BACKGROUND Many minimally invasive interventional techniques as well as expectant treatment exist for the management of lower ureteric calculi. This study was conducted to evaluate th efficacy of tamsulosin as an expulsive pharmacologic therapy for the treatment of distal uretern stone. METHODS This randomized control trial included 100 patients over 18 years of age wit stone Size > or = mm i...

Background: To introduce the new-generation super-minipercutaneous (SMP) nephrolithotomy system and describe its application in practice. Methods: We described the technique of SMP in the treatment of renal stones with an emphasis on the devices, indications, technique procedure, advantages, and results. Results: The new-generation SMP endoscopic system consists of an 8 F super-mini nephroscope...

PURPOSE Percutaneous nephrolithotomy effectively treats large volume renal calculi but relies on postoperative imaging to judge success. We evaluated the effectiveness of maximizing intraoperative imaging through combined high resolution fluoroscopy and flexible nephroscopy. MATERIALS AND METHODS Percutaneous nephrolithotomy was performed cooperatively with a radiologist in an interventional ...

Krull dimension measures the depth of the spectrum Spec(R) of a commutative ring R. Since Spec(R) is a spectral space, Krull dimension can be defined for spectral spaces. Utilizing Stone duality, it can also be defined for distributive lattices. For an arbitrary topological space, the notion of Krull dimension is less useful. Isbell [23] remedied this by introducing the concept of graduated dim...
