RESUMO
BACKGROUND: Current prostate biopsy (PBx) protocol for prostate cancer (PCa) diagnosis is to perform systematic biopsies (SBx) combined with targeted biopsies (TBx) in case of positive MRI (i.e. PI-RADS ≥ 3). To assess the utility of performing SBx in combination with TBx, we determined the added value of SBx brought to the diagnosis of PCa according to their sextant location and MRI target characteristics. METHODS: In our local prospectively collected database, we conducted a single-center retrospective study including all patients with a suspicion of PCa, who underwent transrectal ultrasound-guided (TRUS) prostate biopsies (PBx) with a prior MRI and a single lesion classified as PI-RADS ≥ 3. We have characterized the SBx according to their location on MRI: same sextant (S-SBx), adjacent sextant (A-SBx), ipsilateral side (I-SBx) and contralateral side (C-SBx). The added value of SBx and TBx was defined as any upgrading to significant PCa (csPCa) (ISUP ≥2). RESULTS: 371 patients were included in the study. The added value of SBx was 10% overall. Regarding the lesion location and the SBx sextant, the added value of SBx was: 5.1% for S-SBx, 5.4% for A-SBx, 4.9% for I-SBx and 1.9% for C-SBx. The overall added value of SBx was 6.8% for PI-RADS 3 lesions, 14% for PI-RADS 4 lesions and 6.7% for PI-RADS 5 lesions (p = 0.063). The added value of SBx for contralateral side was 1.9% (2/103), 3.1% (5/163) and 0% (0/105) for PI-RADS 3, PI-RADS 4 and PI-RADS 5 lesions, respectively (p = 0,4). The added value of SBx was lower when the number of TBx was higher (OR 0.57; CI 95% 0.37-0.85; p = 0.007). CONCLUSIONS: Our results suggest that the utility of performing SBx in the contralateral lobe toward the MRI lesion was very low, supporting that they might be avoided.

AIM: To evaluate the results of GreenLight XPS photovaporization (PVP/XPS) with intraoperative transrectal ultrasonographic monitoring for the treatment of large Benign Prostatic Hyperplasia (BPH) (>80mL). PATIENTS AND METHODS: Operative and perioperative data of 82 patients were collected prospectively. Complications and functional outcomes (IPSS, quality of life (QoL) score, maximal flow rate and post-void residual (PVR)) were evaluated at 1, 3, 12 months post-operatively prostate volume and PSA were assessed at 3 and 12 months post-operatively. RESULTS: Median patient age was 68.5years (50-85). Twenty percent had an indwelling catheter and 5%/22% were on anticoagulant/antiplatelet therapy. Median prostate volume and PSA were 103mL (80-220) and 6.4ng/mL (0.66-44.0). Median operative time and energy delivered were 107min (46-219) and 581kJ (212-1193). Energy delivered/prostate volume was 5.4kJ/mL (1.6-10.5). Transurethral catheter was removed at day 1 or 2 in 96% of cases. Patients were discharged as outpatient, p.o. day 1 or day 2 in 4%, 55% and 21% of cases, respectively. Transfusion and Clavien≥3 complication rates were 1.2% and 3.7%. Significant improvement of IPSS (4 vs 19.5), QoL (1 vs 5), maximum flow rate (19.1 vs 8.2mL/s) and PVR (26 vs 100mL) was observed (P<0.001) at 12-months evaluation. PSA and prostate volume were decreased by 61 and 62%. Late complications were urethral strictures (6%), stress incontinence (1.2%). Eighty-five percent of patients had no antegrade ejaculation. CONCLUSION: The treatment of large BPH with PVP/XPS is safe and effective, with a long operative time. The functional outcomes are good and stable at mid-term evaluation. LEVEL OF EVIDENCE: 4.

OBJECTIVE: To compare the morbidity of limited pelvic lymphadenectomy to extended lymphadenectomy in patients undergoing LRP (Laparoscopic Radical Prostatectomy) for clinically localized prostate cancer. PATIENTS AND METHODS: We performed a prospective monocentric study focused on 303 consecutive patients having a pelvic lymphadenectomy during LRP from June 2000 to April 2010. One hundred and seventy six patients had a limited pelvic lymphadenectomy (June 2000-June 2006, group 1). One hundred and twenty seven patients had an extended pelvis lymphadenectomy (June 2006-April 2010, group 2) including two sub-groups according to the lateral limit of the procedure i.e. with (group 2a, 60 patients) or without dissection of the lateral side of the iliac artery (group 2b, 67 patients). RESULTS: Preoperative data (age, BMI, cTNM, Gleason score and PSA) were comparable between the groups. The number of lymph nodes and the incidence of metastatic lymph nodes were lower in group 1 (6,7 lymph nodes and 5,7%) compared to group 2 (a+b) (15.6 lymph nodes and 18.9%) (P=0.001 and P=0.0004). However, there was no difference between groups 2a and 2b (15.4 and 16.7% vs 15,8 and 20.8% P=0.65 respectively). There were more complications in the extended lymphadenectomy group compared to the limited procedure (35.4% vs 14.2%, P=0.0001), in particular more lymphatic complications (27.5% vs 10.2% P=0.0001) and lymphoedema (LO) (15.7% vs 0.6% P=0.00001). However the lymphorhea (LR) and lymphocele (LC) rate was not different (P=0.11 and P=0.17). All complications were mainly of low Clavien's classification grade (1+2) whatever the group of lymphadenectomy. The hospital stay was not increased in group 2a or 2b in regard to group 1. The rate of LR and LC was higher in group 2a than in group 1 (P=0.02 and P=0.05) but not between group 2b and 1 (P=0.81 and P=0.47). CONCLUSION: Our study showed a higher rate of complications after extended pelvic lymphadenectomy but of low grade in most cases. Moreover the lateral dissection sparing the lateral side of the iliac artery reduced the risk of lymphatic complications without decreasing the number of lymph nodes removed and the rate of metastasis.

PURPOSE: The main purpose of this study was to report urinary continence after laparoscopic radical prostatectomy (LRP) for localised prostate cancer and the return to baseline rate for urinary continence. The minor purpose was to determine the risk factors, which influence return to baseline urinary continence after radical prostatectomy. METHODS: Prospective evaluation of urinary continence with self-administered questionnaire in 300 consecutive LRP for localized prostate cancer. RESULTS: After LRP, at 3, 6 and 12 months, respectively 12.5%, 23% and 33.7% of patients recover baseline urinary continence. Fifty-four percent, 72.3% and 78.4% of patients did not wear pads 3, 6 and 12 months after LRP. In patients without pad, 43 % recovered baseline continence one year after radical prostatectomy. In univariate analysis, age older than 60 years (P=0.003, P=0.003, P=0.02, 3, 6 and 12 months after LRP) and no sparing of neurovascular bundles (P=0.01, P=0.08 at 3 and 6 months after LRP) were risks factors of urinary incontinence. In multivariate analysis, only age older than 60 years (P=0.018, P=0.01 and P=0.01 at 3, 6 and 12 months after LRP) was a risk factor of urinary incontinence. CONCLUSION: One year after LRP, 66.3% of patients had urinary incontinence according to our evaluation using stringent criteria, i.e. return to baseline continence status. However, only 21.6% of patients wore pads and less than 2% wore more than two pads per day.

We report a technical improvement of the Greenlight(®) XPS prostatectomy by using real time transrectal ultrasonography (TRUS) during the procedure. The TRUS probe lays on a flexible support fastened to the operative table. A wide screen with double display allows the surgeon to control the progress of the procedure with simultaneous ultrasonographic and endoscopic views. The depth of vaporization clearly appears as an hyperechogenic line together with an enlargement of the vaporization area. Real time TRUS monitoring during photovaporization of BPH decreases the learning curve, the risk of prostatic capsule perforation and bleeding, and allows to check the completeness of the procedure.

Development of face processing after unilateral brain lesions sustained before one year of age was assessed in children aged between seven and 10 years by various tasks involving face processing. Each child was paired with an age- and IQ-matched control. There were three unilateral right-hemisphere lesions and three unilateral left lesions. The results showed that some of the skills relative to face processing were preserved (or recovered?), whereas other skills were severely impaired; the pattern varied from one child to another. The existence of these dissociations shows that preservation of low-level visual processing together with exposure to the appropriate stimuli for several years is by no means sufficient for face processing skills to develop normally.
