AB  - BACKGROUND: Although several distribution patterns of periprostatic neurovascular 
      bundles have been proposed, variant dissection technique based on these patterns 
      still confused surgeons. The aim of this study was to describe the periprostatic 
      neurovascular bundles and their relationship with the fascicles around prostate 
      and provide the accurate morphologic knowledge of periprostatic tissue for 
      prostate operation. METHODS: The pelvic viscera were obtained from 26 adult male 
      cadavers. They were embedded in celloidin and cut into successive slices. The 
      slices were explored with anatomic microscopy. 3-Dimensional reconstruction was 
      achieved with celloidin sections and series software. RESULTS: The prostatic 
      capsule which surrounded the dorsal, bilateral aspect of the prostate was 
      attached ventrally to anterior fibrous muscular stroma (AFMS). The lower part of 
      the striated sphincter completely embraced the urethral; the upper part of this 
      muscle covered the lower ventral surface of prostate. The upper ventral surface 
      of prostate is covered by the circular muscle of detrusor. The levator fascia and 
      the capsule adhered on the most convex region of the lateral prostate, but 
      separated on the other region. The pelvic neurovascular bundles (PNVB) divided 
      into the anterior and posterior divisions. The anterior division continued as 
      dorsal vascular complex (DVC). The distal part of DVC entered into penile hilum. 
      The posterior division continued as neurovascular bundles, and then as the 
      cavernous supply (CS). The distal part of CS joined into pudendal neurovascular 
      bundles. CONCLUSIONS: The capsule and AFMS formed a pocket like complex. There 
      were anterior and posterior neurovascular approaches from PNVB to penile hilum.
