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 population-based 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 < 0.001). The transurethral bladder surgery increased by 65.5% from 12,482 in 2009 to 20,658 in 2016 (B = 1,149; R 2 = 0.97; P < 0.001). Over the 8-years period, there were not significant changes in transurethral prostate (B = 43; R 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 < 0.001) and uroflowmetry (B = 53,942; R 2 = 0.99; P < 0.001) were observed during the 8-year period. There was no difference in bladder catheterization during the 8-year period. Urodynamic study (UDS: B = −2,156; R 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.

Purpose: This study was accomplished to evaluate the clinical & radiological results of cementless total hip arthroplasty using a fully hydroxyapatite-coated femoral stem after follow up of at least, 2 years. Materials and Methods: Thirty one hips in 28 patients, who underwent primary total hip arthroplasty using a fully hydroxyapatite-coated femoral stem between september 2007 and May 2009, were followed up for more than 2 years after surgery. The average age of patients was 67 years old, and the average duration of follow up was 35 months. Preoperative diagnosis was 17 cases of osteonecrosis and 10 cases of femoral neck fracture. Clinical evaluation was done by Harris hip score (HHS). Radiological evaluation was done in terms of stability of components, subsidence of femoral stem and occurrence of osteolysis. Results: The average of HHS improved from 34.3 preoperatively to 82.6 at final follow-up. Radiologically, fixation by bony ingrowth was 23 cases(74%) and fibrous ingrowth was 8 cases(26%). Subsidence was within 2-4 mm and occurred within 6 weeks in all 5 cases. There were 4 cases of intra-operative femoral fracture, 1 case of superficial infection. Conclusion: Short-term clinical and radiological results of cementless total hip arthroplasty using a fully hydroxyapatite-coated femoral stem were not good enough. Radiologically, bony ingrowth were no more than 74%. Therefore, longer-term follow up would be necessary.
