OBJECTIVES To report the long-term outcome of laparoscopic retroperitoneal pyeloplasty (LRP) in adults. PATIENTS AND METHODS Thirty patients underwent LRP for primary pelvi-ureteric junction obstruction (PUJO). Anderson-Hynes dismembered pyeloplasty was used in 28 patients and a Foley Y-V pyeloplasty in two. A JJ stent was inserted antegradely during the procedure. Patients were reviewed at 1...

OBJECTIVE To evaluate the efficacy of laparoscopic pyeloplasty relative to retrograde balloon dilatation for the treatment of ureteropelvic junction obstruction (UPJO). METHODS This retrospective study enrolled UPJO patients with stricture length < 2 cm who had been treated with laparoscopic pyeloplasty (LP; 44 cases) or balloon dilatation (BD; 38 cases) from Jan 2010 to Jan 2012, according t...

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...

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...

OBJECTIVE To determine the efficacy of retrograde endopyelotomy for the treatment of pelvi-ureteric junction (PUJ) obstruction using the Acucise ureteric balloon cutting catheter. PATIENTS AND METHODS Between February 1995 and July 1997, 13 consecutive patients with primary PUJ obstruction underwent Acucise endopyelotomy at our institution. The mean follow-up was 17.7 months (range 7-33). The...

OBJECTIVES To evaluate and compare the relative contribution of different therapeutic agents for renoprotection against complete unilateral ureteric obstruction (UUO), using a rabbit model sampled at different times. MATERIALS AND METHODS Eighty-four male New Zealand White rabbits were divided into seven groups of 12 rabbits; a sham group, a control (left UUO + no medication) or left UUO and ...

INTRODUCTION It is believed that lower pole crossing vessels may play an important role in the etiology of ureteropelvic junction obstruction (UPJO). A conventional operative technique, which seems to be widely used in patients with UPJO, is Anderson-Hynes (A-H) plasty with dorsal transposition of the vessel. An attractive alternative to dorsal transposition of the vessel might be its cephalad ...

The aim of this study was to present our experience of using four minimally invasive methods in treatment of pyeloureteral stenosis by percutaneous access. Fifty patients underwent different percutaneous operative procedures: the Korth's method, endopyeloureterotomy, the Fenger's plastic, and laparoscopic dismembered pyeloplasty. We classified results into 3 groups (outcome good, outcome interm...

OBJECTIVE Dynamic renal scintigraphy complemented by late gravity assisted postvoid images to 60 minutes is a frequently used diagnostic test in the evaluation of hydrone¬phrosis. The objective of this study is to evaluate the effectiveness in acquiring images at 180 minutes to calculate the late output fraction (LOF) of 99mTc-DTPA in the diagnosis of ureteropelvic junction obstruction (UPJO). ...
