The Association of the Mayo Adhesive Probability (MAP) score with total operative time in patients undergoing hand assisted laparoscopic donor nephrectomy.

OBJECTIVE To assess whether donor kidney Mayo Adhesive probability (MAP) score is associated with (total operative time) ORT in patients undergoing hand-assisted laparoscopic donor nephrectomy (HALDN). METHODS Three hundred and thirty-one patients undergoing HALDN were reviewed. Donor kidney MAP scores were recorded based on preoperative computed tomography or magnetic resonance imaging. Single variable and multiple variable regression analysis were used to evaluate the correlation between MAP score and ORT. RESULTS Three hundred and thirty-one patients underwent HALDN between January 2007 and April 2017. Median body mass index was 26.4 kg/m(2) (interquartile range 23.4, 29.5) and median age at time of surgery was 45 years (interquartile range 37, 53). Two hundred and thirty-one patients had donor kidney MAP = 0. Hundred patients had donor kidney MAP >0. Mean ORT was 163 minutes for females with MAP = 0 and 166 minutes for females with MAP >0. Median ORT was 180 minutes for males with MAP =0 and 191 minutes for males with MAP >0. Donor kidney MAP score > 0 was significantly correlated with longer ORT (increase of 24.4 minutes, P = .001) in single variable analysis. In multivariable analysis, this correlation was only significant for males (increase of 28.9 minutes, P = .013). CONCLUSION MAP score > 0 is associated with longer ORT for males undergoing HALDN.
