Urine colour after radical prostatectomy predicts urinary leakage at the vesicourethral anastomosis.

Objective: The aim of this investigation was to determine whether postoperative urine colour could be used as a predictor for the presence or absence of a urinary leakage at the vesicourethral anastomosis after open radical prostatectomy.

Material And Methods: In this prospective study, the urine colour of 223 patients who underwent open radical prostatectomy due to histologically proven localized prostate cancer was assessed macroscopically and microscopically on postoperative day (POD) 6, 7 and 8. All patients underwent evaluation of perianastomotic extravasation by retrograde cystography on POD 8.

The impact of bladder neck mucosal eversion during open radical prostatectomy on bladder neck stricture and urinary extravasation.

Purpose: To determine whether the bladder neck mucosal eversion (BNM-eversion) during radical retropubic prostatectomy (RRP) reduces the risk of bladder neck stricture (BNS) and of peri-anastomotic extravasation (PAE) in postoperative cystography.

Methods: Two hundred and eleven patients with clinically localized prostate cancer underwent RRP and were prospectively randomized into patients with BNM-eversion (group I) and without BNM-eversion (group II). All patients underwent an evaluation of PAE by retrograde cystography on postoperative day 8.

Prolonged cold ischemia time for laparoscopic partial nephrectomy with a new cooling material: Freka-Gelice--a comparison of four cooling methods.

Background And Purpose: It is well known that hypothermia protects renal tissue from ischemic damage. So far, no standardized cooling method for laparoscopic surgery has been established. The traditionally used cooling method during open partial nephrectomy (OPN) is crushed ice applied around the kidney; for laparoscopic use, transarterial and transureteral perfusion cooling are described.

Detection of urinary leakage after radical retropubic prostatectomy by contrast enhanced ultrasound - do we still need conventional retrograde cystography?

Introduction: To prospectively evaluate the accuracy of transvesical contrast-enhanced ultrasound (CEUS) as an alternative method for the detection of anastomotic leakage after radical retropubic prostatectomy (RRP) in comparison with the current standard method of conventional retrograde cystography (CG).

Patients And Methods: Forty-three patients underwent RRP for histologically proven localized prostate cancer. The vesico-urethral anastomosis was evaluated 8 days after RRP by CG and CEUS.

Comprehensive MR evaluation of renal disease: added clinical value of quantified renal perfusion values over single MR angiography.

Purpose: To evaluate the diagnostic accuracy of quantified renal perfusion parameters in identifying and differentiating renovascular from renal parenchymal disease.

Materials And Methods: In all, 27 patients underwent renal perfusion measurements on a 3.0 T magnetic resonance imaging (MRI) system.
