Transurethral resection of prostate is the gold standard for the surgical management of benign prostate hyperplasia. Bipolar devices allow transurethral resection of prostate with saline irrigation, which lessens water intoxication and negates the need for diathermy pad and unwanted stimulation of the obturator nerves and cardiac devices. Several randomized clinical trials compare the various bipolar devices with conventional monopolar ones. For this review, we search all peer-reviewed published literature databases and present the evidence from them to substantiate its advantages and disadvantages.
Of the various types of bipolar devices, Gyrus has the longest clinical experience. Bipolar transurethral resection of prostate overcomes the shortcomings of bipolar transurethral prostate vaporization, which includes the absence of histology, postop irritative urinary symptoms and nondurable clinical outcomes. With bipolar transurethral resection of prostate, there is lesser bleeding which leads to shorter resection time and lower fluid absorption. This also enables shorter cathterization time and hospital stay. Transurethral resection syndrome has not been observed.
Bipolar transurethral resection of prostate has demonstrated similar clinical efficacy as monopolar transurethral resection of prostate with shorter catheterization and hospital stay. It eliminates the occurrence of transurethral resection syndrome and minimizes bleeding risk. Long term outcomes from these randomized clinical trials will determine the durability of its clinical efficacy and incidence of urethral strictures.
经尿道前列腺切除术是良性前列腺增生手术治疗的金标准。双极设备允许使用生理盐水冲洗进行经尿道前列腺切除术,这可减少水中毒,并消除了对透热垫的需求以及对闭孔神经和心脏设备的不必要刺激。多项随机临床试验将各种双极设备与传统单极设备进行了比较。在本次综述中,我们检索了所有经过同行评审的已发表文献数据库,并展示其中的证据以证实其优缺点。
在各种类型的双极设备中,Gyrus的临床经验最为丰富。双极经尿道前列腺切除术克服了双极经尿道前列腺汽化术的缺点,后者包括缺乏组织学检查、术后刺激性尿路症状以及临床效果不持久。采用双极经尿道前列腺切除术时,出血较少,这导致切除时间缩短和液体吸收减少。这也使得导尿时间和住院时间缩短。未观察到经尿道切除综合征。
双极经尿道前列腺切除术已证明与单极经尿道前列腺切除术具有相似的临床疗效,但导尿和住院时间更短。它消除了经尿道切除综合征的发生,并将出血风险降至最低。这些随机临床试验的长期结果将决定其临床疗效的持久性和尿道狭窄的发生率。
