Management of high-grade papillary Ta or T1 bladder cancer after restaging transurethral resection: A retrospective study comparing Bacillus Calmette-Guerin therapy upfront versus a third resection.

PURPOSE: Performing restaging transurethral bladder resection (reTURB) for high-risk non-muscle invasive bladder cancer (NMIBC) reduces the risk of recurrence and tumour understaging. Management of residual high-grade papillary Ta or T1 after reTURB has changed this last 10years in international recommendations. This study aimed to compare the recurrence free survival according to the different management procedures performed. MATERIALS AND METHODS: Patients who underwent reTURB for initial high-risk NMIBC between 2011 and 2020 were included. Patients with residual high-grade papillary Ta or T1 tumour after reTURB were divided into two groups: BCG instillations upfront versus BCG following a third-look resection (3TURB). Patient and tumour characteristics, BCG instillations, recurrence-free survival were retrospectively analysed. RESULTS: A total of 162 high-risk patients were included. Sixty-one (37.7%) had residual high-grade papillary Ta or T1 at reTURB: 35 (21.6%) had BCG instillations upfront, 18 (11.2%) had a 3TURB and 8 (5%) had other management. The mean follow-up was 34.2weeks±20.2. Recurrence-free survival was significantly better in patients who underwent BCG instillations upfront (P<0.0043). Recurrence after BCG therapy following reTURB was significantly lower in patients with no residual NMIBC at 6 (92.5% vs. 72.4%, P<0.004) and 12months (85% vs. 67.3%, P<0.03). CONCLUSIONS: The efficacy of intravesical BCG is compromised in case of residual tumour following TURB. The role of a 3TURB following a positive reTURB is not yet determined. This study has confirmed that residual tumor following reTURB is a negative predictive factor but could not demonstrate the value of a 3TURB compared to upfront BCG.

[Complications in urological surgery: Monitoring and classification]. / Les complications en chirurgie urologique. Recueil et classification.

The objective of this article was to discuss the statistics of surgical complications in urology and the methods of collection and classification. In the absence of a comprehensive national registry of complications, we used statistics from insurance companies as indicators. They are limited by the exclusion of complications that did not result in a claim. Overall, urology is less exposed to claims than other surgical specialties. It comes far behind orthopedic surgery, gynecology-obstetrics and visceral surgery. The new techniques in urological surgery and in particular the rise of robotic surgery do not seem to have modified the number of claims handled by medical insurance companies. It is unfortunate that complications in urological surgery are not collected, reported, and discussed in order to develop prevention, treatment, and strategies for educational purposes. The lack of an established definition and classification of surgical complications, as well as methodological differences in the collection of related information, has hampered the evaluation of their public health and health economics impact. Awareness of this problem is growing among learned societies and practitioners. Complication reporting should be organized on a national basis and should respect the following points: - definition of the collection process according to a validated system. For urology, the Martin table revised by the EAU working group would be adapted; - classification of complications according to a validated system such as Clavien-Dindo or CCI.

[Complications of radical nephrectomy and partial nephrectomy: What are they? How can they be anticipated and managed?] / Les complications de la néphrectomie totale et de la néphrectomie partielle : quelles sont-elles, comment les prévenir et les prendre en charge ?

INTRODUCTION: Surgical techniques of radical and partial nephrectomy have changed over the last 20years. Indications for partial nephrectomy have widened and mini-invasive surgery (laparoscopy and robotic assistance) has become widely used. However, both still have a significant morbidity. The objective of this article is to review complications of renal surgery and their predictive factors and to offer algorithms of management. METHODS: Recent literature regarding complications of radical and partial nephrectomy was queried using Pubmed engine search. The most relevant articles were analyzed and served as a basis for this work. RESULTS: The literature on complications of radical and partial nephrectomy has a low level of evidence. There are only retrospective series. The most frequent complications of radical nephrectomy occur during surgery in 5-10% of the cases: wound of the pedicle or of an adjacent organ. The management can often be conservative. Laparoscopy has a similar morbidity compare to the open approach but has greatly increased postoperative outcomes and comfort. Partial nephrectomy has a 20% complication rate. Many factors have an impact on the risk of complications (tumor size, inflammation of perirenal fat, access, surgeon experience, centre volume, comorbidities and age of the patient) and must be taken into consideration before advising partial nephrectomy. The two most feared complications of partial nephrectomy are bleeding (per- or postoperative, 10% of the cases) and urinary fistula (<5% of the cases). Robotic assistance is associated with a lower morbidity in many publications. CONCLUSION: Complications after partial and radical nephrectomy are quite frequent but have decreased with the improvement of surgical techniques. French urologists should maintain their interest in novel technologies and simplification of perioperative pathway to further improve patients' outcomes.

[Complications in urological surgery. Prevention]. / Complications chirurgicales en urologie adulte. La prévention.

The objective of this article was to summarize the means and tools of prevention and safety of care to reduce non-random surgical complications in urology, related to the care environment and the patient. The prevention of complications is an essential strategy to be applied in a standardized way in urological surgery, as in the world of aeronautics, from which we can draw valuable lessons. This prevention is multifactorial and concerns interventions, systems and human factors. The essential points listed below must be traceable: the quality of the assessment of the patient and his co-morbidities. This is a multidisciplinary task; the relevance of the surgical indication, which must take into account the state of the art at the time it is given; the expertise of the urologist and his continuing education; the relevance of the surgical indication, which must take into account the state of the art at the time it is given; the quality of the information provided to the patient and his family, and to the medical and paramedical team involved in the patient's care; the quality of the professional environment and equipment; compliance with recommended safety rules (e.g. checklist, identity check). All these points are not isolated but interdependent. They must be recorded in the patient's file, the quality and completeness of which is essential to the patient's follow-up, to the prevention and management of complications and to the understanding, if necessary, of the truth of the medical facts.

[Complications in urological surgery: Bladder surgery]. / Les complications chirurgicales en urologie adulte : chirurgie de la vessie.

CONTEXT-OBJECTIVE: The management of bladder tumors is based on two major interventions, the risks of complications of which can be significant. The objective of this work is to provide an update on the complications related to bladder surgery, to detail the preventive measures and management strategies in practice. METHODS: Bibliographic search using Medline bibliographic database (Pubmed) using the following keywords: transurethral resection of the bladder, cystectomy, neobladder, Bricker, complications, anastomotic strictures. RESULTS: Trans-urethral resection of the bladder (TURB) essentially exposes to the risk of hemorrhage (2 to 4%) and bladder perforation (1 to 3%). Total cystectomy is associated with significant morbidity and mortality, despite recent technical advances. The most frequent early complications are ileus (23 to 30%) and infectious complications (29 to 38%). Late complications included by functional complications (urinary and sexual), anastomotic strictures (7 to 12%), metabolic complications of continent derivation (25 to 46%) and stomial complications in case of non-continent derivation. The management of complications is well codified. It is however essential to anticipate and put in place preventive measures, especially for infectious and thromboembolic complications, including an exhaustive pre-operative assessment, prehabilitation of the patient and enhanced recovery after surgery. CONCLUSION: Preventing, analyzing and understanding complications in bladder surgery is essential to reduce mortality and morbidity.

[Complications in urological surgery: Prostate surgery]. / Les complications chirurgicales en urologie adulte : chirurgie de la prostate.

Prostate surgery mainly addresses the treatment of the two most common pathologies of the prostate: benign prostatic hypertrophy (BPH), symptomatic or complicated, and prostate cancer (PCa). The objective of this manuscript was to present after review of the literature the main intraoperative and postoperative surgical complications associated with radical prostatectomy and surgery of the BPH whatever the surgical approach. The incidence and type of these complications may vary depending on the patient's comorbidities and the type of surgery. Regarding radical prostatectomy, the main complications are hemorrhagic, digestive and urinary. During or after surgery of BPH, hemorrhagic and urinary complications dominate. The management of these complications relies on general principles based on a low level of evidence, but usually associate a structured diagnostic pathway and an appropriate treatment decision.

[Complications in endourology: Ureteroscopy and percutaneous nephrolithotomy]. / Complications en endo-urologie : urétéroscopie et néphrolithotomie percutanée.

If surgical treatment of urinary stones is indicated, the urologist has now different modalities depending on each situation. This includes extracorporeal lithotripsy, ureteroscopy (rigid and flexible), and percutaneous nephrolithotomy. Ureteroscopy is also performed for diagnostic purposes, and for the treatment of upper urinary tract tumors. Indications, as well as the steps of each of these techniques will not be discussed in this review. Only intra- and postoperative complications of ureteroscopy and percutaneous nephrolithotomy will be reviewed, including diagnostic, management, and preventive measures.

[Surgical complications in adult urology: Pelvic and perineal surgery]. / Les complications chirurgicales en urologie adulte : chirurgie du pelvis et du périnée.

Pelvic and perineal surgeries and in particular those for stress urinary incontinence and prolapse are functional surgeries, which require careful selection of patients and assessment of discomfort to expect satisfactory surgical results and reduce failure rates and of complications. Before offering pelvic and perineal surgery, the risk of potential complications should be carefully assessed and discussed with patients. Recent attention to the potential complications prosthetic mesh has raised awareness in the urological community to report complications. This chapter will focus on the complications of surgeries used for stress urinary incontinence (synthetic retropubic or transobturator suburethral slings, colposuspension, pubovaginal slings, artificial urinary sphincter, adjustable periurethral balloons and periurethral injections of bulking agents) and sacrocolpopexies. The epidemiology of complications, the minimum assessment to be carried out, treatment and prevention will be discussed.

[Surgical complications in adult urology: Surgery of the external genitalia]. / Les complications chirurgicales en urologie adulte : chirurgie des organes génitaux externes.

AIM: Define and present the complications of surgery of the external genitalia (EG), as well as their management. METHOD: Bibliographic search using the Medline (NLM Pubmed tool) and Embase bibliographic databases using the following keywords: scrotal surgery, orchidopexy, hydrocele, varicocele, testicular biopsy, vasectomy, cryptorchidism, orchiectomy, testicular implant, subcapsular orchiectomy, spermatic cord cyst, posthectomy, penis curvature surgery, penile implant, urethral strictures. RESULTS: EG surgery is common in urology, it includes scrotal surgeries and penile surgeries, which are performed openly. They expose to complications such as bleeding, infection, scar disunity requiring early reassessment especially in case of ambulatory procedure. Rare complications must be known, some of which must lead to expert management. CONCLUSION: Complications of surgical treatment of EG should be identified and managed. This report should allow a better understanding and management of these complications.

[Complications in urological surgery. The urologist as a player in risk management]. / Les complications en chirurgie urologique. L'urologue acteur de la gestion des risques.

The first part of this article deals with accreditation of the quality of the professional practice of urologists and medical teams working in public or private health care institutions. This is a voluntary national risk management process based on the reporting and analysis of medical risk events and the development and implementation of recommendations. The fundamental objective of the system is to reduce the frequency and severity of adverse events associated with care for the patient. The second part aims to describe the mechanisms and management of surgical complications. The perception of complications by the urologist is discussed, as it may be distorted by cognitive biases leading to inappropriate actions. Two important points were also emphasized: communication with the patient following an injury, therapeutic hazard or complication following an error, and proper maintenance of the medical record. A joint effort to cultivate a culture of safety and quality in urological surgical practice should be encouraged. Collective actions by urologists in the future should help to maintain a proactive attitude: - generalization of quality accreditation of urologic physicians' professional practice; - national registry: which has demonstrated its advantages in the world of aeronautics; - creation of a specific module "Management of complications in urology" in teaching (ECU) and continuing education (SUC, website); - creation of an AFU "Complications" Committee; - management of social networks.

[Assessment of positive surgical margins in the management of patients after radical prostatectomy for pT2 prostate cancer]. / Impact des marges chirurgicales positives après prostatectomie radicale chez les patients atteints d'un cancer de la prostate localisé pT2.

INTRODUCTION: Few data are available regarding positive surgical margins (PSM) in patients who underwent surgery for localized prostate cancer (PC). Our objective was to evaluate the impact of PSM on biochemical recurrence-free survival (BRFS) for patients who underwent PC for pT2 tumor without adjuvant treatment. METHODS: We included each patient who underwent radical prostatectomy for pT2N0 PC between 1988 and 2018. Primary endpoint was biochemical recurrence (BR). BRFS was calculated using Kaplan-Meier method. Univariate and multivariate analyses were used to determine factors associated with BR and PSM. RESULTS: Overall, 2429 patients were included whom 420 patients had PSM (17.3%). Median follow-up was 116 months. BRFS at 10 years was 66.6% in case of PSM, and 84% in the negative margins group (P<0.0001). Parameters associated with BR were preoperative PSA level (P<0.0001), Gleason score (P<0.0001), tumor volume in biopsies, and margins length (P<0.04). CONCLUSION: PSM in pT2N0 CP are associated with poor prognosis in terms of BR. Nevertheless, only a small number of pT2R1 cancer will present biological recurrence. The use of adjuvant radiotherapy in these patients therefore represents a risk of overtreatment, with the risk of adverse effects inherent to irradiation. Clinical and biological monitoring in case of PSM seems acceptable.

[Radical prostatectomy in patients with Gleason 6 (ISUP 1) prostate cancer: 10-year follow-up]. / Recul à 10 ans des patients opérés pour un cancer de prostate Gleason 6 (ISUP1).

OBJECTIVE: To evaluate extraprostatic extension and 10 years cancer specific survival in a population of patients with Gleason 6 (ISUP 1) prostate cancer (PCa) treated by radical prostatectomy (RP) in two French third referral centers. MATERIALS AND METHODS: The data were extracted from 2 university hospital databases according to the following criteria: PCa classified ISUP 1 following both biopsy (PB) and surgery (RP) between 1998 and 2008. Pathology slides of patients having presented an extraprostatic extension and/or a recurrence were reviewed by a uropathologist. RESULTS: Among the 534 patients who met the inclusion criteria, 66 (12.2%) had a pT3 stage. One patient out of 198 who received lymph node dissection had a positive node. Median follow-up was 10.3 years. Only one patient presented with metastatic progression. No cancer specific death was observed. An independent pathologist reviewed the slides of 58 out of the 70 patients who presented pT3 disease and/or a recurrence (in 12 cases, pathological material was not available). After review, all pT3b stages and 12 pT3a (out of 14) were upgraded to ISUP2 or higher. Similarly, the patient with a positive node and the patient who progressed towards a metastatic disease were both upgraded to ISUP 3. CONCLUSION: No pT3b or pN+stage was associated with ISUP 1 PCa in our study. With a median follow-up of more than 10 years, biological progression was the only type of progression observed.

Risk factors for residual disease at re-TUR in a large cohort of T1G3 patients.

INTRODUCTION AND OBJECTIVES: The goals of transurethral resection of a bladder tumor (TUR) are to completely resect the lesions and to make a correct diagnosis in order to adequately stage the patient. It is well known that the presence of detrusor muscle in the specimen is a prerequisite to minimize the risk of under staging. Persistent disease after resection of bladder tumors is not uncommon and is the reason why the European Guidelines recommended a re-TUR for all T1 tumors. It was recently published that when there is muscle in the specimen, re-TUR does not influence progression or cancer specific survival. We present here the patient and tumor factors that may influence the presence of residual disease at re-TUR. MATERIAL AND METHODS: In our retrospective cohort of 2451 primary T1G3 patients initially treated with BCG, pathology results for 934 patients (38.1%) who underwent re-TUR are available. 74% had multifocal tumors, 20% of tumors were more than 3 cm in diameter and 26% had concomitant CIS. In this subgroup of patients who underwent re-TUR, there was no residual disease in 267 patients (29%) and residual disease in 667 patients (71%): Ta in 378 (40%) and T1 in 289 (31%) patients. Age, gender, tumor status (primary/recurrent), previous intravesical therapy, tumor size, tumor multi-focality, presence of concomitant CIS, and muscle in the specimen were analyzed in order to evaluate risk factors of residual disease at re-TUR, both in univariate analyses and multivariate logistic regressions. RESULTS: The following were not risk factors for residual disease: age, gender, tumor status and previous intravesical chemotherapy. The following were univariate risk factors for presence of residual disease: no muscle in TUR, multiple tumors, tumors > 3 cm, and presence of concomitant CIS. Due to the correlation between tumor multi-focality and tumor size, the multivariate model retained either the number of tumors or the tumor diameter (but not both), p < 0.001. The presence of muscle in the specimen was no longer significant, while the presence of CIS only remained significant in the model with tumor size, p < 0.001. CONCLUSIONS: The most significant factors for a higher risk of residual disease at re-TUR in T1G3 patients are multifocal tumors and tumors more than 3 cm. Patients with concomitant CIS and those without muscle in the specimen also have a higher risk of residual disease.

[Single, immediate postoperative intra-vesical instillation (SI) compared to a single preoperative intra-vesical instillation of mitomycin C in non-muscle invasive bladder cancer (NMIBC). Phase II randomized trial]. / Instillation préopératoire immédiate (IPOI) de mitomycine C comparée à l'instillation postopératoire précoce (IPOP) dans les tumeurs de la vessie. Étude de phase II randomisée.

OBJECTIVE: A single immediate instillation of mitomycin C is recommended after a complete transurethral resection of the bladder (TURB) in low- and intermediate-risk patients with NMIBC. Actually, post-TURB instillation is seldom used due to logistical difficulties and surgical contraindications. Our aim was to compare patients with single pre-TURB intra-vesical instillation and patients with a single, immediate post-TURB intra-vesical instillation of mitomycin C. METHODS: We performed a multicenter randomized trial between February 17, 2014 and November 24, 2016 (registration number 2012-004341-32). Sixty patients with two or less, primary or recurrent papillary bladder tumors and a negative urinary cytology were planned. Cystoscopy was performed at 3, 6 and 12 months after TURB. Our primary endpoint was disease-free interval. Secondary endpoints were recurrence rate at 3 and 12 months, rate of patients in whom instillation could not be performed and tolerance 1 month after TURB using BCI-Fr score. RESULTS: Among 35 eligible participants, 20 were randomly assigned in the pre-TURB instillation group and 15 in the post-TURB instillation group. Follow-up was comparable: 12,3±1,6 months in the SI group and 10,2±4,5 months in the pre-TURB instillation group. In the post-TURB instillation group, 2 patients didn't have any instillation. We did not identify significant differences in disease-free interval. Tolerance at 1 month after TURB was similar in both groups. CONCLUSION: Tolerance and efficacy were not significantly different. As expected, logisitics were easier for the health providers in the pre-TURB group where all patients had their instillation conversely to the post-TURB group. These results suggest that the advantages of a single immediate pre-TURB instillation warrant further evaluation of this strategy in a phase III randomized trial.

[Impact of the COVID-19 pandemic on surgical activity within academic urological departments in Paris]. / Impact de la pandémie de COVID-19 sur l'activité chirurgicale au sein des services d'urologie de l'Assistance Publique ­ Hôpitaux de Paris.

INTRODUCTION: As a result of the COVID-19 pandemic in France, all non-emergency surgical activity has been cancelled since March 12, 2020. In order to anticipate the reinstatement of delayed interventions, surgical activity reduction analysis is essential. The objective of this study was to evaluate the reduction of urological surgery in adult during the COVID-19 pandemic compared to 2019. MATERIAL: The data regarding urological procedures realized in the 8 academic urological departments of Parisians centres (AP-HP) were compared over two similar periods (14-29 March 2019 and 12-27 March 2020) using the centralized surgical planning software shared by these centres. Procedure title, type of surgery and outpatient ratio were collected. The interventions were sorted into 16 major families of urological interventions. RESULTS: Overall, a 55% decrease was observed concerning urological procedures over the same period between 2019 and 2020 (995 and 444 procedures respectively). Oncology activity and emergencies decreased by 31% and 44%. The number of kidney transplantations decreased from 39 to 3 (-92%). Functional, andrological and genital surgical procedures were the most impacted among the non-oncological procedures (-85%, -81% and -71%, respectively). Approximatively, 1033 hours of surgery have been delayed during this 16-day period. CONCLUSION: Lockdown and postponement of non-urgent scheduled urological procedures decisions has led to a drastic decrease in surgical activity in AP-HP. Isolated kidney transplantation has been stopped (national statement). Urologists must anticipate for lockdown exit in order to catch-up delayed surgeries. LEVEL OF EVIDENCE: 3.

[Indocyanine green fluorescence to visualize the ureteric vascularization of kidney transplants: An exploratory study]. / Visualiser la vascularisation urétérale des transplants rénaux par fluorescence au vert d'indocyanine : étude exploratoire.

INTRODUCTION: Urinary complications after kidney transplantation are common and can compromise renal function. While they are mainly attributed to ischemic lesions of the ureter, there is no existing method to evaluate its vascularization during surgery. The aim of the study was to evaluate if indocyanine green, revealed by infra-red light andused to visualize tissue perfusion, could provide an appreciation of the ureter's vascularization during kidney transplantation. METHODS: This feasibility study was conducted over one month, on eleven consecutive kidney transplants. During transplantation, an injection of indocyanine green enabled the surgeon to visualize in real time with an infra-red camera the ureter fluorescence. Its intensity was reported on a qualitative and semi-quantitative scale. Occurrence of urinary complications such as stenosis or ureteral fistula were collected during 6 months. RESULTS: In all of the 11 cases (100%), the last centimeters of the ureters were not fluorescent. Three (27%) ureters were poorly or partiallly fluorescent. Out of these three cases, only one case of urinary fistula occurred, followed by ureteric stenosis. In the series, two fistulas (18%) and two ureteric stenoses (18%) occurred. No side effects were observed. The low number of events did not allow statistical analysis. CONCLUSION: Infra-red fluorescence of indocyanine green could be a simple and innovative way to appreciate the transplant's ureteric vascularization during kidney transplantation. It could help surgeons to identify the level of ureter section and to decide the anastomosis technique, in order to limit urinary complications. LEVEL OF EVIDENCE: 3.

[Is sarcopenia a morbi-mortality factor in the treatment of localized muscle-invasive bladder cancer?] / La sarcopénie est-elle un facteur de morbi-mortalité dans le traitement des tumeurs localisées de la vessie infiltrant le muscle ?

INTRODUCTION: Sarcopenia evaluated from the measurement of skeletal muscle index (SMI) has been evaluated as a predictive factor of morbidity and mortality after surgery. The objective of this study was to evaluate whether it was predictive of morbidity and mortality in patients managed by cystectomy or tri-modality therapy (TMT), combining radiotherapy and chemotherapy after endoscopic resection of the tumour, for localized muscle-invasive bladder cancer. MATERIALS AND METHODS: In all, 146 consecutive patients from 2 university hospital centres treated by cystectomy between January 2012 and April 2017 or TMT between October 2008 and October 2014 were included. The SMI was measured on axial computed-tomography at the level of the transverse process of L3, before treatment. Sarcopenia was assessed in two ways: either by SMI without muscle mass adjustment or according to the definition by Martin and al. based on gender and patient BMI, then called "adjusted sarcopenia". The primary endpoint was overall survival (OS) for sarcopenia. The secondary endpoints were OS, progression-free survival (PFS) and survival without re-admission (SRH) for the total population and for each treatment group. Survival analyses were performed using the Cox model. The association between sarcopenia and complications has been investigated by the Chi2 test. RESULTS: The characteristics of sarcopenic (n=67) and non-sarcopenic (n=79) patients were comparable except for 2 criteria: older patients in the sarcopenic group and a higher proportion of neo-adjuvant chemotherapy in non-sarcopenic patients. Sarcopenia was not significantly associated with any type of survival. Sarcopenia was not associated with the proportion or severity of complications. CONCLUSION: Unlike unadjusted SMI, sarcopenia was not associated with survival or complications. LEVEL OF EVIDENCE: 3.

[Is it necessary to perform urine culture systematically prior to double J ureteral stent removal?] / Est-il nécessaire de faire systématiquement un ECBU avant l'ablation d'une sonde double J ?

OBJECTIVE: To assess the value of systematic urine culture before ureteric double j removal. MATERIAL AND METHODS: This prospective audit was performed to assess the validity of our current clinical practice. A cohort of informed patients without clinical signs of urinary tract infection and without predefined risk factors were programmed for ureteral double j stent removal in an outpatient setting. Urine was sampled for culture immediately before the procedure. Patients had to complete a self-questionnaire 15 days following stent removal, inquiring about tolerance and complications which were to be analyzed according to the culture results. The primary endpoint was the occurrence of febrile urinary tract infection. RESULTS: Among the 56 participants, immediate preoperative urine culture revealed colonization in 9 patients (16.1%) and contamination in 6 patients (10.7%). A significant association was found between bacteriuria and double j placement following surgery with urinary tract injury (P<0.02) and diabetes (P<0.009). Two patients had fever including a man with sterile urine and a woman with Staphylococcus Aureus infection. No hospitalization was necessary. Twelve patients reported functional signs with lumbar pain being the most common. There was no significant association between functional signs and patients' clinical characteristics. CONCLUSION: This evaluation was not in favor of modifying our protocol of care i.e. the lack of performing neither antibiotic prophylaxis nor systematic urine culture before JJ ureteral stent removal in a selected population. LEVEL OF EVIDENCE: 4.

[Prognostic value of testosterone during androgene deprivation therapy]. / Valeur pronostique de la testostéronémie lors de l'hormonothérapie intermittente du cancer de la prostate.

INTRODUCTION: The concept of intermittent androgen deprivation therapy (IADT) for prostate cancer (PCa) was introduced in order to improve treatment tolerance with the same carcinological efficiency as continuous androgen deprivation therapy (CADT). Furthermore, studies have shown that PCa prognosis during CADT was correlated to the extent of testosterone collapse. The aim of this study was to assess the link between testosterone levels at the end of the first off-treatment phase and time to occurrence of castrate-resistant prostate cancer. METHODS: We retrospectively analyzed the files of 69 patients having undergone IADT. Intermittence was offered to the patients showing PSA<4ng/mL after at least six months of androgen deprivation therapy (ADT) using a LHRH analog. CRPC was defined according to the AFU oncological guidelines. Patients were sorted into three groups according to their testosterone levels at the end of the first off-treatment phase T<0.5ng/mL, 0.53.4ng/mL. CRPC free-survival, metastasis-free survival and overall survival as well as adverse events frequency were compared between the groups. The impact of initial ADT duration on CRPC occurrence, mean off-treatment phase duration and IADT duration was also studied. RESULTS: Testosterone levels at the end of the first and second off-treatment phases were not linked to time to CRPC occurence (p=0.5), mestastasis occurence (p=0.4) or death (p=0.3). It was associated neither with adverse effects frequency (p=0.2) nor with cancer-related complications (p=0.6). Initial ADT duration was not linked to CRPC occurrence (p=0.6), mean off-treatment phase duration (p=0.5) or mean IADT duration (p=0.6). CONCLUSION: This study did not show any link between testosterone levels at the end of the first off-treatment phase (before reintroducing ADT) and overall survival, metastasis-free survival and CRPC-free survival. Likewise, it was not associated with the frequency of adverse events or cancer-related complications. Initial ADT duration was not linked to CRPC occurrence or IADT chronological parameters.
