Retrocaval ureter is a relatively rare anomaly where ureteric obstruction may occur as a result of ureter passes behind the inferior vena cava (IVC), hence, compressing it between the IVC and the vertebrae. We report 2 cases of retrocaval ureter with different presentations. One patient was managed surgically with minimally invasive approach and the other was managed conservatively.

Retrocaval ureter is a rare congenital anomaly of the urogenital organ originating from the venous maldevelopment. To our knowledge, retrocaval ureter with contralateral renal agenesis has not been reported in Korea. Recently, we experienced a case of retrocaval ureter with contralateral renal agenesis, and obtained a good result following ureteral resection with end-to-end anastomosis of the ureter.

Retrocaval ureter is a rare congenital anomaly and its embryologic error is probably one of the vena cava rather than the ureter. Since 1893, when Hocbstetter first described this condition, about 200 cases have been reported. Herein we added a case of retrocaval ureter in 26 years old man.

The operative technic for the correction of hydronephrosis due to obstruction at ureteropelvic junction has been discussed. There are two different types of technics in pyeloplasty ; 1st. nondismembered pyeloplasty molds and restructures the obstructed ureteropelvic junction without completely dismembering it and 2nd. dismembered pyeloplasty interrupts the continuity of the transport system of the obstructed ureteropelvic junction. Since Andereon-Hynes reported the technics which belongs to dismembered pyeloplasty for retrocaval ureter in 1949, many articles with satisfactory result have been published. We report Anderson-Hynes pyeloplasty for hydronephrosis secondary to obstruction of the ureteropelvic Junction in 7 cases. Advantages of Anderson-Hynes pyeloplasty are as follows. 1. Complete excision of the obstructive segment. 2. Reduction of the dead space. 3. Excision of a good part of the sick pelvis. 4. Activation of latent pacemaker P cells.

Retrocaval ureter is a rare venous congenital anomaly. We experienced a case of this anomaly, which combined with benign testicular tumor in 21 year old. man. I.V.P, vena cavogram and abdominal C.T were performed. Abdominal C.T was a precise and non-invasive method in the confirming of this anomaly, replacing the vena cavogram, if there remained the moderate degree of Rt. renal function. Now, we introduce the finding of abdominal C.T. in retrocaval ureter.

Post-caval or retrocaval ureter is a congenital anomaly of the vascular system. This anomaly almost. always involve the rt. ureter and occurs more frequently in male We have reported a 36 years male of rt. postcaval ureter that was resulted marked hydronephrosis due to compression of rt. ureter by vena cava. Three months after the operation, excretory urogram showed previous caliectasis and pyelectasis were moderately reduced and previous dislocated ureteral course was corrected.

Clinical and radiographic findings of four patients with retrocaval ureter are presented. An IVP and a retrograde pyelogram usually delineate a retrocaval ureter and inferior venacavogram is helpful in a doubtful case. Division of the renal pelvis with transposition and renastomosis is a preferable from of treatment although segmental resection of the ureter with ruetero-ureteral anastomosis is indicated at times.

This rare venous congenital anomaly has been diagnosed preoperatively in a 35-year-old female with complaint of the right flank pain. Herein a case of retrocaval ureter is presented with brief review of literatures.

Retrocaval ureter or circumcaval ureter is a congenital anomaly of vascular system commonly causing ureteric obstruction. We present a case of right retrocaval ureter with right renal stone in a 42 year old man and a case with right flank dull pain and hypertension in 40 year old female. They were treated with ureteral end to end anastomosis with double-J stent.
