I typed this whole page out, & when I hit ask a question it all disappeared. I don't have the energy to retype it. Basically I wonder what it means when I have a left kidney that mensures 8.5cm & a right that measures 10.2. I have constant discomfort on my left side. This has been going on for some time. The Doctor says that my kidneys are fine, even though a mass showed on a previous ultra sound. Could the new ultra sound be incorrect, being the tech did not even measure the width or thickness. The Doctor reading the report made no mention of the different sizes either. The report does say that I have a 14cc post void residual and there is a small amount of free fluid in the cul-de sac. My research on the internet says that the 8.5cm kidney or less usually indicates irreversable kidney damage. Does anyone know if this is true? Any info would be appreciated I am tired or being in discomfort & tired all the time, not to mention all the other medical problems I am having. Thanks Baffled

Current medical status: spirometry test, showed a problem with my lungs. Just completed a heart monitor for 5 weeks waiting for results. Alot of heart palpations"

Having one kidney smaller than the other doesn’t always mean that the kidney is damaged. Smaller kidneys can function as normal as the bigger one and the discrepancy in size is fairly normal. An ultrasound scan can measure the exact kidneys’ dimensions and can visualize some features of their anatomic structure (cortex, medulla and calyx) to indirectly make judgments about the kidney’s function. A better test, however, for evaluating the function of each kidney separately is called an Intra-venous pyelography (IVP). You can consult a nephrologist about this exam and request a visit to the doctor's office.
