Spontaneous Ureteropelvic Junction Rupture Caused by a Small Distal Ureteral Calculus
نویسندگان
چکیده
To the Editor: Spontaneous ureteral rupture is rare, and urolithiasis is the most common cause.[1,2] The underlying mechanism may be the pressure around the ureteral wall due to stone impaction or a tear during the stone passage. Smaller distal stones exert higher intraureteral pressures than do larger proximal stones because of the greater length of obstructed ureter and the smaller diameter of the distal ureter.[2]

Spontaneous Perforation of the UPJ: A Case Report and Review of the Literature
Spontaneous rupture of the ureter is an uncommon condition defined by non-traumatic extravasation of urine. Causative factors leading to rupture include urinary calculi, malignancies, instrumentation or trauma. Ureteral rupture can lead to numerous complications, including abscess formation, urinomas, and urosepsis. Minimal literature is available regarding spontaneous ureteral perforation, esp...
متن کاملUreteral stone location at emergency room presentation with colic.
PURPOSE It is thought that the 3 narrowest points of the ureter are the ureteropelvic junction, the point where the ureter crosses anterior to the iliac vessels and the ureterovesical junction. Textbooks describe these 3 sites as the most likely places for ureteral stones to lodge. We defined the stone position in the ureter when patients first present to the emergency department with colic. ...

This case report describes a distal ureteral atresia along with ureteropelvic junction obstruction which occurred in a 19-month-old female child. It is easily to be misdiagnosed as mere ureteropelvic junction obstruction and omitted the combined diagnosis of distal ureteral atresia. Dismembered pyeloplasty was done in local hospital after admission, however with the result of recurrent fever wh...

A 10-year-old girl sustained a ureteropelvic junction disruption and distal ureter injury associated with the Chance fracture following a traffic accident. She was sitting on the rear seat of a car wearing a lap belt. Extensive small bowel mesenteric trauma was noted. Radiography revealed a left haemothorax with mediastinal shift and an unstable flexion-distraction vertebral fracture at L2 (Cha...
متن کاملLaparoscopic Anderson-Hynes procedure as a treatment of ureteropelvic junction obstruction caused by fibroepithelial polyp
Fibroepithelial polyps (FEPs) are rare benign ureteral neoplasms of mesodermal origin. As an intrinsic cause of ureteropelvic junction obstruction (UPJO) they are very uncommon. Excretory urography and diuretic renography used by many urologists to diagnose a UPJO may not detect the ureteral polyp. We present a case of ureteropelvic junction obstruction caused by a fibroepithelial polyp, which ...
