Ye sthank you- What is the following- Left kidney shows atypical cortical cystic lesions in the lower pole 2.6cm with peripheral calcification and adjacent 2.6cm  and There is dilatation of the left pelvocalicceal structure secondary to 1.2 cm calculus lodged in the renal pelvis
Good Day, and thank you for being with Chat Doctor ! I can see two separate kidney problems and ill discuss each separately. First your left kidney is obstructed and not functioning properly due to a kidney stone that is blocking the way. Treatment for this would be ESL (shockwave therapy) to fragment the stone and remove the obstruction. This is a more urgent problem, and you should consult your local Urologist so that there will be less kidney damage due to obstruction/blockage. The second kidney problem is the cortical cyst. Since your cysts shows atypical features with peripheral calcifications then you need a ct scan with IV contrast to grade your cortical cyst properly to determine the risk for malignancy or kidney cancer. I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications at: http://www.ChatDoctor .com/doctors/ Chat Doctor.  Best wishes.
