Balloon Dilation Treatment of Phimosis in Boys (1200 words) |
 | The balloon dilation technique for treating phimosis in boys includes a balloon catheter, an inflator, a valve clip and two curved retractors, which are all made of disposable plastics. |
| Balloon dilation treatment is indicated for boy patients with a constricted preputial orifice impeding retraction of the prepuce over the glans penis and/or a history of either urinary tract infection, frequent micturition or bradyuria due to phimosis before the age of three years. |
| Dilation of the prepuce should be terminated if the balloon waist disappears or when the balloon diameter is 3-5mm greater than that of glans penis. |
| Dilation (9480 words) |
| Dilational lineaments are part of a larger array of Europan lineae which crisscross the satellite, discovered by the Voyager spacecraft (Smith et al., 1979; Lucchitta and Soderblom, 1982), and viewed at higher resolution by the Galileo spacecraft (Belton et al., 1996; Greeley et al., 1998; Greenberg et al., 1998a). |
| Dilation may accompany ridge formation when ice or slush accumulates in the cracks, forcing the opposing blocks apart when daily compressive tidal stress is applied, according to Greenberg et al. |
| Because external pulling counteracts tidal compression, the relative importance of the two end-member processes determines the morphology of Europan dilational lineaments, by controlling the degree of elevation, and the prominence of a central groove and of bilateral symmetry. |
