NCT01790776 · Status: WITHDRAWN · Phase: PHASE3 · Type: INTERVENTIONAL

No results posted yet for this study

Summary

Conventional urethrography is the standard diagnostic evaluation for patients with a suspicion of urethral stricture. The radiation dose of this examination is 5-9 mSV. Sono-urethrography was introduced in 1988 (McAninch et al. , J Urol 1988); the diagnostic accuracy of sono-urethrography is equal compared to conventional urethrography, with even a better measurement of stricture length and degree of spongiofibrosis with sono-urethrography. However, sono-urethrography remained underused among urologists and radiologists.

Patients will be randomly assigned into two groups:

Group A: conventional urethrography Group B: sono-urethrography In case sono-urethrography is inconclusive or of poor quality, a conventional urethrography will be performed.

The radiation dose in the two groups will be measured. The stricture length and location will be recorded and compared with the perioperative findings in order to evaluate the diagnostic accuracy. The complications of the procedure(s) will be recorded with a questionnaire directly after and two weeks after the conventional or sono-urethrography.

Conditions

  • Urethral Stricture Disease

Interventions

RADIATION

Urografin 30%

Urografin 30% (Natrium amidotrizoas 10G, Megalumin, Amidotrizoas 65G, Natrii calcii edetas, water for injection 250 ml, with 146 mg iodium/ml). The tip of a bladder catheter is placed at the external urethral meatus and fixed at this location. The solution (urografin 30 %) is instilled.

RADIATION

NaCl 0,9 % in aqua

The tip of a bladder catheter is placed at the external urethral meatus and fixed at this location. The solution (NaCl 0,9 % in aqua) is instilled. If the result is inconclusive, urografin 30 % will be instilled.
