The coexistence of ureteropelvic junction obstruction and reflux

Volume Related Configurational Changes in The Aetiology of Pelvi‐Ureteric Junction Obstruction

“…1989 J. DE CAMPO, R. FOWLER The co-existence of VUR with P U J obstruction has generally been discounted as being mere coincidence (Lebowitz & Blickman 1983) but the tortuosity present at the PUJ in many children with moderate or severe vesico-ureteric reflux (and two of our cases) may provide the anatomical setting for PUJ obstruction to develop either intermittently or dJring a diuresis. In addition obstruction may be precipitated after the renal pelvis has been maximally distended by an episode of reflux.…”

Familial Pelviureteric Junction Hydronephrosis and its Association with a Duplex Pelvicaliceal System and Vesicoureteric Reflux. A Family Study

“…The incidence of vesicoureteric reflux in patients with PUJ hydronephrosis varies between 10 and 20%. This clinical association of the two defects is well known but has not often been reported (Lebowitz and Blickman, 1983;Maizels et al, 1984). I t is important to differentiate between the two types of hydronephrosis associated with reflux, the first without evidence of obstruction on intravenous urography (reflux-induced hydronephrosis) and the second with obstruction at the pelviureteric junction.…”

Coexisting Ureteropelvic Junction Obstruction and Ureterovesical Junction Obstruction: Is Pyeloplasty Always the Preferred Initial Surgery?

“…In cases of secondary UPJO caused by VUR, initial pyeloplasty has been suggested to be a better initial management modality than the correction of VUR. 23 However, a recent report by Ebadi et al 24 demonstrated resolution of UPJO after endoureterotomy for distal UVJO. In our study, only 2 of 5 patients with initial UNC required additional pyeloplasty.…”
