6 cases of urethostenosis, 2 cases of urotithiasis and 1 case of urethral valves were cured one time. They were followed up from 10 months to 6 years and no dysuria occurred. 2 cases of external plank shedding after ureteropelvioplasty were treated with a placement of internal plank through the renal fistulization. The placement and evulsion of internal plank were carried out one time in 8 cases of ureteric calculi (the length of one calculi was as long as 4cm) and 12 cases of ureteropalsty. In 5 cases of upper remotion of internal plank, 4 cases were pulled out successfully and one failed to draw out. The effect is satisfactory to treat urological diseases by means of ureteroscopy in children.

The results show that: the tensile strength, flexural strength and flexural modulus increase by about 10.4%, 62.1% and 122.3% respectively when the mass fraction of the aluminum powder increases from 0 to 50%, while elongation at break and impact strength decrease by about 65.0 and 74.4% respectively; the tensile strength, elongation at break and impact strength all increase with decreasing the particle sizes of the aluminum powders.b Nylon-12 coated metal powders for the indirect SLS process were prepared by the dissolution precipitation process. The coated powders have only 1.0 wt% nylon-12, and their SLS green parts have sufficient strength for features as small as 1.0 mm to be built and post-processed and high dimensional accuracy. The green parts were subjected to the post processing processes including binder decomposition and infiltration of epoxy resin, and then the metal/polymer composite parts with relatively high strength and accuracy were formed.At present, micron-scale inorganic fillers have been widely used to reinforce nylon SLS parts.
