“…The MAP scoring system, which consist of posterior perinephric fat thickness and perinephric fat stranding, can predict the occurrence of APF. There is increasing evidence that the MAP score can be used as a reliable and accurate indicator of APF, 8,10 as well as for the prediction of longer operative times, longer dissection time, and greater estimated blood loss 9,13,14 …”

“…There is increasing evidence that the MAP score can be used as a reliable and accurate indicator of APF, 8,10 as well as for the prediction of longer operative times, longer dissection time, and greater estimated blood loss. 9,13,14 Generally speaking, adrenal glands are located above the kidneys, surrounded by the perirenal fat in all populations, regardless of obesity. Considering that RLA also needs to pass through the surrounding renal environment and separate part of the perinephric fat, APF should also affect RLA.…”

Backgrounds This study aimed to determine whether the Mayo adhesive probability score (MAP), which evaluated adherent perinephric fat (APF), is useful in evaluating the difficulty of retroperitoneal laparoscopic adrenalectomy (RLA), and to analyse the correlation between MAP and perioperative parameters. Methods Clinical data of 104 patients with adrenal adenoma who underwent RLA were collected for retrospective analysis. According to the CT images obtained before surgery, patients were divided into two groups: High MAP group (2–5 points) and Low MAP group (0–1 points). Comparison of the general clinical characteristics and the perioperative data between the two groups was made. Results There were more male patients (73.7% versus 34.3%), more patients with a smoking history (24.3% versus 7.5%), higher BMI (25.7 versus 23.2, kg/m2), and bigger (23.8 versus 18.5, mm) neoplasm in the high MAP group (P < 0.05). Significant difference was observed in operative time (128.8 versus 102.3, min), estimated blood loss (47.2 versus 25.2, ml) and drainage tube removal time (4.0 versus 3.2, d) between the two groups (P < 0.05). A high MAP score (P < 0.001) and the size of tumour (P = 0.024) were independent risk factors for extended operative time. A higher BMI (OR = 1.525, P < 0.001) and larger tumour size (OR = 2.862, P = 0.004) were independent risk factors for a high MAP score. Conclusions MAP score was associated with the perioperative outcomes of RLA. BMI and tumour size were better indicators of MAP score, which can influence the difficulty of RLA.

“…Increasing evidence demonstrated that MAP score is a credible and accurate predictor of APF in partial nephrectomy (PN) [4][5][6][7][8] and donor nephrectomy (DN) [9,10]. Recent studies reported that MAP score is associated with perioperative outcomes in PN [11][12][13][14], DN [10,15,16], and Laparoscopic Adrenalectomy(LA) [17][18][19], however, the conclusion among above studies is controversial. Thus, this meta-analysis aimed to explore clinical predictive role of MAP score in patients undergoing PN, DN, and LA.…”

Purpose This study aimed to determine the clinical predictive role of Mayo adhesive probability (MAP) score in nephrectomy and adrenalectomy. Methods Publications were searched in PubMed, Web of Science, and Embase. Pooled analysis of MAP predictive role of perioperative outcomes including operative times (OT), estimated blood loss (EBL), warm ischemia time (WIT), length of stay (LOS), and complication rate was performed. Weighted mean differences (WMDs) with 95% confidence intervals (CIs) for continuous data and Odds ratio (ORs) with 95% Cis for dichotomous data were considered the effect size. Statistical significance was defined as P-value < 0.05. Results A total of 10 eligible studies including 3200 patients undergoing nephrectomy or adrenalectomy were included. Pooled results of 10 studies showed that OT in high MAP score group were significant longer than those in low MAP score group (WMD = 18.58, 95% CI: [11.44, 25.73], P < 0.00001). Pooled results of 7 studies showed that EBL in high MAP score group were significant greater than those in low MAP score group (WMD = 38.50, 95% CI: [20.44, 56.57], P < 0.0001). Pooled results of 5 studies showed that there was no significant difference on WIT between high MAP score group and low MAP score group (WMD = 0.58, 95% CI: [-0.34, 1.51], P = 0.22). Pooled results of 6 studies showed that there was no significant difference on LOS between high MAP score group and low MAP score group (WMD=-0.07, 95% CI: [-0.39, 0.25], P = 0.67). Pooled results of 7 studies showed that there was no significant difference on complication rate between high MAP score group and low MAP score group (OR = 0.79, 95% CI: [0.57, 1.11], P = 0.18). Conclusion The high MAP score predicts longer operative times and greater estimated blood loss. In other words, the MAP score could predict surgical complexity.

BackgroundIn June 2021, the first robot‐assisted donor nephrectomy (RADN) was performed at the Leiden University Medical Center (LUMC), the Netherlands. The goal of this study was to investigate whether this procedure has been implemented safely and efficiently.MethodsRADN was retrospectively compared to laparoscopic donor nephrectomy (LDN) performed during the same time period (June 2021 until November 2022). Patients were assigned to RADN depending on the availability of the da Vinci robot and surgical team. The studied endpoints were postoperative complications, operative time, estimated blood loss, warm ischemic time (WIT), and postoperative pain experience. For analysis, the Student's t‐test and Chi‐squared test were used for, respectively, continuous and categorical data.ResultsForty RADN were compared to 63 LDN. Total insufflation time was significantly longer in RADN compared to LDN (188 min (169–214) versus 172 min (144–194); p = 0.02). Additionally, WIT was also found to be significantly higher in the robot‐assisted group (04:54 min vs. 04:07 min; p < 0.01). No statistical differences were found in postoperative outcomes (eGFR of the recipient at 3‐month follow‐up, RADN 54.08 mL/min ±18.79 vs. LDN 56.41 mL/min ±16.82; p = 0.52), pain experience, and complication rate.ConclusionRADN was safely and efficiently implemented at the LUMC. It's results were not inferior to laparoscopic donor nephrectomy. Operative time and warm ischemic times were longer in RADN. This may relate to a learning curve effect. No clinically relevant effect on postoperative outcomes was observed.
