[Evaluation of different methods of hemostasis when performing laparoscopic partial nephrectomy]

Area of Science:

• Urology
• Surgical Oncology

Background:

• Partial nephrectomy is a key procedure for kidney preservation.
• Effective hemostasis is crucial during nephron sparing surgery to minimize complications.

Purpose of the Study:

• To compare the effectiveness of different hemostasis methods in partial nephrectomy.
• To evaluate the safety and reliability of hemostasis techniques in nephron sparing interventions.

Main Methods:

• Analysis of 44 partial nephrectomies using laparoscopic and lumboscopic approaches.
• Comparative assessment of physical and ligature methods of hemostasis.
• Pilot study utilizing histological assessment of parenchyma after high-frequency energy application.

Main Results:

• Physical hemostasis methods increase warm ischemia time and intraoperative blood loss.
• Difficulty in visualizing resection boundaries was observed with physical methods.
• Histological assessment revealed negative effects of high-frequency energy on kidney parenchyma.
• The ligature method proved to be the most reliable for final hemostasis.

Conclusions:

• Physical hemostasis methods are not recommended for nephron sparing surgery due to increased risks.
• High-frequency energy negatively impacts kidney parenchyma, precluding its use for hemostasis.
• The ligature method is currently the sole dependable and secure approach for achieving final hemostasis in partial nephrectomy.
