Retroperitoneal laparoscopic nephropexy:a report of 8 cases / 第二军医大学学报

ABSTRACT

Objective:To study the indicators and operative method of retroperitoneal laparoscopic nephropexy.Methods: From August2001to June2003,8patients with nephroptosis underwent retroperitoneal laparospic nephropexy.All cases were women with an average age of34years(range26-45years).Five cases involved the right kidney,2on the left and1on the both.The presurgical symptoms included constant and recurring pain in8cases,upper urinary infections in6,hematuria in 5,upper tract obstruction in4.A retroperitoneoscopic procedure was performed after positioning the patient in the flank posi-tion.The decisive part was complete exposure exposure within Gerota'fascia to mobilize potential adhesions or the colon,espe-cially to pull inferior blood vessel of the kidney.Nephropexy was performed between the fibrous capsule of the lower pole of the kidney and the dissected psosa muscle using3sutures placed by intracorporeal or extracorporeal technique.Results:The mean operative time was125min(range115-240min);the mean post-operative hospital stay was9d,and the mean bedrest time was7d.During a mean follow-up of12months(range3-20months),1patient complained of recurrent pain,and there was1hematuria.No patient had further episodes of pyelonephritis or upper tract obstruction.IVP revealed kidneys in the af-fected part were in the normal region and greatly improved.Conclusion:Retroperitoneal laparoscopic nephropexy has less trauma,less post-operative discomfort and quicker recovery.It should be considered as the first choice for nephroptosis.[
