[Elastography shows promise in testicular cancer detection]. / Apport de l'élastographie en temps réel pour la caractérisation des masses testiculaires.

PURPOSE: Elastography is a novel imaging technology that shows promise in the identification of anatomic structures. The widespread use of ultrasound for screening testicular tumors in patients with cancer risk factors highlights unclassified testicular micronodules. We investigated the ability of elastography to accurately diagnose testicular nodules. MATERIAL: Patients with clinical testicular nodules were assigned to undergo elastography in a prospective study. The imaging was carried out by a single radiologist using a static elastography unit with a 9-14MHz frequency linear transducer, to identify hardness score, loss of architecture of testicular parenchyma, and surrounding effect. When orchidectomy was required, the corresponding specimens were subjected to hematoxylin and eosin staining for histologic correlation. RESULTS: We imaged 34 testicular lesions: 26/34 (76%) malignant tumors and 8/34 (24%) non-tumor lesion including 4 hematomas, 3 orchitis and 1 ischemia. Se, Sp, PPV and NPV of hardness in elastography in differentiating between malignant and benign tissue was found to be 96.2%, 37.5%, 83%, and 75%, respectively. Further, for recognizing cancer, the loss of architecture of the testicular parenchyma detecting in elastography was 92.3%, 75%, 92.3%, and 75%, respectively, and the surrounding effect was 84.6%, 87.5%, 95.6% and 63.6%, respectively. CONCLUSION: Elastography may be a promising tool at diagnosing testicular tumor when the loss of architecture and the surrounding effect were present. Further studies are needed to evaluate whether the utility of elastography is worth pursuing to identify of unclassified testicular micronodules. LEVEL OF EVIDENCE: 3.

[Obstructive pyelonephritis caused by ureteral orifice catheterization with a bladder catheter]. / Pyélonéphrite obstructive par cathétérisation du méat urétéral par une sonde vésicale.

This article reports a rare case of acute pyelonephritis secondary to left ureteral obstruction by a bladder catheter. The patient was 93years old man hospitalized in the hospital emergency department with a 39°C fever and pyuria from an indwelling catheter. Blood test found hyperleukocytosis, inflammatory syndrome and acute renal failure. Diagnosis was confirmed by non-contrast abdominal CT scan showing distal part of the catheter inside left ureteral orifice with ureterohydronephrosis. Treatment consisted in replacing the catheter by a three-way catheter for irrigation and parenteral antibiotics therapy. Clinico-biological evolution was successful and a urinary tract CT scan could be realized at day 9. The left upper urinary tract function was recovered. With a short review of the literature we propose to describe the different procedures to manage those obstructions.

[Update for the management of kidney stones in 2013. Lithiasis Committee of the French Association of Urology]. / Mise au point sur la prise en charge des calculs du rein en 2013. Comité Lithiase de l'Association française d'urologie.

Since the publication of the latest recommendations of the Lithiasis Comity of the French Association of Urology (CLAFU) on the management of ureteral and renal stones, practices have evolved. This text provides an update for the treatment of kidney stones. It is especially the important advances in the field of laser-ureterorenoscopy that changed practices. Percutaneous nephrolithotomy has been enriched by technical modifications and extracorporeal shockwave lithotripsy confirmed its predominant place in the first line of treatment. For stones less than 20mm, extracorporeal lithotripsy remains the standard, but in some cases the possibility of recommending a flexible ureterorenoscopy is possible in first line. For stones more than 20mm, percutaneous nephrolithotomy is the standard treatment, but optional flexible ureteroscopy and extracorporeal lithotripsy are possible. The treatment carried out, collect the stone fragments for a morpho-constitutional analysis and achieve a metabolic evaluation is necessary, to investigate etiologic and give dietary advices to prevent recurrence.

[Ipsilateral dual kidney transplantation: a monocentric experience about 15 cases and literature review]. / Bi-transplantation rénale par abord ipsilatéral: expérience d'un centre à propos de 15 patients opérés consécutivement et revue de la littérature.

OBJECTIVE: Our study aimed to support the viability of the concept of Ipsilateral Dual Kidney Transplantation (DKT) by presenting our initial experience and proposing a review of the literature in this subject. METHODS: Fifteen ipsilateral DKT were performed at Nice University Hospital between August 2010 and March 2012. We have described our skin incision preferences, the vascular anastomoses, and the uretero-vesical reimplantation. We have analyzed the operative duration, the cold ischemia time (CIT) of both transplants, the blood transfusion volume, the intraoperative and postoperative complications, the time to diuresis recovery, the hospital stay, and the kinetics of the creatinine clearance until the third postoperative month. We have compared our results with those of the literature. RESULTS: The average CIT of the first transplant (T1) was 17.5 ± 3.3 hours, and that of the second (T2) was 18.4 ± 3.3 hours. The mean operating time was 234 ± 67 minutes. Patients received an average of 2 units of blood during surgery [0-4] and 1.8 units in the postoperative period [0-15]. The complications rate was 26.7% and included an intraoperative T2 artery thrombosis and 3 postoperative complications consistent with a hematoma, a T2 ureteric necrosis and a T2 venous thrombosis. Two transplants were lost (6.7%) and one death (6.7%) was reported on day 40. The average length of hospital stay was 20.9 ± 7.8 days. The mean creatinine clearance values were 12.6 mL/min at D2, 35.6 mL/min at D7, 44.9 mL/min on discharge, and 48.2 mL/min at D90. CONCLUSION: Our results supported the viability of the dual kidney transplantation concept. Furthermore the ipsilateral approach shortened the procedure and limited the surgical trauma by preserving the contralateral iliac fossa, without compromising renal function recovery or increasing morbidity.

[Management of the bladder cuff removal by open excision versus transurethral resection of the ureteral orifice after laparoscopic radical nephroureterectomy in upper urinary tract--urothelial carcinoma]. / Évaluation des différentes techniques d'excision de la collerette vésicale lors des néphro-urétérectomies laparoscopiques pour la prise en charge des carcinomes urothéliaux de la voie excrétrice supérieure.

OBJECTIVES: To assess treatment-related complication outcomes in the management of the bladder cuff removal by open excision (OE) or transurethral resection of the ureteral orifice (TURUO) after laparoscopic radical nephroureterectomy (LNU) in upper urinary tract urothelial carcinoma (UUT-UC). PATIENTS AND METHODS: We did a retrospective study involving patients having UUT-UC who underwent LNU from 2004 to 2012 in two references center. Flexible ureteroscopy was carried out for multiple biopsies. Patients were assigned to one of two different surgical groups consisting of LNU with OE versus TURUO for the bladder cuff removal. Perioperative characteristics, complication related treatment and oncological outcomes were collected during the follow-up. RESULTS: Overall, 29 patients underwent LNU over-time including 16 using LNU with OE and 13 LNU with TURUO. LNU+OE were older (66.5 years [48-87] [P<0.01]). Operative time was shorter (180 min vs. 240 min [P=0.01]) with a longer hospital stay (7 days vs. 5 days [P<0.01]) than TURUO technic. No difference in the complication rate was reported. LNU +OE was associated with higher grade (81.3% vs. 38.5% [P=0.026]) and more invasive tumor (37.5% vs. 24.1% [P=0.03]). Regardless the technic, the cancer-specific survival rate was 63.7 years without significant differences between technics. CONCLUSION: TURUO was shorter in hospital stay but had a longer operative time with no impact on the treatment-related complication. Oncological control not highlighted any difference between technics however longer follow up is expected for recommendations.

[Management of adult's renal and ureteral stones. Update of the Lithiasis Committee of the French Association of Urology (CLAFU). General considerations]. / Prise en charge urologique des calculs rénaux et urétéraux de l'adulte. Mise au point du Comité Lithiase de l'Association Française d'Urologie (CLAFU). Aspects généraux.

The Lithiasis Committee of the French Association of Urology (CLAFU) aimed to update the current knowledge about urolithiasis. This update will be divided into four parts: 1) general considerations; 2) the management of ureteral stones; 3) the management of kidney stones; 4) metabolic assessment and medical treatment of urolithiasis. Recent technicals advances helped the urologists to improve stones management: new extracorporeal shockwave lithotripsy (ESWL) devices, new flexible ureterorenoscopes, development of laser fragmentation. ESWL, semi-rigid and flexible ureteroscopy and the percutaneous nephrolithotomy (PCNL) remain currently the main therapeutic options. The first part of this update deals with the description and classification of stones, preoperative assessment, post-operative management and clinical follow-up. Main criteria of therapeutic choices are stone location, stone composition and stone size. Stone composition is assessed with infrared spectrophotometry analysis and its hardness is correlated with U.H. density on CT scan assessment. Preoperative assessment consists in urinary cytobacteriological examine, urinary PH, blood creatininemia, hemostasis. Low-dose CT scan is recommended before urological treatment. The result of the treatment must be done 1 or 3 months later with plain abdominal film and ultrasonography. Medical management of urolithiasis will be based on stone composition, metabolic and nutritional evaluation. Treatment success is definited by absence of residual fragments. Annual follow-up is recommended and based either on plain abdominal film and ultrasonography or low-dose CT scan.

[Place of the flexible ureterorenoscopy first choice for the treatment of kidney stones. Survey results practice committee of the AFU lithiasis completed in 2011]. / Place de l'urétérorénoscopie souple en première intention pour le traitement des calculs du rein. Résultats de l'enquête de pratique du comité lithiase de l'AFU réalisée en 2011.

UNLABELLED: The flexible ureterorenoscopy coupled with photovaporisation LASER (USSR-L) for the treatment of kidney kidney is a modern tool whose place is under evaluation. METHODS: Its place has been assessed in France in 2010 by the Committee of urolithiasis of the French Association of Urology (CLAFU). A practice survey among 27 experts concerned the following decision criteria: comorbid patient's supposed nature of the calculation, anatomy of the urinary tract of the patient. This investigation has been proposed to calculate the size not exceeding 20mm, for a calculation of size greater than 20mm and for multiple calculations kidney. RESULTS: Fourteen experts responded. The criteria for the USSR-The first line were: morbid obesity (BMI>30), anticoagulation or anti platelet aggregation, calculations Hard (UH>1000, cystine stones), calculations within diverticular caliceal calculations below, the failure of a first treatment or the wish of the patient. CONCLUSION: The URS-SL was a first-line treatment validated regardless of size and number of kidney stones, when ESWL and PCNL were contraindicated or when their predictable results were poor (hard stones/morbid obesity/lower pole stones) or when stone access is difficult (intradiverticular). It was also the treatment of choice after the failure of a first treatment (ESWL/PCNL).

Retroperitoneoscopic vs open dismembered pyeloplasty for ureteropelvic junction obstruction in children.

PURPOSE: To compare the effectiveness, potential advantages and complications of classical open pyeloplasty with retroperitoneoscopic pyeloplasty in children. MATERIALS AND METHODS: Two patient cohorts with confirmed ureteropelvic junction obstruction (UPJO) undergoing open or retroperitoneoscopic pyeloplasty over a 7-year period were analysed comparatively. RESULTS: Operative time was significantly longer in the retroperitoneoscopic group (mean 155 min) compared to the open pyeloplasty group (mean 98 min, P<0.05). Mean hospital stay was shorter in the retroperitoneoscopic group (mean 4.1 days, compared to 5.1 days, open). Complication rates were similar (open, 27% vs retroperitoneoscopic, 29%). These included anastomotic urinary leakage, stenosis and infection. Anastomotic leakage was more common in the retroperitoneoscopic group. There was a 6.6% conversion rate in the retroperitoneoscopic group. Success, defined as improved ultrasonic or renographic parameters, with resolution of symptoms where discernable, was noted in 96% of the open group and 97% of the retroperitoneoscopic group with a mean follow up of 38 and 25 months, respectively. CONCLUSIONS: Retroperitoneoscopic pyeloplasty is as safe and effective as open pyeloplasty. This technique is now our procedure of choice for children>4 months old. The advantages are more obvious in children over 4 years than in infants. This technique remains difficult to perform and teach.

[Evaluation and criteria of choice of urology teaching material used by hospital students to prepare for the national entrance examination]. / Evaluation et critères de choix des supports pédagogiques d'urologie utilisés par les étudiants hospitaliers pour préparer l'examen classant national.

INTRODUCTION AND OBJECTIVES: Preparation for the national entrance examination is a major concern for hospital medical students. Many teaching materials are available to prepare for the urology module: faculty photocopies and general urology texts. The objective of this study was to determine the selection criteria used by medical students to choose their urology teaching materials, in preparation for the national entrance examination. MATERIAL AND METHOD: A questionnaire was distributed to 200 medical students (4th and 6th year students) preparing for the national entrance examination. This questionnaire comprised three parts: (1) information about the student (medical school, attendance of lectures, participation in intern conferences); (2) student's level of satisfaction with the teaching material provided;(3) criteria of choice (18 items) of the photocopies used. RESULTS: Out of the 200 students completing the questionnaire, only 32% used teaching material provided by the university and 22% reported that their medical school did not provide Urology teaching material. Fifty-nine percent of students thought that this teaching material was "moderately" to "not at all adapted" to the national entrance examination programme and 70% considered that they were "moderately" to "not at all" prepared for the national entrance examination. We noted that 83.5% of students thought that intern conferences were "useful" to "very useful" to prepare the urology module of the national entrance examination and 85% thought that photocopies were "useful" to "very useful" to prepare the national entrance examination. The College of urology photocopies were the most widely used teaching material: 38% of students. The four most important criteria of choices were "their peers' opinion", "the style of presentation and writing" and "advice from interns". "The author" and "price" were only rated in 11th and 12th positions. CONCLUSION: In this study, students appeared to consider that the material provided by medical schools was insufficient and poorly adapted to prepare for the national entrance examination in Urology. In contrast, College of urology photocopies appeared to be a satisfactory study tool, in terms of presentation and writing.
