TI  - Single session vs two sessions of flexible ureterosopy (FURS) for dusting of renal pelvic stones 2-3 cm in diameter: Does stone size or hardness play a role in number of sessions to be applied?"
AB  - Objective: To evaluate the stone hardness in predicting the need for single or two sessions of retrograde intrarenalsurgery (RIRS) for renal pelvis stones of 2-3 cm in size.Material and methods: Ninety-six patients (64 male and 32 female) with only renal stones (2.5±0.3 cm)underwent RIRS using flexible 7.5 Fr ureteroscope (FURS). The stone hardness was evaluated by preoperativenon-contrast computed tomography (NCCT). The patients were divided into two groups based on stonehardness: Group I (n=54) (hard stones - Hounsfield Unit (HU) >1000) and group II (n=42) (not hard stone - HU<1000). The stone- free rate, the operative time, any intra or postoperative complications and the need for secondsessions of RIRS were evaluated.Results: All stones were successfully accessed. Intraoperative complications were not reported. The initialstone- free rate was 40% in Group I and 95% in Group II after a single session (p=0.01). A second sessionFURS was needed in 32 cases of Group I (40%) where postoperative CT showed significant residual stonefragments of 6±2 mm, and stone-free rate up to 100 percent. On the contrary only 2 cases from Group IIunderwent second session FURS (p=0.01). The operative times were 75±15 minutes in Group I and 55±13minutes in Group II (p<0.01). Six patients (4 in group I and 2 in group II) had postoperative high- grade fever(Clavien Grade II).Conclusion: Stone hardness had a significant impact on the decision of performing single versus two sessionsof FURS for renal pelvic stones of 2-3 cm rather than the stone size alone.
