One of the primary benefits of partial resection is the preservation of organ function. For instance, in the case of a partial hepatectomy (liver resection), a significant portion of the liver can regenerate, allowing it to continue performing its vital functions. Similarly, partial nephrectomy (kidney resection) helps in preserving kidney function, which is crucial for patients with only one functional kidney. Another benefit is the potentially reduced recovery time and fewer complications compared to more extensive surgeries.
