Partial nephrectomy is effective for larger renal tumors (>4 cm), preserving kidney function. This kidney-sparing surgery offers good local tumor control for select patients.

Area of Science:

  • Urology
  • Nephrology
  • Oncology

Background:

  • Partial nephrectomy (kidney-sparing surgery) is increasingly considered for renal tumors.
  • Indications are being extended to include larger tumors, previously treated with radical nephrectomy.

Purpose of the Study:

  • To evaluate the preliminary results of partial nephrectomy for renal tumors greater than or equal to 4 cm.
  • To assess the feasibility and outcomes of extending kidney-sparing surgery to larger renal masses.

Main Methods:

  • A retrospective review of 39 patients who underwent partial nephrectomy for renal cortical tumors >4 cm between July 1989 and October 2001.
  • Evaluation included tumor characteristics, perioperative renal function, and postoperative complications.

Main Results:

  • The median tumor size was 5 cm, with clear-cell carcinoma being the most common histology (51%).
  • At a median follow-up of 13 months, 92% of patients had no evidence of disease.
  • 70% of patients maintained normal postoperative renal function, with significant preservation in those with preoperative dysfunction.

Conclusions:

  • Partial nephrectomy is an effective treatment for renal cortical tumors >4 cm in diameter when patients are carefully selected.
  • This approach achieves local tumor control while maximizing renal function preservation.
