What is Pelvi-ureteric Junction Obstruction by Crossing Renal Vessels: Clinical and Imaging Features about?

## OBJECTIVE To present the characteristic clinical and imaging findings of pelvi‐ureteric junction (PUJ) obstruction caused by crossing renal vessels (CRV), as it presents particular features within the spectrum of congenital hydronephrosis. ## PATIENTS AND METHODS Between April 1982 and December 2000, 384 children underwent surgery for PUJ obstruction. In 71 (18.5%; mean age 8.5 years, range 2 months to 14 years; 49 aged> 5 years), the obstruction was caused by CRV. The data collected from the medical records of these patients were analysed for their clinical presentation and imaging findings, i.e. ultrasonography (US), intravenous urography (IVU) and diuretic renography. ## RESULTS The main presenting symptom was recurrent renal colic (pain, nausea, vomiting) in 59%, followed by urinary infection (UTI) in 20%, gross haematuria in 11% and an incidental diagnosis in 10%. By contrast, in the 313 children with intrinsic PUJ obstruction, renal colic was present in only 10.5%. Moreover, from 1991 to 2000, when the use of prenatal US became widespread, hydronephrosis was detected prenatally in 42 of 212 children (20%) with intrinsic PUJ obstruction, but in only two of 31 (6%) with obs
