Clean intermittent catheterisation (CIC) of the bladder is used to imitate normal bladder emptying in patients with bladder dysfunction. CIC is associated with urinary tract infection (UTI) that may be difficult to treat in the case of antimicrobial resistance. The aim of this study was to establish the effect and safety of intravesical gentamicin treatment in such settings. In 2009, intravesic...

The impact of intravesical chemotherapy prophylaxis on recurrence of superficial transitional cell carcinoma of the bladder is poorly defined. The objective of this report is to present a meta-analysis of the available clinical trial data to quantify the effect of intravesical chemotherapy on tumor recurrence following complete transurethral resection (TURB) in patients with newly diagnosed sup...

PURPOSE Temporary drainage of the upper urinary tract by use of internal ureteral stents is a common procedure that is often associated with a variety of symptoms. The role of intravesical stent position in associated morbidity is controversial. MATERIALS AND METHODS The German version of the ureteral stent symptom questionnaire (USSQ) was completed by 73 patients with an indwelling ureteral ...

BACKGROUND Urothelial carcinoma (UC) is a common cancer affecting many patients in the United States. Nephroureterectomy remains the gold standard for the treatment of high grade upper tract disease or low grade tumors that are not amenable to endoscopic management. Recent reports have shown a decrease in UC recurrence in patients who underwent nephroureterectomy and who had Mitomycin C (MMC) i...

Background: To study the prevalence of significant Intravesical Prostatic Protrusion (IPP) in patients presenting with acute urinary retention (AUR) due to Benign prostatic hyperplasia (BPH) and correlation between intravesical protrusion volume.Methods: We assessed 68 men ages 45 85 who presented retention. Initial assessment included detailed clinical history, International Prostate Symptom S...

A novel method for evaluating the urethral resistance during abrupt elevation of abdominal pressure was developed in spinalized female rats under urethane anesthesia. Electrical stimulation of abdominal muscles for 1 s induced increases in both the intra-abdominal and the intravesical pressure in a stimulus-dependent manner, and the bladder response was almost lost when the abdomen was opened. ...

Background: The high incidence of tumor recurrence following transurethral resection (TUR) continues to represent a major problem encountered in the treatment of bladder cancer. This study examined the limited efficacy of intravesical chemotherapy in superficial bladder cancer. Methods: Subjects comprised 90 cases with low-grade superficial transitional cell carcinoma who were rendered tumor-fr...

This study aimed to develop an intravesical delivery system of gemcitabine HCl for superficial bladder cancer in order to provide a controlled release profile, to prolong the residence time, and to avoid drug elimination via urination. For this aim, bioadhesive nanoparticles were prepared with thiolated chitosan (chitosan-thioglycolic acid conjugate) and were dispersed in bioadhesive chitosan g...

Macrophage migration inhibitory factor (MIF) mediates pain although the mechanisms are not well understood. Urothelial activation of protease activated receptor 4 (PAR4) results in urothelial MIF release, urothelial high mobility group box 1 (HMGB1) release and bladder pain in mice without bladder inflammation. All three effects are prevented by MIF inhibition while intravesical disulfide HMGB1...

BACKGROUND The effect of intravesical instillation of doxorubicin or epirubicin after transurethral resection (TUR) was estimated from the data of five randomized clinical trials in Japan. The authors provided the estimated hazard function plots with a smoothing technique, to evaluate the prophylactic effect of an intravesical therapy over time and to estimate the natural history of superficial...
