PURPOSE The purposes of this study were to demonstrate the feasibility and accuracy of single-source dual-energy (DE) computed tomography (CT) with sequential data acquisition and a coregistration motion correction algorithm for urinary stone characterization and to evaluate the value of iterative reconstructions (IRs) in DE imaging. MATERIALS AND METHODS Thirty-five urinary stones were place...

introduction: aphallia is a very rare urogenital anomaly with incidence rate of 1 in 30,000,000. it usually coexists with other anomalies such as cardiovascular anomalies which are incompatible with normal life, and therefore infants are delivered stillbirth or live for a very short period of time. methods: we present an 18 months old boy with aphallia associated with congenital urethrorectal f...

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...

The factors formation the efficiency and safety of urinary stone crushing using holmium thulium fiber lasers were selected, substantiated normalized. A multifactorial integral criterion urolithiasis treatment by laser lithotripsy was formed analyzed. Recommendations are given for use stones.

INTRODUCTION We present a case of Alkaptonuria (AKU) presented with severe lower urinary tract symptoms (LUTS) secondary to extensive prostatic calculi deposited in the para prostatic diverticulum. Prostatic calculi are seen in chronic prostatitis, chronic pelvic pain syndrome and benign prostate hyperplasia; however, in patients with AKU, prostatic calculi and/or calcifications are more extens...

Medullary sponge kidney (MSK) is associated with recurrent stone formation, but the clinical phenotype is unclear because patients with other disorders may be incorrectly labeled MSK. We studied 12 patients with histologic findings pathognomonic of MSK. All patients had an endoscopically recognizable pattern of papillary malformation, which may be segmental or diffuse. Affected papillae are enl...

We present a male tetraplegic patient, who developed stones in neuropathic bladder six times within a span of three years. Unusual features of this case are: (1) This patient started developing stones in urinary bladder thirteen years after sustaining spinal cord injury. (2) He was performing intermittent catheterisation and did not have an indwelling catheter. (3) The presenting symptom of ves...

INTRODUCTION Computerized tomography of the urinary tract (CT-UT) has been established as the diagnostic procedure of choice for urinary stones. This study aimed to evaluate its role in predicting the outcome of percutaneous nephrolithotomy (PCNL) in terms of stone free rate and residual fragments. METHOD This prospective cohort study was conducted on 34 patients in the Urology Department of ...

The introduction and popularization of laparoscopic cholecystectomy has been accompanied with a considerable increase in perforation of gallbladder during this procedure (10% - 32%), with the occurrence of intraperitoneal bile spillage and the consequent increase in the incidence of lost gallstones (0.2% - 20%). Recently the complications associated with these stones have been documented in the...

OBJECTIVE To look at the role and safety of ureteroscopy for stone management in obese patients. METHODS We searched MEDLINE, PubMed and the Cochrane Library from January 1990 to June 2011 for results of ureteroscopy and stone treatment in obese patients. Inclusion criteria were all English language articles reporting on ureteroscopy in patients with morbid obesity. Data on the outcomes and c...
