Pulmonary alveolar microlithiasis is a rare, inherited pulmonary disorder affecting young adults. Diagnosis and monitoring is important as it may progress to pulmonary fibrosis and respiratory failure. No effective treatment has been found to date.

OBJECTIVE To present the results of upper calyceal access during percutaneous nephrolithotripsy (PCNL) for stones in the lower calyx, as PCNL is considered the most effective minimally invasive surgery for managing lower calyceal stones, with percutaneous access either directly to the lower calyx or through an upper or middle calyx. PATIENTS AND METHODS The study included 76 patients with sin...

Case report from a 12-years old russian girl with pulmonary alveolar microlithiasis. The diagnosis was confirmed by histologic examination from biopsy specimen of the lung. The differential diagnosis and the histomorphology are discussed.

BACKGROUND There are limited studies about testicular microlithiasis (TML) and background information such as health, lifestyle, and socioeconomic status. PURPOSE To assess the prevalence of TML in relation to socioeconomic status and ethnicity. MATERIAL AND METHODS From a database of scrotal ultrasound examinations in a single institution, all men who underwent routine ultrasound examinati...

Pulmonary alveolar microlithiasis (PAM) is a rare diffuse lung disease characterised by the accumulation of calcium phosphate microliths within the alveoli. The causative mechanism of PAM has only recently been discovered, and involves a gene mutation of sodium phosphate co-transporter, which is expressed by alveolar epithelial cells. This mutation may have variable consequences on the clinical...

OBJECTIVE To assess the safety, efficacy, and stone-free rate (SFR) of mini-percutaneous nephrolithotomy (mini-PCNL) and retrograde intrarenal surgery (RIRS) for the management of lower calyceal stones of ⩽2 cm, and to determine the advantages and disadvantages of each. PATIENTS AND METHODS In all, 120 patients with lower calyceal stones of ⩽2 cm were randomly divided into two equal groups: G...

BACKGROUND This study was carried out to determine whether or not there is a significant relationship between the radiologic anatomy of the lower calyx, as seen on preoperative intravenous urography (IVU), and the outcome of stone clearance after extracorporeal shockwave lithotripsy (ESWL) for lower renal calyceal stones. METHODS Between June 1998 and April 2007, 112 patients with a solitary ...
