Serum total renin after tubal sterilization.

ABSTRACT

The effect of laparoscopic tubal sterilization by Hulka or Filshie clips on serum total renin levels was evaluated in 33 healthy, regularly menstruating women. Serum total renin levels were measured in the follicular (days 3 to 7) and in the luteal (days 20 to 24) phase during the cycle immediately preceeding the sterilization and 12 months after the procedure. The total renin secreted did not change after the sterilization. The follicular phase levels were lower (160 +/- 113 and 170 +/- 93 ng/l, respectively) than luteal phase levels (230 +/- 124 and 228 +/- 83 ng/l, respectively) in both cycles studied (p=0.0001 for both). The length of the menstrual cycle was not affected, either. Laparoscopic tubal sterilization caused no measurable changes in total renin secretion during one year follow-up.
