Abstract
Purpose:
The twenty-six F sized continuous running irrigation transurethral resection (TUR) system has showed a relatively high risk for inducing postoperative urethral stricture in Korean men. We evaluated the efficacy and safety of recently available 22F continuous running irrigation TUR system for treating benign prostatic hyperplasia (BPH) patients.
Materials and Methods:
A total of seventy patients with severe symptomatic BPH underwent transurethral prostatectomy (TURP). The 26F system was used in 31 cases and the 22F system was used in 39 patients. The total resection weight, the resection rate, and the intraoperative and immediate postoperative complication rates were compared between the 2 groups. The patients were followed for 2 weeks, 4 weeks and 3 months postoperatively to check for the development of urethral stricture.
Results:
The total resection weight was 14.8±9.5gm in the 22F group and 11.2±10.2gm in the 26F group (p> 0.05). The resection rates were 0.24土 0.10gm/min and 0.19±0.11gm/min, respectively. The rate of urethral stricture requiring any type of management was 15.4% (6/39) in the 22F group and 38.7% (12/31) in the 26F group (p く 0.05). Visual internal urethrotomy was performed in 2.6% (1/39) and 9.7% (3/31) of the patients, respectively. Other complications were 1 capsular perforation, 1 TUR syndrome, 1 epididymitis and 1 delayed bleeding in the 22F group, and 1 intraoperative fever and 1 epididymitis in the 26F group.
Conclusions:
TURP using the 22F continuous running irrigation system enabled the surgeon to resect prostate adenoma with a similar speed and effectiveness as compared with the 26F system, and it significantly reduced the risk of urethral stricture. Performing TURP with using this system can be considered as a first line therapy for the BPH patients who require surgery. (Korean J Urol 2006;47:175-179)
