Predictor for Ureteral Stent Removal in Gynecological Cancer Patients with a Ureteral Obstruction

Predicting Factors for Stent Failure-Free Survival in Patients With a Malignant Ureteral Obstruction Managed With Ureteral Stents

PURPOSE To determine predictive factors for stent failure-free survival in patients treated with a retrograde ureteral stent for a malignant ureteral obstruction. MATERIALS AND METHODS We retrospectively reviewed 71 patients who underwent insertion of a cystoscopic ureteral stent due to a malignant ureteral obstruction between May 2004 and June 2011. Performance status, type of cancer, hydron...

Renin-angiotensin system and unilateral ureteral obstruction

Unilateral ureteral obstruction (UUO) is a clinical scenario that leads to obstructive nephropathy. UUO alters the expression of many mediators in the ipsilateral kidney. Renin-angiotensin system (RAS) is involved in UUO. Angiotensin II (Ang II) and angiotensin 1-7 (Ang 1-7) as the main arms of RAS influence kidney function which may alter by UUO. Ang II via Ang II receptor subtypes I (AT1R) ...

Success of ureteral stents for intrinsic ureteral obstruction.

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...

Repetitive ureteral stenting for management of transplant graft ureteral obstruction.

PURPOSE To review the use of repetitive stenting in the management of patients with ureteral obstruction after renal transplantation, with an emphasis on technique and functional graft outcome. MATERIALS AND METHODS Five adult renal allograft recipients with ureteral obstruction were managed with repetitive ureteral stenting. Their hospital records, office notes, and operative reports were re...
