What is holmium laser lithotripsy?
Holmium laser lithotripsy uses lasers to break stones that are located in the urinary tract. This could include stones in the bladder, kidneys, ureters (tubes that carry urine from the kidneys to the bladder) or urethra (the tube through which urine leaves the body from the bladder). A flexible laser fiber is inserted through a scope (camera) placed in the urinary tract via the urethra to break up the stones. The stone fragments are then removed with a small basket or other instruments. The procedure is done without any incisions (cuts).
Why is holmium laser lithotripsy done?
It's an alternative to a procedure called extracorporeal shockwave lithotripsy. In that procedure, sound waves from outside the body are used to break up the stones. Holmium laser lithotripsy has been shown to be effective no matter the size, location and/or hardness of stone. These factors limit the shockwave lithotripsy's effectiveness.
What should I do to prepare for holmium laser lithotripsy?
Check with your doctor to see if there are any medications you should avoid prior to the procedure. You will likely be asked to not eat or drink anything after midnight prior to the procedure.
What should I expect after holmium laser lithotripsy?
You may have some blood in your urine or discomfort with urination depending on where your stones were. If a stent is placed, this can cause some irritation of the bladder. You may also have nausea and fatigue after having anesthesia. Follow all recommendations that your doctor provides in your discharge instructions.
