- Abstract
Study Type – Therapy (case series) Level of Evidence 4 OBJECTIVE To determine the mechanism for delayed healing of the urinary anastomosis after radical retropubic prostatectomy (RRP). PATIENTS AND METHODS The volumes of the para-anastomotic haematoma (PHV) and anastomotic extravasation were measured by ultrasonography in 95 men after RRP. The performance characteristics of PHV for predicting urinary extravasation were ascertained and compared with that of postoperative blood loss, measured as the difference between the haematocrit immediately after RRP and that at discharge. RESULTS The sensitivity and specificity of PHV for predicting urinary extravasation at a threshold of 37 mL was 100% and 96%, respectively. PHV was superior to postoperative blood loss in predicting anastomotic extravasation, as shown by an area under the receiver operating curve of 0.99 vs 0.91, respectively. CONCLUSIONS Our findings provide compelling evidence that delayed healing of the anastomosis after RRP is due to distraction forces secondary to a pelvic haematoma. The accuracy of PHV as a predictor of anastomotic extravasation suggests that this measurement might replace cystography for assessing anastomotic integrity after RRP.
