[Zero-ischemia nephron-sparing interventions for renal tumor. do we need 3D-modeling?].

Introduction: our aim was to assess and compare a zero ischemia enucleation and enucleoresection of tumor, as well as classical partial nephrectomy. In addition, we defined a role of a three-dimensional reconstruction of the tumor for the planning of intervention.

Materials And Methods: a total of 83 patients with localized renal tumors were included in the study.

[A comparative analysis of laparoscopic and retroperitoneoscopic partial nephrectomy depending on the type of temporary and definite hemostasis].

Aim: to carry out a comparative analysis of treatment results of patients with renal tumors who were undergone to nephron-sparing surgery, depending on the type of temporary and definite hemostasis.

Materials And Methods: a total of 163 laparoscopic partial nephrectomies were performed by single surgeon from January 2015 to July 2018. The comparative analysis of treatment results of patients with renal tumors based on following parameters: tumor stage, features of the tumor site, the duration of surgery, the amount of blood loss, complications rate and grade as well as functional and oncological outcomes, depending on the type of temporary and definite hemostasis, was conducted.
