Brief summary

Up-to-date, urology guidelines introduce safety guidewire (SGW) as an integral tool in ureteroscopy and recommended its routine use. However, the necessity of SGW placement in endourological procedures lack evidence and is being suggested as an expert opinion. Present study aimed to evaluate the use of SGW placement and its necessity in treatment of ureteral stones with semi-rigid ureteroscopy (s-URS). For this purpose patients with ureteral stones are being stratified according to ureteral stone location and prospectively randomized into two groups' according to SGW usage or not in s-URS. Ureteroscopy and litotripsy is being done with a semi-rigid ureteroscope of 6.4/7.8 Fr (Olympus) and laser. Chi-square and student t-test were used for comparing data.

Interventions

PROCEDURESemirigid Ureteroscopy (URS) With Guide Wire

Semirigid URS is the operations used for ureteral stone disease. In routine practice it is most commonly done with the use of a guide wire. It is conducted with ureteroscope and stone is disintegrated most commonly with lasers.

DEVICESemirigid Ureteroscopy (URS) Without Guide Wire

Semirigid URS is the operations used for ureteral stone disease . It is conducted with ureteroscope and stone is disintegrated most commonly with lasers.
