Artificial urinary sphincter placement in compromised urethras and survival: a comparison of virgin, radiated and reoperative cases.
PurposeAlthough 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 methodsWe 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.ResultsOf 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).ConclusionsArtificial 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

Selective angioembolization for traumatic renal injuries: a survey on clinician practice.
PurposeA variety of clinical and imaging findings are used by clinicians to determine utility of renal angioembolization (AE) in managing renal trauma. Our purpose was to investigate specific criteria that clinicians who manage high-grade renal trauma (HGRT) utilize in decision-making for primary or delayed AE.MethodsA total of 413 urologists and interventional radiologists (IRs) who practice at level 1 or 2 trauma centers within the United States were provided an original survey via email on experience and opinions regarding the utility of AE for HGRT. We described overall practice patterns and assessed differences by clinician type, using the Fisher's exact test.ResultsA total of 79 (20 %) clinicians completed the survey. All clinicians had AE capability for HGRT management. A higher proportion of IRs reported using AE for grade I-II (33 vs. 3 %, p = 0.002), grade III (65 vs. 26 %, p = 0.001), and penetrating injuries (83 vs. 58 %, p = 0.02). A greater proportion of urologists reported using AE for grade V injuries (81 vs. 56 %, p = 0.03). Clinicians most commonly cited computed tomography evidence of active arterial bleeding (97 %), or arteriovenous fistula/pseudoaneurysm (94 %) as indications for primary AE, and 62 % identified concurrent visceral injury as factor that would necessitate surgical intervention.ConclusionIn a survey of clinicians, we report that IRs and urologists utilize AE differently when managing HGRT, as a higher proportion of IRs use AE to manage lower grade as well as penetrating injuries. Validation studies are needed to establish algorithms to identify patients with HGRT who would benefit from selective renal AE

No small slam: increasing incidents of genitourinary injury from toilets and toilet seats.
ObjectiveTo describe the epidemiology of genitourinary (GU) injury from toilets that present to USA Emergency rooms (ERs).Materials and methodsThe National Electronic Injury Surveillance System (NEISS) is a stratified probability sample of hospital ER visits for USA consumer product-related injuries. NEISS was used to estimate total toilet- and toilet seat-related GU injury for the years 2002-2010, as well as to describe demographics and injury characteristics. Analyses were performed using strata, primary sampling units and sample weights to accommodate the complex sample survey design. Data are reported as national estimates with 95% confidence intervals (CIs) provided.ResultsIn all, 13 175 (95% CI 10 185-16 165) GU injuries related to toilets presented to ERs during 2002-2010. The most common mechanism involved crush from accidental fall of toilet seat, described in 9011 (68.4%, 95% CI 6907-11 115) cases. Most crush injuries were isolated to the penis (98.1%). Of crush injuries, 81.7% occurred in children aged 2-3 years and 99.3% occurred in the home. Crush injuries increased over the period 2002-2010 (P = 0.017) by ≈100 per year, ending with an estimated 1707 (95% CI 1011-2402) by 2010. Most patients who sustained toilet- and toilet seat-related GU injuries were treated in the ER and then discharged.ConclusionWhile penile crush injury related to a toilet seat is an uncommon mechanism of urological injury in children, the number of incidents appears to be rising. These findings support educational efforts and interventions, such as exchange of heavy toilet seats with slow-close toilet seat technology
