Laparoscopic nephron sparing nephrectomy / 中华泌尿外科杂志

ABSTRACT

Objective To explore the safety and efficacy of laparoscopic nephron sparing nephrectomy for renal tumor. Methods The data of 72 patients diagnosed as renal rumor and treated with laparoscopic nephron sparing nephrectomy were retrospectively analyzed.Procedure detailed as followingfirstly,the renal tumor was exposed completely after routine institution of 4 passages;secondly,the tissue 3 cm around the tumor was labeled and then incised using cool scissors after Bulldog occlusion of the renal artery;thirdly,the lesion was covered with anti-bleeding gauze and then intermittently sutured using 1-0 absorbable Dixon suture and crossing Hem-o-lok. Results Operation time was 90-190 min,with warm ischemia time 12-40 min.Bleeding volume was 20-600 m1.with one intra-operative infusion and 4 post-operative infusions.Pathological diagnosis was clear cell RCC in 52 cases,angiomyolipoma in 14,chromophobe RCC in 5,and collective duct cancer in 1 case.Hospitalization time was 5-12 days.With 1-52 months follow-up,no tumor recurrence and metastasis was observed. Conclusions Treatment by laparoscopic nephron sparing nephrectomy for renal tumor could be safe and efficient,but operative experiences and skills are needed.The method of intermittent suture and crossing Hem-o-lok could be useful to shorten the operation time and reduce the complications.
