Two-year Follow-up in Bipolar Transurethral Enucleation and Resection of the Prostate in Comparison with Bipolar Transurethral Resection of the Prostate in Treatment of Large Prostates. Randomized Controlled Trial

Abstract

ObjectiveTo assess the safety and long-term efficacy of bipolar transurethral enucleation and resection of the prostate (B-TUERP) in the treatment of enlarged prostate in comparison with bipolar transurethral resection of the prostate (B-TURP). Materials and MethodsFrom June 2015 to March 2019, a total of 240 patients with enlarged prostates of more than 80 gm were randomized into 2 groups, each containing 120 patients. Patients in group A were subjected to B-TUERP while those in group B underwent B-TURP. The perioperative data and postoperative outcomes followed at 1, 6, and 24 months after surgery at which points they were analyzed, and a comparison made between the 2 groups. ResultsThere were no significant differences in the preoperative parameters of the 2 groups. Comparing with B-TURP, B-TUERP had longer operative time (105.09 ± 31.08 vs 61.09 ± 29.28 min), more resected prostatic tissue (50.41 ± 13.07 vs41.12 ± 8.91 g) and had less hemoglobin drop (1.5 vs 2g/dL). In addition, indwelling catheter time, postoperative bladder irrigation duration, and hospital stay were significantly shorter in the B-TUERP group than in the B-TURP group. At 24 month after the procedure, patients with B-TUERP achieved better results of International Prostate Symptom Score (6 vs 7 P = .008), quality of life (1 vs 2, P = .243), maximal flow rate (24.9 ± 5.74 vs 20.09 ± 3.27mL/sec, P = .034), post-voiding residual urine volume (18.64 ± 3.28 vs 24.74 ± 4.02 mL, P = .001), and residual prostate volume (18.64 ± 3.28 vs 20.74 ± 4.02 mL, P < .001). On the other hand, there were no significant differences in postoperative complications between both groups. ConclusionB-TUERP is a more effective modality in the treatment of enlarged prostate compared to B-TURP with almost no variation in safety.
