Summary
Flexible ureteropyeloscopy accurately diagnosed all upper urinary tract filling defects when other methods failed. This endoscopic approach also enabled therapeutic intervention with minimal patient morbidity.
Area of Science:
- Urology
- Endourology
- Diagnostic Imaging
Background:
- Upper urinary tract filling defects present diagnostic challenges.
- Conventional imaging like CT and ultrasound may not provide conclusive diagnoses.
- Urinary cytology and brush biopsies can be limited in efficacy.
Purpose of the Study:
- To evaluate the diagnostic and therapeutic utility of flexible ureteropyeloscopy for upper urinary tract filling defects.
- To assess the safety and efficacy of this endoscopic technique.
Main Methods:
- Flexible ureteropyeloscopy was performed on 62 patients with undiagnosed upper urinary tract filling defects.
- Procedures included direct visualization and tissue sampling (biopsy) of lesions.
- Therapeutic interventions were performed when indicated.
Main Results:
- Flexible ureteropyeloscopy provided a definitive diagnosis in all 62 patients.
- Therapeutic intervention was successfully performed in 19 patients.
- No significant morbidity was associated with the procedures.
Conclusions:
- Flexible ureteropyeloscopy is a highly effective diagnostic tool for upper urinary tract lesions.
- It offers a safe and valuable option for both diagnosis and treatment.
- Routine inclusion in evaluation is recommended, except for clear cases of stones.
