摘要
Acute hemorrhage during percutaneous surgery on the pelviureteric junction obstruction has been estimated to be 2-3%. Following the experience of peroperative bleeding from a vascular variation, the authors discuss the arterial anomalies bf the renal pedicle which may carry the risk of hemorrhage during percutaneous surgery in this region. Arteries in front of or behind the renal pelvis are the cause of ureteropelvic function obstruction in 15-52% of cases and because of their close relationship with the upper urinary tract can complicate the procedure of endopyelotomy. Endourological techniques are inadequate for avoiding the risk of vascular damage during the necessary maneuvers. Inferior polar arteries occur in 9% of the population and their different courses are described. They are not always responsible for the vascular obstruction in the pelviureteric syndrome, and it is the exact determination of this responsibility that makes imaging essential. Arteriography performed in our case allowed embolisation of the damaged inferior polar artery and also showed the anomalous origin of the testicular artery from this polar artery this appears to be only the second description of this anomaly. This variation is discussed in a review of the literature. In fact the testicular artery has a high or aberrant origin in 20% of cases; in 5-6% of these the origin is from a main or supernumerary renal artery. Origin from an inferior polar artery is exceptional.
