Aims: Lower urinary tract (LUT) sensations form an essential part of diagnostic criteria for many LUT symptoms, additionally LUT sensations are used to evaluate the effectivity of therapeutic interventions. The accurate measurement of LUT sensations, however, is severely hampered by the subjective nature of these sensations.
Methods: This paper summarizes the discussions from the 2024 meeting of the International Consultation for Incontinence-Research Society (ICI-RS 2024) regarding systematic evaluations of LUT sensations and the design of more objective tools to measure these.
Results: Here, we discuss factors that influence sensations that are under the control of the caregiver/investigator, the signaling of sensations from the LUT toward the central nervous system, and currently used diagnostic tools to measure LUT sensations. Recent methodological advances to objectively measure factors that correspond with changes in LUT sensations are introduced along with recommendations for future research to optimally enable objective assessment of processes underlying LUT sensations.
Conclusions: Advancing the objective measurement of LUT sensations will require interdisciplinary collaboration, integrating insights from neuroscience, engineering, and clinical practice. Such efforts hold the potential to transform patient care by enabling more precise diagnostics and personalized therapeutic strategies.

Article Synopsis
- - The review discusses how central nervous system centers influence the function of lower urinary and anorectal tracts, emphasizing how spinal cord dysfunction can disrupt these systems due to various mechanisms.
- - Key topics from a workshop highlighted important research questions regarding the evaluation of the levator ani muscle, sensory function, and the use of functional imaging to improve clinical assessment and treatment for spinal dysfunction.
- - The conclusion stresses the need for comprehensive evaluations and innovative clinical approaches to effectively address the impact of spinal cord dysfunction on lower urinary and anorectal tract functions, while also identifying the importance of preclinical research in this area.

Objectives: Neuroimaging studies have advanced our understanding of the intricate central nervous system control network governing lower urinary tract (LUT) function, shedding light on mechanisms for urine storage and voiding. However, a lack of consensus in methodological approaches hinders the comparability of results among research groups and limits the translation of this knowledge to clinical applications, emphasizing the need for standardized methodologies and clinical utilization guidelines.
Methods: This paper reports the discussions of a workshop at the 2023 meeting of the International Consultation on Incontinence Research Society, which reviewed uncertainties and research priorities to progress the field of neuroimaging in LUT control and dysfunction.

IC/BPS is a chronic inflammatory pelvic pain syndrome characterized by lower urinary tract symptoms including unpleasant sensation (pain, pressure, or discomfort) in the suprapubic or bladder area, as well as increased urinary frequency and urgency, and decreased bladder capacity. While its etiology remains unknown, increasing evidence suggests a role for changes in nerve growth factor (NGF) signaling. However, NGF signaling is complex and highly context dependent.
