The TULIP system was the first apparatus designed specifically for laser ablation of the prostate. Laser energy is delivered under ultrasound guidance with the probe moved distally from the bladder neck at the rate of 0.5 to 1 mm/sec. The aim is to produce a deep level of coagulation necrosis. Postoperatively, patients have a suprapubic catheter until they can void comfortably. As of 1994, 2-year results showed a 69% reduction in the mean Boyarsky symptom score (N = 57) v 63% at 6 months (N = 212) and a mean increase in the peak urine flow rate of 68% (N = 46) v 59% at 6 months (N = 195). At present, it is not clear whether TULIP will become commercially available in the United States.
TULIP系统是首个专门设计用于前列腺激光消融的设备。在超声引导下输送激光能量，探头以0.5至1毫米/秒的速度从膀胱颈向远端移动。目的是产生深层的凝固性坏死。术后，患者留置耻骨上导尿管，直到能够舒适地排尿。截至1994年，2年的结果显示，平均博亚尔斯基症状评分降低了69%（N = 57），而6个月时为63%（N = 212），平均最大尿流率增加了68%（N = 46），6个月时为59%（N = 195）。目前，尚不清楚TULIP是否会在美国上市。
