The aim of this study is to manage the calyceal diverticular (CD) stone, several treatment options were applied but it is still a challenging condition of endourology. In this retrospective study, we aim to report the results of our patients with CD stones treated with retrograde flexible nephrolithotripsy (RFNL). A total of 47 patients (55 procedures) who underwent RFNL by a single surgeon for CD stones from January 2004 to March 2013 were evaluated retrospectively. The demographic properties and initial complaints of those patients have been recorded along with their comorbidities and previous history of stone management. Moreover, the size and number of the stones, the duration of the surgery, fluoroscopy time, stone-free rate (SFR) and postoperative complications of the patients have been evaluated. The mean age was 41.8 years (range 16-71). Of the study population, 31 (65.9 %) were male. Mean stone size was 21.1 (7-52) mm whereas in 3 (6.4 %) of the cases the stones could not be reached. Mean duration of the surgery was 92.8 (57-163) min whereas mean fluoroscopy time was 35.9 (14-103) s. After 3 months of follow-up period, the SFR was 85.1 %. No major complications occurred. RFNL with holmium laser and nitinol basket catheter application is a feasible and successful procedure in the management of CD stones. With its high success rates, low incidence of complications and minimal morbidity when compared with other treatment options, RFNL has the potential of becoming the preferred treatment option in the minimally invasive management of patients with CD stones.
