In aggressive cases, endometriosis can perturb the urogenital tract, in particular the ureter, which can potentially result in ureteral compression or stenosis. Even though this is rare, consequences are dramatic, such as hydronephrosis or organ failure. The present standard intervention comprises the resection of affected tissues and endometriosis foci combined with adjuvant hormonal therapy. ...

A 3-month-old, Labrador bitch presented with urinary incontinence. A unilateral, ectopic ureter was diagnosed with ultrasound without the aid of additional contrast radiographic techniques. Ipsilateral hydroureter and mild hydronephrosis were also present. At the level of the bladder trigone the ectopic ureter became intramural and this was clearly demonstrable with ultrasound. The opening of t...

Retrocaval ureter is a very rare congenital malformation. We report 10 years’ experience in the diagnosis and treatment of retrocaval ureter, case series 3 cases two different countries Middle East. This retrospective study that included ureters Egypt Saudi Arabia. Standard open ureteroureteric anastomosis was performed through flank incision for each case. Patients’ symptoms were re-evaluated ...

endometriosis is the presence of benign endometrial glands and stroma outside the uterus. urinary system involvement by endometriosis is a rare occurrence accounting for only 1.5 % of all endometriosis cases. case 1. the patient was a 41 years old woman admitted for right flank pain. the physical and gynaecologic examination was unyielding. intravenous urography (ivu) revealed stenosis in dista...

The configuration of the electrotonic potential and the action potential observed by the double sucrose-gap method was similar to that observed with a microelectrode inserted into a cell in the center pool between the gaps. In the taenia and the ureter, the evoked spike was larger in low Na or in Na-free (sucrose substitute) solution than in normal solution. However, the plateau component in th...

A bifid ureter is a congenital renal tract abnormality due to some error or disturbance during development. It is an example of incomplete duplication of urinary collecting system. A bifid ureter is formed when a duplex kidney drain into separate ureters that unite before attending the bladder. Bifid ureter is reported to be twice more common in females and on the right side. The majority of th...

The capacity of ureteral stents to enhance the conveyance of urine from kidney to bladder is the critical function for patients that require them. The flow path in and around the stent is not a trivial one, particularly if some elements of peristalsis are present in the ureter. This paper details a numerical flow simulation for an axially symmetric stented ureter segment. The flow of urine thro...

Purpose This study aims to assess the predictive factors and treatment outcomes of Steinstrasse formation following shock wave lithotripsy (SWL) for ureter stone. Materials and Methods The medical records of 1,418 ureter stone patients who underwent one-session SWL from November 2005 to May 2013 at our medical institute were retrospectively reviewed. Finally, 551 patients met inclusion criter...
