“…Miroğlu et al 16 reported that there was no important difference in ureter diameter at the proximal of the stone between patient groups with and without stone migration in their series. They emphasized that stone migration is more related to the distance between the stone and the U-P junction.…”

Objective: In our study, we aimed to evaluate the parameters that are effective in predicting the possibility of stone migration during ureteroscopic lithotripsy. Patients and method: We divided our patients two group whom we applied ureteroscopic lithotripsy. Patients who migrated stones during ureteroscopic manipulation to the 1st group, and the patients who did not migrate stones to the second group were included. We measured the proximal ureter diameters of the patients in both groups on their computed tomography. We compared these values statistically. In addition, we determined a cut-off value for the ureter diameter to predict the possibility of stone migration. Result: Especially, ureter diameters of patients with middle and lower ureter stones showed significant differences between groups. Also, stone sizes differed significantly between groups. Conclusion: We concluded that the possibility of stone migration is high in patients with a ureter diameter higher than 7.45 mm in the middle and lower ureteric stones. Also, we believe that stone diameter and the surgeon’s experience are effective factors in stone migration.

“…Ureteral stricture is a devastating complication of ESWL, which might be the result of an extreme reaction that occurs because of tissue damage from the shock waves. 14 One of the main questions of our study was: "Does the presence of pre-RIRS ESWL complicate the RIRS procedure?" The peroperative variables, such as operation time and peroperative complication rates, were similar between the groups.…”

“…Although these findings have been shown in the renal parenchyma and papilla, the ureteral wall might also be exposed to similar reactions after the ESWL treatment of ureteric stones.

The evolutional history of retrograde intrarenal surgery (RIRS) dates back to the 1970s, but the clinical usage of this technique has gained increasing popularity in the last two decades. 1 The functional developments of flexible ureteroscopes, lasers and ancillary equipment have led RIRS to become a significant surgical technique for the treatment of upper urinary system stones. 2 Because of these technological advancements, the guidelines for the treatment of urinary system stone disease have been frequently revised.Despite these technological advancements, extracorporeal shock wave lithotripsy (ESWL) still maintains its importance for the treatment of upper urinary system stones less than 2 cm. in diameter. Moreover, recent studies reporting the trends of urolithiasis treatment have shown a significant increase in the use of ureteroscopy compared with ESWL. [3][4][5] RIRS and ESWL are the two main treatments for proximal ureter stones. The European Association of Urology (EAU) guidelines recommend ureteroscopy as the firstline treatment for proximal ureter stones >10 mm and ureteroscopy or ESWL for proximal ureter stones <10 mm. 6 According to the

Efficacy and safety of the Accordion® stone-trapping device: in vitro results from an artificial ureterolithotripsy model

et al. 2009

One of the challenges of intracorporeal ureterolithotripsy is undesired stone migration. Stone-trapping devices have been designed to prevent this quite common phenomenon. These devices have to be effective in terms of ureteral obstruction and safe in terms of resistance to the action of commonly used lithotriptors. This work was conducted to evaluate the efficacy and safety of the recently approved Accordion stone-trapping device in vitro. In a rigid, submerged ureteral model with two different diameters (8 and 10 mm), artificial stones were positioned in direct contact with the engaged Accordion device. A defined number of pneumatic pulses of the LithoClast master at different performance levels was applied and the migration distance of the stone was measured after each single pulse. As a control, the same series was repeated without the stone-trapping device. Secondly, the Accordion device was exposed to a previously defined number of pneumatic or Ho:YAG-laser pulses, in direct contact with the lithotripsy probe, up to a total activation time of 2 min. At different time points, the device was controlled for damage and functionality. The mean stone migration distance without the Accordion device was between 39.2 and 52.8 mm and between 37.8 and 75.4 mm in the 8 and 10 mm tubes, respectively. In comparison, the stone or fragment travelling distance with the device was in the 0-2 mm range. This difference was highly significant. Both pneumatic and laser lithotriptor did not affect the functionality of the Accordion device. The Ho:YAG laser causes small perforations of the film without affecting the devices' stability. The Accordion device appears to be highly efficient and safe in vitro. Clinical trials will have to assess its value in endourological practice. Randomised comparative trials comparing different stone-trapping devices are needed.
