Vào lúc kết thúc của thủ tục, dụng cụ được lấy ra, bàng quang bị rút ra, và bệnh nhân được quan sát thấy. Không có ống thông Foley là yêu cầu vào cuối điều trị, và bệnh nhân có thể được thải một khi họ đã hủy bỏ. Nếu bệnh nhân không thể tự mất hiệu lực, một ống thông được đặt cho 1-7 d. | 102 Donahue and Costa perature of 85-100 C at the core of the necrotic lesion. Advances in RF generator technology have allowed for more accurate delivery of energy to achieve and maintain a minimum temperature of 50 C for at least 2 min to ensure that necrotic lesions are as large as possible 9 . At the conclusion of the procedure the instrument is removed the bladder is drained and the patient is observed. No Foley catheter is required at the end of the treatment and patients can be discharged once they have voided. If the patient is unable to spontaneously void a catheter is placed for 1-7 d. Discharge medications include antibiotics and antiinflammatory agents both of which are continued for several days after the procedure 13 18 . CLINICAL TRIALS The first clinical trial to report early experience with TUNA for the treatment of BPH was performed by Schulman and Zlotta 13 . Their experience treating 20 patients with TUNA and describing the results demonstrated that TUNA could provide improvement in peak flow rate quality of life and I-PSS at 6 mo after treatment. The initial United States trial evaluated 12 patients and also demonstrated significant improvement in both peak flow rates and quality of life parameters at 6 mo patients in this study also experienced a significant decline in maximum detrusor pressures and detrusor opening pressures 18 . Roehrborn et al. described the results of a prospective 12-mo multicenter trial of130 patients undergoing TUNA. At the 12-mo evaluation I-PSS had decreased from to p peak flow rates had increased from mL s to mL s p and quality of life had improved significantly. One treatment plane was used for 38 of patients two planes were used in 51 and three planes were used in 14 . All patients received intraurethral lidocaine also received oral anxiolytics also received parenteral sedation and 7 also received parenteral analgesics. Nearly 60 of patients did not require a urinary .
