    Notes: Abstract Sonoenorphotogic criteria of male urethral external sphincter under normal and pathologic conditions were evaluated by direct visualization with endoluminal US and correlated with normal anatomy. Between October 1992 and August 1993 18 patients were examined prospectively. We used a 12.5 MHz interventional US machine eduipped with a Sonicat 9-French catheter system. In all cases the anatomic structure of the external male urethral sphincter was visualized and demonstrated not in the expected circular configuration, but rather in an “omega sign” of the muscle and fibers, functioning with retraction of the ventral and lateral parts of the muscle, surrounding the urethra. Disorders of muscular function were revealed in 8 cases, and 6 cases demonstrated scarring and thinning of the muscle. Endoluminal-US offers the possibility of direct visualization not only of the male external sphincter, but also of the contracting mechanism in cross-sectional view. An exact description of sonoanatorny and the pathoenorphologic correlation is more accurate. The method therefore has the benefit of better access to further therapeutic considerations.

    Notes: Abstract. The aim of this pilot study in 54 patients was to improve the visualization of the anatomy and postoperative changes in the pelvic topography after bilateral ureteroileal urethrostomy, using surface rendering of electron beam CT (EBCT) data for the 3D display. Fifty-four patients (39 men and 15 women) were scanned with an EBCT unit between 3 and 110 months after performing orthotopic ureteroileal urethrostomy (“Hemi-Kock”) or ureteroileal rectosigmoidostomy. Various parameters and spatial viewing points were used in the 3D reconstruction, which was performed interactively on external workstations with commercially available software. The anti-reflux nipple was visualized as a distinct structure in all patients. In 8 patients with an interval of more than 12 months between surgery and CT, the pouch had developed an ovoid shape almost indistinguishable from the original bladder. The segmented data sets were partly animated to display the anatomy as virtual endoscopy. Three-dimensional depiction and virtual endoscopy of the neobladder using EBCT are a new way of imaging the postoperative anatomy. Its clinical efficacy in the diagnosis of inconclusive postoperative morbidity, especially voiding problems, and planning of necessary therapy have to be the subject of further evaluation.
