Surgeon must be aware of the following factors before taking on surgery in such compromised eyes: conjunctival scarring, low endothelial cell counts, poor pupillary dilatation, increased lens-iris diaphragm retropulsion, zonular weakness and pre-existing posterior capsular damage as well as diabetic retinopathy, low scleral rigidity, cystoid macular edema and other co-morbidities.
None of the cases were complicated by perforation of ureter, avulsion of ureter, or by stone retropulsion.
He explained that the equipment is 25 per cent faster than the conventional one, while it has shorter Lithotripsy time by 20 per cent, reduced stone retropulsion rate during Lithotripsy and can suction stone fragments at the same time.
(1,2) However, retropulsion of stone fragments are frequently seen during laser lithotripsy especially when using high energies for ureteral stones.
There was effacement of the right lateral recess and right neural foramen at the L3-L4 and effacement of the left lateral recess and left neural foramen at the L4-L5 due to tumor retropulsion (Figures 1-3).
The Ho:YAG laser can fragment all calculus compositions and produces less calculus migration (retropulsion) during treatment than the short-pulsed lasers [17-21].
Other frequent features include propulsion or retropulsion, festination, freezing of gait (FoG), and hesitancy of gait which may confer a "magnetic" character.
It plays a role in adduction, internal rotation, and retropulsion of the arm on the thorax, forming a single functional unit with the latissimus dorsi muscle.
Para el analisis estadistico, los items de la seccion motora de la UHDRS fueron agrupados en 10 dimensiones: 1) Alteraciones oculomotoras (seguimiento ocular, inicio de movimientos sacadicos, velocidad de las sacadas), 2) Disartria, 3) Protrusion Lingual, 4) Luria, 5) Bradicinesia (golpeteo de los dedos, pronosupinacion), 6) Rigidez, 7) Distonia, 8) Corea, 9) Alteraciones del equilibrio y 10) Retropulsion. Asimismo, los individuos fueron clasificados segun su estadio (inicial, intermedio, tardio) y segun su EI (juvenil, adulta, tardia).
