Summary

in this study we are going to evaluate the efficacy of intra-ureteric aminophylline instillation in facilitating ureteric access sheath placement prior to flexible ureteroscopy in reducing ureteric injury rates.

Conditions

  • Stones, Kidney
  • Ureteric Injury

Interventions

DRUG

Usage of Aminophylline prior to ureteric dilatation in Flexible uretroscopy

Intraureteric aminophylline installation prior to ureteric dilatation

DEVICE

Sequential teflon dilator usage prior to ureteric access sheath placement in flexible uretroscopy

traditional ureteral dilators will be used. We will start by ureteral dilator 6 fr and gradually increase the size up to 12 Fr

OTHER

Aminophylline instillation and Ureteral dilators together

Aminophylline will be instilled as in group (A) then followed by traditional ureteral dilatation as in group (B) prior to placing the ureteric access sheath
