Improving postoperative renal function thanks to 3D virtual model guidance: a step towards in minimally invasive partial nephrectomy

Materials & Methods: 100 patients treated with minimally-invasive PN were prospectively enrolled. Inclusion criteria were the availability of contrast-enhanced CT from which a 3DVM was obtained, baseline and 3rd-month postoperative renal scan. These patients were then compared with a control group of 251 patients underwent minimally-invasive PN with the same renal function assessments but without 3DVMs. Weighteddifferential values of preoperative and 3rd-month postoperative renal can based estimated renal plasmatic Wow (ERPF) was calculated, according to the availability of 3DVMs and PADUA risk category (6-7 vs. 8-9 vs. >10). Multivariable logistic regression (MLR) models predicting a significant loss of renal function (defined as ERPF drop > 20%) were performed, overall and according to each PADUA risk category.
