Imaging findings of urinary tuberculosis on computerized tomography versus excretory urography: through 46 confirmed cases.

Tunis Med 2014 Dec;92(12):743-7

Background: Imaging findings of urinary tuberculosis (TB) on excretory urography (IVP) and CT have been reported to be nonspecific although CT may provide detailed informations. We performed a retrospective study of patients with proven urinary TB to compare imaging findings on IVP and CT and to make a systemic approach to imaging analysis of urinary TB.

Methods: Urinary TB was diagnosed in 46 patients who had IVP and CT examinations prior to definitive diagnosis and treatment. Read More

Pyocalycosis: a report of two cases of complicated hydrocalycosis.

Urol Int 2014 25;92(1):119-21. Epub 2013 Jul 25.

Department of Pediatric Surgery, Medical Faculty, Mersin University, Mersin, Turkey.

Hydrocalycosis is defined as cystic dilatation of a major calyx with a demonstrable connection to the renal pelvis and an epithelial lining of the cyst wall. Although this condition has long been known, there are no sufficient data concerning this pathology in the literature. In this study, we present two complicated hydrocalycosis--'pyocalycosis'--and discussed the therapeutic approaches. Read More

Idiopathic retroperitoneal fibrosis with particular perirenal and intrarenal extension associated with left renal artery stenosis. The atheromatous periaortitis with retroperitoneal fibrosis suggests a pathogenic relationship between atherosclerosis and fibrosis?

Spiral-CT (Multi-slice-Sensation 64) scan shows retroperitoneal fibrosis in relation with periaortitis that affects the thoracic and abdominal aorta. Read More

Percutaneous nephroscopic surgery.

Tae-Kon Hwang

Korean J Urol 2010 May 19;51(5):298-307. Epub 2010 May 19.

Department of Urology, Seoul St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Seoul, Korea.

With the development of techniques for percutaneous access and equipment to disintegrate calculi, percutaneous nephroscopic surgery is currently used by many urologists and is the procedure of choice for the removal of large renal calculi and the management of diverticula, intrarenal strictures, and urothelial cancer. Although it is more invasive than shock wave lithotripsy and retrograde ureteroscopic surgery, percutaneous nephroscopic surgery has been successfully performed with high efficiency and low morbidity in difficult renal anatomies and patient conditions. These advantages of minimal invasiveness were rapidly perceived and applied to the management of ureteropelvic junction obstruction, calyceal diverticulum, infundibular stenosis, and urothelial cancer.

Posterior Urethral Valves with Severe Unilateral Vesicoureteral Reflux in a 3-year-old Boy.

Ann Ib Postgrad Med 2007 Dec;5(2):73-6

In patients with posterior urethral valves (PUV), severe unilateral vesicoureteral reflux (VUR) is one of the three conditions associated with preservation of renal function. Others are urinary ascites or urinoma in newborns and large congenital bladder diverticula. These conditions most likely provide a pop-off mechanism preventing the development of high intravesical pressure. Read More

Renal hypertrophic infundibular stenosis.

Fetal Pediatr Pathol 2004 Jul-Aug;23(4):285-92

Department of Pathology, Louisiana State University Health Sciences Center, Children's Hospital of New Orleans, 200 Henry Clay Ave., New Orleans, LA 70118, USA.

Bilateral hydrocalycosis secondary to radiographically demonstrated bilateral infundibular stenosis required a left nephrectomy in an 18-year-old young man. The infundibular narrowing was due to marked hyperplasia of the submucosal smooth muscle. Scattered within the hypertrophic smooth muscle were rare spindled CD117-positive interstitial cells, similar to the cells responsible for peristaltic pacemaker activity within the gastrointestinal tract.

Imaging findings of urinary tuberculosis on excretory urography and computerized tomography.

J Urol 2003 Feb;169(2):524-8

Department of Diagnostic Radiology and Urology, Chang Gung Memorial Hospital and Chang Gung University, Taipei, Taiwan, Republic of China.

Purpose: We performed a retrospective study to analyze findings on excretory urography (IVP) and computerized tomography (CT) in patients with urinary tuberculosis.

Materials And Methods: In a 16-year period 53 patients with a total of 47 IVP and 33 CT examinations were diagnosed with urinary tuberculosis at our hospital. IVP and CT were reviewed and compared for certain imaging findings, including moth-eaten calices, renal parenchymal masses, an amputated infundibulum, autonephrectomy, thick urinary tract walls, urinary tract calcifications, renal parenchymal cavities, hydrocalycosis, hydronephrosis or hydroureter due to stricture, extra-urinary tubercular manifestations and renal parenchymal scarring.

A new cause of curvilinear renal calcification: calcified hydrocalycosis.

Eur J Radiol 2000 Oct;36(1):16-9

Department of Urology, Trakya University School of Medicine, 22030, Edirne, Turkey.

Although many causes of curvilinear renal calcifications have been described, calcified hydrocalycosis mimicking hydatid cyst has not previously been reported. We report a case of hydrocalycosis which was appeared as a curvilinear calcified cystic lesion resulted from staghorn calculus associated with xanthogranolomatous pyelonephritis (XGPN) on intravenous pyelography (IVU) and computed tomography (CT).

Circulating adhesion molecules and neutral endopeptidase enzymuria in patients with urolithiasis and hydronephrosis.

H Huang J Chen C Chen

Urology 2000 Jun;55(6):961-5

Department of Urology, National Taiwan University Hospital, Taipei, Taiwan, People's Republic of China.

Objectives: To measure the concentrations of adhesion molecules (intercellular adhesion molecule-1 ¿ICAM-1, E-selectin, and L-selectin) in the serum of patients with renal stones and patients with hydronephrosis caused by obstructive ureteral stones. Renal tubular enzymes were examined from their urine samples to evaluate whether neutral endopeptidase (NEP) behaved as traditional tubular enzyme markers (N-acetyl-beta-glucosaminidase ¿NAG and beta-galactosidase ¿beta-GAL) in their disease state.

Methods: Three groups were studied. Read More

Department of Urology, Sismanoglion General Hospital, University of Athens, Greece.

We present a very rare case of gigantic hydrocalycosis which was caused by an obstructed stone. It was so large that it displaced the rest kidney into the contralateral lumbar fossa giving the appearance of a crossed ectopic kidney. Read More

[Ultrasonic echography in the diagnosis of urolithiasis].

Vestn Rentgenol Radiol 1991 Jul-Aug(4):35-8

The paper is concerned with comparison of the results of ultrasound and x-ray investigation in 110 patients with urolithiasis. A possibility was established to diagnose roentgenonegative concrements in the kidneys and pelvicalyceal system with the help of ultrasound echography. The results of x-ray investigation were more reliable for the localization of uretero- and cystoliths. Read More

Infundibulopelvic dysgenesis: a spectrum of obstructive renal disease.

Urology 1990 Apr;35(4):334-7

Department of Surgery, University of Louisville School of Medicine, Kentucky.

Infundibulopelvic dysgenesis is an obstructive process of the pyelocalyceal system that is responsible for a spectrum of congenital renal disorders. The site and degree of narrowing in the infundibulopelvic system produce the various congenital anomalies like hydrocalycosis, calyceal diverticula, ureteropelvic junction stenosis, and multicystic kidney. A classification with illustrative cases is presented showing a common pathogenesis of these congenital obstructive anomalies. Read More
