Urodynamic tests are the gold standard for the diagnosis of bladder dysfunction, and the mechanical compliance of the bladder is an important parameter in these tests. The bladder wall has a layered structure, differentially affected by pathology, so knowledge of the contribution and role of these layers and their constituents to overall bladder compliance will enhance interpretation of these clinical tests. In this study we document the functional morphology of the detrusor and lamina propria of the murine bladder wall using a custom in-situ tensile loading system under multiphoton microscopy (MPM) observation in unloaded state and under incremental uniaxial stretch...

Transabdominal and transvaginal sonography are used to measure bladder wall and detrusor thickness. Only transvaginal sonography has been used to measure the vaginal wall thickness. We describe the use of transabdominal sonography to measure the total vaginal wall thickness and total vaginal mucosal thickness at the bladder trigone. The mean bladder wall thickness and SD from published data were within the 95% confidence interval of our data. Total vaginal and mucosal thicknesses are reliable measurements, which require specific evaluation in a postmenopausal population...

Urinary bladder activity involves central and autonomic nervous systems and bladder wall. Studies on the pathogenesis of voiding disorders such as the neurogenic detrusor overactivity (NDO) due to suprasacral spinal cord lesions have emphasized the importance of an abnormal handling of the afferent signals from urothelium and lamina propria (LP). In the LP (and detrusor), three types of telocytes (TC) are present and form a 3D-network. TC are stromal cells able to form the scaffold that contains and organizes the connective components, to serve as guide for tissue (re)-modelling, to produce trophic and/or regulatory molecules, to share privileged contacts with the immune cells...

INTRODUCTION: Upper tract damage (UTD) is a life-threatening complication of neurogenic bladder (NB). Early identification of risk factors for UTD and institution of remedial measures may probably prevent UTD. The aim was to study the predictors of UTD in children 2 years or older with NB. METHOD: This cross-sectional, observational study over 2 years included 30 children. UTD was defined as serum creatinine of >1 mg/dL or society of fetal urology grade III-IV hydronephrosis or hydroureteronephrosis on ultrasonography or renal scars on (99)(m)technetium dimercaptosuccinic scan or subnormal glomerular filtration rate (GFR) for age...

The role of ultrasound imaging in urogynecology is not clearly defined. Despite significant developments in visualization techniques and interpretation of images, pelvic ultrasound is still more a tool for research than for clinical practice. Structures of the lower genitourinary tract and pelvic floor can be visualized from different approaches: transperineal, introital, transvaginal, abdominal or endoanal. According to contemporary guidelines and recommendations, the role of ultrasound in urogynecology is limited to the measurement of post-void residue...

PURPOSE: Detrusor underactivity (DU) has lately gained increasing interest because this bladder condition is an important cause of post-void residual urine and lower urinary tract symptoms (LUTS) in adult men. Until now, DU can only be diagnosed by pressure-flow measurement. Therefore, the aim of this study was to search for noninvasive tests which can safely predict DU in adult men. METHODS: Unselected, treatment-naïve male patients aged ≥40 years with uncomplicated, non-neurogenic LUTS were prospectively evaluated...

PURPOSE: Shuttling of some of the bladder volume into the bladder diverticulum (BD) can cause urinary retention, lower urinary tract dysfunction, infection, and stone formation. This experimental study is the first to create a rabbit BD to study micturition physiology (urodynamics and pathology) that mimics clinical findings. MATERIALS AND METHODS: The study included 16 New Zealand adult male rabbits in the BD group and 16 sham-operated controls. BD creation consisted of a lower midline laparotomy and bladder entry via the spacing between the detrusor muscle fibers and the mucosa, posterolaterally from the bladder wall...
