[Complications of radical retropubic prostatectomies based on the Martin criteria].

BACKGROUND: In 2002 the ten Martin criteria were proposed which should be met when reporting complications following surgery. Only a few studies have evaluated complication rates after open retropubic radical prostatectomy using these criteria. In this study we report on complications of open retropubic radical prostatectomy using the standardized Clavien-Dindo reporting methodology. PATIENTS AND METHODS: The overall complication rate was 28.6% (907 of 3,172). We registered 1,069 medical or surgical complications in 907 patients. Of these, 714 complications were grade I (66.8%), 195 grade II (18.2%), 139 grade III (13%), and 17 grade IV (1.6%), respectively. The mortality rate (grade V) was 0.1% (4 of 3,172). Older age (hazard ratio 1.049, p=0.023) and a performed lymphadenectomy (hazard ratio 1.804, p=0.024) were independent predictors for high-grade complications (grade III or greater) on multivariate analysis.
RESULTS: Between 08/2003 and 06/2010 complications of 3172 consecutive men who underwent open retropubic radical prostatectomy at a single center were recorded prospectively. Complications which occurred within a period of 30 days postoperatively were graded retrospectively according to the Clavien-Dindo classification. Clinical and histopathological risk factors were statistically evaluated for an association with complication grades. All 10 Martin criteria were fulfilled.
CONCLUSIONS: Using the Clavien-Dindo classification as a standardized reporting methodology, we observed an acceptable overall complication rate of 28.6%. In the majority (85% of all complications) lower grade complications occurred. In this series older age and a lymphadenectomy were risk factors for high-grade complications (III-V). A patient's age remains an important factor when considering the indication for radical prostatectomy.
