Prospective evaluation of ambulatory laser vaporization of the prostate for benign prostatic hyperplasia.

Background And Objective: Photoselective vaporization of the prostate (PVP) is an alternative to transurethral resection of the prostate in the surgical treatment of benign prostatic hyperplasia (BPH). Our objective was to prospectively evaluate the feasibility, safety, and efficacy of ambulatory photoselective vaporization of the prostate for benign prostatic hyperplasia.

Materials And Methods: We prospectively collected data of all consecutive patients who underwent ambulatory PVP with the Greenlight(®) laser 180-W XPS at two centers between May 2012 and June 2013.

Nephron-sparing surgery is superior to radical nephrectomy in preserving renal function benefit even when expanding indications beyond the traditional 4-cm cutoff.

Objectives: To analyze to what extent partial nephrectomy (PN) is superior to radical nephrectomy (RN) in preserving renal function outcome in relation to tumor size indication.

Methods And Materials: Clinical data from 973 patients operated at 9 academic institutions were retrospectively analyzed. Glomerular filtration rate (GFR) before and after surgery was calculated with the abbreviated Modification of the Diet in Renal Disease equation.

Are warm ischemia and ischemia time still predictive factors of poor renal function after partial nephrectomy in the setting of elective indication?

Purpose: To evaluate renal function and to identify factors associated with renal dysfunction in the elective indications setting of nephron-sparing surgery (NSS).

Methods: We retrospectively reviewed operative data and glomerular filtration rate (GFR) of 519 patients treated by NSS in an elective indications setting between 1984 and 2006 in eight academic institutions. A GFR decrease under the thresholds of 60 or 45 ml/min at last follow-up was considered a significant renal dysfunction.
