviewed published manuscripts describing the suturing, knot tying and task assessment metrics. Results The primary outcome was the percentage of trainees who demonstrated the quantitatively defined proficiency benchmark after learning to complete an assisted but unaided robotic vesico-urethral anastomosis task. The quantitatively defined benchmark was based on the objectively assessed performance (i.e., procedure steps completed, errors and critical errors) of experienced robotic surgeons for a proficiency-based progression (PBP) training course. None of the trainees in this study demonstrated the proficiency benchmarks in completing the robotic surgery task. Conclusions PBP-based e-learning methodology is an effective training method avoiding critical errors in the suturing and knotting task. Quality assured online learning is insufficient preparation for robotic suturing and knot tying anastomosis skills. Trial registration ClinicalTrials.gov Identifier: NCT04541615.

Abstract
INTRODUCTION Ectopic kidney is a rare anatomic variant with an incidence of about 1 in 900. Renal stones can pose a challenge when a standard approach is not possible. Laparoscopic-assisted endourologic procedure can be a feasible and safe choice. CASE REPORT AND LITERATURE REVIEW We present a case of 32 years old man with spastic quadriplegia, megacolon and pelvic kidney undergoing intervention of laparoscopic-assisted Mini ECIRS for staghorn stone of the left pelvic kidney. To the best of our knowledge, only 59 cases are reported in the literature concerning laparoscopically assisted encdourologic treatment which seems a feasible, safe and adaptable technique in selected complex cases. CONCLUSION Laparoscopic-assisted mini ECIRS is a viable option for the treatment of ectopic kidney stones. This technique should be considered when anatomical anomalies are encountered, to avoid puncture-related complications.

Simplified PADUA renal (SPARE) nephrometry score validation and long-term outcomes after robot-assisted partial nephrectomy. Urol Oncol 2021; 40:65.e1-65.e9. [PMID: 34824015 DOI: 10.1016/j.urolonc.2021.09.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Revised: 09/20/2021] [Accepted: 09/27/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND International guidelines suggest the use of anatomic scores to predict surgical outcomes after partial nephrectomy (PN). We aimed at validating the use of Simplified PADUA Renal (SPARE) nephrometry score in robot-assisted PN (RAPN). MATERIALS AND METHODS Three hundred and sixty-eight consecutive RAPN patients were included. Primary endpoints were overall complications, postoperative acute kidney injury (AKI) and TRIFECTA achievement. Secondary endpoint was estimated glomerular filtration rate (eGFR) decrease at last follow-up. Multivariable logistic and linear regression models were used. RESULTS Of 368 patients, 229 (62%) vs. 116 (31%) vs. 23 (6.2%) harboured low- vs. intermediate- vs. high-risk renal mass, according to SPARE classification. SPARE score predicted higher risk of overall complications (Odds ratio [OR]: 1.23, 95%CI 1.09-1.39; P < 0.001), and postoperative AKI (OR: 1.20, 95%CI 1.08-1.35; P < 0.01). Moreover, SPARE score was associated with lower TRIFECTA achievement (OR: 0.89, 95%CI 0.81-0.98; P = 0.02). Predicted accuracy was 0.643, 0.614 and 0.613, respectively. After a median follow-up of 40 (IQR: 21-66) months, eGFR decrease ranged from -7% in low-risk to -17% in high-risk SPARE. CONCLUSIONS SPARE scoring system predicts surgical success in RAPN patients. Moreover, SPARE score is associated with eGFR decrease at long-term follow-up. Thus, the adoption of SPARE score to objectively assess tumor complexity prior to RAPN may be preferable.

Abstract
Worldwide, we have witnessed an expansion of robot-assisted laparoscopic surgery (RALS) and thanks to the global adoption of high-resolution diagnostic imaging technologies, an increased incidence of newly diagnosed prostatic, renal and bladder cancers has been recorded with concurrent second primary urological cancer diagnoses increasing by 1.5%. Diverse authors have reported their findings concerning synchronous multi-visceral malignances robotic treatment within the scientific literature. The aim of this study is to comprehensively review all reported articles describing concurrent upper and lower RALS using a singular robotic port scheme within the same intervention for renal malignances and concomitant prostatic or bladder cancers. To the best of our knowledge and vigorous literature search, this is the first study that comprehensively evaluates and reports all combined upper and lower urinary tract surgeries published so far. In carefully selected patients, thanks to multidisciplinary preoperative assessment and surgical planning a combined robotic approach can reduce the morbidity, complications, hospital admissions and the overall length of hospitalization.

Abstract
BACKGROUND The aim of this study is to investigate the prevalence of localized intraoral neuropathic pain in a cluster of patients who reported the involvement of gingival site as only clinical manifestation of dysesthesia, analysing type and distribution of symptoms. MATERIAL AND METHODS Burning mouth syndrome (BMS) patients were enrolled in the study. Patients were screened through laboratory test and a conventional oral examination with periodontal chart. A questionnaire to collect data on symptoms, oral site involved, quality of sleep, anxiety was submitted to all the patients. RESULTS A total of 236 patients were recruited. Seventy-six patients (32.2%) presented generalized type, whereas 160 (67.8%) had localized type. In the localized BMS group, the gingiva was involved in 70 patients and in 33 of these it was the only site involved. In the gingival subgroup, 35 patients reported burning, 29 pain and 24 xerostomia. CONCLUSIONS To best our knowledge, this study is the first that analyses gingival involvement as the only site in BMS and it could encourage further investigations to understand the etiopathogenesis of gingival BMS.

Abstract
Purpose: To summarize the scientific published literature on new robotic surgical platforms with potential use in the urological field, reviewing their evolution from presentation until the present day. Our goal is to describe the current characteristics and possible prospects for these platforms. Materials and Methods: A nonsystematic search of the PubMed, Cochrane library's Central, EMBASE, MEDLINE, and Scopus databases was conducted to identify scientific literature about new robotic platforms other than the Da Vinci® system, reviewing their evolution from inception until December 2020. Only English language publications were included. The following keywords were used: "new robotic platforms," "Revo-I robot," "Versius robot," and "Senhance robot." All relevant English-language original studies were analyzed by one author (R.F.) and summarized after discussion with an independent third party (E.M., S.Y., S.P., and M.A.). Results: Since 1995, Intuitive Surgical, Inc., with the Da Vinci surgical system, is the leading company in the robotic surgical market. However, Revo-I®, Versius®, and Senhance® are the other three platforms that recently appeared on the market with available articles published in peer-reviewed journals. Among these three new surgical systems, the Senhance robot has the most substantial scientific proof of its capacity to perform minimally invasive urological surgery and as such, it might become a contender of the Da Vinci robot. Conclusions: The Da Vinci surgical platform has allowed the diffusion of robotic surgery worldwide and showed the different advantages of this type of technique. However, its use has some drawbacks, especially its price. New robotic platforms characterized by unique features are under development. Of note, they might be less expensive compared with the Da Vinci robotic system. We found that these new platforms are still at the beginning of their technical and scientific validation. However, the Senhance robot is in a more advanced stage, with clinical studies supporting its full implementation.

Abstract
BACKGROUND Prostate cancer is the most commonly diagnosed neoplasm in men. From the introduction of PSA testing, an increasing number of men undergoes prostate biopsy (PBX). While the physical side effects of PBx have been well investigated, its psychological impact has been under-evaluated. AIM The aim of our study is to investigate the presence of psychological distress (anxiety and depression) in patients waiting for histopathological results after prostate biopsy (PBx). METHODS From February to April 2019, 51 consecutive patients undergoing prostate biopsies at our institution were included. Age, PSA, DRE, familiarity for prostate cancer, number of previous biopsies, type of anesthesia, number of cores were recorded. All patients filled the Hospital Anxiety and Depression Scale (HADS), a psychometric Likert-scale questionnaire, before receiving the histopathological results of their PBx. RESULTS The prevalence of psychological distress among patients awaiting histopathologic results is 41% (21/51 patients), with anxiety being the main component of their distress. On multivariate analysis, PSA, family history, and repeat biopsy were significantly associated with anxiety and depression. CONCLUSION Patients undergoing PBx experience a burden of psychological distress waiting for histopathologic results, especially anxiety. Appropriate counseling should be offered to patients at high risk of developing psychological distress after PBx. Future goals would include technological improvements to shorten the time between biopsy and definitive results.

Abstract
OBJECTIVE To analyze all published prospective, randomized, and blinded clinical studies on the proficiency-based progression (PBP) training using objective performance metrics. BACKGROUND The benefit of PBP methodology to learning clinical skills in comparison to conventional training is not settled. METHODS Search of PubMed, Cochrane library's Central, EMBASE, MEDLINE, and Scopus databases, from inception to 1st March 2020. Two independent reviewers extracted the data. The Medical Education Research Study Quality Instrument (MERSQI) was used to assess the methodological quality of included studies. Results were pooled using biased corrected standardized mean difference and ratio-of-means. Summary effects were evaluated using a series of fixed and random effects models. The primary outcome was the number of procedural errors performed comparing PBP and non-PBP-based training pathways. Secondary outcomes were the number of procedural steps completed and the time to complete the task/procedure. RESULTS From the initial pool of 468 studies, 12 randomized clinical studies with a total of 239 participants were included in the analysis. In comparison to the non-PBP training, ratio-of-means results showed that PBP training reduced the number of performance errors by 60% (P < 0.001) and procedural time by 15% (P = 0.003) and increased the number of steps performed by 47% (P < 0.001). CONCLUSIONS AND RELEVANCE Our systematic review and meta-analysis confirms that PBP training in comparison to conventional or quality assured training improved trainees' performances, by decreasing procedural errors and procedural time, while increasing the number of correct steps taken when compared to standard simulation-based training.

Abstract
BACKGROUND No data are available regarding the impact of time between a previous transrectal prostate biopsy (PB) and holmium laser enucleation of the prostate (HoLEP) on perioperative outcomes. OBJECTIVE To evaluate the impact of time from PB to HoLEP on perioperative outcomes. DESIGN, SETTING, AND PARTICIPANTS A total of 172 consecutive patients treated with HoLEP within 12 mo of a single previous transrectal PB at two tertiary centers were included. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Patients were stratified into two groups according to the median time from PB to HoLEP (namely, ≤6 and >6 mo). The primary outcome was intraoperative complications. Multivariate logistic regressions were used to identify the predictors of intraoperative complications. Linear regressions were used to test the association between the time from PB to HoLEP and intraoperative complications, enucleation efficiency, and enucleation time. RESULTS AND LIMITATIONS In total, 93 (54%) and 79 (46%) patients had PB ≤ 6 and >6 mo before HoLEP, respectively. Patients in PB ≤ 6 mo group experienced higher rates of intraoperative complications than those in PB > 6 mo group (14% vs 2.6%, p = 0.04). At multivariable analysis, time between PB and HoLEP was an independent predictor of intraoperative complications (odds ratio: 0.74; 95% confidence interval: 0.6-0.9; p = 0.006). Finally, the risk of intraoperative complications reduced by 1.5%, efficiency of enucleation increased by 4.1%, and enucleation time reduced by 1.7 min for each month passed from PB to HoLEP (all p ≤ 0.006). Selection of patients with only one previous PB represents the main limitation. CONCLUSIONS The time from PB to HoLEP of ≤6 mo is associated with a higher risk of intraoperative complications, lower enucleation efficacy, and longer enucleation time. PATIENT SUMMARY Patients with a prostate biopsy (PB) ≤6 mo before holmium laser enucleation of the prostate (HoLEP) had significantly worse outcomes than those with a PB > 6 mo before HoLEP.

Abstract
BACKGROUND Radiation therapy (RT) for prostate cancer (PCa) treatment is burdened by high rates of late urinary adverse events (UAEs). The feasibility of robot-assisted cystectomy (RAC) with intracorporeal urinary diversion (ICUD) for treatment of high-grade UAEs has never been assessed. OBJECTIVE To report perioperative outcomes, early (≤90 d) and late (>90 d) complications among patients undergoing RAC for UAEs after RT. DESIGN, SETTING, AND PARTICIPANTS We retrospectively evaluated 32 patients undergoing RAC with ICUD for UAEs in a single tertiary centre. SURGICAL PROCEDURE Surgery was performed using a da Vinci Xi system with adaptation for the primary treatment. MEASUREMENTS Perioperative outcomes included estimated blood loss (EBL), operative time (OT), intraoperative complications, and length of stay (LOS). Data for early and late postoperative complications were collected using the quality criteria recommended by the European Association of Urology. Univariate logistic regressions were performed to test the effect of baseline and perioperative characteristics on early postoperative complications. RESULTS AND LIMITATIONS The median age-adjusted Charlson comorbidity index (ACCI) was 6 (IQR 5-7). The indication for RAC was hemorrhagic radiation cystitis in 29 cases (91%), contracted bladder in two cases (6.2%), and urinary fistula in one case (3.1%). The median EBL, OT, and LOS were 250 ml, 330 min, and 10 d, respectively. A total of 31 (97%) patients received an ileal conduit. The 90-d rate of Clavien-Dindo grade ≥IIIa complications was 28%. The late complication rate was 46% and the perioperative mortality rate was 0%. On univariate analyses, ACCI was the only parameter correlated with the risk of early complications (odds ratio 1.75, 95% confidence interval 1.05-2.9; p = 0.03). The median follow-up was 30 mo (IQR 15-40). The lack of comparison with open cystectomy represents the main limitation. CONCLUSIONS RAC for UAEs in patients with a history of pelvic irradiation is a feasible option in high-volume centers. The use of new technologies can help to overcome some of the technical difficulties and reduce the risk of perioperative and late complications. PATIENT SUMMARY We report our experience with robot-assisted surgery for removal of the bladder in the management of urinary problems after radiation therapy for prostate cancer. When performed by highly experienced surgeons, this is a feasible procedure with outcomes and early and late complication rates that are acceptable.

Aetiology is poorly defined but dysfunctional inflammatory, autonomic and interoceptive (sensing of internal bodily signals) processes are implicated.ObjectivesTo investigate how altered interoception relates to baseline expression of pain, fatigue and anxiety symptoms in fibromyalgia and ME/CFS and in response to an inflammatory challenge.MethodsSixty-five patients with fibromyalgia and/or ME/CFS diagnosis and 26 matched controls underwent baseline assessment: pressure-pain thresholds and self-report questionnaires assessing pain, fatigue and anxiety severity. Participants received injections of typhoid (inflammatory challenge) or saline (placebo) in a randomised, double-blind, crossover design, before completing heartbeat tracking tasks. Three interoception dimensions were examined: subjective sensibility, objective accuracy and metacognitive awareness. Interoceptive trait prediction error was calculated as discrepancy between accuracy and sensibility.ResultsPatients with fibromyalgia and ME/CFS had significantly higher interoceptive sensibility and trait prediction error, despite no differences in interoceptive accuracy. Interoceptive sensibility and trait prediction error correlated with all self-report pain, fatigue and anxiety measures, and with lower pain thresholds. Anxiety mediated the positive-predictive relationships between pain (Visual Analogue Scale and Widespread Pain Index), fatigue impact and interoceptive sensibility. After inflammatory challenge, metacognitive awareness correlated with baseline self-reported symptom measures and lower pain thresholds.ConclusionsThis is the first study investigating interoceptive dimensions in patients with fibromyalgia and ME/CFS, which were found to be dysregulated and differentially influenced by inflammatory mechanisms. Interoceptive processes may represent a new potential target for diagnostic and therapeutic investigation in these poorly understood conditions.DisclosureNo significant relationships.

Selective Suturing or Sutureless Technique in Robot-assisted Partial Nephrectomy: Results from a Propensity-score Matched Analysis. Eur Urol Focus 2021; 8:506-513. [PMID: 33775611 DOI: 10.1016/j.euf.2021.03.019] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2021] [Revised: 02/26/2021] [Accepted: 03/14/2021] [Indexed: 01/25/2023]
Abstract
BACKGROUND Despite efforts aimed at preserving renal function, the functional decline after robot-assisted partial nephrectomy (RAPN) is not negligible. To address the risk of intraparenchymal vessel injuries during renorrhaphy, with consequent loss of functional renal parenchyma, we introduced a new surgical technique for RAPN. OBJECTIVE To compare perioperative patient outcomes between selective-suturing or sutureless RAPN (suRAPN) and standard RAPN (stRAPN). DESIGN, SETTING, AND PARTICIPANTS Ninety-two consecutive patients undergoing RAPN for a renal mass performed by a high-volume surgeon at a European tertiary center were included. Propensity-score matching was used to account for baseline differences between suRAPN and stRAPN patients. INTERVENTION RAPN using a selective-suturing or sutureless technique versus standard RAPN. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Perioperative outcomes included operative time, blood loss, length of stay, and intraoperative and 30-d postoperative complications. We also evaluated trifecta achievement (warm ischemia time ≤25 min, negative surgical margins, and no perioperative complications) and the incidence of postoperative acute kidney injury (AKI). We applied χ2 tests, t tests, and Kruskal-Wallis tests to assess differences in perioperative outcomes between suRAPN and stRAPN. RESULTS AND LIMITATIONS Overall, 29 patients (31%) were treated with suRAPN. Only one suRAPN patient experienced intraoperative complications (p = 0.9). Two suRAPN patients (6.9%) and four stRAPN patients (13.8%) experienced 30-d postoperative complications (p = 0.3). Operative time (110 vs 150 min; p < 0.01) and length of stay (2 vs 3 d; p = 0.02) were shorter for suRAPN than for stRAPN. The trifecta outcome was achieved in 25 suRAPN patients (86%) and 20 stRAPN patients (70%; p = 0.1). Only one suRAPN patient (3.4%) versus five stRAPN patients (17%) experienced postoperative AKI (p = 0.2). Finally, the decrease in the estimated glomerular filtration rate at 6-mo follow-up was lower in the suRAPN (-5.2%) than in the stRAPN group (-9.1%; p < 0.01). Lack of randomization represents the main study limitation. CONCLUSIONS A selective-suturing or sutureless technique in RAPN is feasible and safe. Moreover, suRAPN is a lower-impact surgical procedure. We obtained promising results for trifecta and functional outcomes, but prospective randomized trials are needed to validate the impact of selective suturing or a sutureless technique on long-term functional outcomes. PATIENT SUMMARY We assessed a new technique in robotic surgery to remove part of the kidney because of kidney cancer. Our new technique involves selective suturing or no suturing of the area from where the tumor is removed. We found that the rate of complications did not increase and the operating time and length of hospital stay were shorter using this new technique.

Abstract
Adenoid cystic carcinoma (ACC) is a rare malignant tumor, usually arising from salivary glands and rarely found in other locations. ACC is characterized by asymptomatic course, slow growth pattern, perineural invasion and high incidence of late metastasis. Renal localization of metastasis is rare. Only 12 cases of renal metastasis were published and, to our best knowledge, no case of bilateral metastasis to the kidney has ever been reported. We present a case of a 58 years old woman with bilateral renal metastasis from ACC of the right lung after fourteen years from lobectomy and radiotherapy for the primary presentation. The patient underwent bilateral robot-assisted partial nephrectomy in a two-stage approach. Despite its rare incidence and slow growth, ACC metastasis may simulate primary papillary renal carcinoma and occur many years after primary treatment. Therefore, lifelong follow-up, including abdominal imaging, is recommended.

Abstract
OBJECTIVE To evaluate the safety and efficacy of prostatic artery embolization in the management of LUTS secondary to BPH in elderly patients unfit for surgery. MATERIALS AND METHODS 17 elderly patients with moderate to severe LUTS/BPH were included in the study and treated with prostatic artery embolization. The patients were evaluated by transrectal ultrasonography (to assess prostate size), IPSS, and PVR urine volume preoperatively and 6 months after the procedure. RESULTS The mean age of patients was 76.67 ± 7.69. The mean prostate volume was 139.8 ± 81.83 g. The mean preoperative IPSS and PVR were 23 ± 5.4, and 94.43 ± 88.94 ml, respectively. The mean operative time was 90 minutes. Only three patients suffered from postoperative complications (two patients suffered from urinary tract infection and one patient had partial penile necrosis). At 6 months follow up, there was a significant reduction in the prostate volume (101 ± 73.65 cc), IPSS (12.5 ± 3.65), and PVR urine volume (48.64 ± 43.55). CONCLUSION prostatic artery embolization is a safe and effective nonsurgical alternative treatment of BPH/LUTS particularly in elderly patients with multiple comorbidities.

The Impact of Previous Prostate Surgery on Surgical Outcomes for Patients Treated with Robot-assisted Radical Cystectomy for Bladder Cancer. Eur Urol 2021; 80:358-365. [PMID: 33653634 DOI: 10.1016/j.eururo.2021.02.029] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2020] [Accepted: 02/12/2021] [Indexed: 12/01/2022]
Abstract
BACKGROUND The feasibility and safety of robot-assisted radical cystectomy (RARC) may be undermined by unfavorable preoperative surgical characteristics such as previous prostate surgery (PPS). OBJECTIVE To compare perioperative outcomes for patients undergoing RARC with versus without a history of PPS. DESIGN, SETTING, AND PARTICIPANTS The study included 220 consecutive patients treated with RARC and pelvic lymph node dissection for bladder cancer at a single European tertiary centre. Of these, 43 had previously undergone PPS, defined as transurethral resection of the prostate/holmium laser enucleation of the prostate (n=21) or robot-assisted radical prostatectomy (n=22). SURGICAL PROCEDURE RARC in patients with a history of PPS. MEASUREMENTS Data on postoperative complications were collected according to the quality criteria for accurate and comprehensive reporting of surgical outcomes recommended by the European Association of Urology guidelines. Multivariable logistic, linear, and Poisson regression analyses were performed to test the effect of PPS on surgical outcomes. RESULTS AND LIMITATIONS Overall, 43 patients (20%) were treated with RARC after PPS. Operative time (OT) was longer in the PPS group (360 vs 330min; p<0.001). Patients with PPS experienced higher rates of intraoperative complications (19% vs 6.8%) and higher rates of 30-d (67% vs 39%), and Clavien-Dindo >3 (33% vs 16%) postoperative complications (all p<0.05). Moreover, the positive surgical margin (PSM) rate after RARC was higher in the PPS group (14% vs 4%; p=0.03). On multivariable analyses, PPS at RARC independently predicted higher risk of intraoperative (odds ratio [OR] 2.10, 95% confidence interval [CI] 1.04-6.21; p=0.01) and 30-d complications (OR 2.26, 95% CI 1.05-5.22; p=0.02), as well as longer OT (relative risk [RR] 1.03, 95% CI 1.00-1.05; p=0.02) and length of stay (RR 1.13, 95% CI 1.02-1.26; p=0.02). Lack of randomization represents the main limitation. CONCLUSIONS RARC in patients with a history of PPS is feasible, but it is associated with a higher risk of complications and longer OT and length of stay. Moreover, higher PSM rates have been reported for these patients. Thus, measures aimed at improving surgical outcomes appear to be warranted. PATIENT SUMMARY We investigated the effect of previous prostate surgery (PPS) on surgical outcomes after robot-assisted removal of the bladder. We found that patients with PPS have a higher risk of complications and longer hospitalization after bladder removal. These patients deserve closer evaluation before this type of bladder operation.

Abstract
Introduction: The Coronavirus disease-2019 (COVID-19) has been declared as a pandemic in March 2020 by the World Health Organization (WHO). Since then, this pandemic has dramatically affected the entire world, even radically influencing the way patients are framed at triage. Symptoms and tests in most cases lead to a correct diagnosis; however, error may be around the corner. Case report: A 60 years old patient was referred with weight loss, fatigue and mild fever for 3 weeks as he was working in a COVID-19 ward. After a positive swab and chest CT scan, he was admitted in the hospital and treated as mild COVID-19 patient. A CT scan performed after the patient was discharged revealed a renal lesion misidentified as a tumor then clarified to be an abscess which retrospectively appears to be the main cause of his symptoms. Conclusion: Clinicians should consider other life-threatening disease in the differential diagnosis of patients presenting with similar symptoms to minimize mistakes and avoid further unnecessary investigations.
