EVALUATION OUTCOMES OF THE LAPAROSCOPIC RETROPERITONEAL NEPHRECTOMY FOR BENIGN NONFUNCTIONING KIDNEYS

Purpose: To assess results of retroperitoneoscopy nephrectomy for benign non-function kidneys from June 2013 to June 2017 at Quang Tri General Hospital. Materials and Methods: The study comprised 43 patients who underwent retroperitoneoscopic nephrectomy during a 4 years period beginning from June 2013. Results: Mean age of surgery was 52.6 years (28-72 years). 23 males and 20 females. 25 patients underwent left nephrectomy; 18 underwent right nephrectomy. Retroperitoneoscopic nephrectomy were completed successfully in 38 patients (88.4%). There was 5 patients required conversion to open surgery (11.6%), all cases by poor progression. The mean operating time was 112.7 minutes (range 70 to 210), mean blood loss was 45.7 ml (range 15 to 170 ml), and mean post-operation hospital stay was 4.3 days (range 3 to 9). A total of 21.1% complications (8/38 cases), no severe complications occurred. No re-intervention was needed. No case was mortality. The indications for surgery included hydronephrosis in 19/38 cases (50.0%), atrophic kidney in 13/38 cases (34.2%) and multicystic kidney in 6/38 cases (15.8%). Conclusions: Retroperitoneoscopic nephrectomy can be performed safely and successfully with obvious advantages for benign nonfunctioning kidneys regardless of the etiology or pathogenesis.
