abstract
Transperineal sonocystography was equivalent to FC in detecting anastomotic leaks after RP. It provides a safe, inexpensive, and effective alternative to traditional FC for evaluating the integrity of the vesicourethral anastomosis after RP.
reason, objective, purpose
Fluorocystography (FC) is the reference standard for assessing the integrity of the vesicourethral anastomosis after radical prostatectomy (RP). We describe a new technique, transperineal sonocystography (TPSC), as a cost-effective alternative and more informative than FC.
materials used
Between May 1, 2007, and October 1, 2008, 175 consecutive men underwent open or robotically assisted RP. Before Foley catheter removal, all men underwent both TPSC and FC, which were performed and interpreted by a single radiologist. Transperineal sonocystography was performed first with real-time imaging after gravity filling of the bladder with 150 mL of normal saline. Extravasation of saline was calculated by computer software after outlining the observed pooling of extravasated saline in the transverse and longitudinal views. Fluorocystography was performed after TPSC using our standard protocol, with qualitative classification of anastomotic leaks as none, slight, moderate, or severe. RESULTS: The mean extravasation volume +/- SEM was 16.3 +/- 2.9 mL. Of the 175 patients, 142 (81.2%) showed no anastomotic leaks on TPSC. Of the remaining 33 patients (18.8%), TPSC identified 20 (11.4%), 13 (7.4%), and 0 patients with slight, moderate, and severe leaks, respectively. Excellent concordance was shown between TPSC and FC.
