Y1 - 2020 N1 - T2 - Smith & Tanagho's General Urology, 19e AB - Endoscopic procedures in the kidney rely on two primary approaches: retrograde and antegrade instrumentation of the upper urinary tract. The retrograde approach utilizes ureterorenoscopy to traverse the urethra and ureter, while antegrade instrumentation requires a percutaneous puncture directly into the kidney. Both approaches must respect the intrarenal anatomy just as in open renal surgery, and imaging is required for safety.
