PURPOSE: To evaluate expansion of image-guided interventional cryoablation techniques usually employed for pain management to address the feasibility, safety, and efficacy of treatment for a urologic condition with otherwise limited treatment options, premature ejaculation (PE). MATERIALS AND METHODS: Prospective institutional review board approval was obtained, and 24 subjects with PE were enrolled. All patients underwent unilateral percutaneous computed tomography-guided cryoablation of the dorsal penile nerve (DPN). Postprocedural intravaginal ejaculatory latency times (IELTs) and PE Profile (PEP) results served as outcome variables. In addition, subjects were asked whether they would have the procedure done again based on their experience at the 180- and 360-day marks. RESULTS: The technical success rate was 100%. Baseline average IELT was 54.7 seconds±7.8 (n = 24), which increased to a maximum of 256 seconds±104 (n = 11; P = .241) by day 7 and decreased to 182.5 seconds±87.8 (n = 6; P = .0342) by day 90. The mean IELT remained at 182.5 seconds±27.6 at day 180 (n = 23; P<.0001) and decreased to 140.9 seconds±83.6 by 1 year (n = 22; P<.001). PEP scores improved overall, IELTs significantly improved at 180 and 360 days, and 83% of subjects reported that they would undergo the procedure again if given the same opportunity. There were no procedure-related complications. CONCLUSIONS: CT-guided percutaneous unilateral cryoablation of the DPN is a feasible, safe, single-day outpatient procedure for the treatment of symptomatic PE.

Little is known regarding the outcomes of endovascular and surgical treatment of penetrating ulcers in the abdominal aorta. The potential benefit of conservative management of asymptomatic disease is also debatable. A systematic review of the literature was undertaken to investigate these issues.

To evaluate the feasibility and effects of transcatheter arterial embolization with imipenem/cilastatin sodium (CS) to treat tendinopathy and enthesopathy that are refractory to traditional nonsurgical management.

Concepts: Radiology, Embolization


To compare the intensity of muscle contractions in irreversible electroporation (IRE) treatments when traditional IRE and high-frequency IRE (H-FIRE) waveforms are used in combination with a single applicator and distal grounding pad (A+GP) configuration.


To compare: (i) rate of arteriovenous fistula (AVF) interventions in both incident and prevalent end-stage kidney disease patients; (ii) their associated costs; and (iii) intervention-free survival between patients with surgical hemodialysis arteriovenous fistula (SAVF) versus those with an endovascularly created fistula (endoAVF).
