TURP syndrome

A 65-year-old patient comes to an urology outpatient clinic because of a progression of his micturition problems. He has been treated for benign prostatic hyperplasia with alfuzosin for some time. His chief complaints include a delayed need to urinate, intermittent and weak urination, frequent urination at night, incomplete voiding and an involuntary release of urine from an overfull bladder.
