The initial step to treat a stone-related condition includes:

Maintaining hydration is critical as the initial step in the management of stone-related conditions, such as urinary calculi. Adequate hydration helps dilute the urine and can facilitate the passage of small stones through the urinary tract. It may also prevent the formation of new stones by reducing the concentration of stone-forming substances in the urine.

In many cases, simply increasing fluid intake can alleviate mild symptoms and promote the expulsion of stones without the need for more invasive measures. This conservative approach is often preferred initially, especially for patients with small stones or those who are asymptomatic.

The other interventions like dialysis, surgery, or removing the stone are typically considered based on the size of the stone, the severity of the symptoms, or if there are complications, but they are not the first steps in managing most stone-related problems. Thus, the emphasis on hydration is vital in the initial approach to treatment.
