Patient Question: Disease: Is it polycystic kidney? Description of disease: I am male, 30 years old, neither of my parents have polycystic kidney, I had an enhanced CT in August 2008, and found that there is only one cyst in each of the left and right kidney, both between 1cm and 2cm. After that, ultrasound was done every year, basically. This year, the ultrasound found that the right kidney is still a cyst, but the left kidney seems to have added another cyst, but the doctor said he was not sure, so an MRI was done on 5013.5.4, and the results were: the right kidney was found to have a cyst, the size of which was between 1cm and 2cm, and the left kidney not only had the original one that was between 1cm and 2cm, but the doctor said there seemed to be three other very small cysts (a few millimeters), in addition, I I found a few small stones in my kidney when I had an ultrasound, and I found that my blood pressure was elevated 3 years ago, the high pressure was never high, just low pressure was around 100, but low pressure was sometimes normal. I hope to help: 1. I don’t know how the MRI of both kidneys done in the hospital, whether the scan of both kidneys is complete (how I feel that only half of both kidneys are scanned, the lower level of both kidneys are not scanned, could there be other cysts in the kidneys, but the film does not show them because they are not scanned completely). Also, I don’t know if these MRI films are clear when I take the camera. 2. The enhanced CT in 2008 only found 2 kidney cysts, and the ultrasound has been basically the same for several years, but now the MRI found 3 small cysts (less than 1cm) in the left kidney, could these small cysts existed long ago, but the CT in 2008 was not as sensitive as the MRI now and they were not found? Maybe I can only find two cysts if I have another CT now, is that possible? 3. If I am not sure that I am suffering from polycystic kidney based on the above imaging data alone, then combined with the fact that I found high blood pressure (high pressure is normal, low pressure is sometimes around 100) 3 years ago, and ultrasound found small kidney stones, can these factors indicate that the possibility of me suffering from polycystic kidney has increased greatly? Does blood pressure rise in polycystic kidney patients with only a few cysts in the early stage? Or does it mean that a patient with polycystic kidney will have elevated blood pressure only when the number of cysts is already large, so my current elevated blood pressure should be caused by something else, such as maybe just ordinary primary hypertension without any relation to polycystic kidney? Mao Zhiguo replied: The upload of the kidney MR film is too unclear to see the cysts in the kidney clearly, but according to your description the number of kidney cysts does not meet the criteria for diagnosing polycystic kidney disease. It is still necessary to make a more reliable judgment based on clear imaging data and the results of clinical urine and blood tests. If you have the conditions, you can go for mutation gene testing of polycystic kidney disease to further increase the certainty of diagnosis.
