Abstract:
Objective To discuss the clinical features and treatment of ureteral obstruction resulted from vena genitalis compression.Methods 2 cases of hydronephrosis resulted from vena genitalis compression were discussed retrospectively,and relevant literatures were reviewed.Both of the 2 patients presenting with mild loin pain,and imaging studies showed hydronephrosis.One patients presenting with left hydronephrosis,and the other showed bilateral hydronephrosis.Imaging study showed ureter obstruction at L3-L4 level.Laparoscopic surgery found vena genitalis crossing and compressing the upper part of the ureter,resulted the upper ureter and pelvis dilation.Laparoscopic excision of vena genitalis were performed on these two cases.Results These patients'symptoms were relieved and hydronephrosis alleviated evidently 3 month after surgery in follow-up.Conclusions Hydronephrosis resulted from vena genitalis compression is a rare clinical manifestation.Classical imaging presents with ureter obstruction at L3-L5 level,at which the vena genitalis crossing the musculi psoas major.Ureter migrates outwards and the upper ureter and pelvis dilate.Pre-operative diagnosis is difficulty,but laparoscopic resection of the vena genitalis to relieve the obstruction of the ureter is recommended.
