Use of the way to find and manage renal pedicle along the ureteral ascending method in retroperitoneosocpic radical nephrectomy / 中华泌尿外科杂志

ABSTRACT

Objective To explore the operating skills of finding and dissecting renal pedicle in retroperitoneosocpic radical nephrectomy.Methods From April 2011 to April 2015,224 patients with renal tumors were treated by retroperitoneosocpic radical nephrectomy.Along the ureteral ascending methodis used to find renal pedicle for 126 cases(the research group)First found ureter in the iliac crest,the ureter was nearest psoas major here and waseasy to find.Along the ureteral upward until to the renal pelvis and the superior border of renal pelvis is the renal pedicle.77 male and 49 female cases,Age 42 to 84 years,(56.6 ± 9.0) years old on average.Sixty-nine tumors were located in left kidney,and 59 in the right kidney.The mean diameter of renal tumor was(5.3 ± 1.1)cm.There were 25 cases of T1a N0 M0,75 T1b N0 M0,23 of T2 N0 M0,3 of T1bN1M0.Over the same period uplift in he kidney central method is used to find renal pedicle for 98 cases.64 male and 34 female cases,Age 27 to 81 years,(57.9 ± 8.3)years old on average.52 tumors were located in left kidney,and 46 in the right kidney.The mean diameter of renal tumor was (5.5 ± 1.4)cm.There were 19 cases of T1aN0M0,61 T1bN0M0,16 of T2N0M0,2 of T1bN1 M0.Results The differences were significant for Looking for renal pedicle time(2.2 ± 1.1 vs.4.5 ±2.0) min,operation time (73.7 ±67.3 vs.90.1 ±87.5)min,hemorrhage volume(69.8 ±42.7 vs.89.7 ±89.2) ml,the incidence of complications (3 vs.9) between the study group and the control group (P ＜ 0.05).The difference were not significant in postoperative hospital stay (7.5 ± 0.8 vs.7.3 ± 0.8) d,exhaust time (2.1 ± 0.6 vs.2.2 ± 0.6) d between two group.All the operations were performed successfully in the research group,with no conversion to open and transfusion.Major complications included 3 cases of vessel injury.Hemostasis was performed with metal clips and suture.In the control group,ena cava rupture in 3 cases,left lumbar veins rupture in 3 cases,retroperitoneal hematoma in 2 case,mild pulmonary embolism in 1 case.two case performed open operation owing to vena cava rupture.The vena cava rupture transit open surgery in 2 cases,and Hemostasis was performed with metal clips in 1 case of vena cava rupture and on the left side of the lumbar veins rupture was managed by suture,titanium clips and bipolar electrocautery;Retroperitoneal hematoma improved by conservative treatment;Pulmonary embolism improved by medical consultation after thrombolysis.Conclusions Retroperitoneosocpic radical nephrectomy with the method of along the ureteral ascending was safe and could quickly locate and ligate the renal pedicle,and shorten operation time,reduce postoperative complications.
