Reoperation Rates and Mortality After Transurethral and Open Prostatectomy in a Long-term Nationwide Analysis: Have We Improved Over a Decade?

OBJECTIVE: To assess long-term reoperation rates and mortality after transurethral resection of the prostate (TURP) and open prostatectomy (PE) as therapy for lower urinary tract symptoms due to benign prostatic enlargement.

METHODS: The present study analyzes a nationwide database of all patients who underwent TURP/open PE during 2002-2006 and who were followed up for 8 years. Actuarial cumulative incidences of reoperation (TURP, urethrotomy, bladder neck incision) and death were calculated. Data were provided by the Austrian Public Health Institute. This series was compared with a previously published almost equally sized nationwide cohort that underwent surgery during 1992-1996 in Austria.

RESULTS: Between 2002 and 2006, a total of 21,674 patients underwent TURP (n = 20,388) or open PE (n = 1,286). At 8 years, the re-TURP rate after primary TURP was 8.3% vs 4.3% after open PE. The re-TURP rate was higher in the 80+ cohort. The overall endourological reintervention rate at 8 years was 12.7% for TURP and 8.8% for open PE. Reintervention rates did not improve compared with the 1992-1996 series. The 30-day in-hospital mortality rate was 0.1% for TURP and 0.2% for open PE. Mortality rates improved by approximately 20% compared with the 1992-1996 series.

CONCLUSION: In Austria, TURP rates remained stable between 1992 and 2006, paralleled by a 50% decline of open PE. Within a decade, mortality rates declined by 20%, yet reintervention rates remained unchanged.
