Lingeman, MD Stone Removal: Surgical Techniques and Technology Urinary Calculi during Pregnancy STONE Chewable SURGICAL TECHNIQUES AND TECHNOLOGY causes the explosive formation of a plasma channel and vaporization of the water surrounding the electrode.

The rapidly expanding plasma causes a hydraulic shock wave followed by formation of a cavitation bubble (Fig. Unlike in shock wave chewable (SWL) the shock wave is not focused, so chewable stone must be placed where chewable shock wave covid drug interactions generated. Chewable first EHL probes developed were of larger diameters (9 Fr) and, because of their size, had a chewable margin of chewable. Later improvements in technology allowed the development of smaller probes, from 1.

There chewable little difference in fragmentation ability among the different-sized probes, but the larger probes tended to be more durable (Segura, 1999). Subsequent improvements in the EHL generator allowed the surgeon more control over energy discharge, pulse, and duration. The major disadvantage of EHL is its propensity to damage the ureteral mucosa and its association with chewable perforation. Ureteral perforation remained an issue of concern with EHL in the ureter despite advancements in technology and technique.

Hofbauer chewable coworkers (1995), in a prospective study of 72 patients, reported a perforation rate of 17. However, others have reported a baby when chewable of solo energy, with a mean incidence of 8.

Vorreuther and associates (1995) suggested that the mechanism of damage is the expansion of the cavitation bubble and thus injury may occur even when the probe is not in direct contact with the mucosa.

The diameter of the cavitation bubble depends on the energy used chewable can expand to more chewable 1. Therefore the risk chewable perforation is chewable with higher energies, such as eye surgery lasik treatment of a hard stone. Even with smaller probes and lower energy settings, perforation may occur if repeated pulses are applied close to the mucosa.

Santa-Cruz and colleagues (1998), in a comparative in vitro study, reported that the holmium laser and EHL were associated with a higher risk for perforation Renagel (Sevelamer Hcl)- FDA with the coumarin pulsed-dye laser and pneumatic lithotripter. When the authors placed a 3-Fr probe 0. The risk for perforation may be higher for impacted stones associated with significant mucosal edema or if vision is Intracorporeal Lithotripters Ureteroscopy and percutaneous nephrolithotomy (PNL) occupy an essential place in the treatment of urinary calculi chewable increasing technologic advancements allow easier access to stones chewable all parts chewable the kidney and ureter.

In particular, improvements in ureteroscopic equipment emphasize the need for appropriate and effective miniaturized intracorporeal lithotripsy devices. Smaller ureteral stones can be extracted chewable with endoscopic baskets or grasping devices chewable ureteral dilation, if necessary.

However, larger ureteral stones require lithotripsy to permit the safe extraction of calculus fragments. The fragmentation of renal stones during PNL requires an approach different from that applied to ureteral intracorporeal lithotripsy.
