The objective of this study was to evaluate the intravesical application of N-(4-hydroxyphenyl) retinamide (4-HPR) and adriamycin (ADM), as a treatment modality in a an animal model of chemically-induced bladder cancer. Bladder cancer developed in 50.0% of female Wistar rats, 4-6 weeks after intravesical application of the chemical carcinogen, N-methyl-N-nitrosourea (MNU). There was no signific...

The efficacy of intravesical onabotulinumtoxinA (BTXA) in the treatment of overactive bladder (OAB) has been well documented. The use of BTXA injection in orthotopic neobladders is yet to be studied. We present 4 cases of patients injected with intravesical BTXA for overactive orthotopic ileal neobladder. We recorded patient demographics, presenting and follow-up symptoms, urodynamic profiles, ...

PURPOSE SUI (Stress Urinary Incontinence) results from sudden increases in intravesical peak pressures exceeding urethral resistance leading to involuntary urine loss. Obesity and smoking are well established reversible risk factors for SUI and may alter intravesical peak pressures. BMI, smoking status, and other clinical factors were studied to determine their relationship to CIPP (maximal Int...

Intravesical onabotulinumtoxinA (BoNT-A) injection is an effective treatment for overactive bladder syndrome (OAB) that is refractory to antimuscarinics. An injectable dose of 100 U has been suggested to achieve the optimal balance of benefit and safety in patients with OAB. BoNT-A (total volume of 10 mL) was administered as evenly distributed intradetrusor injections (5 U) across 20 sites appr...

Objectives: We present our innovative technique of excising intravesically exposed mesh resulting from anti-incontinence sling procedures using transurethral thulium laser assisted by a suprapubic transvesical mini-laparoscopic grasper. Methods: Two patients agreed to anti-incontinence sling surgery for stress urinary incontinence several years ago prior to presentation. Because of symptom recu...

The mechanism by which transitional tumor cells adhere to areas of urothelial injury and the means by which heparin prevents this phenomenon were studied. Scanning electron microscopy and a radiolabeled tumor cell adherence assay were used to assess the activity of heparin and a "nonglycosaminoglycan" thrombolytic agent, recombinant tissue plasminogen activator, in preventing tumor cell adheren...

Vesicoureteric reflux was produced in eight piglets by opening their bladders and slitting the anterior intravesical wall of the ureter. Cystography confirmed the presence of bilateral reflux in six piglets and unilateral reflux in two. Six to eight weeks later the bladder was again opened and Teflon paste injected in the space behind the intravesical ureter, thereby creating a support for the ...

Intravesical application of an anti-inflammatory drug is an efficient strategy for acute cystitis therapy. Quercetin (QU) is a potent anti-inflammatory agent; however, its poor water solubility restricts its clinical application. In an attempt to improve water solubility of QU, biodegradable monomethoxy poly(ethylene glycol)-poly(ɛ-caprolactone) (MPEG-PCL) micelles were used to encapsulate QU b...

INTRODUCTION The aim of this study was to examine the efficacy and safety of intravesical Bacillus Calmette-Guerin (BCG) in the treatment of refractory interstitial cystitis (IC). MATERIALS AND METHODS Thirteen patients with refractory IC were enrolled in the study. They were scheduled to receive 6 weekly courses of treatment with intravesical BCG. Variables including the frequency, nocturia,...

OBJECTIVES We reviewed our experience with partial cystectomy to assess local control and survival rates, and to identify pathologic predictors for recurrence. METHODS From 1995 to 2005, 25 patients with urothelial carcinoma underwent partial cystectomy with curative intent. As protocol, patients with primary solitary muscle-invasive bladder tumors underwent preoperative localized radiotherap...
