Objective: To examine the rate of urethral trauma and pubic symphysis diastasis in saddle horn injury, which occurs when horseback riders are bucked into the air and land with their perineum striking the rigid saddle horn, compared to pelvic fracture from other mechanisms., Methods: A retrospective review was performed of male patients presenting to our level-1 trauma center with pelvic ring fractures between January 1, 2001 and December 30, 2016. Demographics, injury severity score, mechanism of injury (saddle horn vs other), pubic symphysis diastasis, and lower genitourinary (GU) injuries (bladder and urethra) were identified in the trauma registry. Chart review confirmed accuracy of lower GU trauma., Results: A total of 1195 males presented with pelvic ring fractures, average age 43 years (SD 19 years). Of these, 87 of 1195 (7%) presented with lower GU injuries. Saddle horn injuries had a higher rate of lower GU injuries, 12/60 (20%) versus 75 of 1135 (7%) [P = .001]. In those with lower GU injuries, 47 of 87 (54%) had urethral injury. The rate of urethral injury was significantly higher in the saddle horn cohort, 10 of 12 (83%) versus 37 of 75 (49%) [P = .03]. Furthermore, rate of pubic symphysis diastasis was higher amongst saddle horn injuries, 12 of 12 (100%) versus other mechanisms 39 of 75 (52%) [P = .001]., Conclusion: We found that urethral injury and pubic symphysis diastasis were higher in patients with saddle horn injury compared to other mechanisms of pelvic ring disruption. Clinicians should be aware of these associations when treating pelvic fracture following equestrian injuries., (Copyright © 2018. Published by Elsevier Inc.)

Female double urethra is a very rare anomaly, with less than 40 cases reported since 1970. Most reported cases of double urethra are in the sagittal plane and tend to be stenotic. We describe a 4-year-old girl with double urethra, which was not stenotic and was in the coronal plane. Double urethra should be excluded among other causes in any girl who is incontinent beyond the continence age., (Copyright © 2012 Elsevier Inc. All rights reserved.)

Introduction: Erectile dysfunction (ED) is a well-known consequence of pelvic fracture, particularly in cases involving urethral injury. There are several risk factors that may be related to ED. However, no systemic approach is used to assess erectile function secondary to urethral trauma., Aim: To investigate ED associated with urethral injury secondary to pelvic fracture and perineal trauma., Methods: Forty patients with traumatic urethral strictures secondary to blunt traumatic impact episode to the pelvis or perineum were included in our study. Pelvic fractures and urethral strictures were categorized according to injury types and radiological findings. All patients underwent nocturnal penile tumescence (NPT) monitoring, dynamic color-duplex Doppler ultrasonography (D-CDDU) before surgery. NPT monitoring was conducted again after surgery., Main Outcome Measures: The events of NPT and D-CDDU were recorded., Results: In all patients, 11 had organic ED demonstrated by NPT. Vascular pathology was identified in three of 11 patients (27%). The peak systolic velocity of cavernosal artery was lower in patients with pubic diastasis in comparison to those without diastasis (P < 0.05). Significant changes in penile length and circumference were noted in posterior urethral injury compared with anterior urethral injury during erection (P < 0.05). The erectile duration time has a similar statistical difference in two groups mentioned above. However, no significant difference could be observed in the end-to-end anatomosis procedure before and after surgery (P > 0.05)., Conclusions: The pelvic fracture type, especially pubic diastasis, is a risk factor for ED following urethral injury. Location of the stricture is also a risk factor for subsequent erectile dysfunction.
