Abstract:
Objective:To investigate the technical points and clinical effect of thulium fiber laser lobes-enucleation of the prostate (ThuLLEP).Methods:A total of 90 patients underwent ThuLLEP and plasmakinetic enucleation of prostate (PKEP) in our hospital from November 2018 to December 2020 were collected. The age of patients in the two groups was (67.7±6.8) years and (65.7±7.1) years, the prostate volume was 56.0 (46.0-83.5) ml and 61.0 (53.5-79.5) ml, the serum PSA was 3.6 (2.2-6.0) ng/ml and 4.4 (1.8-7.3) ng/ml, the international prostate symptom score (IPSS) was 27 (22-31) and 28 (23-30), the quality of life score (QOL) was 5 (5-6) and 5 (5-6), the maximum urinary flow rate (Q max) was (8.5±5.7) ml/s and (7.8±3.8) ml/s, the post-void residual volume (PVR) was 127 (47-250) ml and 100 (27-209) ml. The differences had no statistical significance ( P>0.05). The glands were bluntly dissected to establish the surgical capsule plane on both sides of the verumontanum after the verumontanum being located. And then the middle lobe was removed. The glands formed grooves at 12 o'clock after vaporization, which served as anatomical marker. The left and right lobes were removed step by step. Finally, tissue crushing was performed. The PKEP group was enucleated by three lobes enucleation. Perioperative indicators were compared between the two groups. Results:All the operations were completed successfully. The median operative time in ThuLLEP and PKEP groups was 60 (50-73) minutes and 75 (60-100) minutes, the postoperative bladder irrigation time was 2.8 (2.3-3.6) d and 3.8 (2.6-4.7) d, the catheter indwelling time was 4.1 (3.7-4.9) d and 4.9 (4.7-6.0) d, the postoperative hospital stay was 5 (4-6) d and 6 (5-7) d. The decreased hemoglobin was 8.0 (1.5-14.5) g/L and 15.0 (6.5-21.0) g/L. The differences had statistical significance ( P<0.05). Follow-up was performed for 6 months after surgery. The median IPSS score of the two groups was 5 (2-11) and 6 (3-9), the QOL score was 1 (1-2) and 1 (1-2) respectively, which had statistical significance compared with the preoperative parameters ( P<0.05), but no statistical significance between the two groups ( P>0.05). The ThuLLEP group had 1 case of postoperative blood transfusion, 1 case of transient urinary incontinence and 2 cases of urethral stricture. The PKEP group had 1 case of fever and blood transfusion, 3 cases of transient urinary incontinence and 3 cases of urethral stricture. Conclusions:ThuLLEP has definite clinical effect because of less bleeding, quicker recovery and fewer complications. The relatively simple operation steps are beneficial for beginners to master.
