RESULTS: After a median follow-up of 25.2 mo., 9.7% (29/300)of men exhibited stress incontinence (SUI). Fifteen (45/300) percent ofall patients had type II DM and 28% (83/300) were obese or greater.The 3 variables independently predictive of SUI in multivariate analysiswere age (mean: 60.3 in incontinent men vs. 57.4 yrs, p<0.04) (Oddsratio (OR):3.25, 95% Confidence Intervals (CI): 1.45 to 7.31), BMI (28.9vs. 27.5, p<0.05) (OR:2.09, 95% CI:1.02 to 4.73), and a history of DM(31% of men with SUI had DM vs. 12.3%, p<0.03) (OR:2.59, 95%CI:1.07 to 6.31). The risk of SUI increased linearly both with BMI:(BMI<30: 8.8%, BMI 30 to 34.5: 12.7%; BMI 35 to 39.9: 22.2%, and BMI¡Ý40: 33.3%) and age: (age � 50: 2.3%, age 51 to 60: 6.8%, age 61 to70: 16%, and age � 71: 25%) (p< 0.05). Diabetic patients exhibited a20% risk of SUI compared with 7.8% in non-diabetics (p<0.03), even inpatients with a BMI �25 (42.9% with DM vs. 4.1%, p< 0.003). No othervariables adversely affected SUI including PSA, prostate weight,operative time, blood loss, anastomotic leak, nerve sparing status,history of hypertension, or smoking.

CONCLUSIONS: Puerto Rican patients undergoing RP havetwice the incidence of DM than the US population and a high rate ofobesity. While Puerto Rican men who underwent RP who were notdiabetic, had a BMI< 30 and were younger than 61 years had a SUI rateof 3.4%, this increased to 14.5% with a BMI�30, 16.3% when older than60 years, and beyond 20% with DM even in the absence of obesity.These are important data to discuss with patients in order to establishrealistic expectations.

PD11-08PATIENT PERCEPTION OF PHYSICAL AND EMOTIONALDISTRESS RELATED TO URODYNAMICS TESTING AT THEUNIVERSITY OF MICHIGAN; A QUESTIONNAIRE-BASED STUDYAMONG MEN AND WOMEN WITH AND WITHOUT NEUROLOGICCONDITIONS

INTRODUCTION AND OBJECTIVES: Urodynamic testing is aninvasive procedure that can be associated with physical discomfort andemotional distress. The purpose of this study was to identify patients’perceptions of this test according to gender and neurologic status.

METHODS: This is a questionnaire-based pilot study completedby patients immediately after undergoing urodynamic testing. Partici-pants were asked questions pertaining to their perceptions of physicaland emotional distress related to the study, their urologic and generalhealth history, and their demographics. Results were stratified by genderand the presence of neurologic conditions.

RESULTS: A total of 108 patients completed the questionnaire.The majority of respondents (62.0%) felt that the exam was neitherphysically nor emotionally distressing, and 31.0% felt that the physicaldistress was worse than the emotional distress (Table). The worst partof the physical discomfort was the placement of the urethral catheter(36.8% in males, 35.1% in females). Pain associated with placement ofthe rectal catheter was low in both groups (7.9% in males and 3.9% infemales). Results stratified by the presence of neurologic conditionsfollowed a similar pattern; however, respondents with neurologicconditions reported no physical discomfort more often (40.7%compared to 29.7% in non-neurologic respondents). In terms ofemotional distress, most respondents reported no emotional distressassociated with the urodynamics study (51.5%), followed by anxiety(24.2%), embarrassment (16.2%), and not understanding what washappening (2.0%). Results were similar regardless of gender or thepresence of a neurologic condition.

CONCLUSIONS: Urodynamic studies are well tolerated by menand women both with and without neurologic conditions. Patientperception of physical discomfort tended to be worse than that ofemotional discomfort, with placement of the urethral catheter causingthe most physical distress.

Patient reported perceptions of physical and emotional distress stratified bygender and neurologic status. Results are presented as percentages.

INTRODUCTION AND OBJECTIVES: Aim of the present studywas to investigate external urethral sphincter (EUS) activity by quanti-tative electromyography (EMG) using a new approach and assesscorrelations with urinary symptoms and prostate-related magneticresonance imaging (MRI) parameters.

METHODS: 58 men submitted to transrectal ultrasound-guided(TRUS) prostate biopsy had a computer-assisted EMG [Motor UnitPotential (MUP) and Interference Pattern (IP) analysis] of EUS by usingtransperineal approach in lithotomy position. EMG needle positioningwas driven by oscilloscopic, acoustic and TRUS guidance. Clinical dataincluding body mass index (BMI), Charlson Comorbidity Index (CCI),ICS-male SF, IPSS, and I-QoL questionnaires were collected for eachpatient; prostate volume and membranous urethral length weremeasured in prostate cancer patients submitted to MRI-staging (n ¼17). Linear correlation test (Spearman) was used to investigate corre-lations between clinical variables and EUS-EMG parameters. On theother hand regression models tested the dependence of clinical pa-rameters on repressors IPfreq IPamp.

RESULTS: The preliminary analysis of 20 consecutive signalsfor each MUP and IP parameters from the right and left EUS-sideshowed in all patients no significant differences or trends and compa-rable results supporting the use of the mean value. Throughout thesample, the means for MUPs parameters were: duration 6.9�1 ms,amplitude 411.2�164.2 ìV, phases 3.6�0.7, turns 2.1�0.6. For IP:amplitude/turns 308.2�71.8 ìV, number of turns/s 232.5�154.1 Hz andamplitude/turn divided by turns/s 1.4�2.1. No significant correlation
