Infantile hydronephrosis detected by ultrasonography poses a clinical dilemma on how to treat the condition. This article reports a retrospective study to evaluate infantile hydronephrosis due to suspected ureteropelvic junction (UPJ) obstruction by means of standardized diuretic renography and to speculate its usefulness for quantitative assessment and management of this condition. Between Nov...

OBJECTIVES To present our initial experience with laparoscopic pyeloplasty and to evaluate the safety and short-term outcome of this technique in children. METHODS Thirteen kidney units in twelve children underwent laparoscopic dismembered pyeloplasty for the management of ureteropelvic junction obstruction (UPJO) at our institution between 2005 and 2008. Patient age at surgery was 18-177 mon...

CAsE The patient is a 28-year old female with an obstructed ureteropelvic junction (UPJ) of the left moiety of a horseshoe kidney. The Da Vinci S robotic platform was used. After transperitoneal access was obtained, a window in the mesentery was identified, and the renal pelvis was exposed. A dismembered, spatulated pyeloplasty was performed with transposition of the UPJ to a more dependent por...

OBJECTIVE We evaluated the improvement of hydronephrosis longitudinally after laparoscopic dismembered Anderson-Hynes pyeloplasty in adult patients with ureteropelvic junction obstruction. MATERIAL AND METHODS Sixteen patients underwent laparoscopic pyeloplasty at our institution between January 2006 and June 2012. Hydronephrosis was assessed by ultrasound and intravenous pyelography at 3, 6,...

PURPOSE To evaluate the long-term success rate of endopyelotomy for the treatment of ureteropelvic junction (UPJ) obstruction. PATIENTS AND METHODS Between January 1995 and December 2003, 85 endopyelotomies (10 percutaneous, 75 retrograde) were performed in 77 patients with a mean age of 35.2 +/- 13.9 years. The mean number of procedures per patient was 1.14, with 69 patients undergoing a sin...

Introduction. Congenital pelviureteric junction obstruction (PUJO) is one of the most common causes of hydronephrosis. Historically, open dismembered pyeloplasty has been considered the gold standard intervention for correcting PUJO. The aim of this study was to compare the surgical and functional outcomes of three different approaches, namely, open, conventional laparoscopy, and robotic pyelop...

INTRODUCTION Robotic Pyeloplasty (RAP) is a technique for management of ureteropelvic junction obstruction (UPJO). PURPOSE To report outcomes of RAP for primary and secondary (after failed primary treatment) UPJO. MATERIALS AND METHODS Single institution data of adult RAP performed from 2007 to 2009 was collected retrospectively following approval by our IRB. Database analysis included pati...

PURPOSE To investigate the effects of the histopathologic pattern of obstructed ureteropelvic junction (UPJ) specimens, including collagen type 3, elastin, fibrosis and Cajal cells, on the outcome of pyeloplasty. MATERIALS AND METHODS Histopathological specimens obtained following Anderson-Hynes pyeloplasty from 52 patients with intrinsic ureteropelvic junction obstruction (UPJO) between Janu...
