Malignant retroperitoneal fibrosis: MRI characteristics in 50 patients.

We analyzed magnetic resonance imaging (MRI) morphologic patterns of retroperitoneal fibrosis (RF) to identify those able to distinguish malignant RF (mRF) from idiopathic RF (iRF). This retrospective study concerned 50 consecutive patients with MRI-based RF diagnoses, 35 of whom also had histologically proven RF. Previous radiotherapy, abdominal or pelvic surgery or infection during the preceding 6 months, vascular aneurysm (aorta or iliac artery), presence of retroperitoneal multiple nodular masses, or enlarged lymph nodes with a diameter >15 mm constituted exclusion criteria.

Purpose: We evaluated quality of life in adults with bladder exstrophy-epispadias complex to improve patient and parent counseling.

Materials And Methods: We evaluated quality of life in a multicenter study using the SF-36® Medical Outcome Study questionnaire and a local questionnaire. A total of 47 patients born in 1957 to 1990 were followed due to bladder exstrophy-epispadias complex at the 4 participating hospitals.

[Sporadic upper urinary tract urothelial cell carcinomas: identification of interaction between toxic carcinogens and individuals genetic susceptibility].

Upper urinary tract urothelial cell carcinomas (UUT UCC) are rare sporadic tumors. Recent epidemiologic and molecular data have shown a singular susceptibility of UUT UCCs for specific risk factors. The main exogenic factors involved in UUT UCCs carcinogenesis remain tobacco and occupational exposure (aromatic amines, polycyclic hydrocarbures and chlored solvents).

Environmental factors involved in carcinogenesis of urothelial cell carcinomas of the upper urinary tract.

Primary cancers of the ureter and renal pelvis are rare tumours, > 90% of which are transitional cell carcinomas. Only approximately 5% of urothelial tumours arise in the upper urinary tract (UUT). Many environmental factors contribute to the development of these cancers.

Biofeedback therapy in the treatment of bladder overactivity, vesico-ureteral reflux and urinary tract infection.

Objective: Voiding disorders are commonly encountered in paediatric urology practice. Urinary incontinence often leads to the impairment of self-esteem but can also cause renal damage, when recurrent urinary tract infection (UTI) or vesico-ureteral reflux (VUR) exists. The aim of this study was to assess the efficacy of a biofeedback training program in children with a long history of voiding disorders.

The use of partial nephrectomy in European tertiary care centers.

Purpose: The objective was to define the trends of PN use over time at six tertiary care European centers.

Methods: Data were retrieved from institutional databases for patients treated with either PN or radical nephrectomy (RN) for stages T(1-2)N(0)M(0) renal cell carcinoma (RCC) between 1987 and 2007. For purpose of temporal trend analyses patients were divided into five equally sized groups according to the date of surgery.

Dynamic contrast-enhanced MRI of anterior prostate cancer: morphometric assessment and correlation with radical prostatectomy findings.

The purpose of the study was to relate morphometric features of prostate cancers in the anterior compartment of the prostate by dynamic contrast-enhanced (DCE) MRI to subsequent histopathologic findings. We prospectively performed DCE-MRI before biopsy in patients with suspected prostate cancer and selected those showing both a suspicious lesion at MRI and positive biopsies in the anterior compartment of the gland. Tumor contours, margins, largest surface areas and volumes were assessed at MRI and histopathology, when available.

Results of endoluminal occlusion of the inferior vena cava during radical nephrectomy and thrombectomy.

Background: The surgical management of renal tumours with thrombi in the inferior vena cava (IVC) has become the gold standard treatment.

Objective: To evaluate endoluminal occlusion of the IVC during radical nephrectomy with either retrohepatic (level II) or suprahepatic (level III) caval tumour thrombus.

Design, Setting, And Participants: From January 2000 to October 2007, 28 consecutive patients with renal cell carcinoma presenting a thrombus level II or III were treated with endoluminal occlusion of the free IVC cranial.

Retroperitoneal infiltration as the first sign of Erdheim-Chester disease.

We report a case of an elderly man with bladder cancer, in whom the first manifestation of Erdheim-Chester disease was retroperitoneal infiltration detected during routine follow-up. The disease was diagnosed on the basis of histology and immunochemistry findings (presence of histiocytes) and of imaging findings (plain radiography, computed tomography, magnetic resonance imaging, and bone scintigraphy). The differential diagnosis with respect to other causes of retroperitoneal infiltration is discussed.

[Observational survey on variations of prostate cancer incidence by stage in the Nord-Pas-de-Calais region between 1998 and 2004].

Objective: The aim of this work is to study variations of prostate cancer incidence by stage as a function of time and place in a region of France.

Material And Methods: Retrospective observational survey conducted in five private and public urology centres representative of the various demographic features of the Nord-Pas-de-Calais region. In each centre, the medical records of the first 25 cases of prostate cancer diagnosed in 1998, 2002 and 2004, identified from histology laboratory data, were studied by means of a case report form evaluating the circumstances of diagnosis, PSA level, grade, stage (TNM 97, classification) and initial management.

[Gastric or duodenal metastases from clear cell renal cell carcinoma. Report of two cases and review of the literature].

Introduction: Gastric or duodenal metastases from clear cell renal cell carcinoma are exceptional. According to autopsy series, the incidence of gastrointestinal metastases is 0.06 to 4% for all cancers and 0.

Prognostic value of combined p53 and survivin in pT1G3 urothelial carcinoma of the bladder.

pT1G3 bladder tumors have a high tendency to recur and progress. We evaluated the prognostic values of the depth of submucosal invasion and immunostaining with survivin and p53 in 30 pT1G3 urothelial carcinomas at the first endoscopic resection. The depth of invasion was evaluated toward the muscularis mucosa and measured using a micrometer.

Tumour necrosis in chromophobe renal cell carcinoma: clinical data to distinguish aggressive variants.

Aim: To assess correlation between necrosis on imaging and pathology reports and prognostic value of tumour necrosis in chromophobe renal cell carcinoma (CRCC).

Methods: Cases were extracted from a prospective renal cancer registry set up in January 2000 containing 470 patients who had surgery for renal cancer in our institution. We reported the outcome of this series and assessed prognostic significance of clinical and pathologic characteristics.

[The female urogenital system and high level sports].

High-level competition sports can have a variety of negative effects on the female urogenital apparatus. Perineal trauma is rare and is usually associated with certain sports (impalement or hydrotubation during water-skiing, indurated perineal nodules in racing cyclists, and horse-riders' perineum). Effort incontinence is seen in all sports involving abrupt repeated increases in intra-abdominal pressure that may exceed perineal floor resistance.

[Ureteric and bladder involvement of deep pelvic endometriosis. Value of multidisciplinary surgical management].

Objectives: To evaluate the clinical features, staging by medical imaging, treatment strategy and results of surgical management of deep pelvic endometriosis with bladder and/or ureteric involvement.

Materials And Methods: Eighteen cases of ureteric and/or bladder deep pelvic endometriosis (DPE) were treated in our centre between 1996 and 2004. Preoperative data (clinical symptoms, MR imaging), intraoperative data (resection and urinary tract diversion procedures, associated procedures on the genital and gastrointestinal tracts), and postoperative data (histological results, complications, anatomical follow-up by imaging and functional assessment) were reviewed.

[Trauma to the anterior urethra: diagnosis and management].

Injuries to anterior urethra are uncommon, mainly due to blunt trauma, and rarely associated with pelvic fractures or life threatening multiple lesions. Straddle type injury is the most frequent lesion, in which the immobile bulbar urethra is crushed or compressed on the inferior surface to the pubic symphysis. Diagnosis of urethral injury is easy, suspected due to trauma circumstances, presence of urethrorragy or initial hematuria, and eventually difficult micturition and penile scrotal for perineoscrotal hematoma.

[Urethral duplication in an adult. A case report].

Urethral duplication is a rare congenital anomaly, essentially diagnosed during adulthood. There are many anatomical variants and many, different classifications. This case report presents an uncommon form of incomplete sagittal urethral duplication with a blind intraprostatic proximal extremity.
