Control Group

Sample size:

干预措施:

对照组采用常规RARP手术,具体步骤简述如下: 1.完成麻醉、体位摆放,建立气腹 3.使用缝扎DVC(Standard DVC, S-DVC)技术控制DVC。S-DVC技术指先对DVC进行缝合、结扎,之后切断DVC,可以保证DVC内血管不会出血。 4.依次分离膀胱颈、输精管和精囊。 5.分离前列腺的背面。 6.处理前列腺蒂并保留血管神经束。 7.分离尿道、完成膀胱颈尿道吻合。 8.根据有无临床指征,进行淋巴结清扫术。 9.机器人移除和伤口缝合。

干预措施代码:

Intervention:

The control group underwent conventional RARP. The key surgical steps are briefly described as follows: 1. Following anesthesia induction and patient positioning, pneumoperitoneum was established. 2. The retropubic space was entered, and the prostate was exposed. 3. The Dorsal Venous Complex (DVC) was controlled using the S-DVC technique. The S-DVC technique involves initial suture ligation of the DVC, followed by its transection, to ensure hemostasis of the vessels within the DVC. 4. The bladder neck, vas deferens, and seminal vesicles were sequentially dissected. 5. The posterior aspect of the prostate was dissected. 6. The prostatic pedicles were managed (or ligated), and the neurovascular bundles were preserved. 7. The urethra was divided, and vesicourethral anastomosis was performed. 8. Lymph node dissection was performed if clinically indicated. 9. The robot was undocked, and wound closure was performed.

Sample size:

干预措施:

新术式组的大部分手术步骤与对照组相似,二者的区别主要体现在处理前列腺腹侧时: 1.采用D-DVC技术控制DVC,具体细节为:首先,适当升高气腹压至16-18mmHg,在较大的气腹压作用下可以防止大部分的静脉出血。之后,在不进行DVC缝扎的情况下离断DVC,观察出血情况,多数情况下仅有少量出血,多为小动脉或较大静脉出血。术者视情况仅对出血位置进行电凝或局部缝扎止血,从而最大程度保留DVC的神经与肌纤维不受破坏。最后,在出血得到安全控制后,降低气腹压至12mmHg左右。 2.在完成D-DVC之后,进行前方括约肌重建,沿用既往文献中使用的方法,具体细节为:首先,使用3/0倒刺线由右至左将膀胱肌纤维缝合到尿道与DVC之间的尿道旁组织上。之后,使用相同缝线将脏筋膜层与逼尿肌裙缝合到覆盖DVC的盆腔内筋膜上,作为新的“耻骨膀胱韧带”。通过上述方式,可以让尿道吻合口获得后方三层筋膜与前方两层筋膜的保护,从而获得更稳定的解剖结构。在完成前重建后,进行尿道-膀胱口吻合。

干预措施代码:

Intervention:

The majority of surgical steps in the novel-technique group were similar to those in the control group, with the primary differences lying in the management of the ventral aspect of the prostate: 1. The D-DVC technique was utilized to manage the DVC. Specific details were as follows: Initially, the pneumoperitoneum pressure was temporarily increased to 16-18 mmHg; this higher insufflation pressure helps prevent most venous bleeding. Subsequently, the DVC was transected without prior suture ligation, and bleeding was observed. In most cases, only minimal bleeding was noted, typically from small arterioles or larger veins. As deemed necessary by the surgeon, only targeted electrocoagulation or local suture ligation was performed at the bleeding sites, thereby maximally preserving the neural and muscular fibers within the DVC from damage. Finally, once hemostasis was safely achieved, the pneumoperitoneum pressure was reduced to approximately 12 mmHg. 2. Following the D-DVC procedure, anterior sphincter reconstruction was performed, adopting a method previously described in the literature. The specific details included: First, using a 3/0 barbed suture, the bladder muscle fibers were sutured from right to left to the periurethral tissue situated between the urethra and the DVC. Subsequently, using the same suture, the visceral fascial layer and the detrusor apron were sutured to the endopelvic fascia overlying the DVC, creating a new "pubovesical ligament." This approach aimed to provide the urethrovesical anastomosis with support from three posterior fascial layers and two anterior fascial layers, thereby achieving a more stable anatomical reconstruction. After completing the anterior reconstruction, vesicourethral anastomosis was performed.
