Filter by:The incidence of stone disease of the urinary tract in children is increasingly increasing with a remarkable economic impact for its management. This incidence is variable according to race, geographic region, socio-economic status and dietary habits. Oxalo-calcium stones are the most common but the biochemical nature of urinary stones varies depending on the region where those of a phosphatic nature are characterized by a higher incidence in Europe. The diagnosis is confirmed by imaging. The unprepared abdomen (ASP) has low diagnostic accuracy. The scanner is the reference tool but remains an irradiating examination. Risk factors for disease recurrence include primarily the presence of an underlying urinary metabolic abnormality and young age. Urinary metabolic abnormalities vary from one study to another. The understanding of lithogenesis, its evaluation as well as the therapeutic options is essential for adequate and adapted management in the pediatric population.

To Compare the safety and efficacy of PNL in a modified flank-free supine position versus prone position in pediatric patients
The purpose of the study is to investigate whether the use of gentamicin-based irrigation fluid during ureteroscopy decreases the risk of UTIs and other post-operative infections after surgery.
This study tests whether hydroxycitrate, a molecule closely related to citrate, can reduce calcium phosphate stone recurrence.
Selective alpha-blockers have been used for the treatment of ureteric stones as medical expulsive therapy (MET). Recently they have been successfully used in passive ureteric dilatation before semirigid ureteroscopy. This study enables us to know the role of silodosin in ureteric dilatation to facilitate ureteral access sheath placement in Retrograde Intrarenal Surgery with flexible ureteroscopy.
Flexible ureteroscopy is characterized as first-line therapy for renal stones < 2 cm in size. Stones are commonly treated with dusting or fragmentation techniques which requires passage of stone fragments after surgery. Quoted stone free rate after flexible ureteroscopy is approximately 40-60% with a dusting technique. Residual fragments are often under 1mm in size and can layer in the lower pole of the kidney, complicating spontaneous stone passage. Improving the stone free rate after surgery decreases the need for secondary surgeries and decreases risk of future stone events. Numerous techniques have been proposed to increase stone passage including positional changes and percussion therapy. To date, there is overall limited data a lack of techniques that can be readily available in the outpatient setting, easily added to scheduled appointments, reproducible results and well tolerated by patients.
The goal of this observational study is to analyse the occurence of urinary calculi after bladder augmentation in children: - location of the calculi (kidney or bladder) - type of bladder augmentation with higher rate of urinary calculi and why - Find risk factors of urinary calculi in bladder augmentation (age, sex, other bladder procedures..)
This study was designed to investigate the effect of position and predictive factors on hypotension in patients performing percutaneous nephrolithotomy. Patients aged >18 years and ASA I-III who underwent general or regional anaesthesia were included in the study. Percutaneous access was performed in all patients with fluoroscopy in the prone position.
The aim of this study is to evaluate the clinical efficacy and safety of MET after ESWL in pediatric urolithiasis.
