Validation of the modified American Urological Association symptom score.

Purpose: We created a shorter version of the American Urological Association symptom score, called UWIN (urgency, weak stream, incomplete emptying and nocturia).

Materials And Methods: Participants in Prostate Cancer Awareness Week from 2006 and 2007 were administered the regular American Urological Association symptom score and UWIN. A total of 278 participants completed each questionnaire.

Methods of developing UWIN, the modified American Urological Association symptom score.

Purpose: The American Urological Association symptom score instrument is widely used to assess lower urinary tract symptom severity in men. We describe the methods used to develop a shorter form of the American Urological Association symptom score that may provide symptom score assessment with minimal compromise in accuracy.

Materials And Methods: Complete American Urological Association symptom score data were collected on 8,731 men who attended Prostate Cancer Awareness Week in 2003 or 2004.

High-intensity focused ultrasound: ready for primetime.

Prostate cancer (CaP) is the second most common cause of cancer deaths in the United States and the incidence of CaP has remained constant at 165 cases per 100,000 men. Since 1990, the age-adjusted death rate has decreased by 31%. In this article, the authors review the current literature on the experimental therapy for HIFU.

Targeted focal therapy for prostate cancer: a review of the literature.

Improvements in prostate cancer diagnosis and treatment have resulted in a decreasing age-adjusted death rate. But improved diagnostic tools have not delivered a proportionate decrease in mortality, primarily because physicians now are diagnosing - and treating - more clinically insignificant tumors. Targeted focal therapy (TFT) uses three dimensional (3D) mapping biopsies to guide cryotherapy so that it targets lesions themselves while sparing surrounding healthy tissues, thereby avoiding side effects associated with more invasive treatments.

Targeted focal therapy for prostate cancer: a review.

Purpose Of Review: Prostate cancer screening has shifted the diagnosis of prostate cancer to lower grade, organ confined disease. Radical prostatectomy or radiation therapy has been shown to be overtreatment in 30% of patients. In this review, we will discuss targeted focal therapy (TFT) using the modalities of cryotherapy or high intensity focused ultrasound as an alternate treatment for low-risk prostate cancers.

Real-time 3D laparoscopic ultrasonography.

We have previously described 2D array ultrasound transducers operating up to 10 MHz for applications including real time 3D transthoracic imaging, real time volumetric intracardiac echocardiography (ICE), real time 3D intravascular ultrasound (IVUS) imaging, and real time 3D transesophageal echocardiography (TEE). We have recently built a pair of 2D array transducers for real time 3D laparoscopic ultrasonography (3D LUS). These transducers are intended to be placed down a trocar during minimally invasive surgery.
