INTRODUCTION To investigate whether there was a protective effect of melatonin on apoptotic mechanisms after an acute unilateral obstruction of the kidney. MATERIAL AND METHODS A total of 25 rats consisting of five groups were used in the study, designated as follows: Group 1: control, Group 2: sham, Group 3: unilateral ureteral obstruction treated with only saline, Group 4: unilateral ureter...

A variety of pelvic, retroperitoneal or metastatic malignancies may cause ureteral obstruction either by direct invasion or external compression of the ureter. Ureteral obstruction is a cause of significant morbidity and mortality in cancer patients these patients may suffer from acute or chronic pain, acute renal failure or subacute impairment of renal function, and they are at risk for infect...

OBJECTIVE Ureteral obstruction is one of the complications of testicular tumor with retroperitoneal lymph node metastasis that requires ureteral stenting for management. We elucidated the clinical courses of ureteral obstructions and changes in renal functions in patients with indwelling ureteral stenting. METHODS The medical records of 56 patients who were treated for metastatic testicular t...

Objective To report the management of urinary tract obstruction and infection in a pregnant woman with unrepaired bladder exstrophy. Case Report A 27-year-old pregnant woman with unrepaired bladder exstrophy was referred to our hospital with a complaint of bilateral flank pain in the second trimester. After two-dimensional abdominal ultrasound, magnetic resonance imaging and a urine analysis,...

Robotic-assisted ureteral reimplantations were performed on 3 patients at a single institution, 2 with Boari flap and psoas hitch and 1 with psoas hitch alone. These were for urothelial carcinoma of the distal ureter, ureteral obstruction caused by distal ureteral endometriosis, and ureteral transaction during gynecologic surgery. We used intraoperative ureteroscopy to confirm tumor margins as ...

Background Kidney allograft dysfunction is common and often reversible but can lead to allograft loss if not promptly evaluated. Transplant ureteral obstruction in an inguinal hernia is a rare cause of allograft dysfunction, but early recognition may prevent allograft loss. Case Presentation We present a case of a man with acute kidney allograft dysfunction who received a deceased donor kidne...

= A bs t r ac t = Partial ureteral obstruction in rats has been usually created by implanting the mid ureter into the psoas muscle. However, this method does not allow us to choose the obstruction site or the degree of obstruction. On the other hand, the extrinsic stent insertion method needs highly sophisticated operation skill. Hence, we tried t o make a new experimental model using a bisecte...

Background: Ovarian remnant syndrome (ORS) is characterized by functional ovarian tissue following bilateral salpingo-oophorectomy. ORS presents with pelvic pain or mass, but may also present with urinary tract symptoms resulting from enlarging residual tissue. Case: A 37-year-old woman presented with pelvic pain radiating to her flank due to ureteral obstruction from an enlarging ovarian cyst ...

Urolithiasis in cats Calcium oxalate (CaOx) containing uroliths are the predominant stone type identified in the ureter of cats. Unfortunately, medical dissolution of CaOx uroliths is not available and so surgical removal or the placement of a ureteral stent is often recommended if the stones are causing clinical disease. If intervention is necessary, it is not always clear how long one should ...
