PURPOSE We review evidence linking overactive bladder (OAB) and interstitial cystitis with anxiety and depression, and highlight the importance of corticotropin releasing factor (CRF) as a potential mediator of these conditions. MATERIALS AND METHODS We review the literature and describe ongoing experiments. RESULTS CRF is expressed in areas of the(More)
OBJECTIVES To determine the cell-specific expression of the two major isoforms of cyclooxygenase (COX-1 and COX-2) in human noncancerous and cancerous prostatic tissues. METHODS Thirty-one specimens of prostate carcinoma (CaP) and 10 specimens of benign prostatic hyperplasia (BPH) were stained with mouse antihuman COX-1 and COX-2 monoclonal antibodies.(More)
In strips of rabbit bladder free of urothelium, the beta-adrenoceptor agonist, isoproterenol, significantly reduced basal detrusor smooth muscle tone and inhibited contractions produced by low concentrations of the muscarinic receptor agonist, carbachol. During a carbachol concentration-response curve, instead of inhibiting, isoproterenol strengthened(More)
INTRODUCTION The purpose of this study was to evaluate the yield of cystoscopy in detecting bladder malignancy following incidentally identified bladder wall thickening observed on computed tomography (CT) scans. METHODS AND MATERIALS Data from 3000 consecutive patients who underwent diagnostic cystoscopy at a single institution from 2006-2009 were(More)
The length-tension (L-T) relationships in airway and vascular smooth muscles have been shown to adapt with length changes over time. Our prior studies have shown that the active and passive L-T relationships in rabbit detrusor smooth muscle (DSM) can adapt and that DSM exhibits adjustable passive stiffness (APS) characterized by a passive L-T curve that is(More)
The length–tension (L–T) relationships in rabbit detrusor smooth muscle (DSM) are similar to those in vascular and airway smooth muscles and exhibit short-term length adaptation characterized by L–T curves that shift along the length axis as a function of activation and strain history. In contrast to skeletal muscle, the length–active tension (L–T a) curve(More)
PURPOSE Bladder wall muscle (detrusor) develops low amplitude rhythmic contractions. Low amplitude rhythmic contraction activity is increased in detrusor from patients with overactive bladder. In this in vitro study we used fast Fourier transforms to assess the length dependence of low amplitude rhythmic contraction components. MATERIALS AND METHODS(More)
STUDY DESIGN Retrospective study. OBJECTIVES The purpose of this investigation was to review the outcomes and safety of retrograde ureteroscopic laser lithotripsy (URS) for the treatment of urolithiasis in the spinal cord injury (SCI) population. SETTING Virginia, USA. METHODS All patients with SCI who underwent URS with holmium:YAG laser lithotripsy(More)
Urinary diversion is a surgical technique to redirect the stream of urine, most often after cystectomy. Cystectomy may be performed both for benign and for malignant conditions. Bladder cancer is the most common indication for cystectomy, and most patients who undergo radical cystectomy and urinary diversion have muscle-invasive or high-risk(More)
Interstitial cells of Cajal (ICCs) have been identified as pacemaker cells in the upper urinary tract and urethra, but the role of ICCs in the bladder remains to be determined. We tested the hypotheses that ICCs express cyclooxygenase (COX), and that COX products (prostaglandins), are the cause of spontaneous rhythmic contraction (SRC) of isolated strips of(More)
