CONTEXT Ureteroscopically guided laser techniques are commonly used in the treatment of upper urinary tract transitional cell carcinoma (UUTT); however, there is an ongoing debate with regard to indication and management. OBJECTIVE To review the indication, feasibility, and treatment outcome of laser application for definitive endoscopic treatment of(More)
BACKGROUND In percutaneous nephrolithotomy (PNL), the best possible way to access the collecting system is still a matter of debate. There is little possibility of correcting a suboptimal access. OBJECTIVE To describe our initial experience using a micro-optical system through a specific puncture needle to confirm the quality of the chosen access prior to(More)
OBJECTIVE The purpose of this study is to assess the accuracy of dual energy CT (DECT) in the characterization of renal and ureteral stones. MATERIAL AND METHODS Twenty-four renal calculi of known variable composition were scanned on a dual-source CT scanner (Somatom Definition; Siemens Medical Solutions, Forchheim, Germany) in dual energy (DECT) mode.(More)
PURPOSE To our knowledge we report the first technical feasibility and safety study of 1-step percutaneous nephrolithotomy using the previously described 4.85Fr all-seeing needle (PolyDiagnost, Pfaffenhofen, Germany). We defined microperc as modified percutaneous nephrolithotomy in which renal access and percutaneous nephrolithotomy are done in 1 step using(More)
OBJECTIVE To prospectively evaluate health-related quality of life (HRQoL) and perioperative outcomes in patients with T1 and T2 renal cell carcinoma (RCC) after retroperitoneoscopic radical nephrectomy (RRN), open RN (ORN) or open nephron-sparing surgery (NSS). PATIENTS AND METHODS The data of 117 patients who had undergone RRN (36), ORN (37) or NSS (44)(More)
Percutaneous stone removal increasingly plays an important role among the different approaches of interventional stone therapy, particularly since the development of miniaturized instruments is resulting in lower morbidity for the patients. One major drawback of smaller instruments is the increased difficulty of stone retrieval after disintegration due to(More)
In addition, the system states whether the access tract is sealed after the procedure in case of totally tubeless interventions (t treatment). Each parameter is characterised by an acronym added to the term “PCNL” (see Table 2). For example, a PCNL in prone position with an access tract diameter of 16 FR using low-pressure continuous-flow irrigation without(More)
PURPOSE High dose local stereotactic radiosurgery was performed in select patients to improve local tumor control and overall survival. We report on patients with renal tumors treated with single fraction robotic stereotactic radiosurgery. MATERIALS AND METHODS A total of 40 patients with a median age of 64 years who had an indication for nephrectomy and(More)
The objectives of this study are to assess the efficacy and safety of retrograde ureteroscopic holmium laser lithotripsy for intrarenal calculi greater than 2 cm in diameter. A total of 24 patients with a stone burden >2 cm were treated with retrograde ureteroscopic laser lithotripsy. Primary study endpoints were number of treatments until the patient was(More)
Sexual dysfunctions (SD) are adverse effects of common drug therapies that have rarely been considered in investigations so far. Possibly it is barely known that many widespread and frequently prescribed medications and drug therapies can have significant impact on vascular and nerval processes as well as on endocrinologic and psychoneuroendocrinologic(More)
