Objective: Describe our initial experience in the treatment of renal lithiasis with extracorporeal lithotripsy controlled by simultaneous flexible ureterorenoscopy and combined with holmium laser lithotripsy.
Material and methods: We performed this novel technique in a previously selected patient with left renal lithiasis, two in the superior calix, two in the medium calix and two in the inferior calix, the biggest of which was placed in medium calix and was 6mm long. We proceeded to an extracorporeal shock wave lithotripsy and a simultaneous flexible ureterorenoscopy for better controlling the fragmentation of the lithiasis with the use of a holmium laser. In the immediate post-operative, an ultrasound was performed and, one month later, a computerized tomography (CT) was done.
Results: The complete fragmentation of all the lithiasis was obtained and a double-J catheter was placed. After the assessment of the absence of stone fragments by CT the catheter was removed. No intra-operative or post-operative complications were described.
Conclusions: The technique described is novel, safe and reproducible. The good result obtained through this combined technique increases our interest in continuing with its application and consider it as an option for the treatment of renal lithiasis in our patients.
