BACKGROUND: Congenital hydronephrosis due to intrinsic or extrinsic
uretero-pelvic-junction (UPJ) obstruction (UPJO) is a common problem in childhood
UPJO may be caused by intrinsic disorganization or by extrinsic compression from
crossing vessels (CV); extrinsic causes usually present symptomatically in older
children. This report the large Italian experience in the treatment of children
with extrinsic-UPJO by CV. METHODS: We analyzed the data of 51 children (17 girls
and 34 boys, median age 10, 7 years) affected by extrinsic-UPJO were treated in
three Italian institutions with laparoscopic transposition of CV (Hellström
Vascular Hitch modified by Chapman).The intraoperative diuretic-test was
performed in all patients before and after the vessels transpositions confirming
the extrinsic-UPJO. We included in the study only patients with suspicion of
vascular extrinsic obstruction of the UPJ. Symptoms at presentation were
recurrent abdominal/flank pain and haematuria. All patients presented
intermittent ultrasound (US) detection of hydronephrosis (range, 18-100 mm).
Preoperative diagnostic studies included: US/doppler scan, MAG3-renogram,
functional-magnetic-resonance-urography (fMRU). RESULTS: Median operative time
was 108 minutes; median hospital stay: 3, 4 days. Unique complications: a small
abdominal wall hematoma and higher junction-translocation without obstruction.
During follow-up (range, 12-96 months) all patients reported resolution of their
symptoms, a decrease in the hydronephrosis grade and improved drainage on
diuretic renogram. CONCLUSIONS: We believe that Vascular Hitch is less
technically demanding than laparoscopic pyeloplasty, resulting in a lower
complication rate and a significantly reduced hospitalization. The results of our
study allow us to conclude that laparoscopic VH may be a safe, feasible, and
attractive alternative to treat obstructed hydronephrosis due to CV presenting a
useful alternative to AHDP in the management of symptomatic children where CV are
deemed the sole aetiology. We recommend careful patient selection based on
preoperative clinical and radiologic findings that are diagnostic of
extrinsic-UPJO, combined with intraoperative-DT to confirm the appropriate
selection of corrective procedure.
