Summary
Introduction
Previously in our unit, urodynamics were delayed after insertion of suprapubic (SP)
lines. We postulated that performing urodynamics on the same day as SP line insertion
would not result in increased morbidity. We retrospectively compared complications
in those having urodynamics on the same day against those who had delayed urodynamics.
Patients and methods
Notes were reviewed for patients undergoing urodynamics via SP lines from May 2009
until December 2018. In 2014 we modified our practice to allow urodynamics on the
same day as SP line insertion in some patients. Patients undergoing videourodynamics
would have two 5 Fr (mini Paed) SP lines inserted under general anaesthesia. Patients
were divided into two groups: those that had urodynamics on the same day as SP line
insertion and those that had urodynamics after an interval of more than one day. The
outcome measure was the number of problems affecting those in each group. The two
groups were compared using Mann–Whitney U tests and Fisher's Exact tests.
Results
There were a total of 211 patients with a median age of 6.5 years (range three months
to 15.9 years). Urodynamics were performed on the same day in 86. Delayed Urodynamics
were performed at an interval of more than one day in 125. Adverse events included
pain or difficulty with voiding, increased urinary frequency, urinary incontinence,
leak from catheter site, extravasation, extension of in-patient stay, visible haematuria,
urethral catheterisation, and urinary tract infection. Problems affected 43 (20.4%)
children. In the same day group, 11 (13.3%) patients had problems, in the delayed
group 32 (25.6%) had problems; this was statistically significant (p = 0.03). The
difference in combined incidence of important problems (requiring urethral catheterisation,
extended admission or abandonment of urodynamics) was not statistically significant
between the two groups.
Conclusion
When using suprapubic catheters for urodynamics there is no additional morbidity when
catheters are inserted on the same day as the urodynamics study compared to when urodynamic
are delayed.
