Summary

This study shows that both laparoscopic and open partial nephrectomy offer excellent 10-year oncologic outcomes for selected cT1 renal tumors. Patient factors like age and comorbidity, not surgical approach, predict long-term survival.

Kidney Transplant II: Surgical Procedure

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...

Area of Science:

  • Urology
  • Surgical Oncology
  • Nephrology

Background:

  • Open partial nephrectomy (OPN) demonstrates established long-term oncologic efficacy.
  • Laparoscopic partial nephrectomy (LPN) shows comparable outcomes to OPN at 5-7 years.
  • Long-term (10-year) outcomes comparing LPN and OPN for renal cortical tumors are presented.

Purpose of the Study:

  • To evaluate the 10-year oncologic and functional outcomes of LPN versus OPN.
  • To compare survival rates and metastasis-free survival between LPN and OPN.
  • To identify predictors of mortality and metastasis after partial nephrectomy.

Main Methods:

  • Retrospective analysis of 1,541 patients with single cT1 renal cortical tumors (≤7 cm) treated between 1999-2007.
  • Minimum 5-year follow-up; 10-year data available for 45 LPN and 254 OPN patients.

Laparoscopic Left Hemihepatectomy Combined with Caudate Lobe Resection

Published on: April 11, 2025

  • Multivariable analysis to identify predictors of mortality and metastasis.

    • Main Results:

    • At 10 years, overall survival was 77.2%. Metastasis-free survival was 95.2% (T1a) and 90.0% (T1b).
    • No significant difference in 10-year outcomes between LPN and OPN, with operative approach not predicting mortality or metastasis.
    • Predictors of mortality included age, comorbidity, and indication; predictors of metastasis included indication and recurrence-free survival.

    Conclusions:

    • Both LPN and OPN provide excellent 10-year outcomes for selected cT1 renal cortical tumors.
    • Patient factors (age, comorbidity, indication) and cancer factors (recurrence-free survival) significantly influence outcomes.
    • The choice between LPN and OPN depends on surgeon preference and experience, not long-term oncologic efficacy.
