[Echographic study of the bladder neck and prostate region after Nd-Yag laser treatment].

The authors describe the ultrasonic images they obtained in the follow up of three groups of patients who were divided according to basic pathology and treated with Nd: Yag Laser with contact (CLAP) and side firing (VLAP) fibers. Next the great differences noted between the results achieved with ultrasonic investigation and those obtained with flowmeter controls and IPSS are presented. The authors discuss the possible causes of these dissonances and hypothesize a new way to evaluate cervico-urethral de-obstruction: no longer an anatomical technique but a functional one.
