title: [The urological complications of contraception using intrauterine coils].
abstract: Being a foreign body, intrauterine coil causes decubitus and inflammation of the adjacent tissues. Long-term carriage of the coil may give rise to endometritis, myometritis, parametritis, salpingo-oophoritis, tubo-ovarian inflammatory infiltrates. These infiltrates invade retroperitoneal pelvic fat and may obstruct pelvic ureters. Ureteral obstruction may bring about ureterohydronephrosis, pyelonephritis and renal calculi. The coil may be also responsible for chronic pyelonephritis. The authors have treated 64 females aged 18-45 years with urological complications due to intrauterine coils which stayed from 6 months to 14 years. 34 of them presented with attack of acute pyelonephritis, 29 with renal colic and acute pyelonephritis, 26 with renal calculi. To arrest renal colic and attack of acute pyelonephritis ureteral catheterization and renal pelvis drain were performed in 31 patients. One patient has undergone ureterolithotomy. 8 patients rejected removal of the coil and had recurrent renal colics and acute pyelonephritis attacks. Removal of the coil arrested pyelonephritis and lithogenesis in the kidney. In one case of coil removal there was injury to the uterine cervix and urinary bladder eventuating in vesicovaginal fistula.
