Surgical approach to vesicourethral anastomotic stricture following radical prostatectomy.

Introduction: Vesicourethral anastomotic stricture following prostatectomy is uncommon but represents a challenge for reconstructive surgery and has a significant impact on quality of life. The aim of this study was to relate our experience in managing vesicourethral anastomotic strictures and present the treatment algorithm used in our institution.

Patients And Methods: We performed a descriptive, retrospective study in which we assessed the medical records of 45 patients with a diagnosis of vesicourethral anastomotic stricture following radical prostatectomy.

[Comparison of the Biochemical Recurrence risk between Radical Prostatectomy and Brachytherapy in the treatment of low- and intermediate-risk prostate cancer].

Objectives: To evaluate the results of patients treated with Radical Prostatectomy (RP) and Brachytherapy for low- and intermediate-risk localized prostate cancer and to determine the Biochemical Recurrence (BCR) risk according to the treatment performed.

Methods: The study included 129 patients treated with iodine-125 seeds Brachytherapy, 98 patients treated with Laparoscopic RP (LRP), and 61 patients treated with Robotic RP (RRP) at our institution between December 1999 and January 2010, who had a low-risk disease according to D'Amico criteria (PSA <10 ng/mL, Gleason < or = 6, cT1c-T2a), or an intermediate-risk disease (PSA = or >10 and < 20 ng/mL, Gleason = 7, cT2b), but with a tumor burden of up to 30%. Follow-up was conducted with PSA at 1, 3, and 6 months, and then every six months.

Salvage radical prostatectomy after radiotherapy.

Objectives: To determine the oncological and functional results obtained after salvage radical prostatectomy (SRP) in patients with recurrence following radiotherapy (3 consecutive PSA rises after a nadir until the year 2006, then 2 ng/mL above nadir ) for prostate cancer (PC), and to analyze the impact of different pre-and postoperative variables on biochemical recurrence-free survival (BCR-free survival).

Methods: Retrospective analysis of 29 cases treated with SRP, 23 cases of conventional technique and 6 cases assisted by the Da Vinci surgical system between August 2004 and March 2012 at the Hospital Italiano de Buenos Aires. There was an attempt to preserve neurovascular bundles in cT1c patients with low tumor volume, Gleason score 7 or less, and favorable surgical anatomy.

Incidence of positive surgical margins after robotic assisted radical prostatectomy: Does the surgeon's experience have an influence on all pathological stages?

Objective: The aim of this study is to analyze the clinical and surgical features of patients who underwent robotic-assisted radical prostatectomy (RARP) at our institution, and the impact of the surgeon's experience in the oncological results related to pathological stage.

Material And Methods: An analysis of 300 RARP consecutively performed by the same urologist was conducted. Patients were divided into 3 groups of 100 patients in chronological order, according to surgery date.

Histologic changes after urethroplasty using small intestinal submucosa unseeded with cells in rabbits with injured urethra.

Objective: To determine whether small intestine submucosa has the same regenerative capacity when urethroplasty is performed in injured urethras.

Methods: Our experiment was conducted in 30 New Zealand male rabbits, all of which had urethral injury. One month after the injury, the animals were randomized into a control group or a group with onlay urethroplasty with small intestine submucosa.
