Lumboscopic-Assisted Pyeloplasty: A Single-Port, Retroperitoneoscopic Approach for Children with Pelvi-Ureteric Junction Obstruction.

J Indian Assoc Pediatr Surg 2020 May-Jun;25(3):163-168. Epub 2020 Apr 11.

Department of Anaesthesia, All India Institute of Medical Sciences, New Delhi, India.

Introduction: Pelvi-ureteric junction obstruction (PUJO) is one of the most common conditions presenting to a pediatric urologist. As laparoscopic or robotic-assisted pyeloplasty, either transperitoneal or retroperitoneal, involves intracorporeal suturing skills and has a long learning curve, they have not gained popularity among beginners in laparoscopy.

Managing Ureteropelvic Junction Obstruction in the Young Infant.

Front Pediatr 2020 27;8:242. Epub 2020 May 27.

University of Texas Southwestern Medical Center, Dallas, TX, United States.

In the last decade, management of congenital UPJ obstruction has become progressively observational despite the lack of precise predictors of outcome. While it is clear that many children will have resolution of their hydronephrosis and healthy kidneys, it is equally clear that there are those in whom renal functional development is at risk. Surgical intervention for the young infant, under 6 months, has become relatively infrequent, yet can be necessary and poses unique challenges. Read More

Use of retrograde pyelogram to plan for miniature open incision in pediatric pyeloplasty.

J Pediatr Urol 2020 Apr 30. Epub 2020 Apr 30.

Division of Pediatric Urology, Riley Hospital for Children at IU Health, 705 Riley Hospital Dr., Suite 4230, Indianapolis, IN, 46202, USA. Electronic address:

Introduction: As robotic-assisted surgery becomes increasingly utilized for pediatric ureteropelvic junction (UPJ) obstruction, open surgeons have countered by using muscle-splitting, miniature (≤2 cm) incisions. To prepare for this type of incision during pyeloplasty, it is necessary to define the exact location of the UPJ. The use of retrograde pyelogram (RPG) at the time of pyeloplasty helps the surgeon to identify the exact location of UPJ, and thus be able to use a muscle-splitting, miniature incision for open pyeloplasty.

Learning curve of robotic-assisted laparoscopic pyeloplasty (RALP) in children: how to reach a level of excellence?

J Robot Surg 2020 Apr 24. Epub 2020 Apr 24.

The Department of Pediatric Urology, Shaare Zedek Medical Center, The Faculty of the Medicine, The Hebrew University, P.o.B 3235, 91031, Jerusalem, Israel.

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. We have retrospectively evaluated the data of all children who underwent pyeloplasty in our institute by a single surgeon since 2003. Read More

Impact of successful pediatric ureteropelvic junction obstruction surgery on urinary HIP/PAP and BD-1 levels.

J Pediatr Urol 2020 Mar 29. Epub 2020 Mar 29.

Division of Pediatric Urology, Department of Pediatric Surgery, Nationwide Children's Hospital, Columbus, OH, USA; Abigail Wexner Research Institute at Nationwide Children's Hospital, Columbus, OH, USA. Electronic address:

Introduction: In the pediatric patient whose ureteropelvic junction obstruction (UPJO) is not always symptomatic, imaging is the most common means of detecting surgical success. There is interest, however, in other means of post-operative monitoring. A panel of antimicrobial peptides (AMPs) has been previously found to be elevated in UPJO, but the impact of surgical correction on these AMPs is unknown. Read More

Cortical transit time: understanding utility and pitfalls in children with pelviureteric junction obstruction.

J Pediatr Urol 2020 Jun 19;16(3):330.e1-330.e6. Epub 2020 Feb 19.

Department of Pediatric Surgey, All India Institute of Medical Sciences, Ansari Nagar, New Delhi 110029, India.

Introduction: Delayed cortical transit time (CTT) has been recently studied and proposed as a parameter that can predict the need for surgery in children with pelviureteric junction obstruction (PUJO).

Aim: The aim of this study was to study the change in CTT, after surgery, in children with PUJO and to correlate CTT with intrapelvic pressure of the kidney.

Material And Methods: A prospective study was performed, and all children who underwent pyeloplasty from January 2016 to December 2017 were included. Read More

Robotic dismembered pyeloplasty surgical simulation using a 3D-printed silicone-based model: development, face validation and crowdsourced learning outcomes assessment.

J Robot Surg 2020 Apr 2. Epub 2020 Apr 2.

Boston Medical Center, Boston University School of Medicine, 725 Albany St., Suite 3B, Boston, MA, 02118, USA.

Ureteropelvic junction obstruction (UPJO) is an uncommonly encountered pathology, posing a challenge for resident training. We describe the development and face validation of a robotic pyeloplasty simulation using a 3D-printed silicone-based model of UPJO for surgical training, in combination with crowdsourced scoring to objectively assess performance and learning outcomes. The organs were created using 3D modeling software and printed using a silicone-based material by Lazarus 3D, LLC. Read More

[Uretero-pelvic junction obstruction due to crossing pole vessel: contra vascular hitch].

Aktuelle Urol 2020 Apr 24;51(2):121-126. Epub 2020 Mar 24.

Cantonal Hospital Lucerne Children's Hospital, Pediatric Surgery, Luzern.

Hydronephrosis in infants and children is most commonly due to a congenital, intrinsic obstruction of the uretero-pelvic junction. The Gold standard of care is defined as a dismembered pyeloplasty, nowadays mostly performed in a minimally-invasive procedure, either through a laparoscopic (also robotic-assisted) or retroperitoneoscopic approach. Less common is an extrinsic obstruction of the ureter or the uretero-pelvic junction caused by an aberrant crossing pole vessel, a condition more likely to affect children beyond infancy. Read More

[Surgical learning curve for top-down two-knot laparoscopic pyeloplasty in congenital hydronephrosis in children].

Urologiia 2020 Mar(1):86-90

Speranskij Childrens Municipal Hospital 9, Moscow, Russia.

The aim was to evaluate the surgical learning curve and advantages of top-dow two-knot laparoscopic pyeloplasty in children with uretero-pelvic junction obstruction (UPJO).

Materials And Methods: A retrospective analysis of medical records regarding 98 patients from Speranskij Childrens Municipal Hospital No9, Moscow and Regional Clinical Hospital No7, Volgograd, aged from 3 to 24 months with unilateral hydronephrosis of varying degrees, according to the SFU classification (Society of Fetal Urology) in the Onen modification was carried out. LP in all children was performed in accordance with the Heins-Andersen technique, with minimal resection of the pelvis. Read More

University of Texas Southwestern Medical School, Dallas, TX, USA. Electronic address:

Introduction/background: Owing to restrictions in operative experiences, urology residents can no longer solely rely on 'hands-on' operative time to master their surgical skills by the end of residency. Simulation training could help residents master basic surgical skills and steps of a procedure to maximize time in the operative room. However, simulators can be expensive or tedious to set up, limiting the availability to residents and training programs. Read More

Lenox Hill Hospital (Northwell Health), 170 E 77th Street, Suite B, New York, NY, 10075.

Urologists have always been leaders in advancing surgical technology and were the first to utilize modern robotic surgery for robotic-assisted laparoscopic radical proctectomy. Surgeon ergonomics, instrument precision, operative time, and postoperative recovery were all objectively improved. In urology, robotic surgery is now used for all intra-abdominal, retroperitoneal, and pelvic procedures and has been expanded to renal transplants and pediatric use. Read More

John Radcliffe Hospital, Oxford, UK.

A 5-year-old girl underwent an elective left pyeloplasty for pelvoureteric junction obstruction (PUJO). At laparoscopy, two ureters were seen to be draining a left duplex kidney, with a PUJO of the lower moiety. Interestingly, however, the upper moiety ureter was bifurcating to drain both upper and lower moiety as well. Read More
