The Resonance(®) metallic ureteral stent is one of the latest additions to the urologist's armamentarium in managing ureteral obstruction. One advantage of this stent over traditional polymer-based stents is resistance to encrustation with stone material, which allows longer dwell times and less frequent exchange procedures. Although exchanging a metallic stent is slightly more complicated than...

endourologic pyeloplasty is being a substitute of open pyeloplasty in management of ureteropelvic junction obstruction. this procedure can be done in different manners like balloon dilation, cold knife and electrosurgical endoureterotomy, accucise and lasers.a 47 year old woman referred with history of previous open pyeloplasty. hydronephrosis of right kidney with unremarkable t ½ was found in ...

A 67-year-old male renal transplant patient presented with a right inguinal bulging mass, and was diagnosed with a right indirect inguinal hernia. The day following inguinal herniorrhaphy, serum creatinine became elevated. The patient was oliguric and had abdominal pain on the first day after inguinal herniorrhaphy with a mesh. We diagnosed him with acute renal failure and subsequently performe...

Urothelial bladder cancer (UBC) is the second most common type of malignancy in the urinary tract with high frequency of recurrence and high progression rate (1). European Urology Association (EAU) guidelines recommend radical cystectomy (RC) for muscle invasive bladder cancer or non-muscle invasive bladder cancer at ...

PURPOSE The purpose of this study was to develop and test a method for measuring pressure in the upper urinary tract during ureteroscopic operations and to evaluate its efficacy and clinical significance. METHODS A total of 44 patients, each with a ureteral calculus in the proximal ureteral segment, were enrolled in the study group: 21 patients with an acute and 23 with a chronic obstruction....

Objective. To create a ureteral obstruction experimental model that can be proved through (99m)Tc-DTPA renal scintigraphy and histopathological studies, without causing total renal function loss. Materials and Methods. Ten New Zealand white rabbits were submitted to a surgical experiment to create a model of unilateral obstruction to urinary flow. Surgery procedure provided unilateral ureteral ...

Data on the outcome of aneurysmal chronic peri-aortitis ('inflammatory aneurysm') after open surgical aneurysm repair are few and contradictory. To what extent this inflammatory process is reversed after endovascular aneurysm repair (EVAR) is even more unclear. The objective of this review was to study the outcome of peri-aortic fibrosis (PAF) and ureteral obstruction in patients with aneurysma...

56 percutaneous nephrostomies were evaluated in 50 patients, with a malignant underlying factor in 32 and benign conditions in 24. the clinical indication was decompression for supravesical obstruction with or without azotemia in the majority of cases. less common indications were management of ureteral fistula, ureteral stricture dilatation, and pelvic stone extraction. serious complications w...

double-j (dj) stents are the main tools used in urological practice for prevention and treatment of obstruction. stenting is also mandatory after complicated ureteroscopy or tul (transureteral lithotripsy). known complications are upper migration of dj stents into the kidney and lower migration to the bladder. in a man with an impacted right lower ureteral stone, a dj stent was placed because t...
