The Harbin Medical University nephrectomy score: a quantitative system for evaluating the complexity of laparoscopic retroperitoneal simple nephrectomy.

摘要: BACKGROUND Laparoscopic retroperitoneal simple nephrectomy (LRSN) has been widely accepted as a mainstay option for benign non-functioning kidney. The complexity of the procedure, however, differs and remains subject controversy. OBJECTIVE To develop standardised Harbin Medical University score (HMUNS) system evaluating LRSN complexity. SUBJECTS AND METHODS A total 6 variables with different factors comprising primary diseases, history upper urinary tract surgery, body mass index (BMI), surgeon's learning curve, kidney volume, Mayo Adhesive Probability (MAP) scores were included in HMUN score. 95 consecutive patients who underwent at our institution divided into low (2 to points) high (7 17 groups HMUNS investigated differences operative time (OT), estimated blood loss (EBL), postoperative hospitalisation (PHT), rate intraoperative conversion open Clavien-Dindo classifi cation (CDC) between both groups. RESULTS Longer mean times (193.2±69.3 min vs. 151.9±46.3 min, p <0.05), more median (100.0mL 50.0mL, higher rates surgery (1.2% 25%, <0.05) observed high-complexity group (n=12) than low-complexity (n=83). However, there no remarkable two related baseline characteristics, post-surgical times, complications. CONCLUSIONS can effectively reflect complexity, thus providing quantitative risk estimation treatment decisions. Because some limitations, further well-designed studies are necessary confirm fi ndings. Patient summary: HMUNS, including BMI, MAP score, provide an effective tool evaluate LRSN.
