[Impact of obesity on pathologic outcomes and biochemical reccurence after radical prostatectomy].

Objective: To determine whether obesity is associated with adverse pathologic characteristics, positive surgical margins and the biochemical recurrence free survival (bRFS) after primary treatment with radical prostatectomy (RP).

Patients And Methods: Medical charts of patients managed with RP between 1999 and 2011 for localized prostate cancer (PCa) were retrospectively reviewed. Population study was split into two groups according to the body mass index (BMI): non obese (BMI< 30 kg/m(2)) and obese (BMI ≥ 30 kg/m(2)).

[Existence of pattern 5 on radical prostatectomy: poor prognostic factor associated with a lower biochemical recurrence-free survival].

Objectives: To analyze the impact of the existence of Gleason grade 5 on the adverse pathology and biochemical recurrence-free survival of patients.

Patients: Three hundred and seventy-two prostatectomies were performed between 1999 and 2011 in our institution for localised prostate adenocarcinoma. We examined the existence of grade 5 of the specimen to determine the reliability of prostate biopsies in the diagnosis of grade 5 and the association of grade 5 with other histoprognostic factors.

[Evaluation of the activity of a urological emergency unit in university hospital].

Aim Of The Study: To determine the epidemiology of urological emergencies in a university hospital and the interest of a dedicated urological emergency unit.

Patients And Methods: In 2008, a dedicated urological emergency unit was individualized in our department of urology. We conducted a retrospective study including all patients consulting in this unit in 2009 with epidemiological, clinical and therapeutic data.

Risk factors for surgical complications after renal transplantation and impact on patient and graft survival.

Purpose: We report herein the incidence of and factors predisposive to surgical complications (SC) after renal transplantation.

Methods: Between 2004 and 2008, we performed 200 renal transplantation. We retrospectively studied recipient and donor characteristics, cold ischemia time, surgical revision in the month after transplantation, delayed graft function, surgical complications (vascular, urologic, wound, or bleeding), as well as graft and patient 5-year survival rates.

Outcomes of renal transplantation in obese recipients.

Purpose: Although obesity has been shown to paradoxically increase dialysis patient survival, its impact has not been clearly defined on renal transplantation. We assessed outcomes of obesity renal transplant patients by evaluating graft and patient survivals.

Patients And Methods: A single-institution, retrospective study was performed on 202 renal transplant recipients from January 2004 to December 2008 excluding two combined kidney and liver transplantations.

[Accuracy of prostate biopsies to evaluate tumor location in prostate cancer].

Introduction: The therapeutic approach of prostate cancer depends mainly on pathological criteria obtained through prostate biopsy. The low accuracy of prostate biopsy for Gleason grade determination is well known but its accuracy for bilateral or multifocal tumor has not been evaluated. The goal of this study was to assess the concordance between prostate biopsy and whole prostate specimen obtained after radical prostatectomy especially for bilateral and/or multifocal tumor.

[Muscularis mucosae invasion: prognostic factor for intravesical BCG immunotherapy failure for T1 bladder carcinoma].

Objectives: To study the prognostic impact of muscularis mucosae (MM) invasion for pT1 bladder cancer treated by transurethral resection (TUR) and adjuvant Bacille Calmette-Guerin (BCG) intravesical immunotherapy.

Methods: Sixty-six patients treated by BCG intravesical instillations were substaged into pT1a and pT1b, regarding Muscularis Mucosae invasion. Tumor grade, associated carcinoma in situ (CIS), multifocality, tumoral size up to 3cm, BCG maintenance were noted.

[Urinary complications of one-stitch ureteroneocystostomy in renal transplantation].

Purpose: To assess urinary complications related to the "one-stitch" technique extravesical ureteroneocystostomy in renal transplantation, and evaluate the impact of such complications on kidney graft and patient survival.

Patients And Methods: A single-institution, retrospective study was performed on 202 renal transplant recipients, from January 2004 to December 2008. Two combined kidney and liver transplantations were excluded.

Ureterorenoscopy with holmium-yttrium-aluminum-garnet fragmentation is a safe and efficient technique for stone treatment in patients with a body mass index superior to 30 kg/m2.

Purpose: The aim of the study was to analyze results and morbidity after flexible ureterorenoscopy in patients with a body mass index (BMI) >30 kg/m(2) and to compare with results obtained in a large cohort of nonobese patients.

Patients And Methods: We conducted a retrospective study including all flexible ureterorenoscopy performed for stone retrieval in our institution between January 2004 and December 2008. During the study period, 224 procedures were performed, of which 18 had to be excluded because of missing BMI data.

Femorofemoral bypass as an alternative to a direct aortic approach in daily practice: appraisal of its current indications and midterm results.

Background: To assess our current practice concerning the indications and the immediate and midterm results of femorofemoral bypass.

Methods: We retrospectively included all patients, from 1997 to 2008, operated on for aortoiliac occlusive disease using an extra-anatomical bypass from a donor iliac artery or a femoral artery to the contralateral femoral artery (common or profunda artery). Demographic data, initial clinical status, characteristics of the interventions, and short- and midterm results were collected.

Wegener's granulomatosis: a rare cause of hydronephrosis.

A seventy-one-year-old woman was hospitalized at our institution for a right-sided "renal colic" associated with an infectious background. Alithiasic ureterohydronephrosis was diagnosed by imaging. A urinary diversion was thus performed using a double J endoureteral stent.
