The Effect of Ureteral Anastomosis Upon Conduction of Peristaltic Waves: An Electro-Ureterographic Study

The Effect of Transureteroureterostomy upon Conduction of Peristaltic Waves

“…In the short-term study, peristalsis of Type I coming from the left upper ureter showed a percentage of 60; that is, 60 percent of the peristaltic waves coming from the left upper ureter were effectively conducted through the anastomosis , whereas, for those of Type III coming from the right upper ureter, the percentage of Type II was 100, i.e., all the peristaltic waves coming from the right upper ureter were obstructed at the anastomosed site. The same result was reported concerning a transected and an anastomosed ureter by Butcher and Sleator (1956) , Weinberg and Siebens (1958), and Caine and Hermann (1970). If the failure of peristalsis causes significant stasis, pressures at the anastomosed site would be markedly increased and eventually elevate the pressure in the `right' renal pelvis.…”

“…than during the preoperative level, reaching a normal level usually between the 5th and 6th hr following the operation. These tendencies have also been noted by Butcher and Sleator (1956), and Weinberg and Siebens (1958). Butcher and Sleator (1956), using an intraluminal electrode, observed that conduction velocity was slower in the ureters above the anastomosis than below it when a significant hydroureter was present.…”

“…These tendencies have also been noted by Butcher and Sleator (1956), and Weinberg and Siebens (1958). Butcher and Sleator (1956), using an intraluminal electrode, observed that conduction velocity was slower in the ureters above the anastomosis than below it when a significant hydroureter was present. We agree to their observation that both the frequency and velocity in the ureters above the anastomosis are increased, and that these tendencies appear to be induced by urine retention above the anastomosed site, the cause of which is a functional defect in the peristaltic conduction through the anastomosis.…”

Postoperative Recovery of Ureteral Peristalsis

“…The long incision transverse-sutured group showed the greatest inhibition of flow. Butcher and Sleator (1956) reported that the detachment of a part of the ureter from the retro-peritoneum causes suspension of the peristaltic movement in the detached part. Takakura (1960) also reported that after total ligation, half transsection and hard pinching of the ureter, more or less severe obstruction to the passage of peristaltic discharges occured, as observed electroureterographically.…”

“…In general, discharge function of the ureter, on which the surgery was carried out, has been studied by means of pyeloureterography, but there are only few reports on electroureterographic studies including those by Butcher and Sleator (1956) and Weinberg and Siebens (1958) who used canine ureters.…”
