Malar augmentation with zygomatic osteotomy in orthognatic surgery: Bone and soft tissue changes threedimensional evaluation: Malar Augmentation in Orthognatic Surgery

Background: The aim of this prospective study is to objectively assess 3D soft tissue and bone changes of the malar region by using the malar valgization osteotomy in concomitant association with orthognatic surgery. Materials and methods: From January 2015 to January 2018, 10 patients who underwent single stage bilateral malar valgization osteotomy in conjunction with maxillo-mandibular orthognatic procedures for aesthetic and functional correction were evaluated. Clinical and surgical reports were collected and patient satisfaction was evaluated with a VAS score. For each patient, maxillofacial CT-scans were collected 1 month preoperatively (T0) and 6 months after the operation (T1). DICOM data were imported and elaborated in the software MatLab, which creates a 3D soft tissue model of the face. 3D Bone changes were assessed importing DICOM data into iPlan (BrainLAB 3.0) software and the superimposition process was achieved using autofusion. Descriptive statistical analyses were obtained for soft tissue and bone changes. Results: Considering bone assessment the comparison by superimposition between T0 and T1 showed an increase of the distance between bilateral malar prominence (Pr – Pl) and a slight forward movement (87,65 ± 1,55 to 97,60 ± 5,91); p-value 0.007. All of the patients had improvement of α angle, ranging from 36,30 ± 1,70 to 38,45 ± 0,55, p-value 0,04 (αr) and 36,75 ± 1,58 to 38,45 ± 0,35; p-value 0,04 (αl). The distance S increased from 78,05 ± 2,48 to 84,2 ± 1,20; p-value 0,04 (Sr) and 78,65 ± 2,16 to 82,60 ± 0,90 (Sl); p-value 0,03. Considering the soft tissue, the comparison by superimposition between T0 and T1 showed an antero-lateral movement (p-value 0.008 NVL; p-value 0.001 NVR) of the malar bone projection together with an increase in width measurements (p-value 0,05 VL; p-value 0,01 VR). Angular measurement confirmed the pattern of the bony changes (p-value 0.034 αL; p-value 0,05 αR). Conclusion: The malar valgization osteotomy in conjunction with orthognatic surgery is effective in improving zygomatic projection contributing to a balanced facial correction in midface hypoplasia.3D geometrical based volume and surface analysis demonstrate an increase in transversal and forward direction. The osteotomy can be safely performed in conjunction with orthognatic procedures

Segmental Ureterectomy for Upper Tract Urothelial Carcinoma: A Systematic Review and Meta-analysis of Comparative Studies

Radical nephroureterectomy (RNU) represents the standard of care for high-risk upper tract urothelial carcinoma (UTUC). In selected patients with ureteral UTUC, a conservative approach such as segmental ureterectomy (SU) can be considered. However, this therapeutic option remains controversial. The aim of this study was to perform a systematic review and meta-analysis of studies assessing the outcomes of SU versus RNU in patients with UTUC. Three search engines (Scopus, Embase, and Web of Science) were queried up to May 2019. The Preferred Reporting Items for Systematic Review and Meta-analysis Statement (PRISMA Statement) was used as a guideline for study selection. The clinical question was established as stated in the PICO (Population, Intervention, Comparator, Outcome) process. Patients in the SU group were more likely to have history of bladder cancer (odds ratio [OR], 1.99; 95% confidence interval [CI], 1.12-3.51; P = .02), but less likely to present with preoperative hydronephrosis (OR, 0.52; 95% CI: 0.31-0.88; P = .02). A higher rate of ureteral tumor location was found in the SU group (OR, 7.54; 95% CI, 4.15-13.68; P < .00001). The SU group presented with a lower rate of higher (pT ≥ 2) stage (OR, 0.66; 95% CI, 0.53-0.82; P = .0002), and high-grade tumors (OR, 0.62; 95% CI, 0.50-0.78; P < .0001). The SU group was found to have shorter 5-year relapse-free survival (OR, 0.64; 95% CI, 0.43-0.95; P = .03), but higher postoperative estimated glomular filtration rate (weighted mean difference, 10.97 mL/min; 95% CI, 2.97-18.98; P = .007). Selected patients might benefit from SU as a therapeutic option for UTUC. In advanced high-risk disease, RNU still remains the standard of care

Prostate cancer biomarkers: a practical review based on different clinical scenarios

Traditionally, diagnosis and staging of prostate cancer (PCa) have been based on prostate-specific antigen (PSA) level, digital rectal examination (DRE), and transrectal ultrasound (TRUS) guided prostate biopsy. Biomarkers have been introduced into clinical practice to reduce the overdiagnosis and overtreatment of low-grade PCa and increase the success of personalized therapies for high-grade and high-stage PCa. The purpose of this review was to describe available PCa biomarkers and examine their use in clinical practice. A nonsystematic literature review was performed using PubMed and Scopus to retrieve papers related to PCa biomarkers. In addition, we manually searched websites of major urological associations for PCa guidelines to evaluate available evidence and recommendations on the role of biomarkers and their potential contribution to PCa decision-making. In addition to PSA and its derivates, thirteen blood, urine, and tissue biomarkers are mentioned in various PCa guidelines. Retrospective studies have shown their utility in three main clinical scenarios: (1) deciding whether to perform a biopsy, (2) distinguishing patients who require active treatment from those who can benefit from active surveillance, and (3) defining a subset of high-risk PCa patients who can benefit from additional therapies after RP. Several validated PCa biomarkers have become commercially available in recent years. Guidelines now recommend offering these tests in situations in which the assay result, when considered in combination with routine clinical factors, is likely to affect management. However, the lack of direct comparisons and the unproven benefits, in terms of long-term survival and cost-effectiveness, prevent these biomarkers from being integrated into routine clinical use

Head to Head Impact of Margin, Ischemia, Complications, Score Versus a Novel Trifecta Score on Oncologic and Functional Outcomes After Robotic-assisted Partial Nephrectomy: Results of a Multicenter Series

BACKGROUND: There is a paucity of data describing the ability of margin, ischemia, complications, score (MIC) and trifecta in predicting long-term outcomes of robotic-assisted partial nephrectomy (RAPN).OBJECTIVE: To compare a novel trifecta (negative margins, no significant complications, and perioperative estimated glomerular filtration rate [eGFR] decrease 6430%) versus standard MIC as predictors of oncologic and functional results in a large series of RAPNs.DESIGN, SETTING, AND PARTICIPANTS: Between 2009 and 2019, a multicenter dataset was queried for patients with nonmetastatic renal masses who underwent RAPN at eight participating institutions.INTERVENTION: RAPN.OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: MIC and trifecta achievement were determined for the overall cohort and a subgroup undergoing off-clamp RAPN (ocRAPN), respectively. The overall survival (OS), recurrence-free survival (RFS), and new onset of end-stage renal disease (ESRD; defined as eGFR &lt;30 ml/min) probabilities were assessed by the Kaplan-Meier method. Cox regression analyses were used to identify predictors of OS, RFS, and ESRD. For all analyses, two-sided p &lt; 0.05 was considered significant.RESULTS AND LIMITATIONS: Out of 1807 patients, MIC and trifecta were achieved in 71.1% (n = 1285) and 82.6% (n = 1492), respectively, and once restricted to the ocRAPN cohort, in 95.6% (n = 625) and 81.6% (n = 534), respectively. On Kaplan-Meier analysis, both MIC and trifecta achievement predicted higher OS and lower ESRD probabilities (all p &lt; 0.014), while only trifecta achievement was a predictor of RFS probabilities (p = 0.009). On multivariable Cox regression, MIC did not predict any of the endpoints independently, while trifecta achievement was an independent predictor of higher OS (hazard ratio [HR] 0.4, 95% confidence interval [CI] 0.18-0.86; p = 0.019) and lower ESRD development probabilities (HR 0.32, 95% CI 0.15-0.72; p = 0.005).CONCLUSIONS: Trifecta, initially described as comprehensive measures of perioperative outcomes, needs to stand the test of time. Compared with MIC, the recent trifecta was an independent predictor of clinically significant endpoints, namely, survival and ESRD development probabilities.PATIENT SUMMARY: Our novel trifecta represents a reliable method for estimating survival and development of end-stage renal disease after robotic-assisted partial nephrectomy

Outcomes and predictors of benign histology in patients undergoing robotic partial or radical nephrectomy for renal masses: A multicenter study

Introduction Theaim of this study was to assess preoperative factors associated with benign histology in patients undergoing surgical removal of a renal mass and to analyze outcomes of robotic partial nephrectomy (PN) and radical nephrectomy (RN) for these masses. Material and methods Overall, 2,944 cases (543 benign and 2,401 malignant) who underwent robotic PN and RN between 2003–2018 at 10 institutions worldwide were included. The assessment of the predictors of benign histology was made at the final surgical pathology report. Descriptive statistics, Mann-Whitney U, Pearson’s χ2, and logistic regression analysis were used. Results Patients in the benign group were mostly female (61 vs. 33%; p <0.001), with lower body mass index (BMI) (26.0 vs. 27.1 kg/m2; p <0.001). The benign group presented smaller tumor size (2.8 vs. 3.5 cm; p <0.001), R.E.N.A.L. score (6.0 vs. 7.0; p <0.001). There was a lower rate of hilar (11 vs.18%; p = 0.001), cT≥3 (1 vs. 4.5%; p <0.001) tumors in the benign group. There was a statistically significant higher rate of PN in the benign group (97 vs. 86%; p <0.001) as well as a statistically significant lower 30-day re-admission rate (2 vs. 5%; p = 0.081). Multivariable analysis showed male gender (OR: 0.52; p <0.001), BMI (OR: 0.95; p <0.001), and cT3a (OR: 0.22; p = 0.005) to be inversely associated to benign histology. Conclusions In 18% of cases, a benign histologic type was found. Only 3% of these tumors were treated with RN. Female gender, lower BMI, and higher T staging showed to be independent predictors of benign histology

New Ultra-minimally Invasive Surgical Treatment for Benign Prostatic Hyperplasia: A Systematic Review and Analysis of Comparative Outcomes

Context: Benign prostatic hyperplasia (BPH) associated with lower urinary tract symptoms (LUTS) is diagnosed in up to 80% of men during their lifetime. Several novel ultra-minimally invasive surgical treatments (uMISTs) for BPH/benign prostatic obstruction (BPO) have become available over the past 5 yr. Objective: To evaluate the perioperative and functional outcomes of recently introduced uMISTs for BPH/BPO, including Urolift, Rezūm, temporary implantable nitinol device, prostatic artery embolization (PAE), and intraprostatic injection. Evidence acquisition: A systematic literature search was conducted in December 2020 using Medline (via PubMed), Embase (via Ovid), Scopus, and Web of Science (registered on PROSPERO as CRD42021225014). The search strategy used PICO criteria and article selection was conducted in accordance with the PRISMA guidelines. The risk of bias and the quality of the articles included were assessed. A dedicated data extraction form was used to collect the data of interest. Pooled and cumulative analyses were performed to compare perioperative and functional outcomes between study groups. A random-effects model using the DerSimonian and Laird method was used to evaluate heterogeneity. Stata version 15.0 software was used for all statistical analyses. Evidence synthesis: The initial electronic search identified 3978 papers, of which 48 ultimately met the inclusion criteria and were included in the analysis. Pooled analysis revealed a uMIST benefit in terms of International Prostate Symptom Score (IPSS; −9.81 points, 95% confidence interval [CI] −11.37 to −8.25 at 1 mo; −13.13 points, 95% CI −14.98 to −11.64 at 12 mo), maximum flow rate (from +3.66 ml/s, 95% CI 2.8–4.5 to +4.14 ml/s, 95% CI 0.72–7.56 at 12 mo), and postvoid residual volume (−10.10 ml, 95% CI −27.90 to 7.71 at 12 mo). No negative impact was observed on scores for the International Index of Erectile Function-5, Male Sexual Health Questionnaire-Ejaculatory Dysfunction bother and function scales (overall postintervention change in pooled median score of 1.88, 95% CI 1.34–2.42 at the start of follow-up; and 1.04, 95% CI 0.28–1.8 after 1 yr), or the IPSS-Quality of Life questionnaire. Conclusions: Novel uMISTs can yield fast and effective relief of LUTS without affecting patient quality of life. Only Rezūm, UroLift, and PAE had a minimal impact on patients’ sexual function with respect to baseline, especially regarding preservation of ejaculation. Patient summary: We reviewed outcomes for recently introduced ultra-minimally invasive surgical treatments for patients with lower urinary tract symptoms caused by benign prostate enlargement or obstruction. The evidence suggests that these novel techniques are beneficial in terms of controlling symptoms while preserving sexual function. Take Home Message: Novel ultra-minimally invasive treatments can yield fast and effective relief of lower urinary tract symptoms without affecting a patient's quality of life

Outcomes of minimally invasive partial nephrectomy among very elderly patients: Report from the resurge collaborative international database

The aim of the study was to perform a comprehensive investigation of clinical outcomes of robot-assisted partial nephrectomy (RAPN) or laparoscopic partial nephrectomy (LPN) in elderly patients presenting with a renal mass.The REnal SURGery in Elderly (RESURGE) collaborative database was queried to identify patients aged 75 or older diagnosed with cT1-2 renal mass and treated with RAPN or LPN. Study outcomes were: overall complications (OC); warm ischemia time (WIT) and 6-month estimated glomerular filtration rate (eGFR); positive surgical margins (PSM), disease recurrence (REC), cancer-specific mortality (CSM) and other-cause mortality (OCM). Descriptive statistics, Kaplan-Meier, smoothed Poisson plots and logistic and linear regression models (MVA) were used.Overall, 216 patients were included in this analysis. OC rate was 34%, most of them being of low Clavien grade. Median WIT was 17 minutes and median 6-month eGFR was 54 ml/min/1.73 m(2). PSM rate was 5%. After a median follow-up of 20 months, the 5-year rates of REC, CSM and OCM were 4, 4 and 5%, respectively. At MVA predicting perioperative morbidity, RAPN relative to LPN (odds ratio [OR] 0.33; p &lt;0.0001) was associated with lower OC rate. At MVA predicting functional outcomes, RAPN relative to LPN was associated with shorter WIT (estimate [EST]-4.09; p &lt;0.0001), and with higher 6-month eGFR (EST 6.03; p = 0.01).In appropriately selected patients with small renal masses, minimally-invasive PN is associated with acceptable perioperative outcomes. The use of a robotic approach over a standard laparoscopic approach can be advantageous with respect to clinically relevant outcomes, and it should be preferred when available
