Purpose: This study investigated the sensations reported during filling cystometry in patients with spinal cord lesions (SCLs) of different levels and completeness. Methods: In this retrospective cohort study, information was gathered on patients’ age and sex, cause of SCL, American Spinal Injury Association Impairment Scale (AIS), and lower urinary tract-related sensations in daily life. Filling cystometry (videourodynamics) was performed following the International Continence Society Good Urodynamic Practice Guidelines. In addition to bladder filling sensations (first sensation of bladder filling, first desire to void, strong desire to void), other sensations, such as detrusor overactivity related sensation and pain, were noted. Results: In total, 170 patients were included (age, 45±17 years; 114 males and 56 females, 92 with complete and 78 with incomplete SCL). The test was done 6±4 years post-SCL. Sensation was reported by 57% of all patients. Half of the patients with complete SCL (46 of 92) had sensation, while 36% of those with incomplete SCL (28 of 78) reported no sensation. Bladder awareness was not predictable by the AIS. The filling sensations reported were equivalent to those given in the terminology of ICS. Pain was seldom present (6%, 10 of 170), and detrusor overactivity contraction was felt by 45 of 78 (58%). Very few patients used sensory information for bladder management at home. Conclusions After SCL, most patients retained the ability to be aware of the lower urinary tract, and were assessable and gradable during urodynamic testing. The filling sensations were not different from those described in healthy individuals, but the number and sequence of the sensations were altered in a minority of patients. Pain and a sensation of unstable contractions gave additional important information. As different sensations relate to different spinal afferent pathways, the sensory evaluation during cystometry provided additional important information on the spinal cord’s condition.

AIMTo investigate whether urine is a good medium for screening and whether there is a correlation between the amount of extracted DNA and human papillomavirus (HPV)-positivity.

METHODSIn the present study, 30 first-voided urine (FVU) specimens and 20 urethroglandular swabs using cervex-brushes from male partners of HPV-positive patients, and 31 FVU specimens and 100 liquid-based cervix cytology leftovers sampled with cervix-brushes from HPV-positive women were examined for the presence of beta-globin. Oncogenic HPV were detected using type-specific PCR.

RESULTSbeta-globin was found in all the brushed samples, whereas it was found in only 68.9% of the FVU specimens. HPV-PCR was positive in 60.0% of the male brushes, in 29% of the female brushes and in 0% of the male FVU specimens. DNA concentration was, respectively, 0.9998 ng/microL, 37.0598 ng/microL and 0.0207 ng/microL.

CONCLUSIONUrine is not a good tool for HPV detection, probably because the low DNA concentration reflects a low amount of collected cells. beta-globin is measurable in FVU by real time quantitative PCR, but the DNA concentration is lower compared to brush sampling for both genders. beta-globin-positivity of urethral and cervical swabs is 100%, showing a higher mean concentration of DNA, leading to a higher detection rate of HPV. This is the first article linking DNA-concentration to the presence of HPV.
