RESUMEN
PURPOSE: Nocturia (waking from sleep at night to void) is a common cause of sleep disruption associated with increased comorbidity and impaired quality of life. However, its impact on mortality remains unclear. We performed a systematic review and meta-analysis to evaluate the association of nocturia with mortality as a prognostic factor and a causal risk factor. MATERIALS AND METHODS: We searched PubMed®, Scopus®, CINAHL® (Cumulative Index of Nursing and Allied Health Literature) and major conference abstracts up to December 31, 2018. Random effects meta-analyses were done to address the adjusted RR of mortality in people with nocturia. Meta-regression was performed to explore potential determinants of heterogeneity, including the risk of bias. We applied the GRADE (Grades of Recommendation, Assessment, Development and Evaluation) framework to rate the quality of evidence for nocturia as a prognostic risk factor for mortality and separately as a cause of mortality. RESULTS: Of the 5,230 identified reports 11 observational studies proved eligible for inclusion. To assess nocturia 10 studies used symptom questionnaires and 1 used frequency-volume charts. Nocturia was defined as 2 or more episodes per night in 6 studies (55%) and as 3 or more episodes per night in 5 (45%). Pooled estimates demonstrated a RR of 1.27 (95% CI 1.16-1.40, I2=48%) with an absolute 1.6% and 4.0% 5-year mortality difference in individuals 60 and 75 years old, respectively. The pooled estimates of relative risk did not differ significantly across varying age, gender, followup, nocturia case definition, risk of bias or study region. We rated the quality of evidence for nocturia as a prognostic factor as moderate and as a cause of mortality as very low. CONCLUSIONS: Nocturia is probably associated with an approximately 1.3-fold increased risk of death.

PURPOSE: Although nocturia is associated with various comorbidities, its impact on falls and fractures remains unclear. We performed a systematic review and meta-analysis to evaluate the association between nocturia and falls and fractures as a prognostic and as a causal risk factor. MATERIALS AND METHODS: We searched PubMed®, Scopus®, CINAHL (Cumulative Index to Nursing and Allied Health Literature) and abstracts of major urological meetings up to December 31, 2018. We conducted random effects meta-analyses of adjusted relative risks of falls and fractures. We applied the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) approach to rate the quality of evidence for nocturia as a prognostic and causal factor of falls and fractures. RESULTS: Among 5,230 potential reports 9 observational longitudinal studies provided data on the association between nocturia and falls or fractures (1 for both, 4 for falls, 4 for fractures). Pooled estimates demonstrated a risk ratio of 1.20 (95% CI 1.05-1.37, I2=51.7%, annual risk difference 7.5% among the elderly) for association between nocturia and falls and 1.32 (95% CI 0.99-1.76, I2=57.5%, annual risk difference 1.2%) for association between nocturia and fractures. Subgroup analyses showed no significant effect modification by age, gender, followup time, nocturia case definition or risk of bias. We rated the quality of evidence for nocturia as a prognostic factor as moderate for falls and low for fractures, and as very low as a cause of falls/fractures. CONCLUSIONS: Nocturia is probably associated with an approximately 1.2-fold increased risk of falls and possibly an approximately 1.3-fold increased risk of fractures.

The management of clinical benign prostatic hyperplasia (BPH) remains a common problem in daily urologic practice. Recently, a new minimally invasive procedure for BPH, the Urolift System, has been introduced. This article reviews the current literature discussing the technique, efficacy, adverse events, limitations, and possible concerns. The existing data which includes a 3-month, sham-controlled multicenter trial with a subsequent 3-year follow-up indicates significant improvements in the outcome measures in particular urinary symptoms. The adverse event profile and reoperation rates are acceptable. A particular benefit includes the lack of negative effects on erectile or ejaculatory function. The procedure can be performed with minimal anesthesia, but is limited to lateral lobe enlargement as it is unsuitable for median lobe or central zone obstruction. Another potential drawback is the placement of permanent implants into the prostatic urethra. The adoption of this procedure will ultimately be determined by multiple factors including ease of use, patient satisfaction, durability, and reimbursement.

INTRODUCTION: To develop and validate a lower urinary tract symptom score (LUTSS) as a measure of lower urinary tract symptom (LUTS) severity and a treatment outcome tool in adults. MATERIALS AND METHODS: An expert panel was convened to develop the LUTSS questionnaire. Content validity was achieved by obtaining subject and expert feedback from two prospective drafts. Subjects were divided into three groups: normal, LUTS and overactive bladder (OAB). Questionnaire was administered on two separate occasions within 1-2 weeks. Test-retest reliability, internal consistency, discriminant validity, criterion validity and responsiveness to change were also assessed. RESULTS: The questionnaire contains 14 questions with answers scored on a 5-point Likert scale (0-4). It includes 9 storage, 4 voiding and 1 bother question. One hundred ninety-one patients completed it; 80 males and 111 females, mean age 65 years (range 22-91). Seventy-two had OAB, 91 LUTS without OAB and 28 were normal. Test-retest intraclass correlation was 0.96 and Cronbach's-â¡ was 0.77, indicating strong test-retest reliability and internal consistency, respectively. ANOVA and post-hoc bootstrap-generated adjustments showed significant differences between the three groups (p < 0.001), demonstrating discriminant validity. Responsiveness to change was exhibited by the significant decrease between preop and postop scores and a concurrent patient global impression of improvement (PGI-I) score indicative of symptomatic improvement. CONCLUSION: The 14-question LUTSS is a validated questionnaire that assesses a full range of LUTS in men and women. The ordinal nature of the data with its highly specific description of symptoms makes it ideally suited as a nuanced and comprehensive symptom score and patient reported outcome (PRO) tool.

PURPOSE: We analyzed the correlation between pad use, as determined by objective pad count, and the severity of urinary incontinence, as measured by pad weight. MATERIALS AND METHODS: We performed a retrospective study of consecutive incontinent patients who wore pads on a daily basis and were instructed to complete a 24-hour pad test. They were told to use the usual pads, change them as usual and place each in a separate plastic bag the day before the scheduled appointment. All pads were weighed and total urine loss was calculated by subtracting dry pad weight from wet pad weight, assuming that a 1 gm weight increase was equivalent to 1 ml of urine loss. The number of pads was correlated to pad weight using the Spearman rank correlation coefficient due to the nonparametric nature of the data. RESULTS: The 116 patients included 51 men 39 to 89 years old (mean age 66) and 65 women 27 to 95 years old (mean age 72). When comparing the number of pads used to the gm of urine lost, the Spearman ρ was 0.26 (p=0.005) in the total cohort, and 0.40 and 0.26 (each p<0.05) in males and females, respectively. CONCLUSIONS: There was little correlation between the number of pads used and the severity of urinary incontinence (r=0.26). These data suggest that pad count should not be used as an objective measure of incontinence severity. Instead, pad weight on a 24-hour pad test should be used.

PURPOSE: We report our experience with the diagnosis and treatment of refractory synthetic sling complications in women. MATERIALS AND METHODS: This is a retrospective study of consecutive women with failed treatments for mesh sling complications. Before and after surgery the patients completed validated questionnaires and voiding diaries, and underwent uroflow with post-void residuals, pad test, cystourethroscopy and videourodynamic studies. Treatment was individualized, and results were subdivided into the 2 groups of conditions and symptoms. Outcomes were assessed with the Patient Global Impression of Improvement with success classified as a score of 1, improvement as 2 to 3 and failure as 4 to 7. RESULTS: A total of 47 women 35 to 83 years old (mean 60) had undergone at least 1 prior operation (range 1 to 4) to correct sling complications. Original sling composition was type 1 mesh in 36 patients and types 2 and 3 in 11. Surgical procedures included sling incision, sling excision, urethrolysis, urethral reconstruction, ureteroneocystotomy, cystectomy and urinary diversion, and enterocystoplasty. Median followup was 2 years (range 0.25 to 12, mean 3). Overall a successful outcome was achieved in 34 of 47 patients (72%) after the first salvage surgery. Reasons for failure were multiple for each patient. Of the 13 patients with treatment failure 9 subsequently underwent 14 operations. Success/improvement was achieved in 5 women (56%) after continent urinary diversion (1), continent urinary diversion and cystectomy (1), partial cystectomy and augmentation cystoplasty (1), biological sling and sinus tract excision (1), and vaginal mesh excision (1). CONCLUSIONS: Success after the initial failure of mesh sling complications repair is possible but multiple surgeries may be required. Each symptom should be addressed separately.

PURPOSE: We describe the diagnosis and treatment of urethral strictures in women. MATERIALS AND METHODS: We retrospectively identified female urethral strictures from 1998 to 2010. Study inclusion criteria were 1) clinical diagnosis of stricture, 2) stricture seen on cystoscopy, 3) urethral obstruction on videourodynamics according to the Blaivas-Groutz nomogram and/or 4) urethral caliber less than 17Fr. Postoperative recurrence was defined by the preoperative criteria. RESULTS: We identified 17 women with a mean age of 62 years (range 32 to 91) with stricture. Stricture was idiopathic in 8 patients, iatrogenic in 6, traumatic in 2 and associated with a urethral diverticulum in 1. Videourodynamics could not be done in 3 women due to complete obliteration of the urethra. Ten of 14 patients satisfied videourodynamic criteria for obstruction and 4 had impaired detrusor contractility. Nine women underwent vaginal flap urethroplasty, including 5 who also had a pubovaginal sling and 1 who had a Martius flap. One patient received a buccal mucosal graft as primary treatment after initial dilation. There was no recurrence at a minimum 1-year followup but 2 strictures recurred 5½ and 6 years postoperatively, respectively. These 2 women received a buccal mucosal graft and were stricture free 12 to 15 months postoperatively. Of 17 patients initially treated with urethral dilation recurrence developed in 16, requiring repeat dilations until urethroplasty was performed. CONCLUSIONS: In select women vaginal flap urethroplasty and buccal mucosal graft have high success rates, including 100% at 1 year and 78% at 5 years. Urethral dilation has a 6% success rate. Long-term followup is mandatory. Treatment should be individualized.

PURPOSE: To validate the Spanish translation of the Overactive Bladder Symptom Score (OABSS) questionnaire. MATERIALS AND METHODS: The OABSS was translated into Spanish (OABSS-S) and back translated. The OABSS-S was self-administered to subjects, following internal IRB and ISPOR Good Practices guidelines. Spanish speaking patients >18 years of age were recruited from primary care clinics. Content validity was achieved by having the first 25 subjects complete the questionnaire in privacy; afterwards they were interviewed and the clarity of each question was discussed with the patient. All subjects recruited, including the first 25, were divided into two groups by the presence of OAB as determined by a previously validated intake question. Subjects completed the OABSS-S in privacy on two occasions within 10 days. Patients were excluded if their symptoms changed between the first and second administration of the questionnaire. Internal consistency was determined with Cronbach's alpha. Test-retest was determined by Spearman's rho. Discriminant validity was assessed between each group using one-way ANOVA and the Tukey post hoc test. RESULTS: One hundred and seventeen of 128 enrolled subjects completed this study (mean age 55; SD 18). Of 117, 74 (63%) were women 29 with OAB and 45 without OAB. There were 43 men (37%), 18 with OAB and 25 without OAB. A high level of consistency was observed among the seven items answered at visit 1 and 2, with a Cronbach's raw alpha statistic of 0.92. No differences in OABSS-S with age or gender were noted. However, subgroup analysis showed patients in the OAB group were significantly older and post-test analysis showed they had higher scores both for each individual question as well as overall symptom severity scores. Spearman's rank order correlation coefficients showed that there was significant difference between the seven items of the OABSS-S; a strong association (Spearman's rho) was also observed between the total seven-item score at visits 1 and 2 for the total score of all subjects r = 0.84, with OAB: r = 0.81, and without OAB: r = 0.83. Comparison of average total scores obtained for all patients at visits 1 and 2 was not significant (10.47 ± 6.53 vs. 11.02 ± 0.66). Discriminant validity testing revealed that there were significant differences in the responses between all diagnostic groups at visits 1 and 2: with OAB versus without OAB; total versus with OAB; total versus without OAB. CONCLUSION: The Spanish version of the OABSS is valid and reliable and will allow health care providers to easily and quickly assess a Spanish-speaking patient's symptoms.

Adult renal rhabdomyosarcoma (RMS) is a rare and aggressive entity with a paucity of data and reports in the literature. As a result, treatment guidelines for this malignancy are not well-established. Herein, we present the diagnosis, management and clinical course of a 39-year-old patient diagnosed with primary renal embryonal RMS (ERMS) following radical nephrectomy. We also review the existing literature on primary renal ERMS.

Prostate cancer is the most common cancer in men. Men are diagnosed at early stages of prostate cancer with the use of prostate specific antigen. Surgical removal of the prostate is the standard treatment in localized prostate cancer. Complications after surgical procedures are inevitable. Although robotic prostatectomy has resulted in decreased complications compared to open surgery, complications occur. After an uneventful robotic assisted laparoscopic prostatectomy in a 71-year-old gentleman, with history of chronic cough and continued low dose glucocorticoid use, the patient returned to hospital with complain of a tender abdominal mass in right lower quadrant. After performing a computed tomography of the contrast, a Spigelian type trocar hernia was noted. The patient underwent a laparoscopic diagnostic surgery followed by small bowel resection and abdominal wall defect repair. The patient was discharged home with no other complains.
RESUMEN
INTRODUCTION: Overactive bladder symptoms (OAB) affect 9-43% of women and are associated with underlying disorders, including pelvic organ prolapse (POP) and stress urinary incontinence (SUI). The aim of this study is to identify urogynecological conditions associated with OAB symptoms. METHODS: This prospective, institutional review board-approved study included women referred to a tertiary centre with lower urinary tract symptoms (LUTS). All women completed the self-administered OAB questionnaire (OABSS). Those with an OABSS ≥8, the cutoff, were considered to have OAB symptoms. Patients underwent a history and physical examination (including Baden-Walker prolapse grading and stress test), 24-hour voiding diary, pad test (for urinary incontinence), urinalysis, and uroflow with post-void residual volume. Patients were classified clinically into the following: idiopathic OAB, SUI, POP, bladder outlet obstruction (BOO) neurogenic bladder (NGB), recurrent urinary tract infection (UTI), and miscellaneous. RESULTS: In total, 148 women met the inclusion criteria with a mean age of 67 years. Only 27% had no comorbid conditions and were considered idiopathic OAB. Associated urogynecological conditions included SUI in 37%, POP in 26%, miscellaneous conditions in 18%, recurrent UTI in 11%, NGB in 9%, and BOO in 8%. Some patients met criteria for more than one category, thus the total is greater than 100%. CONCLUSIONS: In a tertiary care setting, a significant proportion of women with OAB symptoms have underlying conditions that may cause or contribute to their symptoms. Appropriate evaluation is desirable to enhance our understanding of the relationship of these conditions to the diagnosis, treatment, outcomes, and pathophysiology of OAB.
RESUMEN
Operative management of prostate cancer in a patient who has undergone previous open suprapubic simple prostatectomy poses a unique surgical challenge. Herein, we describe a case of intermediate risk prostate cancer in a man who had undergone simple prostatectomy ten years prior to presentation. The patient was found to have Gleason 7 prostate cancer on MRI fusion biopsy of the prostate for elevated PSA and underwent an uncomplicated robot assisted laparoscopic radical prostatectomy.
RESUMEN
CONTEXT: Stress urinary incontinence (SUI) and urgency urinary incontinence (UUI) are associated with physical and psychological morbidity, and large societal costs. The long-term effects of delivery modes on each kind of incontinence remain uncertain. OBJECTIVE: To investigate the long-term impact of delivery mode on SUI and UUI. EVIDENCE ACQUISITION: We searched Medline, Scopus, CINAHL, and relevant major conference abstracts up to October 31, 2014, including any observational study with adjusted analyses or any randomized trial addressing the association between delivery mode and SUI or UUI ≥1 yr after delivery. Two reviewers extracted data, including incidence/prevalence of SUI and UUI by delivery modes, and assessed risk of bias. EVIDENCE SYNTHESIS: Pooled estimates from 15 eligible studies demonstrated an increased risk of SUI after vaginal delivery versus cesarean section (adjusted odds ratio [aOR]: 1.85; 95% confidence interval [CI], 1.56-2.19; I(2)=57%; risk difference: 8.2%). Metaregression demonstrated a larger effect of vaginal delivery among younger women (p=0.005). Four studies suggested no difference in the risk of SUI between spontaneous vaginal and instrumental delivery (aOR: 1.11; 95% CI, 0.84-1.45; I(2)=50%). Eight studies suggested an elevated risk of UUI after vaginal delivery versus cesarean section (aOR: 1.30; 95% CI, 1.02-1.65; I(2)=37%; risk difference: 2.6%). CONCLUSIONS: Compared with cesarean section, vaginal delivery is associated with an almost twofold increase in the risk of long-term SUI, with an absolute increase of 8%, and an effect that is largest in younger women. There is also an increased risk of UUI, with an absolute increase of approximately 3%. PATIENT SUMMARY: In this systematic review we looked for the long-term effects of childbirth on urinary leakage. We found that vaginal delivery is associated with an almost twofold increase in the risk of developing leakage with exertion, compared with cesarean section, with a smaller effect on leakage in association with urgency.

CONTEXT: Although vital for decision-making about management, the natural history of nocturia remains uncertain. A systematic review would clarify the issue, but because natural history reviews are uncommon it would require methodological innovations. OBJECTIVE: To estimate the incidence and remission of nocturia, and refine methods for meta-analyses assessing natural history. EVIDENCE ACQUISITION: We conducted a comprehensive search of PubMed, Scopus, and Cumulative Index of Nursing and Allied Health Literature databases and abstracts of major urologic meetings as far as August 31, 2015. Random effects meta-analyses addressed incidence/remission rates of nocturia; meta-regression explored potential determinants of heterogeneity. Studies were categorized as either low or high risk of bias using a novel instrument specifically designed for longitudinal symptom studies aimed at the general population. EVIDENCE SYNTHESIS: Of 4165 potentially relevant reports, 16 proved eligible. Pooled estimates from 13 studies (114 964 person-years of follow-up) demonstrated that annual incidence was strongly associated with age: 0.4% (0-0.8%) for adults aged < 40 yr; 2.8% (1.9-3.7%) for adults aged 40-59 yr; and 11.5% (9.1-14.0%) for adults aged ≥ 60 yr. Of those with nocturia, each year 12.1% (9.5-14.7%) experienced remission. CONCLUSIONS: The available evidence suggests that nocturia onset is strongly associated with age, with much higher rates in those over 60 yr; remission occurs in approximately 12% each year. These estimates can aid with management decisions and counseling related to nocturia. PATIENT SUMMARY: We reviewed all previous studies of progression of night-time urination (nocturia). We found that in any given year 0.4% of adults aged < 40 yr, 3% of adults aged 40-59 yr, and 12% of adults aged ≥ 60 yr will develop nocturia, while overall 12% of those with nocturia will improve. These findings may be helpful in making decisions about coping with or treating nocturia.

BACKGROUND: Many clinical practice guidelines, while recommending mechanical thromboprophylaxis after surgery, have raised concerns that discomfort may result in nonadherence. We therefore addressed adherence to mechanical thromboprophylaxis after surgery. METHODS: We searched MEDLINE from January 1, 2000 to May 21, 2015 for English-language observational studies that assessed patient adherence to mechanical thromboprophylaxis after surgery. We conducted a meta-analysis to estimate average adherence rates. RESULTS: We identified 8 studies (7 for compression devices, 1 for stockings) with median follow up time of 3days. The pooled estimate of adherence for compression devices was 75% (median 78%, range 40%-89%). Studies with shorter follow-up (≤3days, n=4, pooled adherence 75%) and longer follow-up (>3days, n=3, pooled adherence 75%) reported similar adherence (p=0.99). The studies varied in definitions of adherence, frequency of assessment, length of follow-up and completeness of reporting. No study followed patients after discharge. CONCLUSIONS: Up to one fourth of patients are nonadherent to mechanical thromboprophylaxis while hospitalized. Clinicians considering the relative merits of mechanical versus pharmacologic prophylaxis should address the issue of adherence. Strategies to improve adherence merit investigation.

OBJECTIVE: Nocturia may be characterized by indices derived from the frequency-volume chart (FVC). The objective of this study was to determine how these parameters relate to the severity of nocturia in men with and without lower urinary tract symptoms (LUTS). MATERIALS AND METHODS: A retrospective analysis of FVCs was performed in two cohorts of men: those presenting with LUTS in a New York ambulatory urology clinic and those from the longitudinal population-based Krimpen study. Nocturnal urine volume (NUV), nocturia index (Ni), nocturnal polyuria index (NPi), nocturnal maximal voided volume (nMVV) and sleep duration were derived from FVCs. Comparisons were made using Spearman's rank correlation coefficient between actual number of nightly voids (ANV) and the other diary parameters. RESULTS: Eighty-eight consecutive men who presented with LUTS completed a 24â h FVC [median age 70 years, interquartile range (IQR) 64.5-74.5, median ANV 2, IQR 1.5-4]. Nocturnal voiding frequency and volume were analyzed in 1082 community-dwelling men (median age 61 years, IQR 56.1-66.4, range 49.4-78.2; median ANV 1.5, IQR 1.0-2.0, range 0-4.5). Both cohorts demonstrated strong correlations between nocturia severity (represented as ANV) and Ni (0.797, 0.658 for cohorts 1 and 2, respectively). There were moderate correlations between nocturia severity and NPi (0.545, 0.394), NUV (0.463, 0.432) and sleep duration (0.306, 0.272). The nMVV correlated poorly with nocturia severity (0.159, 0.146). CONCLUSIONS: Treatment of nocturia should aim to match nocturnal urine production with bladder capacity. Given the lack of known effective pharmacotherapy for low bladder volume, the first attempt nocturia treatment could focus on volume reduction.

OBJECTIVE: The aim of this study was to explore the relationship between voided volume (VV) and urge to void among patients with lower urinary tract symptoms. MATERIAL AND METHODS: Consecutive adult patients (aged 23-90 years) were enrolled, and completed a 24 h bladder diary and the Urgency Perception Scale (UPS). Patients were categorized as urgency or non-urgency based on the Overactive Bladder Symptom Score. The relationship between UPS and VV (based on the bladder diary) was analyzed by Spearman's rho and proportional odds model. RESULTS: In total, 1265 micturitions were evaluated in 117 individuals (41 men, 76 women; 56 individuals in the urgency and 61 in the non-urgency group). The mean (± SD) VV and UPS were 192 ± 127 ml and 2.4 ± 1.2 ml in the urgency group and 173 ± 124 ml and 1.7 ± 1.1 ml in the non-urgency group, respectively. Spearman's rho (between UPS and VV) was 0.21 [95% confidence interval (CI) 0.13-029, p < 0.001] for the urgency group, 0.32 (95% CI 0.25-0.39, p < 0.001) for the non-urgency group, and 0.28 (95% CI 0.23-0.33, p < 0.001) for the total cohort. Urgency patients had higher UPS [odds ratio (OR) 3.1, 95% CI 2.5-3.8]. Overall, each additional 50 ml VV increased the odds of having a higher UPS with OR 1.2 (95% CI 1.2-1.3). The relationship between VV and UPS score was similar in both groups (p = 0.548 for interaction). CONCLUSION: Although urgency patients void with a higher UPS score, among both urgency and non-urgency patients there is only a weak correlation between VV and the urge to void. This suggests that there are factors other than VV that cause the urge to void.

OBJECTIVE: To report surgical outcomes in patients with impaired detrusor contractility (IDC) treated with reduction cystoplasty (RC). METHODS: This was a retrospective study of consecutive patients with IDC who underwent RC. IDC was defined as a bladder contractility index of <100 and/or a detrusor contraction of insufficient duration resulting in a postvoid residual volume (PVR) >600 mL. Bladder outlet obstruction was defined by a bladder outlet obstruction index (BOOI) >40. All patients had preoperative International Prostate Symptom Score, maximum uroflow (Qmax), PVR, bladder diary, videourodynamics, and cystoscopy. Patients with prostatic obstruction underwent synchronous open prostatectomy. Postoperative Qmax, PVR, need for clean intermittent catheterization (CIC), and Patient Global Impression of Improvement (PGII) score were obtained. Follow-up was at 3 months, 1 year, and yearly thereafter. RESULTS: Eight men met inclusion criteria (mean age, 60; range, 43-75 years). Preoperatively, 3 of 8 patients (37.5%) had moderate-sized bladder diverticula, 4 of 8 (50%) had a bladder contractility index <100, and 6 of 8 (75%) had a BOOI <40. Two patients (25%) fulfilled criteria for bladder outlet obstruction (BOOI, 67 and 72). Three (37.5%) underwent synchronous bladder diverticulectomy, and 3 (37.5%) underwent suprapubic prostatectomy. All patients were available for follow-up at 1 year. Seven of 8 (88%) had a successful outcome (PGII ≤2). One patient was unchanged (PGII, 4) and still needed CIC. CONCLUSION: All but 1 patient who met specific criteria for RC had excellent outcomes after surgery based on the PGII, PVR, Qmax, and need for CIC. RC is a viable option for properly selected patients with IDC.
