Quality of life of patients treated for kidney stones 10-20mm in diameter in terms of the type of operation performed: A qualitative study.

INTRODUCTION: Urolithiasis is a common chronic disease whose effect on patients' quality of life (QOL) is considerable but depends on the treatment received, differing between types of surgery. Intrarenal stones can be treated with different techniques: extracorporeal shock wave lithotripsy (ESWL), flexible ureteroscopy (fURS), and mini percutaneous nephrolithotomy (mini-PCNL), with proportional success and complication rates. The aim of this study was to qualitatively explore the impact of the different techniques on patients' QOL and understand their experiences of treatment choices. METHODS: Patients treated for medium-sized kidney stones (10-20mm in diameter) were interviewed in a semi-structured manner. The interview data were transcribed and analyzed by theme according to consolidated criteria for reporting qualitative research (COREQ) guidelines. RESULTS: Data saturation was achieved after interviewing 15 patients. The mean interview time was 34min (standard deviation (SD), 6.8min). The mean patient age was 54 years (SD, 9.5 years). Eight patients underwent ESWL, 10 were treated with fURS, and 8 underwent mini-PCNL. Twenty-seven subthemes were coded and regrouped into eight major themes, namely: no sense of choice in the decision-making process for eleven patients; extremely negative experiences of double-J stents for fourteen patients; concern about the risk of recurrence or treatment failure for thirteen patients; complicated hygiene and dietary recommendations for nine patients; technique-dependent postoperative outcomes; relatively well-tolerated operations for thirteen patients; a poor experience of sick leave, often because of a double-J stent; different views regarding future operations. In fact, a third of patients would choose the most effective treatment, a third would choose the simplest procedure and the last third would trust their urologist. Patients' experiences of these operations are variable. CONCLUSION: Urologists must support their patients by presenting the different treatment options with clear, appropriate, and unbiased information. This should ensure patients take part in treatment decisions as part of a personalized treatment plan.

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.

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.

[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.

[Renal cell carcinoma 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) : carcinome rénal sur reins natifs chez le patient transplanté rénal ou en attente de transplantation.

OBJECTIVE: To define guidelines for the management of renal cell carcinoma of the native kidney (NKRCC) in kidney transplant (KTx) recipients and renal cell carcinoma (RCC) in end-stage renal disease (ESRD) patients candidates for renal transplantation. METHOD: A review of the literature following a systematic approach (Medline) was conducted by the CTAFU to report renal cell carcinoma epidemiology, screening, diagnosis and management in KTx candidates and recipients. References were assessed according to a predefined process to propose recommendations with the corresponding levels of evidence. RESULTS: ESRD patients are at higher risk of RCC with a standardized incidence ratio of approximately 4,5 as compared with general population. NKRCC tumors occur in 1 to 3 % of KTx recipients with a 10 to 15-fold increased risk as compared with general population, especially in patients with acquired multicystic kidney disease. Most authors suggest yearly monitoring of the native kidneys using ultrasound imaging. Radical nephrectomy (either open or laparoscopic approach) is the preferred treatment of NKRCC in KTx recipients and RCC in ESRD. Surveillance in a valid option in small or cystic renal masses. In the localized setting, change in immunosuppressive therapy is not recommended besides perioperative avoidance of mTOR inhibitor to limit morbidity. CTAFU does not recommend a mandatory waiting time after nephrectomy for RCC in ESRD patients candidates for renal tranplantation when tumor stage

[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.

[Evaluation of spinal anesthesia in urological outpatient surgery, comparison between two local anesthetics (Chloroprocaine/Bupivacaine)]. / Évaluation de la rachianesthésie en chirurgie ambulatoire urologique, comparaison entre deux anesthésiques locaux (Chloroprocaïne/Bupivacaïne).

INTRODUCTION: Spinal anesthesia in outpatient urology is controversial (longer hospital stay, risk of urinary retention). The main goal was to evaluate outpatient spinal anesthesia and to compare 2 local anesthetics secondarily. MATERIAL: Monocentric retrospective study including all patients undergoing surgery in urological ambulatory surgery under spinal anesthesia between December 2011 and May 2015, split into two groups according to the local anesthetic used: bupivacaine (BP) and chloroprocaine (CP). Quantitative variables were compared by Student's t-test, qualitative variables by χ2 test. RESULTS: Seventy-one (95%) out of the 75 patients included have been discharged the same day. Discharge was impossible in these cases: patient alone at home (1), bladder clot (1), JJ intolerance (1), delayed micturition (1). The mean duration of the procedure was 27±19min, the SSPI's was 55±31min, the stay's was 360±91min. A total of 45 patients (60%) received BP and 30 (40%) received CP. The mean residence time in SSPI was significantly reduced in the CP group (47±24min vs. 61±34min, P=0.04). One patient experienced urination delay in the BP group with no significant difference. No significant difference for the other criteria studied despite the mean age, which is higher in the CP group (P=0.02). CONCLUSION: Spinal anesthesia is adapted to ambulatory urology, and does not increase the risk of urinary retention, especially with CP that would decrease the length of stay in SSPI compared to BP.

[Renal transplantation on vascular prosthesis]. / Transplantation rénale sur prothèse vasculaire.

INTRODUCTION: In front of a very calcified aortoiliac axis, renal transplantation with implantation of the artery on vascular prosthesis can be proposed. This rare intervention is considered difficult and morbid. The main objective of this work was to evaluate the overall and specific survival of the transplant in this situation. The secondary objective was the study of the complications and the evolution of the transplant's renal function. MATERIAL AND METHODS: From a multicenter retrospective data collection of the DIVAT cohort (6 centers) added with data from 4 other transplant centers, we studied transplants with prosthetic arterial anastomosis. RESULTS: Thirty four patients was included. The median duration of follow-up was 2.5 years. 4 patients died in the month following transplantation, 16 were hemodialysis and 9 were transfused. The median survival of the transplant was 212 days. Functional arrests of the transplant were mostly associated with nephrological degradation and return to dialysis (about 80%) while 10% were related to a death of the recipient directly attributable to renal transplantation. The surgical complications of the transplantation were marked by one arterial stenosis, one fistula and 4 urinary stenoses. CONCLUSION: Thus, renal transplantation with arterial anastomosis on vascular prosthesis, on selected patients, offers an alternative to dialysis. A national compendium of transplanted patients on vascular prosthesis would allow a long-term follow-up of transplant's survival and define selection criteria prior to this kind of surgery.

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.

[Anticoagulation impact on bleeding risk during HoLEP: Monocentric study of 156 patients]. / Impact des anticoagulants sur le risque hémorragique au cours de l'HoLEP : étude monocentrique de 156 patients.

OBJECTIVE: Compare the length of hospital stay and the complications after HoLEP between three groups of patients: a control group, a group with antiplatelet therapy, a group with anticoagulation therapy. MATERIALS: Retrospective cohort study that included all consecutive patients who underwent HoLEP for prostatic hyperplasia in our center from may 2013 to may 2016. Anticoagulated patients and patients under clopidogrel had respectively a relay with heparine and aspirine. Patients were seen after surgery at 1 and 3 months. RESULTS: A hundred and fifty six patients were analysed, mean age was 70.7 years (DS 6.8), mean prostate volume 88.8g (DS 34.1). 106 patients were in the control group, 34 had antiplatelet therapy and 16 had anticoagulation therapy. There were no difference between the 3 groups for mean age, mean prostatic volume, PSA. There was also no difference for length of intervention, irrigated volume and length of morcellation between the three groups. There were no difference between patients in the control group and patients with antiplatelet therapy for length of hospital stay (2.1 days vs 2.0 days), lenght of urethral catheterization (1.6 days vs 1.5 days). There was a statistical difference between patients in the control group and patients with anticoagulation therapy for lenght of hospital stay (2.0 days vs 4.4 days; P=0.01), length of bladder irrigation (0.9 day vs 1.8 days; P=0.01), lenght of urethral catheterization (1.6 days vs 3.5 days; P=0.01). Transfusion rate was 18.75% (n=3) for patients with anticoagulation, 2.9% (n=1) for patients under antiplatelet therapy and 0.9% (n=1) for patients in the control group. CONCLUSION: Anticoagulation during HoLEP is a valid option but need to be proceed with carefully management. LEVEL OF PROOF: 4.

[Do initial experience with an enhanced recovery program after surgery (ERAS) improve postoperative outcomes after cystectomy?] / L'application d'un programme de réhabilitation précoce (ERAS) améliore-t-elle les résultats périopératoires après cystectomie ?

OBJECTIVE: To estimate the feasibility and the impact of an ERAS program after radical cystectomy for bladder cancer. MATERIALS AND METHODS: This was a retrospective study comparing a historical pre ERAS group, including all the patients undergoing cystectomy for bladder cancer from January 2013 to December 2015 with a classic procedure, and an interventional ERAS group after introducing an enhanced recovery protocol before, during and after surgery, from February 2016. The principal outcome was the postoperative length of stay. Secondary outcomes mesures were impact on perioperative complication rate (Clavien classification≥3B), readmission rate, reanimation length of stay, ileus rate and adherence to the ERAS protocol. RESULTS: There were no differences between the 2 groups as far as demographics characteristics are concerned. In total, 97 patients were included, 56 in the control group, and 41 in the ERAS group. The adherence to the protocol was about 65.8%. The ERAS group had statistically significantly shorter median length of stay (D19 versus D14; P: 0.021). The major complications rate (Clavien≥3B) were about 23.2% for the control group and 12.1% for the ERAS group (P: NS). The reinsertion of nasogastric tube were higher in the control group (39.3% vs 21.9%; P: NS) and the readmission rate was about 7.1% in the control group versus 14.6% in the ERAS group (P: NS). CONCLUSION: In conclusion, introduction and application of an enhanced recovery protocol (ERAS) after cystectomy for bladder cancer allowed for better management of postoperative outcomes. It is clearly feasible in cystectomy, and improve significantly the median postoperative length of stay. Moreover, it may be effective in terms of faster return of bowel function and reduction of majors complications. LEVEL OF EVIDENCE: 4.

[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.

Face Transplantation: Partial Graft Loss of the First Case 10 Years Later.

Ten years after the first face transplantation, we report the partial loss of this graft. After two episodes of acute rejection (AR) occurred and completely reversed in the first posttransplantation year, at 90 months posttransplantation the patient developed de novo class II donor-specific antibodies, without clinical signs of AR. Some months later, she developed several skin rejection episodes treated with steroid pulses. Despite rapid clinical improvement, some months later the sentinel skin graft underwent necrosis. Microscopic examination showed intimal thickening, thrombosis of the pedicle vessel, and C4d deposits on the endothelium of some dermal vessels of the facial graft. Flow magnetic resonance imaging of the facial graft showed a decrease of the distal right facial artery flow. Three steroid pulses of 500 mg each, followed by intravenous immunoglobulins (2 g/kg), five sessions of plasmapheresis, and three cycles of bortezomib 1.3 mg/m2 , were administered. Despite rescue therapy with eculizumab, necrosis of the lips and the perioral area occurred, which led to surgical removal of the lower lip, labial commissures, and part of the right cheek in May 2015. In January 2016, the patient underwent conventional facial reconstruction because during the retransplantation evaluation a small-cell lung carcinoma was discovered, causing the patient's death in April 2016.

Anti-Donor HLA Antibody Response After Pancreatic Islet Grafting: Characteristics, Risk Factors, and Impact on Graft Function.

Pancreatic islet grafting restores endogenous insulin production in type 1 diabetic patients, but long-term outcomes remain disappointing as a result of immunological destruction of allogeneic islets. In solid organ transplantation, donor-specific anti-HLA antibodies (DSA) are the first cause of organ failure. This retrospective multicentric study aimed at providing in-depth characterization of DSA response after pancreatic islet grafting, identifying the risk factor for DSA generation and determining the impact of DSA on graft function. Forty-two pancreatic islet graft recipients from the Groupe Rhin-Rhône-Alpes-Genève pour la Greffe d'Ilots de Langerhans consortium were enrolled. Pre- and postgrafting sera were screened for the presence of DSA and their ability to activate complement. Prevalence of DSA was 25% at 3 years postgrafting. The risk of sensitization increased steeply after immunosuppressive drug withdrawal. DSA repertoire diversity correlated with the number of HLA and eplet mismatches. DSA titer was significantly lower from that observed in solid organ transplantation. No detected DSA bound the complement fraction C3d. Finally, in contrast with solid organ transplantation, DSA did not seem to negatively affect pancreatic islet graft survival. This might be due to the low DSA titers, specific features of IgG limiting their ability to activate the complement and/or the lack of allogenic endothelial targets in pancreatic islet grafts.

[Notice of expert for modality and prescriptions limits of local estrogenotherapy for urinairy inconfinence in women]. / Avis d'experts sur les modalités et limites de prescription des estrogènes locaux dans l'incontinence urinaire chez la femme.

OBJECTIVE: To develop a consensus of experts on the use of local estrogens in female urinary incontinence. MATERIAL AND METHOD: Following a formalized consensus method (DELPHI), a questionnaire was produced and sent to a first round and then to a second round of experts. The questionnaire consisted of proposals for recommendations for the use of local estrogens in the context of female urinary incontinence. The Survey Monkey® survey software allowed the questionnaire to be distributed and the answers obtained to be analyzed. RESULTS: Eight experts responded to the first round questionnaire. Seven formulations were deleted, 3 amended and 4 added to the first round questionnaire following expert advice. Twenty-six experts replied to the second round questionnaire, 24 of which were complete. Ten of the 21 proposals were approved at more than 80%, including five with strong agreement regarding the recognized benefit of local estrogens in urinary incontinence due to overactive bladder, the absence of data from the literature to demonstrate over-risk of hormone-dependent cancer under local estrogens and the need for follow-up of patients under this treatment. Six proposals were not the subject of a consensus and concerned the prescription modalities (maximum duration, effective minimum dose, prescription before surgery for incontinence). CONCLUSION: Although local estrogens did not have regulatory approval in urinary incontinence, more than 80% of these experts recognized their benefit in the management of urinary incontinence in women with vulvo-vaginal atrophy, particularly in the case of urinary urge incontinence.

[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.

[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.

[Urological complications after kidney transplantation from extended criteria donors: Ureteroneocystostomy versus pyelo-ureterostomy]. / Complications urologiques après transplantation de reins issus de donneurs à critères étendus : anastomoses urétéro-vésicales versus anastomoses pyélo-urétérales.

INTRODUCTION: The use of transplants from extended criteria donors increases the number of urological complications after renal transplantation. Two different anastomosis techniques used to restore urinary continuity are compared in this study. PATIENTS AND METHODS: Retrospective study, bi-center over a period of 5 years. One hundred and seventy six patients operated at Hospices Civils de Lyon benefited from ureteroneocystostomy according to De Campos-Freire (group 1) and 167 patients operated at the Necker Hospital in Paris had a pyelo-ureterostomy (group 2). The various urological complications (fistulas, strictures, seromas, haematomas and vesico-ureteric reflux) and their care were compared. Risk factors were sought. RESULTS: The waiting time before transplantation was longer in group 2 than in group 1 (51 and 33.84 months) as the percentage of anuric patients (52.9 % against 32.9 %) (P<0.001). The cold ischemic time was shorter in group 1 (939.3minutes on average against 1325.3minutes for group 2) (P<0.001). A double J stent was put in place in 97.6 % of cases in group 2 against 84.2 % for group 1 (P<0.001). We did not find any significant difference in the occurrence of stenosis and fistulas (major complications) between the 2 groups. There were more minor complications (hematoma, seroma and vesico-ureteric reflux) in group 1 (P=0.033). There was a difference in the treatment of these complications, especially stenosis (P=0.024) with a significantly more conservative approach in group 2. Multivariate analysis found anuria, sex of recipients and donor age as independent risk factors in the onset of complications and the double J stent as a protective factor. CONCLUSION: This study does not demonstrate the superiority of a urinary anastomosis technique. The establishment of a double J stent reduces the risk of complications. Analysis of risk factors allows to propose a decision tree to guide the surgical strategy, particularly in the population of anuric recipients. LEVEL OF EVIDENCE: 5.

[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.
