Lengthening strategies for Peyronie's disease.

Loss of penile length is a common complaint of men with Peyronie's disease (PD), both before and after corrective intervention, which has a significant negative effect on patient quality of life. We sought to identify and describe the methods by which penile length can be preserved or increased. We conducted an extensive, systematic literature review, based on a search of the PUBMED database for articles published between 1990 and 2015.

Comparison of 3 upper tract anticarcinogenic agent delivery techniques in an ex vivo porcine model.

Objective: To evaluate the degree of urothelial exposure using 3 upper tract delivery techniques in an ex vivo porcine model, to determine the optimal modality to locally deliver topical anticarcinogenic agents in patients with upper tract urothelial carcinoma.

Materials And Methods: An indigo carmine solution was infused into en bloc porcine urinary tracts to test the 3 techniques: antegrade infusion via nephrostomy tube, reflux via indwelling double-pigtail stent, and retrograde administration via a 5F open-ended ureteral catheter. Nine renal units (3 per delivery method) were used.
