Diagnosis of male posterior urethral stricture: comparison of 64-MDCT urethrography vs. standard urethrography.
Summary of "Diagnosis of male posterior urethral stricture: comparison of 64-MDCT urethrography vs. standard urethrography."
There are no reports regarding voiding/retrograde urethrography with 64-row multidetector CT (64-MDCT).To compare the clinical relevance of conventional voiding/retrograde urethrography and 64-MDCT urethrography for the evaluation of male posterior urethral stricture.
From January to October 2009, 21 men were referred to our institution for the management of posterior urethral stricture. The patients were evaluated with conventional voiding and retrograde urethrography and 64-MDCT urethrography. The patients were examined by open operative intervention which was required in all patients. The radiologic data were compared using the operative findings.
64 MDCT urethrography provided extra clinical data in ten patients. It was superior to conventional urethrography for judging the urethral stricture length in three patients, characterizing the site of urethra-rectal fistula in four patients, and accurately delineating the proximal urethra in six patients.
64-MDCT urethrography is a promising tool as an alternative to traditional radiographic methods for defining male urethral strictures. It has the advantage of examining patients only in one position, without distortion, and by generating three-dimensional images; it can accurately measure the stricture length, aid in the diagnosis of some associated pathological conditions, such as urethrorectal fistula, and does not expose the physician to radiation.

Narrowing of any part of the URETHRA. It is characterized by decreased urinary stream and often other obstructive voiding symptoms.
A birth defect due to malformation of the URETHRA in which the urethral opening is below its normal location. In the male, the malformed urethra generally opens on the ventral surface of the PENIS or on the PERINEUM. In the female, the malformed urethral opening is in the VAGINA.
A birth defect due to malformation of the URETHRA in which the urethral opening is above its normal location. In the male, the malformed urethra generally opens on the top or the side of the PENIS, but the urethra can also be open the entire length of the penis. In the female, the malformed urethral opening is often between the CLITORIS and the labia, or in the ABDOMEN.
Comparison of various psychological, sociological, or cultural factors in order to assess the similarities or diversities occurring in two or more different cultures or societies.
