BACKGROUND Systemic administration of cannabinoid agonists is known to reduce pain induced by bladder inflammation and to modulate cystometric parameters in vivo. We have previously reported that intravesical administration of a cannabinoid agonist reduces the electrical activity of bladder afferents under normal conditions. However, the effects of local activation of bladder cannabinoid recept...

PURPOSE Painful bladder syndrome/interstitial cystitis (PBS/IC) is a disabling disease of the urinary bladder, and its etiology and treatment are not yet established. Current medications used in the treatment of PBS/IC have shown limited efficacy. This prospective study investigated the efficacy of intravesical resiniferatoxin (RTX) in PBS/IC refractory to medical treatment. METHODS Patients ...

PURPOSE In this study, we investigated the ability of UroVysion to assess response to intravesical therapy in patients with high risk superficial bladder tumors. MATERIALS AND METHODS We performed a retrospective review of patients undergoing intravesical therapy for high risk superficial bladder tumors. Urine specimens were collected for UroVysion analysis before and immediately after a cour...

AIMS Glycosaminoglycan (GAG) layer replenishment is a cornerstone in the therapy of interstitial cystitis (IC). During the last years intravesical GAG layer replenishment has proven to be an effective treatment for overactive bladder (OAB), radiation cystitis, and recurrent urinary tract infections (UTIs). METHODS Examination of different substances available for intravesical GAG replenishmen...

Intravesical administration of cytotoxic agents is commonly used in urological practice for treatment of superficial bladder cancer. The leading motive is optimisation of drug delivery near the site of action and reduction of systemic toxicity. Bladder pharmacokinetics is complicated by several mechanisms. The objectives of this work were to develop a kinetic model of drug distribution in the b...

An 84-year-old man with no evidence of pre-existing interstitial pneumonia developed fatal interstitial pneumonia and respiratory failure that could only be explained as an adverse effect of intravesical mitomycin C chemotherapy. He had undergone transurethral resection of bladder cancer 3 times, followed by intravesical mitomycin C chemotherapy 1 month later. He had received intravesical mitom...

Intravesical Bacillus Calmette Guerin (BCG) immunotherapy is the standard initial therapy for patients with high-grade urothelial bladder cancer without muscle invasion. While minor complications due to intravesical BCG immunotherapy are common, cutaneous infections of the glans penis are quite rare. Granulomatous balanitis can be devastating if not identified and treated early. A well-establis...

PURPOSE We investigated the effect of propiverine on cystometric parameters based on intraabdominal pressure (IAP) in awake rats in an overactive bladder (OAB) model induced by intravesical instillation of prostaglandin E(2) (PGE(2)). MATERIALS AND METHODS Twenty-two female Sprague-Dawley rats were used. Polyethylene catheters were implanted into the bladder to record the intravesical pressur...

AIMS To demonstrate the effects of intravesical ozone treatment on inflammation and epithelial cell damage in chemical cystitis animal model. MATERIALS AND METHODS A total of 30 New Zealand rabbits were divided into six groups. Cystitis was conducted with transurethral intravesical hydrochloric acid instillation on the subjects in Groups IA, IB, IIA, and IIB. Then, Group IA-IB subjects were t...

The surgical treatment of vesicoureteral relfux can range from injection therapy to open ureteral reimplantation. Minimally invasive applications for treatment of vesicoureteral relfux include laparoscopic extravesical and intravesical ureteral reimplantation. We present our extended experience of the technique for intravesical cross-trigonal ureteral reimplantation for vesicoureteral relux.
