A 46-year-old female was referred to our hospital with a complaint of left flank pain. Ultrasongraphy and computed tomography demonstrated a left hydronephroureter due to stenosis with a ureteral mass in the left lower ureter. Retrograde pyelography revealed severe stricture of left lower ureter and brushing cytology showed papanicolaou class III. Ureteral tumor was suspected and left nephroure...

The cause is unknown but hereditary factors may play a role. Incontinence may be continuous (Fig. 4, page 11) or intermittent and even when both ureters are ectopic (bilateral ectopic ureter,), the dog can usually still pass a normal stream of urine, despite the copious leakage at other times. Diagnosis is by contrast radiography (special x-ray studies discussed in more detail in the section Ho...

Retrocaval ureter, also known as circumcaval ureter, is a rare congenital anomaly which commonly presents with loin pain in middle age group. Here, ureter passes between the inferior vena cava (IVC) and psoas muscle and gets compressed. Duplication of IVC is another rare congenital anomaly in the development of IVC. We present a case of a 49-year-old male who presented with loin pain and upon t...

Congenital obstructive malformations of the ureter are amongst the most common human birth defects. To date, the etiology of these diseases has remained largely unexplored, which has preempted any rational approach for therapeutic intervention. Here, we describe that obstructive ureter defects can arise from genetic insults affecting various subprograms of ureter development including formation...

INTRODUCTION Descent of the ureter into the inguinal canal or scrotum is rare but undoubtedly underreported. Most known cases were recognized at the time of surgery for hernia repair. We encountered five cases recently. PRESENTATION OF CASE We reviewed the records and CT images of five patients with inguinal hernias containing a segment of the ureter. All of our cases, like most reported case...

The ureter provides a way for urine to flow from the kidney to the bladder. Peristalsis in the ureter partially forces the urine flow, along with hydrostatic pressure. Ureteral diseases and a double J stent, which is commonly inserted in a ureteral stenosis or occlusion, disturb normal peristalsis. Ineffective or no peristalsis could make the contour of the ureter a tube, a funnel, or a combina...

Ureteroscopic lithotripsy using Swiss Lithoclast was performed in 411 cases from January 1996 to September 2007 in a single hospital. Medical records of 341 cases, in which Swiss Lithoclast was successfully applied, were available for this retrospective study. We used 9.5Fr and 10Fr Storz rigid ureteroscopes. A success was defined as being free of stone-related symptoms and residual stones larg...

The musculature of the ureter has a layered arrangement in which the internal layer is mainly longitudinal and the external layer is largely circular. There is, however, intermingling and migration of fascicles between layers. At the passage of the ureter through the bladder wall this layering is lost and all fascicles become oriented longitudinally. At the ureterovesical junction fibers of the...

Ureterostomy: Under intravenous pentobarbitone (30mg/~g) anaesthesia the ureter is approached retroperitoneally through a paravertebral incision extending from the costovertebral angle to the iliac crest. The muscles of the abdominal wall are cut along the line of incision. The ureter is identified in the retroperitoneal tissue and is drawn out without disturbing its blood supply. A longitudina...

Introduction: The prevalence of ectopic ureter (EU) is low and it is usually associated with urinary system duplication. In such cases, incontinence is a major complaint. Case Presentation: We present a case of a female patient that was diagnosed with ectopic ureter opening at the posterior vaginal fornix along with a duplicated pyeloureteral system after a regular diagnostic work-up that turne...
