Abstract
Seven cases of renal tumor treated at our hospital from May 2009 to November 2011 were assigned to undergo laparoscopic ultrasonography assisted laparoscopic partial nephrectomy. The mean operative duration was 109 minutes (range:102-121). And the mean volume of blood loss was 82 ml (range:60-120). All patients had confirmed negative margins. Renal clear cell carcinoma was definitely diagnosed in all cases. Laparoscopic ultrasonography could provide more precise information of renal tumor within renal capsule. Thus it may be used to guide the operation so that tumors are excised more completely, residual tumor tissues avoided and normal renal tissues protected. Key words: Laparoscopic ultrasonography; Laparoscopes
