Intravesical bacillus Calmette-Guerin is effective in the treatment and prophylaxis of superficial urothelial cancer of the bladder. There have been few reports of its efficacy and toxicity when instilled into the upper urinary tract. We elected to use intracavitary bacillus Calmette-Guerin in a patient with recurrent high grade transitional cell carcinoma in the renal pelvis of a solitary autotransplanted kidney. The patient required hospitalization and triple-drug therapy after 5 instillations. She was free of tumor 1 year after bacillus Calmette-Guerin instillations. 相似文献

Surgical techniques for endoscopic resection of bladder cancer. 总被引:2,自引:0,他引:2
Accompanying the advances in surgical techniques and new intravesical and systemic therapeutic agents for the treatment of individuals with bladder cancer has been the development of greatly improved instrumentation for viewing the interior of the urinary tract and removing neoplasms. Fiberoptic lenses can now be combined with a video system, which enables the urologist to examine the lower urinary tract, not only more easily but with greater magnification. Training is obviously accelerated with the use of video endoscopy. The system also provides the opportunity for documentation and transmittal of the operative findings using either still or motion photography. The endoscopic procedure should be carried out in an orderly fashion. Sufficient lenses and cautery loops must be available to visualize the entire lower urinary tract and to biopsy or resect any abnormality and ensure hemostasis. The urologist should work closely with the pathologist to obtain sufficient cytologic and pathologic material to be confident of the presence or absence of tumor. 相似文献

During a phase III open study of depot leuprolide for stage D2 cancer of the prostate, we studied the effect of depot leuprolide on chronic leuprolide users. To determine whether there was a transient elevation of testosterone or luteinizing hormone (LH) 4-24 h and 3-5 days following the monthly injections, we monitored the changes of testosterone and LH before injection and 24 h post-injection in 10 patients who have been under depot leuprolide Rx for 24-36 weeks, and in 35 patients before injection and 3-5 days post-injection who have received depot leuprolide for 8-24 weeks prior to monitoring. Comparison of the data between pre-injection within 24 h and 3-5 days post-injection showed no significant changes of testosterone and LH values between these levels for either testosterone (P = 0.31) or LH (P = 0.45). We therefore conclude that there was no 'acute on chronic' effect of depot formulation in chronic users of depot leuprolide. 相似文献
