[Ureterorenoscopy as a diagnostic procedure in the upper urinary tract]

Area of Science:

• Urology
• Endourology

Context:

• Ureteropyeloscopy (UP) is an established endoscopic procedure.
• The study covers a significant period of UP development and application from 1984 to 1991.

Purpose:

• To evaluate the utility of ureteropyeloscopy in diagnosing and treating upper urinary tract conditions.
• To assess the role of different ureteropyeloscope designs in achieving complete visualization.

Summary:

• A total of 1635 ureteropyeloscopies were performed, with 180 dedicated to diagnostic purposes.
• Rigid ureteropyeloscopes provide access to the ureter and upper calix.
• Actively deflectable instruments are essential for visualizing the middle and lower calix.

Impact:

• Highlights the importance of specialized instrumentation for comprehensive upper urinary tract examination.
• Contributes to understanding the evolution and application of ureteropyeloscopy in clinical practice.
