RESUMO
PURPOSE: We assess the efficacy, safety, and predictive factors for failure of synthetic mid-urethral slings for the treatment of urinary incontinence in a large cohort of women with neurogenic lower urinary tract dysfunction. MATERIALS AND METHODS: Women aged 18 years or older who received a synthetic mid-urethral sling for stress urinary incontinence or mixed urinary incontinence in 3 centers between 2004 and 2019 and who had a neurological disorder were included. Exclusion criteria were less than 1 year of follow-up, concomitant pelvic organ prolapse repair, previous synthetic sling implantation, and no baseline urodynamics. The primary outcome was surgical failure, defined as recurrence of stress urinary incontinence during follow-up. Kaplan-Meier analysis was used to estimate the 5-year failure rate. Adjusted Cox proportional hazard model was used to identify factors associated with surgical failure. Complications and reoperations during the follow-up have also been reported. RESULTS: A total of 115 women with a median age of 53 years were included. The median follow-up duration was 75 months. The 5-year failure rate was 48% (95 CI 46%-57%). Age above 50 years, negative tension-free vaginal tape test and transobturator route were associated with surgical failure. Thirty-six patients (31.3%) underwent at least 1 reoperation for complications or failure, and 2 required definitive intermittent catheterization. CONCLUSIONS: Synthetic mid-urethral slings may be an acceptable alternative to autologous slings or artificial urinary sphincters for the treatment of stress urinary incontinence in a selected group of patients with neurogenic lower urinary tract dysfunction.

PURPOSE: The management of major renal trauma has shifted in the last decade in favor of a nonoperative approach. Our level 1 trauma center promotes this approach with the objective of renal function preservation. However, certain situations still require surgery. In this study we analyze predictors of surgery and long-term outcomes after conservative management. MATERIALS AND METHODS: From January 2004 to March 2015 we prospectively collected data from all patients admitted to our institution for high grade blunt renal trauma (grades IV and V). Nonoperative management was considered successful when patients did not undergo surgical exploration, regardless of angioembolization or endoscopic treatment. RESULTS: Of 306 patients with renal trauma 151 presented with major injuries, including 124 grade IV and 27 grade V. Nonoperative management was successful in 110 (89%) cases of grade IV and 14 (52%) cases of grade V lesions. Deceleration mechanism (p=0.03), associated lesions (p=0.001), percentage of devitalized parenchyma (p=0.012), angioembolization (p <0.001), hemodynamic instability (p <0.001) and low hemoglobin (p=0.001) were more frequent in patients treated surgically. On multivariate analysis grade (OR 7.36, p=0.01) and hemodynamic instability (OR 4.18, p=0.04) were the only independent predictors of surgical treatment. Long-term followup of preserved kidneys revealed a remaining 40% and 0% relative renal function after grade IV and V injuries, respectively. Only devascularized parenchyma greater than 25% predicted the decline of long-term renal function. CONCLUSIONS: Nonoperative management can and should be performed safely in cases of grade IV injuries whenever possible, with valuable long-term renal function. It can also be initiated in grade V cases. However, surgeons should consider nephrectomy with the onset of any suspicious symptoms.

OBJECTIVE: AI-derived language models are booming, and their place in medicine is undefined. The aim of our study is to compare responses to andrology clinical cases, between chatbots and andrologists, to assess the reliability of these technologies. MATERIAL AND METHOD: We analyzed the responses of 32 experts, 18 residents and three chatbots (ChatGPT v3.5, v4 and Bard) to 25 andrology clinical cases. Responses were assessed on a Likert scale ranging from 0 to 2 for each question (0-false response or no response; 1-partially correct response, 2- correct response), on the basis of the latest national or, in the absence of such, international recommendations. We compared the averages obtained for all cases by the different groups. RESULTS: Experts obtained a higher mean score (m=11/12.4 σ=1.4) than ChatGPT v4 (m=10.7/12.4 σ=2.2, p=0.6475), ChatGPT v3.5 (m=9.5/12.4 σ=2.1, p=0.0062) and Bard (m=7.2/12.4 σ=3.3, p<0.0001). Residents obtained a mean score (m=9.4/12.4 σ=1.7) higher than Bard (m=7.2/12.4 σ=3.3, p=0.0053) but lower than ChatGPT v3.5 (m=9.5/12.4 σ=2.1, p=0.8393) and v4 (m=10.7/12.4 σ=2.2, p=0.0183) and experts (m=11.0/12.4 σ=1.4,p=0.0009). ChatGPT v4 performance (m=10.7 σ=2.2) was better than ChatGPT v3.5 (m=9.5, σ=2.1, p=0.0476) and Bard performance (m=7.2 σ=3.3, p<0.0001). CONCLUSION: The use of chatbots in medicine could be relevant. More studies are needed to integrate them into clinical practice.

OBJECTIVE: To predict the outcomes of a non-operative approach to managing urinary extravasation after blunt renal trauma. PATIENTS AND METHODS: A prospective observational study was conducted between January 2004 and October 2011. First-line non-operative management was proposed for 99 patients presenting with a grade IV blunt renal injury according to the revised American Association for the Surgery of Trauma (AAST) classification. Among them, 72 patients presented with a urinary extravasation. Management and outcomes were recorded and compared between patients presenting and those who did not present with urinary leakage. Relative postoperative renal function was assessed 6 months after the trauma using dimercapto-succinic acid renal scintigraphy. Predictors of the need for endoscopic or surgical management and long-term renal function were evaluated on multivariate analysis. RESULTS: Among patients with urinary leakage, endoscopic ureteric stent placement and open surgery were required in 37% and 15%, respectively. On multivariate analysis, fever of >38.5 °C and ureteric clot obstruction were independent predictors of the need for ureteric stent placement. The only predictor of open surgery was the percentage of devitalised parenchyma. Long-term renal function loss was correlated to the percentage of devitalised parenchyma and associated visceral lesions. Urinary extravasation did not predict surgical intervention or long-term renal function loss. CONCLUSIONS: Urinary extravasation after blunt renal trauma can be successfully managed conservatively and does not predict long-term decreased renal function or surgery requirement. A devascularised parenchyma volume of >25% predicts a higher rate of surgery and poorer renal function.

OBJECTIVE: To evaluate the RENAL nephrometry score (RNS) as a predictor of the perioperative outcomes of a partial nephrectomy. PATIENTS AND METHODS: A retrospective review of 177 consecutive patients who were candidates for an open partial nephrectomy (OPN, n = 159) or a laparoscopic partial nephrectomy (LPN, n = 18) from August 2008 to January 2011 was undertaken. Tumour complexity was stratified into three categories: low (4-6), moderate (7-9) and high (10-12) complexity. Complications, and surgical and renal outcomes were recorded and analysed. Predictors of conversion to radical nephrectomy (RN) and complications were assessed using univariate and multivariate logistic regression. Multiple linear regression was used to evaluate the prediction of postoperative estimated glomerular filtration rate (eGFR) and warm ischaemia time (WIT). RESULTS: The median RNS was 7 (interquartile range 6-9). Tumour complexity was assessed as low in 72 (40.6%), moderate in 87 (49.2%) and high in 18 patients (10.2%). There were no significant differences among the three groups with respect to demographic characteristics, operating time, estimated blood loss, transfusion, length of stay, complications and positive surgical margins. Conversion to RN occurred in 29 patients (16.3%). RNS was significantly associated with an increased risk of conversion to RN (odds ratio [OR] = 3.5, P = 0.01 and OR = 6.7, P = 0.005, respectively, for moderate vs low, and high vs low complexity groups). On multivariate analysis, RNS was the only independent predictor of WIT (P = 0.03) and conversion to RN (P = 0.008), but failed to predict postoperative eGFR (P = 0.84) and the occurrence of major complications (P = 0.91). CONCLUSIONS: In the present series, RNS predicted an increased risk of conversion to RN and prolonged WIT. RNS was not a predictor of complications and postoperative renal function.

INTRODUCTION: Urethral mesh perforation is a rare complication of mid-urethral sling resulting in a lack of clear management guidelines. Thus, we aimed to determine management options and their respective outcomes in terms of erosion resolution and continence. METHODS: A literature review was performed by extracting studies from the PubMed, Cochrane, and Google Scholar from January 1996 to December 1, 2022. Only French and English language studies were included. A total of 227 papers were screened and assessed for eligibility. RESULTS: Forty-eight studies were included in the final analysis, for a total of 224 patients. Treatment options consisted of conservative, endoscopic, transurethral, and transvaginal approaches. Conservative treatment was associated with a 100% risk of persistence or recurrence of urethral perforation, while the failure rates for endoscopic, transurethral, and transvaginal approaches were 33%, 7.5%, and 7%, respectively. Most patients suffered from stress urinary incontinence after reconstructive management. The most common symptoms at the time of presentation were overactive bladder and pain. The mean time between the onset of symptoms and diagnosis was 10 months. About half of the urethral mesh perforations were diagnosed within the first years after the initial sling insertion. CONCLUSIONS: Multiple management options for sling penetration of the urethra have been described in the literature. Transvaginal sling resection with consecutive tissue interposition seems to carry the lowest risk of erosion recurrence; however, all treatment options are associated with a high relapse rate for stress urinary incontinence.
RESUMO
PURPOSE: The management of high grade blunt renal injury has evolved with time to become increasingly conservative with the ultimate objective of renal preservation. We evaluated relative renal function with dimercapto-succinic acid renal scintigraphy 6 months after major renal trauma (grade IV or V). MATERIALS AND METHODS: This prospective observational study was done between January 2004 and April 2010. All patients who presented with grade IV or V renal trauma and were treated conservatively were included in analysis. Patient and trauma characteristics, and initial management were recorded. Relative renal function was evaluated by dimercapto-succinic acid renal scintigraphy 6 months after trauma. RESULTS: A total of 88 patients were included in the study. Conservative management was possible in 79 patients (90%), including 69 and 10 with grade IV and V trauma, respectively. Dimercapto-succinic acid renal scintigraphy was done at 6 months for 22 patients (28%). Mean relative renal function for grade IV and V injuries was 39% and 11%, respectively (p=0.0041). The percent of devascularized parenchyma (p=0.0033) and the vascular subtype of grade IV injuries (p=0.0194) also correlated with decreased renal function. No complication or de novo arterial hypertension was noted. CONCLUSIONS: Conservative treatment achieves the objective of renal function preservation for grade IV lesions. Grade V and specific subtypes of grade IV injury have a poor functional outcome. Further study must be performed to determine which patients will benefit from conservative treatment vs early nephrectomy to avoid a longer hospital stay and useless procedures.

BACKGROUND: Sacral nerve stimulation is a recognized treatment for fecal and urinary incontinence. Few articles have been published about patients presenting with both types of incontinence. OBJECTIVE: The aim of this study was to report the functional results in patients operated on for simultaneous fecal and urinary incontinence by the use of sacral nerve stimulation. DESIGN: This study is a retrospective analysis of prospectively collected data. SETTINGS: The investigation was conducted in the academic departments of colorectal surgery and urology. PATIENTS: Between January 2001 and March 2010, 57 consecutive patients (54 women) with a mean age of 58 years (range, 16-76) were included. INTERVENTIONS: Two-stage sacral nerve modulation (test and implant) was performed. MAIN OUTCOME MEASURES: Functional study before testing, at 6 months, and at the end of follow-up after implantation included the use of the Cleveland Clinic incontinence score, Urinary Symptoms Profile, Fecal Incontinence Quality of Life score, and the Ditrovie score. Patient satisfaction with the technique was evaluated at a median follow-up of 62.8 months. RESULTS: : Fecal incontinence improved from 14.1/20 to 7.2/20 at 6 months and 6.9/20 at the end of follow-up. Urinary incontinence, mainly urge incontinence (47% of patients), and urgency frequency (34% of patients) improved at 6 months and end of follow-up, but not retention and dysuria. Specific quality of life was improved for fecal and urinary incontinence at 6 months and end of follow-up. At the end of follow-up, 73% patients were highly satisfied with the technique, but 9% felt their condition had deteriorated. The reoperation rate was 29%, of which 12% were indicated because of a complication. LIMITATIONS: This study was limited by its retrospective nature and the multiple causes of incontinence. CONCLUSION: Fecal and urinary incontinence, studied by symptoms scores and specific quality-of-life scores, are improved in patients receiving sacral nerve stimulation for double incontinence.

AIMS: The aims of this study were to evaluate the efficacy and safety of endoscopic treatment of primary obstructive megaureter in children, and to assess its long-term outcome. METHODS: Case files of 35 children who had endoscopic treatment of symptomatic primary obstructive megaureter between 2006 and 2016 were retrospectively analyzed. All children had ureterovesical junction dilatation with one or more ureteral dilators, and insertion of a JJ stent. An analysis of the case files and a comparison between pre- and postoperative ultrasound and scintigraphy findings were performed. RESULTS: The study population consisted of 22 boys and 13 girls aged between 2 months and 16 years. The follow-up period ranged from 8 months to 10 years. Twenty-one children (60%) were under 2 years at the time of treatment. The average duration of JJ stenting was 7 weeks (3-16 weeks). Thirty-four of 35 children (97%) were considered definitively cured, that is, asymptomatic with preserved renal function. Two children required open surgery for a failed endoscopic treatment procedure. Secondary reimplantation surgery was only necessary in one case (1/35) after technically satisfactory endoscopic treatment. Twelve of 35 children had a complication, including two Clavien III complications. Comparison of pre- and postoperative ultrasonography showed a significant decrease in ureteral diameter in 31 cases. Postoperative scintigraphy showed a significant improvement in the ureteral leaking curve in 20 children. CONCLUSION: In our experience, endoscopic treatment of congenital obstructive megaureter in pediatrics seems to be safe and effective. It is proposed as a first-line treatment for children requiring an intervention, even for young children under 2 years.

BACKGROUND: To evaluate the management and long-term renal function with DMSA scintigraphy in pediatric severe traumatic kidney injury grade IV and V at the trauma center of Grenoble Teaching Hospital. METHODS: This is a single-center observational retrospective study between 2004 and 2014. All children younger than 15 years and managed at the Grenoble teaching Hospital for a severe trauma kidney injury grade IV or V were included. The trauma grade was radiologically diagnosed on arrival at hospital, using the classification of the American Association for Surgery of Trauma. The management followed the algorithm in effect in the establishment. The assessment of the renal function was performed by a DMSA scintigraphy after at least 6 months from the injury. RESULTS: Twenty-one children were managed for a severe renal trauma (16 IV and 5 V). The diagnosis was initially made by an ultrasonography (eight cases) or a computed tomography scan (13 cases). A child with a severe renal trauma IV underwent nephrectomy on day 6 of the trauma. Eleven children needed a therapeutic procedure (three embolizations, four double J stents, one arterial stent, one peritoneal lavage for a splenic hemoperitoneum, four pleural drainages). A DMSA scintigraphy was performed in 15 patients to assess the function of the injured kidney: 11 of 16 severe renal trauma IV with an average of 39.4%, and 17% in 4 of 5 severe renal trauma V analyzed. CONCLUSION: Among the 21 children managed for a severe kidney trauma injury IV or V, 11 required a therapeutic procedure, one of them a nephrectomy. The DMSA scintigraphy performed after at least 6 months from the trauma found an injured renal function at 39.4% in 11 of 16 severe renal trauma IV analyzed, and 17% in 4 of 5 severe renal trauma V analyzed, which confirms the currently conservative management. LEVEL OF EVIDENCE: Type of study: original article, retrospective observational study, level IV.

OBJECTIVE: To evaluate the current place of robotics in laparoscopic urological surgery. MATERIAL AND METHODS: A review of the international literature was conducted to evaluate the various available endoscope robot systems and telemanipulator robots and to establish their practical limitations and their contribution to surgery. RESULTS: Robotic systems are based on various structures, which each present specific disadvantages. Two types of systems can be distinguished: endoscope robots and telemanipulator robots (complete robotic systems) with different degrees of complexity, dimensions and costs. Each system is different in terms of service rendered. Endoscope robot systems (EndoAssist, AESOP, LapMan) are reliable and eliminate the need for an assistant to hold the camera. Man-machine interfaces can be manual, by pedal or by voice recognition. They are relatively large and expensive, limiting their diffusion at the present time. Complete instrument-handling robots (master-slave manipulators) are currently represented by 2 robots (Zeus and Da Vinci) which have demonstrated their efficacy in many difficult operations. Their very high cost and their large dimensions also constitute limitations to their diffusion, making them inaccessible to the majority of centres. The urological community has largely contributed to the evaluation of robots in laparoscopic operations, as reflected by the large number of publications. CONCLUSION: Considerable technological progress has been made over recent years to make laparoscopic surgery more accessible. Current robotized tools are still imperfect systems, but, in the future, may possibly facilitate difficult laparoscopic operations, particularly in urology.

OBJECTIVE: The objective of this study is to assess the results of our therapeutic management of blunt kidney trauma in patients hospitalised over the last 10 years. MATERIALS AND METHODS: From January 1993 to January 2003, 105 patients were hospitalised in our department for blunt kidney trauma. We retrospectively studied age, gender, injured side, mechanism of trauma (direct, indirect or deceleration), aetiology, presence of associated lesions (visceral, orthopaedic), and clinical and laboratory signs on admission (haematuria, blood pressure, haemoglobin and serum creatinine). The grade of the lesions was defined by radiological assessment, specifying the presence or absence of devascularized fragments and urine extravasation. All complications were noted and studied according to the initial therapeutic management and grade. Follow-up was clinical (BP and search for renal pain) and radiological (CT and/or DMSA scan). RESULTS: 105 cases of blunt trauma of the kidney were hospitalised between January 1993 and January 2003 in our department. The mean age of the patients was 28.7 years (range: 7-75 years). Trauma was classified into 5 grades on the basis of the radiological assessment according to the ASST (American Society of Surgery of Trauma): 51 (49%) cases of grade 1 (n = 26) and grade 2 (n = 25) trauma, and 54 (51%) cases of major grade 3 to 5 trauma: 17 grade 3 (16%), 28 grade 4 (27%) and 9 grade 5 (8%) were diagnosed. Among the cases of major trauma, 7 (13%) were operated urgently during the first 24 hours: 4 cases of grade 5 trauma with renal artery dissection and 3 cases of grade 4 trauma with immediate uncontrolled bleeding. The nephrectomy rate (partial and total), when major renal trauma (grade 3, 4 and 5) (n = 47) was managed conservatively was 23% (11 nephrectomies) with the loss of 9.5 renal units (20%); this rate was 57% for grade 4 trauma presenting urine extravasation and devascularized fragments (n = 14). Twelve patients (7 with grade 4 trauma and 5 with grade 3 trauma) were reviewed by DMSA scintigraphy with a mean follow-up of 63 months (range: 26-108 months). Traumatized kidneys presented a mean function of 41.8% (range: 26.4-50%). CONCLUSION: Blunt kidney trauma is usually managed conservatively. The development of interventional radiology, endourological drainage techniques and medical intensive care helps to maintain this attitude by decreasing the need for surgery, even in the most severe trauma.

The authors report a case of leiomyoma of the renal capsule. Although leiomyoma is a frequent tumour in the uterus, leiomyomas of the urinary tract are very rarely reported in the literature. This tumour has an excellent prognosis. In rare cases, the diagnosis may be suggested by CT scan, but histological examination confirms the diagnosis of benign tumour.

OBJECTIVES: Lesions of the renal pedicle after blunt trauma of the abdomen are rare, and the results of the various therapeutic approaches are unpredictable and usually disappointing. We therefore decided to evaluate an endovascular approach with stent placement in this indication. CASE: A 50-year-old woman, after jumping out of a window, arrived in coma with multiple organ lesions, haemorrhagic shock and initial haemodynamic instability. Renal arteriography, performed 2 hours after the fall, showed complete dissection of the right renal artery. A stent was inserted. Revascularization was satisfactory on follow-up CT. The macroscopic haematuria initially present rapidly resolved. With a follow-up of 1 month, the kidney presented a normal morphology with a normal nephrogram and a normal excretion time. CONCLUSION: In renal pedicle trauma, urgent elective nephrectomy in patients with a functional contralateral kidney now appears to be the most widely used treatment option, regardless of the interval since trauma. Treatment by vascular stent can be performed even in the context of serious multiple injuries, and the first attempts show encouraging results.

OBJECTIVE: To determine the tolerance of prostate biopsies in the case of co-administration of an analgesic gas composed of a ready for use mixture of nitrogen monoxide and oxygen (MEOPA) (marketed under the trade name of Kalinox), and intrarectal instillation of xylocaine gel by comparing the results with those obtained in a control group only receiving intrarectal xylocaine instillation. MATERIAL AND METHODS: Non-randomized, prospective study conducted on 100 cases, with a control group composed of the first 22 patients (before availability of MEOPA in the department), followed by 78 patients treated with MEOPA. A questionnaire was completed by the patient and by the outpatient nurse caring for the patient. RESULTS: A very significant reduction (p=0.003) of the VAS pain score (from 3.86 to 2.38) and a highly significant improvement (p<0.001) of global tolerance of the procedure based on the nurse's estimation of pain (VAS scale) were observed. The MEOPA group also presented a significant improvement of pain in patients who had previously undergone a series of prostate biopsies (p=0.043). The satisfaction rate was higher in patients receiving MEOPA, although 28.2% of patients experienced adverse effects, all minor and bothersome in only 3.81% of cases. CONCLUSION: The MEOPA analgesic method as a complement to intrarectal xylocaine instillation considerably improved tolerance of the procedure with no major adverse effects and without prolonging the procedure or the surveillance. It is simple to use, safe and effective.

The current management of blunt trauma of the kidney is based on the 5-grade classification of lesions established by the ASST (American Society of the Surgery of Trauma). The indications for imaging are now clearly defined and spiral CT represents the reference examination. Over the last decade, the debate concerning the management of severe trauma has divided the supporters of surgical treatment from those who recommended conservative management. The contribution of interventional radiology and endourological treatments and the efficacy of intensive care now limit the complications related to trauma and reduce the need for surgery. However, the morbidity related to trauma is considerable in the presence of fragments of devascularized renal parenchyma, urine extravasation and associated lesions. These complications can be anticipated by a better definition of the traumatic lesions. The American classification presents certain limitations in relation to these combinations of poor prognostic factors. This review was designed to define the most recent biomechanical considerations, the place of imaging and finally the indications and results of management of blunt trauma of the kidney, in the light of the data of the literature.

Mixed epithelial and stromal tumour of the kidney (MESTK) is a rare kidney neoplasm that occurs almost exclusively in perimenopausal women. Long-term oestrogen replacement appears to play a major role in its pathogenesis. Around 70 cases have been described in the international literature, none of which involve male children. Herein, we describe an atypical case of MESTK diagnosed in a 12-year-old prepubertal boy who presented with hematuria. Pathology and immunohistochemistry revealed a typical MESTK. The child was free of disease at 2-year follow up after a partial nephrectomy and tumour excision.
