Multiparametric ultrasound of the prostate: adding contrast enhanced ultrasound to real-time elastography to detect histopathologically confirmed cancer.

Purpose: We prospectively assessed whether a combined approach of real-time elastography and contrast enhanced ultrasound would improve prostate cancer visualization.

Material And Methods: Between June 2011 and January 2012, 100 patients with biopsy proven prostate cancer underwent preoperative transrectal multiparametric ultrasound combining real-time elastography and contrast enhanced ultrasound. After initial elastographic screening for suspicious lesions, defined as blue areas with decreased tissue strain, each lesion was allocated to the corresponding prostate sector.

The impact of real-time elastography guiding a systematic prostate biopsy to improve cancer detection rate: a prospective study of 353 patients.

Purpose: We evaluated whether real-time elastography guided biopsy improves prostate cancer detection compared to conventional systematic gray scale ultrasound guidance.

Materials And Methods: A total of 353 consecutive patients suspicious for prostate cancer were prospectively randomized for real-time elastography (178) or gray scale ultrasound (175). Each patient enrolled in the study underwent a 10-core prostate biopsy.

Lumbar microdiscectomy: subperiosteal versus transmuscular approach and influence on the early postoperative analgesic consumption.

Conventional lumbar microdiscectomy requires subperiosteal dissection of the muscular and tendineous insertions from the midline structures. This prospective, randomized, single center trial aimed to compare a blunt splitting transmuscular approach to the interlaminar window with the subperiosteal microsurgical technique. Two experienced surgeons performed first time lumbar microdiscectomy on 125 patients.
