[Texture analysis of 3D models for the prediction of the grade of clear cell renal cell carcinoma of the kidney (pilot study)].

Aim: To evaluate the possibilities of textural analysis of 3D models in differentiating the degree of nuclear dysplasia of the clear cell renal cell carcinoma (ccRCC).

Materials And Methods: The specimens after surgical treatment of 190 patients with ccRCC were analyzed. In all cases, nephron-sparing surgery (NSS) was performed through laparoscopic access.

[Use of intelligent analysis in urology].

The main methods of intellectual analysis (IA) used in modern medicine are described in the review. The main areas for IA application in the healthcare are diagnostics, treatment, prognosis of the course and efficiency of treatment in various diseases. The IA is based on mathematical methods and algorithms.

3D modeling in adherent perinephric fat prediction in nephron-sparing surgery planning in patients with localized renal neoplasms.

Study Objective: To develop a 3D-image based morphometry scoring system for Adherent Perinephric Fat (APF) prediction in nephron-sparing surgery in renal neoplasm patients.

Materials And Methods: The retrospective study involved 391 patients who underwent a laparoscopic partial nephrectomy performed by five surgeons from January 2014 till December 2018. The surgery involved the 3D virtual operation planning with «Amira» 3D modeling software.

[Analysis of the learning curve in laparoscopic partial nephrectomy in patients with localized renal parenchymal lesions depending on the nephrometric score].

Aim: to analyze the learning curve of surgeons while performing laparoscopic partial nephrectomy in patients with localized renal parenchymal lesions by calculating the MIC (negative surgical margin, ischemia, and complications) index depending on tumor complexity according to the R.E.N.

A prospective study of novel mathematical analysis of the contrast-enhanced computed tomography vs renal scintigraphy in renal function evaluation.

Purpose: whilst renal scintigraphy (RS) can be associated with interobserver variability, it remains the standard method of evaluating split renal function.

Aim: to compare the efficacy of the novel technique of kidney function assessment and renal scintigraphy.

Method: for this prospective single-arm study we recruited patients who were recommended dynamic renal scintigraphy with mTc-DTPA (diethylenetriaminepentacetate).
