[Laparoscopic nephrectomies and kidney resections in children].

Objective: To present the experience of laparoscopic nephrectomies and kidney resections in children.

Material And Methods: There were 28 minimally invasive surgeries for renal tumors between July 2015 and March 2023 (92 months). There were 16 (57%) boys and 12 (43%) girls who underwent 22 nephrectomies and 6 kidney resections.

[Surgery for abdominal neuroblastoma in children].

This review is devoted to surgical approach for neurogenic tumors in children. The authors discuss epidemiological data, history of surgical approaches, preoperative imaging and risk factors. A special attention is paid to the influence of surgical interventions for various neuroblastomas on overall and event-free survival in pediatric population, as well as the most common surgical complications and modern approaches to their treatment.

[Autologous kidney transplantation in a high-risk patient with locally advanced retroperitoneal neuroblastoma].

Surgery of locally advanced neuroblastoma with risk factors is one of the most difficult in pediatric surgery. Incidence of nephrectomy during subtotal or complete tumor resection is higher due to common involvement of renal vessels. We present a patient with locally advanced retroperitoneal neuroblastoma who underwent heterotopic kidney autotransplantation.

[Bioelectrical activity of the gastrointestinal tract in acute intestinal obstruction].

During the period of 2001-2002 in the surgical department of the Republican clinical hospital there were 72 patients with acute small bowel obstruction. In addition to generally accepted methods of diagnosing the acute intestinal obstruction including general rentgenography of organs of the abdominal cavity, radiopaque methods, ultrasound scanning of organs of the abdominal cavity, a measuring-diagnostic system (polygastroenterograph "PGEG-2001") was used which registered and processed fluctuation of biopotentials of different parts of the gastrointestinal tract and measured instantaneous values of the intracavital gastric pressure. So, a short period of time was needed to reliably determine the kind and level of obstruction.
