A medical team of Dr. SeungJoon Oh, a professor of urology in Seoul National University Hospital succeeded in developing a data-centered surgery of benign prostatic hyperplasia(BPH) and a diagnostic program that allow to calculate the probability of the enlarged prostate gland. In order to know the progress of the BPH, it is necessary to check the degree of the 'lower urinary tract obstruction'. Diagnosis requires an urodynamics test, which measures the flow and pressure by inserting a conduit through the urethra to the bladder and it is time consuming and costly. The new diagnostic program developed by the team has been improved all of those problems by using the results of the urodynamic study, which has been systematically accumulated by Seoul National University Hospital for the last 10 years. Entering age, peak urinary flow, residual urine volume, and prostate volume, which are important indicators of judgment, it is easy to quantify the ‘degree of lower urinary tract obstruction' and ' probability of needing surgery'. The study was published in the recent issue of the International Neurourology Journal, an international journal in the field of urology.
