Abstract
Purpose: We present the findings of 50 patients undergoing pure trans-umbilical laparo-endoscopic single-site surgery (LESS) living donor nephrectomy (LDN), between February 2010 and May 2014. Materials and Methods: Laparo-endoscopic single-site surgery LDN was performed through an umbilical incision. Different trocars were used, namely Gelpoint (Applied Mιdical, Rancho Santa Margarita, CA) SILS port (Covidien, Hamilton, Bermuda), R-port (Olympus Surgical, Orangeburg, NY) and standard trocars, inserted through the same skin incision but using separate fascial punctures. The standard laparoscopic technique was employed. The kidney was pre-entrapped in a retrieval bag and extracted trans-umbilically. Data were collected prospectively including questionnaires containing patient reported oral pain medication duration and time to recovery. Results: LESS LDN was successful in all patients. Mean warm ischemia time was 6.2 min (3–15), mean procedure time was 233.2 min (172–300), and hospitalization stay was 3.94 days (3–7) with a visual analogue pain score at discharge of 1.32 (0–3). No intraoperative complications occurred. The mean time of oral pain medication was 8.72 days (1–20) and final scar length was 4.06 cm (3–5). Each allograft was functional. Conclusion: Although challenging, trans-umbilical LESS LDN seems to be feasible and safe. Hence, LESS has the potential to improve cosmetic results and decrease morbidity.

[PMID: 25481672 DOI: 10.1016/j.purol.2014.10.002] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2014] [Revised: 09/25/2014] [Accepted: 10/06/2014] [Indexed: 11/25/2022]
Abstract
OBJECTIVES The main objective is the study of the evolution of the number of incident cases of prostate cancer in France from 2001 to 2012 from 5 hospital centers of urology. The secondary objective is to describe the characteristics of the incident cases and to compare them to those of the patients of the national registers of cancer for the period. MATERIAL AND METHODS Prospective observational multicentric study from 01/01/2001 to 31/12/2012 of databases in 5 French, public and private hospital centers of urology. The inclusive centers were selected outside departments with cancer register. The collected data were the prostatic biopsies performed in every center and the number of positive biopsies. The biopsies in cases of already known cancer and in re-evaluation were excluded. The data of age and stage (PSA and Gleason grade) were collected. The estimation of the incidence standardized in France is established after a period of observation of 3 years. The data updated in 2009 show a peak of incidence in 2005 then a decrease from 2006 (64,518 cases) until 2009 (53,465 cases). The median age in the diagnosis was of 70 years in 2005. RESULTS Overall, 18,392 prostatic biopsies were included in the analysis. The average rate of positive biopsies was stable over the period 51.41% (IQR 0,02). The total number of cases of positive biopsies increased from 2001 to 2007 (482 cases in 1028 cases) in 2007, then decreased from 2008 to 2012 (649 cases). There was no difference in this variation between the centers. The median age in the diagnosis was of 70 years (EIQ=1.5) in 2001 and 68 years (EIQ=2.75) in 2012. PSA at diagnosis was<10ng/mL in 65% of cases and 10 to 20ng/mL in 22% of cases in 2012. The population of patients of the study differed significantly from that of FRANCIM on the distribution by age ranges (year 2005, P<0.0001 and year 2009, P<0.001), which explains the gap of one year (on 2007 instead of 2006) of the peak of incidental cases. CONCLUSION The evolution of the number of incidental cases of prostate cancer in France from 2001 to 2012 from hospital data of 5 centers are similar to those of the network of registers representative of the French population. This observed evolution represents data available for cancer registers to estimate incidence variation between 2 publications. LEVEL OF EVIDENCE 4.

Abstract
PURPOSE To assess the factors influencing multiparametric (MP) magnetic resonance (MR) imaging accuracy in estimating prostate cancer histologic volume (Vh). MATERIALS AND METHODS A prospective database of 202 patients who underwent MP MR imaging before radical prostatectomy was retrospectively used. Institutional review board approval and informed consent were obtained. Two independent radiologists delineated areas suspicious for cancer on images (T2-weighted, diffusion-weighted, dynamic contrast material-enhanced [DCE] pulse sequences) and scored their degree of suspicion of malignancy by using a five-level Likert score. One pathologist delineated cancers on whole-mount prostatectomy sections and calculated their volume by using digitized planimetry. Volumes of MR true-positive lesions were measured on T2-weighted images (VT2), on ADC maps (VADC), and on DCE images [VDCE]). VT2, VADC, VDCE and the greatest volume determined on images from any of the individual MR pulse sequences (Vmax) were compared with Vh (Bland-Altman analysis). Factors influencing MP MR imaging accuracy, or A, calculated as A = Vmax/Vh, were evaluated using generalized linear mixed models. RESULTS For both readers, Vh was significantly underestimated with VT2 (P < .0001, both), VADC (P < .0001, both), and VDCE (P = .02 and P = .003, readers 1 and 2, respectively), but not with Vmax (P = .13 and P = .21, readers 1 and 2, respectively). Mean, 25th percentile, and 75th percentile, respectively, for Vmax accuracy were 0.92, 0.54, and 1.85 for reader 1 and 0.95, 0.57, and 1.77 for reader 2. At generalized linear mixed (multivariate) analysis, tumor Likert score (P < .0001), Gleason score (P = .009), and Vh (P < .0001) significantly influenced Vmax accuracy (both readers). This accuracy was good in tumors with a Gleason score of 7 or higher or a Likert score of 5, with a tendency toward underestimation of Vh; accuracy was poor in small (<0.5 cc) or low-grade (Gleason score ≤6) tumors, with a tendency toward overestimation of Vh. CONCLUSION Vh can be estimated by using Vmax in aggressive tumors or in tumors with high Likert scores.

Abstract
OBJECTIVE To compare complications after implantation of an artificial urinary sphincter (AUS) in patients with or without prior radiotherapy (RT). PATIENTS AND METHODS Between January 2000 and December 2011, 160 patients underwent AMS 800 AUS implantation in our institution. We excluded neurological and traumatic causes, implantation on ileal conduit diversion, penoscrotal urethral cuff position and those lost to follow-up. In all, 122 patients were included in the study, 61 with prior RT and 61 without prior RT. All patients underwent the same surgical technique by two different surgeons. All AUS were implanted with a bulbar urethral cuff position. The mean (range) follow-up was 37.25 (1-126) months. RESULTS In the patients without prior RT and those with prior RT, revision rates were 32.8% vs 29.5%, respectively (P = 0.59). The median time to first revision was 11.7 months. Early complications were similar in the two groups (4.9% vs 6.5%, P = 1). Erosion rates were not significantly different (4.9% vs 13.1%, P = 0.13). However, infection and explantation were more prevalent in patients with prior RT [two (3.2%) vs 10 (16.3%), P = 0.018 and three (4.9%) vs 12 (19.6%), P = 0.016, respectively]. Finally, continence rates were not significantly different [75.4% (without prior RT) vs 63.9% (with prior RT), P = 0.23]. CONCLUSION AUS is the 'gold standard' treatment of male urinary incontinence after re-education failure in patients with or without prior RT. Our experience showed similar functional outcomes in both groups but a higher rate of major complications in the group with prior RT.

Abstract
PURPOSE In the latest guidelines of the European Association of Urology, partial nephrectomy was a reference standard in tumors less than 7cm confined to the kidney. The invasion of the perirenal fat and therefore dissection in a potentially tumor tissue with an increased risk of recurrence. MATERIAL From 1995 to 2009, we retrospectively evaluated the oncological outcomes of partial versus radical nephrectomy in tumors with local extension beyond the boundaries of the kidney, without adrenal involvement or metastatic lymph node extension. We evaluated the histological factors influencing the prognostic. RESULTS A total of 43patients have been included (ten partial and 33radical nephrectomy). We did not found any significant difference in terms of specific and recurrence-free survival between partial and radical nephrectomy in tumor invading the perirenal fat (P=0.739 and P=0.683 respectively). Factors influencing the prognosis were the Fuhrman grade (P=0.010), the invasion of the urinary tract (P=0.017) and the presence of a positive surgical margin (P=0.041). The renal function was better after partial nephrectomy. The complication rate was similar between partial and radical nephrectomy. CONCLUSION The perirenal fat invasion by kidney tumor did not impact the oncological outcomes of partial versus radical nephrectomy with better functional outcomes for partial nephrectomy.

Abstract
Background: Owing to the scarcity of upper urinary tract urothelial carcinoma (UUT-UC) it is often necessary for investigators to pool data. A patient-specific survival nomogram based on such data is needed to predict cancer-specific survival (CSS) post nephroureterectomy (NU). Herein, we propose and validate a nomogram to predict CSS post NU. Patients and methods: Twenty-one French institutions contributed data on 1120 patients treated with NU for UUT-UC. A total of 667 had full data for nomogram development. Study population was divided into the nomogram development cohort (397) and external validation cohort (270). Cox proportional hazards regression models were used for univariate and multivariate analyses and to build a nomogram. A reduced model selection was performed using a backward step-down selection process, and Harrell's concordance index (c-index) was used for quantifying the nomogram accuracy. Internal validation was performed by bootstrapping and the reduced nomogram model was calibrated. Results: Of the 397 patients in the nomogram development cohort, 91 (22.9%) died during follow-up, of which 66 (72.5%) died as a consequence of UUT-UC. The actuarial CSS probability at 5 years was 0.76 (95% CI, 71.62-80.94). On multivariate analysis, T stage (P<0.0001), N status (P=0.014), grade (P=0.026), age (P=0.005) and location (P=0.022) were associated with CSS. The reduced nomogram model had an accuracy of 0.78. We propose a nomogram to predict 3 and 5-year CSS post NU for UUT-UC. Conclusion: We have devised and validated an accurate nomogram (78%), superior to any single clinical variable or current model, for predicting 5-year CSS post NU for UUT-UC.

Abstract
5094 Background: We analysed risk factors to predict oncologic outcomes at 5–11 year after laparoscopic renal cryoablation (LRC). Methods: Between 09/1997 and 010/2008, we performed renal cryoablation in 340 patients. Of these, 102 patients treated before 10/2003 (all laparoscopic) have minimum 5-year follow-up. Follow-up involved MRI imaging on postoperative day 1, 3 months, 6 months, 12 months, and then annually. Cryolesion biopsy was performed at 6-months. All data were prospectively accrued. Results: In the 102 patients with minimum 5-year follow-up, mean age was 66 years. Mean tumor size was 2.3 cm (0.9–5.0 cm). Median ASA score was 3 and mean BMI was 28. Six patients developed locoregional recurrence, 2 had locoregional recurrence with metastases, and 5 had distant metastases without locoregional recurrence. Overall, there were 7 cancer deaths. In the 69 patients with biopsy-proven renal cell cancer (median follow-up 81 mos; range 60–132 mos), 5-year overall, disease-specific, and disease- free survival was 75%, 92%, and 82%, respectively, while 10-year overall, disease-specific, and disease-free survival was 46%, 83%, and 79%, respectively. On multivariate analysis, previous radical nephrectomy for RCC was the only significant predictor for both recurrence- free survival and cancer-specific survival (p = 0.023 and 0.030, respectively). Relative risk of patients who has a history of radical nephrectomy for RCC treatment was 4.1 (95% CIs, 1.2 to 13.4), and 5.4 (95% CIs, 1.2 to 27.7) for disease-free survival and disease-specific survival, respectively. Conclusions: Laparoscopic renal cryoablation is effective oncologic treatment for renal mass in select patients. Disease-specific survival of 92% at 5-years and 83% at 10-years is possible. Preceding radical nephrectomy for RCC treatment was the only independent predicting factor for both disease-free and disease-specific survival.
