The exact pathophysiology of interstitial cystitis/painful bladder syndrome is unknown; however, autoimmunity is a valid theory. We developed an autoimmune chronic cystitis model by administration of the medium dose of immunogenic peptide T2. Sixty female C57BL/6 mice were divided into six groups. The control group was not treated with any reagent. CFA group was injected with CFA + normal saline, homogenate group with bladder homogenate + CFA, low-dose group with low dose of T2 peptide + CFA, medium dose group with the medium dose of T2 peptide + CFA, and high-dose group with the high dose of T2 peptide + CFA...

OBJECTIVE: Lower urinary tract (LUT) dysfunction is a monumental problem affecting quality of life following neurotrauma, such as spinal cord injury (SCI). Proper function of the bladder and its associated structures depends on coordinated activity of the neuronal circuitry in the spinal cord and brain. Disconnection between the spinal and brain centers controlling the LUT causes fundamental changes in the mechanisms involved in the micturition and storage reflexes. We investigated the effects of cathodal trans-spinal direct current stimulation (c-tsDCS) of the lumbosacral spine on bladder and external urinary sphincter (EUS) functions...

Nephrolithiasis, although a common entity in adults, is less common in children and rare in newborns. The evaluation and management strategies of renal stones in neonates are unclear. We report a rare scenario of renal calculus in a newborn aged 3 days presenting with decreased urine output, fever and crying during micturition. Patient was thoroughly investigated and managed conservatively. Further follow-up showed increase in stone size with recurrent urinary tract infections, hence shock wave lithotripsy was performed to successfully break and clear the stone fragments...

Posterior urethral valves are the most common cause of partial bladder outlet obstruction (PBOO) in the pediatric population. Pathological changes in the bladder developed during PBOO are responsible for long-lasting voiding dysfunction in this population despite early surgical interventions. Increasing evidence showed PBOO induces an upregulation of Hypoxia inducible factors (HIFs) and their transcriptional target genes, and they play a role in pathophysiological changes in the obstructed bladders. We hypothesized that blocking HIF pathways can prevent PBOO-induced bladder dysfunction...

Bladder pheochromocytoma is a rare tumor. The typical manifestations are hematuria, hypertension, headache, sweating, and tachycardia provoked by micturition or overdistention of the bladder. We herein report a case of bladder pheochromocytoma in a 52-year-old woman who presented without micturition attacks. Her clinical course had a latent period of 10 years. A urinary bladder tumor was found incidentally on magnetic resonance imaging. Cystoscopy revealed a large submucosal tumor covered by congested urothelium with a broad base over the left lateral wall of the bladder...

PURPOSE: Management of hydrocolpos in cloaca patients is of clinical importance. We report a nonoperative method for the management of hydrocolpos in the form of initial catheter decompression, followed by an endoscopy with catheters placement into both the bladder and vagina, and leaving these catheters for 9 and 14days respectively. METHODS: The medical records of six cloaca patients with hydrocolpos in the last 12years were reviewed. The outcomes measured were the renal function, bladder emptying, the presence/resolution of hydronephrosis, and the recurrence of hydrocolpos...

BACKGROUND: Percutaneous coronary intervention (PCI) is currently the most common intervention for cardiovascular disease. Standard care after PCI typically involves a period of bed rest in the supine position, but this position creates voiding difficulties. OBJECTIVE: This study aimed to determine whether a modified supine position could facilitate bladder emptying after PCI. METHOD: A randomized controlled trial involving 300 patients was conducted...

Rodents are the main reservoir animals of leptospirosis. In this study, we characterized and quantified the urinary excretion dynamics of Leptospira by Mus musculus infected with 2 × 10(8) virulent Leptospira borgpetersenii serogroup Ballum. Each micturition was collected separately in metabolic cages, at 12 time points from 7 to 117 days post-infection (dpi). We detected Leptospira in all urine samples collected (up to 8 per time point per mouse) proving that Leptospira excretion is continuous with ca. 90% live L...

The lower urinary tract's main functions are storage and elimination. The micturition reflex pathway is modulated by the spinobulbospinal reflex pathway as well as higher brain centers involved in the voluntary micturition control. Micturition is sensitive to numerous injuries, resulting in various types of dysfunction. Animal studies indicate that lower urinary tract dysfunction partly depends on plasticity of the neural pathways. Reflex plasticity is associated with changes in ion channels, receptors, and numerous mediators...

The urinary bladder is a central organ of vertebrates and imposes, based on its extreme deformation (volume changes up to several 100%), special requirements on the overall bladder tissue. However, studies focusing on three-dimensional modelling of bladder deformation and bladder function during micturition are rare. Based on three fields, namely, the membrane potential, calcium concentration, and placement, a mechano-electrochemical-coupled, three-dimensional model describing the contractile behaviour of urinary bladder smooth muscle is presented using a strain energy function...
