Robotic upper urinary tract reconstruction (UUTR) has been widely utilized for surgical management of congenital obstruction. To further reduce morbidity and simplify postoperative care, outpatient robotic pyeloplasty (RP) and robotic ureteroureterostomy (RUU) were performed without ureteral stents, drains, or urethral catheters. The aim of the study was to assess the safety of performing tubeless robotic UUTR as an outpatient procedure. A retrospective review was performed for patients who underwent outpatient tubeless RP and RUU between July 2015 and January 2017...

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)...

OBJECTIVE: To report our experience on gas endoscopy as the first step of pelvi-ureteric junction (PUJ) obstruction repair when complicated by nephrolithiasis. MATERIALS AND METHODS: Stone formation due to urine stasis is a known complication PUJ obstruction and an indication for its surgical repair. The undisputed results of the Anderson-Hynes dismembered pyeloplasty make it a quasi-gold standard; however, the identification and extraction of calyceal stones through the laparoscopic route can be challenging...

OBJECTIVES: Uretero-pelvic junction (UPJ) obstruction has been classically treated by open dismembered pyeloplasty. Recently, laparoscopic (LP) and robotic pyeloplasty (RP) have become the techniques of choice for the treatment of UPJ stenosis in adult and pediatric population. Our objective in this paper is to review the results of minimally invasive surgery as the treatment of UPJ obstruction, the trend to use these approaches and the current limits of LP and RP. METHODS: A review of most relevant papers and meta-analysis about LP and RP in pediatric and adult population was performed using PubMed...

BACKGROUND: MAG3 diuretic renal scan remains the gold standard for determination of improvement in renal drainage following pyeloplasty for ureteropelvic junction obstruction. We hypothesized that (i) a change in geometric measurements between pre-operative and post-operative renal ultrasound (RUS) images and (ii) blinded simple visual review of images both would predict pyeloplasty success. OBJECTIVE: To determine if simple visual review and/or novel geometric measurement of renal ultrasounds can detect pyeloplasty failure...

BACKGROUND: Genitourinary tuberculosis still continues to plague developing countries and is a significant cause of morbidity as well as mortality in the developing world. At present, nearly 55% of the patients of genitourinary tuberculosis (GUTB) need surgical management. Owing to the presence of dense adhesions and loss of normal anatomical planes, GUTB was considered to be a contraindication to laparoscopic surgery. However, recent literature shows laparoscopy to be feasible in GUTB...

INTRODUCTION: Laparoscopic pyeloplasty in children has stood the test of time. A clear advantage of laparoscopic pyeloplasty over open pyeloplasty has been proven both by retrospective and prospective trials. The aim of the current study was to address, in a prospective design, the outcomes, safety, conversion rates and risk factors for conversion in children aged <2 years who underwent retroperitonoscopic pyeloplasty by a single surgeon. PATIENTS AND METHODS: In the period April 2014 to May 2016, 15 children with a median age of 6 months (range 1-24) and ureteropelvic junction (UPJ) obstruction were operated by a single surgeon using retroperitonoscopic pyeloplasty with antegrade renal stenting...

Giant hydronephrosis (GH) is a condition in which pelvicalyceal system contains more than 1000 ml of urine. Common causes of GH are uretero-pelvic junction obstruction, renal calculus, abdominal trauma. We are reporting a case of 45 years' male, who presented with abdominal trauma and haematuria and was suspected a urinoma secondary to renal trauma. Examination revealed soft, cystic abdominal lump. Computed tomography of the abdomen revealed grossly hydronephrotic right kidney. The patient was managed by pyeloplasty after renal scan (estimated plasma renal flow- 91...
