Intuitive, a leader in minimally invasive care and robotic-assisted surgery, has announced the findings of India's largest collaborative and multi-institutional study on robotic-assisted partial nephrectomy (RAPN) using the da Vinci surgical system. Conducted in collaboration with 14 government and private centers across India, the study validates the efficacy and safety of RAPN for renal mass surgery, providing significant insights from 800 patient cases over the past 12 years.

The retrospective study aimed to substantiate the value and benefits of using the da Vinci surgical system in RAPN, particularly in the Indian context. It sought to evaluate the procedure's efficacy and safety across diverse patient demographics and tumor complexities, offering a comprehensive overview of its clinical outcomez.

Perioperative Outcomes: The study revealed that RAPN using the da Vinci system resulted in favorable perioperative outcomes. The median operative time was 180 minutes, with a median estimated blood loss of 100 ml. The mean warm ischemia time (WIT) was 22.7 minutes. Notably, the conversion rate to open surgery was remarkably low at 0.4 percent, and the majority of complications were minor.

Functional Outcomes: Postoperative functional outcomes were promising, with mean serum creatinine and estimated glomerular filtration rate (eGFR) levels stabilizing effectively. The trifecta (achievement of negative surgical margins, no perioperative complications, and preservation of renal function) and pentafecta (trifecta plus other quality indicators) outcomes were achieved in 61.4 percent and 60 percent of patients, respectively. These metrics underscore the procedure's efficacy in preserving renal function.

Comparative Analysis: The study's outcomes were comparable to international benchmarks, aligning well with previous multicentric analyses. This reinforces the procedure's applicability and success across centers with varying volumes and levels of surgeon expertise.

The results of this extensive study demonstrate strong support for RAPN as an advanced and effective surgical option for renal mass surgery. The findings not only highlight the safety and efficacy of the da Vinci surgical system but also reinforce its value to the broader healthcare community. By providing real-world evidence from diverse clinical settings, the study underscores the potential of robotic-assisted surgery to enhance patient outcomes and streamline surgical procedures.
