Early experience with percutaneous radiofrequency ablation of small solid renal masses.

Objective: Incidental small renal-cell masses are often seen in elderly patients with significant comorbidity who are unfit to undergo major surgery. This study was conducted to determine the safety and efficacy of percutaneous imaging-guided radiofrequency ablation in the management of small solid renal masses, almost all of which are renal cell cancers.

Conclusion: Early experience suggests that radiofrequency ablation is a safe, well-tolerated, and minimally invasive therapy for patients with solid renal masses.

The role of Acucise endopyelotomy in the treatment of ureteropelvic junction obstruction.

Objective: Open surgical pyeloplasty has been the gold standard for the correction of ureteropelvic junction obstruction (UPJO). Endourological management of UPJO has gained increased acceptance, with reported success rates of 57-87%. It has been suggested that Acucise endopyelotomy (AE) should be the procedure of choice for patients with UPJO.
