Nephrectomy with Autotransplantation-A Key Treasure

Nephrectomy with autotransplantation (NAT) has been performed as an alternative treatment for complex renovascular lesions, intricate ureteral strictures and nephron-sparing surgery in complex renal tumors. : A retrospective observational study was conducted including patients who underwent a NAT from January 2010 to September 2023. Data collected included surgery indications, surgical technique, complications according to Clavien-Dindo classification and mean hospital stay. Descriptive and inferential statistical analysis was performed using IBM SPSS Statistics version 28.0.1.0. A total of 34 consecutive patients underwent 38 NATs at our institution. Surgery indications were complex renovascular conditions in 35 cases (92.1%), of which 24 had renal artery aneurysms, and ureteral injuries in 3 cases (7.9%). Thirty-four kidneys (89.5%) were retrieved through a laparoscopic approach. No significant difference was observed between post- and pre-operative creatinine levels (0.81 vs. 0.72, = 0.303). Early high-grade complications developed in 12 procedures (31.6%). Median cold ischemia time was significantly longer in patients who developed complications (163.0 vs. 115.0, = 0.010). The median hospital stay was 10 days (8-13). The median follow-up was 51.5 months. NAT emerges as a successful therapeutic strategy for a highly select group of patients dealing with intricate ureteral lesions and kidney vascular abnormalities, demonstrating positive outcomes that endure in the long term.
