Newborn one kidney

My brother was born with 2 but had to get one taken out right after he was born due to it not working. He’s 25 now and has played sports he’s not suppose to and he’s just fine. No health problems!

I had a baby with no kidneys. Bilateral Renal Agenesis. It was found at my anatomy scan at 18 weeks. No amniotic fluid, heart hardening, lungs wouldn't develop, would be malformed. They said he would last two minutes outside of the womb and would suffocate to death. I decided not to go full term. I had a potassium chloride shot injected to stop his heart. I then had an induced labor, 12 hours and almost bled out. Luckily they did not have to do the d&c they were threatening to do if I bled anymore. I hid the bloody towels. Didn't care if I died, I just wanted him to come out whole for the only dignity he had left. They said it's was a fluke since it wasn't genetic.

My friend has 1 kidney! She just has to watch her diet so she doesnt get kidney infections/ stones or UTI! She perfectly fine , going now 26 years old !

My husband has one kidney, he's 25 and has never had an issue.

Don't have the same situation, but I know a handful of adults who live fine with just one.

My nephew is 13 and was having other issues and had Ct scan done this past year. We just found out he only has one kidney. All the ultrasounds they totally missed that he only had one. Anyway he is completely healthy and has no issues with only having one. Try not to worry to much!
