腹腔镜超声在肾肿瘤部分切除术中的应用

目的 初步探讨腹腔镜超声在肾肿瘤部分切除术中的临床应用价值.方法 对32例肾肿瘤患者行腹腔镜肾部分切除术,术中行腹腔镜超声探查,观察肿瘤形态、边界、回声、血流等,并与术前常规经腹部超声检查结果进行对比.结果 32例肾肿瘤患者均顺利完成手术.术中腹腔镜超声示恶性肿瘤形态欠规则,边界清,内部回声不均匀,彩色多普勒显示肿瘤内部和(或)周边均可探及较丰富血流信号,明显优于术前常规超声检查.良性肿瘤形态较规则,边界清,内部回声不均匀,彩色多普勒显示肿瘤内可探及少量低速静脉血流,而常规超声检查肿瘤内血流信号不明显.结论 腹腔镜超声较常规超声检查更清晰,有助于术中指导手术步骤及提供准确信息,在腹腔镜肾部分切除术中有重要指导价值.

Application of laparoscopic ultrasonography in partial nephrectomy of renal tumors

Objective To explore the clinical value of laparoscopic ultrasonography (LUS) in partial nephrectomy of renal tumors. Methods Thirty-two patients with renal tumor underwent laparoscopic partial nephrectomy. LUS was performed during the operation to observe the shape, boundary, echo changes and blood supply of the tumor, and the results were compared with normal ultrasonography performed before operation. Results Renal tumors in 32 patients were removed successfully. LUS showed that malignant tumors displayed irregular shape, clear boundary and inhomogeneous echo, and color Doppler ultrasonography showed abundant blood flow within or around the tumor, which provided more information than normal ultrasonography before operation. Benign tumors had regular shape, clear boundary and inhomogeneous echo, and color Doppler ultrasonography showed less slow blood flow in the vein, while normal ultrasonography showed almost no blood flow. Conclusion Compared with normal ultrasonography, LUS can provide more clear images,help to guide the procedure of the operation and provide exact information. LUS is very valuable in laparoscopic partial nephrectomy.
