Prognostic factors after adrenalectomy for adrenal metastasis.

PURPOSE: Very few studies have sought prognostic factors after adrenalectomy for metastasis. The aim of this study was to assess prognostic factors for oncological outcomes after adrenalectomy for adrenal metastasis. METHODS: All adrenalectomies for metastases performed in seven centers between 2006 and 2016 were included in a retrospective study. Recurrence-free survival (RFS) and cancer-specific survival (CSS) were estimated using the Kaplan-Meier method. Prognostic factors for CSS and RFS were sought by Cox regression analyses. RESULTS: 106 patients were included. The primary tumors were mostly renal (47.7%) and pulmonary (32.3%). RFS and CSS estimated rates at 5 years were 20.7% and 63.7%, respectively. In univariate analysis, tumor size (HR 3.83; p = 0.04) and the metastasis timing (synchronous vs. metachronous; HR 0.47; p = 0.02) were associated with RFS. In multivariate analysis, tumor size (HR 8.28; p = 0.01) and metastasis timing (HR 18.60; p = 0.002) were significant factors for RFS. In univariate analysis, the renal origin of the primary tumor (HR 0.1; p < 0.001) and the disease-free interval (DFI; HR 0.12; p = 0.02) were associated with better CSS, positive surgical margins with poorer CSS (HR 3.4; p = 0.01). In multivariate analysis, the renal origin of the primary tumor vs. pulmonary (HR 0.13; p = 0.03) and vs. other origins (HR 0.10; p = 00.4) and the DFI (HR 0.01; p = 0.009) were prognostic factors for CSS. CONCLUSION: In this study, tumor size and synchronous occurrence of the adrenal metastasis were associated with poorer RFS. Renal origin of the primary tumor and longer DFI were associated with better CSS. These prognostic factors might help for treatment decision in the management of adrenal metastasis.

[Renal Trauma]. / Traumatismes du rein.

INTRODUCTION: Renal traumas are common, observed in 10% of patients with abdominal trauma. Most renal traumas are blunt, resulting from a direct hit or from an abrupt deceleration. MATERIAL AND METHODS: We realized a synthesis of renal trauma management for nurses. RESULTS: Clinical presentation often encompasses gross hematuria and lumbar pain. The best diagnostic tool is computed tomography (CT) urogram. Based on CT urogram images, renal traumas are classified according to the American Association for the Surgery of Trauma (AAST) classification in five grades of increasing severity. The management is conservative in the vast majority of cases and has been largely simplified over the past few years, being now mostly based on observation. Radiological interventional and endoscopic procedures are used only in very selected cases and surgical exploration has become extremely rare. CONCLUSION: The prognosis has also considerably improved and renal trauma rarely result in death or loss of the kidney nowadays.

Management of renal transplant urolithiasis: a multicentre study by the French Urology Association Transplantation Committee.

PURPOSE: Urolithiasis is rare among renal transplant recipients and its management has not been clearly defined. METHODS: This multicentre retrospective study was organised by the Comité de Transplantation de l'Association Française d'Urologie (French Urology Association transplantation committee). Statistical analysis was performed with SPSS 19 software. RESULTS: Ninety-five patients were included in this study. Renal transplant urolithiasis was an incidental finding in 55% of cases, mostly on a routine follow-up ultrasound examination. One half of symptomatic stones were due to urinary tract infection and the other half were due to an episode of acute renal failure. The initial management following diagnosis of urolithiasis was double J stenting (27%), nephrostomy tube placement (21%), or watchful waiting (52%). Definitive management consisted of: watchful waiting (48%), extracorporeal lithotripsy (13%), rigid or flexible ureteroscopy (26%), percutaneous nephrolithotomy (11%) and surgical pyelotomy (2%). All transplants remained functional following treatment of the stone. The main limitation is the retrospective design. CONCLUSIONS: The incidence of lithiasis could be higher in kidney transplanted patients due to a possible anatomical or metabolical abnormalities. The therapeutic management of renal transplant urolithiasis appears to be comparable to that of native kidney urolithiasis.

Robot-assisted renal transplantation using the retroperitoneal approach (RART) with more than one year follow up: Description of the technique and results.

OBJECTIVES: To describe the technique and report our first experience of robotic-assisted renal transplantation (RART) with more than one year follow up. PATIENTS AND METHODS: In our center the first case of RART was realized in October 2013 with a cadaveric graft. We used the combined extra- and intraperitoneal robot assisted laparoscopic route with extraperitoneal positioning of the graft and intraperitoneal transplantation. The patient was placed in the supine position with arms along the body; the robot came from the right inferior part of the patient. Access to the retroperitoneal space was obtained using an Alexis trocar that permitted the insertion of the kidney with ice without losing the pneumoperitoneum. Ports included a 12-mm camera port (placed under the ombilicus), two 8-mm robotic ports (placed 6cms laterally from the previous port) and a 12-mm assistant port (placed between the upper port and the ombilic). All the pre-, per- and postoperative data were prospectively included in a database. We report the results of the initial experience of RART, performed with more than one year follow-up. RESULTS: This technique is the first described using the retroperitoneal approach that is the routine approach for conventional open renal transplantation. This approach permitted to perform excellent arterial, veinous and ureteral anastomosis. Eight cases of RART were conducted between October 2013 and November 2015 (five men and three women). The average age was 58 years (range 39-75years). The average body mass index was 28 (range 22-38). Five patients had history of abdominal surgery and were dialyzed for 30 months on average (range 3-63months). Three left and five right cadavers kidneys were transplanted in the right iliac fossa. The mean graft size was 109mm (range 90-130). The mean length of the incision for insertion of the graft was 60 mms (40-100mms). Mean warm ischemia time was 63minutes (range 46-84). The total operative time was 200minutes (149-245). No patient was transfused during surgery and two were transfused postoperatively. Median length of hospital stay was 14 days (range 10-30 days). Only one patient needed postoperative morphine, the pain visual analogic scale 12hours postoperatively was 2 (0-5). Mean serum creatinine at seven days, at three months and at one year was 400 (98-639micromol/L), 151 (80-235micromol/L) and 129 (86-194micromol/L) respectively. At one year follow-up, no patient had a wound infection or incisional hernia. One patient was re-operated for ureteral anastomosis stricture. CONCLUSION: The retroperitoneal approach for RART permits the kidney to be cooled and a direct access to the iliac vessels and bladder. This initial series with more than a year of post-monitoring RART shows promising results despite some initial technical difficulties. The procedure can still be improved and hoped to see an improvement in the results. A comparison to the results of the conventional route is necessary before diffusing the robot-assisted technique.

Prostate cancer before renal transplantation: A multicentre study.

INTRODUCTION: The surgical issues of renal transplantation (RT) after localized prostate cancer (PC) treatment and oncological outcomes after transplantation in patients on the waiting list with a history of PC were unknown. We conducted a retrospective multicentre study including all patients with PC diagnosed before the kidney transplantation. METHODS: Fifty-two patients were included from December 1993 to December 2015. The median age at diagnosis of PC was 59.8years old. RESULTS: The median PSA rate at diagnosis was 7ng/mL. Twenty-seven, Twenty-four, and one PC were respectively low, intermediate and high risk according to d'Amico classification. Forty-three patients were treated by radical prostatectomy (RP): 28 retropubic, 15 laparoscopic and 3 by a perineal approach. Eighteen patients had a lymph node dissection. Four patients were treated with external radiotherapy and 2 by brachytherapy. Eight patients underwent radiotherapy after surgery. The median time between PC treatment and RT was 35.7 months. The median operating time for the renal transplantation was 180min (IQR 150-190; min 90-max 310) with a median intraoperative bleeding of 200mL (IQR 100-290; min 50-max 2000). A history of lymphadenectomy did not significantly lengthen operative time (P=0.34). No recurrence of PC was observed after a median follow of 36months. CONCLUSION: PC discovered before RT should be treated with RP to assess the risk of recurrence and decrease waiting for a RT. If the PC is at low risk of recurrence, it seems possible to shorten the waiting time before the RT after a multidisciplinary discussion meeting. LEVEL OF EVIDENCE: 4.

[Impact of learning curve in renal transplantation]. / Impact de la courbe d'apprentissage dans la transplantation rénale.

OBJECTIVES: Renal transplantation is performed only in university hospital centres, in accredited transplanting centres. The aim of this study is to analyse the learning curve of this operation and its impact on the graft survival. PATIENTS-METHODS: Monocentric retrospective study in which 3 groups have been defined: Juniors 1, Juniors 2 and Seniors corresponding respectively to the first thirty transplantations and to the last thirty transplantations of 5 clinical leaders, and 30 transplantation graft of referent seniors. Data have been registered in a database. Operation times, lukewarm ischemic times and postoperative complications have been compared within the 3 groups. RESULTS: A clear difference of operation time has been noted within the 3 groups with an average time of 202 minutes for Juniors 1, 173 minutes for Juniors 2 and 140 minutes for Seniors (P<0.0001). Likewise, concerning lukewarm ischemic time and vascular anastomosis time respectively with an average time of 72, 59 and 40 min (P<0.0001). Vascular complications occurred in 20% of cases in Juniors 1, 44.3% of cases in Juniors 2 and 17% of cases in Seniors (P=0.65). There were no significant differences of survival without urinary complications: 20% of complications for Juniors 1, 10% for Juniors 2 and 17% for Seniors (P=0.63). Similarly results have been obtained with analysing complications following Clavien's order. CONCLUSION: This study reveals that renal transplantations operated by young surgeons require longer operation and lukeward ischemic time but without significant repercussions on the surgical complication rate and the global survival. This stresses on the importance of surgical training during medicine internship.

[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.

[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.

[Comparative analysis of photoselective vaporization of the prostate with the Greenlight laser and open prostatectomy for high volume prostate hypertrophy]. / Analyse comparative coût-efficacité de la photovaporisation prostatique par laser Greenlight et de l'adénomectomie pour hypertrophie de la prostate de gros volume.

PURPOSE: Comparative medical economic study between total prostatectomy and laser in the treatment of benign prostatic hyperplasia in patients whose prostate is more than 80g. MATERIALS AND METHODS: This study compared data registered retrospectively for the group AVH and prospective data for PVP patients. The patients whose prostate weighed more than 80g by echography were selected. The adopted point of view was the one of the hospital and the temporal horizon was of one year after the surgical operation. Direct costs per- and post-surgery were taken into account including specific surgical care and secondary surgical revision. The medical data per- and postoperative were also compared. Primary outcome measure was incremental cost per procedure. RESULTS: Forty-one patients in the AVH group and 53 in the PVP group. The mean length of stay (LOS) is significantly shorter in the PVP group (3.0±1.0 days vs 10.4±4.0; P<0.001). Re-operation rate was significantly lower in the PVP group (1.9% vs 19.5% P<0.001). The cost analysis shows a mean additional cost of 1450 euros for the AVH group. CONCLUSION: PVP was cost-effective because it was more economic and it lead to lower re-operation rate until one year of follow-up than in the AVH group. Nevertheless, these data deserve to be nuanced by unfavorable results of the AVH in comparison with those of the literature.

[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.

Long-term outcomes of 80-watt KTP and 120-watt HPS GreenLight photoselective vaporization of the prostate.

OBJECTIVE: Photoselective vaporization of the prostate (PVP) is becoming a surgical treatment alternative of transurethral resection of the prostate for male lower urinary tract symptoms (LUTS) secondary to benign prostatic obstruction (BPO). We evaluated the outcome and postoperative complications of PVP performed by 80-W KTP and 120-W HPS GreenLight lasers (AMS®) over a 4-year period. MATERIALS AND METHODS: This is a prospective monocentric study that included all patients who underwent PVP. They had routine follow-up at 1 month, 3 months, 6 months and every year until the fourth postoperative year. Listed data were maximum urinary flow rate (Qmax), International Prostate Symptom Score (IPSS), post-void residual (PVR) volume, prostate-specific antigen (PSA) and prostate volume. We collected the postoperative complications. RESULTS: From September 2005 to May 2008, 77 patients out of a 409 patients cohort underwent surgery and were followed during 4 years. At 4 years mean Qmax increase was 82.5%; mean IPSS, PVR volume, PSA and prostate volume decreases were 79.1, 69.8, 43.8 and 22.9%, respectively. The main side effects observed were storage LUTS. A urinary catheter was replaced after a first withdrawal failure in 10 patients (15.6%) after surgery. CONCLUSIONS: PVP showed a sustainable efficacy and an appealing tolerance profile during a 4-year period in patients with LUTS secondary to BPO.

[A majority of useless call of an on-call urology resident: a study of the AFUF]. / Une majorité d'appels évitables au cours des astreintes d'urologie en CHU : l'étude de l'AFUF.

GOAL: To assess the workload of an on-call urology resident at a French University Hospital. MATERIAL: A prospective study was performed during 15 days in February 2012. The data recorded in our database regarded the resident (sex, age, time to go to work), the call (emergency, type and reason) and the person who called (grade, department). RESULTS: Seven centres including 18 residents participated. On average five calls were received per day [0-17]. After midnight, the resident was called less than twice (1.6). There was an actual emergency in 64% of cases [0-13]. The urology-related call motives (73%) mainly consisted in acute urine retention (AUR) and catheter problems (73), renal colic (RC) (49), acute pyelonephritis (23), and hematuria (22). Residents had to go to the hospital in 55% of AUR and catheter problems, 30% of acute pyelonephritis, 17% of RC and 14% of hematuria. The emergency department (ED) called the urology resident in 39% of cases but only 18% required the presence of the resident. A call made by a senior was more likely to be an emergency (67%) than by a resident or a nurse (51%, P=0.02). CONCLUSION: The urology resident when on-call is mainly asked for an advice by the ED. Among urology-related advice, bladder catheterization problems were the most frequent. RC was the second call motive but most of the time was not an actual emergency.
