Dear Editor: The ureteral stents are defined as devices that are inserted inside obstructive ureters to maintain patency. Ureteral obstruction caused by extrinsic compression is a challenge in the management of malignant diseases. First, adequate stent placement across an obstructed ureter does not necessarily guarantee urine patency. Moreover, the stent is poorly tolerated, severely impairing ...

conclusions this case raises awareness on the lack of visualization of ureteral flux during conventional cystoscopic evaluation in patients with renal failure undergoing pelvic organ prolapse repair, while also emphasizing the importance of confirming ureteral patency via retrograde ureteral intubation when cystoscopy is non-diagnostic. background pelvic floor reconstruction can result in obstr...

OBJECTIVE To evaluate the rate of intrinsic ureteral endometriosis in patients presenting with severe ureteral endometriosis. DESIGN Observational study between June 1992 and December 2007. SETTING University tertiary referral center. PATIENT(S) Twenty-nine patients presenting deeply infiltrating endometriosis (DIE) with severe ureteral endometriosis. Severe ureteral endometriosis was def...

From July, 1987 to Oct, 1989 , 104 patients underwent 111 transurethral ureteroscopy procedures at the Air Force Medical Center. All intramural ureters were dilated by flexible metal dilators. The overall success rate for ureteral stone removal was 95.8 per cent. Ureteroscopy was done for evaluation of gross hematuria, strictures, ureteral stent, and ureteral and pyelocalyceal tumors. The ...

30 cases of obstructing proximal ureteral stones at the level of L3-L5 which could not be pushed back into the pelvis and passed by a guide wire under epidural anesthesia, were removed percutaneously with the rigid ureteroscope. Multiple stones in one ureter, bilateral ureteral stones and a ureteral stone of a solitary kidney were removed successfully in one session showing the reliability...

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...

Fibrosis is the end point of most renal diseases, and several glycosaminoglycans have been shown to attenuate this process. Marine invertebrate glycosaminoglycans with unique structures have opened the possibility to test these new compounds on renal fibrosis. The effect of a fucosylated chondroitin sulfate from an echinoderm marine species is reported with the use of a model of renal fibrosis ...

Traditional Chinese medicine (TCM) has been proposed to prevent urolithiasis. In China, Flos carthami (FC, also known as Carthamus tinctorius) (Safflower; Chinese name: Hong Hua/) has been used to treat urological diseases for centuries. We previously performed a screening and confirmed the in vivo antilithic effect of FC extract. Here, ex vivo organ bath experiment was further performed to stu...

Ureteral stictures cross a broad range of severity and can arise from infectious, iatrogenic, and disease-related sources. These can be amongst the most difficult urologic diseases to treat effectively. In this session, we will review various treatment options that can be applied effectively to improving treatment outcomes.
