Biology and Time Course of Obstruction-Induced Detrusor Underactivity Causing Postvoid Residual Urine.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
To review the time course of muscle mechanics, etiological factors, and molecular mechanisms contributing to the development of postvoid residual urine (PVR), with an emphasis on transcriptomic changes in detrusor underactivity secondary to bladder outlet obstruction (BOO). PVR, the volume of urine remaining in the bladder after micturition, is a key marker of lower urinary tract dysfunction. While often overlooked in routine assessment, it may signal underlying BOO or detrusor underactivity and is associated with serious complications. PVR, bladder physiology and mechanics, and BOO-associated molecular changes were integrated with mRNA expression data from patients with bladder outlet obstruction, as well as from short- and long-term obstructed rat bladders from our own laboratory. Efficient voiding depends on tightly coordinated neural and muscular activity; disruption by elevated outlet resistance, impaired detrusor contractility, or failed coordination can produce residual urine. Chronic BOO and detrusor underactivity are interlinked, with chronic obstruction initiating time-dependent compensatory mechanisms, but ultimately the bladder decompensates. Transcriptomic studies in humans reveal fibroblast-macrophage-epithelial crosstalk driving extracellular matrix remodeling, inflammation, and tissue repair, with conserved molecular pathways across species, including transforming growth factor beta, nuclear factor-kappa B, and phosphoinositide 3-kinase/protein kinase B signaling. Rat models highlight Cthrc1 as a regulator of smooth muscle proliferation after denervation and implicate hypoxia-responsive transcription factors. PVR arises from a multifactorial interplay of timedependent mechanical, myogenic, and neurogenic factors, underpinned by conserved molecular pathways. Molecular diagnostics integrating messenger RNA/microRNA signatures hold promise for early detection of detrusor decompensation, enabling targeted interventions to preserve bladder function and prevent complications.
