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...

OBJECTIVE To describe a surgical option in the resection of the distal third of the ureter and bladder cuff. MATERIAL AND METHOD Three nephroureterectomies were performed by the extraperitoneal access. The first was performed in a patient with vesicoureteral reflux, recurrent urinary infection and chronic renal failure; and two nephroureterectomies were performed for the treatment of upper ur...

Prostanoids produce significant effects in the ureter, particularly in response to obstruction. Ureteral obstruction is associated with increased prostanoid synthesis via cyclooxygenase induction; however, prostaglandin degradation mediated by 15-hydroxyprostaglandin dehydrogenase (PGDH) has not been evaluated in the ureter. The purpose of this study was to determine whether PGDH steady-state m...
