Abstract:
ObjectiveTo investigate the surgical management of left renal vein entrapment syndrome.MethodsEight cases with left renal vein entrapment syndrome (5 males and 3 female ; mean age 26 years) with history of gross hematuria for 3 to 46 months were reviewed.Doppler ultrasound reports suggested compression of the left renal vein at mesenteric angle in all cases.And the dilated segment of the left vein was three-fold than the stricture segment in diameter.CT scan showed the abnormal angle between aorta and superior mesentery artery in all cases.Bleeding from the left ureteral orifice was detected by cystoscopy in 6 cases.We treated 8 patients by extravascular stent immobilization with laparoscope.ResultsThe operation was successful in the 8 cases without surgical complications.The average operation time was 63 min.The average blood loss was 14 ml,and the average hospital stay after operation was 6 days.Follow-up of 3 -20 months,there was no hematuria relapse since been relieved in 7 cases,one case remained microscopic hematuria.Color Doppler ultrasound examination in all 8 cases showed the narrowest inner diameter of left renal vein was 7.4 mm (6.5 - 8.7 mm),the blood flow was smooth.The angle between abdominal aorta and superior mesenteric artery become normal.Conclusions Laparoscopic left renal vein extravascular stenting could be a new surgical method to treat left renal vein entrapment syndrome.The method of putting artificial blood vessel around renal vein is simple,safe and effective.
