Objective: To analyze the correlation between pathological data found in radical prostatectomy and previously performed biopsy in patients at low risk prostate cancer., Material and Methods: A descriptive, cross-sectional study was conducted to assess the characteristics of radical prostatectomies performed in our center from January 2012 to November 2014. The inclusion criteria were patients with low-risk disease (cT1c-T2a, PSA≤10ng/mL and Gleason score≤6). We excluded patients who had fewer than 8 cores in the biopsy, an unspecified number of affected cores, rectal examinations not reported in the medical history or biopsies performed in another center., Results: Of the 184 patients who underwent prostatectomy during this period, 87 met the inclusion criteria, and 26 of these had<3 affected cores and PSA density≤.15 (very low risk). In the entire sample, the percentage of undergrading (Gleason score≥7) and extracapsular invasion (pT3) was 18.4% (95% CI 10.3-27.6) and 10.35% (95% CI 4.6-17.2), respectively. The percentage of positive margins was 21.8% (95% CI 12.6-29.9). In the very low-risk group, we found no cases of extracapsular invasion and only 1 case of undergrading (Gleason 7 [3+4]), representing 3.8% of the total (95% CI 0-12.5). Predictors of no correlation (stage≥pT3a or undergrading) were the initial risk group, volume, PSA density and affected cores., Conclusions: Prostate volume, PSA density, the number of affected cores and the patient's initial risk group influence the poor pathological prognosis in the radical prostatectomy specimen (extracapsular invasion and Gleason score≥7)., (Copyright © 2014 AEU.

Since 2007, various urological procedures have been performed with laparoendoscopic single-site surgery (LESS surgery), including nephrectomy, pyeloplasty, simple prostatectomy and, with the refinement of laparoscopic instrumentation, radical prostatectomy. This paper reports our initial experience in radical prostatectomy using the SILS Port from Covidiem and two lateral 5-mm trocars for triangulation. The SILS Port allows for accurate, simple insertion through a Hadson incision. The flexible port accommodates three 5-mm cannulas or two 5-mm cannulas and a 12-mm port for easier instrument exchange through a single incision. This approach decreases morbidity from bleeding, hernia and/or internal organ damage and improves cosmetic. One-port single-incision laparoscopy is part of the natural development of minimally invasive surgery. Future research is required to assess the intraoperative and postoperative benefits of LESS surgery as compared to standard laparoscopy.
