ABSTRACT
Objective To report the safety and efficacy of partial nephrectomy (PN) in 56 patients with renal tumors. Methods A retrospective analysis was performed for 56 patients who were treated with PN.Patients were divided into two groups according to the occlusion time.The occlusion time for Group 1 was≤30 min in 28 cases,and Group 2>30 min in 28 cases.All patients underwent pre-and post-operation 99Tcm-diethylenetriamine pentoacetic acid renal scintigraphy, to determine the renal glomerular filtration rate (GFR).The GFR values, amount of blood loss during operation,operative time,postoperative hospital stay and the complications rate were compared between the two groups prior to surgery and one week and six months post-surgery.All patients were followed-up.Results The average follow-up time was 36 (30-48) months.The overall survival rate and tumor recurrence-free survival rate were 100% and 98%.There was no significant difference between vessel clamp time≤30 min and>30 min in the amount of intraoperative blood loss,operative time,postoperative hospital stay and complications rate,P values were 0.266,0.487,0.879 and 1.000.The preoperative and 1 week postoperative GFR values of the two groups were (42.9±4.9) and (34.2±4.9),(42.8±5.6) and (30.4±5.2) ml/min.The difference was significant(P=0.007).The GFR values were (41.2±4.3)ml/min at 6 months after surgery for Group 1,compared with that before surgery,but the difference was not significant (P>0.05).While the GFR values were (38.1±5.0) ml/min for Group 2,and the GFR for Group 2 did not recover to the preoperative level (P=0.001). Conelusions PN for renal tumors could be a safe and effective treatment option.The damage on renal function could be minimal when the renal artery clamping time is controlled to within 30 min.
