Odontogenic myxoma of the mandible: a case report.

The odontogenic myxoma is a tumor of the jaws which arises from the mesenchymal portion of the tooth germ, either the dental papilla, the follicle, or the periodontal ligament. It is a slow-growing, painless, nonmetastasizing, central tumor of the jaws, chiefly the mandible. Radiographically, the classic presentation may vary from a unilocular radiolucency to a multilocular lesion with well-defined or diffuse margins. On histological study, it is composed of triangular or stellate connective cells, anastomosed by fine extensions, and embedded in abundant mucoid material. Case presentation: We present the unusual case of an odontogenic myxoma involving a 37-year-old female patient, which had acquired large dimensions and involved the right half of the mandible, including the ramus; the patient was treated with large resection surgery, with satisfying medium-term results. Clinical discussion: Early diagnosis of such lesions is very important, as the patient avoids extensive surgical procedures that involve losing a large part of the jawbones and their subsequent impact on the patient's quality of life. Conclusion: Although there is no fixed treatment plan for the management of odontogenic myxoma, treatment includes surgical management that may range from simple enucleation and curettage to surgical excision; wide surgical resection is appropriate for cases of large size to avoid recurrence.

Robot-assisted radical nephroureterectomy for upper tract urothelial carcinoma: Peri and postoperative outcomes.

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.

[Prostatic hyperplasia: Evaluation of practices in general practice, dissemination, and impact of recommendations]. / L'hypertrophie bénigne de prostate : évaluation des pratiques en médecine générale, diffusion et impact des recommandations.

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.

New technique of robot-assisted laparoscopic artificial urinary sphincter implantation in female by a posterior approach with intraoperative cystoscopic monitoring.

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.

[Acute renal failure of the donor in encephalic death: A real contraindication to kidney transplantation?] / L'insuffisance rénale aiguë du donneur en mort encéphalique : une réelle contre-indication à la transplantation rénale ?

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.

[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.

Low prevalence of Cutibacterium acnes in prostatic tissue biopsies in a French hospital.

We evaluated the Cutibacterium acnes prevalence in prostatic biopsies and characterized the strains at a molecular level. 18 out of 36 biopsies (50%) were sterile after seven days in culture. C. acnes was observed in only two biopsies. Its prevalence was low (5.6%). Finally, the molecular characterization revealed diverse clusters including phylotypes IA1, IB and II.

Feasibility and safety of laparoscopic living donor nephrectomy in case of right kidney and multiple-renal artery kidney: a systematic review of the literature.

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.

[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. LEVEL OF EVIDENCE: 3.

Transplant nephrectomy after graft failure: is it so risky? Impact on morbidity, mortality and alloimmunization.

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.

[Challenges in renal transplantation]. / La transplantation rénale et ses défis.

OBJECTIVES: To describe kidney transplantation surgical techniques and to propose strategies in high-risk recipients. MATERIAL AND METHODS: Relevant publications were identified through Medline (http://www.ncbi.nlm.nih.gov/) and Embase (http://www.embase.com/) database using the following keywords, alone or in association, "renal transplantation; peripheral arterial disease; obesity; third and fourth transplantation; robotic-assisted kidney transplant; anticoagulant therapy; dual kidney transplant". Articles were selected according to methods, language of publication and relevance. The reference lists were used to identify additional historical studies of interest. Both prospective and retrospective series, in French and English, as well as review articles and case-reports were selected. A total of 1949 articles were analyzed for arterial disease and anticoagulant therapy, 1083 for obesity, 663 for dual kidney transplants, 458 for third and subsequent procedures and 84 for robotic-assisted kidney transplantation. After careful selection, 304 publications were eligible for our review. RESULTS: Surgical assessment of future recipients is a pivotal step to anticipate technical difficulties, to interrupt clopidogrel or direct oral anticoagulants and to propose a revascularization procedure when necessary. Lack of data regarding obese recipients does not allow us to conclude about best surgical care or optimal timing but suggest that an early global management of obesity in chronic kidney disease patients is mandatory to improve access to a successful transplantation. In neurologic bladder and congenital anomalies, urodynamics and bladder function must be assessed prior to the onset of oliguria to intend an early treatment. Urinary diversion may be performed prior to or after transplantation with similar survival outcome and comparable rates of infections. Because of a rigorous selection of donors, the French dual kidney transplant program provides satisfactory outcomes, but fails in convincing surgical teams nationwide. Third and subsequent transplant procedures remain a surgical and immunological challenge, with an increased morbidity and a moderate decline in transplant survival only when donors are extended criteria' with extensive duration of waiting time between procedures. Robotic-assisted kidney transplantation is a recent technique requiring methodical evaluation. CONCLUSION: Kidney transplantation in challenging recipients implies a global understanding of patients' prognosis and benefits versus dialysis, in the context of the attribution of a valuable resource awaited by other patients on waiting list.

Nephron sparing surgery for De Novo kidney graft tumor: results from a multicenter national study.

Nephron sparing surgery (NSS) results in the transplanted population remain unknown because they are only presented in small series or case reports. Our objective was to study renal sparing surgery for kidney graft renal cell carcinomas (RCC) in a multicenter cohort. Data were collected from 32 French transplantation centers. Cases of renal graft de novo tumors treated as RCC since the beginning of their transplantation activity were included. Seventy-nine allograft kidney de novo tumors were diagnosed. Forty-three patients (54.4%) underwent renal sparing surgery. Mean age of grafted kidneys at the time of diagnosis was 47.5 years old (26.1-72.6). The mean time between transplantation and tumor diagnosis was 142.6 months (12.2-300). Fifteen tumors were clear cell carcinomas (34.9%), and 25 (58.1%) were papillary carcinomas. Respectively, 10 (24.4%), 24 (58.3%) and 8 (19.5%) tumors were Fuhrman grade 1, 2 and 3. Nine patients had postoperative complications (20.9%) including four requiring surgery (Clavien IIIb). At the last follow-up, 41 patients had a functional kidney graft, without dialysis and no long-term complications. NSS is safe and appropriate for all small tumors of transplanted kidneys with good long-term functional and oncological outcomes, which prevent patients from returning to dialysis.

De novo kidney graft tumors: results from a multicentric retrospective national study.

De novo tumors in renal allografts are rare and their prevalence is underestimated. We therefore analyzed renal cell carcinomas arising in renal allografts through a retrospective French renal transplant cohort. We performed a retrospective, multicentric survey by sending questionnaires to all French kidney transplantation centers. All graft tumors diagnosed after transplantation were considered as de novo tumors. Thirty-two centers participated in this study. Seventy-nine tumors were identified among 41 806 recipients (Incidence 0.19%). Patients were 54 men and 25 women with a mean age of 47 years old at the time of diagnosis. Mean tumor size was 27.8 mm. Seventy-four (93.6%), 53 (67%) and 44 tumors (55.6%) were organ confined (T1-2), low grade (G1-2) and papillary carcinomas, respectively. Four patients died of renal cell carcinomas (5%). The mean time lapse between transplantation and RCC diagnosis was 131.7 months. Thirty-five patients underwent conservative surgery by partial nephrectomy (n = 35, 44.3%) or radiofrequency (n = 5; 6.3%). The estimated 5 years cancer specific survival rate was 94%. Most of these tumors were small and incidental. Most tumors were papillary carcinoma, low stage and low grade carcinomas. Conservative treatment has been preferred each time it was feasible in order to avoid a return to dialysis.

[Pelvic radiotherapy and artificial urinary sphincter in women]. / Radiothérapie pelvienne et sphincter artificiel urinaire chez la femme.

OBJECTIVES: A retrospective evaluation of artificial urinary sphincter (AUS) implantation in women with previous pelvic radiotherapy (PR). POPULATION AND METHODS: From May 1987 to December 2009, on the 215 women implanted with AUS, nine (4.2%) had previous PR. We compared two groups of women, the first one without PR (group 1; n=206) and the other group with PR (group 2; n=9). Previous preop. urodynamics were realized. Patients using more than one pad per day at the end of follow-up were considered in failure. RESULTS: Mean follow-up for these two groups was 6 years (SD: 5.6 years), with a mean age of 62.8 years. Mean delay between PR and surgery was 14 years. PR was indicated for cervix cancer in 78% (7/9), endometrial cancer and ovarian cancer in 9% (1/9) each. PR was responsible of an increased rate of AUS erosion and explantation (P<0.001). In group 2, more than half of women had AUS failure and 60% for AUS erosion, versus 22% and 26% respectively in group 1. In group 2, all the AUS eroded were explanted, one third of women, with a mean delay of 59.8 months (4-140) with AUS implantation. CONCLUSION: AUS implantation in a female population with previous PR is not necessary inconsistent, but the failure rate is high. This difficult surgery should be reserved for specialized centres.

[Imperative partial nephrectomy for renal cell carcinoma: oncological and functional results]. / Néphrectomie partielle de nécessité pour carcinome à cellules rénales : résultats oncologiques et fonctionnels.

OBJECTIVES: To study oncological results and functional results after partial nephrectomy in imperative indication for the treatment of renal cell carcinoma. PATIENTS AND METHODS: From January 1990 to December 2009, 65 partial nephrectomies in 61 patients were performed in imperative indication for renal cell carcinoma. RESULTS: The mean age of patients was 59.3 years. The mean follow-up was 47.4 months. The tumours were asymptomatic in 87.5%. The average tumour diameter was 4.3 cm. Twenty-nine percent of patients relapsed after a mean time of 27.4 months. The morbidity was 38.5%. Preoperative and endpoint serum creatinine and renal clearance were respectively 119 µmol/L and 63.1 mL/min versus 137 µmol/L and 50.9 mL/min (P=0.0003; 0.0002). Overall survival at one, three, five and ten years was 98.4%, 91.2%, 91.2% and 51.9%. CONCLUSION: Partial nephrectomy in imperative indication for renal cell carcinoma has helped preserve renal function but has a significant morbidity and recurrence rate.

[Bladder necrosis after an immediate post-operative mitomycin C instillation]. / Nécrose vésicale dans les suites d'une instillation postopératoire précoce (Ipop) de mitomycine C.

Administration of intravesical chemotherapy by mitomycin C decreases the risk of recurrence in non-muscle-invasive bladder tumours. We report the case of a man, who presented a full bladder necrosis after an immediate adjuvant mitomycin C instillation. The failure of resection of the necrotic area led us to perform a total cystectomy with an intestinal reconstruction. A review of the literature showed four other cases of necrosis of the bladder or of lower urinary tract. In all cases the rules of early instillation were observed.

[Goldman Antopol syndrome associated with bilateral congenital severe factor V deficiency]. / Syndrome d'Antopol Goldman bilatéral associé à un déficit congénital sévère en facteur V.

Antopol-Goldman lesions are extremely rare. This kind of lesion is a subepithelial pelvic hematoma. This syndrome is certainly of rare occurrence and that is why a differential diagnosis of urothelial cancer in young patients who had problems with clotting must be raised. We reported a case of a 43-year-old haemophiliac with a severe congenital factor V deficit and presenting a bilateral and asynchronous Antopol Goldman syndrome. The diagnosis has been based on CT scans. The subepithelial aetiology bleeding has been shown on selective renal arteriography that allowed to cover a micro-aneurysm through the setting up of a vascular stent and a selective embolization.

[Adjustable Continence Therapy in women, middle term follow-up and a new technique for balloon positioning]. / Les ballonnets périurétraux ACT chez la femme : suivi à moyen terme et aide au positionnement.

OBJECTIVES: Evaluation of the results of Adjustable Continence Therapy (ACT) in women by a retrospective one-center study and exposure of a technique: bladder neck retrovision. PATIENTS AND METHODS: Between January 2001 and February 2009, 67 women had ACT implantation by the same surgeon for the indication of urinary incontinence by intrinsic sphincter deficiency, with mean age of 70.2 years. Mean follow-up was 24.8 months (1 to 89 months). Evaluation of functional results was realized with the research of urinary leakage when coughing or during abdominal thrust in the clinical exam, with the Urinary Symptom Profile (USP) questionnaire (since 2007), and with an analogical global satisfaction evaluation. RESULTS: More than 90% of women (n=67) have been improved at least at one medical consultation, and 60% (40/67) at last follow-up with a satisfaction index superior to 80% in 25 patients. Urinary leakage when coughing or doing abdominal thrust disappeared in 58% (36/62). An improvement of USP score was observed in 76% (19/25). Postoperative complications occurred in 37.3% (25 patients) with a mean period of 10.8 months after surgery. CONCLUSION: The ACT, indicated in stress urinary incontinence, is attractive because of the benefit-risk ratio. It could represent an alternative treatment when the artificial urinary sphincter is not technically possible, not accepted or when a reversibility is required. The bladder neck retrovision would improve the ACT surgery by precision and safety.
