PURPOSE Urosepsis due to manipulation during percutaneous nephrolithotomy (PCNL) can be catastrophic despite prophylactic antibiotic coverage, and negative midstream urine culture and sensitivity testing (C&S). It has been postulated that bacteria in the stone may be responsible for systemic infection. In this prospective study we determined the correlation(More)
PURPOSE We sought to identify whether changes in technology and local practice have improved outcomes in the minimally invasive management of pediatric stone disease. MATERIALS AND METHODS We reviewed retrospectively case notes and imaging from 1988 to 2003, noting treatment modality, stone-free rates, ancillary therapy and complications. RESULTS A(More)
INTRODUCTION Horseshoe kidney is the commonest congenital renal fusion anomaly, and is often complicated by urolithiasis. We focus on our 16 years of experience with stone management in horseshoe kidneys. MATERIALS AND METHODS We reviewed the progress of 44 patients treated between 1987 and 2002. Shock wave lithotripsy (SWL) was used in 25 patients; the(More)
OBJECTIVE To review the safety and efficacy of supracostal puncture during percutaneous nephrolithotomy (PCNL) for renal calculi. PATIENTS AND METHODS Over a 12-year period, 66 patients had either an upper-pole puncture alone or combined with middle- or lower-pole puncture during PCNL for renal calculi. All punctures were made by an experienced(More)
OBJECTIVE To review patients with an extended follow-up after extracorporeal shock wave lithotripsy (ESWL) or percutaneous nephrolithotomy (PCNL) for calyceal diverticular stones (CDS), over a 15-year period, assessing the long-term outcome. PATIENTS AND METHODS In all, 56 patients were treated for symptomatic CDS disease by ESWL (38) or PCNL (18). The(More)
OBJECTIVE To evaluate whether 1 week of ciprofloxacin before percutaneous nephrolithotomy (PCNL) in patients with stones of > or = 20 mm or pelvicalyceal dilatation, reduces urosepsis, as we previously reported that such patients have four times the risk of urosepsis after PCNL. PATIENTS AND METHODS Patients undergoing PCNL, and who fulfilled strict(More)
In this paper, a simulation-based synthesis tool, AMIGO, for analog cell sizing is presented. AMIGO is based upon genetic optimization techniques adapted to circuit sizing. A framework has been developed using TCL/TK language that allows the designer to set the optimization problem, define complex constraint functions, watch the progress of optimization,(More)
PURPOSE To report our experience with ureteroscopy in the treatment of pediatric urinary tract calculi and present a review of the literature. PATIENTS AND METHODS Between 1988 and 2003, 52 ureteroscopic procedures were performed in 25 male and 10 female children aged 11 months to 15 years (mean 5.9 years). Using a semirigid 6.8F 43-cm ureteroscope and(More)
BACKGROUND AND PURPOSE Extracorporeal Shockwave Lithotripsy (SWL) is now the best noninvasive treatment for renal calculi, rendering many patients stone free. This prospective study was performed to evaluate the short-term results of patients undergoing SWL with the Dornier Compact Delta lithotripter for all renal calculi. PATIENTS AND METHODS Between(More)
AIM To evaluate whether the overall safety and efficacy profile of percutaneous surgery for urinary stone disease in older (>70 years) patients might influence the decision for the procedure in the elderly. MATERIALS AND METHODS A large database was created from our patients (n = 1058) who underwent percutaneous surgery for stone disease between 1991 and(More)
