General anesthesia and contrast-enhanced computed tomography to optimize renal percutaneous radiofrequency ablation: multi-institutional intermediate-term results.

Introduction: Percutaneous renal ablation is often performed under conscious sedation and without contrast-enhanced imaging. We evaluated intermediate-term outcomes of patients undergoing percutaneous contrast-enhanced computed tomography (CT)-guided radiofrequency ablation (RFA) under general anesthesia (GA) at two high-volume centers.

Materials And Methods: Prospectively maintained Institutional Regulatory Board-approved databases were searched to identify patients treated with percutaneous RFA using contrast-enhanced CT under GA.

Renal thermal ablative therapy.

Energy targeting is greatly enhanced through imaging modalities, which greatly assist needle placement or energy delivery to the optimal location for maximal effectiveness. When vital structures obscure access to the renal lesion, laparoscopic mobilization of these structures with direct visualization of the tumor can increase the likelihood of ablation success and minimize complication risk. Ablative therapies are attractive because of their minimal impact on patient quality of life in addition to their morbidity and cost.

Central and deep renal tumors can be effectively ablated: radiofrequency ablation outcomes with fiberoptic peripheral temperature monitoring.

Background And Purpose: The "overtreatment" of incidental renal lesions with nephrectomy and a desire to reduce patient morbidity and preserve renal function resulted in the development of nephron-sparing surgical alternatives. As clinical experience accumulates with radiofrequency ablation (RFA), confidence in the oncologic effectiveness of the management method increases. Although many investigators describe RFA management success in small-to medium-sized renal tumors, hesitation is expressed when managing endophytic, central, or hilar lesions.

Partial segmental thrombosis of corpus cavernosum: case report and review of world literature.

Partial segmental priapism is an unusual clinical condition characterized by thrombosis within the proximal corpora cavernosa. Previous management strategies have included open exploration, surgical shunts, corporal injection, irrigation, and oral medication therapy. We report a case of a 37-year-old man treated conservatively with full restoration of erectile function.
