Abstract

This rare venous congenital anomaly has been diagnosed preoperatively in a 24-year-old female with complaints of the right flank and low back pain, and urinary frequency. In the I. V. P. the dilated upper right ureter forms a reversed "J" appearance. The right R.G.P. shows the "S"-shaped course of the ureter. The vena cavogram discloses crossing with the right R. G. P. at L3-4 intervertebral space level. 2.5cm. of strictured, postcaval segment of ureter is excised and end-to-end oblique anastomosis is done over splinting ureteral catheter. 4 months after the operation, the I. V. P. shows marked improvement of hydronephrosis and satisfactory drainage of urine compared with the preoperative films.
