A Novel Modification of Transurethral Enucleation and Resection of the Prostate in Patients With Prostate Glands Larger than 80 mL: Surgical Procedures and Clinical Outcomes

Abstract

To evaluate the efficacy and safety of the modified transurethral enucleation and resection of the prostate (M-TUERP) vs the conventional bipolar transurethral resection of the prostate (B-TURP) for the treatment of prostates larger than 80 mL. From April 2012 to May 2014, 86 patients with a prostate volume of >80 mL were divided into 2 groups to undergo M-TUERP and B-TURP. In the M-TUERP group, we proposed combining the 12-mm trocar suprapubic cystostomy and using the techniques of "umbrella-shaped resection," "point resection," and "segmental enucleation" to modify the transurethral enucleation and resection of the prostate procedure. The perioperative clinical data were recorded and analyzed. There were no significant differences in preoperative characteristics between the 2 groups. Both groups were similar with the operative time. The M-TUERP group was significantly superior to the B-TURP group in terms of the weight of the resected tissue, the mean intraoperative bladder pressure, hemoglobin decrease, bladder irrigation duration, and urethral catheterization time. No transurethral resection syndrome and incontinence occurred in either group. Compared with the B-TURP group, none of the patients in the M-TUERP group suffered blood transfusion, clot retention, recatheterization, dysuria and reoperation. At the 3-year follow-up, patients who underwent M-TUERP had better international prostate symptom scores, maximum urinary flow rates, and quality of life scores. Our modification of the transurethral enucleation and resection of the prostate procedure is a safe and effective method for the surgical treatment of large-volume benign prostatic hyperplasia. It can simplify the surgical procedures, reduce complications, lower difficulties and shorten the learning curve. At 3-year follow-up, the M-TUERP shows a superior and durable clinical outcome than the B-TURP.
