Laparoscopic partial nephrectomy (LPN) offers excellent cancer control for small renal masses. Recurrence and cancer-specific survival rates are high, with outcomes mainly influenced by tumor stage and grade, not surgical margins.

Area of Science:

  • Urology
  • Oncology
  • Surgical Innovation

Background:

  • Renal cell carcinoma (RCC) is a common malignancy.
  • Small renal masses are increasingly detected.
  • Laparoscopic partial nephrectomy (LPN) is a standard treatment for small renal masses.

Purpose of the Study:

  • To evaluate the oncologic outcomes of LPN for renal cell carcinoma.
  • To assess disease recurrence and cancer-specific survival after LPN.
  • To identify factors influencing outcomes in patients treated with LPN.

Main Methods:

  • Retrospective analysis of 150 patients with small renal masses treated with LPN.
  • Pathologic diagnosis of RCC in 137 patients.
  • Kaplan-Meier analysis for recurrence-free and cancer-specific survival.

Technical Modification of the Terminal Ureter During Total Transperitoneal Laparoscopic Nephroureterectomy for Upper Urinary Tract Urothelial Carcinoma

Published on: November 22, 2019

Main Results:

  • 88% of patients had pT1a disease; 6% had pT3a.
  • Median tumor size was 25 mm.
  • 2- and 5-year recurrence-free survival rates were 98% and 95%.
  • 2- and 5-year cancer-specific survival rates were 99% and 97%.
  • Positive surgical margins occurred in 1.4% of patients.
  • pT3a stage and Fuhrman grade 3 were associated with higher recurrence and mortality risks.

Conclusions:

  • LPN provides excellent oncologic control for small renal masses.
  • Recurrence and cancer-specific death are rare after LPN.
  • Outcomes are primarily linked to pathologic stage and tumor grade, not surgical margins.
