In one, no gross stone was extracted during ERCP procedure, and no stone crystal was found in the aspirated bile under the microscopic exam.
In the remaining 14 (73.5%) stone was extracted using balloon or dormia basket following the dilatation of the papilla by 8-mm biliary balloons or up to 15-mm pyloric dilatation balloons for larger stones (figure 7).
The orifice was dilated using standard dilatation procedure under fluoroscopy and then CBD stones were extracted using stone extraction balloon and/or dormia basket.
Dimension stones are extracted in a highly selective manner, using time-consuming and expensive methods for freeing the blocks from the surrounding rock.
After 24 hours of immersion the stone sample was extracted from water, passed on humid filter paper in order to absorb excess water and weighed as indicated by the normative; the above described formula 1 for percentage absorption was applied thus allowing for each marble sample a comparison of the results obtained with the two different procedures for water absorption after a 24 hour immersion.
If the case is elderly and stones cannot be extracted, then plastic biliary stents can be introduced after biliary drainage.
Percutaneous nephrolithotomy or, rarely, anatrophic nephrolithotomy, is the treatment of choice for large or complicated stones (such as calyceal staghorn calculi) or stones that cannot be extracted using less invasive procedures.
The Voronoi shelf, with its tessellated patterns derived from the diagrams of the Russian mathematician George Voronoi, was extracted by stone saws from a five-and-a-half-ton block of veined white Carrara marble; the massive honeycomb structure has the incongruous delicacy of filigreed lace.
