Purpose With advances in technology, ureteroscopy is increasingly utilized for the management of urolithiasis. Previous studies have attempted to characterize the post-operative complication and readmission rates relative to the technical difficulty of the procedure. There is limited data exploring resident level of training and its effect on adverse outcomes in these cases. We review our experience with ureteroscopy to create a model to predict factors, including resident experience,that affect rates of post-operative complications Materials and Methods We reviewed ureteroscopies performed at our academic facility from January 2009 to December 2013...

Pyrrosiae Folium (PF) is a commonly used Chinese herb medicine originating from three Pyrrosia species for the treatment of urinary infection and urolithiasis. According to Chinese medicine practice, different specie origins led to some variations in the therapeutic effects of PF. To ensure the safety and efficacy of PF in clinical practice, it is necessary to establish a reliable and integrative method to distinguish PF occurring from the three species. In the present paper, a HPLC-DAD method was developed and applied to simultaneously analyze five major compounds in PF...

Congenital ureteropelvic junction obstruction (UPJO) is the most common cause of upper urinary tract obstruction in children. It is generally diagnosed in the routine work-up during antenatal period and is characterized by spontaneous recovery. It can be associated with urolithiasis; hence further investigation should be carried out. We report the case of a 15-year-old boy, who is known to have right UPJO, presented with right renal colic and discovered to have bilateral kidney stones. Further studies showed primary hyperparathyroidism and genetic analysis revealed a CDC73 mutation (initially HRPT2)...

We performed morphological analysis of the effect of the peptide complex from porcine kidneys on the course of experimental urolithiasis modeled in rats by treatment with 1% ethylene glycol solution (in drinking water) for 6 weeks. The peptide complex obtained by acetic acid extraction was administered in a dose of 15 mg. Administration of the peptide complex to animals with experimental kidney stone disease leads to 100% destruction of large and medium stones to the "dust" granularity.
