Overactive bladder is a symptom complex consisting of bothersome storage urinary symptoms that is highly prevalent among both sexes and has a significant impact on quality of life. Various antimuscarinic agents and the beta-3 agonists mirabegron and vibegron are currently available for the treatment of OAB. Each drug has specific pharmacologic properties, dosing schedule and tolerability profile, making it essential to individualize the medical treatment for the patient's characteristics and expectations. In this manuscript, we review the most important factors involved in the contemporary pharmacological treatment of OAB.

Objective: To cross-culturally adapt and check for the reliability and validity of the neurogenic bladder symptom score questionnaire to Brazilian Portuguese, in patients with spinal cord injury and multiple sclerosis. Materials and Methods: The questionnaire was culturally adapted according to international guidelines. The Brazilian version was applied in patients diagnosed with neurogenic bladder due to spinal cord injury or multiple sclerosis, twice in a range of 7 to 14 days. Psychometric properties were tested such as content validity, construct validity, internal consistency, and test-retest reliability. Results: Sixty-eight patients participated in the study. Good internal consistency of the Portuguese version was observed, with Cronbach α of 0.81. The test-retest reliability was also high, with an Intraclass Correlation Coefficient of 0.86 [0.76 - 0.92] (p

PURPOSE: To report our experience with the use of the botulinum toxin-A (BoNT/A) formulations Botox® and Prosigne® in the treatment of neurogenic detrusor overactivity (NDO). MATERIALS AND METHODS: At a single institution, 45 consecutive patients with refractory urinary incontinence due to NDO received a single intradetrusor (excluding the trigone) treatment with botulinum toxin type A 200 or 300 units. Botox was used for the first 22 patients, and Prosigne for the subsequent 23 patients. Evaluations at baseline and week 12 included assessment of continence and urodynamics. Safety evaluations included monitoring of vital signs, hematuria during the procedure, hospital stay, and spontaneous adverse event reports. RESULTS: A total of 42 patients were evaluated (74% male; mean age, 34.8 years). Significant improvements from baseline in maximum cystometric capacity (MCC), maximum detrusor pressure during bladder contraction, and compliance were observed in both groups (P < 0.05). Improvement in MCC was significantly greater with Botox versus Prosigne (+103.3% vs. +42.2%; P = 0.019). Continence was achieved by week 12 in 16 Botox recipients (76.2%) and 10 Prosigne recipients (47.6%; P = 0.057). No severe adverse events were observed. Mild adverse events included 2 cases of transient hematuria on the first postoperative day (no specific treatment required), and 3 cases of afebrile urinary tract infection. CONCLUSIONS: Botox and Prosigne produce distinct effects in patients with NDO, with a greater increase in MCC with Botox. Further evaluation will be required to assess differences between these formulations.

Lower urinary tract dysfunction is a major cause of morbidity and decreased quality of life in elderly men and women. With the progressive aging of the population, it is important to understand common micturitional disorders that may occur in this population. Most urinary problems in the elderly are multifactorial in origin, demanding a comprehensive assessment of the lower urinary tract organs, functional impairments, and concurrent medical diseases. Urodynamics is a highly valuable tool in the investigation of elderly patients with lower urinary tract symptoms. Urodynamic tests are not always necessary, being indicated after excluding potentially reversible conditions outside the urinary tract that may be causing or contributing to the symptoms. Although urodynamic tests may reveal common diagnoses such as bladder outlet obstruction and stress urinary incontinence in the elderly population, findings such as detrusor overactivity and impaired detrusor contractility are common and have important prognostic and therapeutic implications. The purpose of this article is to describe common urologic problems in the elderly and review the indications for and clinical aspects of urodynamic studies in these conditions. Disfunções do trato urinário inferior são uma causa importante de morbidade e diminuição da qualidade de vida em homens e mulheres idosos. Com o envelhecimento progressivo da população, é importante compreender os distúrbios miccionais mais comuns nesta população. A maioria dos problemas miccionais em homens idosos tem origem multifatorial, requerendo uma avaliação ampla dos órgãos do trato urinário inferior, da capacidade funcional e neurológica dos pacientes e dos problemas clínicos coexistentes. A avaliação urodinâmica é uma ferramenta importante na investigação de pacientes idosos com sintomas do trato urinário inferior. Ela não é necessária em todos os casos e só deve ser indicada após a exclusão de problemas não urológicos e potencialmente reversíveis que poderiam causar ou contribuir para os sintomas miccionais. Embora os exames urodinâmicos possam revelar diagnósticos comuns como obstrução vesical ou incontinência urinária de esforço, na população idosa é freqüente a ocorrência de achados como hiperatividade detrusora e falência da contratilidade vesical, com implicações prognósticas e terapêuticas importantes. O objetivo deste artigo é descrever os problemas urológicos mais comuns nos idosos e discutir as indicações e características dos exames urodinâmicos nestas condições.
