VETERINARY STONE TREATMENT DOGS CATS BY LASER
UROLIFEINDIA.COM: For female dogs and cats, an appropriate size of rigid cystoscope is utilized. There are advantages to having both a 30° telescope and 0° telescope available. The 0° telescopes are useful as an operating scope because they allow direct visualization in front of the scope tip during stone fragmentation. However, the 30° telescopes are superior for diagnostic evaluation prior to and after laser lithotripsy. We generally use the following scope for various size patients.
Female cats: 1.9 mm with 9 Fr sheath
Small to medium sized female dogs: 2.7 mm with 14.5 Fr sheath
Large female dogs (> 20 kg): 4.0 mm with 19 Fr sheath
Urethral mucosal edema causes a narrowing of the urethral lumen. If mucosal edema occurs, a smaller scope may be required for re-entry into the urinary bladder in some cases. This is an even more profound problem in male dogs and may limit which patients are considered large enough for a transurethral approach.
For male dogs, we utilize a flexible ureteroscope (7.5 Fr diameter x 70 cm length) as cystoscope. Not all male dogs are acceptable candidates for laser lithotripsy. Factors affecting patient selection for the procedure include urethral diameter (minimum body weight 3-4 kg), relative stone burden and whether or not a ureteral access sheath can be placed transurethrally. There are a few special precautions in performing laser lithotripsy in male dogs. Do not pass fiber with scope tip deflected because the tip of the laser fiber can damage lining of the working channel. We attempt to use a laser catheter whenever possible to minimize the risk of injury to the working channel. Similar to female patients, one should keep the fiber clatting and laser tip visible prior to activation of the laser. You must also keep track of volume infused (<10 ml/kg) to avoid overdistention or rupture of the urinary bladder.FOR MORE INFORMATION CALL : 9810019324 VISIT : http://ping.fm/iYCgo
