OBJECTIVES To detail, in a review, one institution's 6-year experience using botulinum toxin A (BTX-A) in the bladder and urethra in 110 patients for a variety of lower urinary tract disorders. METHODS A total of 110 patients (35 men and 75 women, age range 19 to 82 years) received injections of BTX-A into the bladder (n = 42) or urethra (n = 68). Voiding(More)
OBJECTIVES To investigate the effects of intravesical application of adenosine 5'-triphosphate (ATP) on bladder activity to elucidate the role of urothelial barrier function and ecto-ATPase activity in the ATP-mediated mechanism inducing detrusor overactivity. METHODS Continuous cystometry by an intravesical catheter inserted from the bladder dome was(More)
OBJECTIVES To perform a randomized comparative study to investigate the clinical effects of extracorporeal magnetic innervation (ExMI) and functional electrical stimulation (FES) on urinary incontinence after retropubic radical prostatectomy. METHODS Thirty-six patients with urinary incontinence after radical prostatectomy were randomly assigned to three(More)
A fragment of HeLa cell mitochondrial DNA containing the origin of replicaton has been sequenced. The precise position of the origin in this sequence has been identified by determining the nucleotide order in the 5'-end proximal portion of the heavy strand initiation fragment (7S DNA), and by aligning the two sequences.
BACKGROUND Extracorporeal magnetic innervation (ExMI) is a new technology used for pelvic muscle strengthening for the treatment of stress urinary incontinence. We explored whether this new technology is effective for patients with urge incontinence, as well as those with stress urinary incontinence. METHODS We studied 20 patients with urge incontinence(More)
OBJECTIVE To investigate the effects of the selective phosphodiesterase (PDE) type 4 inhibitor IC485 and the widely used antimuscarinic drug tolterodine tartrate on bladder activity in rats with bladder outlet obstruction (BOO), as inhibition of PDE4 leads to elevation of intracellular cAMP levels and relaxation of smooth muscle. MATERIALS AND METHODS BOO(More)
OBJECTIVE To investigate the effects of a selective type 4 cyclic nucleotide phosphodiesterase (PDE4) inhibitor, IC486051, on bladder activity in normal rats and those with and bladder outlet obstruction (BOO), as inhibition of PDE4 leads to elevation of intracellular cAMP levels and relaxation of smooth muscle. MATERIALS AND METHODS BOO was induced in(More)
In order to clarify the functional role of the isolectin B4 (IB4)-binding afferent pathway in the micturition reflex, we investigated the effects on bladder activity of intrathecal application of the IB4-saporin conjugate, a targeting cytotoxin that destroys neurons binding IB4. In rats, IB4-saporin (2.5 micro m) or vehicle was administered through an(More)
OBJECTIVES To evaluate the clinical outcome of nephroureterectomy with endoscopically assisted transurethral ureteral stripping for transitional cell carcinoma of the renal pelvis in a comparative study. METHODS Sixty patients with localized renal pelvic cancer were enrolled in a prospective comparative nonrandomized study. Of these, 28 patients underwent(More)
