[Single-center experience of robot-assisted laparoscopic nephron-sparing surgery for giant renal hamartoma].

ABSTRACT

The clinical data of 22 patients with giant renal hamartoma in Zhejiang Provincial People's Hospital who underwent robot-assisted laparoscopic nephron-sparing surgery from October 2014 to January 2020 were retrospectively analyzed. All the patients successfully completed the operation. The operation time and renal artery occlusion time was (179±34) min and (19.8±2.5) min, respectively. The intraoperative blood loss was (117±62) ml, and the postoperative hospital stay was (9.0±1.5) d. All cases were confirmed as renal angiomyolipoma by postoperative pathology. No urine leakage, postoperative bleeding and other complications occurred. Postoperative telephone follow-up was performed for 6 to 52 months, and no tumor recurrence on the surgical side was reported.
