“…Most community-based studies showed that age and symptom scores showed a positive correlation (16)(17)(18)(19)(20) as well as an increase in LUTS severity with age. Despite some studies showing a negative correlation between age and symptom indexes (11,21), the majority of the studies including ours showed an increase in symptom scores with age. Patients often complaint about more severe symptoms as their daily-life activities are disrupted and consequently, their quality of life is reduced (22,23).…”

“…Moreover, we also found statistically significant correlations with increased post-void residue with the severity of symptoms in IPSS questionnaire. Likewise, another study in the literature showed a significant relationship between IPSS and post-void residue (11). When IPSS scores and prostate volume and PSA were compared, we detected a significant correlation between those parameters.…”

“…Although most of those symptoms are seen in prostate enlargement, they can also be caused by other conditions such as neurogenic bladder, urethral stricture or urinary tract infections (8)(9). A large number of studies showed a correlation between MLUTS and prostate volume, peak flow speed, residual volume and PSA (10,11). However, there are also a few studies that say otherwise (i.e.…”

Indroduction: Benign prostate hyperplasia (BPH) is the most commonly diagnosed benign adenoma which causes serious clinical symptoms by bladder outlet obstruction. BPH patients suffer from negative changes in their quality of life and restriction of their daily activities due to the disease symptoms. Our main objective in this study is to evaluate the relationship between BPH and LUTS as described by International Prostate Symptoms Score and objective non-invasive parameters related to BPH. Materials and methods: 238 Patients over 40 years with clinical BPH, LUTS and/or prostate volumes greater than 25 ml who presented to urology department were included in the study. All patients included in the study were subjected to a standardized diagnostic panel which included patient history, physical examination, biochemistry panels and urinalysis. Results: Results showed an increase in symptom scores with age. As symptom scores go from mild to severe; Q max values showed a decrease meanwhile prostate volume, PSA and postvoid residue increased. Again, in terms of erectile dysfunction, erectile dysfunction complaints increased with increased IIEF symptom scores. When all these results were evaluated, a positive correlation was seen between uroflowmetry parameters with patient symptoms, PSA and IIEF scores. Conclusion: From our study results, we can conclude that uroflowmetry is a very useful tool in monitoring lower urinary system complaints.KEY WORDS: Prostate volume; Erectile dysfunction; Uroflowmetry; Urinary system complaints. toms (LUTS) (5, 6).

“…Uroflowmetry was assessed in 2580 patients across 16 studies. Thirteen studies used a cutoff value of 10 ml/s to diagnose BOO and reported median sensitivity of 68.3%, specificity of 70.5%, a PPV of 74.3% and NPV of 68% [7,12,13,15,16,18,20,21,26,30,33,34,38,40,41]. However, studies varied considerably in their choice of defining variable and cutoff values.…”

Systematic Review of the Performance of Noninvasive Tests in Diagnosing Bladder Outlet Obstruction in Men with Lower Urinary Tract Symptoms

Keywords:Bladder outlet obstruction (BOO) Men Lower urinary tract symptoms Diagnosis Urodynamics Noninvasive Systematic review Please visit www.eu-acme.org/ europeanurology to read and answer questions on-line. The EU-ACME credits will then be attributed automatically. AbstractContext: Several noninvasive tests have been developed for diagnosing bladder outlet obstruction (BOO) in men to avoid the burden and morbidity associated with invasive urodynamics. The diagnostic accuracy of these tests, however, remains uncertain. Objective: To systematically review available evidence regarding the diagnostic accuracy of noninvasive tests in diagnosing BOO in men with lower urinary tract symptoms (LUTS) using a pressure-flow study as the reference standard. Evidence acquisition: The EMBASE, MEDLINE, Cochrane Database of Systematic Reviews, Cochrane Central, Google Scholar, and WHO International Clinical Trials Registry Platform Search Portal databases were searched up to May 18, 2016. All studies reporting diagnostic accuracy for noninvasive tests for BOO or detrusor underactivity in men with LUTS compared to pressure-flow studies were included. Two reviewers independently screened all articles, searched the reference lists of retrieved articles, and performed the data extraction. The quality of evidence and risk of bias were assessed using the QUADAS-2 tool. Evidence synthesis: The search yielded 2774 potentially relevant reports. After screening titles and abstracts, 53 reports were retrieved for full-text screening, of which 42 (recruiting a total of 4444 patients) were eligible. Overall, the results were predominantly based on findings from nonrandomised experimental studies and, within the limits of such study designs, the quality of evidence was typically moderate across the literature. Differences in noninvasive test threshold values and variations in the urodynamic definition of BOO between studies limited the comparability of the data.

Relación del residuo post-miccional, grado de "trabeculación" vesical y el flujo urinario en pacientes con hiperplasia prostática benigna sintomática.Relationship between post-mictional residue, degree of bladder trabeculation and urinary flow in patients with benign prostatic hyperplasia. Humberto Condori 1 , Raúl Medina 2 , Cesar Loza RESUMENObjetivo: Determinar la relación entre el grado de "trabeculación" vesical, el residuo pos miccional y el grado de obstrucción al flujo de salida urinario en pacientes con hiperplasia benigna de próstata (HBP) sintomática. Material y métodos: Serie de casos analítico y retrospectivo que incluyó 37 pacientes con HBP sintomática atendidos ambulatoriamente en el servicio de Urología del Hospital Nacional Cayetano Heredia en el 2009. El grado de "trabeculación" vesical se determinó por cistoscopia, el residuo vesical post-miccional por ecografía y el grado de obstrucción mediante uroflujometría. Resultados: La edad de los pacientes fue: 68,2 ± 7,9 (50-83) años. Los valores del volumen prostático, porcentaje de residuo post-miccional y el flujo máximo fueron: 46,4 ± 20,6 cc (20-113); 33,4% ± 20,7 (5-80) y 6,7 ± 2,12 7 ml/seg (3-10), respectivamente. No se encontró correlación entre: el porcentaje de residuo post-miccional y el flujo urinario máximo (r s = -0,07; p=0,67) y entre el volumen prostático y el flujo máximo con (r s = 0,05; p= 0,7). Tampoco se encontró concordancia entre el grado de "trabeculación" vesical y el flujo máximo (Kappa= 0,0034; p=0,5) y entre el porcentaje de residuo post-miccional y el grado de "trabeculación" (Kappa= 0,18; p=0,06). Conclusión: No se encontró relación entre el flujo máximo urinario, el porcentaje de residuo post-miccional y el grado de "trabeculación", en pacientes con HBP sintomática.PALABRAS CLAVE: Próstata, cistoscopia, vejiga urinaria. (Fuente: DeCS BIREME) SUMMARYObjective: To determine the relationship between the degree of bladder trabeculation, post mictional residue and degree of urinary outflow obstruction in patients with benign prostatic hyperplasia (BPH). Methods: Retrospective case series of 37 ambulatory patients with symptomatic BPH attended at the Urology Service of Hospital Nacional Cayetano Heredia in 2009. The degree of bladder trabeculation was determined by cystoscopy, post-mictional residue was measured by ultrasound, and the degree of outflow obstruction was measured by uroflowmetry. Results: Mean (SD) age of patients was 68.2 ± 7.9 years. Mean (SD) values for prostatic volume, percentage of postmictional residue and maximum flow were 46.4 ± 20.6 ml; 33.4 ± 20.7% y 6.7 ± 2.1 ml/seg, respectively. No correlation between the percentage of post-mictional residue and maximum urinary flow (rs = -0.07; p = 0.67), and between prostatic volume and maximum urinary flow was found (rs = 0.05; p = 0.7). There were also no correlations INTRODUCCIÓNLa identificación del paciente con diagnóstico de hiperplasia prostática benigna (HBP) y uropatía obstructiva requiere de pruebas diagnósticas y score de síntomas con la finalidad de...
