99m Tc diethylenetriaminepentaacetic acid (DTPA) renogram is a commonly performed evaluation postrenal transplant to assess graft function and for early detection of suspected immediate and late transplant-associated complications. Although several modalities can be utilized to detect perinephric collection in posttransplant period, the utility of 99m Tc DTPA single-photon emission-computed tomography (SPECT-CT) is not recognized. Herein, we discuss the incremental role of seldom considered SPECT-CT in early detection, leading to timely appropriate management and graft salvage in a case of posttransplant deteriorating renal allograft as a result of subcapsular hematoma...

Horseshoe kidney (HSK) is a congenital defect of the urinary tract that occurs in 0.25% of the general population. Laparoscopic Vascular Hitch (LVH) according to Hellstrom-Chapman represent an alternative approach in treatment of extrinsic hydronephrosis by crossing vessels (CV) in pediatric age. In our Department from 2006 to 2016, 36 children with extrinsic-Uretero-Pelvic-Junction (UPJ)-Obstruction (UPJO) underwent laparoscopic vessels transposition. Over the last 4years, we have treated three patients with extrinsic hydronephrosis in HSK; two males and one female respectively of 6, 7 and 8years...

Ectopic thoracic kidney is an extremely rare condition caused by the abnormal location of one or both kidneys in the thoracic cavity. They are usually discovered incidentally on routine imaging. Although commonly asymptomatic, thoracic kidneys are at a risk of malrotation, pelviureteric junction obstruction, and subsequent obstructive nephropathy, by virtue of their long pedicle. We present a case report of an incidental thoracic kidney, for which a99m technetium-mercaptoacetyltriglycine (99m Tc-MAG3) renogram was performed to assess the baseline renal function...

A 26-year-old woman presented to our hospital with right costovertebral angle (CVA) pain. Ultrasonographyand computed tomography(CT) scan indicated right hydronephrosis, and MAG3 renogram showed an obstructed pattern in the right kidney. Enhanced CT scan revealed an ureteropelvic junction obstruction (UPJO) with an aberrant vessel. To clarifythe ureteropelvic junction (UPJ) structure in detail, we utilized 3D-CT with retrograde pyelography (RP), which further revealed the true pinhole ureteral stricture of UPJ unaffected bythe aberrant vessel...

INTRODUCTION: Intraoperative warm ischemic time (WIT), associated with hilar clamping during partial nephrectomy (PN), is an established modifiable risk factor for renal dysfunction. We assessed early clamp release (ECR) as a strategy to reduce WIT and assess its impact on renal function and bleeding. METHODS: We retrospectively assessed patients who underwent minimally invasive PN by a single surgeon at our centre since December 2011. Comparing the standard technique to an ECR modification, WIT, complications, change in estimated glomerular filtration rate (eGFR), and change in differential function as demonstrated by MAG-3 nuclear renography were assessed...
