Diuresis renography was performed in 37 patients (41 kidneys) who had equivocal pelviureteric junction obstruction. The non-obstructive pattern (Type 1 and 3a) was observed in 26 cases, the obstructive pattern (Type 2) in 7 cases and partial obstruction (Type 3b) in 8 cases. None of the cases with a type 1 response worsened, while all the cases with a type 2 response were found to have pelviureteric junction obstruction. Cases with a type 3a response needed no surgery-except one who worsened to type 3b, another who had calculi and one with persistently severe symptoms. 50 per cent of the type 3b response group required surgery. The diuresis renogram is a simple, safe, accurate and non-invasive method of investigation in cases of equivocal pelviureteric junction obstruction. The recommendations are- no surgery for response 1, pyeloplasty for response 2, follow up for type 3a and 3b and surgery if complications arise.
