Abstract:
Objective To present the experience of diagnosis and treatment of 21 cases of retrocaval ureter. Methods 21 cases of retrocaval ureter were retrospectively analysed. Results The main clinical symptom was right waist pain in 20 cases,4 of them with typical renal colic.8 cases had gross hematuria and calculus in the renal pelvis.1 case was void of symptom.The diagnosis of the disease depended mainly on intravenous urography (IVU) and retrograde ureteropyelography (RGU).IVU and RGU showed a "S" shaped upper ureteral segment with dilatation. Ureteral replacement and ureteroplasty were carried out in 20 cases which have been followed up from 2 months to 28 years with an average of 13 years.The symptom disappeared in 19 cases,with hydronephrosis and hydroureter significantly reduced on IVU and ultrasonography.1 case underwent ureteral reanastomosis because of stenosis at anastomosis site. Conclusions In patients with hydronephrosis and hydroureterosis of upper segment on the right side,the possibility of retrocaval ureter should be considered.Intravenous urography and retrograde ureteropyelography are the main means of diagnosis.Ureteral replacement and ureteroplasty are the treatment of choice.
