| Summary: | Introduction: Most common carcinomas of lower urinary tract
are of urothelial type in which, majority of them occur in the
bladder. The demonstration of exfoliated neoplastic cells in
urine sediment cytology is one of the choices of investigation.
Aim: To study the morphology of atypical cells of urine sediment
in unstained wet mount preparation and urine sediment obtained
by cytospin smear stained with Papanicolaou stain.
Materials and Methods: It was a descriptive observational
study done over a period of 29 months i.e., from July 2016
to December 2018 at SS Institute of Medical Sciences and
Research Centre, Davangere, Karnataka, India. Using non
probability sampling method, 50 urine samples were analysed
by DIRUI-H 500 a semi automatic urine analyser, which were
further examined by wet mount preparation and cytospin smear
stained with papanicolaou stain. Results were analysed by
whether the smears were positive or negative for atypical cells
based on the cytological and nuclear details.
Results: The yield of Red Blood Corpuscles (RBCs) was
significantly increased in cytospin preparation with morphology
of RBCs was better appreciated in wet mount compared to
cytospin preparation. The yield of atypical cells was significantly
increased in cytospin preparation with the morphology of
atypical cells were better appreciated in pap stained cytospin
preparation compared to wet mount urine examination.
Conclusion: Overall, cell yield and preservation of White Blood
Corpuscles (WBCs), epithelial cell and atypical cells morphology
was better in cytospin preparation, while RBCs were better
appreciated in wet mount preparation. Cytospin technology is
a quick, efficient and cost effective method for increasing cell
yield in less cellular samples and also helps in providing better
cellular morphological details. |
