Results of laparoscopic retroperitoneal nephrectomy for benign nonfunction kidneys at Ninh Binh General Hospital

Introduction: Evaluating the result of laparoscopic retroperitoneal nephrectomy for benign nonfunctioning pathology at Ninh Binh General Hospital. Materials and Methods: 20 patients underwent laparoscopic nephrectomy surgery from 08/2016 - 03/2020 at Ninh Binh General Hospital, research with descriptive and prospective method. Results: The average operating time is 100,25 ± 22 minutes (80 - 180 minutes), the average amount of blood loss is 61,5 ± 26,6ml (30 - 100ml), the average amount of drain removal time is 2,5 ± 0,5 day (2 - 3 days), the time of taking analgesic is 3 days, the average amount of time for treatment in the hospital is 4,25 ± 1,1 days (3 - 6 days). During the operations, there is 1 case in which renal abscess and kidney inflammation occur. Therefore, it's difficult to carry out the umbilicus dissection and have to switch to kidney – removal open surgery. There are no adverse medical events or complications after the surgery. Conclusions: Laparoscopic retroperitoneal surgery in kidney removal due to nonfunctioning benign pathology is a safe and effective treatment method. Keywords: Laparoscopic nephrectomy, retroperitoneal laparoscopy.

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.
