Iatrogenic Ureteral Obstruction With Ureteral Orifice Polyp Secondary to Foley Catheter Misplacement: A Case Report With Cystoscopic and Imaging Findings.

INTRODUCTION

Foley catheterization is a routine urologic procedure, yet complications may arise, particularly in patients with long-term indwelling catheters.

CASE PRESENTATION: We present a rare case of iatrogenic ureteral obstruction caused by inadvertent Foley catheter insertion into the right ureter in a 55-year-old male nursing home resident. The condition led to right-sided hydronephrosis and recurrent urinary tract infections. Diagnosis was established using computed tomography, which confirmed the catheter's entry into the ureter, and cystoscopy revealed polypoid lesions around the right ureteral orifice. After management with an antegrade Double-J stent, Foley catheter reinsertion, and antibiotic therapy, the patient's condition improved. Follow-up cystoscopy during hospitalization demonstrated a marked reduction in the size of the polypoid lesions, with the right ureteral orifice located within a cellule between two gate-like trabeculations.

CONCLUSION

This case highlights the importance of vigilance in long-term catheter management and imaging in recurrent urinary tract infections.
