Correlation Between the Mayo Adhesive Probability Score and the Operative Time in Laparoscopic Donor Nephrectomy. In Transplantation Proceedings.

The Mayo Adhesive Probability (MAP) score predicts APF accurately. The aim of this study is to identify the association between MAP score and operative time in LDN. Methods: We retrospectively evaluated 154 kidney donors who underwent surgery from December 2017 to December 2019 at İstanbul Aydın University Hospital and İstinye University Hospital. All of the operations were done by 3 senior surgeons by a fully laparoscopic method. The MAP score was derived from computed tomography scans by 1 blinded reader. Demographic data, body mass index (BMI), MAP score, side selection, estimated glomerular filtration rate (eGFR), number of arteries and veins, operative time, hospital stay, and complications are recorded. Single and multiple variable analyses were used to evaluate the correlation between operative time and MAP score, BMI, side selection, and number of vascular structures. Results: A total of 154 patients (79 men, 75 women) with a mean age of 44.4 ± 12.72 were included in this study. None of the cases were converted to open nephrectomy. There were no major complications. Mean BMI was 27.59 ± 4.32 kg/m2, mean MAP score was 0.69 ± 1.15, and mean operative time was 40.25 ± 9.81 minutes. Although mean BMI was higher in women (28.19 ± 4.52 vs 27.03 ± 4.07; P < .05), mean MAP score was lower than in men (0.35 ± 0.86 vs 1.03 ± 1.29; P < .001). Older age, higher BMI, higher MAP score, and presence of multiple renal arteries were associated with longer operative time of LDN. The MAP score was associated with older age, male sex and higher BMI. Conclusions: This study showed that different risk factors can affect operative time in LDN. The MAP score was significantly associated with longer operative time, especially in men, so it can be useful for predicting surgical difficulty in kidney donors.eninfo:eu-repo/semantics/closedAccessArticle33272653WOS:0006342418000042-s2.0-85097090677Q410.1016/j.transproceed.2020.10.013Q3
