Comparison of PCNL under spinal versus general anaesthesia

There are several advantages of performing percutaneous nephrolithotomy (PCNL) under spinal anaesthesia including lower cost, reduced adverse effects and less tracheal tube displacement. Another advantage is that the patient remains awake throughout making positioning easier and reducing the risk of...

Thermal ablative techniques for small renal masses

They were first described by Rayer in Traitements des maladies des reins [1]. Calculi occur in approximately 9.5% to...

Cryotherapy for small renal masses: better than surveillance?

Endoscopic management of upper tract urothelial carcinoma
