The TULIP (Transurethral Ultrasound-guided Laser-Induced Prostatectomy) system combines a real-time ultrasound transducer and a Nd:YAG laser delivery system with a 1.064 micron wavelength within a 22 F urethral probe. The goal is to produce a coagulation necrosis of the prostatic parenchyma, with a subsequent elimination of tissue in the urine. 29 patients have been included in this study, and 13 have a minimal one year follow-up. No complication occurred. 2 patients underwent a transurethral resection of the prostate secondary to the TULIP treatment. All patients complained of irritative urinary symptoms (frequency, burning on urination...) in the days or weeks following the treatment, and suprapubic catheterization tube had to be left in place for a mean duration of 13.8 days. Inclusion/exclusion criteria and evaluation modalities have been the same as in the American national study published elsewhere. At one year, our success rate for at least one criteria has been 84.6%, but only 2 (15%) out of 13 patients have been successful both in symptom score and flow rate.
