11C-Acetate PET imaging for renal cell carcinoma.

Purpose: In this study, we investigated the effectiveness of positron emission tomography (PET) with (11)C-acetate (AC) for evaluation of renal cell carcinoma.

Methods: Enrolled in the study were 20 patients with suspected renal tumour, one of whom had three renal lesions. In all, 22 renal lesions were evaluated.

Association between lower urinary tract symptoms and serum levels of sex hormones in men.

Objectives: Despite the well-known association between lower urinary tract symptoms (LUTS) and male sexual dysfunction, few data are available that describe the relationship between LUTS and sex hormones. The aim of this study was to investigate a possible association between the severity of LUTS and the serum levels of sex hormones in men.

Methods: A total of 182 randomly selected men attending our general urology clinic were recruited.

Correlation between the Aging Males' Symptoms Scale and sex steroids, gonadotropins, dehydroepiandrosterone sulfate, and growth hormone levels in ambulatory men.

Introduction: Partial androgen deficiency of the aging male (PADAM) is defined as a biochemical syndrome associated with advancing age that is characterized by a deficiency in serum androgen levels. The Aging Males' Symptoms (AMS) Scale was developed to evaluate PADAM-related symptoms and is currently used worldwide; however, it has been reported that PADAM-related symptoms evaluated by this scale are not related to serum testosterone levels. In addition to testosterone, the levels of other hormones also decrease with age; therefore, multihormone alterations may influence PADAM-related symptoms.
