Efficacy of Aspiration-Assisted Ureteral Access Sheath (ClearPETRA) in Retrograde Intrarenal Surgery.

In the renal intrarenal stone surgery (RIRS) procedure, ureteral access sheath (UAS) is still used in the majority of surgeries to both protect the flexible ureteroscope (FURS) and reduce intrarenal pressure. ClearPETRA is a new UAS that has an integrated aspiration port. We aimed to evaluate the clinical outcomes and effectiveness of Aspiration-Assisted UAS (ClearPETRA) in the RIRS procedure.

Can stone migration be predicted preoperatively in ureteroscopic lithotripsy?

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.

Comprehensive examination of haematological parameters of patients operated due to testicular torsion.

We aimed to investigate the pre-operative predictive role of haematological parameters in patients with testicular torsion. The medical records of patients operated between January 2016 and November 2018 were retrospectively analysed. The demographic characteristics and complete blood count of the patients were recorded.
