Is There Any Need To Terminate Pregnancy If Undergoing Kidney Treatment?

My wife has been udergoing kidney treatment from past two weeks,when we didthe blood and urine tests theCreatinene level showed as 2.4 and protein loss showed as +++, so Neprologist asked us to take 10 PIPtaz IV inj twice a day and we followed the same. Yesterday we did the blood and urine tests again but see no difference in creatine and protein levels, though a there is a slight improvement in pus cell level. Now the doc is referring for Biopsy to examine further, but yesterday we also did pregnancy test and also met a Ganacologist and make her speak to our Neprologist. They are suggesting to terminate the pregnancy as there might be risk involved to both child and mother.Alkso they are saying Kidnay problem can not be effective diagnoised neither Biopsy can be performed under this circumstances. Pls advise if terminating pregnancy is a must here
