“…The indication for surgery was determined on the basis of the obstruction detected on MAG3 scintigraphy, an increasing restriction of renal function by at least 5 % and a restriction of renal function to less than 43 %. Significant hydronephrosis, unilateral monstrous hydronephrosis (> 5 cm), significant (> 3 cm) bilateral hydronephrosis and a febrile urinary tract infection are also an indication for surgery [21]. All children underwent pre-and postoperative sonography of the urinary tract.…”

!Purpose: To determine the importance of MRI with contrast-enhanced MRA for the detection or exclusion of aberrant or obstructing renal arteries in ureteropelvic junction obstruction in children. Materials and Methods: Key word-based search in RIS database (ureteropelvic junction obstruction/ MRI) and retrospective comparison of arterial findings from preoperative contrast -enhanced MRA and intra-operative inspection. From 2007 to 2013, 19 children with ureteropelvic junction obstruction underwent contrast-enhanced MRA. Based on the results of the MRI scan and MAG3 scintigraphy, the children were referred to surgery (Anderson-Hynes-pyeloplasty). Results: An aberrant renal artery was diagnosed with MRI in 14 of 19 children, and intra-operative inspection confirmed 13 of those 14. In the remaining 5 children, no aberrant vessel could be observed in MRI and this was confirmed intra-operatively in 3 of the 5 cases, while in the remaining 2, an aberrant vessel was found. Of the 14 children with aberrant vessels, 12 underwent surgery due to assumed ureteral obstruction, which was confirmed by surgery in 11 cases. In one case, an aberrant artery was found intra-operatively, but obstruction could not be confirmed. In one of the 14 children, the vessel was found in MRI, but its obstructing character was negated via MRA, which was confirmed intra-operatively. In the diagnosis of aberrant and obstructing renal arteries, contrast-enhanced MRA presents 85 % sensitivity and 80 % specificity, with a positive predictive value of 0.8. Conclusion: MRI with contrast-enhanced MRA is suitable to detect aberrant and obstructing renal arteries. An obstructive effect of the aberrant vessel is to be assumed if the vessel has a close relationship to the ureteropelvic junction and if it is linearly stretched.

“…Postnatally untreated, it can cause a severe and permanent loss of renal function. Despite a still ongoing discussion about the correct follow-up and timing of surgery [4][5][6], there are a considerable number of infants under 1 year who need surgical treatment.…”

Open Pyeloplasty in Infants under 1 Year—Proven or Meaningless?

et al. 2023

The use of minimally invasive surgery (MIS) to treat ureteropelvic junction obstruction (UPJO) in children has significantly increased. Nowadays, open pyeloplasty (OP) seems to lose importance. The aim of this study is to evaluate the safety and efficacy of OP in infants < 1 year. Medical records of patients < 1 year with UPJO who had undergone retroperitoneal OP (January 2008–February 2022) at our institution were retrospectively analyzed. Included patients were operated on according to a modified Anderson–Hynes technique. All clinical, operative, and postoperative (1 month–5 years’ follow-up) data were collected. Additionally, a nonvalidated questionnaire was sent to the patients/parents. A total of 162 infants (124 boys) met the inclusion criteria. The median age at surgery was 3 months (range: 0–11 months). The median operation time was 106 min (range: 63–198 min). None of the patients had severe surgical complication (Clavien–Dindo > 3). The nonvalidated questionnaire showed a high impact of quality of life. Follow-up was in median 30.5 months (0–162 months). OP is still a reliable procedure with good long-term results especially in infants < 1 year of age, which can be performed in a variety of centers.

Abstract: This study demonstrates that conservative management is safe in children with ureteropelvic junction obstruction with no or only little constricted renal function, if a close-meshed surveillance protocol is followed and parental compliance is given.
