Summary
Renal-sparing surgery is a feasible option for localized kidney tumors, even with a healthy contralateral kidney. This approach offers a viable treatment alternative, demonstrating comparable survival rates to other methods.
Area of Science:
- Urology
- Oncology
- Surgical Oncology
Background:
- Controversy exists regarding the use of renal-sparing surgery in kidney cancer patients with a functioning contralateral kidney.
- This study addresses the debate by reviewing outcomes of conservative kidney surgery.
Purpose of the Study:
- To review the recent experience and outcomes of renal-sparing surgery for kidney tumors at Royal Prince Alfred Hospital (RPAH).
- To evaluate the feasibility and efficacy of conservative kidney surgery in selected patients.
Main Methods:
- Retrospective review of 18 consecutive patients undergoing conservative kidney surgery between February 1987 and January 1995.
- Patients had either imperative (n=11) or elective (n=7) indications for surgery.
- Surgical techniques included modified enucleation, partial nephrectomy, and wedge resection, with follow-up ranging from 9 to 104 months.
Main Results:
- 16 of 18 patients survived with no evidence of metastasis at follow-up (mean 46.2 months).
- Tumor resections were complete with significant margins (mean 8.7 mm).
- Survival rates were comparable to existing literature.
Conclusions:
- Conservative surgery is indicated when radical surgery would result in an anephric state.
- Renal parenchyma-preserving surgery is a feasible treatment option for localized kidney tumors.
- The study supports conservative surgery as a viable approach even in patients with a normal contralateral kidney.
