Interstitial Cells of Cajal and PX Receptors at Ureteropelvic Junction Obstruction and Their Relationship with Pain Response.

: Etiopathogenesis and the symptomatology of ureteropelvic junction obstruction (UPJO) in the pediatric population has not yet been definitely clarified, suggesting a multifactorial nature of the condition. The aim was to analyze the association between the number of Interstitial Cells of Cajal (ICCs), as well as PX receptors in ureteropelvic junction (UPJ) and the pain response in pediatric patients with hydronephrosis. 50 patients with congenital hydronephrosis underwent open or laparoscopic pyeloplasty at one of two departments of pediatric surgery and urology in Poland.

Preserved Voluntary Micturition Control despite Early Urinary Diversion in Infancy-A Clue to a New Strategy.

Micturition is an involuntary process based on spinal arcs in infants and children until a defined age. The awareness and voluntary control of voiding depends on specific areas in the central nervous system, especially cortical regions. The cells and connections between these areas develop over time and regulate the voiding process.

Laparoscopic Heminephrectomy for Duplex Kidney in Children-The Learning Curve.

Outcomes evolution during the learning curve of laparoscopic transperitoneal heminephrectomy in children with a duplex kidney. The data of 33 children, operated on between 2008 and 2017, with complicated duplex kidney, were subjected to a retrospective analysis. All patients were operated on by transperitoneal access using the laparoscopic technique.

Laparoscopic versus open pyeloplasty in children: experience of 226 cases at one centre.

Introduction: The aim of the study was to compare the efficacy of laparoscopic versus open dismembered pyeloplasty in children.

Material And Methods: Two hundred and twenty-six Anderson-Hynes pyeloplasties were performed, out of which 131 by open access (OP) and 95 by laparoscopic access (LP). Retrospective analysis of data was performed.

Hydronephrosis in Children Caused by Lower Pole Crossing Vessels-How to Choose the Proper Method of Treatment?

Assessment of the efficacy of intraoperative diagnosis between extrinsic and intrinsic UPJO in children. Assessment of the efficacy of laparoscopic vascular-hitch procedure in UPJO caused by lower pole crossing vessels (CV). Between 2008 and 2017, 47 laparoscopic procedures were performed with the CV discovered intraoperatively.
