title: [Predictors of operative blood loss in patients undergoing small incision radical prostatectomy].
abstract: We performed 82 cases of small incision radical prostatectomy from July, 2003 to September, 2009. There were 38 cases of cT1c, 41 cases of cT2, and 3 cases of cT3. Mean operative time was 222 +/- 31.7 (min.). Mean operative blood loss was 1,232 +/- 583 (ml). We evaluated factors predicting operative blood loss, such as prostate volume, body mass index (BMI), age, and preoperative PSA level. Group with smaller prostate volume and group with lower BMI showed significantly less blood loss compared to that of a higher group (p = 0.0009, p = 0.0014, respectively). Multivariate analysis showed that prostate volume and BMI were significant predictors for operative blood loss (p = 0.0005, p = 0.0122, respectively). Prostate volume and BMI may be a useful predictor for operative blood loss.
