What's known on the subject? and What does the study add? Bilateral testicular germ cell tumours (BTGCTs) are rare neoplasms. Most previously published studies consist of case reports or small retrospective case series. Little is known about their epidemiological and clinicopathological characteristics. BTGCT corresponded to 1.82% of testicular tumours. Metachronous disease was about twice as frequent as synchronous disease. The primary tumour histology, chemotherapy use and the interval between metachronous tumours influenced the histology of the second tumour. Overall, synchronous tumours were associated with more advanced disease and presented less favourable survival rates than metachronous tumours. Testicular cancer is the most common tumour in young men. It is known that a second primary contralateral testis tumour may occur in up to 5% of men with a proior tumour. About 35% of these men present with synchronous tumours, and 65% present with metachronous tumours. However there is little data about bilateral testicular germ cell tumours (BTGCT) in the literature and the most published articles are case reports on a small series of men, which makes it difficult to draw conclusions about therapeutic strategies for the treatment of BTGCTs. In fact, current guidelines for the treatment of testicular cancer contain little information related to bilateral disease. Therefore, the aim of our study is to provide a broad overview of BTGCT and to update data focusing on incidence, pathological features, and clinical outcomes of men with BTGCTs. Thus, an extensive review containing 94 studies and more than 50,000 patients was conducted.

Introduction: Bladder and urinary sphincter malfunctioning that results from some change in the central and/or peripheral nervous system is defined as neurogenic bladder. The urinary tract symptoms that can be related to its filling, emptying, or both have a significant impact on the quality of life of individuals. The present review was based on the document prepared for the public health system in Brazil as a treatment guidelines proposal. Material and Methods: Survey questions were structured as per PICO (Population, Intervention, Control, and Outcome). Search strategies were defined and performed in the MEDLINE/Pubmed, Embase, Epistemonikos and Google Scholar databases. The selection of articles followed the evidence hierarchy concept; evidence body was identified, and the quantitative study data were extracted. The quality of evidence and grade of recommendation were qualitatively assessed according to GRADE (Grading of Recommendations, Assessment, Development and Evaluations). Results: A total of 2.707 articles were identified, with 49 of them being selected to compose the basis for this review. Neurogenic bladder treatments were classified according to their focus on filling or emptying symptoms and sub-classified in pharmacological and surgical treatments. Conclusion: Treatment guidelines are important tools for the public health system to promote the best practice when treating neurogenic bladder patients.

Purpose: To evaluate preoperative rectal electrical stimulation in the recovery of urinary continence in patients who undergo radical retropubic prostatectomy. Materials and Methods: Patients were divided into 3 randomized groups: control, pelvic exercises, and electrical stimulation. A 1 hour pad-test, the ICIQ-SF, and the SF-36 were performed 1, 3, and 6 months after the surgical procedure. Results: Of the 58 patients who were initially included in the study, 9 were excluded due to radiotherapy after surgical intervention, an indwelling urethral catheter for more than 30 days, high surgical risk, loss of follow-up, or incomplete participation in the study routines and spontaneous interruption. Forty-nine patients concluded the study (15 in the control group, 17 in the exercise group, and 17 in the electrical stimulation group). We did not observe any significant difference in the pad test (p > 0.05), the 8 domains of the SF-36, or ICIQ-SF score compared with control groups (control, exercise, and electrical stimulation). Conclusion: Preoperative rectal electrical stimulation has no impact on continence status in patients who undergo radical retropubic prostatectomy. There is no difference in the three above mentioned groups with regard to urinary leakage and quality of life.

GATA3 was positive in all extramammary Paget disease cases tested (13 cases), and it has no value for differentiating between primary and secondary vulvar Paget disease from the urological tract. HER2 amplification might confer an aggressive and invasive pattern in primary vulvar Paget disease, as both amplified cases showed an invasive pattern.

Overactive bladder syndrome is one of the lower urinary tract dysfunctions with the highest number of scientific publications over the past two decades. This shows the growing interest in better understanding this syndrome, which gathers symptoms of urinary urgency and increased daytime and nighttime voiding frequency, with or without urinary incontinence and results in a negative impact on the quality of life of approximately one out of six individuals – including both genders and almost all age groups. The possibility of establishing the diagnosis just from clinical data made patients' access to specialized care easier. Physiotherapy resources have been incorporated into the urological daily practice. A number of more selective antimuscarinic drugs with consequent lower adverse event rates were released. Recently, a new class of oral drugs, beta-adrenergic agonists has become part of the armamentarium for Overactive Bladder. Botulinum toxin injections in the bladder and sacral neuromodulation are routine modalities of treatment for refractory cases. During the 1st Latin-American Consultation on Overactive Bladder, a comprehensive review of the literature related to the evolution of the concept, epidemiology, diagnosis, and management was conducted. This text corresponds to the first part of the review Overactive Bladder 18-years.

Traditionally, the treatment of overactive bladder syndrome has been based on the use of oral medications with the purpose of reestablishing the detrusor stability. The recent better understanding of the urothelial physiology fostered conceptual changes, and the oral anticholinergics – pillars of the overactive bladder pharmacotherapy – started to be not only recognized for their properties of inhibiting the detrusor contractile activity, but also their action on the bladder afference, and therefore, on the reduction of the symptoms that constitute the syndrome. Beta-adrenergic agonists, which were recently added to the list of drugs for the treatment of overactive bladder, still wait for a definitive positioning – as either a second-line therapy or an adjuvant to oral anticholinergics. Conservative treatment failure, whether due to unsatisfactory results or the presence of adverse side effects, define it as refractory overactive bladder. In this context, the intravesical injection of botulinum toxin type A emerged as an effective option for the existing gap between the primary measures and more complex procedures such as bladder augmentation. Sacral neuromodulation, described three decades ago, had its indication reinforced in this overactive bladder era. Likewise, the electric stimulation of the tibial nerve is now a minimally invasive alternative to treat those with refractory overactive bladder. The results of the systematic literature review on the oral pharmacological treatment and the treatment of refractory overactive bladder gave rise to this second part of the review article Overactive Bladder – 18 years, prepared during the 1st Latin-American Consultation on Overactive Bladder.

Study design: Retrospective study. Objective: To determine if spinal cord injuries due to gunshot wounds (GW) are associated with dierent bladder and sphincteric behavior compared to other trauma mechanisms. Setting: Spinal injury center, Brazilian university hospital. Methods: We retrospectively evaluated the records and urodynamic studies of 71 patients with spinal cord injury (SCI) referred to the Brazilian National Spinal Cord Injury Center over the year 2000, and compared the bladder-sphincteric pattern of patients with injuries caused by GW with those caused by other trauma mechanisms. Results: The causes of SCI were (1) gunshot wounds (31 patients: 43.7%); (2) motor vehicle accidents (16 patients: 22.5%); (3) falls (16 patients: 22.5%) and (4) diving (three patients: 4.2%). In ®ve patients (7.1%) the causes were unusual trauma mechanisms like stab wound (one patient) and direct trauma in vigorous sports (two patients) or ®ghts (two patients). The levels of the injuries were cervical in 22 patients (31.0%), thoracic in 39 (54.9%) and lumbar in 10 (14.1%). Detrusor hyperre¯exia with detrusor ± sphincter dyssynergia was present in 65% of the patients overall and in 76% of the thoracic gunshot wounded. Are¯exia occurred in 20% of the patients and in 16% of thoracic injured patients with gunshots. Detrusor hyperre¯exia with detrusor ± sphincter dyssynergia was the pattern encountered in 50% of the individuals suering from SCI because of other mechanisms and are¯exia was present in 35.8%. There was no statistical dierence between GW patients and other mechanisms according to bladder and sphincter functions. Conclusions: There was a substantial overlap of bladder and sphincteric behaviors between patients with dierent levels of spinal injuries, but the trauma mechanism was not important to determine the bladder and sphincteric functions.

Purpose:To analyze the association between obesity and urinary incontinence rate in men submitted to robot-assisted radical prostatectomy (RARP) in a high-volume cancer center. Materials and Methods: We reported 1.077 men who underwent RARP as the primary treatment for localized prostate cancer from 2013 to 2017. Patients were classifi ed as non-obese (normal BMI or overweight) or obese men (BMI ≥30kg/m 2 ). They were grouped according to the age, PSA level, D'Amico risk group, Gleason score, ASA classifi cation, pathological stage, prostate volume, salvage/adjuvant radiotherapy, perioperative complications, and follow-up time. Urinary continence was defi ned as the use of no pads. For the analysis of long-term urinary continence recovery, we conducted a 1:1 propensity-score matching to control confounders. Results: Among the obese patients, mean BMI was 32.8kg/m 2 , ranging 30 -45.7kg/m 2 . Only 2% was morbidly obese. Obese presented more comorbidities and larger prostates. Median follow-up time was 15 months for the obese. Complications classifi ed as Clavien ≥3 were reported in 5.6% of the obese and in 4.4% of the non-obese men (p=0.423). Median time for continence recovery was 4 months in both groups. In this analysis, HR was 0.989 for urinary continence recovery in obese (95%CI=0.789 -1.240; p=0.927). Conclusions: Obese can safely undergo RARP with similar continence outcomes comparing to the non-obese men when performed by surgeons with a standardized operative technique. Future studies should perform a subgroup analysis regarding the association of obesity with other comorbidities, intending to optimize patient counseling.
