INTRODUCTIONGuidelines for the use of urodynamics have undergone a significant narrowing of scope in recent years, particularly as they pertain to the use of urodynamics for stress incontinence in women. Whether these changes have affected the use of urodynamics in practice is unknown. The goal of this study is to quantify the percentage of urologists who are performing urodynamics, to determine how trends have changed during the time studied and to better understand why these studies are being performed by identifying the associated diagnosis codes. METHODSWe queried the 6-month procedure logs submitted by applicants for part II ABU (American Board of Urology) certification or recertification between 2003 and 2014. The number of procedures with urodynamics CPT codes were abstracted (51725, 51726, 51772, 51784, 51785, 51792, 51795, 5179, 51797) along with the certification year, patient gender and ICD-9 diagnosis used for each procedure. RESULTSDuring the 11-year period of data 7,849 practice logs were submitted to the ABU. Overall 91% of certifying applicants and 89.5% of recertifying applicants performed urodynamics. This number increased from 82.6% of certifying urologists and 70.3% of recertifying urologists in 2003 to 94.7% of recertifying urologists and 93.7% of certifying urologists in 2014. In 2003, on average, each certifying applicant performed 99 urodynamics procedures. This number increased to 149 procedures per applicant in 2014, for a 49.8% increase overall from the start of the study period. For recertification candidates an average of 125 procedures was performed per candidate in 2003. The average increased to 187 procedures per candidate in 2014 for a 49.5% increase in procedures performed. Videourodynamics were performed by 8.1% of certification or recertification applicants overall. This increased from 1% of recertification applicants and 1.8% of certification applicants in 2003 to 6% and 12.5% of recertification and certification applicants, respectively, in 2013. The ICD-9 codes most frequently associated with pressure flow studies were 625.6 (stress urinary incontinence-female) and 788.41 (urinary frequency). The ICD-9 code most commonly associated with videourodynamics across our study was 625.6 (stress urinary incontinence-female). CONCLUSIONSSince 2003 the percentage of applicants for ABU certification or recertification using urodynamics in their practice has increased from 76.5% to 94.2%. There has also been a 49.7% increase in the number of urodynamics procedures performed per candidate during that period, indicating an overall increase in the use of urodynamic studies.
