A 59 year old male presented with a 4 month history of lower urinary tract symptoms. Exhaustive urological investigations revealed papillary tumors and carcinoma in situ extending from the prostatic urethra, throughout the bladder, up both ureters and into the renal pelves. Tumors were resected where possible and then bacillus Calmette-Guèrin (BCG) and mitomycin C (MMC) were infused sequentially through bilateral nephrostomy tubes for a total of six BCG and three MMC instillations.

We aimed to do a prospective, randomised comparison of BCG alone with that of sequential BCG and electromotive mitomycin in patients with stage pT1 bladder cancer.
Methods: After transurethral resection and multiple biopsies, 212 patients with stage pT1 bladder cancer were randomly assigned to: 81 mg BCG infused over 120 min once a week for 6 weeks (n=105); or to 81 mg BCG infused over 120 min once a week for 2 weeks, followed by 40 mg electromotive mitomycin (intravesical electric current 20 mA for 30 min) once a week as one cycle for three cycles (n=107).
Purpose: We investigated the effectiveness and safety of intravesical resiniferatoxin (Sigma Chemical Co., St. Louis, Missouri) and botulinum-A toxin injections into the detrusor muscle in a group of spinal cord injured patients with neurogenic detrusor overactivity unresponsive to conventional anticholinergic therapy.

We performed a prospective controlled study to assess the efficacy of intraplaque electromotive verapamil/dexamethasone vs electromotive lidocaine.
Materials And Methods: Patients with Peyronie's disease were randomized into a study group (47 patients) and a control group (49 patients).
Purpose: In laboratory studies electromotive mitomycin C (MMC) demonstrated markedly increased transport rates compared with passive transport. We performed a prospective study in patients with high risk superficial bladder cancer to assess the efficacy of intravesical electromotive vs passive MMC using bacillus Calmette-Guerin (BCG) as a comparative treatment.
Materials And Methods: Following transurethral resection and multiple biopsies 108 patients with multifocal Tis, including 98 with T1 tumors, were randomized into 3 equal groups of 36 each who underwent 40 mg electromotive MMC instillation with 20 mA electric current for 30 minutes, 40 mg passive MMC with a dwell time of 60 minutes or 81 mg BCG with a dwell time of 120 minutes.
Intravesical electromotive administration of local anesthetics is clinically successful but electrochemistry, cost and effectiveness limit the choice of drugs to diluted lidocaine HCl 4% mixed with epinephrine. These studies address the stability of lidocaine and epinephrine both over time and when exposed to electric current, i.e.
