OBJECTIVE To determine whether prostate-specific antigen (PSA)-based screening alters the proportion of organ-confined prostate cancers detected. DESIGN A prospective, nonrandomized, serial PSA-based screening trial (follow-up from 6 to 37 months), and a concurrent comparison group. SETTING General community outpatient screening program based at a(More)
It is known that bone mineral density (BMD) is low in men who are hypogonadal. However, the rate and sites of bone loss following testosterone deficiency are not known. The resulting hypogonadism after GnRH analog therapy for the treatment of prostate cancer allows us to examine bone loss and bone resorption immediately after testosterone withdrawal.(More)
We evaluated recovery of erections and urinary continence following anatomical radical retropubic prostatectomy in a series of 784 consecutive patients with clinical stage A or B prostate cancer. Nerve sparing radical prostatectomy was performed in men deemed appropriate candidates. Recovery of erections sufficient for intercourse and urinary continence(More)
PURPOSE We determined the biological variation of the total, free and percent free serum prostate specific antigen (PSA) in men 50 years old or older. MATERIALS AND METHODS Between July 1995 and February 1996 we studied 84 healthy men from our PSA screening study to determine biological variation by calculating the coefficients of variation of 3 PSA(More)
A total of 6 pregnant women with obstructing urinary calculi was managed by percutaneous nephrostomy drainage placed under ultrasound guidance with the patient under local anesthesia. All patients initially had relief of acute obstruction. However, occlusion of the percutaneous nephrostomy tubes with debris necessitated tube changes in 5 of 6 patients. In 2(More)
The percutaneous nephrostomy tract has provided urologists with antegrade access to the upper urinary tract. Via this approach ureteropelvic junction obstruction has been treated with an endoscopically controlled incision with a cold knife. While less invasive than an open operation, we have noted significant discomfort from the 24 to 32F percutaneous(More)
OBJECTIVES To determine the prevalence of osteopenia and osteoporosis by central (spine and hip) and peripheral (radius) bone mineral density (BMD) in men with prostate cancer undergoing androgen-deprivation therapy (ADT). Low BMD and fractures are prevalent in this group of men. Most published studies on ADT-related bone loss have documented the loss of(More)
We are investigating the role of the early response transcription factor, nerve growth factor inducible A gene (NGFI-A), as a modulator of retinoblastoma (RB) gene transcription in prostate cells. Examination of the RB promoter reveals a novel element GCGGGGGAG located at nucleotides 152-144 upstream of the methionine initiation codon. This sequence shares(More)
