The present study describes a perfected device for retrograde urethrography (RUG). The device allows RUG to be performed using a balloonless catheter and with assessment of the various problems of the urethra. The procedure is simple and well tolerated by patients and represents an interesting alternative to the conventional RUG technique.

BACKGROUND In spite of the advanced imaging methods, MRI and CT-Scan, the role of ultrasonography is still unique in some fields of genitourinary tract diseases. AIM This study was aimed at assessing this role in the evaluation of male urinary stricture, and comparison with standard retrograde urethrography (SUG). METHODS This was a cross-sectional study. The patients include those who were...

A special class of braids, called woven, is introduced and it is shown qcxthat every conjugation class of the braid group contains woven braids. In consequence tame links can be presented as plats and closures of woven braids. Restricting on knots we get the ‘woven version’ of the well-known theorem of Markov, giving moves that are capable of producing all woven braids with equivalent closures....

We propose a contour operator, called CORF, inspired by the properties of simple cells in visual cortex. It combines, by a weighted geometric mean, the blurred responses of difference-of-Gaussian operators that model cells in the lateral geniculate nucleus (LGN). An operator that has gained particular popularity as a computational model of a simple cell is based on a family of Gabor Functions (...

The aim of the present study is to describe and evaluate a new technique for performing Computed-Tomography Retrograde Urethrography (CT-RUG). Males with urethral anomalies detected by retrograde urethrography (RUG) and/or sonourethrography (RSUG) underwent CT-RUG using clamp method three radiologists evaluated in each separately blindly. was done successfully all cases (n = 22), means 6 min du...

The Woven Stories is a tool for writing stories collaboratively. In order to represent the written stories adaptively, we need to construct description about the content of the stories and the relative information between di erent stories. The formal presentation of Woven Stories is called StoryML and it can be used for adaptive content representation of the stories.
