A former urologist, Dr. Saeid Shamsian practiced in the New York City area for over two decades. He treated cancers of the urinary system as well as benign conditions affecting the urinary tract and kidneys. Dr. Saeid Shamsian is the author of authoritative papers on urological and coronary health, addressing such subjects as primary testicular lymphoma and the urological complications that can result from coronary artery bypass surgery.

Also referred to as coronary artery bypass graft (CABG), such a surgery alleviates the symptoms associated with coronary artery disease or CAD. This condition causes the arteries that deliver oxygen and blood to the heart to constrict and harden over time. In some instances, urological issues may develop following the procedure. Complications may include acute urinary retention, urinary tract infection (UTI), or acute renal insufficiency (ARI).

In patients who exhibit ARI, the kidneys lose their ability to filter waste. This event may occur because of an adverse reaction to certain drugs or due to inadequate bloodflow. Treatment for the condition may include tracking sodium levels in the system, blood transfusions, lowering electrolyte levels, or dialysis.
