Comparative StudyMinimally invasive percutaneous nephrolithotomy: an alternative to retrograde intrarenal surgery and shockwave lithotripsy.
There is a lack of studies comparing shock wave lithotripsy (SWL), retrograde intrarenal surgery (RIRS) and minimally invasive percutaneous nephrolithotomy (MIP) in renal stone treatment. This study compared treatment outcome, stone-free rate (SFR) and stone-free survival (SFS) with regard to stone size and localization. ⋯ RIRS and MIP were shown to have higher stone-free rates and SFS compared to SWL. The price for better outcome was higher, considering tolerable complication rates. Despite larger preoperative stone burden, MIP achieved high and long-term treatment success.

Comparative StudyComparison of retrograde intrarenal surgery, shockwave lithotripsy, and percutaneous nephrolithotomy for treatment of medium-sized radiolucent renal stones.
To compare the outcomes of shock wave lithotripsy (SWL), percutaneous nephrolithotomy (PNL), and retrograde intrarenal surgery (RIRS) for 10-20 mm radiolucent renal calculi by evaluating stone-free rates and associated complications. ⋯ For treatment of moderate-sized radiolucent renal stones, RIRS and PNL provide significantly higher success and lower retreatment rate compared with SWL. Although PNL is effective, its biggest drawback is its invasiveness. Blood loss, radiation exposure, hospital stay, and morbidities of PNL can be significantly reduced with RIRS technique.

Urinary NGAL and KIM-1: potential association with histopathologic features in patients with renal cell carcinoma.
NGAL and KIM-1 are suggested to play a key role in the carcinogenesis and progression of renal cell carcinoma. Attention is currently focused on the potential use of the urinary level of NGAL and KIM-1(uNGAL and uKIM-1, respectively) in making an early diagnosis, establishing a prognosis and determination of the histologic characteristics. ⋯ Combined analysis of uNGAL and uKIM-1 allowed high prediction rate of the histologic subtype of the radiographic-detected masses among cases with kidney cancer. These biomarkers may enable to select the proper therapeutic agents in cases with metastatic disease without the need of pretreatment biopsy.
