My husband has just found out he may have one kidney he s 49 years old and thought he had two, he also has arthritis since he was 17 years old is there conditions that could cause him to have one kidney later in life or is there just birth defects that creates him to only have one kidney
Hi, The chance of congenital absence of one kidney is more. So the problem might be since birth.  Infection of kidney like chronic infection can lead damage to kidney and loss of its portion, but total absence of one kidney could not be due to that.  The surgical removal or congenital absence seems most likely.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
