MRI is a useful tool to predict UI after RP. The MUL and PV are well-identified structures that are involved in UI. Our study shows that UWT also influences UI.

Urinary incontinence after radical prostatectomy has different prevalence depending on the definition. Age, prior transurethral resection of the prostate (TURP), membranous urethral length (MUL) and urethral wall thickness (UWT) were risk factors.

Urinary incontinence, understood as any involuntary loss of urine, constitutes an important medical and social problem. It can be classified as stress urinary incontinence, urgent urinary incontinence or mixed urinary incontinence. The proportions of these three types of urinary incontinence are difficult to establish and vary notably between sources, but they might be about 40, 33 and 20% respectively. Its diagnosis requires a correct clinical history and physical exploration, together with some complementary explorations. The first therapeutic step consists of hygienic-dietary measures and behaviour modification techniques. Pharmacological treatment is specific for each type of urinary incontinence, using anticholinergics and inhibitors of serotonin reuptake. Finally, different surgical techniques have a role in cases where conservative treatments fail or when dealing with severe urinary incontinence.

Recipient characteristics are the primary determinants of wound, urological and minor (Clavien grades I, II and III) complications; however, graft or donor characteristics are the primary risk factors for vascular, overall and major (Clavien grade IV) surgical complications.

Transplantation of kidneys from expanded criteria donors is associated with a significant higher risk of medical and surgical complications than kidneys from non-expanded criteria donors.
