Purpose: To evaluate the outcome of endoscopic management of upper-tract transitional-cell carcinoma (TCC).
Patients And Methods: From March 1991 to March 2006, 40 patients with upper-tract TCC were treated by an endoscopic approach as the primary management: 37 (90.2%) by ureteroscopy and by percutaneous techniques or both approaches in 2 cases each (5%).
Objective: To evaluate the efficacy of a fourth-generation lithotripter, the Sonolith Vision (Technomed Medical Systems, Vaulx-en-Velin, France) for treating single previously untreated renal calculi, and to compare the results with the reference standard HM-3 (Dornier MedTech Europe GmbH, Wessling, Germany) in the same population originally studied by the USA Cooperative Study Group in 1986.
Patients And Methods: The Sonolith Vision uses an innovative electroconductive shock-wave generator with an elliptical reflector specially designed to give the maximum concentration of energy on the stone. We reviewed the treatment sessions from our prospectively maintained database of the first 1000 consecutive patients with urinary stone disease who were treated with the Sonolith Vision between September 2004 and March 2006.
Purpose Of Review: The management of ureteric colic has changed significantly over the past three decades,. Factors such as stone size, location, composition as well as patient and surgeon preference influence the management decision.
Recent Findings: Recent work has looked at the expansion of the role of medical therapy beyond symptomatic control to attempt to target some of the reversible factors in stone retention and thereby improve the likelihood of spontaneous stone expulsion.
