Abstract: Objective To evaluate the applicative value of intra-operative laparoscopic ultrasonography ( LUS) in laparoscopic partial nephrectomy (LPN) of centrally located para-hilus renal tumors. Methods Clinical date of 4 patients who underwent LPN for centrally located renal tumors with LUS in our hospital during March to July of 2014 were retrospectively analyzed. Two of the patients were operated through abdominal cavity and 2 were operated through retroperitoneum. Indicators such as operation time, blood loss, pathology, incisal margin and so on were assessed. Results LUS showed that malignant renal tumors displayed irregular shape, clear boundary and inhomogeneous echo. Color Doppler ultrasonography showed blood flow within or around the tumors, which provided more information than normal ultrasonography before operation and helped to determine the scope of the renal tumor resection. All cases were confirmed renal cell carcinoma and negative margin with postoperative pathology. Conclusion It is of high clinical value to use LUS in LPN for centrally located renal tumors with real-time image, which helps surgeons to determine the location of the tumor and the position relation between the tumor and vessels and the collection system. At the same time, it also helps to reduce intra-operative hemorrhage, provide negative incisal margin and guarantee the safety of operation.
