Epidemiologic Survey of Lower Urinary Tract Symptoms in Asia and Australia Using the International Prostate Symptom Score

Background The prevalence of lower urinary tract symptoms was determined by survey as an initial step in estimating the significance of benign prostatic hyperplasia (BPH) in Asia and Australia.

ESTIMATE CRITERIA FOR EFFICACY OF TREATMENT IN BENIGN PROSTATIC HYPERPLASIA

Background: Various treatment modalities for benign prostatic hyperplasia (BPH) have emerged and are now in use or await evaluation of clinical usefulness. It is difficult, however, to compare their efficacies on a single scale, because standardized criteria for therapeutic efficacy of BPH treatments have not been established.

Estimate Criteria for Diagnosis and Severity in Benign Prostatic Hyperplasia

Background: Standard severity criteria for benign prostatic hyperplasia (BPH) are needed to facilitate clinical and epidemiologic investigations in the common terminology.

TREATMENT OF BENIGN PROSTATIC HYPERPLASIA WITH HIGH INTENSITY FOCUSED ULTRASOUND: AN INITIAL CLINICAL TRIAL IN JAPAN WITH MAGNETIC RESONANCE IMAGING OF THE TREATED AREA

Background

THE THREE‐CIRCLE SINGLE J CATHETER A MORE STABLE URETHRAL CATHETER FOR PRESSURE FLOW STUDIES

We describe a single J urethral catheter which has been specially designed to facilitate stabilization during voiding in pressure flow studies. It has a tip with three circles, which prevents the catheter from slipping out even when there is a sudden increase in intra‐abdominal pressure.
