Male Urinary Incontinence: Prevalence, Risk Factors, and Preventive Interventions

Systematic Review

Tatyana A ShamliyanJean F WymanRyan PingTimothy J WiltRobert L Kane

Urinary incontinence (UI) in community-dwelling men affects quality of lifeand increases the risk of institutionalization. Observational studies and randomized,controlled trials published in English from 1990 to November 2007on the epidemiology and prevention of UI were identified in several databasesto abstract rates and adjusted odds ratios (OR) of incontinence, calculateabsolute risk difference (ARD) after clinical interventions, and synthesizeevidence with random-effects models. Of 1083 articles identified, 126 wereeligible for analysis. Pooled prevalence of UI increased with age to 21% to32% in elderly men. Poor general health, comorbidities, severe physicallimitations, cognitive impairment, stroke (pooled OR 1.54; 95% confidenceinterval [CI], 1.14-2.1), urinary tract infections (pooled OR 3.49; 95%CI, 2.33-5.23), prostate diseases, and diabetes (pooled OR 1.36; 95% CI,1.14-1.61) were associated with UI. Treatment with tolterodine alone (ARD0.17; 95% CI, 0.02-0.32) or combined with tamsulosin (ARD 0.17; 95% CI,0.08-0.25) resulted in greater self-reported benefit compared with placebo.Radical prostatectomy or radiotherapy for prostate cancer compared withwatchful waiting increased UI. Short-term prevention of UI with pelvic floormuscle rehabilitation after prostatectomy was not consistently seen acrossrandomized, controlled trials. The prevalence of incontinence increased with ageand functional dependency. Stroke, diabetes, poor general health, radiation, andsurgery for prostate cancer were associated with UI in community-dwellingmen. Men reported overall benefit from drug treatments. Limited evidence ofpreventive effects of pelvic floor rehabilitation requires future investigation.[Rev Urol. 2009;11(3):145-165 doi:10.3909/riu0416]© 2009 MedReviews, LLC

Calyceal Diverticula: A Comprehensive Review

Disease State Review

Zeph OkekeNikhil WaingankarSamih HayekArthur D Smith

Calyceal diverticula are rare outpouchings of the upper collecting system that likely have a congenital origin. Stones can be found in up to 50% of calyceal diverticula, although, over the combined reported series, 96% of patients presented with stones. Diagnosis is best made by intravenous urography or computed tomography urogram. Shock wave lithotripsy (SWL) is an option for first-line therapy in patients with stone-bearing diverticula that have radiologically patent necks in mid- to upper-pole diverticula and small stone burdens. Stone-free rates are the lowest with SWL, although patients report being asymptomatic following therapy in up to 75% of cases with extended follow-up. Ureteroscopy (URS) is best suited for management of anteriorly located mid- to upper-pole diverticular stones. Drawbacks to URS include difficulty in identifying the ostium and low rate of obliteration. Percutaneous management is best used in posteriorly located mid- to lower-pole stones, and offers the ability to directly ablate the diverticulum. Percutaneous nephrolithotomy remains effective in the management of upper-pole diverticula, but carries the risk of pulmonary complications unless subcostal access strategies such as triangulation or renal displacement are used. Laparoscopic surgery provides definitive management, but should be reserved for cases with large stones in anteriorly located diverticula with thin overlying parenchyma, and cases that are refractory to other treatment. This article reviews the current theories on the pathogenesis of calyceal diverticula. The current classification is examined in addition to the current diagnostic methods. Here we summarize an extensive review of the literature on the outcomes of the different treatment approaches. [ Rev Urol. 2014;16(1):29-43 doi: 10.3909/riu0581] © 2014 MedReviews®, LLC
