Hydronephrosis help please?😔

Candice
Found out today I have a small amount of fluid (hydronephrosis) in my right kidney. US tech & my OB said that can happen in pregnancy if the uterus is putting pressure on the urinary tract. Of course now I'm panicking about stents & kidney failure. Someone help please?😕 I'm 19 weeks w/ a healthy baby boyÂ
