It is a single centre, prospective, interventional study which will offer a vessel for automated measurement of voided volumes of urine. The accuracy of bladder diaries generated by the automated measurement will then be compared to the bladder diaries generated by the conventional eyeballing estimate method of measuring voided volumes.\n\nThe principal objective of this study is to give an answer to the question of whether an automated calculation of voided volumes would produce a more accurate set of data that would be inputted in the bladder diary of the patients and therefore improve the utility and diagnostic ability of this gold standard first line investigation.\n\nStudy Objectives (Aims):\n\nThis project aims to simplify both the collection and analysis; as a result, the test will become simpler to perform, more accurate and helpful to clinicians. It will lead to faster, more accurate assessment of LUTS in women, improving patient satisfaction whilst at the same time providing a cost-effective service.\n\nNull hypothesis:\n\nAutomated measurement of voided volumes and improved accuracy of bladder diary data does not affect utility of bladder diaries.\n\nPrimary outcome of study:\n\nAccuracy of measurement of voided volume with automated device (aim to be within 3%) as defined international standard.\n\nSecondary outcome of study:\n\n1. Outline existing evidence and identify gaps in the knowledge\n2. Outline areas of future development\n3. Educational purposes as it is a student research project\n\nMethods and materials:\n\ni. Study Design: This is a prospective, monocentric, open label, non-randomised, observational study in which the investigators aim to demonstrate error in "eye ball" (traditional method of estimating voided volumes) and increased accuracy of the automated vessel to within the internationally recognized standard of 3% using a flowmeter as the gold standard.\n\nThe investigators will achieve that by:\n\nA. Perform Bench testing. In vitro assessment to demonstrate error in "eye-ball" (traditional method of estimating voided volumes) and increased accuracy to within the internationally recognized standard of 3% using a flowmeter as the gold standard.\n\nB. Recruiting a control group (healthy individual adult women with no lower urinary tract symptoms) to develop more accurate nomograms of bladder function. This will require between 25-50 women of various ages. The control group will be blinded to the automatic cup measurements.\n\nC. Using the tool with women presenting to the Urogynaecology service using the conventional "eye-balling " method and automated uroflowmetry system to assess error from eye-balling and assess how the bladder diary changes comparing the two methods. The investigators would like to recruit approximately 50 patients in each of the following groups: overactive bladder, stress incontinence and prolapse. The groups will be compared using a T test as data are normally distributed. The new nomograms will use ANOVA software and replicate the statistics already established for this. The participants in those groups will be also blinded to the automatic cup measurements generated.\n\nD. Developing Receiver Operating characteristic (ROC) curves for potential diagnostic accuracy tests correlated with increased specificity of voided volumes for future studies.\n\nThis study design has been chosen in order to demonstrate the potential diagnostic benefits of a diary generated by an automated voiding measurement system.\n\nParticipants will be female adults who present in Urogynaecology clinics with lower urinary tract symptoms and require a bladder diary as a first line investigation tool.\n\nRecruitment will take place in the Outpatient Urogynaecology clinic. Women presenting with lower urinary tract symptoms will be identified by the Urogynaecology team in clinic and asked to complete a 3-day paper bladder diary by voiding into the disposable paper jug (as per their usual care). For each void over the 3-day period they will be asked to transfer the voided volume from the disposable paper jug to the diary pod (automated device) which will automatically calculate the voided volume and store the result automatically to the app on their phone. The patient might choose to void first in the automated diary pod and then transfer the voided volume to the conventional paper jag. Both ways are acceptable. The participants will be blinded to those automated measurements as they will not be able to see the volume recorded on the app. All these volumes will be stored in an online electronic portal. The only person with access to the patient\'s portal is the clinician responsible for the research project. At the end of the 3-day period the portal will generate an automated electronic summary of the 3 day diary and this will be compared to the paper diary. The device does not require calibration as it is already pre-calibrated. A patient information leaflet will be handed out to the participants and the risks/benefits and rights to voluntarily participate and withdraw from their study explained. Informed consent will be taken in an outpatient clinic setting after the patient has read the patient information leaflet.'}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Eligibility criteria for females with lower urinary tract symptoms:\n\nInclusion Criteria:\n\n1.
