Ectopic left kidney means that your kidney developed in an abnormal location. It could be slightly lower than the normal location or much lower in the abdomen. It could cause a problem if the your kidney is obstructed because of the abnormal location. Obstruction would be determined if there is a mention of hydronephrosis
in your ultrasound.
Medical renal parenchymal disease means that your kidney showed abnormal color (echogenicity) on ultrasound. You may want to check your serum creatinine
and a urinalysis
to determine if you really have kidney disease. You may need to see a Urologist
or a Nephrologist
