In a sequential patient series, the hazards of peri-operative ureteral catheter implantation were assessed.
Patients who had a peri-operative ureteral catheter placed at a single institution in 2018 were included in the study. A retrospective evaluation was performed to analyze patient and procedure variables such as technique, perceived placement difficulties, operational details, and complications. The Clavien-Dindo technique was used to assess urologic problems within 30 days. The X2 test or Fisher’s exact tests were used for the statistical study of association.
There were 413 patients in all. Urologic problems occurred in 50/413 (12.1%) of the patients within 30 days. Clavien-Dindo grades I-II were represented by 43 people. About 6 were in the third grade. Five of six individuals developed oliguric, obstructive AKI. Just 1 patient experienced flank discomfort as a result of hydronephrosis. Two patients had a unilateral nephrostomy tube, a bilateral double-J stent, and a unilateral stent. One patient experienced a Grade V complication. They suffered from multi-system organ failure, including renal failure with hydronephrosis. All patients who needed re-intervention had bilateral peri-operative catheterization with a wire. Intraoperative placement difficulties were related to high-grade complications (P<.01). The retrospective, single-center research design is one of the study’s limitations.
The rate of acute complication after ureteral catheter implantation is 13%. In addition, post-operative ureteral blockage occurs in 1.7% of patients, necessitating surgery within 30 days. Future research is needed to identify patients more vulnerable to post-ureteral stent complications.
