Meta-Analysis Comparative Study Review
A systematic review and meta-analysis were performed to investigate the efficacy of the AirSeal Valveless Trocar Needle Insufflation System in robot-assisted partial nephrectomy (RAPN). The study compared the differences in perioperative outcomes between the AirSeal insufflation group (AIS) and the conventional insufflation group (CIS). A systematic search of databases such as PubMed, Embase, Cochrane library, and Web of science was performed to identify studies reporting perioperative outcomes between the AirSeal insufflation group (AIS) and the conventional insufflation group (CIS) in RAPN. The study protocol is registered with PROSPERO (CRD42024524335). The primary outcome was to compare the incidence of subcutaneous emphysema (SCE) and postoperative pain scores between the two approaches. The review included four studies with 379 patients, 194 in the AIS group and 185 in the CIS group. Baseline characteristics of the two groups were similar in all outcomes. SCE was significantly lower in the AIS group than in the CIS group [(OR) 0.30 (0.16, 0.54), p < 0.001]. Postoperative 12-h pain scores were also significantly lower in the AIS group compared to the CIS group [(WMD) - 0.93 (- 1.67, - 1.09), p = 0.014]. Both groups showed a significant reduction in length of hospitalization [(WMD) - 0.12 (- 0.84, 0.60), p = 0.746], thermal ischemia time [(WMD) 4.72 (- 5.71, 15.15), p = 0.375], amount of lost hemoglobin [(WMD) - 0.19 (- 0.53, 0.15), p = 0.284], pneumothorax [(OR) 0.13 (0.02,1.10), p = 0.062], mediastinal emphysema [(OR) 0.55 (0.20, 1.46), p = 0.230], and 4-h pain score [(WMD) - 0.25 (- 1.16, 0.65), p = 0.584]; no significant differences were observed. The incidence of subcutaneous emphysema SCE and 12-h pain scores were significantly lower in the AIS group compared to the CIS group. The AirSeal system demonstrated similar efficacy and a higher safety profile than the conventional insufflation system in robotic-assisted partial nephrectomy; however, due to the lack of a randomized study on the topic, further data are needed.

Review
INTRODUCTION
Preoperative three-dimensional (3D) reconstruction using sectional imaging is increasingly used in challenging pediatric cases to aid in surgical planning. Many case series have described various teams' experiences, discussing feasibility and realism, while emphasizing the technological potential for children. Nonetheless, general knowledge on this topic remains limited compared to the broader research landscape. The aim of this review was to explore the current devices and new opportunities provided by preoperative Computed Tomography (CT) scans or Magnetic Resonance Imaging (MRI).
METHODS
A systematic review was conducted to screen pediatric cases of abdominal and pelvic tumors with preoperative 3D reconstruction published between 2000 and 2023.
DISCUSSION
Surgical planning was facilitated through virtual reconstruction or 3D printing. Virtual reconstruction of complex tumors enables precise delineation of solid masses, formulation of dissection plans, and suggests dedicated vessel ligation, optimizing tissue preservation. Vascular mapping is particularly relevant for liver surgery, large neuroblastoma with imaging-defined risk factors (IDRFs), and tumors encasing major vessels, such as complex median retroperitoneal malignant masses. 3D printing can facilitate specific tissue preservation, now accessible with minimally invasive procedures like partial nephrectomy. The latest advancements enable neural plexus reconstruction to guide surgical nerve sparing, for example, hypogastric nerve modelling, typically adjacent to large pelvic tumors. New insights will soon incorporate nerve plexus images into anatomical segmentation reconstructions, facilitated by non-irradiating imaging modalities like MRI.
CONCLUSION
Although not yet published in pediatric surgical procedures, the next anticipated advancement is augmented reality, enhancing real-time intraoperative guidance: the surgeon will use a robotic console overlaying functional and anatomical data onto a magnified surgical field, enhancing robotic precision in confined spaces.

Comparative Study Meta-Analysis
Comparison of the perioperative outcomes of robot-assisted laparoscopic transperitoneal versus retraperitoneal partial nephrectomy for posterior-lateral renal tumors: a systematic review and meta-analysis.
The study aims to assess the available literature and compare the perioperative outcomes of robotic-assisted partial nephrectomy (RAPN) for posterior-lateral renal tumors using transperitoneal (TP) and retroperitoneal (RP) approaches. Systematically searched the Embase, PubMed, and Cochrane Library databases for literature. Eligible studies were those that compared TP-RAPN and RP-RAPN for posterior-lateral renal tumors. The data from the included studies were analyzed and summarized using Review Manager 5.3, which involved comparing baseline patient and tumor characteristics, intraoperative and postoperative outcomes, and oncological outcomes. The analysis included five studies meeting the inclusion criteria, with a total of 1440 patients (814 undergoing RP-RAPN and 626 undergoing TP-RAPN). Both groups showed no significant differences in age, gender, BMI, R.E.N.A.L. score, and tumor size. Notably, compared to TP-RAPN, the RP-RAPN group demonstrated shorter operative time (OT) (MD: 17.25, P = 0.01), length of hospital stay (LOS) (MD: 0.37, P < 0.01), and lower estimated blood loss (EBL) (MD: 15.29, P < 0.01). However, no significant differences were found between the two groups in terms of warm ischemia time (WIT) (MD: -0.34, P = 0.69), overall complications (RR: 1.25, P = 0.09), major complications (the Clavien-Dindo classification ≥ 3) (RR: 0.97, P = 0.93), and positive surgical margin (PSM) (RR: 1.06, P = 0.87). The systematic review and meta-analysis suggests RP-RAPN may be more advantageous for posterior-lateral renal tumors in terms of OT, EBL, and LOS, but no significant differences were found in WIT, overall complications, major complications, and PSM. Both surgical approaches are safe, but a definitive advantage remains uncertain.

Review
The Mayo Adhesive Probability (MAP) score is a radiographic scoring system that predicts the presence of adherent perinephric fat (APF) during partial nephrectomies (PNs). The purpose of this systematic review is to summarize the current literature on the application of the MAP score for predicting intraoperative difficulties related to APF and complications in laparoscopic PNs. Three databases, PubMed, Scopus and Cochrane, were screened, from inception to 29 October 2023, taking into consideration the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Guidelines. All the inclusion criteria were met by eight studies. The total operative time was around two hours in most studies, while the warm ischemia time was <30 min in all studies and <20 min in four studies. Positive surgical margins, conversion and transfusion rates ranged from 0% to 6.3%, from 0% to 5.0% and from 0.7% to 7.5%, respectively. Finally, the majority of the complications were classified as Grade I-II, according to the Clavien-Dindo Classification System. The MAP score is a useful tool for predicting not only the presence of APF during laparoscopic PNs but also various intraoperative and postoperative characteristics. It was found to be significantly associated with an increased operative time, estimated blood loss and intraoperative and postoperative complication rates.

Review
INTRODUCTION
The aim of this review was to assess the outcomes of partial nephrectomy using indocyanine green (ICG) regarding ischemia time, positive surgical margins (PSM), estimated blood loss (EBL) and estimated GFR reduction while also suggesting the optimal dosage scheme.
MATERIAL AND METHODS
A systematic review was performed using Medline (PubMed), ClinicalTrials.gov, and Cochrane Library (CENTRAL) databases, in concordance with the PRISMA statement. Studies in English regarding the use of indocyanine green in partial nephrectomy were reviewed. Reviews and meta-analyses, editorials, perspectives, and letters to the editors were excluded.
RESULTS
Individual ICG dose was 5 mg in most of the studies. The mean warm ischemia time (WIT) on each study ranged from 11.6 minutes to 27.2 minutes. The reported eGFR reduction ranged from 0% to 15.47%. Lowest mean EBL rate was 48.2 ml and the highest was 347 ml. Positive surgical margin rates were between 0.3% to 11%.
CONCLUSIONS
Indocyanine green seems to be a useful tool in partial nephrectomy as it can assist surgeons in identifying tumor and its related vasculature. Thereby, warm ischemia time can be reduced and, in some cases, selective ischemia can be implemented leading to better renal functional preservation.

Meta-Analysis Comparative Study Review
OBJECTIVE
Which is superior, partial nephrectomy (PN) or radical nephrectomy (RN), for the treatment of complex renal tumours (RENAL or score ≥ 7)?
METHODS
This systematic review and meta-analysis was conducted in accordance with the PRISMA statement. A systematic search of the literature published before November 2023 was conducted using Pubmed, Embase, Cochran, and Web of Science libraries. We included studies comparing perioperative and oncologic outcomes of partial nephrectomy and radical nephrectomy for complex renal tumors.
RESULTS
A total of 2602 patients from six studies meeting the criteria were included. The PN group had a longer operative time, increased estimated blood loss, and major complications but a smaller reduction in renal function. There were no significant differences in complications, length of hospital stay, and blood transfusion. In terms of oncological outcomes, the PN group had longer OS, CSS, and no significant difference in RFS.
CONCLUSIONS
For complex renal tumours, PN requires more operative time and has a higher chance of complications in the short term. However, in long-term follow-up, PN has a small decrease in renal function with longer OS and CSS.

Meta-Analysis
The objective of this meta-analysis was to evaluate the perioperative outcomes of robotic-assisted partial nephrectomy (RAPN) in obese and non-obese patients. Through March 2024, we executed an exhaustive search in internationally acclaimed databases such as PubMed, Cochrane Library, and Web of Science, limiting our scope to publications in English. We discarded review articles, protocols lacking empirical data, conference abstracts, and materials not pertinent to our research. Our analytical framework utilized the Cochran-Mantel-Haenszel method alongside a random-effects model for evaluating dichotomous variables' mean differences, expressed through odds ratios (OR) with 95% confidence intervals (CI). We established statistical significance at a P value below 0.05. The comprehensive meta-analysis incorporated data from eight cohort studies, collectively assessing 3657 patients. Findings indicated that, relative to individuals of normal weight, those in the obese category had prolonged operative durations (WMD - 25.68 95% CI - 42.07 to - 9.29; P = 0.002), increased estimated blood loss (WMD - 48.55ml, 95% CI - 78.27 to - 18.83; P = 0.001), and longer warm ischemia times (WMD - 1.11, 95% CI - 2.03 to - 0.19; P = 0.02). However, no significant disparities were observed in hospital stay duration, intraoperative and total postoperative complications, severe postoperative complications, or alterations in postoperative estimated glomerular filtration rate (eGFR). Our findings conclude that robotic-assisted partial nephrectomy (RAPN) represents a viable and safe surgical approach for obese patients. This assertion is backed by the observation that crucial metrics, including postoperative renal function alterations, surgical complication rates, and hospitalization duration, exhibit no substantial variances when juxtaposed with counterparts of normal weight.

Review
Percutaneous cryoablation (PCA) can be an alternative to partial nephrectomy (PN) in selected patients with stage T1 renal tumours. Existing meta-analyses regarding ablative techniques compared both laparoscopic and PCA with PN. That is why we decided to perform a meta-analysis that focused solely on PCA. The aim of this study was to compare the complications and functional and oncological outcomes between PCA and PN. A systematic literature search was performed in January 2024. Data for dichotomous and continuous variables were expressed as pooled odds ratios (ORs) and mean differences (MDs), both with 95% confidence intervals (CIs). Effect measures for the local recurrence-free survival (LRFS), metastasis-free survival (MFS), cancer-specific survival (CSS) and overall survival (OS) were expressed as pooled hazard ratios with 95% CIs. Among 6487 patients included in the 14 selected papers, 1554 (23.9%) and 4924 (76.1%) underwent PCA and PN, respectively. Compared with the PN group, patients undergoing PCA had significantly lower overall and major postoperative complication rates. There was no difference in renal function between PCA and PN groups. When analysing collective data for cT1 renal carcinoma, PCA was associated with worse LRFS compared with PN. However, subgroup analysis revealed that in the case of PCA, LRFS was not decreased in patients with cT1a tumours. Moreover, patients undergoing robotic-assisted PN had improved LRFS compared with those undergoing PCA. No significant differences were observed between PCA and PN in terms of MFS and CSS. Finally, PCA was associated with worse OS than PN in both collective and subgroup analyses. In conclusion, PCA is associated with favourable postoperative complication rates relative to PN. Regarding LRFS, PCA is not worse than PN in cT1a tumours but has a substantially relevant disadvantage in cT1b tumours. Also, RAPN might be the only surgical modality that provides better LRFS than PCA. In cT1 tumours, PCA shows MFS and CSS comparable to PN. Lastly, PCA is associated with a shorter OS than PN.

To evaluate the effects of neoadjuvant vascular endothelial growth factor-tyrosine kinase inhibitor (VEGF-TKI) treatment on surgery in patients with renal cell carcinoma (RCC), sources from Embase, PubMed and the Cochrane Library databases collected from inception to December, 2022 were used for analysis in the present study, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data regarding surgical outcomes were collected. The pooled effect sizes were calculated in terms of the risk ratio (RR)/standard mean difference (SMD) with 95% confidence intervals (CIs) using the random-effects model. Subgroup and sensitivity analyses were used to explore the source of heterogeneity within the data. In total, 9 identified articles involving 829 patients (336 in the neoadjuvant + surgery group; 493 in the surgery group) were included in the present study, according to the criteria. The results demonstrated that there were no significant differences in blood loss (SMD=-0.11; 95% CI, -0.63-0.41; P=0.68), postoperative length of hospital stay or total length of hospital stay (SMD=0.23; 95% CI, -0.55-1.01; P=0.57) or complications (RR=1.16; 95% CI, 0.80-1.67; P=0.44) between the two groups. However, neoadjuvant therapy reduced the operation time (SMD=-0.67; 95% CI, -1.25- -0.09; P=0.02) and resulted in a greater proportion of patients choosing partial nephrectomy (RR=1.84; 95% CI, 1.47-2.31; P<0.00001). In the subgroup analysis, the blood loss was significantly lower in patients with RCC with inferior vena cava tumor thrombus in the neoadjuvant group (SMD=-1.10; 95% CI, -1.82- -0.38; P=0.003). In conclusion, the results of the present study indicated that neoadjuvant VEGF-TKI treatment in patients with RCC shortened operation time, decreased blood loss and did not cause an increase in perioperative complications. In addition, this treatment modality may encourage patients to opt for partial nephrectomy to preserve renal function.
