Pathological changes in ureterovesical and ureteropelvic junction obstruction explained by fetal ureter histology.

J Pediatr Urol 2019 Feb 11. Epub 2019 Feb 11.

Department of Pathology, Sri Ramachandra Institute of Higher Education and Reseach, Porur, Chennai 600116, India.

The etiology of ureterovesical junction obstruction (UVJO) and ureteropelvic junction obstruction (UPJO) is obscure with an adynamic narrow segment causing the obstruction. In this study, the authors compared interstitial cells of Cajal (ICC) and collagen-to-muscle ratio (CM ratio) between UVJO, UPJO, and fetal ureters to investigate whether a maturational arrest of the fetal ureter could explain both clinical pathologies.

Methods: Group 1 (control) involved specimens of the normal ureter (nephrectomy for trauma/tumor; n = 20), while group 2, specimens of UVJO (n = 14); group 2 was further divided into group 2a, the dilated megaureter above UVJO, and group 2b, UVJO narrow segment; group 3, UPJO narrow segment excised during pyeloplasty (n = 31); and group 4, normal fetal ureters (n = 12).

Authors:
Philipp O Szavay

Front Pediatr 2019 11;7:29. Epub 2019 Feb 11.

Department of Pediatric Surgery, Lucerne Children's Hospital, Lucerne, Switzerland.

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. Laparoscopic surgery in pediatric urology became implemented increasingly in the twenty-first century with now present-day applications including the complete variety of all kind of indications for surgery for pediatric urological pathology. This article aims to provide a comprehensive overview of current indications, techniques, and outcomes of laparoscopic transperitoneal surgery of the upper as well as of the lower urinary tract for urological pathology in the pediatric patient population.

Laparoscopic pyeloplasty practice patterns in Canada.

Can Urol Assoc J 2019 Jan 21. Epub 2019 Jan 21.

Division of Urology, Department of Surgery, The Ottawa Hospital and University of Ottawa, Ottawa, ON, Canada.

Introduction: Ureteropelvic junction obstruction (UPJO) is a condition characterized by partial or complete obstruction of urine transport from the renal pelvis to the ureter and can present with intermittent flank pain, recurrent urinary tract infections, renal stones, or renal dysfunction. While historically, open pyeloplasty was the gold standard for surgical management, laparoscopic methods to repair UPJO have largely taken over as the preferred approach for adolescent and adult patients. Despite near universal adoption of laparoscopic pyeloplasty among Canadian urologists, it remains a technically complex procedure and considerable variability exists in the procedural steps performed.

A very easy technique of stenting for laparoscopic pyeloplasty: penbegul intravenous cannula (PICA) technique.

Int Braz J Urol 2019 Jan-Feb;45(1):179-182

Department of Urology, Dicle University School of Medicine, Diyarbakir, Turkey.

Introduction: Double-J stent insertion during laparoscopic pyeloplasty is a difficult and time-consuming process and several techniques were defined to perform a double-J stent with an antegrade approach. In this study we present the technique (PICA) of antegrade double-J placement during laparoscopic pyeloplasty by using 14 gauge intravenous cannula. Surgıcal technıque: After we complete the suturing of the posterior wall of the anastomosis during laparoscopic pyeloplasty, we first puncture the abdominal wall with a 14-gauge "intravenous cannula" from a location that provides most suitable angle for inserting the double-J stent into the ureter.

Upper Ureteric Stricture Secondary to Celiac Plexus Block Managed by Robotic Ureterocalicostomy.

J Endourol Case Rep 2018 3;4(1):183-185. Epub 2018 Nov 3.

Department of Urology, Asian Institute of Nephrology & Urology, Hyderabad, Telangana, India.

Ureterocalicostomy is a well-established procedure of choice for recurrent pelviureteric junction (PUJ) obstruction refractory to endoscopic management, failed pyeloplasty, completely intrarenal pelvis, and iatrogenic upper ureteral stricture with significant peripelvic fibrosis. Robotic ureterocalicostomy is the procedure of choice in such scenarios where meticulous dissection and accurate anastomotic suturing is required. We report the case of an 18-year-old male, who underwent celiac plexus block for pain management of chronic calcific pancreatitis and presented with pain in the epigastric region and the right flank.

Robot-Assisted Laparoscopic Reoperative Repair for Failed Pyeloplasty in Children: An Updated Series.

J Urol 2019 Jan 29. Epub 2019 Jan 29.

Department of Urology, Northwestern University, Chicago, Illinois.

Purpose: Reoperative pyeloplasty is commonly used in children with recurrent obstruction after pyeloplasty. We previously reported on reoperative robot-assisted laparoscopic repair for failed pyeloplasty in 16 children and concluded that short-term and intermediate outcomes were comparable to open reoperative repair. In this updated series we describe longer term outcomes from an extended study. Read More

Hydronephrosis severity score: an objective assessment of hydronephrosis severity in children-a preliminary report.

J Pediatr Urol 2019 Feb 11;15(1):68.e1-68.e6. Epub 2018 Oct 11.

Department of Radiology, Sri Ramachandra Medical College and Research Institute, Porur, Chennai 600116, India.

The main challenge in the management of antenatally diagnosed hydronephrosis and ureteropelvic junction obstruction (UPJO) is to differentiate the one that is likely to resolve from the pathological one. In this study, a new hydronephrosis severity score (HSS), combining ultrasonographic and renographic parameters, has been developed. Hydronephrosis severity score was analyzed with regard to its usefulness in assessing the severity of UPJO, postoperative resolution, and interobserver reliability. Read More

Redo laparoscopic pyeloplasty among children: A systematic review and meta-analysis.

Urol Ann 2018 Oct-Dec;10(4):347-353

Department of Surgery, Division of Urology, College of Medicine and King Saud University Medical City, King Saud University, Riyadh, Kingdom of Saudi Arabia.

Laparoscopic pyeloplasty (LP) is more beneficial than open procedures. However, studies on laparoscopic management of cases with secondary ureteropelvic junction obstruction (SUPJO) after previous failed pyeloplasty in the pediatric population are lacking. This meta-analysis aimed to assess the difference between redo LP (RLP) and redo open pyeloplasty (ROP) for children with SUPJO, focusing on certain criteria. Read More

Robotic surgery in pediatric urology: Current status.

Asian J Endosc Surg 2018 Nov 27;11(4):308-317. Epub 2018 Sep 27.

Department of Pediatric Urology, Nagoya City University Graduate School of Medical Sciences, Nagoya, Japan.

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 3-D view, tremor filtering, and motion scaling allow for precise intracorporeal exposure and suturing. Because most surgeries are performed as reconstructive rather than excision procedures, the robotic platform is particularly feasible for the field of pediatric urology. Read More
