AI Article Synopsis
- The study highlights the effectiveness of antegrade endoscopic examinations for assessing upper urinary tract issues in patients with an orthotopic neobladder.
- It details the procedures for percutaneous antegrade ureteroscopy and discusses how treatment decisions for urothelial tumors are made based on biopsy results.
- The findings suggest that endoscopic evaluation is safer and more informative than traditional methods like urine tests and imaging, enabling better treatment planning based on tumor characteristics.
Article Abstract
Objectives: To demonstrate the usefulness of antegrade endoscopical examination in the evaluation of the upper urinary tract pathology in patients with orthotopic neobladder.
Methods/results: We present the technique of percutaneous antegrade ureteroscopy and the indications for treatment of the upper urinary tract urothelial tumor (radical or conservative) depending on multiple pyelo-calyceal biopsies and tumor lesions.
Conclusions: Endoscopical evaluation of the upper urinary tract in patients with orthotopic neobladder offers safer information than urine analysis, urine cytology, and the various radiological tests. The difficulty for retrograde examination is on the identification of the ureteral neomeatus, so that in case of failure, antegrade percutaneous approach allows complete ureteral and pyelocalyceal examination and biopsies thanks to the development of flexible endoscopes. The information supplied by these endoscopical examinations of upper urinary tract urothelial tumors (grade, stage, multifocality) allows the choice of radical or conservative (open surgery or endoscopical) treatment.
