Double blinded prospective studv of usefulness of
bowel preparation on outpatients before intra-
venous urography
Læknablaðið 1998; 84: 829-32
Objective: The aim of this study was to examine
whether or not a bowel preparation should be ad-
ministered prior to intravenous urography (IVU) on
outpatients at the Reykjavík Hospital.
Material and methods: In a period of seven months
89 outpatients remitted to IVU were randomly divi-
ded into two groups, A and B. Patients in group A
went through bowel preparation before the investiga-
tion but patients in group B did not. The patients in
group B were asked to consume only fluids, begin-
ning the evening before the investigation. Five
patients were excluded from the study. The remai-
ning 84 patients were equally divided between
groups A and B.
Before the investigation all patients in both groups
were asked to flll out a questionnaire giving their
reactions to the preparation procedure.
Three experienced radiologists performed image
interpretation. Delineation of the urinary system,
diagnostic ability and quality of cleansing were
judged. The study was prospective and double-
blinded. The same type of contrast media, the same
dose and the same type of film were used each time.
A comparison of results between the two groups was
carried out.

Lykilorö: þarmahreinsun, skuggaefnisrannsókn af þvag-
vegum.
Results: The age distribution was the same for both
groups.
Most of the patients in group A (76%) experienced
the cleansing procedure as uncomfortable and 12%
as awful. In group B most of the patients felt the pre-
paration was comfortable. No one in group B said
that the preparation was uncomfortable.
There was no difference between the groups accor-
ding to delineation of the urinary system except for
the urinary bladder, where the delineation was jud-
ged to be worse in group B. Air in the bowel was the
main disturbing factor in group A, but both air and
faeces in group B. The quality of cleansing was jud-
ged to be better in group A. There was no difference
between the groups in terms of diagnostic ability.
Conclusions: Bowel preparation on outpatients be-
fore IVU causes discomfort to the patients and does
not improve the quality of the results.
Key words: bowel preparation, urography.
Ágrip
Tilgangur: Markmið þessarar rannsóknar
var athugun á gagnsemi þarmahreinsunar á ut-
anspítalasjúklingum fyrir skuggaefnisrann-
sóknir af þvagvegum (intravenous urography)
á myndgreiningardeild Sjúkrahúss Reykjavík-
ur.
Efniviður og aðferðir: Á sjö mánaða tímabili
var 89 sjúklingum, sem sendir voru í skugga-
efnisrannsókn af þvagvegum, skipt tilviljana-
kennt í tvo hópa, A og B. Sjúklingar í hópi A
fengu þarmahreinsun fyrir rannsóknina en þeir
í hópi B enga. Sjúklingar í þessum hópi voru
beðnir um að neyta aðeins fljótandi fæðis frá
kvöldinu fyrir rannsóknina. Fimm sjúklingar
féllu úr rannsókninni. Eftir stóðu 84 sjúklingar
sem skiptust jafnt milli hópa A og B.
Fyrir rannsóknina voru sjúklingarnir beðnir
um að fylla út spurningablöð þar sem spurt var
um óþægindi þeirra vegna undirbúningsins.
