Abstract

Abstract: 【Abstract】 Objective We compared the safety and efficiency of diode laser enucleation with that of bipolar plasmakinetic enucleation for the treatment of large volume prostate (>80ml). Methods From June 2012 to January 2014，A total of 70 patients with lower urinary tract symptoms associated with large volume prostate were included in our study. Of these, 35 patients were treated with diode laser enucleation of the prostate. No significant differences were observed in the pre-operative data. All patients were preoperatively assessed and evaluated at 3, 6, and 12-months. Perioperative data and postoperative outcomes were compared. Immediate and late complications were also assessed. Results Both groups displayed significant improvements in IPSS, QoL and Qmax 12 month after surgery. However, we identified there was no significant differences between the two groups in the follow-up data (P>0.05). Patients treated with diode laser showed a lower risk of blood loss [(0.92 ± 0.43)g/dl vs (1.24 ± 0.55)g/dl], as well as shorter bladder irrigation [(28.9 ± 14)h vs（38.5 ± 16.6）h] and catheterization times [(2.6 ± 1.8)d vs (3.8 ± 2.3)d]. A larger amount of prostate tissue was retrieved in the DiLEP group, but the operation time of the diode laser group was longer than that of the bipolar plasmakinetic enucleation group [(123.5 ± 27.2)min vs (102.7 ± 20.4)min]. There was no significant difference in the rate of postoperative urinary retention, blood transfusion, reoperation and incidence of stress urinary incontinence (P>0.05). However, the diode laser group was significantly superior to bipolar plasmakinetic group in terms of the irritative symptoms and ejaculatory function in the postoperative period. Conclusions DiLEP provides more widely application range, less risk of haemorrhage, reduced bladder irrigation and catheter indwelling duration as well as reduced hospital stay. Diode laser enucleation of the prostate is a safe and effective method for the transurethral management of prostates larger than 80 ml.
