Urolithiasis can be defined as the clinical condition where the formation of crystal aggregates in the urinary tract results in kidney stones. The presence of a kidney stone in the human body can be externalized in very different ways, it can produce no symptoms but it can be associated with several pain caused for one or some of the following symptoms: gross or microscopic hematuria, obstructi...

BACKGROUND Outpatient surgery is critical to improve health care costs. The aim of the study was to prospectively evaluate the results of outpatient treatment of upper tract urinary stones by rigid or flexible ureteroscopy in a routine care setting. METHODS A database was created at the creation of the outpatient surgery department. 87 patients underwent 100 ureteroscopic procedures for urina...

OBJECTIVE To present our experience in minimally invasive management of urinary tract stones in patients with urinary diversion. MATERIALS AND METHODS We retrospectively reviewed 26 patients with urinary tract stones after cystectomy and urinary diversion. The types of urinary diversion were ileal conduit, colon conduit, ileal orthotopic neobladder in 19, 4, and 3 patients, respectively. At p...

INTRODUCTION Urinary stone formation is a frequent complication after continent urinary tract diversion and can require complex surgical management. Therapy options include open, percutaneous, transurethral, or transstomal stone fragmentation and extraction. The transstomal approach is considered to be one of the more complex treatment modalities. The patient's individual anatomy, minor stoma d...

BACKGROUND In recent years, bladder stones are increasing in China. However, a giant bladder stone is rarely found nowadays. METHODS A case of a 54-year-old man who presented with a >9-year history of urinary frequency and urgency and macrohematuria for the past 3 days, was examined by ultrasound scan, kidney-ureter-bladder x-ray, and computed tomography. Then, the patient received a cystolit...

Urinary proteins have been implicated as inhibitors of kidney stone formation (urolithiasis). As a proximal fluid, prefiltered by the kidneys, urine is an attractive biofluid for proteomic analysis in urologic conditions. However, it is necessary to correct for variations in urinary concentration. In our study, individual urine samples were normalized for this variation by using a total protein...

The estimated lifetime risk of nephrolithiasis is growing nowadays, and the formation of kidney stones is frequently promoted by hypercalciuria. Vitamin D, and especially its active metabolite calcitriol, increase digestive calcium absorption-as urinary calcium excretion is directly correlated with digestive calcium absorption, vitamin D metabolites could theoretically increase calciuria and pr...
