Abstract

Background: Urinary catheterization is among the most frequently performed procedures in urology, commonly utilized for both diagnostic evaluation and therapeutic management. Catheter-related complications are common, but ureteric entry is rare and usually unilateral; bilateral obstruction has not been reported.
Case Presentation: A 17-year-old male was presented with neurofibromatosis type 1, recurrent spinal glioblastoma, and neurogenic bladder on long-term catheterization, who developed flank pain, nausea, vomiting, and rising creatinine. CT showed a suprapubic catheter in the right ureteric orifice and a Foley’s catheter blocking the left. Careful exchange of both catheters led to resolution of obstruction, normalization of renal function, and clinical recovery. The creatinine level went back to normal, and the patient was discharged with outpatient appointment and a new renal US.
Conclusion: This case emphasizes that patients with neurologic impairment and chronic catheter dependence are particularly at risk. Careful insertion techniques, confirmation of catheter position, and early imaging in those with unexplained renal dysfunction are essential to ensure timely diagnosis, prevent irreversible dam age, and improve patient outcomes.
