Abstract
The Thulium fiber laser has recently been tested as a potential alternative to the Holmium:YAG laser for lithotripsy. This study explores use of a short taper for expanding the Thulium fiber laser beam at the distal tip of a small-core fiber.

This study explores use of a short taper for expanding the Thulium fiber laser beam at the distal tip of a small-core fiber.</AbstractText><AbstractText Label="METHODS" NlmCategory="METHODS">Thulium fiber laser radiation with a wavelength of 1,908 nm, 10 Hz pulse rate, 70 mJ pulse energy, and 1-millisecond pulse duration was delivered through a 2-m-length fiber with 150-microm-core-input-end, 300-microm-core-output-end, and 5-mm-length taper, in contact with human uric acid (UA) and calcium oxalate monohydrate (COM) stones, ex vivo (n = 10 each). Stone mass loss, stone crater depths, fiber transmission losses, fiber burn-back, irrigation rates, and deflection through a flexible ureteroscope were measured for the tapered fiber and compared with conventional fibers.</AbstractText><AbstractText Label="RESULTS" NlmCategory="RESULTS">After delivery of 1,800 pulses through the tapered fiber, mass loss measured 12.7+/-2.6 mg for UA and 7.2+/-0.8 mg COM stones, comparable to conventional 100-microm-core fibers (12.6+/-2.5 mg for UA and 6.8+/-1.7 mg for COM stones). No transmission losses or burn-back occurred for the tapered fiber after 36,000 pulses, while a conventional 150-microm fiber experienced significant tip degradation after only 1,800 pulses. High irrigation rates were measured with the tapered fiber inserted through the working port of a flexible ureteroscope without hindering its deflection, mimicking that of a conventional 150 microm fiber.</AbstractText><AbstractText Label="CONCLUSIONS" NlmCategory="CONCLUSIONS">The short tapered distal fiber tip allows expansion of the laser beam, resulting in decreased fiber tip damage compared to conventional small-core fibers, without compromising fiber bending, stone vaporization efficiency, or irrigation rates.</AbstractText></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Blackmon</LastName><ForeName>Richard L</ForeName><Initials>RL</Initials><AffiliationInfo><Affiliation>Department of Physics and Optical Science, University of North Carolina at Charlotte, Charlotte, North Carolina 28223-0001, USA.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Irby</LastName><ForeName>Pierce B</ForeName><Initials>PB</Initials></Author><Author ValidYN="Y"><LastName>Fried</LastName><ForeName>Nathaniel M</ForeName><Initials>NM</Initials></Author></AuthorList><Language>eng</Language><PublicationTypeList><PublicationType UI="D016428">Journal Article</PublicationType><PublicationType UI="D013485">Research Support, Non-U.S. Gov't</PublicationType></PublicationTypeList></Article><MedlineJournalInfo><Country>United States</Country><MedlineTA>Lasers Surg Med</MedlineTA><NlmUniqueID>8007168</NlmUniqueID><ISSNLinking>0196-8092</ISSNLinking></MedlineJournalInfo><ChemicalList><Chemical><RegistryNumber>2612HC57YE</RegistryNumber><NameOfSubstance UI="D002129">Calcium Oxalate</NameOfSubstance></Chemical><Chemical><RegistryNumber>268B43MJ25</RegistryNumber><NameOfSubstance UI="D014527">Uric Acid</NameOfSubstance></Chemical><Chemical><RegistryNumber>8RKC5ATI4P</RegistryNumber><NameOfSubstance UI="D013932">Thulium</NameOfSubstance></Chemical></ChemicalList><CitationSubset>IM</CitationSubset><MeshHeadingList><MeshHeading><DescriptorName MajorTopicYN="N" UI="D002129">Calcium Oxalate</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000528">radiation effects</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D004867">Equipment Design</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D006801">Humans</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D017602">Lithotripsy, Laser</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000295">instrumentation</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="Y" UI="D055100">Optical Fibers</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D013932">Thulium</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000627">therapeutic use</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D046509">Tissue Culture Techniques</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D020709">Ureteroscopes</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D014527">Uric Acid</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000528">radiation effects</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D014545">Urinary Calculi</DescriptorName><QualifierName MajorTopicYN="N" UI="Q000473">pathology</QualifierName><QualifierName MajorTopicYN="Y" UI="Q000601">surgery</QualifierName></MeshHeading></MeshHeadingList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="entrez"><Year>2010</Year><Month>1</Month><Day>16</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="pubmed"><Year>2010</Year><Month>1</Month><Day>16</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2010</Year><Month>5</Month><Day>19</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="doi">10.1002/lsm.20883</ArticleId><ArticleId IdType="pubmed">20077487</ArticleId></ArticleIdList></PubmedData></pubmed></record>Pour manipuler ce document sous Unix (Dilib)
