Prostatic enucleation by laser controller was performed in 66 patients (LC-THuLEP group). The prostatic urethral mucosa was cut into Ω shape at 0.5 cm in front of the verumontanum to expose the prostate capsule, and then the fiber was retracted into the laser controller. Push the gland directly between the prostate gland and the prostate surgical capsule and expand along the capsule by the laser controller. In case of bleeding or prostate adhesive cord, the fiber was extended to coagulate or cut off, and the prostate was eventually en bloc removed. THuLEP by sheath was performed in 62 cases (THuLEP group). The ages of patients in LC-THuLEP group and THuLEP group were (71.00±8.72) years and (70.32±7.80) years, respectively. The prostate volumes were (74.80±40.88) ml and (73.14±36.31) ml, respectively. Prostate specific antigen (PSA) was (4.67±4.99) ng/ml and (4.89±4.59) ng/ml, International Prostate Symptom Score (IPSS) was (19.48±5.30) points and (18.50±5.05) points, respectively. The quality of life (QOL) scores were (4.17 ± 0.78) points and (4.18± 0.67) points, the maximum urine flow rate (Q n max) was (9.82± 2.58) ml /s and (9.98± 2.91) ml/s, respectively. Postvoid residual (PVR) was (60.20±39.19) ml and (61.11±52.83) ml, respectively. The international index of erectile function (IIEF-5) score was (5.58±4.50) and (5.60±4.16), respectively.There was no significant difference in preoperative baseline data between 2 groups (n P>0.05). The operation time, the reduced level of hemoglobin, the weight of removed tissue, The time to postoperative bladder irrigation, the time to indwelling catheter and complications were compared between the two groups. IPSS, QOL score, Qn max, PVR, and complications were compared between the two groups at 1, 3 and 6 months after surgery, while IIEF-5 score were compared only at 6 months after surgery.n Results:The operative time of LC-THuLEP group and THuLEP group was (71.85±25.68) min and (80.65±29.64) min, respectively, and the decrease of postoperative hemoglobin was (6.42±9.89) g/L and (9.47±10.79) g/L, respectively, the weight of the removed tissue was (56.73±31.21) g and (48.11±24.50) g, respectively, and the time to postoperative bladder irrigation was (14.73±2.71) h and (16.06±2.71) h, respectively, the time to indwelling catheter was (4.41±1.92)d and (4.31±1.66)d, respectively, with no statistically significant differences between the two groups. IPSS scores of LC-THuLEP group were (6.52±2.46) points, (5.83±2.43) points and (5.30±2.49) points at 1, 3 and 6 months after surgery, respectively. QOL scores were (2.36±0.85) points, (2.27±1.02) points and (1.98±0.77) points, Qn max were (22.89±2.41) ml/s, (23.61±2.62) ml/s and (23.83±3.53) ml/s, respectively. In THuLEP group, IPSS were (7.60±1.89) points, (6.86±1.81) points and (6.44±1.78) points at 1, 3 and 6 months after surgery, and QOL scores were (2.68±0.67) points, (2.74±1.01) points and (2.35±0.68) points, respectively. Qn max were (21.31±2.52) ml/s, (22.13±2.51) ml/s and (22.11±2.49) ml/s, respectively. Those indexes (except Qmax at 6 months)were better in LC-ThuLEP group than THuLEP group, and the differences were statistically significant (n P0.05).n Conclusion:Compared by sheath, THuLEP by laser controller could be a safe and effective surgical method with better curative effect and lower complication rate.
