title: Laser-assisted bipolar transurethral resection of the prostate with the oyster procedure for patients with prostate glands larger than 80 mL.
abstract: OBJECTIVE
  To evaluate the safety and efficacy of diode laser-assisted bipolar transurethral resection of the prostate (TURP) with an oyster procedure for large prostate glands (>80 mL).
  
  
  METHODS
  A total of 43 men who presented with lower urinary tract symptoms because of large prostate (>80 mL) obstruction were enrolled in our study. All of these patients underwent the oyster procedure. Measurements included the urinary flow rate, symptom score, duration of catheterization, length of hospital stay, and urinary flow rate. All patients were re-examined 3, 6, and 12 months after surgery.
  
  
  RESULTS
  The patients who underwent oyster procedures experienced good and durable subjective and functional outcomes for 1 year. Small changes in hemoglobin were noted, and no patients needed blood transfusions. No cases of TURP syndrome were noted. Bladder neck contracture was noted in 2 patients (Clavien-Dindo grade III) because of subtrigonal injury during prostate enucleation, and the other complications were minor (Clavien-Dindo grade I to II).
  
  
  CONCLUSIONS
  The oyster procedure is a safe and effective procedure for large prostates (>80 mL).
