Purpose: To evaluate renal function and to identify factors associated with renal dysfunction in the elective indications setting of nephron-sparing surgery (NSS).
Methods: We retrospectively reviewed operative data and glomerular filtration rate (GFR) of 519 patients treated by NSS in an elective indications setting between 1984 and 2006 in eight academic institutions. A GFR decrease under the thresholds of 60 or 45 ml/min at last follow-up was considered a significant renal dysfunction.
Unlabelled: What's known on the subject? and What does the study add? Upper urinary tract urothelial carcinomas (UUT-UCs) are rare tumours. Because of the aggressive pattern of UC, radical nephroureterectomy (RNU) with bladder cuff removal remains the 'gold-standard' treatment. However, conservative strategies, such as segmental ureterectomy (SU) or endourological management, have also been developed in patients with imperative indications.

Methods: The data from 888 patients who had been operated upon at eight french university hospitals were retrospectively analyzed. Glomerular filtration rate (GFR) pre- and post-surgery was calculated with the abbreviated Modification of Diet in Renal Disease (MDRD) equation.
Background: The purpose of this study was to compare the postsurgical survival of UUT-UC patients treated with ONU and LNU.
Methods: Using a multi-institutional, national, retrospective database, we identified patients with UUT-UC who underwent radical nephroureterectomy by open access (ONU) or by the minimally invasive alternative (LNU). Survival curves were estimated using Kaplan-Meier method.
Introduction: Evaluation of the effectiveness and tolerance of thermoformable metallic spiral stents Memokath(®) 051 (Bard, Pnn Medical) in the treatment of localized ureteral stenosis in non-operable patients who have JJ ureteral stents.
Material And Method: Prospective, descriptive and multicenter study of patients with ureteral strictures treated with metallic ureteral stents Memokath(®) 051. Assessment criteria (recurrent stenotic, permeability, tolerance) were measured by clinical, biological and radiological examination at 1 month, and then every 3 months.
Background: The advanced renal cell carcinoma (RCC) affects patients mainly ∼60 years of age and who may have an active sex life. The objective of the study was to investigate possible sexual disorders in a male population with advanced RCC treated with a molecular targeted therapy (MTT).
Patients And Methods: Thirty-eight male patients with a stabilized advanced RCC on MTT were proposed a personal interview about their sexual life, filled in the International Index of Erectile Function (IIEF) auto-questionnaire, and were reassessed if the treatment was modified.
Cisplatin-based chemotherapy (MVAC : cisplatin, methotrexate, adriamycin, vinblastine ; or GC : cisplatin, gemcitabine) has been the standard of care for patients with advanced urothelial tumor during the last twenty years. Greater knowledge in the molecular biology of bladder cancer lead to the identification of promising target such as EGFR, HER2, or VEGF-VEGFR pathways. The role of targeted therapies as monotherapy, in combination with chemotheray or as maintenance post-chemotherapy is currently under study.

Patients And Methods: We retrospectively reviewed 277 patients treated for a pT1aN0M0 PRCC selected from an academic database from 12 centres. We compared the clinico-pathological features by using Chi-square and Student statistical analyses.
Advanced renal cell carcinoma is associated with a poor prognosis and is refractory to standard chemotherapy. Recent progress in the understanding of molecular biology and pathogenesis of renal cell cancer has been translated into the development of new therapeutic strategies. The management of metastatic RCC has been revolutionized with the development of targeted molecular therapies against VEGF-VEGFR and mTOR.

Objective: To determine clinical or pathologic features associated with ipsilateral recurrence after NSS performed for renal cell carcinoma (RCC).
Design, Setting, And Participants: We analysed 809 NSS procedures performed at eight academic institutions for sporadic RCCs retrospectively.
Objective: To evaluate the interest carried in andrology within the community of the urology residents.
Material And Methods: Between June and October 2008, all urology residents received an anonymous questionnaire by e-mail estimating their interest for andrology. The following elements were reported: age, sex, current status, future activity, participation in theoretical learning and training courses practices, interest for the speciality and the opinion on the current formation.
Purpose: The objective was to identify the number of residents registered in the course of urology in France in 2008, and to make a forecast in the number of posts of fellow and specialist assistant available at the end of their course.
Material: From January to February 2008, a questionnaire identified in all French University Hospital the number of residents enrolled in the urology course, and the number of posts of fellow and specialist assistant in urology in the region. The year of the end of the course has been determined for each resident in compliance with seniority, and taking into account the availability.
Objectives: To assess cancer-specific survival of partial nephrectomy (PN) patients with >or= 7-cm lesions or unfavorable pathology (stage T3a or Fuhrman grades III-IV).
Material And Methods: At 13 participation centers, 4072 partial or radical nephrectomies (RN) were performed for RCC between 1984 and 2001. Of all procedures, 925 (22.
Background: The occurrence of positive surgical margins (PSMs) after partial nephrectomy (PN) is rare, and little is known about their natural history.
Objective: To identify predictive factors of cancer recurrence and related death in patients having a PSM following PN.
Design, Setting, And Participants: Some 111 patients with a PSM were identified from a multicentre retrospective survey and were compared with 664 negative surgical margin (NSM) patients.

In this paper, after an overview of the literature concerning the imaging technologies applied to skin wounds assessment, we present an original approach to build 3-D models of skin wounds from color images. The method can deal with uncalibrated images acquired with a handheld digital camera with free zooming. Compared with the cumbersome imaging systems already proposed, this novel solution uses a low-cost and user-friendly image acquisition device suitable for widespread application in health care centers.

This paper is concerned with the 3D modeling of skin wound using uncalibrated vision techniques for the volumetric assessment of the healing process. We have developed an original approach for matching two color images captured with a free-handled digital camera and generate a semi-dense 3D model. We evaluate the precision of the inferred 3D model by registration to a ground truth on artificial wounds.

However, most authors recommend surgery as the treatment of choice for pancreatic metastasis (PM). Resection of the inferior vena cava (IVC) is rarely done during removal of peripancreatic cancer.

Its action has now been clearly demonstrated and it is now widely used for the treatment of neurogenic overactive bladder. Can botulinum toxin also constitute an effective treatment for benign prostatic hyperplasia (BPH)? Intraprostatic botulinum toxin injections have been shown to have a significant clinical and urodynamic efficacy by acting on both the static and dynamic components of BPH.
