A perfected device for performing retrograde urethrography

Abstract

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.

Keywords: device; retrograde urethrography; urethra; urethral stricture.

Illustration of the device coupled to a catheter. A) Catheter guide: the guide has two channels to fit 6- and 10-Fr catheters. B) Padded ring: the perforated tip of the catheter must be pushed beyond the ring (double-headed arrow) so that the contrast material can flow unobstructed after external compression. C) Base: incorporates a V-notch (arrowhead) to enable the band to be cut for decompression. D) Adjustable band: the band is tractioned to achieve external compression.
