Effect of auxiliary trocar on obese patients treated with retroperitoneoscopic radical nephrectomy / 中华泌尿外科杂志

ABSTRACT

Objective To evaluate the effect of auxiliary trocar located on various positions on obese patients treated with retroperitoneoscopic radical nephrectomy.MethodsRetrospective analysis was performed for 61 consecutive obese patients who underwent retroperitoneoscopic radical nephrectomy for localized renal cell carcinoma at our institution from March 2004 to December 2010.An auxiliary trocar was placed into retroperitoneal space according to the position of tumor.It was placed infro-costal magin in the mid-axillary line with uppre-median pole tumor,and 4 cm medial to mid-axillary line and 1 cm cephalad to illac spine with lower-median pole,respectively.ResultsAll 61 patients were completed successfully with no conversion to open surgery.Mean operating time was ( 153.1 ± 23.5 ) min.Mean estimated blood loss was (57.6 ±29.7) ml.Mean hospital stay after operation was (5.7 ±2.6) d.The rupture of peritoneum and liquefaction of fat were occurred in 5 and 4 patients respectively.There was no major intraoperative and postoperative complications occurred.Conclusions Reasonable position of the auxiliary trocar according to the tumor's location would be safe and feasible on obese patients treated with retroperitoneoscopic radical nephrectomy.Obese patients with localized renal cell carcinoma would better benefit from minimally invasive procedure.
