[Vitreous hemorrhage as the initial manifestation of familial exudative vitreoretinopathy in an eight-year-old child]. / Une hémorragie intravitréenne comme manifestation initiale de vitréorétinopathie exsudative familiale chez un enfant de huit ans.

PURPOSE: To report vitreous hemorrhage as the initial manifestation of familial exudative vitreoretinopathy (FEVR). METHODS: Case report. RESULTS: An 8-year-old child presented with vitreous hemorrhage leading to the discovery of large neovascularization. Fundus examination and fluorescein angiography showed the typical appearance of FEVR. A genetic study confirmed the diagnosis. Treatment by laser photocoagulation was performed with good recovery of visual acuity. CONCLUSION: Ophthalmologists should be aware of familial exudative vitreoretinopathy (FEVR) so as not to misdiagnose this sight-threatening disease.

[Assessment of postoperative pain after corneal collagen cross-linking by iontophoresis vs the rapid epithelium-off technique in progressive keratoconus patients]. / Évaluation de la douleur en postopératoire de cross-linking du collagène cornéen en comparant la procédure par iontophorèse à la technique épithélium-off rapide chez des patients atteints de kératocône évolutif.

INTRODUCTION: Cross-linking (CXL) increases corneal biomechanical strength in progressive keratoconus. Since riboflavin cannot penetrate intact corneal epithelium, removal of epithelium is necessary for the classic CXL procedure (epi-off), but can cause severe postoperative pain. To avoid this problem, a method preserving the epithelium (epi-on) is used. In this study, we aimed to evaluate and compare postoperative pain after epi-off CXL and epi-on CXL. MATERIALS AND METHODS: We present a retrospective study assessing the level of pain postoperatively in 38 patients between the age of 12 and 53 years who underwent CXL procedures at the University Hospital of Clermont-Ferrand from July 2013 to May 2014. Epi-off consisted of manual corneal de-epithelialization and riboflavin instillation for 20minutes, followed by UVA exposure for 9minutes. The epi-on technique used an applicator on the eye, filled with riboflavin, and a generator delivered a continuous low-level current for 5minutes. The duration of light exposure was similar in both groups. Postoperative medications were the same for both techniques. Assessment of pain and analgesic intake were reported by the patient on paper questionnaires. Pain was evaluated from preoperatively up until the end of the month. Statistical analyses were performed in bilateral formulation to an alpha type I and error risk of 5%. RESULTS: Twenty-three epi-off patients and 15 epi-on patients. Twenty-nine men and 9 women (76.3%/23.7%). Mean age: 28 years. Reference base time was the return from the operating room. In the epi-off group, pain increased significantly until the morning of D2 and did not return to its intraoperative level until noon D2, 1.8±2.0 vs 2.5±2.5 (P=0.12). Pain remained stable until the morning of D4. From noon D4 until D30, it was significantly less than intraoperatively 1.8±2.0 vs 0.7±1.4 (P=0.01). In the epi-on group, pain was significantly higher than intraoperatively until noon of D1 2.5±2.2 vs 3.8±2.5 (P=0.01). From the evening of D1, it returned to its intraoperative level until the evening of D2 2.5±2.2 vs 2±1.7 (P=0.34). From the morning of D3 it was significantly less than intraoperatively 2.5±2.2 vs 0.8±0.9 (P=0.001). Considering all measurement times, there was no significant difference between the two groups (P=0.75), except from evening of D2 until evening of D3 in favor of iontophoresis: 1.9±2.3 vs 1.0±1.3 (P=0.038). DISCUSSION: Epi-on seems less painful in the short term (up to noon of D1 for epi-on vs morning of D2 for epi-off) and with a shorter duration than epi-off. This can be explained by the absence of corneal de-epithelialization. However, the reduction in pain is not significant at all postoperative times, and a risk of epithelial abrasion during placement and removal of the corneal applicator may exist. CONCLUSION: Iontophoresis maintains the corneal epithelium, decreases pain and improves patient comfort. A new study involving more patients and strict monitoring of medication intake would strengthen the validity of these results.

[Predictable access to the fellowship of urology in France till 2016: an update of the AFUF]. / Accessibilité prévisible au post-internat d'urologie en France jusqu'en 2016: une mise à jour de l'AFUF.

PURPOSE: To evaluate the predictable accessibility to the fellowship of urology for residents expecting to accomplish their residentship from November 2013 to November 2016. MATERIAL: Between September and November 2013, the representants of the residents ongoing for the residentship of urology in each region of France were reached to participate to the study. A questionnaire was given in aim at reporting all the local residents expecting to accomplish their residentship between November 2013 and 2016, and the number and the expected availability of fellow and specialist assistant posts in the region during the same period. RESULTS: In November 2013, our study listed 334 junior urologists (197 residents, 81 fellows, 56 assistants). Fifty-five residents were ending their internship by November 2013, whereas 67, 50, 77 residents were expecting to accomplish their residentship from November 2014 to 2016 respectively. The predictable accessibility to the fellowship of urology was 96.4%, 82.1%, 90.0%, 74.0% respectively for the residents accomplishing their residentship from November 2013 to November 2016. The predictable deficit of fellow and assistant posts were -2, -12, -5, -20 posts from November 2013 to November 2016 respectively. CONCLUSION: The predictable number of fellow and assistant post in Urology remains insufficiently available for the 2013-2016 period. By reason of the unstable number of residents accomplishing their residentship from 2014 to 2016, the fellowship accessibility was measured at 82.1%, 90.0%, 74.0% from 2014 to 2016 respectively.

[Head to head comparison of two currently used nomograms predicting the risk of side specific extra capsular extension to indicate nerve sparing during radical prostatectomy for treatment of prostate cancer]. / Validation externe des nomogrammes de prédiction de l'extension extra-prostatique spécifiquement au côté pour des patients atteints de cancer de prostate traités par prostatectomie totale.

OBJECTIVE: To perform a head to head comparison of these two nomograms by an external validation combined with an identification of probability cut-offs when to indicate NS. METHODS: The full models of the nomograms of Ohori et al. and Steuber et al. were used to calculate the risk of ECE based on PSA and side specific information on clinical stage, biopsy Gleason score, % positive cores, and % cancer in cores. A dataset of 968 prostate half lobes was used retrospectively for analysis. All patients underwent laparoscopic robot-assisted or open radical prostatectomy for localized prostate cancer. RESULTS: The predictive accuracy of the Ohori nomogram was at 0.80 and for the Steuber Nomogram at 0.78 (comparison P > 0.05). In the calibration plot, the Ohori nomogram showed less departures from ideal predictions than the Steuber nomogram. The best probability cut-off to allow NS for the Ohori nomogram seemed to be ≤ 10%, permitting NS in 59.7% of all cases and being associated with a false negative rate of 10%. The best cut-off for the Steuber nomogram seemed to be ≤ 8%, permitting NS in 44% and associated with a false negative rate 12.5%. CONCLUSIONS: The Ohori et al. and the Steuber et al. nomograms allow highly accurate and comparable predictions of the risk of side specific ECE. LEVEL OF EVIDENCE: 4.

[Current state of compensation of on-duty and on-call urologists in France: a study from AFUF]. / État des lieux des rémunérations des gardes et astreintes d'urologie en France: une étude de l'AFUF.

INTRODUCTION: The French Association of Urologists-in-training (AFUF) aimed to assess the current state of remunerations of on-call and on-duty residents, assistants and lecturers in urology in France. MATERIAL AND METHODS: Data were collected from February to May 2013 through a questionnaire sent to all members of the AFUF (327 members). Remunerations were given in gross values. RESULTS: Forty-three residents took part in the study, 16 assistants and 16 lecturers, representing 62 % of the whole centers (54 hospitals out of the 92 centers practicing urology in France). Most of responders were on security or operational on-call. Twenty hospitals were practicing multi-organ removal. Median remunerations of residents were about 59.51€ per on-call when moving at hospital for work and about 119.02€ per onsite duty. Assistants and lecturers were paid a flat fee rate for 37.5 % of them (140€ for assistants [with variability from 40 to 195€] and 130€ for lecturers [42.5-180]) or an hourly rate depending on the hours spent at hospital for the others (62.5 %): first, second move or move<3h were paid 100€ for assistants and 65€ for lecturers, 233.5€ and 236€ respectively for the third one or above 3h, 365€ and 473€ respectively above 8h. Multi-organ removals were paid a flat fee rate (60 %) or an hourly rate (40 %) as well. Beyond a threshold of 2-3hours, the hourly rate was more interesting than the flat fee rate. CONCLUSION: There were disparities in remuneration of on-call and on-duty urologists. Greater variability affected on-call flat fee rate remuneration beyond a certain threshold of hours and remuneration of multi-organ removal. These disparities should be considered in order to get a national harmonization.

[Giant renal angiomyolipoma with right heart failure]. / Angiomyolipome rénal géant compliqué d'insuffisance cardiaque droite.

We report the case of a 63-year-old woman presenting a 26cm right renal angiomyolipoma with intratumoral arteriovenous fistula responsible for a high-output right heart failure. A radical surgical treatment after preoperative embolization allowed rapid improvement of cardiac symptoms with an uneventful postoperative course.

[Treatment by radiofrequency ablation for a renin-secreting juxtaglomerular tumour: a case report]. / Traitement par radiofréquence d'une tumeur de l'appareil juxta-glomérulaire sécrétant de la rénine. À propos d'un cas.

Juxtaglomerular cell tumors are rare and benign tumors, occurring in young patients. The standard treatment is partial nephrectomy. We report the case of a young 22-year-old patient with a renin-secreting tumor diagnosed during an exploration of severe hypertension associated with hypokalemia that we treated by radiofrequency ablation.

[Research fellowship in the curriculum of French urologists-in-training: a study by the French Association of Urologists-in-training (AFUF)]. / Place du Master 2 recherche dans la formation des jeunes urologues français : une étude de l'AFUF.

OBJECTIVES: To assess motivations, the practical organization and the funding of a research fellowship in the training curriculum of French urologists-in-training. MATERIALS AND METHODS: An online questionnaire was sent to members of the AFUF and to participants of a research training seminar "Graines et Sol" organised by the AFU, between July and September 2013. Results are presented as the median (interquartile range). RESULTS: Sixty answers out of 115 research fellows (response rate 52%) were computed. Median age was 29 years (28-30) during the research year and male proportion 75%. The AFU grant was obtained by 57.4% of applicants, 56.4% for various grants and 47.6% for the research fellowship university grant. The annual gross amount was 29,870€ (22,710-30,195), without any significant difference between residency subdivisions. Financial supplements were obtained by being on-duty (26.2%), on-call (28.6%) and replacements (25%). The research fellowship year was done between 4th and 5th years of residency (53%), for a one-year length (96.7%) and in France (86.6%). Urologic cancerology was the thematic the most studied (60%). The research fellowship was done in view of an academic career (31.7%) or was done to wait for a post-residency position (20.8%). About a quarter was being proposed a chief-residency position before the beginning of the research year. During this year, 76.7% published. About 63% were interested in pursuing with a PhD. CONCLUSION: This study confirmed the interest for a research fellowship by French urologists-in-training. Financial support thanks to grants facilitated the conduct of a research fellowship in the aim of an academic career for most of them.

[The role of simulation in the curriculum of French urologists-in-training: a study by the French Association of Urologists-in-Training (AFUF)]. / Évaluation de l'utilisation de la simulation dans la formation des jeunes urologues français : une enquête de l'association française des urologues en formation (AFUF).

OBJECTIVES: To study the place of simulation in the training curriculum of French urologists-in-training. MATERIALS AND METHODS: An online questionnaire was sent to all residents and fellows members of the AFUF between February and May, 2013. Results are presented as the median (interquartile range). RESULTS: The answers of 125 urologists-in-training were computed (response rate 38%). They were residents in 90 cases (72%), and fellows in 35 cases (28%). Median age was 29 (27-30), male proportion 77%. All French academic urology departments were represented. Ninety of them (72%) had access to a pelvi-trainer and 66 (53%) to animal or cadaveric models, although they never used them or less than once a month in 83 and 97% of cases, respectively. Seventy-two (58%) had used a virtual-reality based simulator at least once and 38 (30%) had regular access to one, but without supervision in 64% of cases. Factors limiting simulation-based training were the lack of available simulators (70%), the lack of time (58%), the absence of incitement (34%) and supervision (20%). If these conditions were met, 86% of urologists-in-training would be ready to spend more than one hour a-week training on a simulator. CONCLUSION: This study revealed among the sample of respondents a limited use of simulation tools for skills aquisition. This was explained by a limited availability of these tools but also by an insufficient use of the tools when available.

[Non palpable testicular tumors. Retrospective series]. / Tumeurs testiculaires non palpables. Série rétrospective.

OBJECTIVE: To report our experience in 13 cases with nonpalpable testicular tumors and review the literature. MATERIAL AND METHODS: From 1998 to 2012, 13 patients were diagnosed with nonpalpable testicular tumors. The data base was performed prospectively, and analyzed retrospectively. We evaluated demographic data, clinical presentation, ultrasound tumor features, tumor markers, frozen and final histopathological findings. All patients were also evaluated with serum tumor markers and the surgical approach was inguinal. RESULTS: The mean age was 46.4 years and the most frequent clinical presentation were orchialgia in six patients (46.1%) and infertility in three (23%). All masses were hypoechoic with an average tumor size of 8.9 mm. The serum tumor markers were negative in all patients and the final histopathological findings were six seminomas, two embryonal carcinomas, one seminiferous tubules atrophy, a segmental testicular infarction, a Sertoli cell tumor and a Leydig cell tumor. CONCLUSIONS: Nonpalpable testicular masses were benign in almost half of the cases; therefore, we recommend using the frozen section pathology as a tool to perform conservative surgery in selective cases.

Predictive factors of chronic kidney disease stage V after partial nephrectomy in a solitary kidney: a multi-institutional study.

OBJECTIVE: Partial Nephrectomy (PN) in a solitary kidney is at risk of chronic kidney disease (CKD) stage V and/or haemodialysis (HD). Our objective was to determine predictive factors of CKD stage V in this population. MATERIAL & METHODS: Data from 300 patients were retrospectively collected from 16 tertiary centres. Clinical and operative parameters, tumor characteristics and renal function before surgery were analyzed. Patients with and without CKD stage V (defined as MDRD<1 5 ml/min) were compared using χ2 and Student-t tests for qualitative and quantitative variables, respectively. Predictive factors of CKD stage V were evaluated with a multivariable analysis using a Cox regression model. RESULTS: Median age and BMI were 63 years old and 26 kg/m², respectively. Most of the patients (65%) were male with an anatomic solitary kidney (88.3%). Median tumor size was 4 cm and 98% were malignant tumors. Median operative time, blood loss and clamping time were 180 min, 350 ml and 20 min respectively. Renal cooling was used in 19.3% and clamping of the pedicle was performed in 61.6%. Twenty five patients (8.5%) presented post operative CKD stage V at last follow-up and 18 underwent HD (6%) post-operatively because of acute renal insufficiency. There was no difference between CKD stage V and non CKD stage V patients concerning Charlson index, operative time (180 min vs 179 min, p = 0.39), blood loss (475 ml vs 350 ml, p = 0.51), use of renal cooling and type of clamping. Patients with CKD stage V were older (70 vs 63 years old, p = 0.005), had a lower baseline renal function (clearance MDRD 41 vs. 62 ml/min, p<0.0001) and an increased tumor size (p = 0.02). Complications occurred in 91 patients (30%) with 16% of minor (Clavien 1-2) and 14% of major (Clavien > 2) complications, respectively. In multivariable analysis, baseline MDRD, BMI, and the occurrence of a minor complication were independent predictive factors of post operative CKD stage V. CONCLUSION: PN in a solitary kidney is at risk of post-operative CKD stage V and HD. Pre-operative altered renal function and post operative complications are the main predictive factors of permanent CKD stage V.

[Renal cancer and hereditary diseases]. / Tumeurs rénales des maladies héréditaires.

Renal tumors associated with hereditary diseases are a rare entity characterized by many renal tumors and other manifestations such as pulmonary, neurological and dermatological expressions. The management requires a close collaboration between surgical specialties and geneticists. Precocious, bilateral and/or multifocal tumors call to mind a hereditary disease. Early diagnosis and screening are essential to optimize a strict observation and a most conservative treatment.

[Comparative study of radical prostatectomy versus external beam radiotherapy (75.6 Gy) combined with hormone therapy for prostate cancer of intermediate D'Amico risk classification]. / Étude comparative des résultats carcinologiques après prostatectomie et radiothérapie externe (75,6Gy) avec hormonothérapie concomitante pour cancer de prostate à risque intermédiaire de D'Amico.

INTRODUCTION: Thirty-three percent of the localized cancers belongs initially to the group of intermediate risk of D'Amico. The standard treatments validated by the French Association of Urology are the radical prostatectomy and the external beam radiotherapy. OBJECTIVES: We retrospectively compared the carcinologic results of the radical prostatectomy±adjuvant treatment (RP) and the external beam radiotherapy combining high dose (75.6 Gy) and short hormonotherapy (RH), in the treatment of intermediate risk prostate cancer. The series consisted of 143 patients treated between 2000 and 2006 in the department of Urology and Kidney transplantation of the Conception Hospital, Marseilles. The main assessment criteria was the survival without biological recurrence (SBR). RESULTS: The median follow-up was 90 months [59-51]. The 5 years and 8 years SBR were 85% and 73% in the RH group, versus 74% and 65% with RP (P=0.196). There was a significant difference between the series: on the age of diagnosis (63.9 versus 73.3 years, P<0.001), the Charlson score of comorbidity (2 versus 3, P<0.001) and the number of intermediate criteria per patients (one intermediate criteria: RP 74% versus 57%, P<0.01). CONCLUSION: According to our study, there was no superiority of the radical prostatectomy±adjuvant treatment or the external radiotherapy combining high dose and concomitant short hormonotherapy on the survival without biological recurrence at 5 and 8 years. Many studies confirm that a concomitant hormonotherapy increases the carcinologic control, even with a high rate external beam radiotherapy.

An experimental porcine model of heterotopic renal autotransplantation.

OBJECTIVE: The aim of the present study was to validate an experimental model of heterotopic renal allotransplantation. Such a model, more relevant to the human situation, has never been previously described. MATERIALS AND METHODS: Pietrin pigs (40 to 50 kg) were used in the study. Through a midline incision, the left kidney was removed, washed, and preserved in a standard preservation solution (Celsior, Genzyme, France) for 20 hours at 4 °C. Heterotopic autotransplantation was performed into the right iliac fossa onto the external iliac vessels with an end-to-side anastomosis and a nonstented uretero-ureteral anastomosis was performed. RESULTS: Twenty-five renal allotransplantations were performed over a 5-month time period. Mean operating time progressively decreased and stabilized after 15 procedures (mean ± SD: 78.2 ± 19 minutes and 187.4 ± 18 minutes for left nephrectomy and transplantation, respectively) as morbidity decreased concomitantly. Suturing times for end-to-side anastomosis of the renal artery and vein onto the external iliac artery and vein were 21.9 ± 7 minutes and 34 ± 8 minutes (mean ± SD), respectively. Ten pigs died before the end of the experiment. CONCLUSIONS: We have developed and validated the first nonrodent animal model of heterotopic renal autotransplantation relevant to the human anatomy and physiology. The procedure was easy to learn and safe. This model could be used to teach junior surgeons renal transplantation techniques and could also be used as a model to study ischemia-reperfusion injury in renal transplantation.

[Cryptorchidism associated with ectopic adrenal cortical tissue in the spermatic cord in a 51-year-old male]. / Un cas de cryptochidie associée à un îlot surrénalien ectopique du cordon spermatique chez un homme de 51ans.

This case report describes an exceptional case of ectopic adrenal cortex tissue (EACT) in the spermatic cord associated with ipsilateral cryptorchidism in an adult. While both EACT and cryptorchidism are fairly common congenital anomalies in boys, adult cases are uncommon. Although the spermatic cord is a known site of EACT, the reports of its association with cryptorchidism have been limited to child cases. During surgery, undescended testis was discovered and incidentally ectopic adrenal tissue along the spermatic cord was also identified. This combination of developmental aberrations in the adult has not been described, and the clinicopathological findings are reported with a brief literature review.

[Post-traumatic small-bowel obstruction: two case studies]. / Sténoses post-traumatiques du grêle chez l'enfant : à propos de 2 cas.

Post-traumatic small-bowel obstructions are rare and late complications following blunt abdominal trauma. Timely diagnosis is frequently impeded because of nonspecific associated symptoms, and furthermore, the degree of urgency is frequently underestimated due to the accidental cause. During the last 6 years (2005-2011), we have observed only 2 cases (4 and 10 years old) with post-traumatic small-bowel obstruction. On admission the patients had a contusion on the abdominal wall, duodenal hematoma and a Chance fracture of the lumbar spine on the computed tomography (CT) scan. Although early clinical improvement was noted, progression of the disorder was observed for the following 15 days like an occlusive syndrome (abdominal distension, nausea, emesis). Abdominal ultrasound and computed tomography scan revealed small-bowel obstruction. At laparotomy, jejunal stenosis was found associated with mesenteric tears, which was resected with end-to-end anastomosis. Six to 8 months of follow-up ascertained the therapeutic efficacy of the procedure. Post-traumatic small-bowel obstructions are rare; the clinical presentation is unspecific and appears with a time lag following the trauma. Echography and computed tomography scan can establish both the diagnosis and therapeutic choice.

[What is the role of active surveillance for small renal masses?]. / Quelle place pour la surveillance active des petites tumeurs rénales ?

Incidence of small renal masses (SRM) T1a is increasing in every age group. In relation to their characteristics, treatments seem to become less invasive. This article summarizes data about Watchful Waiting. A literature review based on Pubmed and keywords "petites masses rénales", "small renal masses", "rein", "kidney", "tumeur", "tumor", "surveillance", "watchful waiting" was done. Fifty-eight english and french articles including cohort-following and meta-analysis were selected. Considering indolence and harmless of the SRM, watchful waiting is nowadays a valid therapeutic option: in most of the series is tumoral growing lower than 0.40cm per year, metastatic evolution approaches 1 to 2% (except in the Kouba et al. study with 5,7%) and disease-free survival is 100%. Nevertheless, this option seems to be appropriate after carefully selection of the patients (age, conciliance, comorbidities, imperative indications…) and the tumors (tumor size, localization, histology…). Watchful waiting is a promising alternative after selection of the SRM. Large-scale and long-term studies will precise the global cost and modalities of this therapeutic option.
