Pyeloplasty Articles

We compared the outcomes in patients who were <1 year old and had hydronephrosis with SFU grade 3-4 PUJ obstruction to observe the potential recovery of renal morphology and DRF after successful pyeloplasty.

Application of laparoscopy in pediatric urology has evolved over more than 30 years coming from a merely diagnostic use for non-palpable testes to "interventional" laparoscopy to extirpative surgery and finally to the era of reconstructive pediatric laparoscopic urology, when in 1995 Peters described the first laparoscopic pyeloplasty in a child.

SAN DIEGO, CA USA (UroToday.com) - Several training systems simulating surgical procedures are commercially available, but none of them accurately represent patient-specific anatomy.

Robotic surgery in pediatric urology has been gaining popularity since its introduction almost two decades ago. Robotic assisted pyeloplasty is the most common robotic procedure performed in pediatric urology.

Robot-assisted laparoscopic surgery (RALS) has been increasingly embraced in the fields of adult and pediatric urology, especially in North America and Europe. The advantages of a stable magnified three-dimensional view, tremor filtering, and motion scaling allow for precise intracorporeal exposure and suturing.

Hydronephrosis is the one of the most common congenital abnormalities of urinary tract. The left kidney is more commonly affected than the right side and is more common in males.

To determine the role of ultrasonography, renal dynamic scintigraphy and lowerdose computed tomography urography in preoperative diagnostic workup of infant with extreme hydronephrosis.

Robotic pyeloplasty has become more prevalent with the evolution and dissemination of robotic surgery. The da Vinci SP robotic platform is a new technology that has allowed for true single port surgery, compared to the previous multiport robotic platforms.

A pelvic kidney occurs in between 1 in 2,200 and 1 in 3,000 people1, due to failure of ascent during development. It is commonly asymptomatic and usually functions normally. Pelvic ureteral junction obstruction (PUJO) can either be congenital or acquired, and is characterised by intrinsic stenosis or extrinsic compression of the ureter at the junction with the pelvicalyceal renal system.

The aim of the study was to assess the feasibility and outcomes of pediatric urological laparoendoscopic single-site (LESS) surgery.

We retrospectively collected charts of all patients who underwent LESS procedures in our department from January 2013 to December 2016.

The aim of this randomized controlled trial (RCT) is to compare the outcomes of conventional laparoscopic pyeloplasty (LP) versus robotic-assisted laparoscopic pyeloplasty (RALP) in the treatment of ureteropelvic junction obstruction (UPJO) in children.

It has been suggested that up to 40 cases of RALP are required to reach the operative results equal to open surgery. We have hypothesized that previous experience in open and laparoscopic surgeries might shorten the learning curve of robotic surgery.

The use of ureteric stents for urinary diversion after pediatric dismembered pyeloplasty and its duration remain debatable. Classically, an indwelling Double J ureteric stent has to be left for 4-6 weeks.

This study was performed to analyze the predictive factors of a contralateral operation after initial pyeloplasty in patients with antenatally detected bilateral ureteropelvic junction obstruction.

Patients with prenatally diagnosed bilateral ureteropelvic junction obstruction who underwent initial pyeloplasty (aged <12 months at initial pyeloplasty) were offered to participate in the study.

This multicentric study aimed to report our experience with robot-assisted laparoscopic pyeloplasty (RALP) in children with horseshoe kidney (HSK).

The records of 14 patients (11 boys and 3 girls with an average age of 9 years), who underwent RALP for repair of pelvi-ureteric junction obstruction (PUJO) in HSK in five international pediatric urology units over a 5-year period, were retrospectively reviewed.

The da Vinci SP® Robotic Surgical Platform (Intuitive Surgical) was recently introduced to overcome triangulation and motion restriction during laparoendoscopic single-site surgery. The authors describe a pure, single-site, robot-assisted, laparoscopic pyeloplasty (RALP) using the da Vinci SP System in a pediatric patient.

This study aimed to report a multi-institutional experience with robot-assisted laparoscopic surgery (RALS) for treatment of urinary tract stones in children. The medical records of 15 patients (12 boys), who underwent RALS for urolithiasis in 4 international centers of pediatric urology over a 5-year period, were retrospectively collected.

Although both laparoscopic pyeloplasty (LP) and robot-assisted laparoscopic pyeloplasty (RALP) have reported excellent clinical outcomes, no evidence is currently available about the best surgical approach for surgical treatment of children with uretero-pelvic junction obstruction (UPJO).

The popularity of robot-assisted surgeries has accelerated since its advent in 1990s. Recently, we procured da Vinci surgical system in our institution; and here, we present our initial experience of robot-assisted surgeries at our hospital.

Single port (SP) robotic assisted laparoscopic surgery was approved by the FDA for urologic surgery and clinically available in 2018. This new robotic system enables a camera and 3 separate instruments, with fully wristed motions, to be placed through a single 25 mm port.

Since the introduction of the Da Vinci Surgical System (Intuitive Surgical, Inc., Sunnyvale, CA) in 1999, the market for robot assisted laparoscopic surgery has grown with urology. The initial surgical advantage seen in adults was for robotic prostatectomy, and over time this expanded to the pediatric population with robotic pyeloplasty.

To evaluate how variations in peri-operative urine culture (UCx) and antibiotic prophylaxis utilization following robot assisted laparoscopic pyeloplasty (RALP) affect post-RALP urinary tract infection (UTI) rates in children, then use data to generate a standardized care pathway.
