Free on board (FOB) is a contractual term that refers to the requirement that the seller deliver goods at the seller's cost via a specific route to a destination designated by the buyer. How It Works To understand how FOB terms work, let's look at an example.
A kidney cyst or renal cyst, is a fluid collection within the kidney. Most kidney cysts are âsimpleâ or âbenignâ meaning no treatment is required. Some cysts are more âcomplexâ and require either close radiographic imaging (with either a CT scan or MRI) or surgery since these cysts can be cancerous.
Signs and Symptoms. Kidney cysts usually do not cause any symptoms. Simple kidney cysts may cause complications like: 1  Abdominal or lumbar pain: due to the displacement of abdominal organs, rupture or bleeding of the renal cyst. 2  Hematuria: due to rupture of a renal cyst into the pyelocaliceal system.igns and Symptoms.
