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...

ureteral obstruction is relatively common after renal transplantation. a rare cause is the inguinal herniation of the transplant ureter. we report a case of late allograft renal transplant failure due to ureteral herniation as well as ureterovesical junction stenosis.

PURPOSE We undertook this study to evaluate the incidence, risk factors, management, and outcome of postoperative ureteral obstruction after endoscopic treatment for vesicoureteral reflux (VUR). MATERIALS AND METHODS Ninety patients undergoing endoscopic treatment for VUR were retrospectively reviewed and classified into two groups according to ureteral obstruction: the nonobstruction group (...

OBJECTIVE To evaluate predictive factors for retrograde ureteral stent failure in patients with non-urological malignant ureteral obstruction. MATERIALS AND METHODS Between 2005 and 2014, medical records of 284 malignant ureteral obstruction patients with 712 retrograde ureteral stent trials including 63 (22.2%) having bilateral malignant ureteral obstruction were retrospectively reviewed. Re...

idiopathic retroperitoneal fibrosis is a rare disorder of an unknown etiology characterized by an inflammatory proliferative fibrosing process that may involve the ureters in 80-100% of cases. â the present study was carried on a 38 years old man who was admitted to imam khomeini hospital with severe abdominal pain and renal failure. abdominal mri showed encasement of abdominal aorta and bilate...

71 Ureteral Obstruction IntRoduCtIon The ureters are fibromuscular ducts carrying urine from the kidney to the urinary bladder by peristaltic activity, which is transmitted from one muscle cell to the next (1). The ureters originate in the renal pelvices and travel retroperitoneally along the aorta and vena cava towards the urinary bladder. Near the pelvis they join the lateral ligament of the ...

PURPOSE Previous reports suggest a high success rate for retrograde ureteral stenting for intrinsic ureteral obstruction, but few preoperative predictors of success have been offered. We reviewed our experience to look for factors that suggest failure of stents for intrinsic ureteral obstruction. MATERIALS AND METHODS We retrospectively reviewed the outcome of retrograde ureteral stent placem...

The α8 integrin (Itga8) chain contributes to the regulation of cell proliferation and apoptosis in renal glomerular cells. In unilateral ureteral obstruction Itga8 is de novo expressed in the tubulointerstitium and a deficiency of Itga8 results in more severe renal fibrosis after unilateral ureteral obstruction. We hypothesized that the increased tubulointerstitial damage after unilateral urete...
