This study assessed the diagnostic value of obtaining an additional upright kidney-ureter-bladder (KUB) radiograph during routine intravenous urography (IVU). Of 164 patients who underwent IVU with an additional upright KUB, the upright view provided diagnostic benefit in 72 patients (43.9%), identifying issues like nephroptosis, better filling of the collecting system, differentiation of phleboliths from stones, and evaluation of emptying. While newer modalities have advantages, upright positioning remains a simple way for IVU to provide unique diagnostic information by leveraging gravitational effects.

The patient presented with acute renal colic and was found to have multiple soft tissue calcifications and hydroureteronephrosis on the right side. CT imaging revealed numerous calcified lesions throughout the muscles and brain. Our diagnosis is cysticercosis based on the characteristic appearance. Additional tests such as serology would help confirm. Treatment with anti-cysticercosis drugs and ureteral stenting is recommended given the similarities to reported cases of cysticercosis presenting in this manner.

1. The urinary and genital systems develop from a common intermediate mesoderm and initially share a common cavity called the cloaca.
2. The kidneys develop through three successive stages - the pronephros, mesonephros, and metanephros - with the metanephros forming the permanent kidneys.
3. The ureters develop from the mesonephric ducts and later join the bladder, which develops from the urogenital sinus. The bladder remains connected to the umbilicus by the urachus in early development.
This document summarizes investigations and management of urolithiasis or kidney stones. It discusses basic laboratory tests on urine and blood to identify stones, as well as various imaging techniques like KUB X-rays, ultrasounds, IVUs and CTUs. Management options are outlined depending on stone size and location, including observation, chemolysis, shockwave lithotripsy, ureteroscopic lithotripsy, percutaneous procedures, and open surgery. The document emphasizes the importance of preventing recurrent stones through lifestyle changes, medications, and treating underlying metabolic issues.

Cardinality and participation constraintsNikhil Deswal
油
Cardinality and participation constraints define the relationships between entities in a database. Cardinality constraints specify the maximum number of entities that can participate in a relationship, such as one-to-one, one-to-many, or many-to-many. Participation constraints indicate whether participation of an entity in a relationship is total, meaning every entity must participate, or partial, meaning only some entities participate. These constraints help maintain data integrity and ensure only valid relationships are stored in the database.
RGU MCU and its interpretation in pathology of Urinary Bladder & Urethradbc9427
油
This document discusses the embryology, anatomy, imaging modalities, and contrast agents used in evaluating the urinary bladder and urethra. It provides details on retrograde urethrography technique, including indications, equipment, preparation, procedure, filming, and potential complications. Common congenital and acquired diseases of the urinary bladder are also summarized, such as bladder exstrophy, urachal anomalies, diverticula, fistulas, and calculi.
This document provides information about retrograde urethrography (RGU) and micturating cystourethrography (MCU). It defines these procedures, describes how they are performed, and what radiographic views are obtained. RGU involves retrograde injection of contrast into the urethra and is used to evaluate the membranous and anterior urethra. MCU involves filling the bladder with contrast and imaging the patient voiding to evaluate the bladder neck and urethra. Both procedures provide diagnostic information for conditions like strictures, reflux, fistulas and anatomical abnormalities.
A presentation about Imaging the urinary tract using contrast.
contains 45 slides, and covers the following methods :
1 - Antegrade urography
2 - Retrograde urography
3 - Retrograde cystography
4 - Voiding cystography
5 - Retrograde Urethrography
Intravenous urography is covered in a separate presentation, that you can read and download from here :

This presentation was prepared and presented by me in the tutorials of the Radiology Department of Sebha Medical Center.
This document discusses urolithiasis (kidney stones). It begins by defining urolithiasis and noting its prevalence and cost. It then covers the epidemiology, types, symptoms, diagnosis, and management of kidney stones. The main points are that kidney stones can form anywhere in the urinary tract, have a lifetime risk of 2-20% depending on location, and are most commonly treated through active medical expulsion or minimally invasive surgeries like ESWL or ureteroscopy. Surgical intervention is indicated for large or obstructing stones, infection, or if conservative measures fail.
This document discusses renal calculi (kidney stones). It defines renal calculi and reviews the anatomy and physiology of the renal system. It examines the etiology, risk factors, and pathogenesis of renal calculi. It also describes the clinical manifestations, diagnostic studies, medical and surgical management, nursing management including nursing diagnoses, and prevention of renal calculi.
This document provides information about antegrade and retrograde pyelography tests. Antegrade pyelography involves injecting dye directly into the kidney through a needle to outline the renal system and detect blockages on x-rays. Retrograde pyelography uses dye injected into the ureters through a catheter during cystoscopy to visualize the ureters and kidneys. Both tests carry risks of dye reactions and infections. The document describes the procedures, uses, risks, and sample images for each test.

Metaphorical signs in computed tomography of chest and abdomen 2014Lan 畉ng
油
The document is a chapter from a book on metaphorical signs seen on computed tomography (CT) scans of the chest and abdomen. It discusses several signs seen on CT scans and what they typically indicate. The chapter includes sections on the saber-sheath trachea sign indicating tracheal collapse, the eggshell calcification and rim enhancement sign seen in conditions like silicosis and tuberculosis, and the split pleura sign which is considered the most reliable for distinguishing empyemas from other pleural effusions. It provides images and descriptions of these and other common radiological signs seen on CT scans.
