Extracorporeal Shockwave Lithotripsy Eswl
Pain from procedure: Shock waves are typically applied through an interface brought into direct contact with the skin of the flank region on the side of interest. When shock waves are delivered, they can be quite uncomfortable. Anesthesia is needed to keep the patient comfortable, but also to help the patient stay still so that the shock waves can remain focused on the stone to maximize the chances of fragmenting it ...Read more
Vary...: Do you mean get over eswl-related discomfort or total post-eswl stone/fragment passage? For post-eswl discomfort, it may highly vary, days to weeks, depending on what you're and how your body/kidney responds to eswl. For stone/fragment passage, it may take 1 week to months, depending on the load ; density of stones and the eswl effectiveness to disintegrate them; it may take 1 week to months, or.. ...Read moreSee 1 more doctor answer
Is it better to have extracorporeal shock wave lithotripsy (eswl) or percutaneous nephrolithotomy (pcnl)?
Stone size determine: Shockwave lithotripsy minimally invasive, but not very effective for stones larger than 1 cm in diameter, and can not be used for branching "staghorn" stones. Can be used for larger stones if infectious in origin because they break up more easier. Percutaneous is more invasive, but usually a "one shot" procedure to clean out all the stone material.Swl requires minimal to no skill, pcnl needs skill. ...Read moreSee 1 more doctor answer
Kidney stones: Eswl uses high-energy shock waves produced by an electrical discharge, which are transmitted through water and directly focused onto a renal or ureteral stone with the aid of fluoroscopy. The change in tissue density between the soft tissues of the kidney and the hard stone results in a release of energy at the stone surface, which fragments the stone. The patient is sedated or anesthetized. ...Read more
Anesthesia is usual: During extracorporeal shock wave lithotripsy, most patients are under general anesthesia, or given intravenous analgesics by an anesthesiologist or nurse anesthetist. If the patient is not under general anesthesia (some systems don't require it) they may feel a "slap" in the area of the shock wave, but it is generally reduced by analgesics, and some drugs eliminate recall of the event.

Same but more: Extracorporeal shock wave lithotripsy (eswl) is used to break up stones which are stuck somewhere, whether it be the kidney or the bile duct or elsewhere. Risks include bleeding, damage to the surrounding tissue/organ, and when coupled with other procedures, generally mean a more difficult procedure. ...Read more
