Objective To investigate the efficacy of nephron-sparing surgery(NSS)for the treatment of renal sinus angiomyolipoma and summarize the surgical experience.Methods The clinical data and follow-up results of 10 cases of renal sinus angiomyolipoma treated during Sep.2014 and Feb.2022 in our hospital were retrospectively analyzed.Result s The patients included 1 male and 9 female.The mean tumor diameter was(5.7±2.8)cm.The RENAL score was 8 in 1 case,9 in 3 cases,10 in 4 cases,and 11 in 2 cases.Retroperitoneal laparoscopic partial nephrectomy was conducted in 3 cases,robot-assisted laparoscopic partial nephrectomy in 3 cases,and open partial nephrectomy by transabdominal approach in 4 cases.All operations were successful.The median operation time was 225(97-340)minutes and the median warm ischemic time was 30.5(5-43)minutes.Two patients underwent renal vein clamping simultaneously,with clamping time of 18 and 29 minutes,respectively.The median estimated blood loss was 200(10-600)mL,and no patients received blood transfusion.The difference between postoperative and preoperative hemoglobin concentration was statistically significant[113(94-130)g/L vs.136(95-150)g/L,P=0.041].The difference between the postoperative and preoperative serum creatinine level was not statistically significant[58(35-89)μmol/L vs.62(39-77)μmol/L,P=0.722].One case suffered lymphorrhagia(Clavien-Dindo grade Ⅰ)and recovered with conservative treatment;1 case experienced local recurrence after a follow-up of 99 months;9 patients recovered uneventfully without any postoperative complications.Conclusion NSS is an effective treatment strategy for renal sinus angiomyolipoma.Complete resection plays a key role.Due to possible recurrence,long-term follow-up is recommended.
