Barriers for pregnancy and perceptions of gender discrimination of urologists in training in France: Results of a National Survey.

INTRODUCTION: Gender discrimination seems more prevalent in surgery than other medical specialties. In addition, female urologists are more likely to have obstetric complications and to be discouraged from starting a family during training. The objective of this study was to determine the prevalence of perceived gender discrimination and barriers for pregnancy during fellowship, among French urology residents and fellows. MATERIAL AND METHODS: The French Association of Urologists in Training performed a national online survey between August and September 2022. Participants were assured that their participation was anonymous. Respondents were questioned on demographics, gender discrimination and on pregnancy barriers during fellowship. RESULTS: 153 members answered the questionnaire out of the 427 members of the association (36%), among which 75 women (49%). Thirty nine percent of the female respondents found that their gender was a barrier in their career advancement, versus 1% of the male (p<0.0001). Forty female respondents (53%) perceived that female urologists earned less respect than their male counterparts versus 22% of the male (p<0.0001). Among the female respondents, 19 (25%) have felt that it would not be possible to become pregnant at the time they would have wanted it and 7 (9%) reported having already been threatened to lose a fellowship position in case of a pregnancy. CONCLUSION: This survey found a high prevalence of gender discrimination among French urologists in training, perceived in majority by women. Female urologists perceived obstacles and received threats when wanting to become pregnant during their training.

Carboplatin and Etoposide for the Treatment of Metastatic Prostate Cancer with or without Neuroendocrine Features: A French Single-Center Experience.

BACKGROUND: Chemotherapy using carboplatin and etoposide (CE) is frequently pragmatically proposed to treat metastatic prostate cancer (mPC), both primary small-cell neuroendocrine (PSC-NE) carcinoma and adenocarcinoma with or without neuroendocrine (NE) marker elevation. However, the real benefit of CE is poorly reported in the recent therapeutic context. METHODS: We retrospectively analyzed the efficacy and tolerance of CE chemotherapy in these three different groups of mPC patients. Efficacy endpoints included radiological response, progression-free survival (PFS), and overall survival (OS), as well as PSA response and PFS2/PFS1 ratio in patients with adenocarcinoma. RESULTS: Sixty-nine patients were included in this single-center study (N = 18 with PSC-NE carcinoma and 51 with adenocarcinoma with (N = 18) or without (N = 33) NE marker elevation). Patients with adenocarcinoma were highly pretreated with next-generation hormonal agents (NHAs) and taxanes. In patients with adenocarcinoma, a PSA response ≥50% was observed in six patients (15.8%), four of whom had NE marker elevation. The radiological response was higher in PSC-NE and tended to be higher in adenocarcinoma when NE marker elevation was present. Comparing patients with adenocarcinoma with vs. without NE marker elevation, the median PFS was 3.7 and 2.1 months and the median OS was 7.7 and 4.7 months, respectively. Overall, 62.3% of patients experienced grade 3-4 adverse events (mainly hematological), and three treatment-related deaths were recorded. CONCLUSION: Reports of the clinical results of CE suggest that we should not mix PSC-NE and castration-resistant adenocarcinoma of the prostate. In patients with heavily pretreated adenocarcinoma, the benefit/risk ratio of CE chemotherapy seems unfavorable due to poor response and high toxicity.

Cut-off time for surgery and prediction of orchiectomy in spermatic cord torsion: a retrospective multicentric study over 15 years.

PURPOSE: Cut-off time to avoid orchiectomy relies on small series of patients. The objective was to determine the cut-off time to avoid orchiectomy in torsion of the spermatic cord in a large cohort. METHODS: We performed a retrospective multicenter study (TORSAFUF cohort) of patients with suspected spermatic cord torsion between 2005 and 2019. All patients aged > 12 years who were suspected of having a torsion of the spermatic cord in 14 University Hospitals in France were included (n = 2986). Patients for whom data on pain duration were not available (n = 923) or for whom the final diagnosis was not torsion of the spermatic cord (n = 807) were excluded. The primary outcome was orchiectomy. The secondary outcomes were testicular survival time and the prediction of orchiectomy with the duration of pain. RESULTS: 1266 patients were included with an orchiectomy rate of 12% (150 patients). The mean age was 21.5 years old in the salvage group and 23.7 years old in the orchiectomy group (p = 0.01), respectively. The median time from the onset of pain to surgery was 5.5 (IQR = 5) hours in the salvage group and 51.1 (IQR = 70) hours in the orchiectomy group (p < 0.0001). The risk of orchiectomy increased after a time cut-off of 6 h 30. A delay of 15 h 30 in pain duration was found to predict orchiectomy (sensitivity: 0.81; specificity: 0.87). CONCLUSIONS: Pain duration can predict the probability of salvaging the testicles and performing orchiectomy. Rapid intervention should be recommended, regardless of the time elapsed from the onset of pain.

Role of magnetic resonance imaging for preoperative prediction of early biochemical failure in localized prostate cancer.

Background: The purpose of our study was to assess preoperative clinical biological and Magnetic Resonance Imaging (MRI) predictive factors of early biochemical failure (BF), defined as persistence of significant post-operative plasmatic prostate specific antigen (PSA) level after radical prostatectomy (RP) in patients with localized prostate cancer (PCa). Methods: In a retrospective cohort study we included 142 patients from our university hospital with newly diagnosed PCa, who underwent 3T multiparametric MRI prior to RP. Only the MRI target lesions [Prostate Imaging Reporting and Data System (PIRADS) ≥3] with histological correspondence were considered significant. Clinical, biological, MRI and pathological preoperative data were studied. We performed univariate and multivariate logistic regression analysis to identify significant parameters associated with early BF. Results: Early BF occurred in 14% of patients (20/142). Patients with BF had higher PSA level at diagnosis, Gleason score, number of positive biopsies, size of the largest positive biopsy and higher National Comprehensive Cancer Network (NCCN) risk score (P<0.001 for all). According to MRI, they also had higher T stage and a higher size of capsular contact (P<0.001 for all). In contrast, there was no difference concerning neither ADC value, perfusion profile and zonal location of the index lesion. In multivariate analysis, the best combination of predictive factors of early BF was the association of preoperative Gleason score ≥4+3 [odds ratio (OR) =6.8 (1.4-32.5); P=0.002] and T stage ≥3 on preoperative MRI [OR =17.4 (3.2-94.9); P<0.001] with an area under the curve (AUC) of 0.89 [99% confidence interval (CI): 0.77-1], a negative predictive value of 94% and a positive predictive value of 75%. Conclusions: Combination of simple preoperative biomarkers as Gleason score and T stage according to MRI accurately stratify the risk of early BF following RP. These results emphasize the pivotal role of preoperative MRI for the management of localized PCa.

Climate-smart Actions in the Operating Theatre for Improving Sustainability Practices: A Systematic Review.

CONTEXT: Surgical activity contributes to global warming though the production of greenhouse gases and consumption of resources. To date, no clinical practice guidelines have been made to promote and implement climate-smart actions. OBJECTIVE: To perform a systematic review of the available actions that could limit CO2 emission in the operating room (OR) and their potential benefits upon the environment, whilst preserving quality of care. EVIDENCE ACQUISITION: MEDLINE and Cochrane databases were searched from January 1, 1990 to April 2021. We included studies assessing carbon footprint (CF) in the OR and articles detailing actions that limit or reduce CF. EVIDENCE SYNTHESIS: Thirty-eight studies met the inclusion criteria. We identified six core climate-smart actions: (1) waste reduction by segregation; (2) waste reduction by recycling, reuse, and reprocessing; (3) sterilisation; (4) anaesthesia gas management; and (5) improvement of energy use. Quantitative analysis regarding the CF was not possible due to the lack of homogeneous data. For climate-smart actions, the analysis was limited by discrepancies in study scope and in the methodology of CO2 emission calculation. Improvement of education and awareness was found to have an important impact on waste segregation and reduction. Waste management is the area where health care workers could have the strongest impact, whereas the main field to reduce CF in the OR was found to be energy consumption. CONCLUSIONS: This review provides arguments for many climate-smart actions that could be implemented in our daily practice. Improving awareness and education are important to act collectively in a sustainable way. Further studies are mandatory to assess the impact of these climate-smart actions in the OR. PATIENT SUMMARY: We performed a systematic review of the available scientific literature to reference all the climate-smart actions proposed to improve the sustainability of surgical activities. Waste segregation, waste reduction and recycling, reuse and reprocessing, sterilisation, anaesthesia gas changes, and improvement of energy use in the operating room were found to be the main areas of research. There is still a long way to go to homogenise and improve the quality of our climate-smart actions.

Prediction of prostate cancer recurrence after radiation therapy using multiparametric magnetic resonance imaging and spectroscopy: assessment of prognostic factors on pretreatment imaging.

Background: To assess whether data from pre-therapeutic multiparametric magnetic resonance imaging (mpMRI) combined with three-dimensional magnetic resonance spectroscopy (3D MRS) provide prognostic factors of biochemical relapse in patients with localized prostate cancer treated by external radiotherapy or brachytherapy. Methods: In our single institution observational retrospective study we included a cohort of 230 patients treated by external radiotherapy or brachytherapy who had an initial mpMRI with 3D MRS from January 2008 to December 2015 for newly diagnosed localized prostatic cancer, proven histologically. Three trained radiologists recorded tumor characteristics, MRI T-stage and metabolic abnormalities from 3D MRS data. Univariate and multivariate Cox analyzes explored the relationship between clinical and imaging variables to highlight prognostic factors for recurrence, using biochemical relapse as the primary endpoint. Results: mpMRI data analysis allowed to reclassify 21.7% of the patients in a MRI National Comprehensive Cancer Network (NCCN) group higher than their initial clinical T-stage, but also to detect a lesion in 78% of the patients considered as clinically T1c. After a median of follow-up of 8.7 years (IQR, 6.6-10.1) following cancer diagnosis, 36 (16%) patients developed a biochemical relapse. The multivariate Cox analysis demonstrated the existence of 3 independent factors for prediction of biochemical recurrence: extracapsular extension (ECE) (HR =3.33; 95% CI: 1.93-5.73; P<0.01), choline/citrate ratio in healthy tissue in the transition zone (TZ) (HR =2.96; 95% CI: 1.06-8.28; P=0.04) and the NCCN Magnetic Resonance Imaging classification (intermediate versus low-risk, HR =3.06; 95% CI: 1.13-8.30; P<0.01). Conclusions: Combination of mpMRI and 3DMRS could aid in the prognostic stratification of localized prostate cancer treated by radiotherapy or brachytherapy, by combining accurate evaluation of tumor extension, and quantification of prostate metabolism.

Torsion of the spermatic cord in adults: a multicenter experience in adults with surgical exploration for acute scrotal pain with suspected testicular torsion.

Acute scrotal pain (ASP) requiring surgical exploration is common in the pediatric population, but little has been reported on this subject with regard to the adult population. The aim of this study was to investigate the demographic and clinical characteristics and outcomes of scrotal explorations performed on adult patients. Patients over 21 years of age who underwent surgical exploration for ASP with suspected testicular torsion (TT) at 14 French hospitals between January 2005 and December 2019 were included in this study. The main outcome measures were demographic characteristics, pathology found during scrotal exploration, and perioperative outcomes. Logistic regression was used to perform univariate and multivariate analyses to identify predictors of TT. Data for 1329 men were analyzed. The median age was 30 (interquartile range [IQR]: 25-35; range: 21-89) years. Regarding the clinical examination, 867 (65.2%) patients presented with an elevation of the testicle, 613 (46.1%) patients with scrotal edema or erythema, and 211 (15.9%) patients with nausea or vomiting. Operative findings identified TT in only 684 (51.5%) patients, epididymo-orchitis in 112 (8.4%) patients, a tumor in 16 (1.2%) patients, and no causes in 475 (35.7%) patients. Orchiectomy for nonviable testes was required in 101 (7.6%) patients. In multivariate analysis, an elevation of the testicle, erythema/swelling, and the presence of nausea/vomiting were found to be associated with the occurrence of TT. Testicular torsion is not exclusive to children and adolescents, so must be considered in males of any age with acute scrotal findings. However, one-third of scrotal explorations in adults did not lead to a diagnosis.

The Use of Doppler Ultrasound for Suspected Testicular Torsion: Lessons Learned from a 15-Year Multicentre Retrospective Study of 2922 Patients.

BACKGROUND: Use of Doppler ultrasonography (DUS) for patients with suspected testicular torsion (TT) is highly controversial and remains debated, as it can delay surgery and its performance may vary. OBJECTIVE: To assess the role, impact, safety, and performance of DUS in the management of patients with suspected TT before scrotal exploration. DESIGN, SETTING, AND PARTICIPANTS: The TORSAFUF cohort retrospectively included patients older than 12 yr who underwent surgery for suspected TT in 14 academic hospitals between 2005 and 2019. Perioperative data and surgical and DUS reports were collected. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Clinical factors influencing DUS utilisation were analysed using multivariate logistic regression. The orchidectomy rate and delay to surgery were compared by group with and without DUS receipt using one-to-one propensity score (PS) matching to assess imaging safety. For the group with preoperative imaging, DUS performance was evaluated using a contingency table. RESULTS AND LIMITATIONS: Overall, 2922 patients were included, of whom 956 (32.7%) underwent DUS before surgery. DUS was more likely to be performed in older patients (odds ratio [OR] 1.1, 95% confidence interval [CI] 1.1-1.2), those who experienced progressive onset of pain (OR 1.5, 95% CI 1.1-2), and patients who presented at the emergency department more than 6 h after their first scrotal symptoms (OR 2.3, 95% CI 1.9-2.8). After PS matching, DUS receipt was not significantly associated with orchidectomy but the delay to surgery was 1 h longer. DUS demonstrated strong sensitivity of 85.2% (95% CI 82.1-88.3%) and specificity of 52.7% (95% CI 48.8-56.6%). The performance was better for younger patients and for those with time since onset of pain of >6 h. CONCLUSIONS: In this large retrospective study, DUS before surgery was safe, feasible, and useful in selected cases with suspected TT, but it should not delay or replace surgery in cases with a strong clinical suspicion. PATIENT SUMMARY: We analysed the performance and safety of an ultrasound scan of the scrotum before surgery for patients with a suspected twisted testicle (TT). This scan before surgery was not associated with a higher risk of negative outcomes but was only moderate in accurately diagnosing TT. Surgery to correct TT should not be delayed.

[Pedagogical impact of a MOOC on surgical technique of kidney transplantation]. / Impact pédagogique d'un MOOC de technique chirurgicale de transplantation rénale.

OBJECTIVE: To evaluate the educational impact of a pilot MOOC (Massive Open Online Course), validated by the French College of Urology Teachers (FCUT), on the surgical technique of kidney transplantation. MATERIALS AND METHODS: We developed a MOOC on the surgical technique of kidney transplantation, based on a video of a surgical procedure, performed by an expert surgeon. The MOOC has been validated by the FCUT. We have created 2 student groups: 1) MOOC-pre-QCM group: visualization of the MOOC then answer to the MCQs and satisfaction questions; 2) MOOC-post-QCM group: answer to the MCQs then visualization of the MOOC then answers to the satisfaction questions. In total, 20 MCQs on the kidney transplantation technique were completed by the 2 groups. The answers were anonymous. RESULTS: A total of 142 people answered the MCQs (MOOC-pre-QCM group (n=66) and MOOC-post-QCM group (n=76)). Twenty-nine percent (41/142) of the participants were fellows and 71 % (101/142) were residents. The proportion of fellows and residents was identical between the 2 groups. The rate of correct answers to the 20 MCQs was statistically higher in the MOOC-pre-QCM group, compared to the MOOC-post-QCM group (88.6 % versus 73.3 %, P<0.0001). Ninety-one percent of students found the MOOC "Very Useful" or "Useful". The median MOOC rating, given by students, was 8/10. CONCLUSION: This study showed a positive impact of the MOOC on theoretical knowledge of kidney transplantation surgical technique. This MOOC could serve as a pilot project for the development of other MOOCs on urological surgery. LEVEL: 3.

Automatic Evaluation of Histological Prognostic Factors Using Two Consecutive Convolutional Neural Networks on Kidney Samples.

BACKGROUND AND OBJECTIVES: The prognosis of patients undergoing kidney tumor resection or kidney donation is linked to many histologic criteria. These criteria notably include glomerular density, glomerular volume, vascular luminal stenosis, and severity of interstitial fibrosis/tubular atrophy. Automated measurements through a deep-learning approach could save time and provide more precise data. This work aimed to develop a free tool to automatically obtain kidney histologic prognostic features. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: In total, 241 samples of healthy kidney tissue were split into three independent cohorts. The "Training" cohort (n=65) was used to train two convolutional neural networks: one to detect the cortex and a second to segment the kidney structures. The "Test" cohort (n=50) assessed their performance by comparing manually outlined regions of interest to predicted ones. The "Application" cohort (n=126) compared prognostic histologic data obtained manually or through the algorithm on the basis of the combination of the two convolutional neural networks. RESULTS: In the Test cohort, the networks isolated the cortex and segmented the elements of interest with good performances (>90% of the cortex, healthy tubules, glomeruli, and even globally sclerotic glomeruli were detected). In the Application cohort, the expected and predicted prognostic data were significantly correlated. The correlation coefficients r were 0.85 for glomerular volume, 0.51 for glomerular density, 0.75 for interstitial fibrosis, 0.71 for tubular atrophy, and 0.73 for vascular intimal thickness, respectively. The algorithm had a good ability to predict significant (>25%) tubular atrophy and interstitial fibrosis level (receiver operator characteristic curve with an area under the curve, 0.92 and 0.91, respectively) or a significant vascular luminal stenosis (>50%) (area under the curve, 0.85). CONCLUSION: This freely available tool enables the automated segmentation of kidney tissue to obtain prognostic histologic data in a fast, objective, reliable, and reproducible way.

Three-dimensional nuclear magnetic resonance spectroscopy: a complementary tool to multiparametric magnetic resonance imaging in the identification of aggressive prostate cancer at 3.0T.

BACKGROUND: The limitations of the assessment of tumor aggressiveness by Prostate Imaging Reporting and Data System (PI-RADS) and biopsies suggest that the diagnostic algorithm could be improved by quantitative measurements in some chosen indications. We assessed the tumor high-risk predictive performance of 3.0 Tesla (3.0T) multiparametric magnetic resonance imaging (mp-MRI) combined with nuclear magnetic resonance spectroscopic sequences (NMR-S) in order to show that the metabolic analysis could bring out an evocative result for the aggressive form of prostate cancer. METHODS: We conducted a retrospective study of 26 patients (mean age, 62.4 years) who had surgery for prostate cancer between 2009 and 2016 after pre-therapeutic assessment with 3.0T mp-MRI and NMR-S. Groups within the intermediate range of the D'Amico risk classification were divided into two categories, low risk (n=20) and high risk (n=6), according to the International Society of Urological Pathology (ISUP) 2-3 limit. Histoprognostic discordances within various risk groups were compared with the corresponding predictive MRI values. The performance of predictive models was assessed based on sensitivity, specificity, and the area under the curve (AUC) of receiver operating characteristic (ROC) curves. RESULTS: After prostatectomy, histological analysis reclassified 18 patients as high-risk, including 16 who were T3 MRI grade, of whom 13 (81.3%) were found to be pT3. Among the patients who had cT1 or cT2 digital rectal examinations, the T3 MRI factor multiplied by 8.7 [odds ratio (OR), 8.7; 95% confidence interval (CI), 1.3-56.2; P=0.024] the relative risk of being pT3 and by 5.8 (OR, 5.8; 95% CI, 0.95-35.7; P=0.05) the relative risk of being pGleason (pGS) > GS-prostate biopsy. Spectroscopic data showed that the choline concentration was significantly higher (P=0.001) in aggressive disease. CONCLUSIONS: The predictive model of tumor aggressiveness combining mp-MRI plus NMR-S was better than the mp-MRI model alone (AUC, 0.95 vs. 0.86). Information obtained by mp-MRI coupled with spectroscopy may improve the detection of occult aggressive disease, helping in the discrimination of intermediate risks.

Contralateral Orchiopexy at the Time of Urgent Scrotal Exploration-Is It Safe? A Propensity Score Matched Analysis from the TORSAFUF Cohort.

PURPOSE: We evaluate the safety of immediate contralateral orchiopexy (ICLO) at the time of scrotal exploration for testicular torsion suspicion. MATERIALS AND METHODS: Patient data were retrieved from the TORSAFUF cohort project, which is a multicenter national study conducted at 14 academic French hospitals between 2005 and 2019. Each patient who underwent surgical exploration for testicular torsion suspicion was included. The primary study outcome was the safety of ICLO compared to ipsilateral scrotal exploration alone. The primary outcome of interest was the complication rate within 90 days of surgery. The end point was planned before data collection. RESULTS: Overall, 2,775 patients were included, of whom 1,554 (56%) underwent ICLO. After propensity score matching and multivariable analysis, ICLO was associated with a higher complication rate (OR 1.51, 95% CI 1.1-2.1, p=0.01), especially a higher rate of hematoma (OR 2.9, 95% CI 1.3-6.6, p=0.01), and delayed wound healing (OR 3.0, 95% CI 1.8-5.2, p <0.001). CONCLUSIONS: At the time of scrotal exploration for acute scrotum, ICLO was associated with an increased postoperative complication rate, with a particular increase in hematoma, and delayed wound healing. ICLO should not be performed systematically.

Retrospective study on the management and follow-up of 18 patients with a mid-urethral sling penetrating the urethra or bladder.

INTRODUCTION: The mid-urethral sling (MUS) procedure is the gold-standard for the surgical treatment of stress urinary incontinence (SUI). Urethro-vesical sling exposure is one of the most serious complications of this procedure. We describe the treatment and follow-up of 18 patients with bladder or urethral sling exposure. PATIENTS AND METHODS: This single-center, retrospective study assessed the diagnosis and management of MUS penetrating the lower urinary tract in 18 women. The lesions included were classed as 4B, T3-4, S3 according to the international classification of complications related to the insertion of prostheses. Diagnosis was confirmed by flexible urethro-cystoscopy. The patients were treated surgically. In all cases, the aim was to remove all synthetic materials eroding the bladder or urethra. The patients were reassessed 6 weeks after the procedure, and functional urologic sequelae were treated. Urologic symptoms were evaluated using the USP questionnaire and urologic comfort was assessed using the Contilife questionnaire. RESULTS: Seven MUSs were retro-pubic and 11 were trans-obturators. The material was 11 polypropylene macroporous monofilament, four polypropylene silicone coated and three non-available. There were six cases of urethral sling exposure, nine cases of bladder sling exposure, and three cases of urethral and bladder sling exposure, including five complicated cases of lithiasis and one urethra-vaginal fistula. Thirteen patients underwent one surgical procedure, four underwent two, and one underwent five procedures. Seven patients received a Martius flap. Three surgical approaches were necessary: (i) vaginal approach; (ii) urologic (urethral and suprapubic) cystoscopy approach; and (iii) laparoscopy approach. Median follow-up time was 34.5 months. At the end of follow-up, 17/18 patients had no sling exposure from the MUS, and 12/13 patients were considered comfortable from a functional urologic viewpoint. CONCLUSION: Our study showed that surgery could treat urethro-vesical sling exposure. Three surgical approaches may be necessary. Controlled cystoscopy is vital to confirm healing due to the recurrences of sling exposure in our study.
