In the context of the story of the doctor's nephew, how does Chapter 34 portray the power of Udi compared to conventional medicine?

Chapter 34 starkly contrasts the power of Sai Baba's Udi with the limitations of conventional medicine. The chapter details how the doctor's nephew was afflicted with a bone-cyst (Hadyavran), and despite the efforts of his own physician uncle, other doctor friends, and even expert surgeons, the disease showed no improvement. The text explicitly states that all native and foreign treatments, including surgery, were tried and failed. It was only after these worldly remedies were completely exhausted that the family turned to Sai Baba. The Udi is presented as the ultimate solution that succeeds where all medical science felt helpless, capable of completely uprooting the pain from a seemingly incurable disease.
