Purpose: 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.
Methods: This analysis included 482 first-time-treated patients in the period 2001-2007.
Purpose: Laparoscopic partial nephrectomy (LPN) is the treatment of choice for localized tumors in many centers. We aimed to evaluate differences in complication rates and outcome stratified by risk categories, depending on patient or tumor characteristics.
Methods: Eighty-one patients who underwent LPN for localized renal tumors between 2004 and 2007 were evaluated.
The development of new-generation flexible ureteroscopes has improved diagnostic and therapeutic endourological procedures. Despite technical improvement irrigation flow and quality of vision is often unsatisfactory. This study describes inter-manufactural differences in the latest available flexible ureteroscopes in terms of irrigation flow in correlation to different deflection angles and the use of 1.

Patients And Methods: In all, 45 patients with primary localized prostate cancer that underwent radical prostatectomy were included in the present study. Upon scoring of the pathological grade, expression and phosphorylation levels of PKB/Akt and relevant downstream targets were determined in tissue specimens by immunohistochemistry using specific antibodies against PTEN, PKB/Akt, its downstream targets, and the respective phosphorylated proteins.
