Treatment with Bacillus Calmette Guerin (BCG) bladder instillations is an established treatment modality for superficial urinary bladder cancer and carcinoma in situ (CIS), but the anti-tumor mechanisms following BCG instillations remain largely unknown. Previous data show increased nitric oxide (NO) concentrations in the urinary bladder from patients treated with BCG suggesting that NO-formation may be involved in the BCG mediated effect. In the present study we evaluated 11 patients with urinary bladder cancer who had received BCG treatment and 11 tumor free control subjects.

The aim of this pilot case-control study was to measure nitric oxide (NO) gas in air incubated in a catheter balloon in the uterus of healthy women and patients with pelvic inflammatory disease, to determine the optimal time of incubation and to find whether NO level rises after manipulation in the uterine cavity. We measured nitric oxide levels in air incubated for 2-10 min in a catheter balloon in the uterine cavity in 6 non pregnant women from 22 to 50 years of age with lower abdominal pain and 10 healthy women with regular menstrual cycles. After an incubation time of just 2 min, intrauterine nitric oxide levels were significantly increased in patients with diagnosed pelvic inflammatory disease compared to healthy women.

Long term catheterization of the urinary tract leads to bacterial colonization of the urine, whereby adherence to the catheter surface is a major determinative factor for colonization. Collection of bacterial isolates from urine and urinary catheters of 45 patients showed multi-species catheter-colonization, while Escherichia coli isolates were frequently found in the urine in high numbers. Biofilm formation of catheter and urine-derived E.

Objective: To evaluate the effect of a single injection of 500 U of botulinum toxin A (BTX-A; Dysport) on use of oral rescue medication, bladder compliance, continence and quality of life in a randomized, placebo-controlled, double-blind study in patients with incontinence due to neurogenic detrusor overactivity. As this group of patients often have severe symptoms, oral tolterodine was allowed as rescue medication and the amount of tolterodine consumed was our primary endpoint.

Material And Methods: A total of 31 patients with urinary leakage due to spinal cord injury, myelomeningocele, trauma at birth, multiple sclerosis and myelitis of another cause were randomized to intravesical injections of either 500 U of BTX-A or placebo.

The urinary tract functions in close proximity to the outside environment, yet must remain free of microbial colonization to avoid disease. The mechanisms for establishing an antimicrobial barrier in this area are not completely understood. Here, we describe the production and function of the cathelicidin antimicrobial peptides LL-37, its precursor hCAP-18 and its ortholog CRAMP in epithelial cells of human and mouse urinary tract, respectively.

Aims/hypothesis: Accumulating evidence indicates that replacement of C-peptide in type 1 diabetes ameliorates nerve and kidney dysfunction, but the molecular mechanisms involved are incompletely understood. C-peptide shows specific binding to a G-protein-coupled membrane binding site, resulting in Ca(2+) influx, activation of mitogen-activated protein kinase signalling pathways, and stimulation of Na(+), K(+)-ATPase and endothelial nitric oxide synthase. This study examines the intracellular signalling pathways activated by C-peptide in human renal tubular cells.

Uterine cervical secretory cells receive a sympathetic cholinergic secretomotor innervation. It has been suggested that glandular nitric oxide (NO) production is a prerequisite for muscarinic-induced carbohydrate secretion in the endometrium and the seminal vesicle. A similar pattern for nerve-induced carbohydrate secretion in the cervix could be assumed.

Insulin stimulates Na(+),K(+)-ATPase activity and induces translocation of Na(+),K(+)-ATPase molecules to the plasma membrane in skeletal muscle. We determined the molecular mechanism by which insulin regulates Na(+),K(+)-ATPase in differentiated primary human skeletal muscle cells (HSMCs). Insulin action on Na(+),K(+)-ATPase was dependent on ERK1/2 in HSMCs.

Purpose: Interstitial cystitis (IC) is one of the most bothersome conditions in urological practice. There are 2 subtypes, classic and nonulcer IC, with similar symptoms but different outcomes with respect to clinical course and response to treatment. Histologically there are fundamental differences between the 2 subtypes, classic IC presenting a severe abnormality of the urothelium and characteristic inflammatory cell infiltrates while inflammation is scant in nonulcer IC.

Purpose: Luminal nitric oxide has been shown to be elevated in the bladder of patients with cystitis of various etiologies. We determine whether luminal nitric oxide can be used as a marker to differentiate inflammation, that is interstitial cystitis, from urgency, frequency, nocturia and pain due to noninflammatory disorders, such as outflow obstruction and neurogenic dysfunction.

Materials And Methods: We measured luminal nitric oxide in the bladder of patients with urgency due to detrusor instability (6), outflow obstruction (7), sensory urge (19) and interstitial cystitis (8), and controls without urgency symptoms (11).
