“…116 Acute obstruction results in increased pelvic pressure and a decreased renal blood flow. 138 Though it appears reasonable that increased pressure is the cause of renal damage, during chronic dilation, baseline pressure is only marginally (if even) elevated and cannot be used as a diagnostic criterion. [139][140][141][142] Others have suggested that obstructive damage may be due to renal ischemia.…”

Doppler RI can be elevated in hydronephrotic kidney as a result of both partial and complete obstruction of the ureter. There are no RI differences among obstructed kidneys with different degree and different site of ureteral obstruction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
