ABSTRACT

Objective To evaluate the clinical effect and safety of retroperitoneal laparoscopic partial nephrectomy in treatment of patients with T1b renal carcinoma.Methods Fourteen patients (11 males and 3 females) with T1b renal carcinoma were retrospectively performed.The age of patients was (54.5 ± 9.2)years old,with 8 cases on the left side and 6 cases on the right side.Tumor diameter was (5.1±1.3) cm.All the patients received retroperitoneal laparoscopic partial nephrectomy.Results None of the 14 cases was converted to open surgery.The operation time was (112.0 ± 24.7) min,the intraoperative blood loss was (64.6 ± 15.9) ml,the warm ischemia time was (26.5 ± 9.3) min.The 14 patients were not blood transfusion in intraoperative and postoperative.Postoperative negative pressure drainage placement time was (3.1 ± 1.5)d,lying in bed time was 72 h.Serum creatinine increase was found in 1 case postoperative 12 h,others were no severe complications.Postoperative pathologythe incisal margin of 14 cases were all negative,clear cell carcinoma was in 13 cases,the pathology stage was T1bNoM0;angiomyolipoma of kidney was in 1 case.All the patients were follow-up 3-16 (21.4 ± 9.6) months,all the patients had normal renal function and had no tumor recurrence or metastasis.Conclusion Retroperitoneal laparoscopic partial nephrectomy is safe and reliable for treatment of patients with T1b renal carcinoma.
