“…A limitation of this study was that the sample comprised only English‐speaking Australians and thus care should be taken when extrapolating the results of this study cross culturally or internationally in jurisdictions where English is not spoken or where different variations of the English language are used. Nevertheless, the language categories developed in this study are consistent with previous reports of both recalled and induced urge/urgency sensations from countries including the United Kingdom, United States of America, and the Netherlands (Dutch language translated into English) . Recently published studies have provided some detail on the derivation of descriptors, such as use of focus groups, or interviews, whereas earlier studies appear to have derived descriptors from authors' clinical experience, or from previously published summaries of sensation .…”

“…In contrast to previous studies, the current study provides evidence that differences exist in the language used by individuals with and without OAB. Heeringa et al reported that patients with OAB volunteered similar descriptors of sensation as healthy participants. However, their focus group methodology was an iterative process, where participants shared ideas to consensus.…”

“…Although many of the biomechanical properties require both urodynamic (pressure) and ultrasound (geometric) data, volume and perimeter strain only require geometric data and had the best correlation to sensation. These parameters can be measured by taking serial ultrasound measurements throughout filling induced by non-invasive oral hydration (De Wachter et al, 2014; Heeringa et al, 2012; Heeringa et al, 2012; Nagle et al, 2016). Measuring perimeter strain only requires the luminal area to be traced, which could potentially be accomplished automatically using edge detection; therefore, this parameter has high potential to be developed as a stand-alone noninvasive test or screening tool used before urodynamics.…”

Overactive bladder is often characterized by biomechanical changes in the bladder wall, but there is no established method to measure these changes in vivo. The goal of this study was to develop a novel method to determine detrusor wall biomechanical parameters during urodynamics through the incorporation of transabdominal ultrasound imaging. Individuals with overactive bladder (OAB) underwent ultrasound imaging during filling. The fill rate was 10% of the cystometric capacity per minute as determined by an initial fill. Transabdominal ultrasound images were captured in the midsagittal and transverse planes at 1 min intervals. Using image data and Pves, detrusor wall tension, stress, and compliance were calculated. From each cross−sectional image, luminal and wall areas along with inner perimeters were measured. In the sagittal and transverse planes, wall tension was calculated as Pves*luminal area, wall stress as tension/wall area, and strain as the change in perimeter normalized to the perimeter at 10% capacity. Elastic modulus was calculated as stress/strain in the medial-lateral and cranial-caudal directions. Patient-reported fullness sensation was continuously recorded. Data from five individuals with OAB showed that detrusor wall tension, volume, and strain had the highest correlations to continuous bladder sensation of all quantities measured. This study demonstrates how detrusor wall tension, stress, strain, and elastic modulus can be quantified by adding ultrasound imaging to standard urodynamics. This technique may be useful in diagnosing and better understanding the biomechanics involved in OAB and other bladder disorders.

“…Due to the invasiveness, patient risk, and cost of this test, non‐invasive hydration protocols have been developed to characterize real‐time bladder sensation in patients with and without OAB . Some of these studies have used a tablet‐based sensation meter that participants used to track real‐time, unprompted bladder sensation .…”

Objectives A non‐invasive protocol was previously developed using three‐dimensional ultrasound and a sensation meter to characterize real‐time bladder sensation. This study the protocol by measuring the effects of fill rateand ultrasound probe pressure during oral hydration. Methods Healthy volunteers with no urinary symptoms (based on International Consultation on Incontinence Questionnaire on Overactive Bladder surveys) were recruited into an oral hydration study. Throughout two complete fill–void cycles, participants drank 2 L Gatorade G2 (The Gatorade Company, Inc., Chicago, Illinois) and used a touch‐screen sensation meter to record real‐time bladder sensation (0%‐100%). The study was repeated three times, once per week (Visits A, B, and C). In Visits A and B, ultrasound was used to measure bladder volume every 5 minutes. Ultrasound was not used in Visit C except at 100% capacity. Volume data from Visit B were used to estimate volumes throughout the fills in Visit C. Sensation–capacity curves were generated for each fill for comparative analysis. Results Ten participants completed three visits (60 total fills). Increased fill rate led to decreased sensation throughout filling, andultrasound probe pressure led to increased sensation. Participants reported higher sensation at low volumes during Fill 1 of Visit A before training with the sensation meter. Sensation curves with intermittent ultrasound showed repeatability for Fill 2 in Visits A and B. Fill rate and ultrasound probe pressure affect real‐time bladder sensation during oral hydration. Conclusions This study demonstrated repeatability of real‐time bladder sensation during a two‐fill oral hydration protocol with ultrasound.
