Abstract
To report the case of a 47-years-old woman with several small stones located inside a calyceal diverticulum of the right kidney and to highlight the importance of minimally invasive endourological treatment in these cases. Owing to the presence of diverticular calculi and clinical symptoms of recurrent infection, we decided to perform percutaneous nephrolithotomy (PNL). After Holmium-YAG laser calculi fragmentation and removal of all stone material, we fulgurated the diverticular lining and infundibulum with a resectoscope and a rollerball electrode. The patient is free of symptoms after 6 months follow-up. The disappearance of the calculi and diverticulum is confirmed with excretory urogram. Endourological approach for diverticular calculi, such as percutaneous nephrolithotomy (PNL), is a minimally invasive treatment with excellent results and low morbidity. Using this procedure we are able to perform stone removal and cavity fulguration. According to this, we think that endourological techniques, and specially PNL could be the first option for treatment in selected cases of this pathology.
