Philippine Man Has Kidney Milk of Calcium Cyst & Family Asks If Harmful

“Hello! Doc, busy? My husband Doc. on this coming tuesday he has a check up again. Can I send you a result of his ultra sound? He feel that he has a frostate enlargement but I said to him you need to go to the doctor to make medical check up, then he noticed that he has a milk calcium syst in the left kedney!” (Ms.DD, Philippines)

Hello Ms. DD,

Thank you for sending your husband’s kidney sonographic report on Facebook.  After viewing the ultrasound report, the radiologist documented “the kidneys are normal in size,” and the “rest of the bilateral renal parenchyma are homogenous.”  Put simply, your forty-seven year old husband, Pepe, has functioning, normal kidneys.   However, “a 1.3 cm cortical cyst with milk of calcium is seen in the left kidney” was also reported by his physician. 

Similar to kidney stones, milk of calcium cysts are composed of precipitated, calcium salts (oxalate, calcium, and phosphate).  These cysts form due to stasis of urine in urinary tract cavities with suboptimal drainage.  You mentioning that “He feel that he has a frostate enlargement” is a potential cause of decreased urine flow; however, kidney stones have serious symptoms not limited to blood in the urine, nausea, vomiting, pain on urination, urinating small amounts of urine, fever, chills, and pain that spreads to the groin.   When I asked you if your husband had any symptoms, you said no major complaints. 

Thus, the renal milk of calcium cyst appears to be an incidental finding on your husband’s ultrasound exam, and to answer your question “You know what is the milk calcium syst? In left kedney? It is need a surgery doc?” my reply is no surgery is needed. 

I am deeply humbled that you contacted me, and I value your trust in my opinion.  Thus, since your husband “feel he has frostate enlargement,” I suggest that your husband ask his doctor to perform a digital rectal exam and run a PSA test (prostate specific antigen) test.  The PSA test results provide a snap shot of potential prostate conditions including benign prostatic hypertrophy, and along with a digital rectal exam, this test will help rule out prostate cancer.  We should make sure that the prostate is not evolving into a future, serious problem.  Thank you for your question and faith in me.  God Bless you, God Bless Pepe, and God Bless the Philippines.

Respectfully,

Dr. Roshin
