“…Существенное значение в прогнозировании осложнений при нефронсберегающей хирургии, особенно выполняемой с использованием видеоэндоскопического доступа, имеет применение различных нефрометрических шкал, таких как RENAL, PADUA, C-index [23,24].…”

Лапароскопическая резекция почки (ЛРП) при лечении небольших опухолей почки получила большое распространение, однако операция связана с тепловой ишемией почки, что неблагоприятно сказывается на функциональном состоянии оперированного органа. Ведутся исследования методов резекции почки с уменьшением или полным отсутствием тепловой ишемии, в том числе с использованием лазерной энергии.

Aim: The purpose of the study is the development and evaluation of the informativeness of the author’s 3D nephrometric score application to predict the probability of intraoperative and postoperative complications in kidney operations. Material and methods: The study includes 264 patients who underwent surgical treatment of renal tumors, before that CT and 3D modeling were carried out. All patients underwent an analysis of the surgical intervention complexity on the C-index, PADUA, R.E.N.A.L., and developed 3D nephrometric score. To determine the set of variables that allow to classify patients, the method of discriminant analysis was used to predict the nature, volume of blood loss, duration of ischemia, and the number of complications. The sensitivity and specificity of the predictors were estimated with the help of ROC analysis. Results: Indicators have been established to classify patients according to the probability of complications, the amount of blood loss and the duration of ischemia during surgery for kidney cancer. We have created linear models that predict the development of bleeding during surgery, the volume of blood loss of more than 200 ml and the duration of ischemia more than 20 min, as well as the likelihood of complications using discriminant functions. The proposed author’s nephrometric score exceeds the capabilities of C-index, PADUA, R.E.N.A.L in many ways in blood loss and time of ischemia predicting, which allows us to recommend it for the assessment of resectability in kidney operations.

Background. Since partial nephrectomy and radical nephrectomy demonstrate comparable oncological safety, nephronsparing surgery is the method of choice in patients with stage T1-T2aN0M0 renal cell carcinoma.Objective: to compare the main perioperative parameters and short-term functional outcomes of treatment for localized stage cT1aN0M0 and cT1b-T2aN0M0 renal cell carcinoma.Materials and methods. A total of 148 laparoscopic partial nephrectomies were performed at N.I. Pirogov City Clinical Hospital No. 1, N.I. Pirogov Russian National Research Medical University between 2016 and 2020. Study participants were divided into two groups. Group 1 included patients with stage cT1aN0M0 tumors (n = 89; 60.1 %), whereas group 2 comprised patients with stage T1b-T2aN0M0 tumors (n = 59; 39.9 %).Results. The duration of surgery was 120 min (range: 90-150 min) in group 1 and 145 min (range: 120-170 min) in group 2 (p = 0.001). The median time of warm ischemia was 13 min (range: 7-17) and 15 min (range: 12-19 min) in groups 1 and 2, respectively (p = 0.002). Seven individuals from group 1 (7.9 %) and 12 individuals from group 2 (22.3 %) had their pelvicalyceal system lanced. The median glomerular filtration rate calculated using the MDRD (Modification of Diet in Renal Disease) formula was 56.4 mL/min/1.73 m2 in group 1 and 54.3 mL/min/1.73 m2 in group 2 (p = 0.252). Three patients in group 1 (3.4 %) had positive resection margin. The median follow-up time was 21 months.Conclusion. Nephron-sparing surgeries are an acceptable option for patients with stage cT1b-T2aN0M0 tumors in terms of their oncological and functional safety. Tumors exceeding 4 cm were associated with an increased risk of disease progression.
