Blood loss during laparoscopic radical prostatectomy.

Purpose: To determine the impact of a variety of intraoperative parameters that may affect blood loss during laparoscopic radical prostatectomy (LRP).

Patients And Methods: Intraoperative blood loss was calculated for 757 consecutive LRPs performed by the same surgeon (CE) over a 6-year period. The impact of a number of intraoperative factors that may affect blood loss was studied.

Parameters of perineural invasion in radical prostatectomy specimens lack prognostic significance.

The prognostic significance of perineural invasion by prostate cancer is debated. We have evaluated the association between biochemical failure and measurements of perineural invasion in radical prostatectomy specimens. Perineural invasion was identified in sections using S-100 protein immunostaining.
