The only treatment in case of uremia is

The correct option is kidney transplant.

Understanding Uremia:
Uremia is a clinical syndrome that occurs during the terminal stages of kidney failure. It is characterized by the accumulation of urea and other nitrogenous waste compounds in the blood that are normally excreted by healthy kidneys.

Why Kidney Transplant is the Ultimate Treatment:
Although dialysis (hemodialysis or peritoneal dialysis) is commonly used to artificially filter waste products from the blood, it is a temporary supportive measure and not a permanent cure. Dialysis must be performed regularly and does not restore the endocrine and metabolic functions of a normal kidney. A kidney transplant is considered the only definitive, long-term treatment for uremia because it replaces the non-functioning kidneys with a healthy, functioning donor kidney, thereby fully restoring normal renal function and freeing the patient from continuous dialysis dependency.

Analysis of Other Options:
1. Dialysis: This is a life-sustaining, temporary filtering process rather than a permanent cure or ultimate treatment for the underlying kidney failure.
2. Lithotripsy: This is a procedure that uses shock waves to break up kidney stones into smaller pieces so they can pass through the urinary tract. It does not treat renal failure or uremia.
3. Lung transplant: This surgical procedure replaces diseased lungs with healthy donor lungs and has no therapeutic connection to renal system filtration failure.
