Existing population-based reports on complication rates after minimally invasive radical prostatectomy (MIRP) did not address temporal trends.
To examine contemporary temporal trends in perioperative MIRP outcomes.
Design, setting, and participants
Between 2001 and 2007, 4387 patients undergoing MIRP were identified using the Nationwide Inpatient Sample.
To examine the rates and trends of intraoperative and postoperative complications, transfusion rates, length of stay in excess of the median, and in-hospital mortality. We tested the effect of the late (2006–2007) versus the early (2001–2005) study period on all outcomes using multivariable logistic regression models controlled for clustering among hospitals.
Results and limitations
Intraoperative and postoperative complications decreased from 7.0% to 0.8% (p
Our analyses demonstrate that in-hospital complication rates and length of stay after MIRP decreased over time. This implies that temporal differences specific to complication rates after MIRP must be considered when comparisons are made with other radical prostatectomy techniques.
