Standardized one-day evaluation before urinary reconstructive surgery for neurogenic lower urinary tract dysfunction: Feasibility and impact on surgical strategy and care pathway. Prog Urol 2023; 33:1014-1025. [PMID: 37858377 DOI: 10.1016/j.purol.2023.09.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 09/16/2023] [Accepted: 09/26/2023] [Indexed: 10/21/2023]
Abstract
OBJECTIVES To describe a concept of standardized preoperative one-day evaluation before urinary reconstructive or diversion surgery for the treatment of neurogenic lower urinary tract (LUT) dysfunction, and to evaluate its feasibility and its impact on the care pathway. MATERIALS AND METHODS All patients who underwent a one-day standardized evaluation before a urinary reconstructive or derivation surgery for the treatment of neurogenic LUT dysfunction between January 2017 and December 2021 in our institution were included. Data were collected retrospectively from standardized reports. The main outcome was the rate of completion of the tests and consultations planned during this evaluation. Secondary outcomes included the findings from the one-day evaluation and changes in the urological surgical strategy at different time points within one year. RESULTS One hundred and thirty-one patients benefited from this one-day standardized evaluation. The overall completeness rate of the data collected was 77.5%, increasing from 62.3% in 2017 to 89.3% in 2021. The urological surgical plan was modified for 19.1% of patients following this preoperative evaluation. The indication was then confirmed for 114 patients (87.0%) by the multidisciplinary meeting and was carried out unchanged during the following year for 89 patients (67.9%). An associated colostomy procedure was proposed for 18.3% of patients and was finally performed in 11.5%. CONCLUSION A standardized multidisciplinary preoperative one-day evaluation before performing reconstructive or diversion surgery for the treatment of neurogenic LUT dysfunction seems feasible and makes it possible to optimize the surgical plan and adapt the course of care.

Abstract
INTRODUCTION Firearm injuries to the lower urinary tract are injuries resulting from an energy transfer from a projectile fired by a firearm or a blast from a firearm, to the bladder, prostate, urethra and terminal ureter. Our objective was to describe the epidemiological and diagnostic aspects in the context of a security crisis. PATIENTS AND METHOD This was a descriptive cross-sectional study of lower urinary tract firearm injuries at Sominé Dolo Hospital in Mopti from January 2017 to December 2021. RESULTS In five years, 29 traumas of the lower urinary tract have been collected, about 6 cases per year. The mean age of patients was 27.48 years, the sex ratio was 13.5/1. The main circumstances of occurrence were intercommunal violence 51.72 %, war wounds 31.03 %. Injuries were inflicted by rifles in 62.1 % and improvised explosive devices in 37.9 %. The main modes of discovery were acute urine retention, hematuria and penoscrotal wounds respectively in 31.03 %, 20.69 %, 17.24 %. The organs affected were the urethra in 58.62 %, the bladder, 37.93 %, the prostate 3.45 %. Associated non-urological lesions present in 68.96 % (n=20) were dominated by intestinal lesions and pelvic fractures. CONCLUSION Firearm injuries to the lower urinary tract are rare despite the context of the security crisis. They affect young men, are mostly linked to intercommunal violence, and are dominated by urethral and bladder injuries.

Functional MRI in neuro-urology: A narrative review. Prog Urol 2023:S1166-7087(23)00082-9.

Abstract
Neuro-imaging has given urologists a new tool to investigate the neural control of the lower urinary tract. Using functional magnetic resonance imaging (fMRI), it is now possible to understand which areas of the brain contribute to the proper function of the storage and voiding of the lower urinary tract. This field of research has evolved from simple anatomical descriptions to elucidating the complex micturition network. A keyword search of the Medline database was conducted by two reviewers for relevant studies from January 1, 2010, to August 2022. Of 2047 peer-reviewed articles, 49 are included in this review. In the last decade, a detailed understanding of the brain-bladder network has been described, elucidating a dedicated network, as well as activated areas in the brainstem, cerebellum, and cortex that share reproducible connectivity patterns. Research has shown that various urological diseases can lead to specific changes in this network and that therapies used by urologists to treat lower urinary tract symptoms (LUTS) are also able to modify neuronal activity. This represents a set of potential new therapeutic targets for the management of the lower urinary tract symptoms (LUTS). fMRI technology has made it possible to identify subgroups of responders to various treatments (biofeedback, anticholinergic, neuromodulation) and predict favourable outcomes. Lastly, this breakthrough understanding of neural control over bladder function has led to treatments that directly target brain regions of interest to improve LUTS. One such example is the use of non-invasive transcranial neuromodulation to improve voiding symptoms in individuals with multiple sclerosis.

[Guidelines on the urological management of the adult patient with spinal dysraphism (spina bifida)]. Prog Urol 2023; 33:178-197. [PMID: 36609138 DOI: 10.1016/j.purol.2022.12.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2022] [Accepted: 12/10/2022] [Indexed: 01/06/2023]
Abstract
INTRODUCTION Improved life expectancy and prenatal screening have changed the demographics of spina bifida (spinal dysraphism) which has presently become a disease of adulthood. Urinary disorders affect almost all patients with spinal dysraphism and are still the leading cause of mortality in these patients. The aim of this work was to establish recommendations for urological management that take into account the specificities of the spina bifida population. MATERIALS AND METHODS National Diagnosis and Management Guidelines (PNDS) were drafted within the framework of the French Rare Diseases Plan at the initiative of the Centre de Référence Maladies Rares Spina Bifida - Dysraphismes of Rennes University Hospital. It is a collaborative work involving experts from different specialties, mainly urologists and rehabilitation physicians. We conducted a systematic search of the literature in French and English in the various fields covered by these recommendations in the MEDLINE database. In accordance with the methodology recommended by the authorities (Guide_methodologique_pnds.pdf, 2006), proposed recommendations were drafted on the basis of this literature review and then submitted to a review group until a consensus was reached. RESULTS Bladder dysfunctions induced by spinal dysraphism are multiple and varied and evolve over time. Management must be individually adapted and take into account all the patient's problems, and is therefore necessarily multi-disciplinary. Self-catheterisation is the appropriate micturition method for more than half of the patients and must sometimes be combined with treatments aimed at suppressing any neurogenic detrusor overactivity (NDO) or compliance alteration (anticholinergics, intra-detrusor botulinum toxin). Resort to surgery is sometimes necessary either after failure of non-invasive treatments (e.g. bladder augmentation in case of NDO resistant to pharmacological treatment), or as a first line treatment in the absence of other non-invasive alternatives (e.g. aponeurotic suburethral tape or artificial urinary sphincter for sphincter insufficiency; urinary diversion by ileal conduit if self-catheterisation is impossible). CONCLUSION Spinal dysraphism is a complex pathology with multiple neurological, orthopedic, gastrointestinal and urological involvement. The management of bladder and bowel dysfunctions must continue throughout the life of these patients and must be integrated into a multidisciplinary context.

Abstract
OBJECTIVE To update the CCAFU recommendations for the management of muscle invasive bladder carcinoma (MIBC). METHODS A systematic review (Medline) of the literature from 2020 to 2022 was performed taking account of the diagnosis, treatment options and surveillance of NMIBC and MIBC, while evaluating the references with their levels of evidence. RESULTS MIBC is diagnosed after the most complete tumour resection possible. MIBC grading is based on CTU along with chest CT. Multiparametric pelvic MRI could be an alternative. Cystectomy with extensive lymphadenectomy is the gold standard treatment for non-metastatic MIBC. It should be preceded by platinum-based neoadjuvant chemotherapy in patients in good general health with satisfactory renal function. Enterocystoplasty is proposed in men and women in the absence of contraindications and when the urethral resection is negative on extemporaneous examination. Otherwise, transileal cutaneous ureterostomy is the recommended method of urinary diversion. Inclusion of all patients in an ERAS (Enhanced Recovery After Surgery) protocol is recommended. For metastatic MIBC, first line treatment with platinum-based chemotherapy (GC or MVAC) is recommended, if general health (PS>1) and renal function (clearance>60mL/min) so allow (only 50% of the cases). Pembrolizumab immunotherapy has demonstrated an overall survival benefit in second-line treatment. CONCLUSION Updating the ccAFU recommendations should contribute to improving patient management, as well as the diagnosis and decision-making concerning MIBC treatment.

Abstract
OBJECTIVE To update the ccAFU recommendations for the management of bladder tumours that do not infiltrate the bladder muscle (NBMIC). METHODS A systematic review (Medline) of the literature from 2020 to 2022 was performed, taking account of the diagnosis, treatment options and surveillance of NMIBC, while evaluating the references with their levels of evidence. RESULTS The diagnosis of NMIBC (Ta, T1, CIS) is made after complete full-thickness tumour resection. The use of bladder fluorescence and the indication of a second look (4-6 weeks) help to improve the initial diagnosis. The EORTC score is used to assess the risk of recurrence and/or tumour progression. Through the stratification of patients in low, intermediate and high-risk categories, adjuvant treatment can be proposed: intravesical chemotherapy (immediate postoperative, initiation regimen) or BCG (initiation and maintenance regimen) instillations, or even the indication of cystectomy for BCG-resistant patients. CONCLUSION Updating the ccAFU recommendations should contribute to improving patient management, as well as the diagnosis and treatment of NMIBC.

Abstract
OBJECTIVE - To update French guidelines for the management of bladder cancer specifically non-muscle invasive (NMIBC) and muscle-invasive bladder cancers (MIBC). METHODS - A Medline search was achieved between 2018 and 2020, notably regarding diagnosis, options of treatment and follow-up of bladder cancer, to evaluate different references with levels of evidence. RESULTS - Diagnosis of NMIBC (Ta, T1, CIS) is based on a complete deep resection of the tumor. The use of fluorescence and a second-look indication are essential to improve initial diagnosis. Risks of both recurrence and progression can be estimated using the EORTC score. A stratification of patients into low, intermediate and high risk groups is pivotal for recommending adjuvant treatment: instillation of chemotherapy (immediate post-operative, standard schedule) or intravesical BCG (standard schedule and maintenance). Cystectomy is recommended in BCG-refractory patients. Extension evaluation of MIBC is based on contrast-enhanced pelvic-abdominal and thoracic CT-scan. Multiparametric MRI can be an alternative. Cystectomy associated with extended lymph nodes dissection is considered the gold standard for non-metastatic MIBC. It should be preceded by cisplatin-based neoadjuvant chemotherapy in eligible patients. An orthotopic bladder substitution should be proposed to both male and female patients with no contraindication and in cases of negative frozen urethral samples; otherwise transileal ureterostomy is recommended as urinary diversion. All patients should be included in an Early Recovery After Surgery (ERAS) protocol. For metastatic MIBC, first-line chemotherapy using platin is recommended (GC or MVAC), when performans status (PS <1) and renal function (creatinine clearance >60 mL/min) allow it (only in 50% of cases). In second line treatment, immunotherapy with pembrolizumab demonstrated a significant improvement in overall survival. CONCLUSION - These updated French guidelines will contribute to increase the level of urological care for the diagnosis and treatment of patients diagnosed with NMIBC and MIBC.

Evaluation of margins in pelvic lymph nodes and prostate radiotherapy and the impact of bladder and rectum on prostate position. Cancer Radiother 2021; 25:161-168. [PMID: 33454191 DOI: 10.1016/j.canrad.2020.06.033] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2019] [Revised: 06/29/2020] [Accepted: 06/30/2020] [Indexed: 10/22/2022]
Abstract
PURPOSE The aims of this study were: determination of the CTV to PTV margins for prostate and pelvic lymph nodes. Investigation of the impact of registration modality (pelvic bones or prostate) on the CTV to PTV margins of pelvic lymph nodes. Investigation of the variations of bladder and rectum over the treatment course. Investigation of the impact of bladder and rectum variations on prostate position. PATIENTS AND METHODS This study included 15 patients treated for prostate adenocarcinoma. Daily kilo voltage images and weekly CBCT scans were performed to assess prostate displacements and common and external iliac vessels motion. These data was used to calculate the CTV to PTV margins using Van Herk equation in the setting of a daily bone registration. We also compared the CTV to PTV margins of pelvic lymph nodes according to registration method; based on pelvic bone or prostate. We delineated bladder and rectum on all CBCT scans to assess their variations over treatment course at 4 anatomic levels [1.5cm above pubic bone (PB), superior edge, mid- and inferior edge of PB]. RESULTS Using Van Herk equation, the prostate CTV to PTV margins (bone registration) were 8.03mm, 5.42mm and 8.73mm in AP, ML and SI direction with more than 97% of prostate displacements were less than 5mm. The CTV to PTV margins ranged from 3.12mm to 3.25mm for external iliac vessels and from 3.12mm to 4.18mm for common iliac vessels. Compared to registration based on prostate alignment, bone registration resulted in an important reduction of the CTV to PTV margins up to 54.3% for external iliac vessels and up to 39.6% for common iliac vessels. There was no significant variation of the mean bladder volume over the treatment course. There was a significant variation of the mean rectal volume before and after the third week of treatment. After the third week, the mean rectal volume seemed to be stable. The uni- and multivariate analysis identified the anterior wall of rectum as independent factor acting on prostate motion in AP direction at 2 levels (superior edge of, mid PB). The right rectal wall influenced the prostate motion in ML direction at inferior edge of PB. The bladder volume tends toward significance as factor acting on prostate motion in AP direction. CONCLUSIONS We recommend CTV to PTV margins of 8mm, 6mm and 9mm in AP, ML and SI directions for prostate. And, we suggest 4mm and 5mm for external and common iliac vessels respectively. We also prefer registration based on bony landmarks to minimize bowel irradiation. More CBCT scans should be performed during the first 3weeks and especially the first week to check rectum volume.

Abstract
INTRODUCTION Second look TURB (Transurethral Resection of Bladder Tumor) is recommended for high-risk pT1 tumors. It is well acquired for tumors classified pT1 high grade but its interest is still discussed for high-grade pTa tumors in the absence of high level of evidence. We evaluated the impact of second-look resection for the high-grade pTa bladder tumor. METHODS We performed a retrospective study in 2 centers from 2007 to 2016. We included all urothelial tumors classified pTa high grade. We studied the anatomopathological findings of reTURB and its consequences on survival without recurrence and progression. RESULTS Eighty-four patients were included. Thirty-five patients (41.7%) had reTURB and residual tumor was found in 42.9% of cases. The anatomopathology of reTURB was in 20% of cases high grade pTa, in 14.3% of cases pTis, and in 8.6% of cases pT1. Forty-three patients had recurrence, 13 reTURB patients (30.2%). In the patients who had a reTURB, 12 had recurrence (34.3%) against 31 without reTURB, (63.3%). After the first TURB, 45 patients (53.6%) had bladder instillation: 38 received BCG (45.2%) and 7 ametycin (8.3%). The main factor decreasing recurrence was BCG adjuvant therapy (HR=0.4 [0.2-0.9], P=0.02). The absence of reRTUV appeared to be a recurrence factor, but the result was not statistically significant (HR=1.4 [0.7-3], P=0.3). CONCLUSION reTURB confirms that residual tumor is often found. His interest in survival without recurrence remains to be proved by a prospective study with a larger number of patients. LEVEL OF EVIDENCE 3.

Abstract
Wolfram syndrome is a neurodegenerative disorder characterized by childhood onset diabetes mellitus, optic nerve atrophy, diabetes insipidus, hearing impairment, brainstem alteration and commonly bladder and bowel dysfunction. OBJECTIVE We present here, 6 new cases of urinary dysfunction in this rare disease. RESULTS All patients had urinary retention with overactive bladder. The urodynamic assessment found overactive detrusor in 3 cases. Five out of six patients performed self-catheterization and were treated with anticholinergics or intradetrusor injection of botulinum toxin. The follow-up at 5 years found an alteration of the upper urinary tracts and a renal failure 3/6. CONCLUSION Urinary dysfunction is common in Wolfram syndrome, mainly characterized by overactive bladder and urinary retention. The urological risk is major requiring a systelmatic follow-up of these patients. LEVEL OF EVIDENCE 4.

Abstract
When localized, the reference treatment of urothelial, muscle-invasive bladder tumours relies on radical cystectomy with reconstruction by enterocystoplasty if possible or Bricker bypass. Trimodal therapy combining transurethral resection of the tumour followed by concomitant chemotherapy may be considered as a therapeutic alternative to radical cystectomy in well-selected patients with unifocal tumours, stage T2, non-diverticular location, without in situ carcinoma or hydronephrosis and with macroscopically complete transurethral resection. The functional prognosis of the bladder and quality of life should be discussed with the patient as well as the need for salvage surgery for persistent tumour at a 45-Gy dose level, the latter being a highly unfavourable prognosis factor. On the other hand, this trimodal treatment is the reference in case of surgical contraindication. This article details the methods and results of the main series available in the literature in terms of local control, survival, bladder preservation rates and complications, as well as study prospects.

Abstract
As for the Bethesda system for cervical and thyroid cytopathology, a terminology for reporting urinary cytology has been published in 2015. The new "Paris System" provides a consensus terminology for urinary cytology which underlines the criteria for the recognition of high-grade urothelial carcinoma (HGUC) and of those excluding HGUC, or suspicious for HGUC. It also focuses on new rules to recognize and report the subgroup of "atypical urothelial cells". Here we describe and illustrate the various categories as in the reference book. We analyse the main diagnostic criteria, including microscopic features as well as the risk of malignancy associated to every diagnostic category.

Abstract
Neuroendocrine small cell carcinoma of the bladder is a rare and aggressive tumour, accounting for less than 1% of all bladder tumours. Given its rarity and the absence of randomized trials, the therapeutic management of these tumours remains difficult. By analogy with small cell lung cancer, multimodal treatment is often proposed. Radical cystectomy plus chemotherapy and chemoradiation therapy are associated with better survival compared to monotherapy. We report our experience in the management of these tumours with literature review.

Abstract
INTRODUCTION Bladder tumor is a disease of older persons, but can also occur in young adults, because certainly an influence of environmental factors and a change of lifestyle. The aim of our retrospective analysis is to assess and evaluate the extent of the prognostic impact of age on the carcinological prognosis of invasive-muscle-bladder cancer treated by total cystotomy. METHODS To evaluate the association of patient age with pathological characteristics and recurrence-free and disease survival, we retrospectively reviewed 345 patients with invasive bladder cancer between January 2000 and January 2015. RESULTS We divided our patients into two groups: patients under 65 years of age=150 cases (group 1), patients aged 65 years and over=195 cases (group 2). The 3-year survival rates for patients according to the age groups were 88% and 64% respectively, end the recurrence-free survival 66% and 28%. When age was analysed as a categorical variable, was associated with hydronephrosis (P=0.001), advanced pathological stage (P=0.034), high grade (P=0.026), nodal involvement (P=0.011) and lymphovascular invasion (P=0.008). The multivariate Cox model analysis showed that hydronephrosis and pathological stage was prognostic factors of survival (P=0.012 and P=0.035, respectively). Higher age is significantly associated with the risk of pathologically advanced disease and poorer global survival. CONCLUSION This work allowed us to assert that advanced chronological age is significantly associated with an advanced pathological stage of the disease (volume, pT, grade, lymph nodes) and a low overall survival rate. This could be useful for selecting subjects who would require adjuvant therapy, as well as for planning early complementary therapies. LEVEL OF EVIDENCE 3.

Abstract
Bladder dose constraints in case of conformational radiotherapy/intensity-modulated radiotherapy and stereotactic radiotherapy are reported from the literature, in particular from the French radiotherapy society RECORAD recommendations, according to the treated pelvic tumor sites. The dose-volume effect on urinary toxicity is not clearly demonstrated, making difficult to establish absolute dose constraints for the bladder. In case of high-dose prostate cancer radiotherapy, the bladder dose constraints are: V60Gy<50% and maximum dose<80Gy for standard fractionation and V60Gy<5%, V48Gy<25% and V41Gy<50% for moderate hypofractionation (20 fractions of 3Gy). In case of prostate stereotactic radiotherapy (five fractions of 7.25Gy), the most frequent dose constraints in the literature are V37Gy<10cm3 and V18Gy<40%. In case of conformational radiotherapy of cervix cancer, postoperative endometrium, anal canal and rectum, the recommendations are V40Gy<40% and D2% lower than the prescribed dose.

Abstract
Urothelial tumors are very rare in children (to date, only about 150 cases have been reported worlwide). Only 20% occur before the age of ten. The aim of this study is to specify the clinicopathologic features of urothelial tumor in young patients, which require a slightly different approach to treatment. On the basis of the WHO/ISUP (World Health Organisation/International Society of Urological Pathology) consensus classification report, these lesions are usually low-grade lesions, non invasive, and rarely recurrent. The sex ratio is three boys to one girl. These tumors are located preferentially in the low urinary tract, especially in the bladder. The main symptom is the macroscopic hematuria, which requires ultrasound examination in all cases. Cystoscopy is indicated in case of lesion of the bladder wall, or in case of persistent or recurrent hematuria, to obtain definitive diagnosis and biopsies. The tumors are mainly located on the posterior or lateral bladder wall above the trigone or near the ureteral orifices. Treatment is based on the transurethral resection of the lesion. The subsequent monitoring is sparsely codified, due to the exceptional occurrence of these tumors in the paediatric age group. These patients are likely to have better outcome than older patients, but it is due to the predominance of noninvasive papillary urothelial tumors. Tumor recurrences are not uncommon. In case of invasive, high-grade urothelial carcinomas, metastases or even lethal outcome may occur in rare cases.

Abstract
We report the case of a 43-year-old woman, who was admitted for intense pelvic pains. Biological investigations showed an increase of β-HCG level. The abdomino-pelvic computed tomography revealed a voluminous mass infiltrating the bladder. A transurethral resection was performed. The histopathological examination evidenced an invasion of the bladder by a massive carcinomatous proliferation composed of clear epithelial cells with in some places syncytiotrophoblastic cells and rarely cytotrophoblastic cells. Immunohistochemical analyses revealed a staining of GATA-3 by the two components, an expression of p63 by the clear cell urothelial component and the immunoreactivity of β-HCG by the trophoblastic component. Ki-67 labeling index was very high. The diagnosis of mixt urothelial carcinoma with clear cells and trophoblastic differentiation was proposed. This is a rare difficult histopathological diagnosis which should be known by pathologists. It is correlated to a poor clinical outcome with a high tendency to lymph node or visceral metastases.

Abstract
INTRODUCTION The ISUP (International Society of Urological Pathology) Consensus Conferences between 2012 and 2015 made recommendations regarding the classification, staging, prognostic factors of adult tumors from kidney, prostate, bladder and testis. The main points of these recommendations are highlighted in this article. MATERIALS AND METHODS This article is based on a systematic literature search by using different keywords "cancer, kidney, prostate, bladder, testis, pathology, classification" from Pubmed database. Only publications between 2012 and 2015 were retained. RESULTS The different Consensus conferences since 2012 in uropathology have provided international guidelines for the classification, grading and staging of tumors in kidney, bladder, prostate and testis. We identified in this article the main points of these new guidelines that are about to be published in the new 2016 WHO classification of urogenital tract tumors in adult. CONCLUSION New pathological guidelines in urogenital tumors have to be taken into account for a better diagnosis and therapy.

Abstract
PURPOSE Neuroendocrine carcinoma of the bladder is a rare tumour representing 0.5 to 1% of bladder tumours. It is a specific histological entity characterized by rapid metastatic dissemination and poor prognosis. The aim of this study was to describe the epidemiological, clinical, therapeutic modalities and the evolutive aspects of patients receiving a treatment for bladder neuroendocrine carcinoma. PATIENTS AND METHODS Between January 2004 and January 2014, seven patients received a treatment for a neuroendocrine carcinoma of the bladder, at the department of oncology, Habib-Bourguiba Hospital, in Sfax, Tunisia. RESULTS The median age was 58 years. All patients were male. Neuroendocrine carcinoma was pure in four cases and associated with urothelial carcinoma in the other three cases. Two patients were diagnosed at a metastatic stage. A cystectomy was performed in two cases. One patient received a chemotherapy and radiotherapy. The other four patients received chemotherapy alone. A single case of complete remission was observed. Median survival was 15 months (5-30 months). One patient is still alive 30 months after diagnosis. CONCLUSION The management of neuroendocrine carcinoma of the bladder is not standardized and requires a multidisciplinary consultation.

Abstract
OBJECTIVE To review the differences between the BCG strains used for the treatment of non-muscle invasive bladder cancer (NMIBC) at the molecular level, regarding cytotoxicity, immunogenicity, clinical efficiency, and safety. MATERIAL AND METHOD A systematic review of the literature search was performed from the database MedLine, focused on the following keywords: BCG; bladder; strain; genome; cytotoxicity; immune response; efficiency; safety. RESULTS Genetic differences between BCG strains have been identified and correlated to their time to differentiation from their initial cultures start, assuming a lower resistance to the host immune defenses of Tice and Danish strains compared to the Connaught strain. Preclinical comparative data showed superior cytotoxic effect and immunogenicity of the Connaught strain compared to Tice and Danish strains. The phase III trials have shown superior efficiency of BCG Connaught compared to BCG Tice and BCG Danish compared to BCG Tice regarding recurrence-free survival. CONCLUSIONS Among BCG strains used in France in NMIBC treatment, preclinical and clinical efficiency of Connaught strain was higher than that of the Tice strain. The limits of the currently available studies lie primarily in the lack of use of maintenance therapy.

Abstract
GOAL The aim was to review the literature on genito-urinary dysfunction in multiple sclerosis (MS). MATERIAL A literature review through the PubMed library until August, 31 2013 was carried out using the following keywords: multiple sclerosis and neurogenic bladder, neuropathic bladder, bladder, management, follow-up, urological complications, urological treatment, sexual dysfunction, female sexual function, male sexual function, erectile dysfunction, anorectal, faecal, constipation, bowel, pregnancy, parturition, delivery, breast-feeding. RESULTS Genito-urinary dysfunction is frequent in MS (35-90%) and may happen soon in the disease. Urinary symptoms (10-90%) are manifold resulting in a quality of life alteration and the onset of complications in 30% of the cases requiring a long-term follow-up. Sexual dysfunctions (35-87%) are also manifold affecting all the sexuality domains in men and women. Except the phosphodiesterase V inhibitors, few treatments have been assessed in this population. Pregnancy is nowadays considered as beneficial resulting in a disease slow-down and the lack of disease worsening despite an increase in disease relapse during the post-partum first quarter. It seems to be better to consider getting pregnant after at least one year without any relapse and to emphasize an exclusive breast-feeding. CONCLUSION Urinary and sexual dysfunctions are frequent in MS. A transdisciplinary approach including the neurologist and pelviperineology specialists facilitates a disability adapted early management.
