Since I was under an anesthetic, I didn't hear or see any of the operation -- let alone a "KABOOM". Over twelve hours later, the kidney stone appears to be gone. Although there continued to be some kidney pain early in the day, this evening it is more of a minor discomfort.
A week from now, there will be an x-ray to see what remains -- if anything -- after the stone was blasted.
According to WebMD, this quote from the article Extracorporeal Shock Wave Lithotripsy describes the process.
You lie on a water-filled cushion, and the surgeon uses X-rays or ultrasound tests to precisely locate the stone. High-energy sound waves pass through your body without injuring it and break the stone into small pieces. These small pieces move through the urinary tract and out of the body more easily than a large stone.As I was being transferred to the operating table, I asked the technician how it ever was found to blast the stones in this fashion. He started to explain about airplane cock pit windows being pitted after driving through a rainstorm. The sedative must have been going into my bloodstream because that was all I heard. I really wonder what was the connection from pitted windows to ESWL. I found nothing when I searched the internet for anything about how the technology came about.
What I did find is that the ESWL procedure does have some risks -- in 5%-20% of the procedures performed. That would be another health risk along with my elevated cholesterol -- for which I take no statins. Actually, I take no drugs. That does seem to surprise the medical community that a 73 year old person can be healthy without taking any drugs.
This past week proved to be another "pot hole in the road of life". Soon I will be back to the every other day hiking habit.
