bladder/hypoxia

OBJECTIVE To examine the correlation between partial bladder outlet obstruction (PBOO) and bladder carcinogenesis. METHODS Female Wistar rats (6 weeks old) were divided into three groups of 10 each: group 1 was exposed to n-butyl-n-butanol nitrosamine (BBN, a carcinogen) in drinking water for 8

Ischemia and the accompanied hypoxia significantly impair the function of the urinary bladder, which is further damaged by ischemia/reperfusion (I/R) injury following the re-establishment of the blood supply. Current evidences have confirmed that blood flow of the bladder is decreased by bladder

OBJECTIVE Recent animal studies have suggested that bladder outflow obstruction causes bladder wall hypoxia during both the filling and the voiding phases of the micturition cycle. We have previously demonstrated that mechanical deformation of human detrusor leads to smooth muscle (SM) cell

OBJECTIVE To study the relationship between hypoxia and metallothionein expression in bladder biopsies of interstitial cystitis/painful bladder syndrome patients. METHODS The study group consisted of 41 patients with interstitial cystitis/painful bladder syndrome, and the control group consisted of

OBJECTIVE Posterior urethral valves are the most common cause of partial bladder outlet obstruction in the pediatric population. However, to our knowledge the etiology and the detailed mechanisms underlying pathological changes in the bladder following partial bladder outlet obstruction remain to be

The ability to repair damaged urinary bladders through the application of bone marrow-derived cells is in the earliest stages of development. We investigated the application of bone marrow-derived cells to repair radiation-injured bladders. We used a three-dimensional bioprinting robot system to

OBJECTIVE Several studies suggest that hypoxia of the bladder wall contributes to bladder dysfunction but the exact relation between bladder function and blood oxygen saturation, a surrogate marker for hypoxia, is not known. We determined bladder wall blood oxygen saturation in vivo in an animal

OBJECTIVE To provide insights into the pathogenesis of bladder insult secondary to bladder outlet obstruction. METHODS Six-week-old female Sprague-Dawley rats (n = 80) were divided into eight groups, 10 rats each, according to the duration of bladder outlet obstruction, including 0, 3, 6, 12, 24,

Previous studies have demonstrated that the ability of the in vitro whole bladder to empty in response to bethanechol administration was inhibited by anoxia while its ability to generate pressure decreased only slightly. One question was not addressed by these early studies: Is the anoxic effect

OBJECTIVE Patients with localized muscle-invasive bladder cancer (MIBC) can choose to undergo either neoadjuvant chemotherapy followed by radical cystectomy or radiation therapy-based bladder preservation treatment modality with subsequent close cystoscopic surveillance with salvage cystectomy

OBJECTIVE Mesenchymal stem cells have various therapeutic benefits in various organ injury models. Bladder outlet obstruction causes smooth muscle hypertrophy and fibrosis, leading to lowered compliance, increased storage pressures and renal injury. Decreased blood flow and hypoxia may contribute to

OBJECTIVE The main objective of the present study was to evaluate the presence of overactive bladder (OAB) syndrome, nocturia, urgency, and urge incontinence in patients with obstructive sleep apnea syndrome (OSAS), and measure bladder wall thickness (BWT) in these patients. METHODS The patient

Three cases of gall bladder distention in asphyxiated newborns are described. Clinical and ultrasound examination showed this to be a benign, transient phenomenon. A causal relation between tissue hypoxia and gall bladder distention is proposed.
