The short-term clinical efficacy and the quality of life of patients with PHC can be improved by combining JLC with TACE. The serum OPN levels in PHC patients can reflect the curative effect of treatment and the prognosis of the disease.

The downregulation of β-ARs after ureter dilation, particularly for β1-AR and β3-AR in the muscular layer, suggests a potential compensatory mechanism involving increased contraction of the ureter to push urine through the obstruction. Thus, β-ARs may be a potential target for treatment of ureter obstruction.
