INTRODUCTION: Laparoscopic pyeloplasty has achieved good cosmetic and functional outcomes. Both transumbilical single-site and transumbilical multi-port approaches are currently being used. No comparison of transumbilical single-site laparoscopic pyeloplasty (TSLP) and transumbilical multi-port laparoscopic pyeloplasty (TMLP) has been reported in the literature. OBJECTIVES: We present a retrospective comparison study to evaluate clinical outcomes of TSLP and TMLP for children with ureteropelvic junction obstruction (UPJO)...

Background: The use of ureteroscopy in the management of urolithiasis is well established. Ureteral avulsion is a rare but challenging complication of the procedure. Postureteral injury strictures are a common result of such injuries and are typically managed with reconstructive surgery or endoscopically with polymer stent. This case represents the first effective management of ureteral avulsion and subsequent ureteral stricture using a Memokath ureteral stent. Case Presentation: A 54-year-old gentleman presented to the Department of Urology with right loin pain as a result of right renal calculi, previously treated with extracorporeal shockwave lithotripsy...

A 76-year-old man was introduced to our department with a right kidney stone. On the basis of further examination, he was diagnosed with a 23 mm right kidney stone accompanied with a horseshoe kidney. Retrograde pyelography and diuretic renogram revealed a non-obstructed right ureteropelvic junction. Finally, we chose laparoscopic pyelolithotomy via peritoneal approach because the stone was large and accompanied with a horseshoe kidney. The surgery took 165 minutes and the estimated blood loss was 25 ml. There were no minor or major complications...

Parapelvic cysts originate in the renal parenchyma and extend into the renal sinus. A series of 3 patients with symptomatic obstructing parapelvic cysts is described, 2 with acute presentations, and 1 with chronic symptoms. In 2 of the 3 cases, there was a significant delay in establishing a diagnosis. Although one individual was successfully managed by image-guided cyst aspiration, the second patient required repeated aspiration due to cyst re-accumulation. A high index of clinical suspicion and a combination of imaging modalities, including serial ultrasound, excretory-phase CT, and MAG3 renogram, are necessary to establish the diagnosis and monitor response to treatment...

A 37-year-old woman receiving in vitro fertilisation (IVF) treatment presented with lethargy, fevers and anuria. Her background included complex surgically managed Crohn's disease and mild right-sided hydronephrosis (with no evidence of obstruction on MAG3 renogram). On examination, she had a distended abdomen with generalised tenderness. Blood tests revealed an acute kidney injury and confirmed sepsis. She was found to have bilateral ureteric obstruction with worsening of the right-sided hydronephrosis and new-onset left-sided hydronephrosis secondary to bilateral ovarian masses, diagnosed as mild ovarian hyperstimulation syndrome (OHSS)...

BACKGROUND: Congenital hydronephrosis due to intrinsic or extrinsic uretero-pelvic-junction (UPJ) obstruction (UPJO) is a common problem in childhood UPJO may be caused by intrinsic disorganization or by extrinsic compression from crossing vessels (CV); extrinsic causes usually present symptomatically in older children. This report the large Italian experience in the treatment of children with extrinsic-UPJO by CV. METHODS: We analyzed the data of 51 children (17 girls and 34 boys, median age 10, 7 years) affected by extrinsic-UPJO were treated in three Italian institutions with laparoscopic transposition of CV (Hellström Vascular Hitch modified by Chapman)...

PURPOSE: Failure after pyeloplasty for ureteropelvic junction obstruction in children may occur in up to 10% of cases. Therapeutic options include Double-J® stent placement, endoscopic treatment and reoperation. Laparoscopic and robotic reoperative modalities seem safe and efficacious, although pediatric series are limited in the literature. We report the largest known series of reoperative laparoscopic ureteropelvic junction obstruction repair in children and compare this approach to primary laparoscopic pyeloplasty...

INTRODUCTION: Paraplegic patients are at greater risk of developing complications following ureteroscopic lithotripsy because of urine infection associated with neuropathic bladder, difficulties in access due to altered anatomy of urinary bladder and urethra, spinal curvature, spasticity, and contractures. We report the occurrence of large subcapsular hematoma following ureteroscopy and discuss lessons we learn from this case. CASE REPORT: A 48-year-old male patient with spina bifida underwent ureteroscopy with laser lithotripsy and ureteric stenting for left ureteric stone and staghorn calculus with hydronephrosis; laser lithotripsy was repeated after 3 months; both procedures were performed by a senior urologist and did not result in any complications...

BACKGROUND: Radiation-induced nephropathy is still dose limiting in radionuclide therapy of neuroendocrine tumors. We investigated the nephroprotective potential of the angiotensine converting enzyme inhibiting drug enalpril after [177Lu]-DOTATATE therapy in a murine model of radiation-induced nephropathy by renal scintigraphy. At first, the appropriate therapy activity to induce nephropathy was identified. Baseline scintigraphy (n = 12) entailed 12-min dynamic acquisitions after injection of 25 MBq [99mTc]-MAG3, which was followed by radionuclide therapy at four escalating activities of [177Lu]-DOTATATE: group (Gp) 1: 10 MBq; Gp 2: 20 MBq; Gp 3: 40 MBq; Gp 4: 65 MBq...
