Rethinking the Limits of Flexible Ureteroscopy — An Interview with Prof. John D. Denstedt
As the prevalence of kidney stones continues to rise and complex stone disease becomes increasingly common, there is growing demand for minimally invasive, effective, and safe treatment strategies. Flexible ureteroscopy has become a cornerstone of upper urinary tract stone management; however, its role in treating large stone burdens, infection-related stones, and anatomically complex cases remains a subject of debate. Meanwhile, advances such as laser lithotripsy, single-use ureteroscopes, and suction-assisted access sheaths continue to expand treatment possibilities. Balancing maximal stone clearance with minimal complications remains one of the key challenges in modern endourology.
