Intraoperative Ultrasound – an Innovative Approach to Assessing the Possibility of Laparoscopic Partial Resection for Kidney Tumours

Abstract

Intraoperative ultrasonography is an advanced diagnostic tool used in laparoscopic procedures for renal tumours. It helps surgeons make decisions between organ-sparing and radical surgeries by identifying small or deeply situated renal lesions and assessing the extent of resection needed for complete tumour removal while preserving kidney tissue. Additionally, it assists in evaluating the potential impact on the renal hilum or collecting system.

The primary objective of this investigation is to assess the value of intraoperative echography in the decision-making process regarding the choice of a specific surgical technique. Additionally, this study aims to understand how this decision would impact the subsequent surgical, functional, and oncologic outcomes.

A retrospective and prospective analysis was performed using intraoperative ultrasound on 27 cases involving partial kidney resection or radical nephrectomy. The study evaluated surgical outcomes, such as operative time, warm ischemia time, and blood loss. The findings revealed that 4 cases were converted from partial resection to radical nephrectomy based on intra-abdominal ultrasound findings. There are promising results regarding surgical margin integrity and the level of preserved renal function.

Intraoperative echography is a crucial tool for modern urologists, as it is linked to improved intraoperative, early postoperative, and long-term functional and oncological outcomes. It is an innovative method that combines the advantages of laparoscopic surgery with the high diagnostic value of ultrasound examination [1].
