A 71-year-old male patient comes to the hospital after having been previously diagnosed with benign prostatic hypertrophy with urinary obstruction. Due to this condition, the patient is experiencing increased urination, straining during urination, and a continual feeling of fullness after the bladder has been emptied. The physician performs a cystourethroscopy to examine the condition of the bladder and urethra, and then subsequently performs a UroLift transprostatic implant procedure using three adjustable implants.
