Summary
Extra-anatomic placement of double-J (JJ) stents during antegrade insertion is a rare complication. Identifying risk factors for ureteric perforation is crucial for preventing this issue.
Area of Science:
- Interventional Radiology
- Urology
- Nephrology
Background:
- Double-J (JJ) stent insertion is common for urinary tract drainage.
- Complications include migration, encrustation, and fracture.
- Extra-anatomic placement is a rare antegrade JJ stent complication.
Purpose of the Study:
- To audit antegrade JJ stent insertions.
- To identify complications, specifically extra-anatomic placement.
- To determine risk factors for ureteric perforation.
Main Methods:
- Retrospective audit of 165 antegrade JJ stent insertions.
- Procedures performed by a single interventional radiologist.
- Analysis of complications and risk factors.
Main Results:
- Five (3%) patients experienced silent ureteric perforation and extra-anatomic stent placement.
- Complications included retroperitoneal abscesses, pelvic urinoma, ureterorectal, and ureterovaginal fistulas.
- Risk factors for perforation include prior pelvic malignancy, surgery, radiation, and ureteric manipulation.
Conclusions:
- Antegrade JJ stenting carries risks, including infrequent extra-anatomic placement.
- Diagnosis requires a high index of suspicion.
- Considering risk factors can help prevent ureteric perforation during stent insertion.

01:26Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
