“…Although the term 'clinically insignificant' has been applied to stone fragments of ≤ 4 mm, studies [16][17][18][19][20] have shown that 12-46% of such fragments can increase in size (over median follow-up periods of 23-40 months). Candau et al .…”

“…The sensitivity of the UHCT was almost 100% compared to 47.6% for KUB, 89.2% for linear tomography and 67.8% for US (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19). UHCT, despite its high sensitivity and specificity in stone detection, is not perfect.…”

“…The preoperative factors analyzed were stone diameter (mm), stone volume (mm 3 ), stone number, stone side (right or left), age, sex, height, bodyweight, BMI, presence of hydronephrosis (including partial hydronephrosis), presence of lower pole calculi, preoperative placement of ureteral stent and stone location (ureter stones, renal stones, or both). Stone volume was determined on 5 mm axial and 3.5 mm reconstructed coronal NCCT images, as described previously.…”

Objective: To investigate factors predicting spontaneous clearance of residual renal fragments after flexible ureteroscopy. Methods: Among 546 patients who underwent lithotripsy with flexible ureteroscopy, 81 had residual renal fragments, as determined by kidney-ureter-bladder films on postoperative day 1. The final outcome was determined at 3 months after the last flexible ureteroscopy session using non-contrast computed tomography. Patient characteristics and preoperative factors were analyzed using the unpaired t-test and 2 -test. Correlations between the possible predictive factors and the spontaneous clearance of residual renal fragments after flexible ureteroscopy were analyzed using a multivariate logistic regression model with backward selection. Results: Non-contrast computed tomography at postoperative month 3 showed that 33 cases (40.7%) had spontaneous clearance of residual renal fragments, whereas 48 (59.3%) showed non-clearance. Significant differences were found between these cases in terms of stone number, stone location, presence of lower pole calculi and preoperative stent placement. Multivariate assessment showed that stone number (P = 0.004), presence of lower pole calculi (P = 0.021) and presence of hydronephrosis (P = 0.024) were independent predictors of the spontaneous clearance of residual renal fragments after flexible ureteroscopy. Conclusions: Stone number, presence of lower pole calculi and presence of hydronephrosis are independent predictive factors of the spontaneous clearance of residual renal fragments after flexible ureteroscopy.
