99m technetium sulfur colloid scanning in diagnosis of renal transplant rejection.

To evaluate the possible presence of rejection 37 99mtechnetium sulfur colloid imaging procedures were done on 17 renal transplant patients. There was good correlation between the clinical diagnosis and the results of the technetium sulfur colloid images, with no falsely positive studies in the series. An illustrative case and a review of pertinent literature confirm this technique to be an excellent method for the early detection of renal transplant rejection.

Adenocarcinoma of rete testis.

Adenocarcinoma of the rete testis is a rare tumor of the genital tract. An advanced case of adenocarcinoma thought to arise from the rete testis is presented. We believe this is the eighteenth reported case.

Extraosseous myelomatosis. Clinical presentation with symptoms in lower urinary tract.

We believe this to be the first case reported of extraosseous myelomatosis seen clincally with lower urinary tract symptoms. Extraskeletal spread of myelomatosis which reportedly occurs in two thirds of cases is discovered postmortem. Immunoglobulin A prevails in this type of myelomatosis. Clinical course and autopsy findings are discussed.

The impact of 5-alpha-reductase inhibitors on the number of prostatectomies for benign prostatic hyperplasia.

To determine the impact of a 5-alpha-reductase inhibitor on the need for surgical treatment of symptomatic benign prostatic hyperplasia (BPH) in clinical urologic practice, we retrospectively reviewed records of 794 patients treated with pharmacotherapy or surgery (or both). The number of transurethral resections of the prostate (TURPs) performed during the 30 months since introduction of finasteride was compared with the number performed during the 30 months before finasteride became available. The alpha-blockers doxazosin and prazosin were used during both times for the treatment of BPH. Of the 619 patients treated with drugs, 88.5% received finasteride for a mean of 249.6 days. The alpha-blockers, either alone or combined with finasteride, were prescribed for 11.5% of patients for a mean of 179 days. In the 30 months after the introduction of finasteride, 65 patients underwent TURP: 28 of these men had initially received drug therapy. In contrast, 138 TURPs were performed in the 30 months prior to the availability of finasteride. The use of a 5-alpha-reductase inhibitor as primary medical therapy for symptomatic BPH decreased the number of prostatectomies by 52.9% (65 vs 138). This observation warrants corroboration through additional prospective studies.

Advances in the management of impotence.

With an estimated ten to twenty million men in the United States suffering from impotence, major advances have been made relative to the understanding of the pathophysiology of this disease. These advances have been translated into improved treatment options. Several exciting novel pharmacotherapeutic agents are in the final phase of their clinical trials. These should provide more favorable prospects for men with sexual dysfunction.
