Introduction. The three-dimensional (3D) imaging during laparoscopic procedures can improve the quality of that surgeries. There is a shortage of publications about the potential benefits of 3D navigation in laparoscopic surgery with urological diseases. Radical prostatectomy (RPE) is known as the gold standard of treatment of localized prostate cancer (PC), and investigation of imaging technologies in laparoscopic surgery in PC patients is a hot topic. Aim. To compare the perioperative outcomes of laparoscopic RPE performed with 3D and two-dimensional (2D) imaging. Materials and methods. We performed retrospective analysis of perioperative outcomes in 146 patients who had undergone radical surgery with localized PC. All the patients were divided into 4 groups by the surgery features: 1) 2D imaging with the technique for neurovascular bundles preservation (TNVBP) (n=52); 2) 2D without TNVBP (n=46); 3) 3D with TNVBP (n=23); 4) 3D without TNVBP (n=25). We assessed operative time, intraoperative blood loss volume (IBLV), duration of the bladder drainage, positive surgical margin (PSM) detection rate, duration of the postoperative inpatient period, urinary continence recovery rate, erectile function recovery (EFR) rate. Results and discussion. In groups 1, 2, 3, 4 the operative time was 171,4±21,1, 168,3±23,2, 98,7±17,3, 92,2±22,2 min, and the IBLV was 294,2±62,1, 281,2±53,2, 144,2±31,7, 148,5±33,0 mL, respectively. PSM detection rate was 1,92±0,11%, 2,17±0,04% in groups 1, 2, while PSM had not been detected in groups 3, 4. In all the participants, duration of the bladder drainage was 5–7 days, and the full recovery of urinary continence was detected at both 6 and 12 months after the surgery. The postoperative inpatient period was 8–10 days in groups 1, 2, and 8–9 days in groups 3, 4. The EFR at 3 months after the surgery was detected in 38,4%, 28,3%, 34.8%, 28.0% of patients, while at 12 months it was detected in 59,6%, 41,3%, 82,6%, 56,0% of patients in groups 1, 2, 3, 4, respectively. Conclusion. We revealed the following features of perioperative period of laparoscopic RPE performed with 3D imaging compared to 2D: 1) the operative time was reduced by 42–45% (р<0,05); 2) the IBLV was reduced by 47–51% (р<0,05); 3) the PSM had not been detected; 4) there was the tendency to the shorter postoperative inpatient period; 5) the EFR rate was increased by 1,3–1,4 times (р<0,05), and the best EFR outcomes were obtained via 3D imaging together with TNVBP. Thus, our study demonstrates the advisability of usage of both 3D imaging and TNVBP during the laparoscopic RPE.
BACKGROUND: Renal cell cancer is accompanied by the development of a disorder of renal function. The parameters of homeostasis after nephrectomy in renal cell cancer are not well understood. AIM: The aim of the study is to compare the kidney functional status and parameters of homeostasis in patients with RCC after nephrectomy performed by open and laparoscopic surgery. MATERIALS AND METHODS: Eighty patients with renal cell cancer Т3N0M0 were randomized according to the surgery into the comparison group with open nephrectomy (n = 40; 50,1 3,4 years old; 18 males, 22 females) and the main group with laparoscopic nephrectomy (n = 40; 52,4 5,1 years old; 16 males, 24 females). The control group was comprises from twenty subjects without urological pathology, 2258 years old, 10 males, 10 females. Laboratory parameters of endotoxicosis, lipid peroxidation, kidney functional status, partial kidney functions, and urinary syndrome were assessed on the 1st, 3rd, 6th and 10th days after the surgery. RESULTS: The early postoperative period of nephrectomy in renal cell cancer is accompanied by the development of endotoxicosis, activation of lipid peroxidation, deterioration of the functional state of the remaining kidney, and the formation of chronic kidney disease. At the same time, both systemic indicators (toxicity index, as well as concentrations of medium-weight molecules, diene conjugates, malondialdehyde), and renal parameters (glomerular filtration rate, albumin-creatinine ratio) are associated with the method of surgery: with a laparoscopic approach, changes in these indicators are reversible and less pronounced than with open nephrectomy. CONCLUSIONS: The present study demonstrates the advantage of laparoscopic nephrectomy compared to open nephrectomy in patients with renal cell cancer.

Background. Restoring the quality of life of patients to a level comparable to that of practically healthy people is the most important task of medicine in general. At this stage of development of science, the main goal in the treatment of malignant diseases remains the preservation of life. However, now in oncological practice, methods whose potential allows not only to preserve life as such, but also to ensure the high quality of this life in all its manifestations, are acquiring greater and greater significance.The objective of the study is to compare the quality of life of persons with localized kidney cancer in the early and late periods after surgical treatment by radical nephroectomy and laparoscopic resection of renal tissue.Materials and methods. A questionnaire survey using SF-36 (Short Form-36), designed for a comprehensive assessment of the quality of life associated with health.Results. The quality of life of patients with localized kidney cancer before treatment is reduced due to a number of physical and mental nature, limiting labor, domestic and social activity and causing a feeling of dissatisfaction with their lives in general. These problems are disorders of physical, social and emotional functioning, physical pain, deterioration of general and mental health, limitations of role functioning due to physical and emotional state. After surgical treatment with laparoscopic resection, complete satisfaction of patients with the quality of their life was achieved during the first 1–3 postoperative months; after radical nephroectomy – not earlier than 1–3 years.Conclusion. One of the advantages of laparoscopic resection over radical nephroectomy is a higher quality of life of patients in the early and late periods after the intervention.
Background. Bladder cancer is the most common malignancy of the urinary tract and one of the most common neoplasias in this group. The incidence and mortality rates of the population from bladder cancer differ significantly in different geographical regions of Russia.Aim. To assess the main epidemiological indicators of malignant neoplasms of the bladder in residents of Saint Petersburg and the regions of Russia.Materials and methods. The main epidemiological indicators of malignant bladder neoplasms in Saint Petersburg, Russia and individual federal districts for the period 2012–2021 were studied: crude and standardized rates of morbidity, mortality, prevalence, age structure of patients, the number of cases of diagnosis of the disease at various stages, indicators of one-year mortality and 5-year survival, data on completed cases of treatment of bladder neoplasms. Sources of information: Form No. 7 “Information on cases of malignant diseases” and the database of the Medical Information and Analytical Center (Saint Petersburg).Results. During the period 2012–2021 in Russia, there was an increase in the incidence and prevalence of malignant neoplasms of the bladder. At the same time, mortality rates decreased, and 5-year survival rates increased. This fact indicates the effectiveness of the treatment of patients in this category. In more than 50 % of cases, the disease was detected at stage I of the pathological process, which is due to the proper level of diagnosis. The main medical and statistical indicators in patients with malignant bladder neoplasms in Saint Petersburg are comparable to the average Russian data, and in a number of parameters they exceed them.Conclusion. Oncourological assistance to the population with malignant neoplasms of the bladder in Saint Petersburg is provided properly. The study of medical and statistical indicators in dynamics can be used to improve the algorithms of medical and diagnostic care for cancer patients.
