Home and office uroflowmetry for evaluation of LUTS from benign prostatic enlargement

Abstract

A group of 107 patients with lower urinary tract symptoms (LUTS) from benign prostatic enlargement (BPE) participated to the HOUSE Study (Home and Office Uroflowmetry Specific Evaluation). Patients received routine investigation, consisting of medical history taking, physical examination including digital rectal examination, prostate-specific antigen (PSA), assessment of symptoms listed both on the International Prostate Symptom Score and on ICS-male questionnaire. We examined the results of uroflowmetry evaluation in this population; data were analysed to observe if any circadian changes of parameters obtained with home uroflowmetry could be detected. We searched a correlation between Q max , Q ave and ICS-benign prostatic hyperplasia symptom score: a significantly inverse correlation was found only for Q max , confirming Q max as a reliable parameter to quantify subjective symptoms. When examining the multiple flow curves recorded in the same patient with home uroflowmetry, voided volume and flow time had usually higher values during night-time: the existence of circadian changes of uroflowmetry parameters in patients with LUTS from BPE was confirmed, and lower values of average and maximum flow rates during sleep hours were recorded in the same patient. In conclusion, when evaluating the natural history or treatment outcome of individual patients or group of patients in clinical trials for evaluation of BPE and LUTS, an assessment including multiple measurements may be useful and of value.

Methods and value of home uroflowmetry in the assessment of men with lower urinary tract symptoms: A literature review

“… Seven home uroflowmeters described in the literature: ( A ) Smith's device,8 ( B ) Streamtest cup,9 ( C ) PEL device,10 ( D ) Uflow Meter®,11, 27 ( E ) Peakometer,12–14 ( F ) P‐flow,16–19 and ( G ) Da Capo 20, 21…”

“…2F),16–19 the Da Capo™, a weight transducer clinic flowmeter adapted for home use (Fig. 2G),20, 21 the PUFS2000,22 and the Home UroData system 23. These devices obtain an automated frequency volume chart along with measurements of the full flow trace and voided volume for multiple voids, without the need for the user to document results.…”

Validation of a novel digital health monitoring system to measure the volume of voided urine

“…Currently, the maximum flow rate is examined at a single time point using uroflowmetry in a medical office. This single measure does not provide a reliable marker of lower urinary tract symptoms, as most patients are unable to relax and void as they usually do . Home uroflowmetry can minimize such hesitation, and thus, provide a more reliable measure of flow rate .…”

Effects of Electroacupuncture on Benign Prostate Hyperplasia Patients with Lower Urinary Tract Symptoms: A Single‐Blinded, Randomized Controlled Trial

“…The Qmax may predict the degree of obstruction in patients with BPH because there is a negative correlation between Qmax and prostate volume [31]. The Qmax is a reliable and objective measurement to evaluate the symptoms of BPH patients, because there is negative correlation between Qmax and the International Continence Society-BPH (ICS-BPH) symptom score [32]. The ICS-BPH symptom score is obtained by using an ICSmale questionnaire, and has a high level of psychometric validity and reliability [33].…”
