Nephroptosis : Nephroptosis is also called a “sagging kidney”. The kidney could be floating or loose and as a result it can drop down lower in the abdominal cavity. Nephroptosis can be asymptomatic or it can cause problems like urinary tract infections (having a urgent need to go or having to urinate more often). Sometimes it can be a cause for nausea, vomiting, constipation or a full or heavy feeling abdomen. Sometimes it can even lead to problems with sleep or dizziness. It is good that you are having him thoroughly evaluated.
