The diminishing role of transurethral resection of the prostate.

ABSTRACT

BACKGROUND: This study provides an update of patterns in transurethral resection of the prostate (TURP) rates in the United States and the extent of TURP-detected prostate cancer incidence rates. METHODS: Analyses are based on data from the National Hospital Discharge Survey, the Surveillance, Epidemiology, and End Results Program, and the U.S. Census Bureau for the years 1996 through 2006. RESULTS: TURP procedure rates were 6, 14, and 18 times greater in men aged 60 to 69, 70 to 79, and >or=80 years compared with men aged 50 to 59, respectively. During 1996-2006, the estimated annual percentage change in TURP rates was -10.5 (95% confidence interval [95% CI] -14.1 to -6.7) for ages 50 to 59, -7.4 (95% CI -9.2 to -5.6) for ages 60 to 69, -6.2 (95% CI -7.6 to -4.8) for ages 70 to 79, and -7.7 (95% CI -9.5 to -5.8) for ages >or=80 years. TURP-detected prostate cancer incidence rates were 2, 7, and 17 times greater in men aged 60 to 69, 70 to 79, and >or=80 years compared with men aged 50 to 59, respectively. The estimated annual percentage change in trend was -17.8 (-20.6, -15.0) for ages 50 to 59, -14.8 (-16.6, -13.0) for ages 60 to 69, -10.8 (-12.0, -9.7) for ages 70 to 79, and -8.2 (-10.0, -6.5) for ages >or=80 years. Trends in prostate cancer incidence rates peaked in 2002 and decreased thereafter. Some of the decreasing trend in rates among older age groups is because of a decrease in TURPs and consequently a decrease in incidental TURP-detected cases. CONCLUSIONS: TURP procedure rates and incidental TURP-detected prostate cancer incidence rates have declined and will likely continue to decline in the future.
