Treatment of lower urinary tract symptoms suggestive of benign prostatic hyperplasia in relation to the patient's risk profile for progression

BJU INTERNATIONAL, Issue 2005
John Trachtenberg
SUMMARY Lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH) is a slowly progressing disease, with some patients progressing more rapidly than others. In 80% of patients who progress this is caused by the worsening of symptoms. The physician can predict the risk of progression from the patient's clinical profile; increased symptom severity, a poor maximum urinary flow rate (Qmax), and a high postvoid residual urine volume (PVR), are major risk factors for overall clinical progression of LUTS/BPH. A large baseline prostate volume and a high serum prostate-specific antigen (PSA) level are the predominant risk factors for developing acute urinary retention. After predicting risk, the most appropriate treatment should be established by balancing the benefits of treatment against the possible risks and bother resulting from adverse events. From the Medical Therapy Of Prostatic Symptoms study it can be concluded that monotherapy with an ,1 -adrenoceptor (AR) antagonist is an appropriate treatment for many patients with LUTS/BPH. However, for those at high risk of progression (those with a large prostate volume and high PSA level), it appears more appropriate to add a 5,-reductase inhibitor to the ,1 -AR antagonist to obtain maximum relief of symptoms, and ideally to halt the progression of the disease. This was confirmed by the RAND Appropriateness Method study, in which 12 urologists determined the most appropriate treatment for patients with LUTS/BPH based on their clinical profile, combination of clinical variables and/or risk factors. This study also indicates that patients at very high risk of progression, with severe obstruction (poor Qmax and high PVR), are potential candidates for immediate surgery. [source]

Abstract Aims To examine associations of data from frequency-volume charts with maximum free flow rate, residual volume, and voiding cystometric estimated urethral obstruction grade and detrusor contractility in men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (BPH). Methods The 160 men included in the study met the criteria of the International Scientific Committee on BPH, i.e., they voided more than 150 mL during uroflowmetry, their residual volume and prostate size were estimated, and they completed frequency-volume charts correctly. From the frequency-volume charts, voiding habits and fluid intake were evaluated. Pressure-flow studies were performed as well. Results Increasing residual volume was related to a decrease of maximum voided volume and to a decrease of maximum free flow rate. Cystometric capacity was little affected by residual volume. Low contractility did not result in high residual volume. A marked decrease in voided volumes with increasing obstruction grade was observed, due to a decrease of cystometric capacity and an increase of residual volume. Detrusor contractility was little associated with voided volumes. A higher voiding frequency was related to a higher fluid intake. However, increased standardized frequency (number of voidings per 1,000 mL) was associated with a substantial reduction of fluid intake. Conclusions Infravesical obstruction is the most important factor influencing voided volumes, cystometric capacity, and residual urine volume. Frequency of voiding was not influenced significantly because patients with small voided volumes minimized their fluid intake. Neurourol. Urodynam. 21:450,456, 2002. © Wiley-Liss, Inc. [source]


Data from frequency-volume charts versus filling cystometric estimated capacities and prevalence of instability in men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia

NEUROUROLOGY AND URODYNAMICS, Issue 2 2002

Abstract The aim was to examine associations of filling cystometric estimated compliance, capacities, and prevalence of bladder instability with data from frequency-volume charts in a well-defined group of men with lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH). Men with LUTS suggestive of BPH were included if they met the criteria of the International Consensus Committee on BPH, i.e., they voided more than 150 mL during uroflowmetry, their residual volume and prostate size were estimated, and they completed frequency-volume charts correctly. From the frequency-volume charts, voiding habits, and fluid intake in the daytime and at night were evaluated. Filling cystometric studies were performed in these men as well. Decreased compliance was an exceptional finding. Cystometric capacity and especially effective capacity (cystometric capacity minus residual volume) corresponded significantly with the maximum voided volume on the frequency-volume charts. Effective capacity was almost twice as high as the average voided volume. Minimum voided volume on frequency-volume charts was not related to filling cystometric data. The presence of instability in the supine or sitting position or in both positions was not significantly associated with smaller voided volumes, higher nocturia, or diuria. Filling cystometric capacities were strongly associated with maximal and mean voided volumes derived from frequency-volume charts. The presence of detrusor instability during filling cystometry did not significantly affect voided volumes, diuria, or nocturia. Neurourol. Urodynam. 21:106,111, 2002. © 2002 Wiley-Liss, Inc.

Interactions between prostate volume, filling cystometric estimated parameters, and data from pressure-flow studies in 565 men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia

Abstract The aim of this study was to establish the characteristics and to investigate the interactions between prostate volume, degree of obstruction, bladder contractility, the prevalence of residual volume, bladder compliance, bladder capacities, and the prevalence of instability in a large, well-defined group of men with lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH). The 565 consecutive men included in this study met the criteria of the International Consensus Committee on BPH and voided more than 150 mL during uroflowmetry. Their residual urine volume and prostate size were estimated, and filling cystometry and pressure-flow studies were performed. Fifty-three percent of the men appeared to have obstruction. We found a positive correlation between prostate volume and Schäfer's obstruction grade, except that mean prostate volume decreased at Schäfer's grades 5 and 6. Significant negative correlations existed between Schäfer's grade and cystometric bladder capacity and effective capacity. Bladder outlet obstruction results in incomplete emptying. Of all men, 26% had a significant residual volume (,>,20% of cystometric capacity). Thirty-nine percent did not have residual volume. Of the 565 men, 46% had an unstable bladder. In particular, patients with an unstable bladder in the sitting and lying positions have a significantly higher Schäfer's grade and contractility grade and a significantly lower cystometric and effective bladder capacity compared with patients without instability. Patients with a residual volume or instability were significantly older. We conclude that in men with LUTS suggestive of BPH, abnormalities of bladder and bladder outlet function vary greatly and have complex mutual interactions. Neurourol.

The role of anticholinergics in men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia: a systematic review and meta-analysis

Authors from the UK present a systematic review of publications on the safety and efficacy of anticholinergics in men with LUTS; they found them to be safe, but suggested that further studies are required to establish precisely their efficacy. Authors from the USA studied the correlation between risk factors for vascular disease and the AUA symptom score; there was a possible association between vascular disease and the development and severity of LUTS in men. OBJECTIVE To assess the safety and efficacy of anticholinergics in men with lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH) by a systematic review of published reports and a meta-analysis of the reported outcomes. METHODS We searched Medline, Embase and Cochrane databases (1966,2006), and hand-searched relevant reference lists and conference proceedings, for studies on the use of anticholinergics in men with BPH or bladder outlet obstruction. Eligible studies were assessed for quality and foreign language studies were translated. We collected data on all reported outcomes, conducted meta- analyses on the maximum urinary flow rate (Qmax), postvoid residual urine volume (PVR) and volume at first contraction, and calculated the acute urinary retention (AUR) rate. We used sensitivity analysis to confirm the findings. RESULTS We identified five randomized controlled trials (RCTs) and 15 observational studies. Four RCTs incorporating 633 patients were included in the meta-analyses. Anticholinergics did not significantly alter Qmax (0.1 mL/s, 95% confidence interval, CI, 0.6,0.7). The PVR was increased by 11.6 mL (95% CI 4.5,18.6) although there was no significant difference between AUR rates. The total International Prostate Symptom Scores (IPSS) were not significantly different, but there were improvements for IPSS storage subscores in one RCT. The AUR rate was 0.3% at the 12-week follow-up in 365 men in the RCTs and observational studies. CONCLUSION Anticholinergic use in men with LUTS suggestive of BPH appears to be safe. Further studies are required to establish efficacy with a suitable precision. [source]


LUTS/BPH in clinical practice: the importance of nocturia and quality of sleep

BJU INTERNATIONAL, Issue 2006
EMMANUEL CHARTIER-KASTLER
Various studies indicate that nocturia is one of the most bothersome of lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH). Nocturia has a negative impact on quality of sleep (QoS), which might lead to daytime fatigue, reduced performance the next day and might ultimately affect the patient's overall quality of life (QoL). However, the evaluation of a patient with LUTS/BPH and assessment of benefits of LUTS/BPH treatment are mainly focused on voiding symptoms or flow rate, and the impact of nocturia on the patient's QoL is often neglected. At the Sixth International Consultation on Prostate Cancer and Prostate Diseases in 2005, a discussion forum about nocturia and its impact on QoS and QoL was organized, followed by a meeting of an expert consensus panel. Both recognized the importance of assessing nocturia and its impact on QoS and QoL in the initial evaluation of patients with LUTS/BPH, and in assessing the benefits of (new) LUTS/BPH treatments. However, currently used instruments that measure the severity of nocturia and its impact on QoS and QoL were not specifically designed for this purpose and lack sensitivity. At the expert consensus meeting, the expert panel stated that new instruments are required that can fully monitor the impact of nocturia on QoS and QoL. Potential new instruments that address these requirements are nocturia-specific questionnaires such as the Nocturia QoL questionnaire. Furthermore, the expert panel acknowledged the assessment of ,hours of undisturbed sleep' (HUS) as a potential new method to evaluate the impact of nocturia on QoS and QoL. HUS refers to the time from falling asleep to the first awakening to void. Sleep assessment tools such as sleep diaries and actigraphy are potential instruments to measure HUS. [source]
