The duration of the procedure, need for postoperative irrigation, duration of catheterisation, and hospital stay were recorded.</AbstractText><AbstractText Label="RESULTS AND LIMITATIONS" NlmCategory="CONCLUSIONS">The median procedure time was 60 min, postoperative irrigation was necessary in 19 out of 56 patients, and the median duration of catheterisation was 23 hr. At the day of discharge, the mean haemoglobin value decreased by 0.2mg/dl (p=0.13), the average Q(max) improved from 8.1 to 19.3 ml/s (p<0.001), and the PVRU decreased from 152 ml to 57 ml (p<0.05). The blood transfusion rate was 3.6%, and two patients needed a recatheterisation postoperatively (3.6%). After a median follow-up of 9 mo, the IPSS improved from 19.8 at baseline to 8.6 (p<0.001). Four patients had a repeat transurethral resection of the prostate (TURP) during the learning curve, but this was not necessary in any of the later patients. One patient developed a urethral stricture, and another developed a bladder neck contracture.</AbstractText><AbstractText Label="CONCLUSIONS" NlmCategory="CONCLUSIONS">The thulium laser seems to be a suitable tool for the endoscopic treatment of BPH.</AbstractText></Abstract><AuthorList CompleteYN="Y"><Author
