INTRODUCTION AND OBJECTIVES 

Studies from tertiary care center suggests, that minimal invasive radical prostatectomy (MIRP) may be associated with a more favorable rate of complication, shorter length of stay (LOS) and possibly equal cost relative to open radical prostatectomy (ORP). We assessed these three endpoints in a large population-based cohort.

METHODS 

In the State of Florida, 2105 MIRP and 24071 ORP were performed between January 1st, 2002 and December 31th 2008. The rates of complications (all categories grouped as any type of complications, as well as specific individual complications) and the distribution of costs and LOS were compared between the two groups (MIRP vs. ORP).

RESULTS 

The number of overall complication (5.6% vs. 7%; p=0.008), digestive complications (3.2% vs. 4.3%; p<0.012) and the transfusion rate (1.8% vs. 10.3%; p<0.001) statistical significantly differed between MIRP and ORP. After MIRP, mean LOS was shorter than after ORP (1.9 vs. 2.7 days; p< 0.001). The total hospital charges were higher for MIRP vs. ORP (36.219 vs. 31.809; p<0.001) (MIP range: 2,259-324,048 dollars vs. RP range: 1,580-626,178 dollars). After adjustment for the baseline patients' characteristics like age, CCI, hospital and surgical volume, year and type of surgery, no statistically significant differences for the complication rates between the two procedures were found (p=0.265). In the linear regression model, a statistical significant relationship for the total hospital charges were found for lower surgical and lower hospital volume, year of surgery and patients CCI (each p<0.001), but not for type of surgery. The LOS was influenced by age, CCI, hospital and surgical volume, year and type of surgery (each p<0.001).

CONCLUSIONS 

Complication rates and total hospital charges in MIRP patients were not statistically significantly different from ORP patients. After adjustment for baseline patients' characteristics, differences between both cohorts exist for the length of hospital stay.
