Recent Trends in Transurethral Surgeries and Urological Outpatient Procedures: a Nationwide Populationbased Cohort Study

ABSTRACT

Background@#Demographic change and advances in technology affect transurethral surgery and outpatient procedures in the urologic field. There are few population-based studies that accurately assess the trend of transurethral surgery and outpatient procedures including diagnostic tests. We investigated the recent epidemiologic trends in transurethral surgeries and urological outpatient procedures from 2009 to 2016 in Korea using the entire populationbased cohort. @*Methods@#We analyzed medical service claim data of transurethral surgery, urological outpatient procedures submitted by medical service providers from the Health Insurance Review and Assessment Service from 2009 to 2016. @*Results@#Transurethral ureter surgery increased by 134.9% from 14,635 in 2009 to 34,382 in 2016 (B = 2,698; R 2 = 0.98; P 2 = 0.97; P 2 = 0.04; P = 0.617) and urethral surgery (B = −12; R 2 = 0.18; P = 0.289). The significantly increasing trends in cystoscopy (B = 5,260; R 2 = 0.95; P 2 = 0.99; P 2 = 0.77; P = 0.003) and electrical stimulation treatment (EST B = −1,034; R 2= 0.87; P < 0.001) significantly decreased. @*Conclusion@#In Korea, transurethral ureter surgery and transurethral bladder surgery have been continuously increasing. Transurethral prostate surgery and transurethral urethral surgery remained constant with no increase or decrease. Cystoscopy and uroflowmetry continue to increase, while UDS and EST continue to decrease.
