OBJECTIVES To determine whether mechanical percussion, diuresis, and inversion (PDI) therapy after shock wave lithotripsy (SWL) improves the clearance rates of lower pole renal stones. METHODS In this single-blind study, 108 patients who underwent SWL treatment for lower pole renal stones with a total diameter of 2 cm or less were prospectively randomized(More)
Intravesical immunotherapy for carcinoma in situ of the bladder is arguably the most effective form of tumour immunotherapy described to date. Following repeated instillations of BCG organisms into the bladder, large quantities of cytokines are detected in patients' urine. This study concerns the production of IL-1 beta, IL-2, IL-4, IL-6, IL-8, IL-10,(More)
BACKGROUND Nuclear p53 and retinoblastoma protein (pRb) were reported to be poor prognostic indicators for transitional cell carcinoma of the bladder. The authors sought to determine the prognostic value of nuclear p53 and pRb in superficial bladder transitional cell carcinoma patients who were treated with intravesical bacille Calmette-Guerin (BCG) or BCG(More)
PURPOSE To determine whether BCG therapy could upregulate interleukin-6 (IL-6) production in human transitional cell carcinomas (TCC). MATERIALS AND METHODS Immunohistochemistry of tumor biopsies and urinary cytospins and ELISA studies of urine from bladder cancer patients and TCC cell-line supernatants, before and after exposure to BCG, were performed.(More)
We report the results of 7 patients with calculi in a horseshoe kidney treated by extracorporeal shock wave lithotripsy (ESWL, 9 renal units) and percutaneous nephrolithotripsy (3 renal units) during a 3-year period. In the ESWL only group complete stone clearance was achieved in only 3 patients (50%) after an average of 3 sessions of therapy. On the other(More)
This meta-analysis evaluated the efficacy and safety of periprostatic nerve block (PPNB) and intrarectal local anesthestic (IRLA) gel in alleviating pain during prostate biopsy. Electronic databases MEDLINE, Cochrane Central Register of Controlled Trials and EMBASE were searched to identify all randomized controlled trials comparing PPNB with periprostatic(More)
Tubulocystic carcinoma of the kidney is a recently reported rare entity, with very few reports in the literature. It has always been described as a low-grade malignancy with favorable prognosis. We report the case of 33-year-old man who presented with back pain. Investigations revealed multiple bony metastases and a large, solid, cystic left renal tumor.(More)
AIMS To determine the expression of intercellular adhesion molecule 1 and 2 (ICAM 1 and 2) in transitional cell carcinoma cells before and after immunotherapy with Calmette-Guérin bacillus (BCG). METHODS Frozen sections from 22 untreated bladder carcinomas were immunohistochemically examined with monoclonal antibodies to ICAM 1 and 2. Urinary cytospin(More)
Intravesical bacillus Calmette-Guerin (BCG) is currently the therapy of choice for superficial bladder cancer with a 60-70% response rate. Induction of cytokine production (e.g. IL-6, etc.) by BCG has been found in patient's urine in vivo as well as bladder cancer cell lines. However, the signalling mechanisms are still unclear. In this study, we(More)
OBJECTIVE Debulking nephrectomy has been shown to improve survival in metastatic renal cell carcinoma and is now a standard procedure. However, it remains controversial if debulking nephrectomy should routinely be followed by interferon. We report on the clinical course of metastatic renal cell carcinoma patients after debulking nephrectomy who did not(More)
