Gender: Female. Age: 74. Results of ultrasound of liver and gallbladder happened to incidentally noted bilateral simple renal cysts. Cysts in both kidneys. Largest on the right measuring 4.2 x 6.1 x 3.8 cm in the interpolar region. On the left, largest lies in the lower pole measuring 1.5 x 1.6 x 1.3 cm.
Urine test results: Protein is 1+, Glucose is 2+, WBC in urine is 32, RBC in urine is 0, EC in urine is 0, crystals is not seen, casts is not seen, other formed element is seen, micro organism is 2+. In 2002, CT scan shows a small cyst in the lower pole of the left kidney and measurement was not given in the report. In the expected course of the lower right ureter, in the pelvis below the level of the pelvic brim, there is a 3mm dense opacity of calcific density seen which could be a small ureteric calculus.
Appreciate if you could advise what is the best action required to take. Does the above findings implies that medical attention is required for that large cyst or it is very common to have such large size cysts in kidneys. Is it benign or maligant? Need to remove the cysts? Thank you very much.
