Summary

Laparoscopic and open partial nephrectomy offer similar long-term oncological outcomes for small renal tumors. Both surgical approaches demonstrate excellent metastasis-free survival at 7 years.

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...

Tumor Rupture During Partial Nephrectomy: More Questions than Answers.

European urology open science·2025

Area of Science:

  • Urology
  • Surgical Oncology
  • Nephrology

Background:

  • Open partial nephrectomy (OPN) has established long-term oncological efficacy.
  • Long-term outcomes for laparoscopic partial nephrectomy (LPN) require further investigation.

Purpose of the Study:

  • To compare the long-term oncological outcomes of LPN versus OPN.
  • To evaluate survival and recurrence rates in patients with cT1 renal cortical tumors (≤7 cm).

Main Methods:

  • Retrospective analysis of 2,246 patients undergoing partial nephrectomy (1999-2008).
  • Minimum 7-year follow-up data available for 77 LPN and 310 OPN patients.
  • Survival and recurrence data collected from medical records and patient contact.

Main Results:

Laparoscopic Anatomical Liver Segment VII Resection with Liver Parenchymal Transection Following a Priority Approach

Published on: May 23, 2025

  • Median follow-up was 4.0 years for LPN and 5.7 years for OPN.
  • No significant difference in 7-year metastasis-free survival between LPN (97.5%) and OPN (97.3%).
  • Advancing age, comorbidity, and renal dysfunction predicted mortality, not operative approach or tumor size.

Conclusions:

  • LPN and OPN provide comparable long-term overall and cancer-specific survival for cT1 renal cortical tumors.
  • Both approaches yield excellent oncological outcomes at 7 years, with high rates of metastasis-free survival.
