Value of urodynamic findings in predicting upper urinary tract damage in neuro-urological patients: A systematic review

AIM

The main goals of neurogenic lower urinary tract dysfunction (NLUTD) management are preventing upper urinary tract damage (UUTD), improving continence, and quality of life. Here, we aimed to systematically assess all available evidence on urodynamics predicting UUTD in patients with NLUTD.

METHODS

A systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement was performed in March 2017. Only neuro-urological patients assessed by urodynamics were included. Any outcome of upper urinary tract function were evaluated.

RESULTS

Forty-nine studies (1 randomized controlled trial, 9 prospective, and 39 retrospective case series) reported urodynamic data on 4930 neuro-urological patients. Of those, 2828 (98%) were spina bifida (SB) children. The total number of adults was 2044, mainly having spinal cord injury (SCI) (60%). A low bladder compliance was found in 568 (46.3%) and 341 (29.3%) of the paediatric and adult population, respectively. Hydronephrosis (HDN) was detected in 557 children (27.8%) in 19/28 studies and 178 adults (14.6%), mainly SCI, in 14/21 studies. Nine out of 30 multiple sclerosis (MS) patients affected by HDN (16.8%) showed low compliance in 4/14 studies.

CONCLUSIONS

Patients with SB and SCI have a higher risk of developing UUTD (mainly reported as HDN) compared to those with MS. Reduced compliance and high DLPP were major risk factors for UUTD. Although our findings clarify the mandatory role of urodynamics in the management of NLUTD, standardization and better implementation of assessments in daily practice may further improve outcomes of neuro-urological patients based on objective measurements, that is, urodynamics.

Sexuality and seeking medical help for erectile dysfunction in young adults with spina bifida

OBJECTIVES

The objectives of this study were to evaluate the correlation between the sexual function of spina bifida (SB) patients and Sharrard classification, touch sensation on the penis, to examine if SB patients who are sexually active have erectile dysfunction (ED) on the International Index of Erectile Function-5 (IIEF5), and to clarify if they seek medical treatment for ED.

METHODS

Thirty-six male SB patients aged over 18 years were enrolled. A questionnaire was sent to all patients that included the following items: touch sensation on the penis, psychogenic erection, rigidity at erection, ejaculation, orgasm and experience in sexual intercourse. In addition, patients who had experience in sexual intercourse were asked about ED through the use of the IIEF5 and whether or not they sought medical help for their ED.

RESULTS

Twenty-six patients responded. The positive rates of psychogenic erection, rigidity at erection, ejaculation and orgasm were 85%, 54%, 88% and 65% respectively. Psychogenic erection and ejaculation correlated with Sharrard classification. Rigidity at erection and orgasm correlated with touch sensation on the penis. Eleven patients had experience in sexual intercourse and six of them were diagnosed as having ED on the IIEF5. There were no factors correlating with ED. None of the patients sought medical advice and none was treated for ED.

CONCLUSIONS

Sexual function of SB patients could be predicted by Sharrard classification and touch sensation on the penis to some degree. However, ED did not correlate with sexual function. Therefore, we should not evaluate the neurological loss but instead provide adequate information.
