Summary

Laparoscopic partial nephrectomy using microwave tissue coagulators (MTC) for renal tumors is safe and effective. This technique demonstrated good cancer control and preserved kidney function in patients with renal cell carcinoma (RCC).

Area of Science:

  • Urology
  • Surgical Oncology

Background:

  • Renal cell carcinoma (RCC) management often involves partial nephrectomy to preserve renal function.
  • Minimally invasive techniques like laparoscopic partial nephrectomy are increasingly preferred.
  • The use of microwave tissue coagulators (MTC) in non-ischemic partial nephrectomy requires evaluation for safety and efficacy.

Purpose of the Study:

  • To assess the surgical outcomes, perioperative complications, and residual renal function.
  • To evaluate the oncological control and safety of laparoscopic non-ischemic partial nephrectomy using MTC.
  • To determine the utility of MTC in preserving renal function during partial nephrectomy.

Main Methods:

  • Retrospective investigation of 49 patients undergoing laparoscopic non-ischemic partial nephrectomy with MTC.
  • Analysis of surgical outcomes, including positive surgical margins and local recurrence.
  • Assessment of perioperative complications such as urine leakage.
  • Evaluation of residual renal function post-surgery.
  • Mean follow-up period of 32.0 months.

Main Results:

  • Histological diagnosis included RCC in 38 patients.
  • A positive surgical margin was observed in 2.0% of cases.
  • One patient experienced postoperative urine leakage, managed conservatively.
  • Local recurrence occurred in 4.1% of patients during follow-up.
  • No deterioration of residual renal function was observed.

Conclusions:

  • Laparoscopic non-ischemic partial nephrectomy using MTC is a safe and useful surgical option.
  • The technique provides effective cancer control for renal tumors.
  • MTC facilitates preservation of renal function during laparoscopic partial nephrectomy.
