Stone fragmentation was performed using Swiss Lithoclast
Ultra (Boston Scientific, Natick, MA) and holmium laser were used to fragment stones during PCNL and URS, respectively.
Treatment of 150 ureteric calculi with the Lithoclast
Treatment of ureteric calculi use of Holmium: YAG laser lithotripsy versus pneumatic lithoclast
Clinical experience with a new ultrasonic and LithoClast
combination for percutaneous litholapaxy.
1998b, figs 2, 3) lack burrows, but are rich in allochthonous lithoclasts
and shells that were derived from shallower water.
5 mm large well-rounded lithoclasts
encrusted by Rothpletzella and Allonema.
5 cm) rounded lithoclasts
grades upwards into pure, well-sorted, fine-grained grainstone.
The reduced thickness of rocks, restricted number of ash layers, presence of oolites, discontinuity surfaces with lithoclasts
, and layered stromatolites indicate that the sequence is probably incomplete.
The rock contains pyritized skeletal particles of pelmatozoans, brachiopods, and trilobites, burrows of deposit feeders, and sporadically, pyritized lithoclasts
They contain probable Pennsylvanian-aged lithoclasts
(Alcock 1959), but no fossil evidence has been found for their age, so their assignment to the Triassic must be considered tentative.
The Karinu Member consists mainly of rough-bedded skeletal packstone with tempestite interlayers, pyritized lithoclasts
, rounded skeletons of stromatoporoids, and numerous pyritized discontinuity surfaces, indicating deposition in the inner part of the open shelf (IIIa) facies zone, from time to time influenced by storm waves and currents.
