Subsequently, it enters the ureter, a slim tube connecting the kidney to the bladder. Lastly, the stone passes into the bladder and is in the end eradicated via the urethra.
Understanding this development is important for each prognosis and therapy planning. Data of potential obstruction factors alongside the ureter, for instance, permits clinicians to anticipate issues and implement acceptable interventions, resembling ache administration, medical expulsive remedy, or surgical elimination. Historic understanding of this pure course of has steadily superior medical interventions resulting in much less invasive procedures and higher affected person outcomes. This data informs selections in regards to the timing and kind of intervention wanted to facilitate stone passage and forestall long-term kidney harm.
