Purpose: First, to assess the number of patients with anorectal malformations (ARM) in whom additional urological and/or gynecological anomalies were identified through routine screening with cysto- or vaginoscopy prior to reconstructive surgery. Second, to assess potential procedure-related complications.

Methods: Retrospective mono-center cohort study, including all ARM patients born between January 2019 and December 2022.

Article Synopsis
  • The study aimed to evaluate the occurrence of spinal cord anomalies, particularly tethered spinal cord, in patients with anorectal malformations using spinal cord imaging methods.
  • A total of 254 patients were analyzed, with 234 (92.1%) receiving spinal cord imaging, revealing that 22.2% had a spinal cord anomaly.
  • The findings suggest that screening for spinal cord anomalies is essential for all patients with anorectal malformations, regardless of their condition's complexity.

To evaluate fertility potential after orchidopexy for bilateral undescended testis and compare two surgical fixation techniques for effect on fertility. Men older than 22 years who had either tunica albuginea orchidopexy (TAO) or "no-touch" technique (NTO) in childhood for bilateral undescended testis (BUDT) were selected. Participants filled out a questionnaire followed by physical examination, had testicular ultrasound, blood sample and semen analysis.

Objective: To investigate whether children with lower urinary tract (LUT) anomalies are at greater risk for postoperative complications after laparoscopic pyeloplasty stented with a double-J catheter (JJC).

Materials And Methods: Prospectively collected data of laparoscopic pyeloplasty (LP) performed between 2006 and 2015 were analyzed. Inclusion criteria are (1) toilet-trained child and (2) unilateral dismembered pyeloplasty stented with a JJC done by the same surgeon.

Introduction: Candida bezoar (CB) is a rare finding in neonates and infants with candiduria, presenting as necrotic debris with proliferating mycelia in the collecting system of the kidney. If initial antifungal medical treatment does not result in clearance of candiduria and disappearance of CB on ultrasound in dilated kidneys, invasive interventions like insertion of nephrostomy tubes (NT) or surgical interventions to drain the kidney are sometimes advocated(.).

Purpose: A duplex collecting system is a common congenital renal tract abnormality associated with different clinical problems. We describe our experience with ureteral reimplantations of a complete duplex collecting system where 1 megaureter needing recalibration and 1 normal-sized ureter coexisted. Recalibration of the megaureter was done by wrap plication around the normal-sized ureter.
