Accuracy of prostate volume measurements using transrectal multiplanar three-dimensional sonography.

The aim of this study is to evaluate the accuracy of three-dimensional (3D) ultrasound in comparison with conventional bidimensional (2D) sonography in prostatic calculations. The study was performed using a Kretztechnik Voluson 530D machine with a 7.5 MHz endocavitary transducer.

Hypospadias: incidence and effects on psychosexual development as evaluated with the Minnesota Multiphasic Personality Inventory test in a sample of 11,649 young Italian men.

Purpose: We evaluated the incidence of hypospadias and its effects on psychosexual development in a sample of 11,649 young Italian males. Over the last 30 years only about 30 major publications have addressed these issues and the results of many studies have been contrasting. Some defects in methodology, such as low response rates, heterogeneity of age ranges and the choice of controls, have been the main limitations.
