OBJECTIVE The aim of this prospective study was to compare the resistive index (RI) values, which is a parameter of testicular parenchymal perfusion, in testicular microlithiasis (TM) cases and normal cases. MATERIALS AND METHODS 2179 volunteers, all healthy men (17-42 years of age) from the Annual Army Reserve Officer Training Corps training camp were included in the study. A screening scrot...

BACKGROUND The recurrent microlithiasis represents one of the most frequent clinical forms of lithiasis of the bile ducts. This affection is characterized by the presence of cholesterolic microgallstones on hepatic canaliculars, and belongs to a heterogeneous group of autosomal recessive liver disorders. Radiological diagnosis can be confirmed by analysis of MDR3 gene, coding a protein involved...

Calyceal diverticular stones are rare clinical entities without a clearly defined consensus on the treatment. Treatment indicationsinclude recurrent urinary tract infections, chronic pain and renal impairment. modality of surgical approach is usuallybased location calyceal diverticulum.A 23-year-old woman was presented with stone 16.5 mm. Her medical history revealed multiple tractinfections ca...

Large calyceal synapses are often regarded as simple relay points, built for high-fidelity and high-frequency synaptic transmission and a minimal requirement for synaptic plasticity, but this view is oversimplified. Calyceal synapses can exhibit surprising activity-dependent developmental plasticity. Here we compare basal synaptic transmission and activity-dependent plasticity at two stereotypi...

A nine and 13-year-old boy, previously diagnosed with 18q syndrome and an 11q deletion, respectively were diagnosed with testicular microlithiasis (TM). Both cases demonstrate that TM occurs in patients with various chromosomal abnormalities.
