药物成份或治疗方案详述: |
从改良犁形电极前列腺腕除术,双极等离子经尿道前列腺电切术,钬激光前列腺剜除术,三种术式中随机选取一种前期筛选入组的前列腺增生患者进行前列腺切除。其中具体的“前列腺尖部尿道黏膜预离断”术式如下:患者取膀胱截石位,面向患者头部,将前列腺沿矢状面分为1-12点。先在12点位置标记尿道切除位置并切开尿道。在5点位置沿着前列腺左叶和中叶的交汇处找到左叶的包膜层面(利用电极的电凝功能并施加适当压力,尿道粘膜很容易被分离),继而显露前列腺左叶尖部,同法于7点方向显露右叶。沿精阜近端6点方向切开尿道,进入前列腺中叶包膜层面,使其与其他两叶平面相连。至此三个腺叶的远端边界和包膜平面都已显露。沿着 5 点到 12 点方向,用电凝标记前列腺尖部尿道切缘并切开。同理从7点到 12 点方向切开尖部尿道。紧贴前列腺尖部腺体,沿包膜层面分离,直至将前列腺尖部完全游离,完成尖部尿道预离断。从5点到12点方向,继续沿包膜层面游离左叶。由于改良犁型电极具有极佳的硬度,以“边推边剜”的方式可以轻松分离腺体,在电凝的预止血作用下,内镜视野始终保持清晰。如遇纤维条索,可直接切断。切除腺体时,需要在鞘的远端用喙持续顶起游离腺体,以便更好地暴露平面,并在直视下保持张力。沿着包膜层面逆时针分离腺体,直到 12 点方向,并继续向膀胱颈方向延伸。从12点到2点区域切开膀胱黏膜,进入膀胱腔。然后,沿膀胱颈粘膜边缘从2点方向到6点方向继续切割,并注意保持膀胱颈完整。此时,除与中叶交界处外,左叶已完全游离。同样,中叶和右叶也从 5 点方向顺时针逐渐分离到 12 点方向,最后在 12 点方向会师。当腺体较大时,可在中叶和右叶部分离断后,将左叶游离部分推入膀胱腔,从而增加前列腺窝的手术空间。也可直接将左叶与中叶先离断,游离后并分别推入膀胱腔。检查尿道切缘和前列腺腔内,修整创面,彻底止血。使用组织切除器,粉碎并吸出腺体。 |

Description for medicine or protocol of treatment in detail: |
Patients with benign prostatic hyperplasia who were pre-screened and enrolled were randomly assigned to undergo one of three surgical procedures: modified plow-shaped electrode transurethral resection of the prostate, bipolar plasma transurethral resection of the prostate, or holmium laser enucleation of the prostate. The specific procedure for "pre-dissection of the urethral mucosa at the apex of the prostate" is as follows: The patient is positioned in the lithotomy position, with the surgeon facing the patient’s head. The prostate is divided into 12-point segments along the sagittal plane. First, mark the urethral resection site at the 12 o’clock position and incise the urethra. At the 5 o’clock position, locate the capsular plane of the left lobe along the junction of the left and middle lobes of the prostate (using the electrocoagulation function of the electrode and applying appropriate pressure, the urethral mucosa can be easily dissected), thereby exposing the apex of the left lobe. Use the same method to expose the right lobe at the 7 o’clock position. Incise the urethra at the 6 o’clock position along the proximal aspect of the verum montis to enter the capsular plane of the middle lobe of the prostate, connecting it to the planes of the other two lobes. At this point, the distal borders and capsular planes of all three lobes are exposed. Using electrocoagulation, mark and incise the urethral margin at the apex of the prostate from the 5 o’clock to 12 o’clock positions. Similarly, incise the urethra at the apex from the 7 o’clock to 12 o’clock positions. Adhering closely to the glandular tissue at the apex of the prostate, dissect along the capsular plane until the apical portion is completely mobilized, thereby completing the pre-separation of the apical urethra. Continue mobilizing the left lobe along the capsular plane from the 5 o’clock to 12 o’clock direction. Due to the excellent rigidity of the modified plowshare electrode, the glandular tissue can be easily dissected using a "push-and-scrape" technique; with the hemostatic effect of electrocoagulation, the endoscopic field of view remains clear throughout. If fibrous bands are encountered, they may be cut directly. When resecting the gland, use the beak to continuously lift the dissected gland at the distal end of the sheath to better expose the dissection plane and maintain tension under direct visualization. Dissect the gland counterclockwise along the capsular plane until the 12 o’clock position, then continue toward the bladder neck. Incise the bladder mucosa from the 12 o’clock to 2 o’clock area to enter the bladder lumen. Then, continue cutting along the edge of the bladder neck mucosa from the 2 o’clock to 6 o’clock direction, taking care to preserve the integrity of the bladder neck. At this point, the left lobe is completely mobilized except at the junction with the middle lobe. Similarly, the middle and right lobes are gradually dissected clockwise from the 5 o’clock to 12 o’clock direction, finally converging at the 12 o’clock position. When the gland is large, after the median and right lobes have been partially dissected, the mobilized portion of the left lobe may be pushed into the bladder cavity to increase the operative space in the prostatic fossa. Alternatively, the left lobe and median lobe may be dissected and mobilized first, then pushed into the bladder cavity separately. Inspect the urethral resection margin and the prostatic cavity, trim the wound edges, and ensure thorough hemostasis. Use a tissue resection device to pulverize and aspirate the glandular tissue. |
