BACKGROUND AND PURPOSE Robot-assisted partial nephrectomy has emerged as a viable surgical treatment for patients with certain renal tumors. We hypothesized that extirpation of more complex tumors, as graded with the nephrometry score, would result in worse operative and postoperative outcomes when compared with tumors with lower nephrometry scores. We(More)
PURPOSE A retrospective review of preoperative three-dimensional (3D) CT and the operative findings during laparoscopic donor nephrectomy. PATIENTS AND METHODS Fifty-four consecutive patients underwent laparoscopic donor nephrectomy. Of these patients, 51 had preoperative 3D reconstructed CT scans. Each radiologic report was compared with the operative(More)
Retrograde ureteroscopy has recently gained a broadened indication for use from diagnostic to a variety of complex minimally invasive therapies. This review aims to look at the recent advances in the instrumentation and accessories, the widened indications of its use, surgical techniques and complications. With minimization of ureteroscopic instruments(More)
BACKGROUND Prostate cancer remains the most common malignancy among elderly men and the second leading cause of cancer death in the United States. Although several conventional therapies are currently available, they have a low efficacy and the more effective treatment modalities need to be established. Interferons (IFNs) are one of such options known as(More)
OBJECTIVE To examine whether the combination of interferon (IFN)-alpha and maitake mushroom D-fraction (PDF), a bioactive mushroom extract, might potentiate the anticancer activity of IFN-alpha in bladder cancer T24 cells in vitro. MATERIALS AND METHODS Effects of recombinant IFN-alpha(2b) (0-50 000 IU/mL), PDF (0-700 microg/mL), or their combinations(More)
Androgen ablation is one of the viable therapeutic options for patients with primary hormone (androgen)-dependent prostate cancer. However, an antibiotic brefeldin A (BFA) has been shown to exhibit the growth inhibitory effect on human cancer cells. We thus investigated if BFA might inhibit proliferation of androgen-responsive prostate cancer LNCaP cells(More)
OBJECTIVE To investigate the cytotoxic action of nephrotoxic agents using an in vitro renal cell model, focusing on the cellular oxidative status and a specific glutathione (GSH)-dependent enzyme, glyoxalase I (Gly-I). MATERIALS AND METHODS Renal proximal tubular LLC-PK(1) cells were exposed to mercuric chloride, glycerol, cisplatin, gentamicin and(More)
BACKGROUND AND PURPOSE An integral component of many urologic reconstructive surgical procedures is the positioning of a Double-J stent to span the anastomosis. Some surgeons prefer to place a retrograde stent during cystoscopy, either during or after the reconstruction. In this communication, we describe our straightforward and effective approach of(More)
Superficial bladder tumors are the most prevalent form of bladder cancers and transurethral resection is the primary surgical modality for those tumors. However, nearly 65% of patients will have tumor recurrence in five years while about 15% will have progression to muscle invasion. Thus, the primary therapeutic aim is to prevent multiple recurrences and(More)
