Neurogenic bladder: concepts and treatment recommendations

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.

Artificial sphincter "BR - SL - AS 904" in the treatment of urinary incontinence after radical prostatectomy: efficacy, practicality and safety in a prospective and multicenter study

ABSTRACT Purpose: The objective of the present study is to test the efficiency and practicality of a new artificial sphincter "BR - SL - AS - 904" in the control of urinary incontinence in post - PR patients and to evaluate their complications. Patients and Methods: Fifteen patients with incontinence after one year of radical prostatectomy were included prospectively. All patients underwent artificial urethral sphincter (AUS) implant "BR - SL - AS - 904" according to established technique. Independent variables such as free urinary flow, PAD weight test, ICIQ - SF score and urinary symptoms through the IPSS score were compared in different follow-up moments. Results: Patients submitted to AUS implantation did not present trans - operative or post - operative complications related to the surgical act such as: infection, hematoma, erosion or urinary retention. Device was inert to the body during the follow-up, showing an excellent adaptation of the patients, besides the easy handling. The mean age was 68.20 years 40% of the patients had systemic arterial hypertension, 6.7% diabetes mellitus, 6.7% were hypertensive and diabetic, 13.4% were hypertensive, had diabetes and hypercholesterolemia and 26.7% patients had no comorbidities. It was evidenced that the urinary flow peak during the follow-up remained stable. Decreased averages and median PAD weight test were 135.19 to 75.72 and 106.00 to 23.50, respectively. The IPSS score decreased and the quality of life increased (12.33 to 3.40 and 2.50 to 3.20 respectively). The ICQF - SF questionnaire score also showed a decrease, ranging from 16, 71 to 7.33. Conclusion: The artificial sphincter implant "BR - SL - AS 904" was reproducible, safe and effective in the control of urinary incontinence in post - PR patients.

PSA kinetics before 40 years of age

ABSTRACT Purpose: The baseline PSA has been proposed as a possible marker for prostate cancer. The PSA determination before 40 years seems interesting because it not suffers yet the drawbacks related to more advanced ages. Considering the scarcity of data on this topic, an analysis of PSA kinetics in this period seems interesting. Materials and Methods: A retrospective assay in a database of a private diagnostic center was performed from 2003 to 2016. All subjects with a PSA before 40 years were included. Results: 92995 patients performed PSA between the ages of 21 - 39. The mean value ranged from 0.66 ng / mL (at age 22) to 0.76 ng / mL (at age 39) and the overall mean was 0.73 ng / mL. As for outliers, 3783 individuals presented a baseline PSA > 1.6 ng / mL (p95). A linear regression model showed that each year there is a PSA increase of 0.0055 ng / mL (β = 0.0055; r2 = 0.0020; p < 0.001). A plateau in PSA between 23 and 32 years was found and there were only minimal variations among the ages regardless of the evaluated percentile. Conclusion: It was demonstrated that PSA kinetics before 40 years is a very slow and progressive phenomenon regardless of the assessed percentile. Considering our results, it could be suggested that any PSA performed in this period could represent the baseline value without significant distortions.

Can hydrophilic coated catheters be beneficial for the public healthcare system in Brazil? - A cost-effectiveness analysis in patients with spinal cord injuries

ABSTRACT Introduction Detrusor sphincter dyssynergia affects 70% to 80% of all spinal cord injury patients, resulting in increased risk of urinary tract infections (UTIs) and potential exposure to antimicrobial resistance. In Brazil, local guidelines recommend intermittent catheterization as the best method for bladder emptying, and two catheter types are available: the conventional uncoated PVC and the hydrophilic coated catheters. Objective To evaluate the cost-effectiveness of two types of catheters for intermittent catheterization from the perspective of the Brazilian public healthcare system. Materials and Methods A Markov model was used to evaluate cost-effectiveness in those with spinal cord injuries. A primary analysis was conducted on all possible adverse events, and a secondary analysis was performed with urinary tract infections as the only relevant parameter. The results were presented as cost per life years gained (LYG), per quality-adjusted life years (QALY) and per number of urinary tract infections (UTIs) avoided. Results The base scenario of all adverse events shows a cost-effective result of hydrophilic coated catheters compared to uncoated PVC catheters at 57,432 BRL (Brazilian Reais) per LYG and 122,330 BRL per QALY. The secondary scenario showed that the use of hydrophilic coated catheters reduces the total number of UTIs, indicating that an additional cost of hydrophilic coated catheters of 31,240 BRL over a lifetime will reduce lifetime UTIs by 6%. Conclusions Despite the higher unit value, the use of hydrophilic coated catheters is a cost-effective treatment from the perspective of the Brazilian public healthcare system.

Overactive bladder - 18 years - Part II

ABSTRACT 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.

Overactive bladder - 18 years - Part I

ABSTRACT Abstract: 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.

Metodologia da análise seminal para pacientes azoospérmicos no laboratório fleury / Methodology of seminal analysis for azoospermicos patients in the laboratório fleury

A azoospermia é definida como a ausência de espermatozoide no líquido seminal ejaculado pelo homem depois de aplicada a técnica de centrifugação em pelo menos duas amostras. Dada a importância de um diagnóstico correto da análise seminal para os casais, toda amostra que não apresentar espermatozoides no exame a fresco deve seguir em avaliação laboratorial. Com isso, o presente estudo tem como objetivo analisar os resultados de centrifugação de uma alíquota do sêmen ejaculado ou de todo o volume ejaculado de pacientes com diagnóstico de azoospermia para determinar qual o melhor método a ser empregado na análise seminal para esse grupo de pacientes.

The azoospermia is defined as the absence of sperm in the ejaculate by the seminal fluid man after centrifugation technique conducted in at least two samples. Given the importance of a correct diagnosis of the seminal analysis for couples, all sample no sperm present in fresh examination should follow in laboratory tests. Thus the present study aims to analyze the results of a spin rate of ejaculate or all of the ejaculate volume of patients with azoospermia to determine the best method to be used in semen analysis for this group of patients.

Estudo do comportamento vesical durante cistometriais com soluçöes de diferentes osmolaridades / Study of bladder behavior during cystometries with different osmolality solutions

Introdução e objetivos: Variações nas características bioquímicas e biofísicas da urina poderiam estar associadas a diferentes respostas e sensações vesicais. O objetivo deste estudo é verificar se o uso de soluções hiper e hipo-osmolares durante o exame urodinâmico promove diferentes respostas do comportamento vesical. Método: Trinta e três pacientes, vinte e quatro homens e nove mulher es, com idade média de 46,4 anos (8 - 87 anos) e indicação de avaliação urodinâmica, participaram deste estudo. Todos foram submetidos a dois exames urodinâmicos consecutivos. Em cada exame foi realizado o enchimento vesical, com uma solução hiperosmolar (1OOO mOsm/litro), ou com uma solução hipo-osmolar (1OO mOsm/litro) de Cloreto de Sódio. Um técnico manipulou as soluções sem que suas constituições fossem reveladas. A seqüência em que as soluções foram infundidas foi determinada por sorteio, em caráter duplo cego. Os pacientes foram agrupados por idade, sexo, presença ou não de neuropatia e hiperatividade detrusora. Comparamos os resultados obtidos com a infusão da solução hiperosmolar e hipo-osmolar, independente da seqüência em que foram administradas. Valores pressóricos e volumétricos referentes à sensação inicial e, habitual de enchimento vesical, sensação de plenitude, presença de contrações vesicais involuntárias, complacência e dados do estudo miccional, foram registrados para cada grupo. Os valores obtidos foram submetidos a análise estatística pelo método multivariado de análise de perfil de médias, assumindo-se p
