Abstract: Objective To explore the clinical experience of the treatment of T1 stage renal tumor by retroperitoneal laparoscopic anatomically programmed partial nephrectomy. Methods The clinical data of 30 patients with T1 stage renal tumor who underwent laparoscopic anatomically programmed partial nephrectomy were analyzed retrospectively. The operation time, renal warm ischemia time, postoperative drainage volume, drainage tube extraction time, time in bed, postoperative hospital stay and short-term postoperative complications were recorded. Results All the operations were completed successfully. The average operation time was (72.63 ± 16.62) min, the average renal warm ischemia time was (19.67 ± 5.12) min, the average postoperative drainage flow was (40.66 ± 15.36) ml, the average drainage tube removal time was (1.70 ± 0.45) d, the average time in bed was (1.80 ± 0.70) d, and the average postoperative hospital stay was (4.70 ± 1.40) d. All patients had no complications such as bleeding, progressive hematuria and urinary fistula. Conclusions Laparoscopic anatomically programmed partial nephrectomy is safe and effective in reducing the risk of renal wound bleeding and time in bed. It is safe and reliable for the treatment of T1 stage renal tumor and worthy of clinical promotion. However, there are higher requirements for the surgeon＇s endoscopic suture technique.
