PURPOSE: To evaluate reliability of Trans-rectal ultra-sonography (TRUS) guidance with @entity4831 injection for prostate localization before radiotherapy planning. MATERIAL AND METHODS: From October 1997 to March 2000, 31 @entity1 with @entity263 and six @entity1 with anastomotic recurrence after radical prostatectomy had TRUS-guided injection of @entity4831 . Two milliliters of @entity4831 were injected into each side of the prostate and 1 ml into both seminal vesicles with a 22 Gauge CHIBA needle and US probe guide before radiotherapy planning. We had established a contrast quality index (0 for no prostate enhancement to 5 for efficient pacification without any diffusion). On simulation films, we had performed anatomic measurements for comparison with other anatomic studies. RESULTS: For all 37 @entity1 , TRUS-guided injection was well tolerated. Among 31 @entity1 with the prostate in situ, three had no apex opacification and 15 had no vesicle enhancement or peri-vesicle space diffusion. However, in 19 @entity1 there was good contrast quality with an index score of > or =3. The majority of @entity1 had prostatic apex between 1.5 and 3.5 cm from ischial tuberosities ligne (27 from 28 evaluable for apex). Among 19 evaluable @entity1 , 15 had seminal vesicles 2-4 cm above the top of pubis. For six @entity1 with anastomotic recurrence after radical prostatectomy, @entity4831 was precious aid to locate it. We had only one failure because of a precocious bladder absorption relating to a delay which is too long between rectal probe locating and portal films. CONCLUSION: TRUS injection of @entity4831 is a simple, inexpensive, relatively safe technique for localization of prostatic apex, but not appropriate for seminal vesicles enhancement. This is also an interesting method to locate anastomotic recurrence.
