RESUMO
OBJECTIVE: The purpose of this first french guideline is to provide a clinical framework for the diagnosis, treatment and follow-up of anterior urethral strictures. The statements are established by the subgroup working on uro-genital reconstruction surgery (GURU) from the CAMS-AFU (Andrology and Sexual Medicine Committee from the French Association of Urology). MATERIAL AND METHODS: These guidelines are adapted from the Male Urethral Stricture : American Urological Association Guideline 2016, updated by an additional bibliography from January 2016 to December 2019. Twenty-seven main scenarios seen in clinical practice are identified: from diagnosis, to treatment and follow-up. In addition, this guidelines are powered by anatomical diagrams, treatment algorithms, summaries and follow-up tables. RESULTS: Anterior urethral strictures are a common condition (0,1 à 1,4 %) in men. The diagnosis is based on a trifecta including an examination with patient reported questionnaires, urethroscopy and retrograde urethrography with voiding cystourethrography. Short meatal stenosis can be treated by dilation or meatotomy, otherwise a urethroplasty can be performed. First line treatment of penile strictures is urethroplasty. Short bulbar strictures (<2cm) may benefit from endourethral treatment (direct visual internal urethrotomy or dilation). In case of recurrence or when the stenosis measures more than 2 cm, a urethroplasty will be proposed. Repeated endourethral treatment management are no longer recommended except in case of palliative option. Urethroplasty is usually done with oral mucosa graft as the primary option, in one or two stages approach depending on the extent of the stenosis and the quality of the tissues. Excision and primary anastomosis or non-transecting techniques are discussed for bulbar urethra strictures. Follow-up by clinical monitoring with urethroscopy, or retrograde urethrography with voiding cystourethrography, is performed at least the first year and then on demand according to symptoms. CONCLUSION: Anterior urethral strictures need an open surgical approach and should be treated by urethroplasty in most cases. This statement requires a major paradigm shift in practices. Training urologist through reconstructive surgery is the next challenge in order to meet the demand.

PURPOSE: We report the natural history and prognosis of tumors after augmentation enterocystoplasty, with a molecular analysis using an oncogene panel to search for potential targeted therapies. MATERIALS AND METHODS: This multicenter, nationwide, retrospective study included 16 patients. A panel of 21 clinically relevant oncogenes was tested on archival tumor specimens using next-generation sequencing. Survival rate was the main clinical outcome and sequences were compared to the reference genome for the genetic outcome. RESULTS: Augmentation enterocystoplasties were performed mainly for congenital neurogenic bladder and bladder exstrophy at a median patient age of 17 years (range 4 months to 45 years). Most of the malignancies were diagnosed because of clinical manifestations, with a median latency period of 20 years. Adenocarcinomas were mainly found after gastrocystoplasty, whereas urothelial cell carcinomas were typically found after colocystoplasty. Of the 16 patients 13 were diagnosed at an advanced stage of the disease (positive lymph nodes in 7, distant metastases in 6). The overall 1-year survival rate was 56%. Only 3 patients remained disease-free at a median followup of 70 months. Of the 9 tumors with analyzable DNA 4 were wild-type and 5 harbored missense mutations (KIT-p.Pro573Ser, PDGFRA-p.Glu587Lys, KRAS-p.Gly12Asp, ERBB4p.Arg484Lys, CTNNB1-p.Ser37Phe and p.Ser47Asn). CONCLUSIONS: Malignancy after augmentation enterocystoplasty is diagnosed late with frequent metastases and a very low 1-year survival rate. More than half the tested samples harbored missense mutations in oncogenes accessible to targeted therapies. An international collaboration to enlarge the genetic panel analysis of these tumors may offer new therapeutic hope to patients.

PURPOSE: Management of pregnancy and delivery in women with lower urinary tract reconstruction is challenging and the currently available literature is insufficient to guide clinical practice. We report pregnancy and delivery outcomes in this specific population. MATERIALS AND METHODS: We conducted a national multicenter retrospective study (16 centers) including 68 women with 96 deliveries between 1998 and 2019. These women had at least 1 successful pregnancy and delivery after augmentation enterocystoplasty, catheterizable channel creation and/or artificial urinary sphincter implantation. Maternal and fetal complications during pregnancy and delivery were reported, as well as postpartum functional outcomes, according to the delivery mode. The chi-square test and Student's t-test were used to compare categorical and continuous variables, respectively. RESULTS: Overall 32% of reported pregnancies were complicated by febrile urinary tract infections, 13.5% by renal colic and 14.6% required upper urinary tract diversion. In addition, 10% of patients reported transient self-catheterization difficulties and 13.5% reported de novo or increased urinary incontinence. The preterm delivery rate was 35.3%. Elective C-section was performed in 61% of pregnancies. Twenty complications occurred during delivery (20%), including 19 during elective C-section. Urinary continence at 1 year was unchanged for 93.5% of deliveries. Delivery mode (p=0.293) and multiparity (p=0.572) had no impact on urinary continence. CONCLUSIONS: In this population C-section appeared to be associated with a high risk of complications. In the absence of any obstetric or neurological contraindications, vaginal delivery should be proposed as the first line option to the majority of these women.

INTRODUCTION: This study analyzed long-term functional outcome of continent catheterizable channels with the Mitrofanoff procedure, their continence, complications and the satisfaction of the patients. MATERIAL AND METHOD: Data from patients who underwent a Mitrofanoff procedure at our institution from June 1997 to March 2015 were retrospectively collected. All patients were contacted at the end of the study, a survey was submitted to them. RESULTS: Sixty-seven patients underwent a continent cystostomy with the Mirtrofanoff procedure. Forty-five patients had the inclusion criteria: 18 years old or older, no previous urinary diversion with a minimum of 6 months of follow-up. The cohort comprised mainly neurologic bladder (84 %) with spinal cord injuries (54 %) or spina-bifida patients (15 %). Median age was 35 years old [22-49]. Median follow-up was 64months [39-90]. The surgical procedure used an appendicular channel: 30 patients (67 %) or a continent ileal plasty: 15 patients (33 %). At the end of follow-up: 88 % patients have a full cystostomy continence, 89 % full uretral continence. Twenty-nine patients had one (41 %) or more reinterventions. Reasons for the 58 reinterventions were: stomal stenosis (31 %), uretral incontinence (29 %), cystostomy incontinence (15 %), lithiasis (9 %). Those reinterventions were done with a local surgery (31 %) or an endoscopic surgery (35 %). Overall early adverse events (<30days) or delayed (>30days) adverse events were similar (P=0.93) in appendicovesicostomy group or continent ileal plasty group. Ninety-four percent patients described a satisfactory urinary comfort. The cystostomy was considered esthetic by 71 %, its realization allowed an improvement of the quality of life for 89 % of them. CONCLUSION: Continent channels in adults demonstrate favorable long-term outcomes even if reinterventions could be necessary to maintain a continent and catheterizable channel. Despite reinterventions, patients remain satisfied by the Mitrofanoff procedure which facilitate the process of clean intermittent catheterization. LEVEL OF EVIDENCE: 4.

INTRODUCTION: GreenLight photoselective vaporisation of the prostate (PVP) offers an endoscopic alternative to open prostatectomy (OP) for treatment of large adenomas. This study compares long-term functional outcome of both techniques in patients with Benign prostatic obstruction (BPO)>80g. MATERIAL AND METHOD: Data from patients who underwent surgical treatment for BPO>80g from January 2010 to February 2015 at our institution were retrospectively collected and compared according to surgical technique. Patient's demographics, surgeon's experience, operative data and long-term functional results were analyzed, using IPSS and International continence society (ICS) male questionnaire associated with Quality of life scores (IPSS-QL and ICS-QL). Predictors of long-term outcome were also assessed. RESULTS: In total, 111 consecutive patients, 57 PVP and 54 OP, were included in the study with a mean follow-up of 24 and 33 month respectively. Patient's age, Charlson score, preoperative IPSS and urinary retention rates were similar. Mean prostatic volume was superior in the OP group (142 versus 103g, P<0.001). Transfusion rate was lower after PVP (P=0.02), despite a more frequent anticoagulant use. Length of hospital stay and urinary catheterization were shorter after PVP (P<0.001), with however a higher rate of recatheterization (RR=4.74) and rehospitalization (RR=10.42). Long-term scores were better after OP for IPSS (1 versus 5, P<0.001), IPSS-QL, ICS, ICS-QL. On multivariate analysis, prostatic residual volume was the only predictor of long-term IPSS but not ICS. CONCLUSION: Long-term functional outcome are better after OP compared to PVP. However, PVP offers good results, allowing to safely operate patients taking anticoagulants, regardless of prostatic volume. Endoscopic enucleation may the compromise between both techniques. LEVEL OF EVIDENCE: 4.

INTRODUCTION: The purpose was to describe the management of intraparenchymal pseudoaneurysm (PA) after blunt renal trauma in our center, and to review the cases published in the literature, in order to propose a management algorithm. MATERIALS AND METHODS: We reviewed the files of 325 patients included in a prospective database, from July, 2004, to May, 2016. A systematic review of the published cases was done with the keywords "blunt renal trauma" and "pseudoaneurysm" in Pubmed (excluding arteriovenous fistulas, open renal traumas and extraparenchymal PA) allowing us to analyze 29 extra cases. Management of these patients in our center is decribed. RESULTS: Among 325 kidney trauma patients, 160 (49.3%) had grade IV and V renal trauma. Conservative management was done in 93.2%. We noted 8 cases of PA, with an incidence of 2.5%. Four patients required angioembolization. Four patients were treated by watchful waiting, with 2 cases of spontaneous occlusion, one case of absence of regression and embolization, and one case of occult hemorrhage. All PA with a favorable outcome were less than 1cm. The mean relative renal scintigraphic function at 6 months of the kidneys requiring embolization was 71.6%. The literature review reported 29 published cases, among whom 26 required embolization, with a success rate of 84.6%. Two cases were just watched, but one was finally embolized in the absence of regression. CONCLUSION: Pseudoneurysm formation after blunt renal trauma is a rare complication (2.5%). In case of clinical symptoms or hemodynamic instability, embolization allows a good renal preservation. Watchful waiting seems to be an option in asymptomatic cases with a PA less than 1cm. LEVEL OF EVIDENCE: 5.

In 2015, Annecy Hospital was the first French hospital to perform non-heartbeating organ donation from a Maastricht category III donor (patient awaiting cardiac arrest after withdrawal of treatment). Non-heartbeating organ donation (NHBD), performed in France since 2006, had initially excluded this category, due to ethical questions concerning end of life and treatment withdrawal, as well as technical specificities linked to this procedure. Grenoble University Hospital and Edouard-Herriot Hospital in Lyon then performed the first kidney transplants, with satisfactory outcomes in both recipients. This article presents the details and results of this new experience, challenging both on a deontological and organizational level. Functional outcomes of kidney grafts from NHBD are now well known in the literature and confirm their benefit for patients, with similar results to those from heartbeating donors (HBD). International experiences concerning specifically Maastricht category III NHBD are encouraging and promising.

OBJECTIVE: To establish 18 fluorocholine-positron emission tomography/computed tomography (F-PET/CT) performances for the detection of local recurrence in a population of patients with biochemical failure after primary curative treatment for localized prostate carcinoma. MATERIAL AND METHOD: From February 2011 to February 2014, 55 patients underwent a F-PET/CT for biochemical relapse after primary radical therapy for prostate cancer localized or locally advanced. Primary therapies for prostate cancer were 19 radical prostatectomy, 18 radiotherapy, 13 radiotherapy with hormonal treatment, 3 brachytherapy. The median age was 65 years (50-79). The initial staging was 17 T1, 23 T2 and 15 T3, 52 were N0 and N1 3. The median PSA was 12 (3-127). The Gleason score was less than 7, equal to 7 and greater than 7 at 21, 25 and 9 patients respectively. The average time to recurrence was 69.5 months (8-147) with a median PSA of 2.9 ng/mL (0.48-41). RESULTS: In 42 cases, F-PET/CT showed uptake, suggesting a recurrence, metastatic (6), nodal (26) or local isolated (10). The focal uptake in PET commissioned in 5 cases prostate biopsy, confirming the histological recurrence of prostate cancer in 4 cases. Among the 10 patients with isolated local recurrence, 8 underwent salvage radiotherapy. Of the 13 cases where the (F-PET/CT) showed no recurrence, 7 multiparametric MRI were performed. The MRI showed a local recurrence in 3 patients, the diagnoses were confirmed with prostate biopsy for two of them. CONCLUSION: In our study, for the patients with biochemical relapse of prostate adenocarcinoma localized or locally advanced, (F-PET/CT) was able to detect local recurrence isolated in nearly half the cases but did not show sufficient sensitivity to exclude recurrence local if negative. It does not replace MRI or additional prostate biopsy.

Faecal incontinence and urinary incontinence are common and often associated. Sacral neurostimulation is a validated technique for treating each of these two types of incontinence, taken separately. The purpose of this study was to review the literature on the results of this treatment for double incontinence. A literature search was conducted using MEDLINE, PubMed, EMBASE and the Cochrane Library using the keywords "faecal incontinence", "anal incontinence", "urinary incontinence", "urgency", "urinary disorder", "neurostimulation", "sacral nerve stimulation" and "electric nerve stimulation". We limited the search to English-language articles on faecal and urinary incontinence in adults published from 1995 to the present. We identified six articles, comprising 113 patients who were followed for 3-62 months. Improved faecal incontinence was observed in 44-100 % of cases, while improved urinary incontinence was observed in 20-100 % of cases. Patient satisfaction with the correction of double incontinence, both anal and urinary, was highly variable, ranging from 20 to 100 %. As anal incontinence and urinary incontinence are often associated and are sometimes responsive to sacral neuromodulation, it seems attractive to provide such treatment for double incontinence, to improve both digestive and urinary symptoms.

Reoperating an hypospadias requires a reconstructive strategy that considers the patient's disturbing symptoms, located on the urethra (stenosis, fistula, persistent hypospadias, urethral hair) as well as on cavernous bodies and penile skin. Though experience validates it, this global and gradual approach has been barely described. It takes up latest hypospadiology work through several steps: after urethroscopy, penis is freed from penile skin in order to treat first a potential residual curvature in four steps. Then, the urethral issue is fixed differently according to the state of the penile urethra. In addition, a buccal mucosal urethroplasty will be likely to be occurred, in one or two times.

INTRODUCTION: Congenital abnormalities of the penis are usually diagnosed at birth and pose aesthetic and functional problems sometimes requiring surgical management. METHODS: A literature review was conducted on Medline considering the articles listed until January 2012. RESULTS: Hypospadias is the most common malformation (1 in 250 boys. Familial forms: 7%). The causes remain hypothetical but the doubling of the incidence in 30 years could be linked to fetal exposure to endocrine disruptors "estrogen-like" used in the food industry in particular. Surgical treatment is usually intended to improve the aesthetic appearance but sometimes, in case of significant curvature or posterior meatus, necessary for normal sexual life and fertility. Other malformations (epispades, buried penis, transpositions, twists and preputial abnormalities) as well as management for functional or aesthetic consequences of these malformations in adulthood require complex surgical care in a specialized environment. CONCLUSION: The improvement of surgical techniques and pediatric anesthesia allows an early and effective specialized surgical approach of penile malformations. Management of sequelae in adulthood must be discussed and requires experience of surgical techniques on pediatric and adult penis.

OBJECTIVE: To describe the evolution of epidemiology and management of renal cell carcinoma and their impact on overall and progression-free survivals. PATIENTS AND METHODS: We reviewed the files of consecutive patients with renal cell carcinoma in our center between January 2000 and December 2011. Patients with confirmed diagnosis on histology who underwent radical nephrectomy, partial nephrectomy or thermoablation were included. Benign tumors were excluded. Epidemiologic and therapeutic data during the period of study were compared. Overall and progression-free survivals divided in three periods were compared by Kaplan-Meier curves. RESULTS: Four hundred and forty-nine patients were included with a median age of 60 years old [21; 89], and median follow-up of 39 months. Tumor histology was clear cell carcinoma in 75.9% of cases. During the period of study, patients with ASA score upper than 3 increased from 20.4% to 47.8%, tumor size decreased from 58.4mm to 49.5mm and incidental tumor discovery increased from 59.1% to 71.6%. Nephron-sparing surgery increased from 19.7% to 44%. Overall survival and progression-free survival was not different during this period (P=0.071 and P=0.582). CONCLUSION: The increase in early incidental discovery of renal cell carcinoma allowed nephron-sparing surgery in spite of patients with more comorbidities, with stable overall and progression-free survivals in our series.

OBJECTIVE: To evaluate impact of the use of haemostatic agent in partial nephrectomy on perioperative outcomes. MATERIAL AND METHODS: We reviewed the files of patients candidates for partial nephrectomy in our center between 2005 and 2010. The use of haemostatic agent and surgical procedure data were noted. Perioperative outcomes in haemostatic agent group were compared with perioperative outcomes in conventional surgical haemostasis group. RESULTS: Among the 131 patients included, haemostatic agent was used in 91 cases (69.5%). There was no statistically difference between the two groups on age, sex, BMI, ASA score, tumor size and RENAL score. The use of haemostatic agent was more frequent for patients operated with laparoscopy (10.7%, P=0.04). Concerning perioperative outcomes, there was no difference between the two groups on surgical complications, transfusions, conversion to radical nephrectomy and hospital stay. Median warm ischaemia time was comparable into the two groups. In multivariate analysis, haemorrhage, complications and transfusions were not predicted by the use of haemostatic agent. CONCLUSION: Use of haemostatic agent in partial nephrectomy had no benefice on perioperative outcomes in our series. Rapport between utility and cost for these agents must be discussed in partial nephrectomy.

BACKGROUND: computed tomography angiography (CTA) and magnetic resonance angiography (MRA) are both used in the preoperative assessment of vascular anatomy before donor nephrectomy. Our objective was to determine retrospectively and to compare the sensitivity of CTA and MRA imaging in preoperative renal vascularisation in living kidney donors. PATIENTS AND METHODS: between 1999 and 2007, 42 kidney donors were assessed in our center: 27 by MRA, 10 by CTA, and five by both techniques. Images were interpreted using multiplanar reconstructions. Results were compared retrospectively with peroperative findings; discordant cases were re-examined by an experienced radiologist. Numbers of vessels detected with imaging methods was compared with numbers actually found at the operating time. RESULTS: MRA showed 35/43 arteries (Se 81.4 %) and 33/34 veins (Se 97.1 %), and CTA showed 18/18 arteries (Se 100 %) and 15/16 veins (Se 93.8 %). The presence of multiple arteries was detected in only one third of cases (3/9) on MRI scans; this difference was statistically significant. The missed arteries were not detected on second examination of the MRI scans with the knowledge of peroperative findings. CONCLUSION: MRA is less sensitive than CTA for preoperative vascularisation imaging in living renal donors, especially in the detection of multiple renal arteries.

OBJECTIVE: To determine the efficiency and the role of ureteroscopy in the treatment of urolithiasis in children. METHODS: A multicenter retrospective study was conducted between January 2006 and March 2008 in the department of pediatric surgery and urology of Besançon, Lyon and Grenoble. The clinical data of 17 children having benefited from one or more ureteroscopy procedures for urolithiasis were analyzed. These data concerned age, sex, antecedents of metabolic diseases, existence of a malformed uropathy, how the urolithiasis was discovered, therapeutic indications, endoscopic procedures, type of endoscopic treatment for urolithiasis, results and complications. RESULTS: Twenty-six ureteroscopies were carried out for 17 children (eight girls and nine boys) aged between 9 months and 12 years (mean: 5 (1/2) years old) as a first-line treatment or after extracorporeal shock wave lithotripsy. A 6/7,5 Fr semi-rigid ureteroscope was used in all case. Only once, the operator chose a flexible ureteroscope. Lithotripsy was carried out 15 times with YAG Holmium laser, four times with Swiss Lithoclast and six times by simple extraction with a Dormia type basket .A stent probe was left in place after endoscopy for 14 children. The "stone free" rate was 88% with an average hindsight of 11 months. Two incidents without major complication were recorded: a section of the guide by the laser beam and a perforation with extravasation of the contrast agent. CONCLUSION: Ureteroscopy is the first-line treatment in isolated ureteral urolithiasis. On the other hand, LEC remains the treatment of choice for Starghon calculi, since LIC should be offered only in the event of failure of LEC.
