Abstract Background: Stphylococcus cohnii is an organism of coagulase negative species which is considered as normal flora. However, it has been isolated from urinary tract infections and surgical prostheses but its relation with staghorn stones has not been reported, yet. Case Presentation: A 50-years-old woman presented with left renal staghorn stone in June 2014. She had bilateral staghorn...

Objectives: Percutaneous nephrolithotomy on staghorn calculi is challenging for urologists because it is difficult to remove all of the stones. The purpose of this study was to evaluate the associated factors of stone-free rate after primary percutaneous nephrolithotomy on staghorn calculi in a large series of patients at a single, tertiary referral, endourologic stone center. Methods: We colle...

OBJECTIVES To evaluate a supracostal approach for percutaneous nephrolithotomy (PCNL) of staghorn calculi through a prospective study and review of previously reported cases. METHODS From June 2009 to November 2011, 40 patients with staghorn calculi were scheduled for supracostal S-PCNL in a prospective study. Of the 40 renal units, 16 (40%) had a complete staghorn and 24 (60%) had a partial ...

OBJECTIVE To report a complication of a staghorn stone in a non-functioning right kidney. METHODS We present a 47 year old female with right lumbar pain and history of recurrent urinary tract infection (UTI). After an acute pyelonephritis episode, a right staghorn stone was diagnosed in a non-functioning right kidney. RESULTS During right nephrectomy, we found a renocolic fistula not observ...

A 50-year-old woman presented with a 2-years history of chronic flanc and hematuria. Plain abdominal radiography was performed showing bilateral complete staghorn calculi. Urinalysis and urine culture revealed a urinary infection by Proteus Morganii. Biologic investigations did not show any matabolic disorder. The urinary infection was treated by antibiotics and the stone by a combination of pe...

Urinary stone is a worldwide disease and percutaneous nephrolithotomy (PCNL) is the most commonly used operation for staghorn calculi. Research indicated that SFR for staghorn calculi in one stage of PCNL showed 50%-91% results, under standard operation, standard instrument and professional treatment route. The present study aimed to explore the clinical factors of stone free rates (SFR) after ...
