          Abstract

          Abstract Introduction: Despite the technical and scientific progress that improved therapeutic resources available in Oncology, adverse effects of treatment can be prominent, impacting the quality of life (QoL). Objective: This research aims to determine the prevalence of post-radiotherapy pelvic symptoms in prostate cancer (PC) and its impact on QoL. Methods: We assessed three groups of patients at different stages during radiotherapy (RT): Pre-RT, evaluated before of RT; Post-RT#1, evaluated between six months and one year post-RT; Post-RT#2, evaluated between two and a half and four years post-RT. The presence of urinary incontinence (UI), its characteristics and impact on daily living activities (DLA) were evaluated by ICIQ-SF questionnaire. WHOQOL-BREF questionnaire was used to assess QoL. Student t test was used, considering significant p < 0.05. Results: Thirty-three men were assessed (pre-RT, n = 12; Post-RT#1, n = 10; Post-RT#2, n = 11). The prevalence of lower urinary tract symptoms (LUTS) was highest in Post-RT#1 group. Post-RT#2 group had the highest prevalence of post-RT UI. In QoL, Pre-RT and Post-RT#2 groups experiencing the greatest impact on physical, environmental and overall QoL. Conclusion: Acute effect of RT is characterized by a high prevalence of LUTS. Post-RT#2 group experienced the most adverse effects on DLA due to a higher prevalence of post-RT UI.

          Resumo Introdução: Apesar do progresso técnico e científico que melhorou recursos terapêuticos disponíveis na Oncologia, efeitos adversos do tratamento podem ser proeminentes, impactando a qualidade de vida (QoL). Objetivo: Esta pesquisa tem como objetivo determinar a prevalência de sintomas pélvicos pós-radioterapia no câncer de próstata (CaP) e seu impacto na QoL. Métodos: Avaliou-se três grupos de pacientes com CaP em diferentes estágios da radioterapia (RT): (1) Pré-RT, avaliados antes da RT; (2) Pós-RT #1, avaliados entre seis meses e um ano pós-RT; (3) Pós-RT #2, avaliados entre dois anos e meio e quatro anos pós-RT. A presença de incontinência urinária (IU), suas características e o impacto sobre as atividades da vida diária (AVD) foram avaliados através do questionário ICIQ-SF. O questionário WHOQOL-BREF foi utilizado para avaliar a QoL. O teste t de Student foi utilizado para análise estatística, considerando significativo p < 0,05. Resultados: Trinta e três homens foram avaliados (pré-RT, n = 12; Pós-RT #1, n = 10; Pós-RT #2, n = 11). A prevalência de sintomas do trato urinário inferior (STUI) foi maior no grupo Pós-RT #1. O grupo Pós-RT #2 teve a maior prevalência de IU pós RT. Na avaliação da QoL, os grupos Pré-RT e Pós-RT #2 apresentaram maior impacto negativo sobre os índices relacionados aos quesitos físico, ambiental e global. Conclusão: O efeito agudo da RT foi caracterizado por uma elevada prevalência de STUI. O grupo Pós-RT #2 experimentaram maior impacto negativo as AVD, devido a uma maior prevalência de IU pós RT.

          Prevalence of urinary incontinence in men, women, and children--current evidence: findings of the Fourth International Consultation on Incontinence.

          To summarize existing evidence relating to the prevalence and risk factors of urinary incontinence in order to provide a concise reference source for clinicians, health researchers, and service planners. For the Fourth International Consultation on Incontinence (4th ICI) world experts identified, collated, and reviewed the best available evidence. Estimates of prevalence from different studies are presented as ranges. Most studies report some degree of urinary incontinence (UI) in 25-45% of women; 7-37% of women aged 20-39 report some UI; "daily UI" is reported by 9% to 39% of women over 60. Pregnancy, childbirth, diabetes and increased body mass index are associated with an increased risk of UI. Prevalence of UI in men approximately half that in women: UI is seen in 11-34% of older men, with 2-11% reporting daily UI. Surgery for prostate disease is associated with an increased risk. Some 10% of children aged seven, 3% of 11-12 years olds and 1% of 16-17 year olds are not dry at night. UI is clearly common, but accurate prevalence data have proven difficult to establish because of heterogeneity between studies in terms of methodologies, definitions of UI and populations considered. Future research should use standardized, validated and more readily comparable methods. Copyright 2010 Elsevier Inc. All rights reserved.

            Effectiveness of early pelvic floor rehabilitation treatment for post-prostatectomy incontinence.

            Urinary incontinence after radical prostatectomy is a significant clinical problem. In this prospective study we investigate the effectiveness of early pelvic floor muscle training (PFMT) on a large population, that had undergone radical retropubic prostatectomy (RRP) at our department. 300 consecutive patients who had undergone RRP for clinically confined prostate cancer were randomized in two groups after catheter removal. One group of 150 patients took part in a structured PFMT program. This began before discharge and consisted of Kegel exercises. The remaining 150 patients constituted the control group, they were not formally instructed in PFMT. Incontinence was assessed objectively using the 1 hour and 24 hour pad test, as well as with the ICS-Male questionnaire. All patients who were incontinent after 6 months underwent urodynamic evaluation. In the treated group, 19% (29 patients) achieved continence after 1 month, and 94.6% (146 patients) after 6 months. In the control group 8% (12 patients) achieved continence after 1 month, and 65% (97 patients) after 6 months (p 0.05), although a significant correlation was revealed within the treated group (p<0.01). Overall, 93.3% of the total population achieved continence after one year. After RRP an early supportive rehabilitation program like PFMT significantly reduces continence recovery time.

              The pathophysiology of post-radical prostatectomy incontinence: a clinical and video urodynamic study.

              We examine various mechanisms of post-radical prostatectomy incontinence. A total of 83 consecutive men (mean age 68 +/- 6.6 years) referred for evaluation of persistent post-radical prostatectomy incontinence were enrolled in the study. All patients underwent clinical and urodynamic evaluation. Final diagnosis was based on clinical judgment considering patient history, pad test, voiding diary, free (unintubated) uroflow measurements, video urodynamics and linear passive urethral resistance relation curves. We compared free uroflow and pressure flow obtained with a 7Fr urethral catheter in place, and empirically defined low urethral compliance as at least 10 ml. per second difference between these measurements. Sphincteric incontinence was the most common urodynamic finding, occurring in 73 patients (88%). Detrusor instability was identified in 28 patients (33.7%) and in 6 (7.2%) was the main cause of incontinence. In 2 other patients bladder outlet obstruction (1.2%) or impaired detrusor contractility (1.2%) was the only urodynamic finding. Impaired detrusor contractility was diagnosed by linear passive urethral resistance relation in 82% of cases but considered to be clinically relevant in only a third. In 25 cases (30.1%) low urethral compliance was noted, which we consider nearly synonymous with urethral scarring. Sphincteric incontinence is the most common urodynamic finding in patients with post-radical prostatectomy incontinence, although other findings may coexist. The most accurate diagnosis is attained when all objective measures are put in perspective with the clinical setting.
