Previously Oka, our director, published many papers on the indication of the kidney conservative surgery for clinical hydronephrosis. This is one of the supplemental studies. The results obtained were as follows: 1)The total number of hydronephrosis of degrees higher than C treated in our department during the past 21 years from 1947 to 1967 amounted 296 sides, of which 56 (19%) were markedly infected. 2)The percentage of marked infection for each degree of hydronephrosis was 13% in C, 22% in D, 37% in E and 50% in F. In short, it was found that the higher the degree of hydronephrosis, the more marked the infection. 3)Most of the high-degree hydronephrosis with marked infection were found to be caused by aquired diseases (83%). In the latter, there were calculi of the upper urinary tract in 65%. Strictures of UPJ and VUJ were identified in 80% of congenital cases. 4)As to the results of functional improvement of high-degree hydronephrosis with marked infection after conservative surgery, in congenital cases, considerable improvement was guaranteed. Only slight improvement, on the other hand, was noted in aquired cases. Especially, in those with renal calculi, the results were poor. 5)For the prevention of infection introduced by nephrostomized tube as well as for the treatment of infection before surgery, the author has devised an indwelling wash method of renal pelvis with excellent results. 6)Principally the advantage of kidney conservative surgery in high-degree hydronephrosis with marked infection is the same as that for not infected cases. In infected cases with renal calculi, a more cautious postoperative care is advisalle than in not infected cases.
