Partial nephrectomy in elderly patients: a systematic review and analysis of comparative outcomes

Abstract

Purpose

The management of renal masses in the elderly population is particularly challenging, as these patients are often more frail and potentially more susceptible to surgical morbidity. This review aims to provide a comprehensive analysis of the outcomes of partial nephrectomy (PN) for treating renal masses in elderly individuals.

Methods

A systematic electronic literature search was conducted in May 2024 using the Medline (via PubMed) database by searching publications up to April 2024. The population, intervention, comparator, and outcome (PICO) model defined study eligibility. Studies were deemed eligible if assessing elderly patients (aged 70 years or older) (P) undergoing PN (I) with or without comparison between a different population (non-elderly) or a different treatment option (radical nephrectomy, ablation or active surveillance) (C) evaluating surgical, functional, and oncological outcomes (O).

Results

A total of 23 retrospective studies investigating the role of PN in elderly patients were finally included. PN emerged as a safe procedure also for older patients, demonstrating good outcomes. Preoperative evaluation of frailty status emerged to be paramount. Age alone was discredited as the sole reason to reject the use of PN. The main limitation is the retrospective nature of included studies and the lack of the assessment of elderly patients’ frailty.

Conclusions

The surgical treatment of renal masses in older patients is a challenging scenario. PN should be chosen over RN whenever possible since it can better preserve renal function. The use of minimally invasive techniques should be favored in this extremely fragile group of patients.
