“…To overcome this issue, nephrometric scores have been developed. Such models merge several characteristics of the mass (i.e., size, exophytic/endophitic ratio, location, rim, and proximity to the hilum) and predict the complication rate, risk of conversion to nephrectomy, and need for-or duration of-ischemia [7,8].…”

Despite the arising interest in three-dimensional (3D) reconstruction models from 2D imaging, their diffusion and perception among urologists have been scarcely explored. The aim of the study is to report the results of an international survey investigating the use of such tools among urologists of different backgrounds and origins. Beyond demographics, the survey explored the degree to which 3D models are perceived to improve surgical outcomes, the procedures mostly making use of them, the settings in which those tools are mostly applied, the surgical steps benefiting from 3D reconstructions and future perspectives of improvement. One hundred responders fully completed the survey. All levels of expertise were allowed; more than half (53%) were first surgeons, and 59% had already completed their training. Their main application was partial nephrectomy (85%), followed by radical nephrectomy and radical prostatectomy. Three-dimensional models are mostly used for preoperative planning (75%), intraoperative consultation and tailoring. More than half recognized that 3D models may highly improve surgical outcomes. Despite their recognized usefulness, 77% of responders use 3D models in less than 25% of their major operations due to costs or the extra time taken to perform the reconstruction. Technical improvements and a higher availability of the 3D models will further increase their role in surgical and clinical daily practice.

Effect of adherent perinephric fat on outcomes of nephron-sparing treatment of renal cell cancer

Introduction. Nephrometric scales have been developed to determine the appropriate surgical tactics and to predict intraoperative values more accurately, considering the characteristics of the renal tumour. However, there is a need to assess the perinephric fat. The Mayo Adhesive Probability (MAP) scale aims to identify adherent perinephric fat (APF) or 'complex' paranephric fat preoperatively.Objective. To evaluate the effect of APF on intraoperative and functional outcomes of patients with renal cell cancer (RCC) who underwent laparoscopic partial nephrectomy.Materials & methods. We analysed 118 patients with localised RCC who underwent laparoscopic partial nephrectomy. At the preoperative stage, according to the results of contract-enhanced msCT, the presence of APF was assessed using the MAP scale. At the same time, the thickness of the posterior perinephric fat was measured and the grade of its twisting was assessed. As a result, the patients were divided into two groups: group 1 MAP 0 – 2 pts (no APF) 34 patients and group 2 MAP 3 – 5 pts (presence of APF) 84 patients. In each group, the following indicators were assessed: stage according to the TNM classification, mean age and BMI, average nephrometry score according to the R.E.N.A.L. system, glomerular filtration rate (GFR).Results. The median surgery time for group 1 patients was 115.0 [92.5; 142.5] min, for group 2 — 130.0 [101.3; 180.0] min. The median warm ischemia time in patients in group 1 was 15 [0; 20] min, in group 2 — 12 [0; 18] min. The median blood loss in the groups 1 and 2 was 50 [15; 100] and 50 [0; 100] ml, respectively. The mean GFR on the first day after surgery was 63.34 ± 18.40 ml/min/1.73 m2 in group 1 and 55.09 ± 16.01 ml/min/1.73 m2 in group 2. Openings of the pyelocalyceal system were observed in 8 (23.53%) and 23 (27.38%) patients in groups 1 and 2, respectively. A positive surgical margin was detected one patient in group 1 and two in group 2. Early postoperative complications in group 1 were four patients and group 2 — 15 patients.Conclusion. The presence of APF and its severity can be effectively assessed using the MAP score, which is promising, but is limited only to the prognostic of APF without correlation with nephrometric scales that assess tumour anatomy parameters. However, the issue of developing a unified assessment system that includes APF and kidney morphometry is currently open, and the definition of APF is still subjective and requires an objective analysis to obtain more accurate outcomes.
