[Use of tadalafil in the rehabilitation of patients with a history of posterior urethral injury in the context of pelvic fracture]

Effects of continuous use of Tadalafil on male sexual function after posterior urethroplasty: A clinical trial

INTRODUCTION

Posterior urethral injuries in men commonly occur following pelvic and perineal trauma. Erectile dysfunction (ED), whether brought on by the severity of the initial trauma or the surgery itself, is one of the complications in these patients.

MATERIALS AND METHODS

In this study, we divided candidates of posterior urethroplasty due to traumatic urethral injury into intervention and placebo groups; the former received continuous treatment with tadalafil (10 mg daily), and the latter received a placebo. Other services were provided equally to both groups. Before and after the intervention, both groups completed the International Index of Erectile Function version 5 (IIEF-5) questionnaire, and the findings were analyzed.

RESULTS

Forty patients were studied in groups of 20 with a mean age of 43.87 ± 15.70 years. The patient's most common cause of urethral injury was a pelvic fracture. Before the intervention, the mean scores of IIEF for patients in the intervention group and placebo group were 14.85 ± 7.39 and 14.77 ± 6.48, respectively with no statistical significance (p = 0.962) and patients of the groups were similar in terms of the severity of ED. The mean IIEF score in the intervention group was 20.12 ± 4.94 and in the placebo group, it was 18.05 ± 4.88 at the three-month follow-up, with no statistically significant difference (p = 0.063). In both the intervention and placebo groups, the IIEF score was significantly increased by 5.27 ± 4.04 (p < 0.001) and 3.27 ± 2.97 (p < 0.001), respectively. The rate of IIEF increase in the intervention group was higher than in the placebo group during the follow-up at 3-month follow-up with statistical significance. (p = 0.022).

CONCLUSION

The findings of this study suggest that tadalafil, in a 3-month treatment course, may improve erectile function in individuals with mild-to-moderate ED, significantly more than placebo. However, more studies, specifically with longer duration of follow-up and larger populations, are necessary for generalizing the current findings.

Rehabilitative management of pelvic fractures: a literature-based update

A comprehensive rehabilitation program is required after Pelvic Fracture (PF). In a PF rehabilitation setting an effective treatment and a proper management of complications is supplied by an appropriate and reliable clinical assessment. In this literature-based update, we search on MEDLINE, EMBASE, and the Cochrane Database of Systematic reviews to find articles, scientific society guidelines and practioners experiences defining the rehabilitative management of clinically PF outcomes. Based on literature evidences and expert opinions, a set of key topics was collated to generate advices and recommendations to put into daily practice. Even if there are no high-quality evidence for rehabilitative interventions after PF in terms of duration and modality of therapy, rehabilitation setting, care pathways, and long-term functional outcomes, it is strongly recommended an early multidisciplinary intervention to improve recovery from PF.

Erectile dysfunction and penile rehabilitation after pelvic fracture: a systematic review and meta-analysis

OBJECTIVE

To investigate the rate of erectile dysfunction (ED) after pelvic ring fracture (PRF).

DESIGN

Systematic review and meta-analysis.

METHODS

A systematic literature search of the Cochrane, EMBASE, MEDLINE, Scopus and Web of Science Library databases was conducted in January 2020. Included were original studies performed on humans assessing ED after PRF according to the 5-item International Index of Erectile Function (IIEF-5) questionnaire and fracture classification following Young and Burgess, Tile or Arbeitsgemeinschaft für Osteosynthesefragen/Orthopedic Trauma Association. Furthermore, interventional cohort studies assessing the effect of penile rehabilitation therapy with phosphodiesterase-5-inhibitors (PDE-5-I) on IIEF-5 scores compared before and after treatment were included. Results were presented as forest plots of proportions of patients with ED after PRF or mean changes on IIEF-5 questionnaires before and after penile rehabilitation. Studies not included in the quantitative analysis were narratively summarised. Risk of bias assessment was conducted using the revised tool for the Quality Assessment on Diagnostic Accuracy Studies.

RESULTS

The systematic literature search retrieved 617 articles. Seven articles were included in the qualitative analysis and the meta-analysis. Pooled proportions revealed 37% of patients with ED after suffering any form of PRF (result on probability scale pr=0.37, 95% CI: 0.26 to 0.50). Patients after 3 months of penile rehabilitation therapy reported a higher IIEF-5 score than before (change score=6.5 points, 95% CI: 2.54 to 10.46, p value=0.0013).

CONCLUSION

Despite some heterogeneity and limited high-quality research, this study concludes that patients suffering from any type of PRF have an increased risk of developing ED. Oral intake of PDE-5-I for the purpose of penile rehabilitation therapy increases IIEF-5 scores and may relevantly influence quality-of-life in these patients.
