168 double J (pigtail) ureteric catheter insertions: a retrospective review

Abstract

The medical records of 116 patients who had 168 ureteric double J (pigtail) catheters inserted over a 6-year period between 1981 and 1987 were reviewed. Eighty-five patients had pigtails inserted for benign conditions and 31 for malignant disease. The pigtail catheters were inserted cystoscopically in 88 patients, percutaneously in 7 patients and by open surgery in 21 patients. Of 168 pigtail catheters used, 147 were soft (silicone, multilength) and 21 hard (polyurethane). No mortality was attributable to the use of these catheters but certain complications were commonly encountered. Loin discomfort occurred after 32 (19%) insertions; 27 of 147 (18%) soft catheters and 5 of 21 (24%) hard catheters. Trigonal irritation, confirmed cystoscopically was reported in 26 of 147 (18%) insertions of soft catheters and in 6 of the 21 (29%) with hard catheters (chi 2, P = 0.37). Urinary tract infection (confirmed by urine microscopy and culture) occurred after 46 (31%) soft catheter insertions and after 13 of 21 (61%) hard catheter insertions (chi 2 test, P = 0.01). Stent migration occurred in five patients and obstruction in two. Pigtail catheters are safe ureteric stents which are easy to insert and their use is supported by this study. The complications of associated infection, trigonal irritation and loin discomfort are relatively common and still occur even with soft catheters. Careful monitoring of all patients with pigtail catheters in position is recommended.
