OBJECTIVES The present study investigates the outcome of Fowler-Stephens operation in prepubertal Wistar rats focused on microlithiasis and Leydig cell hyperplasia development. METHODS Thirty-eight (38) animals underwent laparoscopic Fowler-Stephens operation on the right testis (8 of them formed the control group) and 6 of them additional contra-lateral orchectomy. The testes were examined h...
OBJECTIVE To apply a semiquantitative method for analysis of technetium-99m-dimercaptosuccinic acid ((99m)Tc-DMSA) renal scintigraphy for monitoring the effect of extracorporeal piezoelectric lithotripsy (EPL) in patients with calyceal stones on regional kidney function and to check whether EPL had caused any deleterious effect on the target calyceal renal parenchymal function. PATIENTS AND M...
Comparison of the Effects Potassium Polycitrate with No Treatment on Microlithiasis Infants Referred to a Pediatric Nephrology Clinic
Pulmonary alveolar microlithiasis is a rare infiltrative pulmonary disease, in which intraalveolar accumulation of small stones (microliths) consisting of calcium phosphatite occurs. It is an autosomal recessive disorder. The disease occurs as a result of the disruption of type IIb sodium phosphate cotransporter in type II alveolar cells after the mutation of SLC34A2. Majority of patients are d...
Micropercutaneous nephrolithotomy is a safe and efficient technique for appropriate sized stones. It is performed through a 4.85 Fr all-seeing needle and stones are fragmented into dust, without the need for tract dilatation, unlike other percutaneous nephrolithotomy types. Even though micropercutaneous nephrolithotomy has many advantages, increase in intrapelvic pressure during surgery may cau...
Localization of Usher 1 proteins to the photoreceptor calyceal processes, which are absent from mice
The mechanisms underlying retinal dystrophy in Usher syndrome type I (USH1) remain unknown because mutant mice lacking any of the USH1 proteins-myosin VIIa, harmonin, cadherin-23, protocadherin-15, sans-do not display retinal degeneration. We found here that, in macaque photoreceptor cells, all USH1 proteins colocalized at membrane interfaces (i) between the inner and outer segments in rods and...
Objectives To compare elastography measurements in men with normal testicular tissue, testicular microlithiasis and testicular cancer. Methods A total of 248 consecutive patients were included. All men provided written informed consent. Testicular stiffness was assessed using shear wave elastography (SWE). Three SWE velocity measurements were assessed in each testicle. The patients were divid...
Pulmonary alveolar microlithiasis is a rare disease characterized by the deposition of calcium phosphate within the alveoli. We report the case of a 20-year-old man with a 6-week history of cough and shortness of breath on exertion. The chest radiograph demonstrated a bilateral symmetrical micronodular pattern. High-resolution computed tomography revealed bilateral diffuse fine nodular shadowin...
