in order to prevent late complications. We aim to study the epide- miological, clinical and therapeutic characteristics of penile fracture as well as the patients’ sexuality outcome after treatment. METHODS: A retrospective study including 73 patients who underwent surgery for fracture of penis from january 2000 to december 2016. Detailed history and clincal findings, the delay time between fracture and management, as well as modalities of treat- ment were documented for each case. Postoperative erectile func- tion outcomes were assessed with the International Index of Erectile Function (IIEF-5), and the presence of postoperative penile curva- ture was noted. RESULTS: The median age of the patients was 32,6 years (interquartile range [IQR]: 19 - 50 years). 42 patients were married. The most common causes were forced manipulation of the erect penis while masturbating in 40 cases (55%) and blunt trauma during sexual inter- course in 28 cases (39%). The delay time between the fracture and consultation ranged from 1 hour to 5 days. 53 patients had presented less than 24 hours after the trauma. The symptoms reported were se- vere sharp pain, an expansive hematoma and penile deformity in all cases. In majority of cases (85%) the surgical approach was electively over the area of suspected fracture. The median length of tunica albuginea defect was 15 mm. Only one patient presented with Fournier gangrene immediately after surgery. Postoperative IIEF-5 scores were 21 and 23 at the first and third postoperative months, respectively. Meanwhile, 3 patients developed penile curvature, only one patient complained of sexual dysfunction and underwent a successful surgical treatment. CONCLUSIONS: The diagnosis of penile fracture includes detailed history and clinical examination. No paraclinical investigations are necessary. A normal sexuality is only insured by an early man- agement in order to avoid late complications.

However, this technique could cause postoperative erectile dysfunction. Treatment using nerve-regener- ation conduit (NRC) has been shown to be equally or more effective than the nerve autograft and nerve suture for patients with somatic nerve injuries. We investigated efficacy of NRC interposition on return of erectile function after wide excision during radical prostatectomy. METHODS: After institutional review board approval, a total of 78 patients (42 unilateral, 36 bilateral) underwent unilateral or bilateral wide excision during robot-assisted radical prostatectomy between December 2013 and September 2016. They were classi fied into 2 groups, that is unilateral nerve preservation with contralateral NRC (polyglycolic acid collagen tube; NerbridgeTM) interposition and bilateral wide excision with bilateral NRC interposition. Post- operative data of these patients were compared with the data ob- tained from 136 patients who underwent wide excision during RARP between October 2010 to November 2013. Potency was estimated by the SHIM score and erection hardness score (EHS). The data from the patients with preoperative SHIM score > 17 were used for the analyses. RESULTS: No complication related to the interposition of the NRC was observed. Recovery rates of the SHIM score to the baseline at 12 months postoperatively for unilateral and bilateral groups were 15.8% and 0%, respectively. The recovery of EHS scores to the baseline were not observed at 12 months post- operatively in both groups. The recovery rate of EHS score with NRC interposition group was not significantly higher than the rate without NRC interposition group for both of the unilateral and bilat- eral groups. CONCLUSIONS: NRC interposition did not improve post- operative erectile function in patients who received wide excision during RARP. Scaffold for peripheral autonomic nerve regeneration seemed not to work because mesh-like cavernous nerves could not be replaced by a linear nerve.

Moreover, in many areas, acute ischemic priapism is managed by Emergency Medicine providers. To date, the practice patterns and attitudes of urologists regarding the management of this entity are poorly characterized. METHODS: From July to September 2017, urologists in both academic and community-based practices were asked to anonymously complete an online survey detailing their management practices for acute ischemic priapism and attitudes toward its management by trainees and non-urology providers. Survey participants included urol- ogy residents, fellows, and practicing urologists. Participants were contacted through the Society for the Study of Male Reproduction (SSMR), state urological societies, and direct solicitation. Responses from pediatric urologists were excluded. RESULTS: 58 individuals responded to the survey and included 44 practicing urologists, 5 fellows, and 9 urology residents. Every American Urological Association (AUA) Section was repre- sented, and 39.7% of respondents practiced in a non-academic setting. 50% recommend oral agents (terbutaline, pseudoephedrine, Vol. 199, No. 4S, Supplement, Monday, May 21, 2018 THE JOURNAL OF UROLOGY â e1125
