Fibroepithelial polyps (FEPs) are rare benign ureteral neoplasms of mesodermal origin. As an intrinsic cause of ureteropelvic junction obstruction (UPJO) they are very uncommon. Excretory urography and diuretic renography used by many urologists to diagnose a UPJO may not detect the ureteral polyp. We present a case of ureteropelvic junction obstruction caused by a fibroepithelial polyp, which ...

Objectives: To assess the feasibility and effectiveness of transperitoneal laparoscopic pyeloplasty in the treatment of ureteropelvic junction obstruction. Laparoscopic pyeloplasty has been shown to have a success rate comparable to that of the open surgical approach. We report the results of our first 15 cases of transperitoneal dismembered pyeloplasty. Patients and methods: From August 2006 t...

INTRODUCTION Although most urologists agree that failures after laparoscopic pyeloplasty occur usually within a year after the operation, late failures are also reported. AIM To assess late results of laparoscopic pyeloplasty. MATERIAL AND METHODS Seventy-eight of ninety-five patients who had been operated on between November 2001 and September 2009 were notified about the possibility of di...

BACKGROUND The aim of this study was to assess the clinical relevance of diuresis renal scintigraphy after simultaneously administered radiopharmaceutical and diuretic (DRS "F-0") in diagnosing obstruction of upper urinary tract in children with previously documented hydronephrosis and ureterohydronephrosis, analyzing the value of qualitative and quantitative scintigraphy parameters. MATERIAL...

UNLABELLED The purpose of this study was to evaluate the feasibility of modifying diuresis renography by the simultaneous administration of 99mTc-mercaptoacetyltriglycine (MAG3) and furosemide in the investigation of hydronephrosis and hydroureteronephrosis in infants and children. Two parameters were assessed: the diuretic response in normal kidneys and the ability of the F+0 study to differen...
