Preoperative assessment included cystovaginoscopy and magnetic resonance imaging (MRI) studies with a recording of common channel length and urethral length by each modality.<\/jats:p><jats:p>\n          Results\u2003There is substantial similarity between MRI and cystoscopy in measuring common channel length; 11 patients had common channel length 1 to 3\u2009cm by cystoscopy. It is the same number by MRI measurement. Nineteen patients had common channel length 3 to 5\u2009cm by cystoscopy and MRI. In total, 16 had urethral length &lt;1.5\u2009cm by MRI, while 14 patients with urethral length &lt;1.5\u2009cm by cystoscopy. However, there is a moderate negative correlation by MRI between common channel length and urethral length, while by cystovaginoscope, there is no significant correlation between common channel length and urethral length.<\/jats:p><jats:p>\n          Conclusion\u2003Applying MRI or cystoscopy in the preoperative assessment of cloaca cases is equivalent to measuring common channel length, not measuring urethral length. Besides that, the common channel length cannot predict the urethral length.<\/jats:p>","DOI":"10.1055\/s-0041-1725189","type":"journal-article","created":{"date-parts":[[2021,3,7]],"date-time":"2021-03-07T23:34:51Z","timestamp":1615160091000},"page":"310-315","source":"Crossref","is-referenced-by-count":4,"title":["Correlation
