Kt/V is a key method used to assess the adequacy of dialysis, specifically indicating how effectively the treatment removes toxins from the blood. This measurement takes into account the volume of blood that is cleared of urea (a waste product) during the dialysis session as well as the total body water. The 'K' represents the dialyzer clearance rate of urea, 't' refers to the time of dialysis, and 'V' symbolizes the volume of distribution of urea in the body. A higher Kt/V value indicates more effective dialysis and improved clearance of urea.

Monitoring Kt/V helps ensure that patients receive sufficient dialysis to prevent the accumulation of urea and other toxins, which can lead to adverse health effects if not adequately managed. In clinical practice, targeting a Kt/V value of at least 1.2 for thrice-weekly hemodialysis treatments is generally recommended, making it a critical parameter for evaluating and ensuring the quality of dialysis therapy.
