Urodynamics in women with stress and urge incontinence.

Subtracted bladder pressure recording is the ideal method to diagnose bladder instability in supine and erect positions. Uroflowmetry demonstrated higher peak flow rates in our stable bladder group. Lateral cystourethrography showed a higher degree of urethral hypermobility in the same group. We believe that cystometry with subtraction is still the cornerstone in the evaluation of these patients. Uroflowmetry and lateral cystography may add some information and deserve further investigation in a large number of patients. Intravesical pressure alone, external urethral sphincter electromyography, and static urethral pressure profilometry were of no value in the evaluation of our patients.

Use of exteriorized stents in vasovasostomy.

Ten patients, three to fifteen years postvasectomy, underwent vasovasostomy. Using 2-0 nylon, stents were brought to the scrotal surface. Vas anastomosis was accomplished with a single transmural layer of 6-0 or 7-0 proline or chromic sutures under loupe magnification. Stents were removed in seven to ten days. After two years, a pregnancy rate of 70% was achieved, comparing favorably with other more difficult operative techniques.

Leiomyosarcoma of prostate gland.

A case of leiomyosarcoma of the prostate is presented. The patient was successfully treated with transperineal radon seed implantation and external irradiation. The five-year, disease-free survival suggests that such patients can benefit from this therapeutic approach.

Evaluation and treatment of priapism.

We herein review the last 29 patients with priapism treated at our hospitals with respect to the physiology and pathophysiology of erection and priapism, respectively, and present a rational approach to the management of priapism. Emphasis is given to the corpus cavernosum to corpus spongiosum shunt with a vascular anastomosis technique.

Investigation of different combinations of estrogen therapy and radiation therapy on prostatic adenocarcinoma (R-3327).

The relative effectiveness of different combinations of estrogen therapy and radiation therapy against the R-3327 prostatic adenocarcinoma of the Copenhagen rat was studied. Because of similar actions of estrogens and radiation in the cell cycle, and possibly antagonistic effects reported in the clinical literature, we looked for an antagonism between these two therapeutic modalities. Radiation therapy consistently showed a greater tumor inhibitory effect than estrogen therapy alone at the dose tested. Combinations of radiation therapy with hormonal manipulation did not appear to show a greater inhibition of tumor growth than radiation therapy alone. There also did not appear to be an antagonistic effect between these two modalities in this system.
