Etymology: "Urinoma" is a medical term, a technical coinage built from two parts: "urine" and the suffix "-oma". The suffix comes from Greek "-ōma", a noun ending that in medicine denotes a swelling, mass or tumour, as in "carcinoma" or "lymphoma". Put together, the word names a collection of urine that has leaked out of the urinary tract and gathered in a sac-like pocket in the surrounding tissue. The suffix is misleading here, since a urinoma is not a tumour. The "-oma" ending was applied loosely to any abnormal mass or swelling, so a urine-filled collection took the same form as the growths it resembled. Doctors use it for a swelling caused by a leak, often after surgery or injury to the kidney, ureter or bladder.
