A half of 18 ureters recovered from the operation described in a previous paper showed hydronephrosis.
From the diameter of each ureter in the parts proximal and distal to the operational wound, the cases of hydronephrosis were classified into two groups, mild one (5 cases) and severe (4 cases).
The rate of peristalsis passing over from the proximal part to the distal part along the ureter was analyzed by the uretero-myogram: In the group of non-hydronephrosis, it was 74.2% to the mean value (52 to 100%). In the mild case, it was 37.9% (28.5 to 48.5%). In the severe cases, it was 6.1% (0 to 13.2%).
From the above results, it was suggested that, if the passing over rate of peristalsis did not reach 50%, hydronephrosis may develop.
