The impact of mpMRI-targeted vs systematic biopsy on the risk of prostate cancer downgrading at final pathology.

PURPOSE: Although targeted biopsies (TBx) are associated with improved disease assessment, concerns have been raised regarding the risk of prostate cancer (PCa) overgrading due to more accurate biopsy core deployment in the index lesion. METHODS: We identified 1672 patients treated with radical prostatectomy (RP) with a positive mpMRI and ISUP ≥ 2 PCa detected via systematic biopsy (SBx) plus TBx. We compared downgrading rates at RP (ISUP 4-5, 3, and 2 at biopsy, to a lower ISUP) for PCa detected via SBx only (group 1), via TBx only (group 2), and eventually for PCa detected with the same ISUP 2-5 at both SBx and TBx (group 3), using multivariable logistic regression models (MVA). RESULTS: Overall, 12 vs 14 vs 6% (n = 176 vs 227 vs 96) downgrading rates were recorded in group 1 vs group 2 vs group 3, respectively (p < 0.001). At MVA, group 2 was more likely to be downgraded (OR 1.26, p = 0.04), as compared to group 1. Conversely, group 3 was less likely to be downgraded at RP (OR 0.42, p < 0.001). CONCLUSIONS: Downgrading rates are highest when PCa is present in TBx only and, especially when the highest grade PCa is diagnosed by TBx cores only. Conversely, downgrading rates are lowest when PCa is identified with the same ISUP through both SBx and TBx. The presence of clinically significant disease at SBx + TBx may indicate a more reliable assessment of the disease at the time of biopsy potentially reducing the risk of downgrading at final pathology.

Laryngeal office-based procedures: A safe approach.

PURPOSE: Laryngeal surgeries using a flexible nasopharyngoscope equipped with an operative channel has gained popularity, with gradual increase in the variety of interventional office-based procedures, under local anesthesia. The purpose of this study is to analyze the tolerance of such procedures. MATERIALS AND METHODS: Retrospective cohort study. 337 cases were performed during 2 years. We collected the following data: type of pathology, type of procedure and modalities of anesthesia, adverse events. RESULTS: 19 % of the visits were for the purpose of Biopsy, 65 % for an injection, and Trublue Laser was utilized in 12 % of the procedures. Regarding the pathologies, 27 % were vocal fold paralysis, 18 % leukoplakia or another suspicious lesion, 15 % recurrent respiratory papillomatosis, 13 % neuromuscular disorder, 9 % vocal fold scarring, 7 % vocal cord atrophy and 6 % had an inflammatory presentation. Side effects were documented in 26 visits (7.7 %) and were minor in almost all the encounters: they included strong reflexive cough, deep throat pain, discomfort, gag reflex, anxiety, vagal discomfort, malaise, hypersalivation, nose pain, labile hypertension. More severe side effects were very rare and included septal wound and epistaxis, erythematous rash, dyspnea, and transient dysarthria. 13 procedures were either aborted, or canceled at initial steps, due to inability of the patient to tolerate the procedure and were rescheduled for general anesthesia. 97 % of the cases were released home after 1 h of surveillance. CONCLUSION: Office-based flexible interventional laryngoscopy under local anesthesia is a safe and well-tolerated procedure, with abundance of various interventions feasible on ambulatory, office-based setup.

A monocentric retrospective analysis about the effects of COVID-19 pandemic on emergency general surgery consultations.

OBJECTIVE: The pandemic effects due to the coronavirus SARS-CoV-2 caused a health emergency. We decided to carry out a study with the aim to investigate the changes in patients' tendencies for admission to the emergency department for surgical diseases, and the related hospitalizations and urgent surgery rates. PATIENTS AND METHODS: We carried out a retrospective, observational study on patients who received emergency general surgery consultation at our University Hospital during the two COVID-19 pandemic periods and on the same dates one year before. The patients' demographic characteristics, their hospitalization in surgical department and the data about those who underwent urgent surgery were retrospectively recorded. RESULTS: In the period March-April 2020 there were 95 surgical visits recorded; among these patients, 25% required hospitalization and 12.63% underwent urgent surgery. In the period November-December-January 2020-2021 there were 156 surgical consultations, of which 35.26% required hospitalization and 21.15% underwent urgent surgery. In both considered periods we found that the number of surgical consultations decreased compared to the same periods of the previous year. Moreover, we found a higher rate of hospitalization and need for urgent surgery. CONCLUSIONS: We documented a significant reduction in the overall number of surgical consultations and an increase of hospitalization and urgent surgery rates.

Impact of endometriosis on obstetric outcome after natural conception: a multicenter Italian study.

PURPOSE: To evaluate obstetric outcome in women with endometriosis who conceive naturally and receive standard obstetric care in Italy. METHODS: Cases were consecutive women with endometriosis managed in eleven Italian referral centers. Controls were women in whom endometriosis was excluded. All women filled in a questionnaire addressing previous natural pregnancies. Marginal logistic regression models were fitted to evaluate the impact of endometriosis on obstetric outcome. A post hoc analysis was performed within the endometriosis group comparing women with severe adenomyosis versus women with absent or mild adenomyosis. RESULTS: Three hundred and fifty-five pregnancies in endometriosis group and 741 pregnancies in control group were included. Women with endometriosis had a higher risk of preterm delivery < 34 weeks (6.4% vs 2.8%, OR 2.42, 95% CI 1.22-4.82), preterm delivery < 37 weeks (17.8% vs 9.7%, OR 1.98, 95% CI 1.23-3.19), and neonatal admission to Intensive Care Unit (14.1% vs 7.0%, OR 2.04, 95% CI 1.23-3.36). At post hoc analysis, women with endometriosis and severe adenomyosis had an increased risk of placenta previa (23.1% vs 1.8%, OR 16.68, 95% CI 3.49-79.71), cesarean delivery (84.6% vs 38.9%, OR 8.03, 95% CI 1.69-38.25) and preterm delivery < 34 weeks (23.1% vs 5.7%, OR 5.52, 95% CI 1.38-22.09). CONCLUSION: Women with endometriosis who conceive naturally have increased risk of preterm delivery and neonatal admission to intensive care unit. When severe adenomyosis is coexistent with endometriosis, women may be at increased risk of placenta previa and cesarean delivery. TRIAL REGISTRATION: Clinical trial registration number: NCT03354793.

The early prediction of mortality in acute cholecystitis: Temperature, Neutrophils and Multiple organ failure (TNM) score.

OBJECTIVE: Acute Cholecystitis (AC) accounts for a significant proportion of patients presenting to the Emergency Department with abdominal pain. We suggest grading the severity of AC with a simple system: TNM, an acronym borrowed by cancer staging where T indicated Temperature, N neutrophils and M Multiple organ failure. This retrospective-prospective observational study evaluates the predictive value of TNM score on mortality of patients with AC. PATIENTS AND METHODS: TNM was developed in a training cohort of 178 patients with AC who underwent cholecystectomy from February 2005 to December 2012 (retrospectives data). To verify the prognostic value of TNM score, we prospectively recruited 172 patients who were consecutively included and treated from January 2013 to July 2020 as the validation cohort. After defining the categories T, N and M, patients were grouped in stages. The variables analyzed were age, sex, American Society of Anesthesiologists (ASA) score, blood transfusion, temperature, neutrophils count, preoperative organ failure, immune-compromised status, stage. RESULTS: In the training cohort TNM staging was: none patient at stage 0; 6 patients at stage I; 71 patients at stage II; 71 patients at stage III; 30 patients at stage IV. Death occurred in 51 patients. ASA score, neutrophils count, preoperative organ failure, stage III-IV emerged as statistically significant different prognostic factors. ASA score (III-IV) and stage (III-IV) were significant independent predictors of post-operative mortality in multivariate analysis. Comparable results were observed in the validation cohort. CONCLUSIONS: TNM classification is very easy to use; it helps to define the mortality risk and it is useful to objectively compare patients with AC.

Endometriosis: seeking optimal management in women approaching menopause.

The incidence of endometriosis in middle-aged women is not minimal compared to that in the reproductive age group. The treatment of affected women after childbearing age to the natural transition toward menopause has received considerably poor attention. Disease management is problematic for these women due to increased contraindications regarding hormonal treatment and the possibility for malignant transformation, considering the increased cancer risk in patients with a long-standing history of the disease. This state-of-the-art review aims for the first time to assess the benefits of the available therapies to help guide treatment decisions for the care of endometriosis in women approaching menopause. Progestins are proven effective in reducing pain and should be preferred in these women. According to the international guidelines that lack precise recommendations, hysterectomy with bilateral salpingo-oophorectomy should be the definitive therapy in women who have completed their reproductive arc, if medical therapy has failed. Strict surveillance or surgery with removal of affected gonads should be considered in cases of long-standing or recurrent endometriomas, especially in the presence of modifications of ultrasonographic cyst patterns. Although rare, malignant transformation of various tissues in endometriosis patients has been described, and management is herein discussed.

[Evaluation of a prostate cancer E­health tutorial : Development and testing of the website prostata-information.ch]. / Evaluation eines Online-Tutorials zum Prostatakarzinom : Entwicklung und Überprüfung der Seite prostata-information.ch.

BACKGROUND: Due to the multitude of therapy options, the treatment decision after diagnosis of localized prostate cancer is challenging. Compared to printed booklets, web-based information technology offers more possibilities to tailor information to patients' individual needs. OBJECTIVES: To support the decision-making process as well as the communication with patients, we developed an online tutorial in a systematic process in the German-speaking part of Switzerland and then tested it in a pilot study. The study investigated users' satisfaction, the coverage of information needs, the preparation for decision making, and the subjective quality of the decision. MATERIALS AND METHODS: Based on already existing information material, the online tutorial was developed in an iterative process using focus groups with patients and urologists. For the following evaluation in eight clinics a total of 87 patients were invited to access the platform and participate in the study. Of these patients, 56 used the tutorial and 48 answered both surveys (the first one 4 weeks after the first login and the second one 3 months after treatment decision). The surveys used the Preparation for Decision Making Scale (PDMS), the Decisional Conflict Scale (DCS), and the Decisional Regret Scale (DRS). RESULTS AND CONCLUSION: Satisfaction with the tutorial is very high among patients with newly diagnosed localized prostate cancer. Users find their information needs sufficiently covered. Three months after the decision they felt that they were well prepared for the decision making (mean PDMS 75, standard deviation [SD] 23), they had low decisional conflict (mean DCS 9.6, SD 11), and almost no decisional regret (mean DRS 6.4, SD 9.6). Based on these findings, further use of the tutorial can be recommended.

Cell therapy and vocal fold scarring.

Vocal fold microstructure is complex and can be affected by laryngeal microsurgery, inducing scarring that prevents mechanical uncoupling of epithelium and muscle, leading to vibration disorder and disabling dysphonia. Treatment options presently are few, and often without efficacy for vibration, having only an impact on volume to reduce glottal closure defect. The present review of the literature had two aims: (i) to report the current state of the literature on cell therapy in vocal fold scarring; and (ii) to analyze the therapeutic interest of the adipose-derived stromal vascular fraction in the existing therapeutic armamentarium. A PubMed® search conducted in September 2016 retrieved English or French-language original articles on the use of stem cells to treat vocal fold scarring. Twenty-seven articles published between 2003 and 2016 met the study selection criteria. Mesenchymal stem cells were most widely used, mainly derived from bone marrow or adipose tissue. Four studies were performed in vitro on fibroblasts, and 18 in vivo on animals. End-points comprised: (i) scar analysis (macro- and micro-scopic morphology, viscoelastic properties, extracellular matrix, fibroblasts); and (ii) assessment of stem cell survival and differentiation. The studies testified to the benefit of mesenchymal stem cells, and especially those of adipose derivation. The stromal vascular fraction exhibits properties that might improve results by facilitating production logistics.

The surgical management of patients with clinical stage T4 bladder cancer: A single institution experience.

INTRODUCTION: Patients with clinical T4 (cT4) bladder cancer (BCa) infrequently undergo radical cystectomy (RC). We investigated the reliability of preoperative clinical staging, perioperative and survival outcomes in patients treated with RC due to cT4a-b BCa disease at a single tertiary care institution. METHODS: The study relied on 917 BCa patients treated with RC and pelvic lymph node dissection (PLND) at a single institution between January 1995 and December 2012. We compared the accuracy of the clinical assessment with final pathology results. Moreover, we evaluated perioperative outcomes, complication rates and survival after surgery. RESULTS: The median follow-up was 62 months. Overall, 74 (8.1%) patients presented cT4 stage at preoperative evaluation. Conversely, a pathological T4 disease was confirmed only in 68.9% patients staged initially as cT4. No differences were recorded in complications, 30 days readmission or 30 days death rates between cT1-T3 vs. cT4a vs. cT4b (p > 0.1). At multivariable Cox regression analyses predicting cancer specific mortality, clinical T4 stage vs. clinical T1-2, clinical T3 stage vs. clinical T1-2 and age were predictors of worst survival after RC (all p < 0.04). CONCLUSIONS: We recorded poor concordance between preoperative imaging and pathology in cT4 patients. No differences in major perioperative outcomes and acceptable survival expectancies were reported in patients treated for cT4 disease.

Developmental programming of polycystic ovary syndrome (PCOS): prenatal androgens establish pancreatic islet α/ß cell ratio and subsequent insulin secretion.

Exogenous androgenic steroids applied to pregnant sheep programmes a PCOS-like phenotype in female offspring. Via ultrasound guidance we applied steroids directly to ovine fetuses at d62 and d82 of gestation, and examined fetal (day 90 gestation) and postnatal (11 months old) pancreatic structure and function. Of three classes of steroid agonists applied (androgen - Testosterone propionate (TP), estrogen - Diethystilbesterol (DES) and glucocorticoid - Dexamethasone (DEX)), only androgens (TP) caused altered pancreatic development. Beta cell numbers were significantly elevated in prenatally androgenised female fetuses (P = 0.03) (to approximately the higher numbers found in male fetuses), whereas alpha cell counts were unaffected, precipitating decreased alpha:beta cell ratios in the developing fetal pancreas (P = 0.001), sustained into adolescence (P = 0.0004). In adolescence basal insulin secretion was significantly higher in female offspring from androgen-excess pregnancies (P = 0.045), and an exaggerated, hyperinsulinaemic response to glucose challenge (P = 0.0007) observed, whereas prenatal DES or DEX treatment had no effects upon insulin secretion. Postnatal insulin secretion correlated with beta cell numbers (P = 0.03). We conclude that the pancreas is a primary locus of androgenic stimulation during development, giving rise to postnatal offspring whose pancreas secreted excess insulin due to excess beta cells in the presence of a normal number of alpha cells.

Bronchial blockers under pressure: in vitro model and ex vivo model.

BACKGROUND: Pressures (Pe) exerted by bronchial blockers on the inner wall of the bronchi may cause mucosal ischaemia. Our aims were as follows: (i) to compare the intracuff pressure (Pi) and Pe exerted by commercially available bronchial blockers in an in vitro and an ex vivo model; (ii) to investigate the influence of both the inflated intracuff volume and cuff diameter on Pe; and (iii) to estimate the minimal sealing volume (VSmin) and the corresponding Pe for each bronchial blocker studied. METHODS: The Pe exerted by seven commercial bronchial blockers was measured at different inflation volumes using a custom-designed system using in vitro and ex vivo animal models with two internal diameters (12 and 15 mm). RESULTS: In the same conditions, Pi was significantly lower than Pe (P<0.05), and Pe was higher in the in vitro model than in the ex vivo model. The Pe increased with the inflated volume, with use of the small-diameter model (P<0.05). Ex vivo models needed a higher minimal sealing volume than the in vitro models, and this volume increased with the diameter (e.g. the VSmin at a positive pressure of 25 cm H2O required a Pe ranging from 12 to 78 mm Hg on the 15 mm ex vivo model and from 66 to 110 mm Hg on the 12 mm ex vivo model). CONCLUSIONS: The Pi cannot be used to approximate Pe. The diameter of the model, the inflated volume, and the bronchial blocker design all influence Pe. A pressure higher than the critical ischaemic threshold (i.e. 25 mm Hg) was needed to prevent air leak around the cuff in the in vitro and ex vivo models.

Bipolar versus monopolar transurethral resection of the prostate: a prospective randomized trial focusing on bleeding complications.

PURPOSE: We compare monopolar vs bipolar transurethral resection of the prostate in patients with benign prostatic hyperplasia, focusing on functional outcomes as well as rates of bleeding complications and the transurethral resection syndrome. MATERIALS AND METHODS: A total of 137 patients with benign prostatic hyperplasia (mean age 67 years, range 47 to 91) were prospectively randomly assigned to undergo monopolar (67) or bipolar (70) transurethral resection of the prostate. Patient characteristics of the 2 groups were similar. Hemoglobin (as a marker of blood loss) was measured preoperatively and perioperatively. I-PSS, I-PSS-QoL score, maximal flow rate and post-void residual urine volume were assessed preoperatively and 3 and 12 months postoperatively. Duration of surgery, indwelling catheter use and hospitalization were also documented, as were postoperative clot retention requiring removal by catheterization or surgery, and rates of bladder neck and/or urethral strictures. RESULTS: No significant perioperative differences were found in duration of surgery, catheterization or hospitalization, or in blood loss or rates of blood transfusion and transurethral resection syndrome. Postoperatively there were no significant differences in I-PSS or I-PSS-QoL scores, or rates of rehospitalization, clot retention, blood transfusions, reoperation or urethral strictures. However, bladder neck stricture occurred significantly more often in the bipolar group (8.5% vs 0%, p = 0.02). The 3 and 12-month followup showed significant and equal improvement in micturition in the 2 groups. CONCLUSIONS: Bipolar and monopolar transurethral resection of the prostate are effective and safe techniques for the surgical treatment of benign prostatic hyperplasia. The only significant difference between them was a significantly higher rate of bladder neck strictures with bipolar resection of the prostate.

Design and characterization of a measurement system for monitoring pressure exerted by bronchial blockers: In vitro trials.

Bronchial blockers (BBs) allow occluding the bronchial duct and collapsing the "dependent" lung in a number of thoracic surgery. The occlusion is obtained through a cuff that, inflated with a proper air volume, exerts a pressure, Pe, on the inner wall of the mainstem bronchus. In this work a measurement chain, based on two piezorestistive force sensors, was developed and calibrated to measure Pe exerted by six BBs, as a function of inflated volume on in vitro models (two latex ducts with diameters similar to the ones of the adult mainstem bronchi: 12 mm and 15 mm). Pe showed wide changes considering different BBs, and significantly increases with the decrease of the model's diameter, at the same inflated volume. Lastly, the minimum occlusive volume (MOV) to sail the two models was estimated for each BB. These experiments were performed by applying a pressure difference across the cuff of 25 cmH2O, in order to simulate the worst condition in a clinical scenario. Results show that MOV depends on both the type of BB and the duct diameter. The knowledge of this volume allows estimating the minimum value of Pe exerted by BBs to avoid air leakage.

One- vs 4-week stent placement after laparoscopic and robot-assisted pyeloplasty: results of a prospective randomised single-centre study.

OBJECTIVES: To determine whether 1-week stenting of the pelvi-ureteric anastomosis of laparoscopic or robot-assisted pyeloplasty is as effective as 4-week stenting, based on their respective success rates. PATIENTS AND METHODS: A total of 100 patients with pelvi-ureteric junction obstruction were treated by Anderson-Hynes pyeloplasty and the anastomosis was stented using a 6-F JJ catheter for either 1 week (1W series) or 4 weeks (4W series), based on a randomisation protocol. Postoperative follow-up was performed at 3 months using intravenous urography (IVU), at 6 months using diuretic renography and at 1, 3 and 5 years using ultrasonography. Statistical analysis was performed using a one-sided Z-test, Pearsons's chi-squared test and a Wilcoxon rank sum test. RESULTS: The primary outcome measure, success rate, which was defined as no obstruction on IVU and diuretic renography, was 100% in the 1W series and not inferior to the success rate of 98% in the 4W series (P = 0.006). The following secondary outcome measures were not significantly different between the 1W and the 4W series with regard to residual symptoms (10 vs 6%; P = 0.48), rate of complications (4 vs 6%; P = 0.65), need for synchronous robot-assisted pyelolithotomy (4 vs 8%; P = 0.47), improvement in split renal function (1 vs 0%; P = 0.59) and duration of surgery (200 vs 192 min; P = 0.87). Only length of hospital stay was significantly different; this was shorter in the 1W series (5 vs 6 days; P = 0.01). CONCLUSIONS: Stenting of the pelvi-ureteric anastomosis after laparoscopic or robot-assisted pyeloplasty for 1 week is as effective as stenting for 4 weeks. Both procedures, laparoscopic or robot-assisted pyeloplasty have an excellent success rate.

In vitro activity of disinfectants against Aspergillus spp

Fungi of the Aspergillus genus are widespread and contaminate the environment. Thousands of conidia are released from each phialide and dispersed in the air every day. These fungi are considered important mycose-causing agents in hospitals. Due to this, research to determine prevalent fungi from the Aspergillus genus in hospital environments, and an adequate disinfection program in these areas is are needed. This study evaluated the susceptibility of Aspergillus spp. isolated from a veterinary environment against four disinfectants. Successive dilutions of disinfectants (log2) were used according to CLSI M38-A2 microdilution technique adapted to chemical agents against 18 isolates of this genus. After 72 hours of incubation, the Minimum Inhibiting Concentration and Minimum Fungicidal Concentration capable of inhibiting 50% and 90% of the isolates were determined. Chlorexidine-cetrimine, benzalconium chloride and a chlorophenol derivative proved to be effective against all isolates with a lower MIC than that suggested by the manufacturer, except for the A. flavus strain. Sodium hypochlorite was ineffective against three A. fumigatus, three A. flavus and one A. niger isolate. These results demonstrated that all studied disinfectants were effective against environmental isolates, with the exception of sodium hypochlorite, which showed lower effectiveness.

Paediatric adenoidectomy: endoscopic coblation technique compared to cold curettage.

The aim of our study was to assess the efficacy and safety of endoscopic coblator adenoidectomy compared to cold curettage in paediatric patients. Forty homogeneous children (4-16 years of age) with adenoid hypertrophy were divided in 2 groups to receive adenoidectomy using cold curettage (A) or coblator (B). After surgery the following outcomes were evaluated: pain score on first day, days reporting pain, analgesic days, liquid diet days, absent from school days, pain score, days with nausea, days with fever, endoscopic adenoid grade and intraoperative bleeding. Forty days after surgery, basal rhinomanometry and nasal decongestion test were measured. The coblation group reported significantly less pain on the first post-operative day, days reporting pain, analgesic days, liquid diet days and absent school days. Patients in group A showed a higher grade of adenoid persistence by rhinoendoscopy, with high values of nasal resistances at the rhinomanometry even after nasal decongestion, consistent with greater adenoid persistence after cold curettage causing air flow obstruction even after turbinate decongestion. Intra-operative bleeding during coblation was significantly less compared the group undergoing cold curettage. Coblator treatment significantly improved patient recovery compared to curettage. Endoscopic coblation adenoidectomy ensures complete removal of adenoids and reduces postoperative adenoid grade. It can also be considered safer because it is under endoscopic control and can reach the cranial portion of the adenoid and its intranasal extension.

[Tamoxifen, endometrial cancer risk and liquid based cytology. A paradigmatic case]. / Tamoxifene, rischio oncologico endometriale e citologia in fase liquida. Un caso clinico paradigmatico.

Long-term users of tamoxifen (TMX) are at increased risk for developing endometrial cancer. Early diagnosis is mainly based on transvaginal scan (TVS) and hysteroscopy with endometrial biopsy. Nevertheless, TVS does not provide a definitive diagnosis in most cases, particularly due to its high false-positive rate. In addition TMX related changes, such as "pseudocistic" pattern, affect endoscopic evaluation of the endometrium and biopsy sampling (in particular blind procedures) frequently yields insufficient tissue for diagnosis. The cause of the high inadequacy rate of endometrial biopsies in women on TMX might be related to the increase in endometrial fibrous component. The present case emphasizes the main difficulties in surveillance and early diagnosis of endometrial pathologies in TMX users. Liquid-based endometrial cytology played a determinant role in the diagnostic pathway of this patient. We believe it could be used solely or in association with TVS leading to many advantages in the surveillance of women receiving TMX.

When and how should we test the tightness of the vesicourethral anastomosis after retropubic radical prostatectomy?

OBJECTIVE: To determine when the vesicourethral anastomosis (VUA) becomes tight after retropubic radical prostatectomy (RRP) and if an additional lateral view cystography provides significantly more information than the only anterior-posterior view. PATIENTS AND METHODS: Pressure-controlled cystography with anterior-posterior and lateral views was performed on postoperative days (POD) 3, 6 and 9 and evaluated in 100 consecutive patients after RRP. RESULTS: On POD 3, 6 and 9, 82, 80 and 82% of all VUA, respectively, were tight. 85% of all tight VUA on POD 3 remained tight on POD 6 and 9. Of the 52 extravasations in a total of 300 cystographies, 65% were recognizable in the anterior-posterior as well as in the lateral view cystography, 6% were seen only in the anterior-posterior view and 29% only in the lateral view. CONCLUSIONS: The VUA after RRP is tight in about 80% of the cases on POD 3, 6 and 9. A tight VUA on POD 3 does not exclude later extravasation on POD 6 and 9 (14%). About one third (29%) of all extravasations of VUA are seen only in the lateral view cystography after RRP.
