Contrast Ct

The incidence and prevalence of urinary tract calculi has increased significantly during the past decade. Accurate fast diagnostic modalities were developed to cope with such an increased trend. To date, non-contrast CT scan remains the diagnostic modality of choice for evaluation of patients with urinary tract calculi. However, contrast CT scans are gaining more interest. In this review, both diagnostic modalities were reviewed with the advantages and disadvantages of each. Non-contrast CT scan is a rapid, accurate, less hazardous, less expensive imaging modality that has a high sensitivity in detection of urinary calculi as small as 3 mm. However, it cannot evaluate other probable causes of flank pain. Thus, contrast CT scans can be used in situations where clinical presentation is suspicious and the possibility of other differential diagnoses is considered. Contrast CT scans do not decrease the sensitivity of detecting urinary calculi, and they do have a higher sensitivity in detecting small grades of obstruction as well as evaluating other possible causes of flank pain such as neoplasms, infectious, or inflammatory aetiologies.

Objective.To critically evaluate the current literature in an effort to establish the current role of radiologic imaging, advances in computed tomography (CT) and standard film radiography in the diagnosis, and characterization of urinary tract calculi.Conclusion. CT has a valuable role when utilized prudently during surveillance of patients following endourological therapy. In this paper, we outline the basic principles relating to the effects of exposure to ionizing radiation as a result of CT scanning. We discuss the current developments in low-dose CT technology, which have resulted in significant reductions in CT radiation doses (to approximately one-third of what they were a decade ago) while preserving image quality. Finally, we will discuss an important recent development now commercially available on the latest generation of CT scanners, namely, dual energy imaging, which is showing promise in urinary tract imaging as a means of characterizing the composition of urinary tract calculi.

Abstract Background Urolithiasis is a clinically common benign disease in urology. Surgical treatments that are widely used in urolithiasis are percutaneous nephrolithotomy, rigid/flexible ureteroscopy, laparoscopic surgery, and endoscopic combined intrarenal surgery. The da Vinci surgical system is rarely used in the treatment of urolithiasis. In the current study, we report a case of multiple urinary tract calculi treated by robot-assisted laparoendoscopic single-site (RA-LESS) surgery. Case presentation A 49-year-old male patient was admitted to our hospital and diagnosed with multiple urinary tract calculi. He previously underwent right ureterolithotomy, laparoscopic cholecystectomy, and extracorporeal shockwave lithotripsy. Computed tomography (CT) scan and three-dimensional reconstruction CT image showed that multiple calculi were located in the right kidney, right upper ureter, and bladder. The preoperative glomerular filtration rate (GFR) were 17.81 ml/min (right kidney) and 53.11 ml/min (left kidney). We utilized the da Vinci system docking with a single-site port to perform pyelolithotomy, ureterolithotomy, and cystolithotomy, simultaneously. The operative time was 135 min and estimated blood loss was 30 ml. The postoperative hospital stay was 5 days. Three months after surgery, the serum creatinine and urea nitrogen levels dropped to a normal range, and no residual fragments were found in the CT scan. The postoperative GFR were 26.33 ml/min (right kidney) and 55.25 ml/min (left kidney). Conclusions RA-LESS surgery is a safe and effective surgical procedure in the treatment of multiple urinary tract calculi; however, further investigation is needed to validate its long-term therapeutic effect.

Prompt Diagnosis

Urinary Tract Calculi Impaction / finding in the male urethra is extremely uncommon and can usually be secondary to upper urinary tract calculus formation or primarily arising from the urethra either due to stricture or post-trauma. There is paucity of urethral stricture report in Nigeria, thus this case is reported to highlight the role of imaging in the prompt diagnosis and management of urethral diseases; and to advise urologists to at least always request for imaging modality in their routine evaluation of urethral pathologies. We report a case of a 55 years old male farmer who presented in the Accident and Emergency Unit of our facility with signs and symptoms of acute urinary retention. A working diagnosis of urethral stricture was entertained and prompt diagnosis was made on image. Existing literatures outlining the pathologies, clinical presentation, therapeutic consideration and imaging as it relates to urethral calculi were reviewed. We thus concluded that imaging is very vital and fundamental in order to correctly assess any form of urethral pathology.Asian Journal of Medical Sciences Vol. 7(3) 2016 118-120

Vitamin A (retinol) is one of the key elements for regulating the immune response and controls the division and differentiation of epithelial cells of the mucous membranes of the bronchopulmonary system, gastrointestinal tract, urinary tract, eyes, etc. Its significance in the context of the COVID‑19 pandemic is difficult to overestimate. However, a number of studies conducted in the past have associated the additional intake of vitamin A with an increased risk of developing cancer, as a result of which vitamin A was practically excluded from therapeutic practice in developed countries. Our review highlights the role of vitamin A in maintaining human health and the latest data on its effect on the development mechanisms of somatic pathology.
