Nocturnal polyuria in women: results from the EpiNP study.

INTRODUCTION AND HYPOTHESIS: Data from a large US population-based, cross-sectional, epidemiological study (the EpiNP Study) were used to assess the symptoms and bother experienced by women with nocturnal polyuria (NP). METHODS: Consenting participants recruited from an online panel completed the baseline EpiNP survey online (Lower Urinary Tract Symptoms Tool and urological comorbidities). All reporting ≥2 voids/night and a random sample of 100 respondents, each reporting 0 or 1 void/night were asked to complete a 3-day web-based bladder diary recording time, volume, and urgency rating of each void. NP was calculated by the proportion of urine production that occurred during nocturnal hours using a Nocturnal Polyuria Index (NPI33) threshold of >0.33 or nocturnal urine production of >90 ml/h (NUP90). The frequency of participants reporting LUTS and bother was determined by age and NP: idiopathic NP, NP associated with overactive bladder (NPOAB), NP associated with comorbidities (NPCom), and no NP (did not meet NP criteria). RESULTS: A total of 5,290 women completed the baseline survey. Mean age (range) was 54.9 (30-95) years; 1,841 (34.8%) reported ≥2 nocturnal voids. The prevalence of LUTS increased across the lifespan; however, bother associated with each LUTS decreased with increasing age. The percentage of women rating bother by nocturia episodes ≥2 "> somewhat" ranged from 40.3% to 68.3%, with bother ratings highest in the NPOAB and No NP groups. CONCLUSIONS: NP is prevalent in women with considerable bother and is often associated with other urinary symptoms. Multifactorial causes and potential treatments of NP should be considered, particularly at a later age.

Differences in the Prevalence of Nocturnal Polyuria in the U.S. by Definition: Results from the Epidemiology of Nocturnal Polyuria Study.

PURPOSE: Prevalence data on nocturnal polyuria (NP), nocturia caused by overproduction of urine during sleep, is primarily limited to men and varies by NP definition. This U.S.-representative epidemiological study of men and women ≥30 years old assessed the prevalence of NP. MATERIALS AND METHODS: Consenting participants completed the baseline EpiNP (Epidemiology of Nocturnal Polyuria) survey (eg Lower Urinary Tract Symptoms Tool, comorbidities). All reporting ≥2 voids/night and a target of 100 random respondents reporting 0 or 1 void/night were asked to complete 3-day bladder diaries. NP was defined as nocturnal polyuria index (NPI) >0.33 (NPI33) and nocturnal urine production >90 ml/hour (NUP90). Extrapolated prevalence was stratified by sex and subgroups: idiopathic (without underlying causes), associated with overactive bladder (NPOAB), bladder outlet obstruction (NPBOO; men) and comorbidities. Voided volumes and timing, including first uninterrupted sleep period, were assessed by subgroup. RESULTS: A total of 10,190 individuals completed the baseline survey; mean age (range) was 54.4 (30-95). A total of 3,938 individuals were invited to complete the diary; 1,763 (49.3%) completed 3-day bladder diaries. Urine production (maximum nighttime volume, total volume, nocturnal urine production, nocturia index) was higher in both men and women with idiopathic NP and comorbidities. The median number of nighttime voids was greatest for NPBOO in men and NPOAB in women. Bother associated with nighttime voiding differed by NP subgroup but was highest in NPBOO for men (NPI33: 69.6%; NUP90: 71.1%) and NPOAB for women (NPI33: 67.5%; NUP90: 66.0%). CONCLUSIONS: This population-based NP prevalence study including men and women characterizes NP subgroups and provides insights into nocturia treatment by emphasizing factors influencing urine production versus factors influencing bladder capacity.

The Prevalence of Nocturnal Polyuria in the United States: Results from the Epidemiology of Nocturnal Polyuria Study.

BACKGROUND: The prevalence of nocturnal polyuria (NP), which is passing large volumes of urine during the main sleep period, has been investigated primarily in middle-aged to older men. There is thus a gap in the NP evidence base for women and for younger individuals. OBJECTIVE: To estimate the prevalence of nocturia due to NP in the USA. DESIGN, SETTING, AND PARTICIPANTS: This large epidemiologic study used a US population-representative sample of men and women aged ≥30 yr to assess the prevalence of NP (NCT04125186). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Consenting participants completed an online survey (Lower Urinary Tract Symptoms Tool and comorbidities). All who reported two or more voids per night and 100 random respondents each reporting no or one void per night were asked to complete a 3-d bladder diary. Two NP definitions were used: nocturnal urine production >90 ml/h (NUP90) and Nocturnal Polyuria Index >0.33 (NPI33). Crude and population-adjusted prevalence results were calculated from completed diaries for the following subgroups by sex and age: idiopathic NP; NP with overactive bladder (NP-OAB) or bladder outlet obstruction (NP-BOO; men only); NP associated with other comorbidities; and no NP (did not meet the NPI33 or NUP90 definition). RESULTS AND LIMITATIONS: Among the 10,190 respondents who completed the survey, the mean age was 54.4 yr (range 30-95); 3,339 reported two or more nocturnal voids and 1,763 completed the 3-d diary (response rate 49.3%). The adjusted overall NP prevalence was 31.5% among men and 38.5% among women using the NPI33 definition, and 23.8% among men and 18.1% among women using NUP90. The adjusted idiopathic NP prevalence was lower among men (NPI33: 5.2%; NUP90: 1.4%) than among women (NPI33: 9.8%; NUP90: 4.0%). The prevalence of idiopathic NP decreased with age as NP associated with other possible causes increased with age in men (most common, BOO) and women (most common, OAB). CONCLUSIONS: This is the first population-based study of NP prevalence to include men, women, and young adults. NP is common; a multifactorial etiology should be considered, particularly as age increases. PATIENT SUMMARY: In this population-based US study, we examined the frequency of nighttime urination among men and women aged ≥30 y and older. We found that nighttime urination is common among men and women. Many conditions can lead to increased nighttime urination as people age.

Differences in treatment choices between prostate cancer patients using a decision aid and patients receiving care as usual: results from a randomized controlled trial.

OBJECTIVE: To determine whether or not decision aid (DA) use influences treatment decisions in patients with low and intermediate risk prostate cancer (PC). PATIENTS AND METHODS: In a cluster randomized controlled trial, patients were randomized to either DA use (DA group) or no DA use (control group). Between 2014 and 2016, newly diagnosed patients with low or intermediate risk PC were recruited in 18 hospitals in the Netherlands. DA users had access to a web-based DA that provided general PC information, PC-treatment information, and values clarification exercises to elicit personal preferences towards the treatment options. Control group patients received care as usual. Differences in treatment choice were analysed using multilevel logistic regressions. Differences in eligible treatment options between groups were compared using Pearson Chi-square tests. RESULTS: Informed consent was given by 382 patients (DA group N = 273, control group N = 109). Questionnaire response rate was 88% (N = 336). Active surveillance (AS) was an option for 38%, radical prostatectomy (RP) for 98%, external beam radiotherapy (EBRT) for 88%, and brachytherapy (BT) for 79% of patients. DA users received AS significantly more often than control group. Patients (29 vs 16%, p = 0.01), whereas the latter more often chose BT (29 vs 18%, p < 0.01). No differences were found between groups regarding RP and EBRT. DA users who were not eligible for AS, received surgery more often compared to the control group (53 vs 35%, p = 0.01). Patient and disease characteristics were evenly distributed between groups. CONCLUSION: DA-using PC patients chose the AS treatment option more often than non-DA-using patients did.

Additional surgical procedures and perioperative morbidity in post-chemotherapy retroperitoneal lymph node dissection for metastatic testicular cancer in two intermediate volume hospitals.

PURPOSE: To evaluate the perioperative morbidity of PC-RPLND in two intermediate volume centers and to identify predictors of high morbidity. METHODS: Retrospective analysis of 124 patients treated with open PC-RPLND at two tertiary referral centers between 2001 and 2018. Perioperative morbidity was determined by analyzing additional surgical procedures, intra-operative blood loss, and postoperative complications. RESULTS: An additional procedure was necessary for 33 patients (26.6%). The risk was higher in patients with IGCCCG intermediate/poor prognosis (OR 3.56; 95% CI 1.33-9.52) and residual tumor size > 5 cm (OR 3.53; 95% CI 1.39-8.93). Blood loss was higher in patients with IGCCCG intermediate/poor prognosis (ß = 0.177; p = 0.029), large residual tumor (ß = 0.570; p < 0.001), an additional intervention (ß = 0.342; p < 0.001) and teratoma on retroperitoneal histology (ß = - 0.19; p = 0.014). Thirty-one patients had a postoperative complication Clavien-Dindo Grade ≥ 2 (25.0%). Complication risk was highest in patients undergoing an additional intervention (OR 3.46; 95% CI 1.03-11.60; p = 0.044). CONCLUSIONS: The rate of additional interventions in our series is comparable to what has been reported in high-volume centers. IGCCCG intermediate/poor prognosis patients with high-volume disease and patients undergoing an additional surgical procedure can be classified as high-risk patients.

Clinical outcome of robot-assisted residual mass resection in metastatic nonseminomatous germ cell tumor.

PURPOSE: To evaluate the outcome of robot-assisted residual mass resection (RA-RMR) in nonseminomatous germ cell tumor (NSGCT) patients with residual tumor following chemotherapy. PATIENTS AND METHODS: Retrospective medical chart analysis of all patients with NSGCT undergoing RA-RMR at two tertiary referral centers between January 2007 and April 2019. Patients were considered for RA-RMR in case of a residual tumor between 10 and 50 mm at cross-sectional computed tomography (CT) imaging located ventrally or laterally from the aorta or vena cava, with normalized tumor markers following completion of chemotherapy, and no history of retroperitoneal surgery. RESULTS: A total of 45 patients were included in the analysis. The Royal Marsden stage before chemotherapy was IIA in 13 (28.9%), IIB in 16 (35.6%), IIC in 3 (6.7%) and IV in 13 patients (28.9%). The median residual tumor size was 1.9 cm (interquartile range [IQR] 1.4-2.8; range 1.0-5.0). Five procedures (11.1%) were converted to an open procedure due to a vascular injury (n = 2), technical difficulty (n = 2) or tumor debris leakage (n = 1). A postoperative adverse event occurred in two patients (4.4%). Histopathology showed teratoma, necrosis and viable cancer in 29 (64.4%), 14 (31.1%), and two patients (4.4%), respectively. After a median follow-up of 41 months (IQR 22-70), one patient (2.2%) relapsed in the retroperitoneum. The one- and 2-year recurrence-free survival rate was 98%. CONCLUSION: RA-RMR is an appropriate treatment option in selected patients, potentially providing excellent cure rates with minimal morbidity. Long-term outcome data are needed to further support this strategy and determine inclusion and exclusion criteria.

Psoas hitch procedure in 166 adult patients: The largest cohort study before the laparoscopic era.

Objectives: To present the short-term and long-term outcomes of the psoas hitch procedure in a large cohort with long-term follow-up. Patients and methods: A multicenter, retrospective cohort study was conducted. Patients were included if they had undergone an open psoas hitch procedure with ureteral reimplantation for different types of distal ureteral pathology between 1993 and 2017. Clinical failure was defined as radiologically-proven obstruction of the ureteroneocystostomy and/or post-operative complaints requiring additional surgery. Pre-operative demographic data and post-operative radiological imaging were collected. Complications were categorized as peri-operative, acute (<30 days), and long-term complications. Results: A total of 166 patients had undergone a psoas hitch procedure, with a median follow-up of 15 months (IQR 6-45). Indications for the procedure included intra-operative injury of the ureter during gynecological, urological or general surgery, transitional cell carcinoma of the distal ureter, fistulae, (radiation) fibrosis, and trauma. There was no significant difference in pre- and post-operative estimated glomerular filtration rate. Post-operative complications included urinary leakage, recurrent urinary tract symptoms, recurrent malignancy, and kidney failure. Postoperative imaging was available in 143 patients. Failure of the psoas hitch procedure was seen in 8% (11/143) of the patients. In 55% (6/11) of these patients, radiation fibrosis was the indication for the psoas hitch procedure. Conclusion: This study provides greater insight into the long-term complications of the open psoas hitch procedure in adults. The psoas hitch procedure can be considered a safe procedure for restoring the continuity of the ureter for different types of ureteral pathologies in adult patients. However, patients with a history of radiation therapy causing retroperitoneal fibrosis might be more prone to failure after the procedure.

Dose-Dependent Effect of Platinum-Based Chemotherapy on the Risk of Metachronous Contralateral Testicular Cancer.

PURPOSE: Patients with testicular germ cell tumor (TGCT) are at increased risk of developing a contralateral TGCT (CTGCT). Although some studies suggest that prior treatment with platinum-based chemotherapy affects CTGCT risk, a relationship between CTGCT risk and platinum dose has not previously been assessed. We analyzed the association between the number of platinum-based chemotherapy cycles and CTGCT risk. PATIENTS AND METHODS: The risk of developing a metachronous CTGCT was evaluated in a nationwide cohort of 4,755 patients diagnosed with primary TGCT in the Netherlands between 1989 and 2007. Standardized incidence ratios were computed to compare CTGCT incidence with expected TGCT on the basis of TGCT incidence in the general population. The cumulative incidence of CTGCT was estimated in the presence of death as competing risk. The effect of treatment with platinum-based chemotherapy on CTGCT risk was assessed using multivariable Cox proportional hazards regression models. RESULTS: CTGCT was diagnosed in 136 patients (standardized incidence ratio, 14.6; 95% CI, 12.2 to 17.2). The cumulative incidence increased up to 20 years after primary diagnosis, reaching 3.4% (95% CI, 2.8% to 4.0%) after 20 years of follow up. The risk of developing a CTGCT decreased with age (hazard ratio [HR], 0.93; 95% CI, 0.90 to 0.96), was lower after nonseminomatous germ cell tumor (HR, 0.58; 95% CI, 0.35 to 0.96) and decreased with every additional cycle of chemotherapy (HRper cycle, 0.74; 95% CI, 0.64 to 0.85). CONCLUSION: Approximately one in every 30 survivors of TGCT will develop a CTGCT, with CTGCT incidence increasing up to 20 years after a primary TGCT. Treatment with platinum-based chemotherapy shows a dose-dependent inverse association with CTGCT risk.

Systematic review and meta-analysis of the associations between body mass index, prostate cancer, advanced prostate cancer, and prostate-specific antigen.

PURPOSE: The relationship between body mass index (BMI) and prostate cancer remains unclear. However, there is an inverse association between BMI and prostate-specific antigen (PSA), used for prostate cancer screening. We conducted this review to estimate the associations between BMI and (1) prostate cancer, (2) advanced prostate cancer, and (3) PSA. METHODS: We searched PubMed and Embase for studies until 02 October 2017 and obtained individual participant data from four studies. In total, 78 studies were identified for the association between BMI and prostate cancer, 21 for BMI and advanced prostate cancer, and 35 for BMI and PSA. We performed random-effects meta-analysis of linear associations of log-PSA and prostate cancer with BMI and, to examine potential non-linearity, of associations between categories of BMI and each outcome. RESULTS: In the meta-analyses with continuous BMI, a 5 kg/m2 increase in BMI was associated with a percentage change in PSA of - 5.88% (95% CI - 6.87 to - 4.87). Using BMI categories, compared to normal weight men the PSA levels of overweight men were 3.43% lower (95% CI - 5.57 to - 1.23), and obese men were 12.9% lower (95% CI - 15.2 to - 10.7). Prostate cancer and advanced prostate cancer analyses showed little or no evidence associations. CONCLUSION: There is little or no evidence of an association between BMI and risk of prostate cancer or advanced prostate cancer, and strong evidence of an inverse and non-linear association between BMI and PSA. The association between BMI and prostate cancer is likely biased if missed diagnoses are not considered.

Is There Still a Need for Repeated Systematic Biopsies in Patients with Previous Negative Biopsies in the Era of Magnetic Resonance Imaging-targeted Biopsies of the Prostate?

BACKGROUND: The role of targeted prostate biopsies (TBs) in patients with cancer suspicious lesions on multiparametric magnetic resonance imaging (mpMRI) following negative systematic biopsies (SBs) is undebated. However, whether they should be combined with repeated SBs remains unclear. OBJECTIVE: To evaluate the value of repeated SBs in addition to TBs in patients with a prior negative SB and a persistent suspicion of prostate cancer (PCa). DESIGN, SETTING, AND PARTICIPANTS: A prospective study as part of a multicenter randomized controlled trial conducted between 2014 and 2017, including 665 men with a prior negative SB and a persistent suspicion of PCa (suspicious digital rectal examination and/or prostate-specific antigen >4.0ng/ml). INTERVENTION: All patients underwent 3T mpMRI according to Prostate Imaging Reporting and Data System (PI-RADS) v2. Patients with PI-RADS ≥3 were randomized 1:1:1 for three TB techniques: MRI-TRUS fusion TB (FUS-TB), cognitive registration fusion TB (COG-TB), or in-bore MRI TB. FUS-TB and COG-TB were combined with repeated SBs. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Clinically significant prostate cancer (csPCa) was defined as Gleason ≥3+4. Differences in detection rates of csPCa, clinically insignificant PCa (cisPCa), and overall PCa between TBs (FUS-TB and COG-TB) and repeated SBs were compared using McNemar's test. RESULTS AND LIMITATIONS: In the 152 patients who underwent both TB and SB, PCa was detected by TB in 47% and by SB in 32% (p<0.001, 95% confidence interval [CI]: 6.0-22%). TB detected significantly more csPCa than SB (32% vs 16%; p<0.001, 95% CI: 11-25%). Clinically significant PCa was missed by TB in 1.3% (2/152). Combining SB and TB resulted in detection rate differences of 6.0% for PCa, 5.0% for cisPCa, and 1.0% for csPCa compared with TB alone. CONCLUSIONS: In case of a persistent suspicion of PCa following a negative SB, TB detected significantly more csPCa cases than SB. The additional value of SB was limited, and only 1.3% of csPCa would have been missed when SB had been omitted. PATIENT SUMMARY: We evaluated the role of systematic biopsies and magnetic resonance imaging (MRI)-targeted biopsies for the diagnosis of prostate cancer in patients with prior negative systematic biopsies. MRI-targeted biopsies perform better in detecting prostate cancer in these patients. The value of repeated systematic biopsies is limited.

Patient-reported Outcomes Following Treatment of Localised Prostate Cancer and Their Association with Regret About Treatment Choices.

BACKGROUND: Well-documented reports of patients' experiences with different treatments are important for helping localised prostate cancer (LPC) patients choose among the available treatment options. OBJECTIVE: To document differences in patient-reported outcomes (PROs) following radical prostatectomy (RP), external beam radiotherapy (EBRT), brachytherapy (BT), and active surveillance (AS), and to evaluate how these PROs and other factors are associated with treatment decision regret. DESIGN, SETTING, AND PARTICIPANTS: A prospective, observational, multicentre study of men diagnosed with LPC (stage cT1-2) during 2014-2016. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Patients completed validated PRO measures (Quality of Life Questionnaire Core 30 [QLQ-C30], Quality of Life Questionnaire prostate cancer-specific module [QLQ-PR25], Decision Regret Scale, and the Memorial Anxiety Scale for Prostate Cancer) before treatment and at 3, 6, and 12mo after treatment. Mixed-effect models were used to describe different PRO patterns. RESULTS AND LIMITATIONS: The analytic cohort included 434 men (AS=32%; RP=45%; EBRT=12%; BT=10%). Follow-up response rates were above 90%. At 1-yr follow-up, (1) men who had received RP reported significantly (p<0.01) more urinary incontinence, sexual dysfunction, hormonal/masculinity-related symptoms, and less emotional distress; (2) those having received EBRT reported more sexual dysfunction, hormonal/masculinity-related symptoms, and physical distress; and (3) those having received BT reported more urinary obstruction and irritation symptoms, compared with patients under AS. Irrespective of the treatment modality, 23% of the patients reported clinically relevant treatment regret (99% confidence interval, 17-28%). Multivariate correlates of decision regret were hormonal/masculinity-related symptoms, educational level, and positive surgical margins. CONCLUSIONS: Post-treatment physical and psychosocial functioning was significantly associated with specific treatment modalities and pretreatment functioning. Regret was relatively frequently reported by patients who experienced unwanted physical, psychosocial, and oncological outcomes. Greater efforts should be made to understand whether carefully educating patients about the possible consequences and effectiveness of treatments may help limit the feeling of treatment regret. PATIENT SUMMARY: In men with localised prostate cancer, regret about the treatment choice was more common among those who experienced more treatment-related symptoms during the year after treatment.

Lymphovascular invasion and presence of embryonal carcinoma as risk factors for occult metastatic disease in clinical stage I nonseminomatous germ cell tumour: a systematic review and meta-analysis.

OBJECTIVE: To systematically review the literature on the prognostic value of lymphovascular invasion (LVI) and embryonal carcinoma (EC) for occult metastatic disease in clinical stage I nonseminomatous germ cell tumour (CS I NSGCT). MATERIALS AND METHODS: The PubMed, Embase (OVID) and SCOPUS databases were searched up to March 2019. Studies reporting on the association between LVI and/or EC and occult metastatic disease were considered for inclusion. The quality and risk of bias were evaluated by the Quality in Prognosis Studies tool. RESULTS: We screened 5287 abstracts and 207 full-text articles. We included 35 studies in the narrative synthesis and 24 studies in a meta-analysis. LVI showed the strongest effect. Pooled rates of occult metastasis were 47.5% and 16.9% for LVI-positive and LVI-negative patients, respectively (odds ratio [OR] 4.33, 95% confidence interval [CI] 3.55-5.30; P < 0.001). Pooled rates of occult metastasis were 33.2% for EC presence and 16.2% for EC absence (OR 2.49, 95% CI 1.64-3.77; P < 0.001). Pooled rates of occult metastasis were 40.0% for EC >50% and 20.0% for EC <50% (OR 2.62, 95% CI 1.93-3.56; P < 0.001). CONCLUSIONS: LVI is the strongest risk factor for relapse. The prognostic value of EC is high, but there is no common agreement on how to define this risk factor. Both EC presence and EC >50% have similar ORs for occult metastasis. This shows that the assessment of EC presence is sufficient for the classification of EC.

Complications and Adverse Events of Three Magnetic Resonance Imaging-based Target Biopsy Techniques in the Diagnosis of Prostate Cancer Among Men with Prior Negative Biopsies: Results from the FUTURE Trial, a Multicentre Randomised Controlled Trial.

BACKGROUND: Three techniques of magnetic resonance imaging (MRI)-based targeted biopsy (TB) of the prostate exist. There is no superiority regarding diagnostic efficacy of prostate cancer (PCa) detection. OBJECTIVE: To compare adverse events (AEs) among three TB techniques and to evaluate the effect on urinary and erectile function. DESIGN, SETTING, AND PARTICIPANTS: Post hoc analysis of a multicentre randomised controlled trial among men with negative systematic biopsy (SB) and suspicion of PCa. INTERVENTION: In 234 patients, 3-T multiparametric MRI demonstrated PIRADS≥ 3 lesions, and patients were randomised 1:1:1 for TB: transrectal in-bore MRI TB (MRI-TB), transperineal MRI-transrectal ultrasound (TRUS) fusion TB (FUS-TB), and transrectal cognitive TRUS TB (COG-TB). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: AEs (Clavien-Dindo) were compared using Pearson chi-square test. Univariate logistic regression tests were performed for the number of cores, biopsy approach, and usage of anticoagulants. The participants filled in baseline and 30-d postbiopsy International Prostate Symptom Score (IPSS) and International Index of Erectile Function (IIEF-5) questionnaires. The delta between measurements was compared using one-way analysis of variance. RESULTS AND LIMITATIONS: There were significant differences in minor AEs: 53% in MRI-TB, 71% in FUS-TB, and 85% in COG-TB (p < 0.001). The number of cores was associated with AEs (odds ratio [OR] 1.11 per extra biopsy [95% confidence interval {CI} 1.06-1.17, p < 0.001]). Anticoagulants were not associated with bleeding complications (OR 1.24 [95% CI 0.66-2.35, p = 0.5]). Transrectal approach (MRI-TB + COG-TB) increased the risk of any AE (OR 2.54 [95% CI 1.16-5.77, p < 0.05]) and nonsignificantly increased the risk of urinary tract infections (OR 3.69 [95% CI 0.46-168.4, p = 0.3]). Biopsy did not impact urinary (ΔIPSS 0.3, p = 0.1) and erectile function (ΔIIEF-5 -0.4, p = 0.5). The main limitation was that additional SB was performed in FUS-TB and COG-TB, and was omitted in MRI-TB, making comparison difficult. CONCLUSIONS: There was a significant difference in minor AEs among groups. An increase in the number of cores increased the overall risk of AEs. A low AE occurrence in MRI-TB was likely caused by the omission of SB. Prostate biopsy did not impact self-reported urinary and erectile functions. PATIENT SUMMARY: In this study, we compared the complication rates of three techniques of magnetic resonance imaging (MRI)-based targeted biopsy of the prostate. We found a significant difference in the occurrence of minor complication rates among three groups in favour of transrectal in-bore MRI targeted biopsy, likely caused by the omission of additional systematic biopsy in this group.

Coping styles in patients with hypospadias.

OBJECTIVE: The objective of this study is to investigate the coping styles used by patients with hypospadias. Long-term hypospadias studies generally show satisfying outcomes, but some report a lower quality of life (QoL) or poorer psychosocial adjustment, particularly in patients with proximal hypospadias. A lower QoL or psychosocial adjustment was found to be associated with passive coping styles in other pediatric patient populations. Hypothetically, patients with hypospadias also develop different coping styles due to medical experiences in childhood, leading to the lower QoL outcomes on the long term. However, coping styles of patients with hypospadias have never been analyzed. PATIENTS AND METHODS: Adult men with hypospadias repair in childhood were recruited (n = 55; aged 19.9 [IQR 19.2-22.1]). Coping styles were determined with the Utrecht Coping List (UCL) and results compared with a reference group of male students (n = 55, age 20-30 years, no medical history). Sub analysis of coping styles of the hypospadias groups was done based on three items: severity of hypospadias, time of last hypospadias surgery and occurrence of postoperative complications. RESULTS: Compared to the reference groups, patients with hypospadias had higher scores on Avoidance (P < 0.05), particularly patients who had ≥1 postoperative complication or proximal hypospadias. Patients with proximal hypospadias also had lower scores on Seeking Social Support compared to the reference group (P < 0.05). Within the hypospadias group, coping style scores did not differ based on severity of hypospadias, timing of surgery or postoperative complications. CONCLUSION: Patients with hypospadias, particularly those with proximal hypospadias or a postoperative complication, more often use an avoiding coping style compared to a reference population. Attention to coping styles during the follow-up of patients with hypospadias might help to improve the QoL in these patients.

Comparison of preputioplasty and circumcision in distal hypospadias correction: long-term follow-up.

OBJECTIVE: A normal penile cosmesis is an important goal in distal hypospadias repair. Depending on cultural standards, repairs are combined with a preputioplasty or circumcision to attain a 'normal' penile appearance. Although short-term complication rates of preputioplasty are available, data on long-term outcomes are scarce. Therefore, this study assessed long-term functional and cosmetic outcomes of distal hypospadias repair with either a preputioplasty or a circumcision. PATIENTS AND METHODS: Eligible for inclusion were patients with distal hypospadias operated in childhood between 1987 and 1993. Complications and reasons for secondary circumcision were extracted from the medical charts. Participants completed a questionnaire including the International Index of Erectile Function (IIEF-15), the International Prostate Symptom score (IPSS), and additional non-validated questions. Penile cosmesis was judged with the Penile Perception Score (PPS), stretched penile length was measured, and uroflowmetry was performed. RESULTS: Of the 86 eligible and traceable patients, 40 (47%) participated; of them, 27 had a preputioplasty and 13 a circumcision. Six patients underwent a secondary circumcision due to a preputial defect (n = 2), unsatisfactory cosmetic result (n = 2), religious reason (n = 1), or phimosis (n = 1). Complication rates were similar in both the groups. Long-term outcomes in the preputioplasty and circumcision group were comparable regarding cosmetic, sexual, and micturition outcomes. CONCLUSIONS: Distal hypospadias correction combined with preputioplasty had complication rates similar to those of hypospadias repair with circumcision. In these patients, preputioplasty had a failure rate of 22%. In both the groups, long-term outcomes of urinary function, sexual function, and cosmesis were good.

Sentinel node biopsy in clinical stage I testicular cancer enables early detection of occult metastatic disease.

OBJECTIVES: To report the long-term results of the sentinel node (SN) approach in patients with clinical stage I testicular tumours in our facility. PATIENTS AND METHODS: We conducted an analysis of 27 consecutive patients suspected of clinical stage I testicular germ cell tumour (TGCT) and treated with an SN procedure at our tertiary referral centre. SNs were identified using lymphoscintigraphy with or without single-photo-emission computed tomography with CT (SPECT/CT). Patients underwent laparoscopic retroperitoneal SN excision with inguinal orchiectomy. Patients with a tumour-positive SN underwent adjuvant treatment. Follow-up was conducted according to then-current guidelines. RESULTS: In two patients, no SNs were visualized on scintigraphy. In the remaining 25 patients, a median (range) of 3 (1-4) SNs per patient were removed. Two patients showed no malignancy on histopathological examination of the testis. Of the 23 patients diagnosed with TGCT (16 seminomas, seven non-seminomas), three (13.0%) had occult metastatic disease. All 23 patients were without evidence of disease at a median (range) follow-up of 63.9 (29.0-143.4) months. CONCLUSION: The SN procedure allows early identification of patients with occult metastatic disease in clinical stage I TGCT, enabling early treatment.

The FUTURE Trial: A Multicenter Randomised Controlled Trial on Target Biopsy Techniques Based on Magnetic Resonance Imaging in the Diagnosis of Prostate Cancer in Patients with Prior Negative Biopsies.

BACKGROUND: Guidelines advise multiparametric magnetic resonance imaging (mpMRI) before repeat biopsy in patients with negative systematic biopsy (SB) and a suspicion of prostate cancer (PCa), enabling MRI targeted biopsy (TB). No consensus exists regarding which of the three available techniques of TB should be preferred. OBJECTIVE: To compare detection rates of overall PCa and clinically significant PCa (csPCa) for the three MRI-based TB techniques. DESIGN, SETTING, AND PARTICIPANTS: Multicenter randomised controlled trial, including 665 men with prior negative SB and a persistent suspicion of PCa, conducted between 2014 and 2017 in two nonacademic teaching hospitals and an academic hospital. INTERVENTION: All patients underwent 3-T mpMRI evaluated with Prostate Imaging Reporting and Data System (PIRADS) version 2. If imaging demonstrated PIRADS ≥3 lesions, patients were randomised 1:1:1 for one TB technique: MRI-transrectal ultrasound (TRUS) fusion TB (FUS-TB), cognitive registration TRUS TB (COG-TB), or in-bore MRI TB (MRI-TB). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Primary (overall PCa detection) and secondary (csPCa detection [Gleason score ≥3+4]) outcomes were compared using Pearson chi-square test. RESULTS AND LIMITATIONS: On mpMRI, 234/665 (35%) patients had PIRADS ≥3 lesions and underwent TB. There were no significant differences in the detection rates of overall PCa (FUS-TB 49%, COG-TB 44%, MRI-TB 55%, p=0.4). PCa detection rate differences were -5% between FUS-TB and MRI-TB (p=0.5, 95% confidence interval [CI] -21% to 11%), 6% between FUS-TB and COG-TB (p=0.5, 95% CI -10% to 21%), and -11% between COG-TB and MRI-TB (p=0.17, 95% CI -26% to 5%). There were no significant differences in the detection rates of csPCa (FUS-TB 34%, COG-TB 33%, MRI-TB 33%, p>0.9). Differences in csPCa detection rates were 2% between FUS-TB and MRI-TB (p=0.8, 95% CI -13% to 16%), 1% between FUS-TB and COG-TB (p>0.9, 95% CI -14% to 16%), and 1% between COG-TB and MRI-TB (p>0.9, 95% CI -14% to 16%). The main study limitation was a low rate of PIRADS ≥3 lesions on mpMRI, causing underpowering for primary outcome. CONCLUSIONS: We found no significant differences in the detection rates of (cs)PCa among the three MRI-based TB techniques. PATIENT SUMMARY: In this study, we compared the detection rates of (aggressive) prostate cancer among men with prior negative biopsies and a persistent suspicion of cancer using three different techniques of targeted biopsy based on magnetic resonance imaging. We found no significant differences in the detection rates of (aggressive) prostate cancer among the three techniques.

The multilayered structure of the human corpus spongiosum.

PURPOSE: Urethral reconstruction is performed in patients with urethral strictures or for correction of congenital disorders. In the case of shortage of tissue, engineered tissue may enhance urethral reconstruction. As the corpus spongiosum (CS) is important in supporting the function of the urethra, tissue engineering of the urethra should be combined with reconstruction of a CS. For that purpose, detailed knowledge of the composition of the CS, more specifically its extracellular matrix (ECM) and vascularization is needed for scaffold design. The objective of this study is to analyze the microarchitecture of the CS through (immuno) histology and scanning electron microscopy (SEM). METHODS: The CS including the urethra of patients undergoing male-to-female genital confirming surgery was harvested. This CS was fixed and processed for either (immuno) histology or for SEM. RESULTS: Four layers could be distinguished in the CS; first a transition zone from urethra epithelium to a collagen rich layer, which was highly vascularized, followed by a second, elastin rich layer. The third layer was formed by veins, arteries and vascular spaces and the last layer showed the transition from this vascular rich region to the collagen rich tunica albuginea. In this layer collagen bundles intertwined with elastic fibres. In the CS different components of the ECM were visible and distinguishable. CONCLUSION: This study provides novel and detailed information on the microarchitecture of the CS and the distribution of vascularization, which is important for scaffold design in tissue engineering.

[The accuracy of patients' perceptions of the risks associated with localised prostate cancer treatments]. / Risicopercepties van mannen met gelokaliseerde prostaatkanker.

OBJECTIVE: To assess the accuracy of patients' perceptions of the risks associated with localised prostate cancer treatments (radical prostatectomy [RP], radiotherapy [RT], and active surveillance [AS]), and to identify correlates of misperceptions. PATIENTS AND METHODS: We used baseline data (questionnaires completed after treatment information was provided but before treatment) of 426 patients with newly diagnosed localised prostate cancer who participated (87% response rate) in a prospective, longitudinal, multicentre study. Patients' pretreatment perceptions of differences in adverse outcomes of treatments were compared to those based on the literature. We used univariate and multivariate linear regression to identify correlates of misperceptions. RESULTS: About two-thirds (68%, n = 211) of the patients did not understand that the risk of disease recurrence is comparable between RP and RT. More than half of the patients did not comprehend that RP patients are at greater risk of urinary incontinence (65%, n = 202) and erectile dysfunction (61%, n = 190), and less at risk of bowel problems (53%, n = 211) compared to RT patients. Many patients overestimated the risk of requiring definitive treatment following AS (45%, n = 157) and did not understand that mortality rates following AS, RP, and RT are comparable (80%, n = 333). Consulting a radiotherapist or a clinical nurse specialist was positively associated with, and emotional distress was negatively associated with, better understanding of the risks (P < 0.05), although effect sizes were small. CONCLUSION: Prior to choosing treatment, most patients with prostate cancer poorly understood the differences in treatment risks. Greater efforts should be made to better understand why these misperceptions occur and, most importantly, how they can be corrected.
