RESUMEN
Objective: To correlate the utility of the Fundamentals of Laparoscopic Surgery (FLS) manual skills program with the Objective Structured Assessment of Technical Skills (OSATS) global rating scale in evaluating operative performance. Methods: The Asian Urological Surgery Training and Educational Group (AUSTEG) Laparoscopic Upper Tract Surgery Course implemented and validated the FLS program for its usage in laparoscopic surgical training. Delegates' basic laparoscopic skills were assessed using three different training models (peg transfer, precision cutting, and intra-corporeal suturing). They also performed live porcine laparoscopic surgery at the same workshop. Live surgery skills were assessed by blinded faculty using the OSATS rating scale. Results: From March 2016 to March 2019, a total of 81 certified urologists participated in the course, with a median of 5 years of post-residency experience. Although differences in task time did not reach statistical significance, those with more surgical experience were visibly faster at completing the peg transfer and intra-corporeal suturing FLS tasks. However, they took longer to complete the precision cutting task than participants with less experience. Overall OSATS scores correlated weakly with all three FLS tasks (peg transfer time: r=-0.331, r 2=0.110; precision cutting time: r=-0.240, r 2=0.058; suturing with intra-corporeal knot time: r=-0.451, r 2=0.203). Conclusion: FLS task parameters did not correlate strongly with OSATS globing rating scale performance. Although FLS task models demonstrated strong validity, it is important to assimilate the inconsistencies when benchmarking technical proficiency against real-life operative competence, as evaluated by FLS and OSATS, respectively.
RESUMEN
BACKGROUND: The duplex kidney is one of the common congenital anomalies of the kidney and urinary tract. We present two cases of renal tumor accompanied with ipsilateral duplex kidney. The image of the tumor, renal artery system and collecting system were rendered by AI software (Fujifilm's Synapse® AI Platform) to support the diagnosis and surgical planning. CASE PRESENTATION: Two Vietnamese patients (a 45-year-old man and a 54-year-old woman) with incidental cT1 renal cell carcinoma (RCC) were confirmed to have ipsilateral duplex kidneys by 3D reconstruction AI technique. One patient had a Renal score 9ah tumor of left kidney while the other had a Renal score 9 × tumor of right kidney in which a preoperative CT scan failed to identify a diagnosis of duplex kidney. Using the Da Vinci platform, we successfully performed robotic partial nephrectomy without any damage to the collecting system in both cases. CONCLUSION: RCC with duplex kidneys is a rare condition. By utilizing a novel AI reconstruction technique with adequate information, two patients with RCC in duplex kidneys were successfully performed robotic partial nephrectomy without complication.

Background: Emphysematous pyelonephritis (EPN) is a necrotizing infection of the kidney and the surrounding tissues associated with considerable mortality. We aimed to formulate a score that classifies the risk of mortality in patients with EPN at hospital admission. Materials and methods: Patients diagnosed with EPN between 2013 and 2020 were retrospectively included. Data from 15 centers (70%) were used to develop the scoring system, and data from 7 centers (30%) were used to validate it. Univariable and multivariable logistic regression analyses were performed to identify independent factors related to mortality. Receiver operating characteristic curve analysis was performed to construct the scoring system and calculate the risk of mortality. A standardized regression coefficient was used to quantify the discriminating power of each factor to convert the individual coefficients into points. The area under the curve was used to quantify the scoring system performance. An 8-point scoring system for the mortality risk was created (range, 0-7). Results: In total, 570 patients were included (400 in the test group and 170 in the validation group). Independent predictors of mortality in the multivariable logistic regression were included in the scoring system: quick Sepsis-related Organ Failure Assessment score ≥2 (2 points), anemia, paranephric gas extension, leukocyte count >22,000/µL, thrombocytopenia, and hyperglycemia (1 point each). The mortality rate was <5% for scores ≤3, 83.3% for scores 6, and 100% for scores 7. The area under the curve was 0.90 (95% confidence interval, 0.84-0.95) for test and 0.91 (95% confidence interval, 0.84-0.97) for the validation group. Conclusions: Our score predicts the risk of mortality in patients with EPN at presentation and may help clinicians identify patients at a higher risk of death.
RESUMEN
Deceased donor kidney transplantation (DDKT) is common in high income Western countries with high transplantation rates. However, the utilization of deceased organs is suboptimal in Asia, due to a multitude of factors. Coherent policies are integral to the development of DDKT programs and deterrence of commercialization, but most are still at an infancy and formative stage in Asia. This review article identifies the glass ceiling effects of social, cultural, religious, political, and technical factors hampering the progress of DDKT in Asia. Additionally, it reviews the history of policy development in different countries and describes their idiosyncratic barriers and challenges. Lastly, it discusses innovative policy measures that can be undertaken to proliferate DDKT practice and curtail commercialization. The long-term ideal is to achieve regional equity and self-sufficiency, through a shared ethos of social and ethical responsibility that transcends and resonates with the different segments of the Asian community.
RESUMEN
Objective: To scrutinize the definitions of minimal invasive surgical therapy (MIST) and to investigate urologists' knowledge, attitudes, and practices for benign prostatic obstruction surgeries. Methods: A 36-item survey was developed with a Delphi method. Questions on definitions of MIST and attitudes and practices of benign prostatic obstruction surgeries were included. Urologists were invited globally to complete the online survey. Consensus was achieved when more than or equal to 70% responses were "agree or strongly agree" and less than or equal to 15% responses were "disagree or strongly disagree" (consensus agree), or when more than or equal to 70% responses were "disagree or strongly disagree" and less than or equal to 15% responses were "agree or strongly agree" (consensus disagree). Results: The top three qualities for defining MIST were minimal blood loss (n=466, 80.3%), fast post-operative recovery (n=431, 74.3%), and short hospital stay (n=425, 73.3%). The top three surgeries that were regarded as MIST were Urolift® (n=361, 62.2%), Rezum® (n=351, 60.5%), and endoscopic enucleation of the prostate (EEP) (n=332, 57.2%). Consensus in the knowledge section was achieved for the superiority of Urolift®, Rezum®, and iTIND® over transurethral resection of the prostate with regard to blood loss, recovery, day surgery feasibility, and post-operative continence. Consensus in the attitudes section was achieved for the superiority of Urolift®, Rezum®, and iTIND® over transurethral resection of the prostate with regard to blood loss, recovery, and day surgery feasibility. Consensus on both sections was achieved for EEP as the option with the better symptoms and flow improvement, lower retreatment rate, and better suitable for prostate more than 80 mL. Conclusion: Minimal blood loss, fast post-operative recovery, and short hospital stay were the most important qualities for defining MIST. Urolift®, Rezum®, and EEP were regarded as MIST by most urologists.
RESUMEN
BACKGROUND: Accurate prediction of post-donor nephrectomy (DN) glomerular filtration rate is potentially useful for evaluating and counselling living kidney donors. Currently, there are limited tools to evaluate post-operative new-baseline glomerular filtration rate (NBGFR) in kidney donors. We aim to validate a conceptually simple formula based on split renal function (SRF) previously developed for radical nephrectomy patients. METHODS: Eighty-three consecutive patients who underwent DN from 2010 to 2016 were included. Pre-operative CT imaging and functional data including pre-DN baseline Global GFR (108.2 ± 13.2 mL/min/1.73m2) were included. Observed NBGFR was defined as the latest eGFR 3-12 months post-DN. SRF, defined as volume of the contralateral non-resected kidney normalised by total volume of kidneys, was determined from pre-operative cross-sectional imaging (49.2 ± 2.36%). The equation derived from Rathi et al. is as detailed: Predicted NBGFR = 1.24 × (Global GFR Pre-DN) x (SRF). RESULTS: The relationship between predicted NBGFR (66.0 ± 8.29 mL/min/1.73m2) and observed NBGFR (74.9 ± 16.4 mL/min/1.73m2) was assessed by evaluating correlation coefficients, bias, precision, accuracy, and concordance. The new SRF-based formula for NBGFR prediction correlated strongly with observed post-operative NBGFR (Pearson's r = 0.729) demonstrating minimal bias (median difference = 7.190 mL/min/1.73m2) with good accuracy (96.4% within ± 30%, 62.7% within ± 15%) and precision (IQR of bias = - 0.094 to 16.227). CONCLUSION: The SRF-based formula was also able to accurately discriminate all but one patient to an NBGFR of > 45 mL/min/1.73m2. We utilised the newly developed SRF-based formula for predicting NBGFR in a living kidney donor population. Counselling of donor post-operative renal outcomes may then be optimised pre-operatively.

INTRODUCTION: Androgen receptor targeted agents (ARTA) have increasingly been incorporated into treatment regimens for various stages of prostate cancer. Patients are living longer with prostate cancer, and thus have a higher cumulative exposure to the treatment and its accompanying side effects, especially those of cardiovascular disease. We aim to assess the differences in the incidence of cardiac-related adverse events after treatment of prostate cancer with ARTA versus placebo. METHODS: Three databases were thoroughly searched for relevant articles. The PICOS model was used to frame our clinical question, with which 2 independent authors went through several rounds of screening to select the final included studies. Meta-analysis was done using the Cochran-Mantel-Haenszel Method. Quality assessment was carried out with the Cochrane Risk of Bias tool RoB 2. RESULTS: The use of ARTA in prostate cancer increases the incidence of cardiac-related adverse events (RR: 1.56, 95% CI: 1.29-1.90, p < 0.00001), such as hypertension (RR: 1.69, 95% CI: 1.46-1.97, p < 0.00001), ischaemic heart disease (RR: 1.84, 95% CI: 1.36-2.50, p < 0.0001), and arrhythmia (RR: 1.38, 95% CI: 1.11-1.71, p = 0.004), although this did not manifest in an increased incidence of cardiac arrests/deaths (RR: 1.28, 95% CI: 0.87-1.88, p = 0.21). DISCUSSION: ARTA increases the risk of cardiac-related adverse events, hypertension, ischaemic heart disease and arrhythmia. Armed with this knowledge, we will be better poised to manage cardiac risks accordingly and involve a cardiologist as required when starting patients on ARTA.

We aim to evaluate the incidence of incontinence following laser endoscopic enucleation of the prostate (EEP) comparing en-bloc (Group 1) versus 2-lobe/3-lobe techniques (Group 2). We performed a retrospective review of patients undergoing EEP for benign prostatic enlargement in 12 centers between January 2020 and January 2022. Data were presented as median and interquartile range (IQR). Univariable and multivariable logistic regression analysis was performed to evaluate factors associated with stress urinary incontinence (SUI) and mixed urinary incontinence (MUI). There were 1711 patients in Group 1 and 3357 patients in Group 2. Patients in Group 2 were significantly younger (68 [62-73] years vs 69 [63-74] years, P = 0.002). Median (interquartile range) prostate volume (PV) was similar between the groups (70 [52-92] ml in Group 1 vs 70 [54-90] ml in Group 2, P = 0.774). There was no difference in preoperative International Prostate Symptom Score, quality of life, or maximum flow rate. Enucleation, morcellation, and total surgical time were significantly shorter in Group 1. Within 1 month, overall incontinence rate was 6.3% in Group 1 versus 5.3% in Group 2 ( P = 0.12), and urge incontinence was significantly higher in Group 1 (55.1% vs 37.3% in Group 2, P < 0.001). After 3 months, the overall rate of incontinence was 1.7% in Group 1 versus 2.3% in Group 2 ( P = 0.06), and SUI was significantly higher in Group 2 (55.6% vs 24.1% in Group 1, P = 0.002). At multivariable analysis, PV and IPSS were factors significantly associated with higher odds of transient SUI/MUI. PV, surgical time, and no early apical release technique were factors associated with higher odds of persistent SUI/MUI.

Radiomics is increasingly applied to the diagnosis, management, and outcome prediction of various urological conditions. The purpose of this scoping review is to evaluate the current evidence of the application of radiomics in kidney transplantation, especially its utility in diagnostics and therapeutics. An electronic literature search on radiomics in the setting of transplantation was conducted on PubMed, EMBASE, and Scopus from inception to September 23, 2022. A total of 16 studies were included. The most widely studied clinical utility of radiomics in kidney transplantation is its use as an adjunct to diagnose rejection, potentially reducing the need for unnecessary biopsies or guiding decisions for earlier biopsies to optimize graft survival. Technology such as optical coherence tomography is a noninvasive procedure to build high-resolution optical cross-section images of the kidney cortex in situ and in real time, which can provide histopathological information of donor kidney candidates for transplantation, and to predict posttransplant function. This review shows that, although radiomics in kidney transplants is still in its infancy, it has the potential for large-scale implementation. Its greatest potential lies in the correlation with conventional established diagnostic evaluation for living donors and potential in predicting and detecting rejection postoperatively.

BACKGROUND: Selecting the smaller kidney for donation has been advocated if there is a size difference of > 10% between the 2 kidneys but has never been prospectively evaluated. With increase in donor nephrectomies, it is important to evaluate this to minimize loss of renal function to donors. METHODS: 75 consecutive donor nephrectomy patients were included in our longitudinal study. The Split Renal Volume (SRV) of bilateral kidneys were measured using contrasted computer tomography scans and patients segregated into 2 groups depending on donated kidney having more (Group 1) or less than (Group 2) 52.5% of SRV. RESULTS: Patients in Group 1 (n = 19) and 2 (n = 56) were of similar age (43.8 vs. 48.3), BMI (22.4 vs. 25.2), sex (57.9 vs. 55.4% women), respectively. Although total kidney volumes were similar in both groups, Group 1 had significantly smaller right kidney volumes (120.4 ± 24.9 vs. 142.7 ± 28.4 mls, p = 0.003). EGFR pre-operatively (116.3 ± 20.8 vs. 106.3 ± 23.8 mL/min/1.73 m2) and at 6-months (65.7 ± 13.3 vs. 66.9 ± 15.5 mL/min/1.73 m2) were not different between groups. However, patients in Group 1 had significantly greater absolute (50.6 ± 14.9 vs. 39.5 ± 14.7 mL/min/1.73 m2) and relative decline (43.0 ± 8.6 vs. 36.3 ± 10.6%) in eGFR at 6 months (p = 0.06, 0.009). CONCLUSION: With a SRV difference of 5% between the 2 sides, removal of the larger kidney for living kidney donation resulted in greater early decline of renal function than kidney donors whose larger or equivalent kidney is preserved.

BACKGROUND: We aimed to analyze the influence of near-infrared fluorescence (NIRF) using indocyanine green (ICG) with standard robot-assisted partial nephrectomy (RAPN) in patients with a kidney tumor (KT). METHODS: We performed a literature search on 12 September 2023 through PubMed, EMBASE, and Scopus. The analysis included observational studies that examined the perioperative and long-term outcomes of patients with a KT who underwent RAPN with NIRF. RESULTS: Overall, eight prospective studies, involving 535 patients, were eligible for this meta-analysis, with 212 participants in the ICG group and 323 in the No ICG group. For warm ischemia time, the ICG group showed a lower duration (weighted Mean difference (WMD) = -2.05, 95% confidence interval (CI) = -3.30--0.80, p = 0.011). The postoperative eGFR also favored the ICG group (WMD = 7.67, 95% CI = 2.88-12.46, p = 0.002). No difference emerged for the other perioperative outcomes between the two groups. In terms of oncological radicality, the positive surgical margins and tumor recurrence rates were similar among the two groups. CONCLUSIONS: Our meta-analysis showed that NIRF with ICG during RAPN yields a favorable impact on functional outcomes, whereas it exerts no such influence on oncological aspects. Therefore, NIRF should be adopted when preserving nephron function is a paramount concern.
RESUMEN
INTRODUCTION: In this case report, we demonstrate our technique of a retroperitoneal laparoscopic heminephrectomy for a T1b right hilar tumor in a horseshoe kidney. CASE PRESENTATION: A 77-year-old Vietnamese woman presented to the hospital because of right flank pain. On presentation, her serum creatinine was 0.86 mg/dL and glomerular filtration rate was 65.2 mL/minute/1.73 m2. According to her renal scintigraphy, glomerular filtration rates of the right and left moieties were 24.2 and 35.5 mL/minute, respectively. Computed tomography imaging demonstrated a 5.5 × 5.0 cm solid hilar mass with a cT1bN0M0 tumor stage was in the right moiety. After discussion, the patient elected a minimally invasive surgery to treat her malignancy. The patient was placed in a flank position. We used Gaur's balloon technique to create the retroperitoneal working space, and four trocar ports were planned for operation. Three arteries were dissected, including two arteries feeding the right moiety, one artery feeding the isthmus, and one vein, which was clipped and divided by Hem-o-lok. The isthmusectomy was performed with an Endostapler. Consequently, the ureter was clipped and divided. Finally, the whole right segment of the horseshoe kidney was mobilized and taken out via the flank incision. RESULTS: The total operative time was 250 min with an estimated blood loss of 200 mL. The patient's serum creatinine after surgery was 1.08 mg/dL, and glomerular filtration rate was 49.47 mL/minute/1.73 m2. The patient was discharged on postoperative day #4 without complication. Final pathologic examination of the tumor specimen revealed a Fuhrman grade II clear cell renal cell carcinoma, capsular invasion, with negative surgical margins. After a three-month follow-up, the serum creatinine was 0.95 mg/dL, and glomerular filtration rate was 57.7 mL/minute/1.73 m2. Local recurrence or metastasis was not detected by follow-up computed tomography imaging. CONCLUSIONS: Retroperitoneal laparoscopic heminephrectomy is a safe and feasible technique for patients with renal cell carcinoma in a horseshoe kidney and may be particularly useful in low income settings without access to robotic technology.

Introduction: Epidemiological outcomes of renal cell carcinoma (RCC) remain sparse. This study aims to compare preoperative characteristics, surgical outcomes, and oncological outcomes of RCC patients at a urology unit in Singapore.Methods: A retrospective cohort analysis of 137 RCC patients in the National University Hospital of Singapore who had undergone partial nephrectomy between 2009 and 2020 was conducted. χ2 tests (Chi-Square Test, Fisher's Exact Test) and one-way analysis of variance (ANOVA) were used for comparing categorical and continuous variables respectively. Kaplan-Meier estimates were used for survival analysis.Results: In total, 137 patients were identified (Chinese [n=82], Malay [n=19], Indian [n=15], Others [n=21]). Indian patients were diagnosed at an earlier age (52.13±10.52 years, P=0.018). A larger percentage of Malay patients (78.9%, P<0.001) were operated on before 2016, prior to the center's adoption of the robotic surgical technique. More Malay and Indian patients underwent laparoscopic surgery (36.8% and 46.7%, P=0.008), experiencing higher rates of intra-operative conversions compared to the Chinese and other ethnicities (5.3% and 13.3% vs. 0%, P=0.011). They also had longer post-operative stays compared to Chinese (7.42±6.46 days; 7.40±7.69 days vs. 4.88±2.87 days, P=0.036). Malays were much less likely to undergo robotic partial nephrectomy compared to Chinese patients (OR=0.295, 95% CI=0.102-0.856) and had the highest rate of metastatic recurrence (10.5%, P=0.023).

BACKGROUND: With an increasing reliance on online sources for medical information, we studied the quality and completeness of health literacy videos on TikTok regarding BPH. METHODS: A cross-sectional systematic evaluation of TikTok videos using the search term "Benign Prostatic Hyperplasia" was performed on 14th April 2023, and included 49 patient information and educational videos. The videos were then analysed by two reviewers and scored using two instruments: the DISCERN instrument and a completeness analysis. RESULTS: Of the 49 videos, 38 were created by healthcare professionals (HCPs). The average length of each video was 62.7 ± 59.3 s, with a large average number of total views (24,990.1 ± 109,534.9 views). The DISCERN score trended higher in every category in videos published by HCPs compared to non-HCPs, with HCPs providing a statistically significant increase in reliability (19.0,14.6, p < 0.05) and total score (29.4,23, p < 0.05). Majority of videos were deemed as poor or worse (91.8%) in quality. The completeness of the videos' content was also evaluated across five categories with an average score of 2.53 ± 2.1 out of the maximum 12. The DISCERN scores did not correlate with the degree of completeness of the videos (r = 0.226). CONCLUSION: BPH videos on TikTok have a wide reach, but the videos are mostly of low quality and completeness. Future videos should be made with quality and completeness in mind given the large viewership and more can be done to evaluate the extent of BPH misinformation and its impact on patients.

BACKGROUND: Transplant renal artery aneurysm (TRAA) is rare. TRAA that develops post transplantation consists of 0.10% of the vascular complications post renal transplant (Transplant Proc 41:1609-1614, 2009; Indian J Urol 29:42-47, 2013). CASE PRESENTATION: We report a case of TRAA in an asymptomatic young female. CT angiogram with detailed 3D reconstruction showed a 2.6 × 2.2 cm wide neck saccular TRAA arising from the anterior segmental branch of the graft renal artery (Figs. 2 and 3). A multidisciplinary team of interventional radiologists, vascular and urologist was involved for preoperative surgical planning and unique repair methods. Endovascular and percutaneous approaches were deemed not feasible, and an open in vivo approach with a saphenous vein graft was taken. CONCLUSION: TRAA, albeit rare, is a complication that can occur post renal transplant. In-vivo surgical repair of TRAA is feasible with a multidisciplinary approach and careful preoperative planning. Saphenous vein graft is still a versatile graft and can be used as a conduit successfully.

PURPOSE: To assess the effect of aromatherapy with lavender oil alone, and in combination with music, on pain and anxiety during extracorporeal shockwave lithotripsy for kidney stones. METHODS: This was a single-centre prospective, randomised controlled trial. The subjects were block randomised into 3 study groups, Group 1: Control; Group 2: Aromatherapy only; Group 3: Aromatherapy and music. All subjects were given patient-controlled intravenous alfentanil as standard analgesia. The primary outcome measures were pain and anxiety scores using visual analogue scale (VAS) and State-Trait Anxiety Inventory. RESULTS: Ninety patients were recruited and randomised prospectively into Group 1 (n = 30), Group 2 (n = 30), and Group 3 (n = 30). For pain outcome, both Group 2 and Group 3 showed a trend towards lower mean VAS pain scores of 2.73 in both groups compared to the control with a mean VAS score of 3.50, but it was not statistically significant (p = 0.272). There was no significant difference in anxiety scores between groups post-treatment. CONCLUSIONS: Our study was unable to show a significant improvement in pain relief and anxiety when aromatherapy with lavender oil was added to standard analgesia alone during shockwave lithotripsy. There was also no difference when aromatherapy was combined with music.

OBJECTIVE: To perform a systematic review and meta-analysis to evaluate the impact of body mass index (BMI) on oncological (primary) and surgical (secondary) outcomes of patients who underwent nephrectomy, as obesity or high BMI is a known risk factor for renal cell carcinoma (RCC) and predictor of poorer outcomes. METHODS: Studies were identified from four electronic databases from database inception to 2 June 2021, according to the Preferred Reporting Items for Systematic Review and Meta-analysis statement. The review protocol was registered in the International Prospective Register of Systematic Reviews with the identification number: CRD42021275124. RESULTS: A total of 18 studies containing 13 865 patients were identified for the final meta-analysis. Regarding oncological outcomes, higher BMI predicted higher overall survival (BMI >25 vs BMI <25 kg/m2 : hazard ratio [HR] 0.70, 95% confidence interval [CI] 0.58-0.85), cancer-specific survival (BMI >25 vs BMI <25 kg/m2 : HR 0.60, 95% CI 0.50-0.73; BMI 25-30 vs BMI <25 kg/m2 : HR 0.46, 95% CI 0.23-0.95; BMI >30 vs BMI <25 kg/m2 : HR 0.50, 95% CI 0.36-0.69), and recurrence-free survival rates (BMI >25 vs BMI <25 kg/m2 : HR 0.72, 95% CI 0.63-0.82; BMI 25-30 vs BMI <25 kg/m2 : HR 0.59, 95% CI 0.42-0.82). Those with a lower BMI fared better in surgical outcomes, such as operation time and warm ischaemic time, although the absolute difference was minimal and unlikely to be clinically significant. There was no difference between groups for length of hospital stay, intraoperative or postoperative complications, blood transfusion requirements, and conversion to open surgery. CONCLUSION: Our study suggests that a higher BMI is associated with improved long-term oncological survival and similar perioperative outcomes as a lower BMI. More research into the underlying biological and physiological mechanisms will enable better understanding of the effect of BMI, beyond mere association, on post-nephrectomy outcomes.

Introduction: Radiomics in uro-oncology is a rapidly evolving science proving to be a novel approach for optimizing the analysis of massive data from medical images to provide auxiliary guidance in clinical issues. This scoping review aimed to identify key aspects wherein radiomics can potentially improve the accuracy of diagnosis, staging, and grading of renal and bladder cancer. Material and methods: A literature search was performed in June 2022 using PubMed, Embase, and Cochrane Central Controlled Register of Trials. Studies were included if radiomics were compared with radiological reports only. Results: Twenty-two papers were included, 4 were pertinent to bladder cancer, and 18 to renal cancer. Radiomics outperforms the visual assessment by radiologists in contrast-enhanced computed tomography (CECT) to predict muscle invasion but are equivalent to CT reporting by radiologists in predicting lymph node metastasis. Magnetic resonance imaging (MRI) radiomics outperforms radiological reporting for lymph node metastasis. Radiomics perform better than radiologists reporting the probability of renal cell carcinoma, improving interreader concordance and performance. Radiomics also helps to determine differences in types of renal pathology and between malignant lesions from their benign counterparts. Radiomics can be helpful to establish a model for differentiating low-grade from high-grade clear cell renal cancer with high accuracy just from contrast-enhanced CT scans. Conclusions: Our review shows that radiomic models outperform individual reports by radiologists by their ability to incorporate many more complex radiological features.
