Abstract:
Recent advances in techniques of imaging and ablation have led to the application of several minimally invasive modalities, such as radiofrequency ablation (RFA) with a success rate varying from 79 to 96% and a serious complication rate of 1 to 4% in the treatment of small renal tumors. The authors report on the case of a 67-year-old patient with a radiofrequency ablation complication, stenosis of the ureteropelvic junction in one kidney, and analyze the results of this modality for the treatment of renal tumors.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
