Eight cases of hydronephrosis due to aberrant vessels experienced during the past 5 years (from 1975 to 1980) were studied, comparing them with 12 cases of hydronephrosis caused by congenital stenosis in the ureteropelvic junction (p-u stricture).
There were no remarkable differences in clinical pictures between the studied cases and those in the literature, including age and sex distribution, together with chief and side complaints. However, when compared with the congenital P-U stricture cases, the incidence of pain attack was higher and the duration of illness was shorter.
It was found that the renal damage of the studied cases was milder than in the others through preoperative IVP studies. This fact indicates that the sudden onset of sharp pain brought about by excerbation effect of aberrant vessels shortened the durationn of illness in the studied cases. This might propose the necessity of the sophisticated venography study in addition to the conventional angiography whenever hydronephrosis due to aberrant vessels are suspected.
Current general understanding is the dismembered pyeloplasty with conservation of the vessels is the best way to treat the hydronephrosis due to P-U stricture. Our results were also in accordence with it.
