Synopsis
This article reviews recent publications evaluating the current epidemiology of urologic trauma. It begins by providing a brief explanation of databases that have been recently used to study this patient population, then proceeds to discuss each genitourinary organ individually, discussing the most relevant and up to date information published for each one. The conclusion of the article briefly discusses possible future research and development areas pertaining to the topic.
Purpose
Although long-term outcomes after initial placement of artificial urinary sphincters are established, limited data exist comparing sphincter survival in patients with compromised urethras (prior radiation, artificial urinary sphincter placement or urethroplasty). We evaluated artificial urinary sphincter failure in patients with compromised and noncompromised urethras.
Materials and Methods
We performed a retrospective analysis of 86 sphincters placed at a single institution between December 1997 and September 2012. We assessed patient demographic, comorbid disease and surgical characteristics. All nonfunctioning, eroded or infected devices were considered failures.
Results
Of the 86 patients reviewed 67 (78%) had compromised urethras and had higher failure rates than the noncompromised group (34% vs 21%, p=0.02). Compared to the noncompromised group, cases of prior radiation therapy (HR 4.78; 95% CI 1.27, 18.04), urethroplasty (HR 8.61; 95% CI 1.27, 58.51) and previous artificial urinary sphincter placement (HR 8.14; 95% CI 1.71, 38.82) had a significantly increased risk of failure. The risk of artificial urinary sphincter failure increased with more prior procedures. An increased risk of failure was observed after 3.5 cm cuff placement (HR 8.62; 95% CI 2.82, 26.36) but not transcorporal placement (HR 1.21; 95% CI 0.49, 2.99).
Conclusions
Artificial urinary sphincter placement in patients with compromised urethras from prior artificial urinary sphincter placement, radiation or urethroplasty had a statistically significant higher risk of failure than placement in patients with noncompromised urethras. Urethral mobilization and transection performed during posterior urethroplasty surgeries likely compromise urethral blood supply, predisposing patients to failure. Patients with severely compromised urethras from multiple prior procedures may have improved outcomes with transcorporal cuff placement rather than a 3.5 cm cuff.
Introduction
Self-insertion of penile foreign bodies is performed worldwide, largely due to a perception that it will enhance sexual performance and virility. There are relatively few cases reported in the United States.
Aim
We report three cases of Hispanic men incarcerated in separate southwest United States prisons who utilized a similar technique to insert foreign bodies fabricated out of dominos into the subcutaneous tissues of the penis.
Methods
Details of the three cases were retrospectively reviewed.
Main Outcome Measure
Resolution of the case.
Results
In each case, an incarcerated Hispanic male or fellow inmate filed a domino into a unique shape for placement under the penile skin. Utilizing the tip of a ballpoint pen or a sharpened shard of plastic to create a puncture wound, each man inserted the domino fragment into the subcutaneous tissue of the penis. All three men presented with infection requiring operative removal.
Conclusions
Incarcerated males put themselves at risk for injury and infection when attempting penile enhancement with improvised equipment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
