Histomorphologically, the human BPH tissues showed hyperplasia of epithelial and stromal tissues, which were characterized by hyperplasia nodules, high cylindrical epithelial cells, irregular and dilation of acini with villous projections, back-to-back interacinar space, and ischesis
(Figure 1A) .
Complex stenosis cannot be effectively resolved by using a high frequency electric knife or balloon dilatation, and eventually progresses to refractory airway stenosis, which is often treated by silicone stent implantation.[sup], However, stent implantation can result in complications such as stent migration, hyperplasia of granulation tissue, formation of ulcerative tissue around the stent, and ischesis
in the stent,[sup] which can sometimes require emergency interventional bronchoscopic therapy.
