Renal masses are increasingly being diagnosed due to the widespread use of cross-sectional imaging. Small asymptomatic renal masses, accounting for a majority of new diagnoses, have become a common challenge in urology. Active surveillance has emerged as a key strategy in managing these small renal masses. However, the impact of delaying surgery on the feasibility and outcomes of subsequent interventions has been a topic of debate in the medical community.
A retrospective study presented at the American Urological Association (AUA) annual meeting by Michael Wang, MD, aimed to address the question of whether delaying surgery for small renal masses had any negative effects on nephron-sparing interventions. The study included a large cohort of patients with small renal masses, comparing those who underwent immediate surgery versus those who had delayed intervention, defined as more than 90 days after initial assessment.
The analysis revealed that a similar proportion of patients in both groups underwent nephron-sparing interventions. There were no significant differences in perioperative complications, surgical outcomes, or survival between patients who had immediate surgery and those who had delayed intervention. These findings suggest that delaying surgery for small renal masses does not compromise the feasibility or outcomes of subsequent interventions.
The study’s results have important implications for the management of small renal masses. The data presented by Wang at the AUA meeting provide reassurance that putting patients on active surveillance does not have any significant downsides. This information is valuable for physicians and patients considering the best approach for the management of small renal masses.
One limitation of the study highlighted by an audience member was the definition of delayed intervention as a minimum wait of 90 days. Considering the slow growth rate of these lesions, a longer timeframe for defining delayed intervention could be explored in future research. Additionally, further studies may investigate the impact of delaying surgery on long-term outcomes and quality of life for patients with small renal masses.
The study by Wang and colleagues provides evidence that delaying surgery for small renal masses does not have an adverse effect on the feasibility or outcomes of nephron-sparing interventions. This information adds to the growing body of literature supporting the use of active surveillance as a safe and effective approach in the management of small renal masses. Future research may further explore the optimal timing of interventions and long-term implications of delaying surgery in this patient population.
