Effect of intraprostatic epinephrine on intraoperative blood loss reduction during transurethral resection of the prostate.

Objective: To determine whether the use of intraprostatic epinephrine during transurethral resection of the prostate reduces intraoperative blood loss.

Methods: A random, double-blind, prospective study was carried out on twenty-three patients that underwent transurethral resection of the prostate. Patients were divided into two groups: (1) group receiving intraoperative intraprostatic injection of epinephrine (thirteen patients) and (2) group receiving intraoperative intraprostatic injection of saline solution as placebo (ten patients).

Nephron-sparing surgery for clear cell carcinoma in a solitary functional kidney. Case report and literature review.
