Results With the new procedure, the tip of the prostate was peeled off completely without extra treatment, and this piece of the urethra,which was composed of surgical envelope, formed a vase-shaped natural surface to avoid urine irretention. The resected plane was covered by fibre and epithelium of surgical envelope,which could reduce irritation of urethra and bladder, and shorten hematuria and repair time. After enucleation of the enlarged prostate, the borderline became clear and blood supply was reduced, which facilitated the rapid resection without injury.
