Miniaturized percutaneous nephrolithotomy versus retrograde intrarenal surgery in the treatment of lower pole renal stones.

OBJECTIVES: Miniaturization of percutaneous nephrolithotomy techniques have led to their increased consideration for lower pole renal stones that can prove more challenging to reach using retrograde intrarenal surgery. The objectives of the present study were to evaluate and compare the outcomes of miniaturized percutaneous nephrolithotomy (miniPCNL) and retrograde intrarenal surgery (RIRS) for the treatment of lower pole renal stones. MATERIALS AND METHODS: A retrospective study was performed in two academic urology departments between January 2016 and June 2019. Patients presenting with one or multiple stones of the lower calyx and/or renal pelvis, between 10 and 40mm based on CT-scan treated by miniPCNL or RIRS were included. RESULTS: In all, 115 miniPCNL and 118 RIRS procedures were included. The rate of patients with no significant residual fragment (stone free rate) after the first procedure was higher in the miniPCNL group (69% vs. 52% P=0.01), especially for stones>20mm (63% vs. 24% respectively, P<0.001) and stones with a density≥1000HU (69% vs. 42% respectively, P=0.009). The higher stone free rate of miniPCNL was confirmed in multivariate analysis, adjusting for stone size and number of stones, OR 4.02 (95% CI 2.08-8.11, P<0.0001). The overall postoperative complication rate was higher in the miniPCNL group than in the RIRS group (23% vs. 11%, P=0.01). A second intervention for the treatment of residual fragments was necessary for 9.6% of patients in the miniPCNL group versus 30.5% of patients in the RIRS group (P<0.001). Pre-stenting rate and duration of ureteral drainage (2 [1-8] vs. 25 days [7-37], P<0.001) were lower in the miniPCNL group. CONCLUSIONS: The stone free rate was higher after miniPCNL, especially for stones>20mm and with a density>1000 HU, but was associated with a higher risk of postoperative complications and a longer hospital stay. RIRS resulted in fewer complications at the cost of a higher retreatment rate and longer ureteral stenting. LEVEL OF EVIDENCE: 3.

One-year Functional Outcomes after Holmium Laser Enucleation of the Prostate (HoLEP): Introduction of a Composite Score (Hexafecta).

OBJECTIVE: To compare the efficiency (micturition symptoms, continence, erection) and safety of Holmium Laser Enucleation of the Prostate (HoLEP) with a single composite score (the Hexafecta score) one year postprocedure. PATIENTS AND METHODS: We conducted a single-center retrospective study including all patients who had undergone HoLEP for the treatment of benign prostate hyperplasia (BPH) between May 2013 and August 2017. Data were obtained preoperatively and at the 6- and 12-month visits. We also reported all 90-day complications. The Hexafecta score included 6 criteria: peak urine flow of at least 15ml/s, 30% reduction in International Prostate Symptoms Score (IPSS) score, quality of life via the IPSS less than 2, no incontinence (International Consultation Incontinence Questionnaire), no significant change in erectile function (International Index of Erectile Function), and no grade III or more complications according to the Clavien-Dindo classification. RESULTS: Two hundred thirty-five patients were included, of whom 197 (83.8%) completed the 12-month visit. Complete data were available to assess the Hexafecta score for 178 of them (75.7%). Most of the missing data were for uroflowmetry and the erectile function assessment. Hundred three patients (58%) met all 6 criteria, while 45 (25%) met 5 of them. None were retreated for BPH in the follow-up period. The de novo incontinence rate was 4.1%. CONCLUSION: The Hexafecta score is a simple, transversal method for comprehensively evaluating functional outcomes after HoLEP surgery. Such an evaluation could be used to compare other types of procedures for BPH treatment. LEVEL OF EVIDENCE: 3.

Residents and patients benefit from surgical simulation on a live porcine model, could we consider it as ethical?

INTRODUCTION: The objective was to evaluate, by self-questionnaire, the feeling of participants in surgical training sessions on a live porcine model. METHODS: A computerized questionnaire (GoogleForm ©) was sent to the members of the French Association of Urologists-in-Training (AFUF) (fellows and residents). Only questionnaires from Urologists-in-training who had participated in surgical training sessions were included. The sessions consisted of performing surgeries such as laparoscopic nephrectomies or laparoscopic cystectomies. RESULTS: Overall, 198 met the inclusion criteria. A total of 36.4% (72/198) of the participants were fellows and 63.6% (126/198) were residents. According to the participants, the main interest of sessions was to be able to train for emergency situations. A total of 79.8% (158/198) of the participants wanted surgical simulation to become compulsory. To their opinion, the main advantage of surgical simulation on a live porcine model was: technical progress in 87.4% (173/198) of cases. A total of 13.1% (26/198) of the participants found it was unethical to perform the first technical procedures on live animal models. A total of 65.7% (130/198) of the participants considered that there is currently no system of substitution. CONCLUSION: For the participants, surgical training on a live porcine model allows technical progress while training for serious emergency situations. Surgeons and patients could benefit from this risk-free mock surgical scenario. LEVEL OF EVIDENCE: 3.

Educational program in onco-urology for young urologists: What are their needs?

PURPOSE: The emergence of new communication media such as digital contents are progressively replacing more traditional medias in the field of educational programs. Our purpose was to assess urologist in training aspirations regarding urological education. METHODS: Members of a national urologist in training association were sent an anonymous online questionnaire regarding their medical formation in the field of urology. Responders interest for urological sub-specialty or education support (new tools and traditional support) were evaluated through a 5-point Likert scale. RESULTS: Overall, 109 young urologists (26%) responded to the survey. Most of the respondents worked during their training in an academic hospital (n=89, 82%). The three favorite tools for training chosen by the responders were: videos, workshop or masterclass, and podcasts (responders very interested were respectively n=64 (58.7%), n=50 (45.9%), and n=49 (45%)). E-mail newsletters were reported as the less useful educational tool by participants (n=38, 34.9%). Participants were very interested in improving their surgical skills and their radiological knowledge. Responders who were the most attracted by PCa were much more looking to improve their systemic treatment and radiological knowledges. CONCLUSIONS: Urologic-oncology was a priority regarding education for urologists in training. A majority of participants expressed a lack in their surgical education, revealing a reduced OR access and underlining utilization of new tools such as simulation. New digital contents such as social media or podcast achieved high interest for the participants, instead of more traditional media. There is a need that educational content evolve and uses new digital media. LEVEL OF EVIDENCE: 3.

Management of long ureteral stenosis: Alternatives to indwelling ureteral stents.

OBJECTIF: Evaluate kidney autotransplantation (KAT) and ileal ureter substitution (IUS) practice and outcome as alternatives to indwelling ureteral stents for the management of long ureteral stenosis (US). MATERIAL: We included all patients treated for US with KAT or IUS in 5 French university urology centers between 2010 and 2018. We excluded US due to urothelial carcinoma. Primary endpoint was the preservation of ipsilateral kidney and renal function without any urinary diversion. RESULTS: 22 patients were treated with KAT (n=8, 36.4%) and IUS (n=14, 63.6%). Mean US length was 4.6cm and 6cm (P=0.52) in KAT and IUS groups respectively. US etiologies were lithiasis, iatrogenic, retroperitoneal fibrosis or extrinsic compression. US level was varied. The surgery was described as difficult because of peritoneal adhesions or major peri-ureteral fibrosis. Mean operating time and hospital stay were 336 and 346minutes (P=0.87) and 8 and 15 days respectively (P=0.001). Postoperative complications were mostly Clavien ≤2 (n=17, 77.3%). Revision surgery was required in the KAT group in 3 cases (37.5%), for textiles, renal vein thrombosis and anastomotic leak, none in the IUS group. The mean follow-up was 15.7 months. All but one (in the KAT group) ipsilateral kidneys were preserved, without renal function impairment (Δcreat +2.1 vs. +2.4µmol/l respectively, P=0.67), nor urinary diversion. CONCLUSION: KAT and IUS are safe alternatives whose indication depends on surgeons expertise. Our study pointed out the scarcity of this practice suggesting the need to refer patients to expert centers. LEVEL OF EVIDENCE: 3.

[Use of antiplatelet therapy and direct oral anticoagulants in candidates for renal transplantation: The French guidelines from the CTAFU]. / Recommandations françaises du Comité de transplantation de l'association française d'urologie (CTAFU) : agents antiplaquettaires et anticoagulants oraux directs en transplantation rénale.

OBJECTIVE: To define guidelines for the use of antiplatelet therapy (AT) and direct oral anticoagulants (DOAC) in candidates for kidney allotransplantation. METHOD: A review of the medical literature following a systematic approach was conducted by the CTAFU to report the use of AT and DOAC before major surgery and in the setting of advanced chronic kidney disease, defining their managment prior to kidney transplantation with the corresponding level of evidence. RESULTS: DOAC are not recommended in patients under dialysis. Aspirin therapy, but not anti-P2Y12 and DOAC, may be maintained during renal transplantation. Anti-P2Y12 and DOAC should not be use in patients awaiting a kidney transplant, except when a living donor is scheduled, therefore authorizing treatment interruption in optimal conditions. Further data regarding DOAC reversion and monitoring may improve their use in this setting. Global level of evidence is weak. CONCLUSION: These French recommendations should contribute to improve surgical management of kidney transplant candidates exposed to AT or DOA.

[Localized Prostate cancer in candidates for renal transplantation and recipients of a kidney transplant: The French Guidelines from CTAFU]. / Recommandations françaises du Comité de transplantation de l'Association française d'urologie (CTAFU) : cancer de la prostate localisé chez le patient transplanté rénal ou en attente de transplantation.

OBJECTIVE: To define guidelines for the management of localized prostate cancer (PCa) in kidney transplant (KTx) candidates and recipients. METHOD: A systematic review (Medline) of the literature was conducted by the CTAFU to report prostate cancer epidemiology, screening, diagnosis and management in KTx candidates and recipients with the corresponding level of evidence. RESULTS: KTx recipients are at similar risk for PCa as general population. Thus, PCa screening in this setting is defined according to global French guidelines from CCAFU. Systematic screening is proposed in candidates for renal transplant over 50 y-o. PCa diagnosis is based on prostate biopsies performed after multiparametric MRI and preventive antibiotics. CCAFU guidelines remain applicable for PCa treatment in KTx recipients with some specificities, especially regarding lymph nodes management. Treatment options in candidates for KTx need to integrate waiting time and access to transplantation. Current data allows the CTAFU to propose mandatory waiting times after PCa treatment in KTx candidates with a weak level of evidence. CONCLUSION: These French recommendations should contribute to improve PCa management in KTx recipients and candidates, integrating oncological objectives with access to transplantation.

[Living donor nephrectomy: The French guidelines from CTAFU]. / Recommandations françaises du Comité de transplantation de l'Association française d'urologie (CTAFU) : néphrectomie pour don de rein.

OBJECTIVE: To propose surgical recommendations for living donor nephrectomy. METHOD: Following a systematic approach, a review of the literature (Medline) was conducted by the CTAFU regarding functional and anatomical assessment of kidney donors, including which side the kidney should be harvested from. Distinct surgical techniques and approaches were evaluated. References were considered with a predefined process to propose recommendations with the corresponding levels of evidence. RESULTS: The recommendations clarify the legal and regulatory framework for kidney donation in France. A rigorous assessment of the donor is one of the essential prerequisites for donor safety. The impact of nephrectomy on kidney function needs to be anticipated. In case of modal vascularization of both kidneys without a relative difference in function or urologic abnormality, removal of the left kidney is the preferred choice to favor a longer vein. Mini-invasive approaches for nephrectomy provide faster donor recovery, less donor pain and shorter hospital stay than open surgery. CONCLUSION: These French recommendations must contribute to improving surgical management of candidates for kidney donation.

[Urinary stones in renal transplant recipients and donors: The French guidelines from CTAFU]. / Recommandations françaises du Comité de transplantation de l'association française d'urologie (CTAFU) : lithiase urinaire chez le receveur ou le donneur en transplantation rénale.

OBJECTIVE: To define guidelines for the management of kidney stones in kidney transplant (KTx) donor or recipients. METHOD: Following a systematic approach, a review of the literature (Medline) was conducted by the CTAFU to report kidney stone epidemiology, diagnosis and management in KTx donors and recipients with the corresponding level of evidence. RESULTS: Prevalence of kidney stones in deceased donor is unknown but reaches 9.3% in living donors in industrialized countries. Except in Maastrich 2 donors, diagnosis is done on systematic pre-donation CT scan according to standard french procedure. No prospective study has compared therapeutic strategies available for the management of kidney stones in KTx donor: ureteroscopy or an extra corporeal lithotripsy in case of living donor prior to donation, ex vivo approach (pyelotomy or ureteroscopy), ureterocopy in the KTx recipient or surveillance. De novo kidney stones result from a lithogenesis process to be identified and treated in order to avoid recurrences. The context of solitary functional kidney renders the prevention of recurrence of great importance. Diagnosis is suspected when identification of a renal graft dysfunction, hematuria or urinary tract infection with renal pelvis dilatation. Stone size and location are determined by computed tomography. There are no prospective, controlled studies on kidney stone management in the KTx. The therapeutic strategies are similar to standard management in general population. CONCLUSION: These French recommendations should contribute to improve kidney stones management in KTx donor and recipients.

COVID19 pandemic impacts on anxiety of French urologist in training: Outcomes from a national survey.

INTRODUCTION: The COVID-19 outbreak in France is disturbing our health system. Urologists in training who are already known to have burnout, are in the front line to face this disease. The aim of our study was to assess the psychological impact of COVID-19 pandemic on young French urologists in training. MATERIAL AND METHODS: A self-administered anonymous questionnaire evaluating the pandemic added stress, and its negative impact on work and training quality, was e-mailed to the members of the French Association of Urologists in Training (AFUF). The association includes all French junior and senior residents. The survey lasted 3 days. Multivariable analyses using logistic regression was performed to identify the predictive factors. RESULTS: Two hundred and seventy-five (55.5%) of the 495 AFUF members responded to the questionnaire. More than 90% of responders felt more stressed by the pandemic. Fellows and senior residents were more likely to feel that the crisis had an important impact on their work quality (OR=1.76, IC95=[1.01-3.13]), even more when COVID 19 patients were present in their department (OR=2.31, IC95=[1.20-4.65]). Past medical history of respiratory disease (OR=2.57, IC95=[1.31-5.98]) and taking in charge COVID19 patients (OR=1.85, IC95=[0.98-3.59]) were additional risk factors. CONCLUSION: COVID19 pandemic has a negative impact on young French urologists in training and on their work and training quality. Managing their psychosocial well-being during this time is as important as managing their physical health. LEVEL OF EVIDENCE: 3.

[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.

[Focal HIFU vs robot-assisted total prostatectomy: Functionnal and oncologic outcomes at one year]. / Traitement focal par HIFU versus prostatectomie radicale robot-assistée pour cancer de la prostate localisé : résultats carcinologiques et fonctionnels à 1 an.

OBJECTIVE: To analyse the functional and oncologic outcomes at one year of focal therapy with HIFU compared with total prostatectomy in patients with localised prostate cancer (PCa). PATIENTS AND METHODS: Retrospective and monocentric study from 2008 to 2014 comparing 2 cohorts of patients with localised PCa (T1/T2 clinical stage, Gleason score≤3+4=7 and PSA<15ng/mL), one treated by focal therapy (HIFU-F group), one by robot-assisted total prostatectomy (RATP group). Primary outcome was a trifecta defined as: absence of urinary incontinence, erectile function with sexual relations without treatment, negative PSA with negative surgical margins (RATP group) or negative biopsy cores (HIFU-F group). RESULTS: The 53 patients included in the "HIFU-F" group and the 66 patients in the "RATP" group were similar in terms of preoperative PSA, D'Amico risk group, erectile function but were different in terms of age, prostatic volume, length of cancer, Gleason score. Complication rate was not different. In multivariate analyse with propensity score, "HIFU-F" group achieved a better trifecta score than "RATP" group (OR=8,3, p=0,005). CONCLUSION: In case of low or intermediate risk localised PCa, "HIFU-F" group had better functional outcomes than initial learning curse "RATP" group, at one year. A long-term evaluation by a common endpoint is necessary to judge the oncological equivalence of both techniques. LEVEL OF EVIDENCE: 3.

[Simultaneous pancreas and kidney transplantation]. / Transplantation simultanée de rein et de pancréas.

OBJECTIVES: To perform a State of The Art about the different aspects of pancreas transplantation such as indications, technical features, immunosuppressive strategies and outcomes of simultaneous pancreas-kidney transplantation. MATERIAL AND METHODS: An exhaustive systematic review of the scientific literature was performed in the Medline database (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) using different associations of the following keywords (MESH) : « pancreas transplantation; kidney transplantation; simultaneous pancreas-kidney transplantation; immunosuppression ¼. Publications obtained were selected based on methodology, language, date of publication (last 20 years) and relevance. Prospective and retrospective studies, in English or French, review articles; meta-analysis and guidelines were selected and analyzed. This search found 2736 articles. After reading titles and abstracts, 23 were included in the text, based on their relevance. RESULTS: These last few years, considerable progresses were done in optimizing indication for pancreas transplantation, as well as surgical improvement and a better used of immunosuppression. In the first part of this article, demographics, indication and pre-transplant evaluation will be described. The different techniques of procurement, preparation and transplantation will then be discussed. Finally, the results and outcomes of pancreas transplantation will be reported. CONCLUSIONS: Despite its morbidity, pancreas transplantation is the optimal treatment of end stage renal disease in diabetic patients under 55. Long-term results and quality of life improvement after pancreas transplantation are excellent. LEVEL OF EVIDENCE: NA.

[Pediatric kidney transplantation]. / Transplantation rénale pédiatrique.

AIMS: To describe indications, surgical aspects, results and outcomes of kidney transplantation in children. MATERIAL AND METHODS: An exhaustive systematic review of the scientific literature was performed in the Medline database (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) using different associations of the following keywords (MESH): "kidney transplantation", "pediatric", "children", "outcomes". Publications obtained were selected based on methodology, language, date of publication (last 10 years) and relevance. Prospective and retrospective studies, in English or French, review articles; meta-analysis and guidelines were selected and analyzed. This search found 2608 articles. After reading titles and abstracts, 18 were included in the text based on their relevance. RESULTS: Kidney transplantation is the gold-standard treatment for end stage renal kidney disease in children. The surgical procedure is well standardized with a retroperitoneal approach when child and kidney size allow it or a transperitoneal approach in child less than 15 kg and big size kidney graft. Anastomosis sites include iliac vessels in the retroperitoneal approach, and inferior vena cava and aorta in case of transperitoneal procedure. Ureteral reimplantation used most of the time a Campos Freire technique. Sometimes, particular conditions in the recipient (such as vena cava thrombosis) required procedure adaptation. CONCLUSION: Graft survival dramatically increased over the past few years and is now superior to those observed in adult kidney transplantation, particularly in experienced team with microsurgery skills. Immunosuppressive treatments are similar to adults. Viral infections and post-transplant lymphoproliferative disorder are the main complications of renal transplantation in children and may lead to lethal outcomes. An increase graft loss is observed during boyhood due to immunosuppressive drugs uncompliance.

[Ischemia-reperfusion. Preservation solution and hypothermic machine perfusion]. / Ischémie­reperfusion. Liquides de conservation et machines de perfusion en transplantation rénale.

AIMS: To describe ischemia-reperfusion mechanisms, the impact on kidney graft and strategies developed to minimize ischemia-reperfusion damages. MATERIAL AND METHODS: An exhaustive systematic review of the scientific literature was performed in the Medline database (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) using different associations of the following keywords: ischemia-reperfusion; organ preservation; hypothermic machine perfusion; renal transplantation. Publications obtained were selected based on methodology, language, date of publication and relevance. Prospective and retrospective studies, in English or French, review articles; meta-analysis and guidelines were selected and analyzed. This search found 1293 articles. After reading titles and abstracts, 88 were included in the text, based on their relevance. RESULTS: Ischemia-reperfusion injuries occur when blood supply of an organ is interrupted or drastically reduced. Ischemic damages started immediately after arterial clamping in donor, persist during cold ischemia time, and are increased after reperfusion because of increased oxygen levels, organ warming and recipient cell infiltration. Besides metabolic and biologic impact, IR induced dramatic immunologic impact through immunologic cells activation. CONCLUSIONS: Knowledge of IR mechanisms is crucial to improve organ storage strategies and to decreased impact of IR on long-term graft and patient survival. Hypothermic machine perfusion was associated with prolonged graft survival versus cold storage. Principles and results of hypothermic machine perfusion will be reported.

INTRODUCTION: The temporary prosthetic sphincterotomy is a possible treatment for neurologic detrusor sphincter dyssynergia (DSD). The purpose of the study was to verify the feasibility and effectiveness of the urethral stent (US) Temporary ALLIUM BUS "BULBAR URETHRAL STENT". PATIENTS AND METHODS: A prospective, non-comparative, single-center starting in 2015 was conducted. Were included patients over 18 years, with a neurologic DSD proved urodynamically for which medical treatment was not indicated or failed. The primary endpoint was the percentage of patients who had a voiding method considered as improved or much improved at 1 month and the feasibility of the procedure. RESULTS: From January to June 2015, 7 patients, (mean age 47.9 years [24-76 years]) were prospectively enrolled. One patient was lost to sight at one month and therefore excluded. The median follow-up was 8.1 months (1-10 months). All procedures were technically successful. At 1 month, there were 57% of grade 2 complications (Clavien-Dindo), 1 of 6 patients had a migration of the US. At one month, quality of life and the urologic situation was considered good in 3 patients, unchanged in 2 patients and decreased in 1 patient. The study was stopped after the inclusion of seven patients. At the date of the latest news, 5 of 6 patients had a migrated or an explanted US. CONCLUSION: The temporary urethral stent ALLIUM BUS does not seem to be a possible surgical alternative for the treatment of detrusor sphincter dyssynergia. LEVEL OF EVIDENCE: 4.

[The W-shaped ileal neobladder: Long term functional outcomes and health-related quality of life]. / La néovessie iléale en W : résultats fonctionnels et qualité de vie à long terme.

PURPOSE: To evaluate functional outcomes and patients' health-related quality of life over ten years after a W-shaped ileal neobladder urinary diversion. PATIENTS AND METHODS: From 1994 to 2004, 87 patients with bladder cancer underwent a cystoprostatectomy with a W-shaped ileal neobladder. Among them, 31 patients (35.6%) were evaluated. The average follow-up was 158months, average age was 72years. We assessed functional outcomes (use of protections, USP score, uroflowmetry, postvoid residual volume), overall health-related quality of life (SF-36 score), and specific urinary-related quality of life (Ditrovie scale). RESULTS: Daytime continence was satisfactory in 29 patients (96.8%). Night-time continence was satisfactory in 27 patients (87.1%). Mean daytime continence, hyperactivity and dysuria scores of the USP were respectively 1.5/9, 3.2/21 and 2/9. Mean value of the maximum flow rate was 18mL/s for an average voiding volume of 324mL and an average postvoid residual volume of 70mL. The 8 dimensions of the SF-36 were all comparable with the French population's values. According to the Ditrovie scale whose average value was 1.83, the health-related quality of life was unchanged or little changed by urinary disorders in 28 patients (90.3%). CONCLUSIONS: Our results suggest that voiding status and health-related quality of life remain satisfactory over ten years after an orthotopic ileal neobladder derivation. LEVEL OF EVIDENCE: 5.

[French resident's performance on laparoscopic surgery box trainer: 7-year results of pelvitrainer contests]. / Performance des internes français sur simulateur de chirurgie laparoscopique : les résultats de 7 ans d'olympiades du pelvitrainer.

OBJECTIVES: The study objectives were to analyze the resident's laparoscopic surgery performance in order to build a self-assessment data set, to identify discriminatory exercises and to investigate the suturing time changes. METHODS: From 2007 to 2014, the French Association of Urologist in Training (AFUF) organized 7 pelvitrainer contests. Participant scores on 11 laparoscopic surgery exercises were evaluated. RESULTS: Sixty-six residents participated to these contests and performed 11 exercises each. Twenty-two (33.3 %) participants were beginners, 26 (39.4 %) intermediates et 18 (27.3 %) experienced. The participant scores were gathered into a data set including the average time per exercise. We found a time scoring improvement related to the resident experience for all exercises. A significant decline in time was noted for exercise 8 and 9 between beginners and intermediates (139s [±71]), (173.9s [±118.3]) and between beginners and experienced (80.6s [±26.7]), (94,1s [±42.7]) with a P<0.05. The correlation coefficient for the exercise 11 duration (vesico-uretral anastomosis) was 0.04 over a 7-year period (P=0.44). CONCLUSION: The study provided a data set on 11 laparoscopic surgery tasks which can be consulted by all residents as a reference in a self-assessment process. Two exercises (8 and 9) discriminated beginners from intermediates and experienced groups and could be used as a benchmark ahead of an operating room procedure. The vesico-uretral anastomosis duration (exercise 11) did not improve significantly between 2006 and 2014. LEVEL OF EVIDENCE: 4.

[Millin adenomectomy in the era of laser enucleation: results in a series of 240 cases]. / L'adénomectomie selon Millin à l'heure de l'énucléation laser : résultats d'une série de 240 cas.

INTRODUCTION: New techniques have been proposed for the surgical treatment of benign prostatic hypertrophy (BPH): laser enucleation and laparoscopic adenomectomy. The objective of this retrospective study was the comparison of the results of Millin adenomectomy realized under contemporary medical conditions, with the results of laser enucleation and laparoscopic adenomectomy. METHOD: Two hundred and forty consecutive Millin adenomectomy cases performed between January 2004 and December 2008 were analyzed. Patient evaluation before operation consisted in IPSS score, quality of life score, maximum flow rate (Qmax), post-void residual volume (PRV), total prostate volume (TPV) performed under trans-rectal ultrasound. Operation duration, adenoma weight, blood loss during operation, transfusion rate, duration of Foley catheterization, duration of hospital stay, and immediate postoperative complications according to Clavien classification were reported. Each patient was systematically controlled at 3 months and was invited by mail for a second control in 2012. Each of the two outpatient controls consisted in the realization of an IPSS, quality of life score, Qmax and PRV. Our results were compared to contemporary results published concerning open adenomectomy and new techniques of adenomectomy. RESULTS: Mean age was 69 years, TPV before operation 111 cc, adenomectomy specimen weight 82 gr, blood loss during operation 246 mL, transfusion rate 6 %, operation duration 88 min, Foley catheterization duration 3.8 days, mean hospital stay 5.6 days. Clinical results at 3 months were: IPSS decrease from 25 to 5 points, quality of life score decrease from 5 to 0.7 points, Qmax increase from 6.5 to 22 mL/sec, PRV decrease from 115 to 7.5 mL. According to the use of either the classical classification or of Clavien classification, the rate of early complications varied respectively from 36 to 49 %. No Clavien grade 4 or 5 complication was observed. Long-term results in 137 (57 %) of the patients with a mean age of 80 years, 5 years medial control (4; 8) after adenomectomy showed an IPSS varying from 2.5 to 6.6 points according to follow-up length, quality of life score varying from 0 to 1.2 points, Qmax varying from 13 to 23 mL/sec, PRV varying from 0 to 25 mL. CONCLUSION: The lack of exhaustivity of the results and the absence of use of Clavien classification rendered difficult any comparison between the different techniques. Urologist motivation in favor of a given technique represented a bias difficult to bypass, even with the realization of a randomized study comparing two techniques. Today, Millin operation still represented the gold standard for the evaluation of new techniques in the surgical treatment of large volume BPH. LEVEL OF EVIDENCE: 5.
