Introduction. During last 20 years in urology there has been a number of significant advancements, which were due to the introduction into practice and improvement of minimally invasive techniques. Development of laparoscopic surgery allowed to actively introduce these procedures in various kidney disorders, including renal tumors. Laparoscopic partial nephrectomy is also undergoing changes in order to improve the technique. Standard technique requires four or more trocars, where fourth (additional) trocar is put for the assistant. However, there is an opinion that in most cases it is possible to perform partial nephrectomy without an assistant trocar, while maintaining the safety and efficiency of the procedure and improving some perioperative outcomes. The aim of our study was to compare the safety and efficiency of the three-trocar and four-trocar techniques during transperitoneal partial nephrectomy. This article also presents the technical features of laparoscopic partial nephrectomy.
Materials and methods. Between 2021 and 2023, a total of 200 patients were included in the study comparing three- and four-trocar partial nephrectomy.
Results. There was no difference in the rate of achieving renal trifecta between the two groups. In the three-trocar group, 94 cases of renal trifecta were found, while in the four-trocar group, there were 95 patients with renal trifecta.
Conclusions. The three-trocar technique is not inferior in safety and efficiency to the standard four-trocar technique. The main advantages of the three-trocar technique are less pain, cost and post-operative scarring.
