Abstract:
Objective To report on our experience with laparoscopic nephron-sparing surgery forthe treatment of renal tumors,and to seek the safe and effective techniques and methods. Methods FromJune 2003 to June 2005,16 patients (5 men and 11 women) with small exophytic solid renal masses weretreated by transperitoneal laparoscopic wedge resection in our hospital.The mean age was 46 years (range,29 -56 years).The mean tumor size of renal cell carcinoma (5 cases) and hamartoma (11 cases) was2.0 -3.5 cm and 3.0 -5.5 cm,respectively, in diameter. One case of hamartoma had secondary bleeding.Wedge resection of the tumors was performed quickly with scissor,and hemostasis was achieved by intra-ab-domen suturing and knotting. Results All the procedures were finished laparoscopically with no conver-sion to open surgery.The mean operative time was 104 min (range,70 -150 min);mean hot bloodless timewas 21 min(range,14 -32 min);mean blood loss was 158 ml (range,50 -700 ml).The pathologic exami-nation showed negative surgical margin in 5 cases of renal cell carcinoma.Postoperatively,no urinary leakageand secondary bleeding occurred,and the renal function was normal in all the 16 cases.The patients weredischarged 7 d after operation.Follow-up was 1 month to 1 year.Neither distant nor local recurrences wereobserved by the last follow-up date on B-ultrasound,IVUand CTat follow-up. Conclusions Laparoscopicnephron-sparing surgery for renal tumors is a minimally invasive procedure with less blood loss,less pain andfewer complications.Reliable non-traumatic kidney vessel control is the basic method of this operation.Sharpresection without smog and rapid renal incision suturing can reduce the renal hot bloodless time.
