What does fulguration mean?
Fulguration means two related things: the flashing of lightning, and — far more commonly today — a surgical technique in which abnormal tissue is destroyed by applying high-frequency electric sparks to its surface. Derived from the Latin fulgur, meaning lightning, the word entered English in the seventeenth century as a term for lightning's flash before physicians adopted it to describe electrical destruction of growths. In modern hospitals it appears most often in urology, where small bladder tumors are burned away with a spark-tipped electrode, and in procedures such as argon beam coagulation. The technique deliberately uses intermittent sparking rather than continuous contact, which limits heat damage to deeper layers. Though essentially confined to medical literature now, fulguration retains poetic appeal: few words so vividly capture the idea that a bolt of controlled lightning can heal as well as harm.
The flashing of lightning; the action or quality of flashing like lightning.
"The night sky was torn by a sudden fulguration over the ridge."
(Medicine) Destruction of tissue, especially tumors, by means of high-frequency electric sparks applied to the tissue surface without firm electrode contact.
"Small recurrent papillomas can be managed effectively by fulguration under local anesthesia."
This is the dominant modern sense, used almost entirely within medical and surgical writing.
The plural is rare and mainly found in medical texts referring to multiple fulguration procedures.
"The patient underwent three separate fulgurations over the course of treatment."
Before lasers and radiosurgery, surgeons fought tumors with controlled lightning — quite literally, sparks called fulguration.

Etymology of fulguration
Fulguration derives from the Latin fulguratio, from fulgurare ('to lighten, flash'), itself rooted in fulgur, meaning lightning. The word entered English in the early seventeenth century, first used to describe the flashing of lightning. It shares this root with fulminate (from fulmen, thunderbolt), which came to mean explosive detonation or angry denunciation, and with fulgent and refulgent, which describe shining brilliance. Medicine adopted the term in the nineteenth and twentieth centuries for electric spark-based destruction of tissue.

How fulguration is actually used
In contemporary usage, 'fulguration' is almost exclusively encountered in medical contexts, particularly surgery and urology; it is a formal technical term unfamiliar to most lay readers. The older sense relating to lightning is rare and largely historical or literary.
Easily confused with fulguration
Fulmination refers to violent explosion or loud, angry denunciation (from Latin fulmen, thunderbolt), whereas fulguration denotes lightning-like flashing or electric sparking to destroy tissue.
