Bilateral Hydronephrosis

Bilateral hydronephrosis is the buildup of urine that dilates and distends both kidneys, usually because something impedes their emptying toward the bladder. Because it affects both kidneys at once, it requires careful attention to protect their function.

Common causes: obstructions in the urinary tract, stones, congenital abnormalities, or problems that impede the flow of urine.

Possible manifestations: pain in the lower back or abdomen, changes in the amount of urine, repeated urinary tract infections; sometimes it is discovered on imaging studies without clear symptoms.

Which specialist treats it? Its workup falls to the nephrologist and the urologist, and in children to the pediatric nephrologist and the pediatrician, with support from the internist when other conditions coexist. If you notice persistent urinary problems, the best course is to raise the case with one of these professionals.
