Abstract
Background: Bladder catheterization is one of the most frequent procedures in Urology, but it is not exempt from complications.
 Relevance: Unintentional Foley catheter placement in the ureter is a rare occurrence that can produce serious complications. Few cases are described in the literature.
 Case report: We present herein two cases of inadvertent Foley catheter balloon inflation in the ureter. Case 1: an 85-year-old-patient with an indwelling Foley catheter was admitted to our emergency department due to abdominal pain in the hypogastrium, dysuria, and diagnosis of septic shock from extended-spectrum beta-lactamase-producing Escherichia coli. Case 2: a 75-year-old patient underwent transurethral resection of the bladder and presented with persistent hematuria and abdominal pain in the postoperative period.
 Conclusion: Unintentional urinary catheter placement in the ureter is an unusual complication and a diagnostic challenge that should be suspected in the presence of abdominal pain after bladder catheterization.
Highlights
Bladder catheterization is one of the most frequent procedures in Urology, but it is not exempt from complications
Either with a urethral catheter or a supra-pubic catheter, is one of the most common clinical procedures performed in Urology
Alternatives to placing an indwelling catheter should first be considered, making it a last resort when other options have failed or proved to be insufficient.[2]. Inadvertent placement of the urinary catheter in the ureter is a rare complication that can lead to serious complications, such as ureteric obstruction with hydronephrosis, ureteric injury, or even ureteric rupture.[3]. We present two cases of unintentional Foley catheter balloon inflation in the ureter
Summary
Either with a urethral catheter or a supra-pubic catheter, is one of the most common clinical procedures performed in Urology It is not exempt from complications.[1] An indwelling catheter should only be placed when it is clearly indicated and should not be retained longer than necessary. A 75-year-old patient had a past medical history of high blood pressure, atrial fibrillation, mitral insufficiency, chronic obstructive pulmonary disease, and T1GII urothelial bladder carcinoma and was admitted to our department due to hematuria and anemia. Abdominal and pelvic CT identified a Foley catheter at the right ureter (Images 3 and 4) It was removed and replaced with no incidences and the patient’s postoperative progression was good
