Bladder outlet obstruction treated with transurethral ultrasonic aspiration

摘要

Abstract: Fifty-nine males with bladder outlet obstruction were treated with transurethral ultrasonic aspiration of the prostate. Utilizing a 26.5 French urethral sheath, surgery was accomplished with a 10 French, 0-700 micron vibration level ultrasonic tip with an excursion rate of 39 kHz. Complete removal of the adenoma was accomplished, followed by transurethral electrocautery biopsies of both lateral lobes to compare pathologic specimens. One-year follow-up revealed satisfactory voiding patterns in 57 of 59 men (96%). Two men developed bladder neck contractures. Pathologic comparisons showed 100% correlation between aspirated and TUR specimens (56 BPH, 3 adeno-carcinoma). Forty-sevel men were active sexually preoperatively (6 with inflatable penile prostheses). Post ultrasonic aspiration, 46 men had erectile function similar to preoperative levels with one patient suffering erectile dysfunction. Forty men (85%) had antegrade ejaculation while 7 (15%) experienced retrograde or retarded ejaculation. No patients were incontinent.!
