Welcome to EmpowHER and thanks for your question. Hydronephrosis may be unilateral involving just one kidney or bilateral involving both. The most common reason to have unilateral hydronephrosis is a kidney stonethat causes obstruction of the ureter. Urine will back up and cause the kidney to swell.
I have attached a link that might be helpful on hydronephrosis. Hope this helps.
