Follow-up data.

Background and objectivesAnatomical endoscopic enucleation of the prostate (AEEP) has revolutionized the surgical treatment of benign prostatic hyperplasia, offering advantages over transurethral prostate resection (TURP). This study aimed to compare the effectiveness of the mushroom technique versus morcellation in en bloc transurethral bipolar prostate enucleation (TUEB) for prostates > 80 mL, hypothesizing that morcellation would reduce operative time.Patients and methodsWe retrospectively reviewed 234 TUEB procedures performed between January 2018 and March 2024 at a tertiary university hospital. Patients were divided into two groups: the mushroom technique group (n = 116) and the morcellation group (n = 118). Demographic and clinical data were collected and outcomes, such as operative time, efficacy, and complications, were analyzed.ResultsThe median operative time was significantly longer in the mushroom cohort (80 [60–90] min) than in the morcellation cohort (60 [50–70] min) (p ConclusionsMorcellation is an efficient method for tissue removal during bipolar prostate enucleation particularly for larger prostates, owing to its shorter operative time and consistent efficacy. Although the mushroom technique is a viable alternative, it is less efficient for larger glands. Nevertheless, both techniques demonstrated similar safety profiles and functional outcomes. Further multicenter trials are required to confirm these findings.

背景与目的 解剖性内镜前列腺剜除术（Anatomical endoscopic enucleation of the prostate, AEEP）已彻底革新了良性前列腺增生的外科治疗方案，相较经尿道前列腺切除术（transurethral prostate resection, TURP）具备显著优势。本研究旨在对比整块经尿道双极前列腺剜除术（en bloc transurethral bipolar prostate enucleation, TUEB）中，蘑菇技术与粉碎术在处理体积＞80mL前列腺时的疗效差异，提出假说：粉碎术可缩短手术时长。
患者与方法 本研究回顾性分析了2018年1月至2024年3月于某三级大学医院开展的234例TUEB手术病例。将患者分为两组：蘑菇技术组（n=116）与粉碎术组（n=118）。收集患者的人口统计学与临床资料，并对手术时长、疗效及并发症等结局指标进行分析。
结果 蘑菇技术队列的中位手术时长为80 [60~90] 分钟，显著长于粉碎术队列的60 [50~70] 分钟（p）。
结论 粉碎术是双极前列腺剜除术中一种高效的组织取出方式，尤其适用于体积较大的前列腺，因其手术时长更短且疗效稳定。尽管蘑菇技术亦是一种可行的备选方案，但对于体积较大的腺体而言其效率稍逊。不过，两种术式均展现出相似的安全性与功能结局。未来需开展多中心临床试验以验证本研究结果。
