Laser lithotripsy (LL) has been evaluated against Extracorporeal Shock Wave lithotripsy (ESWL), finding both to be safe and effective. [3] [4] ESWL may be safer for small stones (<10 mm), but less effective for 10–20 mm stones. [3] A 2013 meta-analysis found LL can treat larger stones (> 2 cm) with good stone-free and complication rates. [5]
Lithotripsy is a procedure involving the physical destruction of hardened masses like kidney stones, [1] bezoars [2] or gallstones, which may be done non-invasively. The term is derived from the Greek words meaning "breaking (or pulverizing) stones" ( litho- + τρίψω [tripso]).
Some of the passed fragments of a 1-cm calcium oxalate stone that was smashed using lithotripsy. The most common use of extracorporeal shockwave therapy (ESWT) is for lithotripsy to treat kidney stones [3] (urinary calculosis) and biliary calculi (stones in the gallbladder or in the liver) using an acoustic pulse.
Stent placement can be useful for saving a kidney at risk for postrenal acute kidney failure due to the increased hydrostatic pressure, swelling and infection (pyelonephritis and pyonephrosis) caused by an obstructing stone. Ureteral stents vary in length from 24 to 30 cm (9.4 to 11.8 in) and most have a shape commonly referred to as a "double ...
Electrohydraulic Lithotripsy (EHL) is a medical procedure which uses targeted shockwaves to break up kidney stones and gallstones. [1] This form of extracorporeal lithotripsy is unique in that the shockwaves are produced by a vaporization bubble expanding and collapsing repeatedly, creating a pressure wave. [ 1 ]
Diagram of stent placement. In A, the catheter is inserted across the lesion. In B, the balloon is inflated, expanding the stent and compressing the plaque. In C, the catheter and deflated balloon have been removed. Before-and-after cross sections of the artery show the results of the stent placement. Arterial Stenting 3D Medical Animation
A ureteral stent (pronounced you-REE-ter-ul), or ureteric stent, is a thin tube inserted into the ureter to prevent or treat obstruction of the urine flow from the kidney. The length of the stents used in adult patients varies between 24 and 30 cm. Additionally, stents come in differing diameters or gauges, to fit different size ureters.
This is often utilized to break up calculi such as kidney stones and gallstones into pieces small enough to be passed from the body without undue difficulty, a procedure known as lithotripsy. The success of lithotripsy depends on the size and location of the stone, and the patient's age.
