Retroperitoneal laparoscopic nephrectomy for nonfunctioning kidney

Objective To investigate the clinical application value of retroperitoneal laparoscopic nephrectomy for nonfunctioning kidney.Methods Fifty-four cases of retroperitoneal laparoscopic nephrectomy for nonfunctioning kidney were reviewed,including 9 cases with nonfunctioning tuberculosis pyonephrosis,18 cases with infection nonfunctioning pyonephrosis and 27 cases of nonfunctioning hydronephrosis.Fifty-four cases were received retroperitoneal laparoscopic nephrectomy,tuberculous and infection pyonephrosis underwent laparoscopic resection surrounding adipose capsule,nonfunctioning hydronephrosis underwent laparoscopic resection by pumping water to increase the peritoneal space.Results The operation of 54 cases were perfomed successfully.None of the patient required conversion to open surgery.During the surgery,1 case showed mild extravasation of cheese-like pus induced by laceration of the kidney capsule;2 cases had injuried on the peritoneum.The mean operation time was 125 (95-230) min,the mean blood loss was 84 (50-420) ml.All patients showed primary healing of the wound,the patients were discharged from the hospital in 6 to 11 d (mean 7.5 d).After followed up for 5-27 months,none of them had long-term complication.Conclusions Retroperitoneal laparscopic nephrectomy for nonfunctioning kidney has advantages of minimal invasion,less blood loss and quicker recovery,so it is a fairly safe and effective procedure for nonfunctioning kidney.
