title: The impact of renal surgery on global renal function and non-oncologic morbidity.
abstract: Nephron preservation has been increasingly prioritized in the treatment of small renal tumors. Radical nephrectomy is now understood as a risk factor for development of chronic kidney disease, which is known to increase the risk of cardiovascular events and all-cause mortality. Indications for nephron-sparing surgery (NSS) have broadened from solitary kidney, bilateral tumors, and hereditary tumor syndromes to essentially all small renal tumors. Laparoscopic NSS has demonstrated excellent cancer control as well as good functional preservation despite the need for warm ischemia. There has been ongoing debate regarding safe parameters for warm ischemia, which are thought to vary with patient factors. Focal ablative therapies have been developed for use in high-risk surgical candidates (eg, radiofrequency ablation, cryoablation) to minimize renal and other treatment-related morbidity. Emphasis on minimally invasive approaches and advances in preventing renal dysfunction and other morbidity after NSS will guide the future of these therapies.
