Aims: Nephrolithiasis and nephrocalcinosis are progressive diseases that can lead to renal impairment. The aim of this analysis was to evaluate aetiological factors, metabolic screening, diagnostic algorithm, treatment, prophylactic measures and follow-up in children with nephrolithiasis and nephrocalcinosis. Patients and methods: Retrospective study of 63 children (36 males, 27 females) with n...

BACKGROUND We desire to review our experience with bladder augmentation in spina bifida patients followed in a transitional and adult urologic practice. This paper will specifically focus on three major complications: bladder calculi, the most frequent complication found following bladder augmentation, perforation of the augmentation, its most lethal complication and finally we will address los...

I read the article by Dr Chou and associates [1] with interest. They evaluated the secondary signs associated with ureteral obstruction from calcium and uric acid stones. They used unenhanced helical computed tomography (UCT) in order to assess the kidneys in those patients, and observed that UCT reliably showed secondary changes (such as rim sign, hydroureter, perirenal stranding, renal densit...

Objective: To evaluate the efficacy of ambulatory extracorporeal shock wave lithotripsy monotherapy in the treatment of staghorn calculi. Materials and Methods: Using piezoelectric lithotriptors (EDAP-LT01 or LT02), 268 staghorn calculi were treated. One hundred and forty three were complete and 125 were partial (65 filled the renal pelvis + one calyceal system, and 60 filled the renal pelvis +...

Computer tomography through the kidneys, ureters and bladder (CT KUB) is the mainstay investigation of suspected renal tract calculi. However, several pathologies other than renal tract calculi can cause apparent urinary bladder calcification. We describe the case of a 45 year old man who presented with left sided renal colic. Prone CT KUB performed on admission revealed a calcified urachal rem...

Introduction: Urolithiasis is rare in developed countries. Staghorn calculi are a type of upper urinary tract stone that involves the renal pelvis and extends into at least two calyces. Although all types of urinary stones can potentially form staghorn calculi, approximately 75% are composed of a struvite matrix and are generally associated with urinary tract infection caused by urea -splitting...

Metaplastic changes in the renal pelvis are infrequent and may be malignant transformations to adenocarcinoma. The current study reports a case of intestinal metaplasia in the right renal pelvis, which was associated with staghorn calculi, in a 56-year-old female. The patient underwent a percutaneous nephrolithotomy. Immunohistochemical assessment of the mucosa of the renal pelvis revealed the ...
