Single-port transumbilical laparoscopic nephrectomy: initial clinical experience of 3 cases / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the safety and efficacy of single-port transumbilical laparoscopic nephrectomy.</p><p><b>METHODS</b>From December 2008 to August 2009, we have performed three cases of single-port transumbilical laparoscopic nephrectomy of nonfunctioning renal by Tri-Port system. Among three patients there were two cases of UPJO and one case of upper ureteral obstruction. Involved kidneys were not visualized in IVU and the GFR were not more than 0.90 ml/s. Tri-Port system was inserted transperitoneal through a 2 cm umbilical incision. The flexible grasper, scissors were used in addition to standard laparoscopic equipment. Renal pedicle was divided by Endoscopic Linear Stapling device. Specimens were extracted through the incision.</p><p><b>RESULTS</b>The first and second case were successful, and the operation time were 85 min and 165 min. The bleeding volume were 50 ml and 100 ml. The discharge time after operation was 3 days and 5 days, respectively. The third case was converted to open surgery because of the edema and adhesion of renal pedicle. At 3 weeks of follow-up, the incisions were hidden in the umbilicus with good cosmetic benefit.</p><p><b>CONCLUSIONS</b>This new method is technically feasible, which combined with these advantages of less trauma and more cosmetic benefit. However, more special instruments and long learning curving may be needed for those surgeons, who are going to carry out it.</p>
