RESUMEN
INTRODUCTION: Patients with neurologic bladder are at an increased risk for urolithiasis, and currently, data on mini-percutaneous nephrolithotomy in this population are limited. Our objective was to compare mini (15F)-percutaneous nephrolithotomy, standard (24F)-PCNL and flexible ureteroscopy in terms of efficacy and safety in treatment of kidney stones in patients with neurogenic lower urinary tract dysfunction (NLUTD). METHODS: We conducted a retrospective monocentric study in our neuro-urological referral centre. All consecutive patients with NLUTD and a cumulative size of renal calculi greater than 15mm or 10mm in the lower calyx, who had extraction surgery between 2005 and 2020, were included. The primary endpoint was the one-session stone-free rate (SFR) at 3 months on a CT scan. The secondary endpoints were complication (Clavien-Dindo grading system), operative time, blood loss and length of hospital stay. RESULTS: We performed 76 standard PCNL (sPCNL), 46 flexible ureteroscopy lithotripsy (fURL) and 25 miniaturized PCNL (mPCNL). The one-session SFR was 37.5% for the mPCNL group, 38.2% for the sPCNL group and 37% for the fURL group with no significant difference between the three procedures (P=0.99). Early complications, blood loss and transfusion rates were lower in the mPCNL group than in the sPCNL group (P=0.047) and comparable to fURL group. The final SFRs after a second intervention for mPCNL, sPCNL and fURL were 48%, 61.8% and 63%, respectively (P=0.67). CONCLUSION: The efficacy of mPCNL in patients with NLUTD was not different from other techniques, but a significantly lower rate of complications than sPCNL was observed. LEVEL OF PROOF: 3.

AIM: To assess the efficacy of switching to Abobotulinumtoxin A (ATA) intradetrusor injections (IDI) after failure of Onabotulinumtoxin A (OTA) IDI for the treatment of neurogenic detrusor overactivity in patients with spinal cord injury (SCI). MATERIALS AND METHODS: A single-centre retrospective chart review study. All SCI patients who started OTA IDI after 2011 and had an ATA IDI switch were included. The primary outcome was the clinical and urodynamic efficacy of the switch to ATA IIDs at the last follow-up. Secondary outcomes were initial efficacy, duration of ATA treatment, and patient outcome including the occurrence of augmentation enterocystoplasty at last follow-up. RESULTS: Sixty-two patients were included. Eighteen patients (28.9%) were initially responders to ATA IDI. Nine patients (14.5%) remained responders at last follow-up after a median of 17 months (AE 8.8-29). Thirty-two patients (51.6%) had had or were awaiting augmentation enterocystoplasty with a follow-up time of 18.5 months (IQR 8-27). Eleven patients (17.7%) were on ATA IDI with low efficacy. Seven patients (11.3%) were switched back to OTA and 3 patients (4.8%) changed their voiding pattern. CONCLUSION: Switching from OTA to ATA toxin for IDI in the treatment of detrusor overactivity after spinal cord injury have long-term efficacy for a limited number of patients but may delay the need for surgery.

INTRODUCTION: The treatment of urothelial tumours of the upper urinary tract at high risk of specific mortality is based on radical nephroureterectomy (RNU). Robotic-assisted laparoscopic radical nephroureterectomy (RARNU) is still under investigation to definitively establish the safety of this procedure in the management of urothelial tumours of the upper urinary tract. The primary objective is to evaluate the intra- and postoperative safety of RARNU and, subsequently, to evaluate the medium-term oncological results. METHODS: Our study is a retrospective, mono-centric study with a collection of RARNUs conducted between 1st January 2015 and 1st October 2021. The RARNUs were performed with the assistance of the Da Vinci Si® robot, then from 2017 the Da Vinci Xi® robot. Whenever possible, the entire procedure was carried out without re-docking. RESULTS: Between 1st January 2015 and 1st October 2021, 29 RARNUs were carried out at our centre. Complete surgery without re-docking was possible in 80% of cases with the Da Vinci Xi® robot. One patient required conversion to open surgery due to difficult dissection. 50% of tumours were classified as T3 or T4. The 30-day complication rate was 31%. The median length of hospitalisation was 5 days. The disease-free survival at the mean survival time (27.5 months) was of 75.2%. One patient had a recurrence in the nephrectomy compartment and no patient had a peritoneal or trocar orifice recurrence. CONCLUSION: Performing RARNU for the management of tumours of the upper urinary tract appears to meet the criteria of surgical safety and those of oncological safety.

INTRODUCTION: In 2015, the French Association of Urology, by the male lower urinary tract symptoms Committee, published a practices guideline for the management of prostatic hyperplasia in general practice. Five years after the publication of these recommendation, our objective is to assess their dissemination and their impact in general practice. MATERIAL: A specially designed questionnaire was distributed online via the departmental councils of the order and to all regional unions of liberal doctors. The distribution to general practitioners was at the discretion of each organisation depending on local policies. RESULTS: Two hundred and eighty responses were collected. Fifty-five percent of the population was female. 83 % of the general practitioners did not report having knowledge of the practice guideline. 77 % of doctors stated that they had not received training or information on prostatic hyperplasia in the past 5 years. Among the notable results, 51 % of general practitioners declared performing a digital rectal examination. 44 % prescribed an endorectal ultrasound. Only 7 % of doctors were aware of the existence of minimally invasive surgical techniques. CONCLUSION: The practices guideline for the management of prostatic hyperplasia in general practice proposed in 2015 by the male lower urinary tract symptoms Committee seems to be little known by general practitioners. Dissemination of these recommendations solely through publication in Progrès en Urologie seems ill-suited to consideration by general practitioners, and it seems necessary to consider other modes of dissemination. LEVEL OF EVIDENCE: 4, grade C.

INTRODUCTION: To assess the efficacy and morbidity of percutaneous nephrolithotomy (PNLT) in the treatment of renal stones in patients with neurogenic lower urinary tract dysfunction (NLUTD). METHODS: Retrospective, monocentric study including all patients with NLUTD who had undergone PNLT between 2005 and 2017. Pre-operative clinical data (neurological condition, voiding mode, preoperative urine culture ), peri-operative and post-operative data (success and morbidity) were collected from the patients' charts. Success was defined by the absence of residual fragment (RF), on imaging or intraoperative endoscopy. Partial efficacy was defined by the presence of RF lower than 4mm. Early complications were reported according to the Clavien-Dindo classification. RESULTS: In all, 53 PNLTs were performed, in 35 patients, mostly with spinal cord injury. The success and partial efficacy rates were 66.0% and 71.7% respectively. The failure rate was correlated with increased stone burden (P=0.03), increased size of the largest stone (P=0.02), and the presence of complex stones (P<0.02). The rate of early complications was 41.5%, with 27.3% major, mostly septic, and bleeding. The retreatment rate within 3 years was 41.5%. CONCLUSION: In patients with NLUTD, PNLT allows a high success rate, but with a significant rate of retreatment and infectious complications. However, NLPC remains the gold standard in this population, especially for renal stones larger 20mm, allowing a higher success rate than ureteroscopy and a lower retreatment rate.

BACKGROUND: Kidney and pancreatic transplants from controlled donation after circulatory death donors are vulnerable to ischemia-reperfusion injuries. In this context of transplant shortage, there is a need to optimize the function of these transplants and to develop novel perfusion and preservation strategies in controlled donation after circulatory death in kidney and pancreatic transplants. IN SITU PERFUSION AND PRESERVATION STRATEGIES: In situ regional normothermic perfusion improves the outcome of kidney transplants from controlled donation after circulatory death and provides equivalent results for the kidney from brain-dead donors. In situ regional normothermic perfusion is under investigation for pancreatic transplants. EX SITU PERFUSION AND PRESERVATION STRATEGIES: Perfusion on hypothermic machine perfusion is highly recommended for the kidney from controlled donation after cardiac death. Hypothermic oxygenated perfusion machine decreases the rate of graft rejection and graft failure in kidney transplantation. Ex situ normothermic perfusion is an easy way to assess renal function. In the future, kidney transplants could benefit from drug therapy during ex situ normothermic perfusion. In pancreas transplantation, hypothermic machine perfusion and ex situ normothermic perfusion present encouraging results in preclinical studies.

BACKGROUND: To evaluate in the short and mid-term the success of external sphincterotomy (ES) in neurological patients with detrusor sphincter dyssynergia (DSD). METHODS: Retrospective, monocentric study, conducted in 51 patients who had a first ES between January 2003 and June 2018, with at least two years of follow-up. The success of ES was defined by maintenance of reflex voiding mode at the end of follow-up. Secondary outcomes were early postoperative complications, rate of revision, functional impact, urodynamic follow-up and upper urinary tract impact. RESULTS: The median age was 50.6 years and the median follow-up was 4.6 years. The success rate was 80% (n=41). Ten patients had to change their voiding mode. For 5 patients, it was related to secondary detrusor low contractility. A second ES was required for 39% of patients. At the end of follow-up, there was a significant improvement in Autonomic Dysreflexia (AD) (26 vs 7 patients, P<0.001), urinary tract infections (UTI) (31 vs 15 patients, P<0.001) and a significant decrease in post-voiding residuals (200 vs 50mL, P<0.001). CONCLUSION: ES allowed to maintain reflex voiding in 80% of our patients. It significantly improves AD and UTI despite a high rate of re-operation (39%). A long-term follow-up is mandatory in order not to ignore a recurrence of bladder outlet obstruction and/or decrease in detrusor contractility, which may justify a re-operation or an alternative bladder management.

PURPOSE: The main objective of static cold storage is to reduce cellular metabolic demands to extend the period of ischaemia prior to transplantation. Hypothermia does not halt metabolism and the absence of oxygen causes a cellular shift toward anaerobic respiratory pathways. There is emerging evidence that the introduction of oxygenation during organ preservation may help ameliorate the degree of ischaemia reperfusion injury and improve post-transplantation outcomes. This review aims to appraise and summarise all published literature that utilises oxygenation to improve kidney preservation for purposes of transplantation. METHODS: We performed a scoping review of the literature using the bibliographic databases Embase and MEDLINE. The final date for searches was 20 March 2021. All research studies included were those that reported oxygen delivery during kidney preservation as well as providing a description of the oxygenation technique. RESULTS: 17 human and 48 animal studies met the inclusion criteria. The oxygen delivery methods investigated included hypothermic oxygenated machine perfusion (HOPE), oxygen carriers, two-layer method, venous systemic persufflation, hyperbaric oxygenation, normothermic machine perfusion and sub-normothermic machine perfusion. The COMPARE trial was the only study carried out with the most methodological robustness being a randomised, double blind, controlled, phase III trial that investigated the efficacy of HOPE versus HMP. CONCLUSION: A variety of studies reflect the evolution of oxygenation with useful lessons and encouraging outcomes. The first in human studies investigating HOPE and oxygen carriers are most robustly investigated strategies for oxygenation during kidney preservation and are, therefore, the best clinical references.

CONTEXT: The PP Convergences criteria group together 10 of the most significant clinical criteria for sensitization in the context of chronic pelvic pain. They are the result of a consensus of experts and represent to date the only clinical evaluation guide to identify patients with pelvic perineal pain in whom a pelvic sensitization component can be evoked. OBJECTIVE: This work concerns the psychometric validation of these criteria. The aim is to answer 3 questions: 1) is the instrument reliable (i.e., sensitive, specific and accurate)?; 2) can we define a screening score for pelvic-perineal pain by sensitization from the CPP criteria?; 3) can combinations of criteria be defined to predict pelvic-perineal sensitization from the CPP criteria? METHODOLOGY AND SUBJECTS: In total, 308 patients with pelviperineal pain were recruited during their medical consultation. PROCEDURE: Fifteen expert physicians were asked to judge the presence or absence of the 10 CPP criteria and to make a diagnosis of the presence or absence of pelviperineal sensitization in their patient. RESULTS: ROC curve analysis indicated that a score of 5 was the closest to a perfect score with a sensitivity of 95% and a specificity of 87%. They also indicate that the CPP criteria have a very good sensitivity (97%) and specificity (91%) and present globally a good reproducibility on all the criteria (Kappa>0.6). Finally, the statistical analyses reveal that the most discriminating criterion for predicting sensitization is Q8 (pain persisting after sexual activity). CONCLUSION: The CPP criteria represent a very good screening tool for pelvic sensitization. The score of 5 corresponds to the score at which the patient has sufficient clinical criteria to be classified as sensitized. LEVEL OF EVIDENCE: 4.

PURPOSE: To report the early experience of a modified technique of robot-assisted artificial urinary sphincter (AUS) implantation in female, with a posterior approach to the bladder neck and intraoperative real-time cystoscopic monitoring. METHODS: Retrospective monocentric study included all consecutive female who underwent a primary robot-assisted AUS implantation between 2017 and 2019. Real-time intraoperative cystoscopic monitoring was carried out to check the correct level of the dissection and to avoid any injury during bladder neck dissection. Perioperative and intraoperative data, functional outcomes and complications were assessed. Continence was defined as 0 to 1 pad per day. RESULTS: Twenty-four patients were included, the median age was 66 years, 23/24 (96%) had previous SUI or prolapse surgery. Two conversions to open surgery and 2 modifications of the surgical technique with anterior dissection of the bladder neck were required due to major vesicovaginal adhesions. Overall, 20 patients underwent the robotic posterior approach. Eleven intraoperative complications in 10 patients (50%) occurred, including 7 bladder injuries 4 vaginal injuries, without the need to stop the procedure. The median hospital stay was 3 days (2-7). One AUS was removed at 1 year due to vaginal erosion. At last follow-up (median 26 months (22-36)), 95% of the devices were in place and activated and the continence rate was 84%. CONCLUSIONS: Early functional results of robot-assisted AUS implantation with a posterior approach to the bladder neck and intraoperative cystoscopic monitoring are promising despite the high rate of intraoperative complications due to previous surgeries. Further evaluation of this technique is required.

Metastatic recurrence in an atypical site, such as the perineum, can occur after prostatectomy, cryotherapy, or brachytherapy, but is uncommon. To our knowledge, this is only the third case of perineal recurrence of prostatic cancer along a low dose rate brachytherapy needle track. A 64-year-old man was referred to an urologist with an increased PSA of 6.9ng/mL in December 2008. There were no urinary symptoms. Prostatic biopsies revealed a Gleason 6 adenocarcinoma (3+3), and he was treated with low dose rate brachytherapy in May 2009. Sixty-seven seeds of iodine 125 were loaded under ultrasound control, and the PSA subsequently fell to a nadir of 1.19ng/mL in November 2015. Eight years (May 2017) after the initial treatment, the PSA rose to 5.2ng/mL. Pelvic MRI and choline PET revealed a nodule in the region of the left internal obturator muscle. Nodule biopsies confirmed prostatic origin. This perineal recurrence is thus most likely related to seeding of tumour cells along the track of a brachytherapy needle. To our knowledge, this is only the fourth case of perineal recurrence of prostatic cancer along a low-dose rate brachytherapy needle track. Perineal recurrence of prostatic cancer along a LDR brachytherapy needle track can occur. Improved imaging techniques may help to identify this type of recurrence earlier and optimise treatment.

INTRODUCTION: The shortage of kidney transplants encourages the expansion of the limits of eligibility criteria for donation. Many donors who are brain dead display acute renal failure at the time of death; is this a real contraindication to harvesting? The aim of this study was to assess kidney graft survival from donors after brain death with confirmed acute renal failure, with or without anuria previous donation. MATERIALS AND METHODS: All of the transplants performed in two university hospitals between 2010 and 2017 were analyzed retrospectively. All patients who underwent single kidney transplant from a brain-dead donor with acute renal failure (ARF) were included in this study. ARI was defined here by a decrease over 50 % of glomerular filtration rate (GFR) to a threshold below 45mL/min/1.73 m2 at the time of kidney procurement. Kidney graft survival, incidence of delayed graft function (DGF) and the GFR at 12 months were analyzed. Analysis of kidney transplant survival based on pre-implantation biopsies was additionally done. RESULTS: One hundred and sixty four patients were transplanted with a kidney from donor with ARF during the selected period. At the admission in ICU the average GFR was 67,7±19mL/min/1,73m2. At the time of donation, the average age of donors was 56.4±17.7 years, the GFR was 33.7±8.0mL/min/1.73 m2 16 % of donors were anuric. Cold ischemia time (CIT) was 16.8±5.0hours. The average age of recipients was 55.6±14.1 years. 81 % of the cases were primary transplants. Graft function took place within 7.8±9.4 days after transplantation. There were two non-primary functions (PNF). One hundred and fifty two patients (93 %) had a functional graft at 12 months. The mean GFR at 12 months was 46.8±20.1mL/min/1.73 m2 and 122 patients (73 %) had a GFR greater than 30mL/min/1.73 m2. Seventy-one percent of preimplantation biopsies revealed acute tubular necrosis (ATU); no cortical necrosis was observed. Survival of theses grafts was 85 %, comparable to the total population of study (P=0,21) CONCLUSION: The acute renal failure of the brain-dead donor should not alone be systematically a contraindication to harvesting and kidney transplantation.

INTRODUCTION: Ileal ureter is a technique that consists of replacing the ureter by a segment of ileum to treat a long ureteric lesion or a lesion involving the lumbar ureter. The primary objective of our study was to assess the early perioperative morbidity of ileal ureter according to the Clavien-Dindo classification. The secondary objectives were to assess the morbidity and the medium- and long-term outcome of renal function. MATERIALS AND METHODS: Single-centre retrospective study, collecting data from patients operated between February 2005 and October 2019. All patients who underwent ileal ureter replacement surgery in our unit were included in this analysis. The ureteric defect was longer than five centimetres and involved the pelvic and/or iliac and/or lumbar ureter. All ileal ureter replacements were performed by open surgery using isoperistaltic ileal grafts. RESULTS: Twenty-one patients (11 women and 10 men) underwent total or subtotal, unilateral or bilateral ileal ureter replacement, corresponding to 25 kidneys. The grade III early postoperative complication rate was 9.5% (two cases) mainly consisting of bleeding. No grade IV or V complications were observed. With a mean follow-up of 85 months, long-term morbidity essentially consisted of infectious complications. No patients developed anastomotic strictures. Mean serum creatinine was 116.3µmol/L preoperatively, 105.6µmol/L one month postoperatively and 112.2µmol/L at last follow-up. Renal function was generally preserved or even improved, except for patients with preoperative renal failure. CONCLUSION: Ileal ureter replacement is a surgical alternative associated with low morbidity and satisfactory long-term functional results. LEVEL OF EVIDENCE: 3.

PURPOSE: To access the current status of the security and feasibility of right kidney (RK) and multiple-renal artery (MRA) laparoscopic living donor nephrectomy (LLDN) which are more challenging compared to left kidney (LK) and single renal artery (SRA) because of a shorter renal vein and more complex vascular anatomy. METHODS: We did a systematic review of the literature according to the PRISMA recommendations, reporting RK or MRA donor nephrectomy performed with a laparoscopic technique compared to LK or SRA kidney LLDN. The identified and analyzed primary outcomes of interest were operating time (OT), warm ischemia time (WIT), rate of conversion and transfusion, donor length of stay (LOS), delayed graft function (DGF) and rate of graft loss (GL). RESULTS: 16 comparative studies (1397 cases) of RK-LLDN and 12 comparative studies including 15 series (993 cases) of MRA-LLDN were selected. For RK-LLDN review, conversion rate was 0.8% and blood transfusion rate 0.2%, only one case of graft venous thrombosis was reported, OT was shorter in four studies and there was no any difference of DGF and GL rate compared to LK-LLDN. For MRA-LLDN review, conversion rate was 1.3% and blood transfusion rate 1.1%, OT and WIT were longer compared to SRA-LLDN, there were more ureteral complications in two studies, and no difference in terms of vascular complications and graft loss rate. CONCLUSION: RK-LLDN and MRA-LLDN would be similar to LK-LLDN and SRA-LLDN in terms of feasibility and safety for the donor as well as graft function results for RK-LLDN.

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.

INTRODUCTION: In France, the urinary catheterization especially in men, is governed by Article R. 4311-10 of Decree No. 2004-802 of 29 July 2004 of the Public Health Code. Although this gesture is framed by law, there is currently no French guidelines formalized on a single and easily accessible support for the technique and management of the urinary catheterization. The aim of this study was to provide a simple reference about technical aspects and management of urinary catheterization in men. MATERIALS AND METHODS: The European recommendations on urinary catheterization were updated and adapted with additional arguments in certain situations to cover all aspects of urinary catheterization. This work was conducted to improve the nurses knowledge about this topic. RESULTS: We give here a reproducible technique in order to limit complications related to the most frequent invasive gesture in urology. We also propose a scheme to harmonize the management of indwelling urinary catheterization. CONCLUSION: This work gives to nurses a practical document in order to standardize and to secure a gesture governed by dogmas since too long. The drafting of guidelines and the creation of educational tools for medical and para-medical personnel would probably improve practices in this topic. LEVEL OF EVIDENCE: 4.

PURPOSE: To determine the impact of transplant nephrectomy on morbidity and mortality and HLA immunization. METHODS: All patients who underwent transplant nephrectomy in our centre between 2000 and 2016 were included in this study. A total of 2822 renal transplantations and 180 transplant nephrectomies were performed during this period. RESULTS: The indications for transplant nephrectomy were graft intolerance syndrome: 47.2%, sepsis: 22.2%, vascular thrombosis: 15.5%, tumour: 8.3% and other 6.8%. Transplant nephrectomies were performed via an intracapsular approach in 61.7% of cases. The blood transfusion rate was 50%, the morbidity rate was 38% and the mortality rate was 3%. Transplant nephrectomies more than 12 months after renal transplant failure were associated with more complications (p = 0.006). Transfusions in the context of transplant nephrectomy had no significant impact on alloimmunization. CONCLUSION: The risk of bleeding, and therefore of transfusion, constitutes the major challenge of this surgery in patients eligible for retransplantation. Even if transfusions in this context of transplant nephrectomy had no significant impact on alloimmunization, this high-risk surgery, whenever possible, must be performed electively in a well-prepared patient.

OBJECTIVE: Pelvic-perineal pain often accompanied by pain of the perineum and pelvi-trochanteric muscles, we sought to observe the frequency of postural disturbances in relation to the pelvi-perineal muscles in patients who consult for pelvic perineal pain compared to a control population free of these pain. MATERIAL AND METHODS: The prospective monocentric study was conducted during consultations of pelvic perineal pain in the urology department of Nantes and was based on 5 clinical tests successively looking for the presence of thoraco-lumbar hinge syndrome, myofascial syndrome in the pelvic diaphragm, pelvic instability, pelvic-pedic quadrilateral dysfunction and paravertebral muscle hypertonia. RESULTS: A total of 51 subjects were included in the study and divided into two populations: 26 patients, 25 controls. Thoraco-lumbar hinge syndrome was found in 28 % of patients vs 4 % of controls (P=0.024); myofascial syndromes were present in 68 % of patients vs 25 % of controls (P=0.005); pelvic instability concerned 76 % of patients vs 33 % of controls (P=0.002); the dysfunctions of the pelvic-pedic quadrilateral concerned 96 % of the patients vs 58 % of the controls (P=0.001); paravertebral muscle hypertonia was found bilaterally in 32 % of patients vs 4 % of controls (P=0.077) and unilaterally in 36 % of patients vs 0 % of controls (P=0.001). CONCLUSION: Patients with chronic pelvic perineal pain had significantly more posture problems than non-pain patients. It seemed relevant to us that the postural assessment was integrated into their usual clinical examination. LEVEL OF EVIDENCE: 4.
