Prospective analysis of the incidence of ipsilateral adrenal metastasis in localized renal cell carcinoma.

Purpose: The incidence of ipsilateral adrenal metastasis in renal cell carcinoma was evaluated in a prospective fashion to understand more fully the natural history of this disease.

Materials And Methods: During a 15-month period 128 radical nephrectomies were performed for stages T1 to T3bN0M0 renal cell carcinoma at our institution. Of these specimens 100 adrenal glands were of sufficient integrity to allow for thin sectioning.

Efficacy of a new endoureterotomy balloon for the treatment of benign ureteral strictures using the porcine model.

Objectives: Endoureterotomy and balloon dilation are techniques that have shown promise as treatment modalities for benign ureteral stricture disease. In this animal investigation, the results of a new endoureterotomy balloon that simultaneously incises and dilates the ureteral stricture via a retrograde approach are discussed.

Methods: Using the female pig model, 9 subjects with benign ureteral strictures were treated: 7 with the endoureterotomy balloon and 2 with balloon dilation only.

Prostatic stents. Current perspectives for the management of benign prostatic hyperplasia.

The urethral stent is a relatively new treatment modality for symptomatic BPH. Our knowledge and experience using various stenting devices for this indication have been enhanced considerably within the last 12 to 18 months as the results from more investigations have become available. These preliminary data indicate that the intraurethral stent is an effective and safe treatment for symptomatic BPH in properly selected patients.

Percutaneous antegrade endopyelotomy: review of 50 consecutive cases.

Between 1988 and 1993, 50 percutaneous antegrade endopyelotomies were performed for ureteropelvic junction obstruction at this institution. The success of the procedure was based on radiological parameters as well as patient symptomatology. The overall success rate of the procedure was 88%.

Prospective analysis of multifocality in renal cell carcinoma: influence of histological pattern, grade, number, size, volume and deoxyribonucleic acid ploidy.

In an effort to characterize more fully multifocal renal cell carcinoma, 100 radical nephrectomy specimens with localized renal cell carcinoma were analyzed in a prospective fashion. Analysis of each specimen consisted of preoperative computerized tomography or magnetic resonance imaging, standard pathological examination with frozen section and 3 mm. step sectioning under magnification.
