Application of Laparospic Ultrasonography in Surgery of Small Renal Cell Carcinoma

Purpose: : To assess the clinic value of application of laparospic ultrasonography (LU) in partial nephrectomyof small renal cell carcinoma. Materials and
Methods: From 2007 to 2011, 28 small renal cell carcinomapatients in ou clinic underwent laparoscopic partial nephrectomy with LU. For comparison with preoperativeconventional ultrasound and CT, we collected ultrasonic performance of the affected side kidney, renal tumorlocation, size, echo change, blood supply situation and the relationship with the surrounding tissue.
Results:LU could more clearly show the tumor interior structure and blood supply, as well as the relationship with thesurrounding tissue. It also can provided doctor assistance with real-time tumor resection, reducing operativecomplications.
Conclusions: LU can clearly show tumor internal structure and blood supply, which is helpfulfor explicit diagnosis. Moreover, it supplies accurate information for surgeons and assists surgery. ThereforeLU has an important guiding value in partial nephrectomy for small renal cell carcinoma.
