To investigate the effectiveness of laparoscopic varicocelectomy (LV) in adolescents with varicocele and analyze the impact of internal spermatic artery (ISA) preservation on surgical outcomes.Data on 92 adolescents with left varicocele who underwent LV between December 1998 and January 2011 were retrospectively analyzed. The mean age of the patients was 13.2 ± 2.1 years. Age, grade of disease, number...
The stress-birefringence relationship was examined for amorphous poly(ethylene terephthalate) films under uniaxial stretching in the temperature range 80–95°C at various stretch speeds in order to study the effect of strain-induced crystallization. At high temperatures, the ordinary stress-optical rule (SOR) held well at low draw ratios; the birefringence was proportional to the stress. However, at...
