Abstract

Aims:

Uroflowmetry is a
simple, noninvasive, easy to use and objectively interpretable urodynamic
study. Uretral stenosis is the most common late complication after hypospadias
surgery. The aim of this study was to evaluate the possible postoperative
meatal stenosis in patients who were operated for hypospadias in our clinic
with uroflowmetry.

Material
and Methods:

The patients with
hypospadias operated in our clinic between January 2015 and January 2017 were
determined as our study group.Uroflowmetry and urine flow measurements were
performed at least two months after the operation. After uroflowmetry
measurement, the residual urine volume was measured by ultrasound device in
pediatric surgery clinic. The estimated bladder volumes were calculated
according to the age of the patients.

Results:

The median age of the
patients was 7.5 (3-14). In the postoperative period, 9 (19.5%) of the patients
had complaints of narrow urination and urination as a clinical complaint. No
statistically significant difference was found between the two groups in terms
of uroflowmetry results, maximum flow rate, time to reach maximum flow rate,
total urine flow time, mean flow rate and residual urine volume (p> 0.005).Sixteen
patients (25.4%) in the postoperative group were smaller than <-2SD
according to the Siroky nomogram and were in the obstruction group.

Conclusions:

Uroflowmetry is an
easy-to-use noninvasive test used to assess early obstruction and to diagnose a
urethral stricture following hypospadias surgery. When compared with the
literature, the maximum flow rate in uroflowmetry measurements is less than 10
ml / s, the average flow rate is low, the voiding curve is the plateau curve and
the five-percentile according to the nomograms and the voiding curve smaller
than -2 SD results are evaluated in terms of urethral obstruction and urethral
dilatation planning is important.

Hipospadias Cerrahisi Sonrası Üretral Darlığın Üroflowmetri İle Değerlendirilmesi

Abstract

Bu
çalışmanın amacı hipospadiaslı olgularda eşlik edebilecek alt üriner sistem
obstruksiyonunu üroflowmetri ile değerlendirmek ve bu durumun klinik önemini
vurgulamaktır. Kliniğimizde Ocak 2012 - Ocak 2013 tarihleri arasında takip ve
tedavisi yapılan hipospadiaslı olguların idrarını tutabilen yaş grubunda olan
ve ailesinin işleme yazılı onam verdiği 63 hastaya, ameliyat öncesi poliklinik
değerlendirmede ve ameliyat sonrası dönemde eşlik eden alt üriner sistem
obstruksiyonu değerlendirmek için üroflowmetri ile idrar akış ölçümleri
yapıldı.Tüm hastaların işeme akım eğrisi paternleri tek tek incelendi.
Literatüre uygun olarak azami akış hızı, ortalama akış hızı, azami akışa ulaşma
süresi, idrar akış süresi, idrar boşaltma süresi, işeme sonrası rezidü idrar miktarı
ve işeme eğrisi özelliği ameliyat öncesi ve ameliyat sonrası yapılan
üroflowmetri test sonuçları ile karşılaştırıldı.Üroflowmetrinin orta ve uzun
vadede hipospadias cerrahisi açısından üretral stenozun ve eşlik eden alt
üriner sistem obstruksiyonun erken tanınmasında önemli, ucuz, kolay
uygulanabilen non invaziv bir test oldugu düşünülmektedir.
