2268 PHOTOSELECTIVE VAPORIZATION OF THE PROSTATE WITH THE 80-W KTP-LASER VERSUS TRANSURETHRAL RESECTION OF THE PROSTATE &endash; LONG-TERM RESULTS OF A PROSPECTIVE BICENTER TRIAL

Abstract

were given before, during and after PAE. Pelvic Angio MR was performed before PAE and 200 m nonspherical PVA particles were used in the first 14 patients. In the last 42 patients Pelvic Angio CT was performed before PAE and 100 m PVA particles were used. The control follow-up was performed between 1 and 18 months (mean 8.6 months) after PAE. RESULTS: PAE was technically successful in 56 of the 57 patients (96.4%) and in 3 patients the embolization could be performed only unilaterally. With Pelvic Angio MR and Pelvic Angio CT the common, external and internal iliac arteries could be visualized. The prostate arteries could be shown only by pelvic Angio CT. There were 4 clinical failures (7.1%). In the remaing 52 patients with clinical success, at last follow-up, the mean prostate volume decreased 28.1%, the IPSS decreased 9.8 points, the QoL improved 1.9 points, the IIEF increased 1.8 points and the peak urinary flow increased 6.1 and the PSA decreased 26.1%. There was no deterioration of the sexual function in any patient. Better results were obtained with 100 m PVA particles than with 200 m PVA particles. As complications there was one case of bladder wall ischaemia that was treated by surgical removal, 3 cases of transient urinary retention treated with bladder catheter for 5 days, 6 cases of urinary infection treated with antibiotics and 2 cases of inguinal haematoma. Six patients referred pain during the procedure. One had severe pain, and the remaining 5 patients slight to moderate pain. Fifty-two patients were treated as outpatients and were discharged 4 8 hours after the procedure and four were discharged the next morning (18 hours later). CONCLUSIONS: PAE in patients with symptomatic PBH is safe, with low morbidity, good short and medium term results that are better with 100 m PVA particles.
