[Hospitalization rate in relation to severe complications of transrectal prostate biopsy: About 2715 patients biopsied]. / Taux d'hospitalisations en rapport avec des complications sévères des biopsies de prostate transrectales : à propos de 2715 patients biopsiés.

MAIN OBJECTIVE: To identify hospitalizations directly related to a complication occurring within 30 days following a transrectal prostate biopsy (PBP). SECONDARY OBJECTIVES: Overall hospitalization rates, mortality rates, potential predisposing factors for complications. PATIENTS AND METHODS: Single-center study including all patients who underwent PBP between January 2005 and January 2012. Any hospitalization occurring within 30 days of the PBP for urgent motive was considered potentially attributable to biopsy. We identified the reason for hospitalization with direct complications (urinary infection or fever, rectal bleeding, bladder caillotage, retention) and indirect (underlying comorbidities decompensation) of the biopsy. The contributing factors were anticoagulant or antiplatelet treatment well as waning immunity factors (corticosteroid therapy, HIV, chemotherapy or immunodulateur). RESULTS: Among 2715 men who underwent PBP, there were 120 (4.4%) hospitalizations including 28 (1.03%) caused by the biopsy. Twenty-five (0.92%) were related to a direct complication of biopsy: 14 (56%) for urinary tract infection or fever including 1 hospitalization in intensive care, 5 (20%) for rectal bleeding which required several transfusions 1, 10 (40%) urinary retention and 3 (0.11%) for an indirect complication (2 coronary syndromes and 1 respiratory failure). Several direct complications were associated in 3 cases. Only two hospitalizations associated with rectal bleeding were taking an antiplatelet or anticoagulant. There was no association between hospitalization for urinary tract infections and a decreased immune status. The first death observed in our study occurred at D31 of pulmonary embolism (advanced metastatic patient with bladder cancer). Twenty (60.6%) patients urgently hospitalized did not have prostate cancer. CONCLUSIONS: Within this large sample of patients the overall rate of hospitalization due to the realization of a PBP was 1%. It has not been found predictive of complications leading to hospitalization. LEVEL OF EVIDENCE: 4.

Urinary PCA3 to predict prostate cancer in a cohort of 1015 patients.

AIM: To evaluate the performance of urinary PCA3 test to predict prostate biopsy outcome in a large French cohort. PATIENTS AND METHODS: A urine sample was prospectively obtained in 1015 patients undergoing prostate biopsies to determine the PCA3 score. The predictive value of PCA3 was explored using receiver operating characteristic curve analysis (ROC), multivariable logistic regression analysis and decision curve analysis. RESULTS: The median PCA3 score was significantly higher in patients with positive biopsies. The PCA3 score AUC was 0.76 (0.73-0.79), significantly higher than that of PSA (0.55; 0.51-0.58). At the cut-off of 35, sensitivity was 68 %, specificity 71 %, positive and negative predictive values 67 % and 71 %, and accuracy 69 %. Using multivariate analysis, PCA3 score appeared as an independent predictor of biopsy outcome and its addition to a base model including usual clinico-biological parameters resulted in a significant increase in predictive accuracy. At the cut-off of 20, about 1/2 of the eventual useless biopsies would have been avoided while ignoring 7 % of cancers with Gleason score ≥ 7. PCA3 score did not correlate to Gleason score but correlated to tumor volume (proportion of invaded cores). CONCLUSION: Urinary PCA3 is a useful test with high diagnostic performance for early prostate cancer diagnosis. Its correlation with cancer aggressiveness seems rather represented by a link to prostate volume than Gleason score.

Nephron sparing surgery for De Novo kidney graft tumor: results from a multicenter national study.

Nephron sparing surgery (NSS) results in the transplanted population remain unknown because they are only presented in small series or case reports. Our objective was to study renal sparing surgery for kidney graft renal cell carcinomas (RCC) in a multicenter cohort. Data were collected from 32 French transplantation centers. Cases of renal graft de novo tumors treated as RCC since the beginning of their transplantation activity were included. Seventy-nine allograft kidney de novo tumors were diagnosed. Forty-three patients (54.4%) underwent renal sparing surgery. Mean age of grafted kidneys at the time of diagnosis was 47.5 years old (26.1-72.6). The mean time between transplantation and tumor diagnosis was 142.6 months (12.2-300). Fifteen tumors were clear cell carcinomas (34.9%), and 25 (58.1%) were papillary carcinomas. Respectively, 10 (24.4%), 24 (58.3%) and 8 (19.5%) tumors were Fuhrman grade 1, 2 and 3. Nine patients had postoperative complications (20.9%) including four requiring surgery (Clavien IIIb). At the last follow-up, 41 patients had a functional kidney graft, without dialysis and no long-term complications. NSS is safe and appropriate for all small tumors of transplanted kidneys with good long-term functional and oncological outcomes, which prevent patients from returning to dialysis.

Additional value of PCA3 density to predict initial prostate biopsy outcome.

PURPOSE: Similar to prostate-specific antigen (PSA) density, PCA3 density (PCA3D: ratio of urinary PCA3 score/prostate volume) can be calculated, but whether it can be an aid to decide biopsy in patients at risk of prostate cancer (PCa) is uncertain. The objective was to demonstrate that PCA3D provides better specificity than PCA3 in predicting initial prostate biopsy outcome. METHODS: Serum and urine samples were obtained from 595 consecutive patients scheduled for initial prostate biopsy. The urinary PCA3 test was performed before biopsy. Additional measures were prostate volume, PSA density (PSAD) and PCA3D. Multivariate logistic regression models including baseline characteristics and the markers were evaluated. The presumed net benefit was assessed through decision curve analyses. RESULTS: PSAD and PCA3D performed better than PSA and PCA3 score, respectively. PCA3D provided the best specificity (76 %). The best calculated cutoff for PCA3D was 1. The risk of positive biopsy significantly increased to 70 % if PCA3D ≥ 1 versus 29 % if PCA3D was <1. Using a cutoff at 0.5 for PCA3D, biopsies could have been avoided in up to 52 % of the patients without PCa while missing 15 % of any PCa and 10 % of PCa with Gleason score ≥7. Decision curve analyses showed that PSAD was the best predictor of Gleason score at biopsy while PCA3D best predicted the proportion of invaded cores. CONCLUSIONS: PCA3D showed a significant increase in specificity when compared with PSA, PSAD and PCA3. PCA3D can be considered an easy-to-use mini-nomogram with a 70 % risk of positive initial biopsy when PCA3D > 1, i.e., PCA3 score > prostate volume.

Diagnostic terminology for urinary cytology reports including the new subcategories 'atypical urothelial cells of undetermined significance' (AUC-US) and 'cannot exclude high grade' (AUC-H).

OBJECTIVE: We studied whether atypical, non-superficial urothelial cells (AUC) could be separated into new subcategories including AUC 'of undetermined significance' (AUC-US) and 'cannot exclude high grade'' (AUC-H) in order to help to standardize urine cytopathology reports, as it is widely accepted in the Bethesda system for gynaecological cytopathology. METHODS: We investigated whether AUC-US and AUC-H, defined by distinctive cytological criteria, might be separated with statistical significance according to actual diagnosis and follow-up data. A series of 534 cyto-histological comparisons taken in 139 patients, including 221 AUC at various steps of their clinical history was studied. There were 513 (96.1%) postcystoscopy and 469 (87.8%) ThinPrep® liquid-based specimens (95.9% and 89.1% of AUC cases, respectively). Patients viewed between 1999 and 2011 had histological control in a 0- to 6-months delay and were followed-up during an additional 5.9 ± 9.2 (0- to 56-) months period. RESULTS: The 221 AUC represented 0.8-2% of the specimens viewed during the study period. Among AUC-H cases, 70 out of 185 (37.8%) matched with high-grade lesions, compared with 3 of 38 (8.3%) of AUC-US cases (P = 0.0003). Conservatively treated patients with AUC-H more frequently developed high-grade lesions than those with AUC-US (54.1% versus 16.7%, P = 0.0007) with a 17.6-months mean delay. Nuclear hyperchromasia, a nuclear to cytoplasm (N/C) ratio > 0.7 and the combination of both were the more informative diagnostic criteria, all with P < 0.01. CONCLUSION: We conclude that the new subcategories could help to standardize urine cytopathology reports and contribute to the patient's management, provided it is validated by multicentric studies.

[Millin adenomectomy in the era of laser enucleation: results in a series of 240 cases]. / L'adénomectomie selon Millin à l'heure de l'énucléation laser : résultats d'une série de 240 cas.

INTRODUCTION: New techniques have been proposed for the surgical treatment of benign prostatic hypertrophy (BPH): laser enucleation and laparoscopic adenomectomy. The objective of this retrospective study was the comparison of the results of Millin adenomectomy realized under contemporary medical conditions, with the results of laser enucleation and laparoscopic adenomectomy. METHOD: Two hundred and forty consecutive Millin adenomectomy cases performed between January 2004 and December 2008 were analyzed. Patient evaluation before operation consisted in IPSS score, quality of life score, maximum flow rate (Qmax), post-void residual volume (PRV), total prostate volume (TPV) performed under trans-rectal ultrasound. Operation duration, adenoma weight, blood loss during operation, transfusion rate, duration of Foley catheterization, duration of hospital stay, and immediate postoperative complications according to Clavien classification were reported. Each patient was systematically controlled at 3 months and was invited by mail for a second control in 2012. Each of the two outpatient controls consisted in the realization of an IPSS, quality of life score, Qmax and PRV. Our results were compared to contemporary results published concerning open adenomectomy and new techniques of adenomectomy. RESULTS: Mean age was 69 years, TPV before operation 111 cc, adenomectomy specimen weight 82 gr, blood loss during operation 246 mL, transfusion rate 6 %, operation duration 88 min, Foley catheterization duration 3.8 days, mean hospital stay 5.6 days. Clinical results at 3 months were: IPSS decrease from 25 to 5 points, quality of life score decrease from 5 to 0.7 points, Qmax increase from 6.5 to 22 mL/sec, PRV decrease from 115 to 7.5 mL. According to the use of either the classical classification or of Clavien classification, the rate of early complications varied respectively from 36 to 49 %. No Clavien grade 4 or 5 complication was observed. Long-term results in 137 (57 %) of the patients with a mean age of 80 years, 5 years medial control (4; 8) after adenomectomy showed an IPSS varying from 2.5 to 6.6 points according to follow-up length, quality of life score varying from 0 to 1.2 points, Qmax varying from 13 to 23 mL/sec, PRV varying from 0 to 25 mL. CONCLUSION: The lack of exhaustivity of the results and the absence of use of Clavien classification rendered difficult any comparison between the different techniques. Urologist motivation in favor of a given technique represented a bias difficult to bypass, even with the realization of a randomized study comparing two techniques. Today, Millin operation still represented the gold standard for the evaluation of new techniques in the surgical treatment of large volume BPH. LEVEL OF EVIDENCE: 5.

[Does PCA3 score and prostatic MRI help selection of patients scheduled for initial prostatic biopsy?]. / Le score PCA3 et l'IRM prostatique permettent-ils de sélectionner les patients candidats a une première série de biopsies prostatiques ?

INTRODUCTION: Determinate if the adjunction of PCA3 score and/or prostatic MRI can improve the selection of the patients who have an indication of first prostate biopsy. PATIENTS AND METHODS: Multiparametric prostatic MRI and PCA3 score were made before biopsy to men scheduled for initial prostate biopsy for abnormal digital rectal examination and/or PSA superior to 4 ng/mL. T2-weighted imaging, diffusion-weighted imaging and dynamic contrast-enhanced imaging looked for suspect target classified on a scale of four. It was a prospective, single centre study. The diagnostic accuracy of PCA3 score and MRI was to evaluate in comparison with biopsy results. RESULTS: Sixty-eight patients were included, median PSA was 5.2 ng/mL (3.2-28). Negative predictive value (NPV) of MRI score 0, 1 and 2 were respectively 80%, 43% and 69%. Positive predictive value (PPV) of MRI score 3 and 4 were 50% and 81%. The PCA3 cutoff with best accuracy was 21 (Se: 0.91; Sp: 0.50). Only one patient with positive biopsy (0.5mm of Gleason score 3+3) had negative MRI and PCA3 inferior to 21. CONCLUSION: MRI and PCA3 score in association allowed, in this study, to consider reduction of unnecessary initial biopsy without ignoring potential aggressive tumor.

[Economic and organizational impact of the use of a disposable sheath with a flexible cystoscope]. / Cystoscope flexible à gaine stérile à usage unique: impact organisationnel et économique et sécurité bactériologique.

PURPOSE: To assess both economical and organizational impact as well as bacteriologic safety of a flexible cystoscope with sterile disposable sheath (FCSDS) compared to standard flexible cystoscopy (SFC) in two French urologic academic units. PATIENTS: Two-center prospective study, comparing the use of the FCSDS to the SFC on two consecutive periods of time. Two hundred and five patients were included and divided into each group. Duration procedures and costs were analysed in the two techniques. The urinary tract infection rate was also described. A dedicated sheaths leaks test after use was performed systematically. RESULTS: The preparation time of the fibroscope was longer for the sheathed cystoscopy group: 16.2 minutes versus 10.9 minutes for the standard group. The mean duration of disinfection was significantly shorter for the sheathed cystoscopy group: 53.8 minutes saved compared to the standard group; 99.01% of the tested sheaths, after their use, had no breaches. Urinary tract infections rate were similar in the two groups. The average cost of a sheathed cystoscopy compared to the standard was significantly cheaper in Lyon and almost equivalent in Marseille. CONCLUSION: The FCSDS allows significant saving over the disinfection duration, consumable costs and staff costs, while ensuring patient bacteriologic safety similar to SFC.

De novo kidney graft tumors: results from a multicentric retrospective national study.

De novo tumors in renal allografts are rare and their prevalence is underestimated. We therefore analyzed renal cell carcinomas arising in renal allografts through a retrospective French renal transplant cohort. We performed a retrospective, multicentric survey by sending questionnaires to all French kidney transplantation centers. All graft tumors diagnosed after transplantation were considered as de novo tumors. Thirty-two centers participated in this study. Seventy-nine tumors were identified among 41 806 recipients (Incidence 0.19%). Patients were 54 men and 25 women with a mean age of 47 years old at the time of diagnosis. Mean tumor size was 27.8 mm. Seventy-four (93.6%), 53 (67%) and 44 tumors (55.6%) were organ confined (T1-2), low grade (G1-2) and papillary carcinomas, respectively. Four patients died of renal cell carcinomas (5%). The mean time lapse between transplantation and RCC diagnosis was 131.7 months. Thirty-five patients underwent conservative surgery by partial nephrectomy (n = 35, 44.3%) or radiofrequency (n = 5; 6.3%). The estimated 5 years cancer specific survival rate was 94%. Most of these tumors were small and incidental. Most tumors were papillary carcinoma, low stage and low grade carcinomas. Conservative treatment has been preferred each time it was feasible in order to avoid a return to dialysis.

[Surgical management of benign prostatic hyperplasia by endoscopic techniques using electricity and open prostatectomy: A review of the literature by the LUTS committee of the French Urological Association]. / Traitement de l'hyperplasie bénigne de prostate par techniques endoscopiques électriques et adénomectomie voie haute : revue de littérature du CTMH de l'AFU.

PURPOSE: To perform an update on the surgical treatment of benign prostatic hyperplasia (BPH) by endoscopic electric resection and vaporization, and by open prostatectomy. METHOD: A systematic review of recent literature was performed. The level of evidence of each report was evaluated, and only recent publications of high level of evidence were included. RESULTS AND CONCLUSIONS: Both monopolar transurethral resection of the prostate (TURP) and open prostatectomy remain the gold standards. Endoscopic electric alternatives are monopolar and bipolar prostate vaporisation as well as bipolar resection. These techniques seem to show similar functional results than TURP and open prostatectomy, as well as an advantage in terms of bleeding.

[Surgical management of BPH by laser therapies: A review of the literature by the LUTS committee of the French urological association]. / Traitement chirurgical de l'hyperplasie bénigne de la prostate par laser : revue de littérature du CTMH de l'AFU.

PURPOSE: To perform an update on the surgical treatment of benign prostatic hyperplasia (BPH) by laser. METHOD: A systematic review of recent literature was performed. The level of evidence of each report was evaluated, and only recent publications of high level of evidence were included. RESULTS AND CONCLUSIONS: Monopolar transurethral resection of the prostate (TURP) and open prostatectomy remain the gold standards. Alternative endoscopic options are laser photoselective vaporisation, holmium enucleation and thulium resection. These techniques seem to show functional results similar to those obtained after TURP and open prostatectomy, as well as an advantage in terms of bleeding.

[Surgical management of benign prostatic hyperplasia by thermotherapy and other emerging techniques: A review of the literature by the LUTS committee of the French Urological Association]. / Traitement chirurgical de l'hyperplasie bénigne de la prostate par thermothérapie et autres techniques émergentes : revue de littérature du CTMH de l'AFU.

PURPOSE: To perform an update on mini-invasive surgical treatment of benign prostatic hyperplasia (BPH) by thermotherapy and other emerging techniques. METHOD: A systematic review of literature was performed in Pubmed database for the period running from 1980 to 2011. The level of evidence of each report was evaluated, and only recent publications of high level of evidence were included. RESULTS AND CONCLUSIONS: Monopolar transurethral resection of the prostate (TURP) and open prostatectomy remain the gold standards. Thermotherapy using transurethral microwaves or needle ablation is an alternative to medical management. Urethral stents should only be proposed in exceptional cases of surgical contra-indication, because of their related complications. Botulinium toxin and ethanol intra-prostatic injections are currently under evaluation.

[Initial assessment, follow-up and treatment of lower urinary tract symptoms related to benign prostatic hyperplasia: guidelines of the LUTS committee of the French Urological Association]. / Bilan initial, suivi et traitement des troubles mictionnels en rapport avec hyperplasie bénigne de prostate : recommandations du CTMH de l'AFU.

AIM: To elaborate guidelines for the diagnosis, the follow-up, and the treatment of benign prostatic hyperplasia (BPH). METHOD: A systematic review of the literature was conducted to select more relevant publications. The level of evidence was evaluated. Graded recommendations were written by a working group, and then reviewed by a reviewer group according to the formalized consensus technique. RESULTS: Terminology of the International Continence Society was used. Initial assessment has several aims: making sure that lower urinary tract symptoms (LUTS) are related to BPH, assessing bother related to LUTS and checking for a possible complicated bladder outlet obstruction (BOO). Initial assessment should include: medical history, LUTS assessment using a symptomatic score, physical examination including digital rectal examination, urinalysis, flow rate recording, and residual urine volume. Frequency volume chart is recommended when storage symptoms are predominant. Serum PSA should be done when the diagnosis of prostate cancer can modify the management. When a surgical treatment is discussed, serum PSA, serum creatinine and ultrasonography of the urinary tract are recommended. BPH patients should be informed of the benign and possibly progressive patterns of the disease. When LUTS cause no bother, annual follow-up should be planned. Medical treatment includes some phytotherapy agents, alpha-blockers and 5-alpha reductase inhibitors. The last two can be associated. The association of antimuscarinics and alpha-blockers can be offered to patients with residual storage symptoms when already under alpha-blockers therapy, after checking for the absence of severe BOO (residual volume more than 200mL or max urinary flow less than 10mL/s). Phosphodiesterase-5 inhibitors could be used in patients complaining for both LUTS and erectile dysfunction. In case of complication, or when medical treatment is inefficient or not tolerated, then a surgical treatment should be discussed. Treatment decision should be done according to type of LUTS and related bother, prostate anatomy, level of obstruction and its consequences on urinary tract, patient co-morbidities, experience of practitioner, and choice of patient. Surgical treatments with the higher level of evidence of efficacy include monopolar or bipolar transurethral resection of the prostate, open prostatectomy, transurethral incision of the prostate, photoselective vaporization of the prostate, and Holmium laser enuclation of the prostate. CONCLUSION: Here are the first guidelines of the French Urological Association for the initial assessment, the follow-up and the treatment of urinary disorders related to BPH.

[Initial assessment and follow-up of benign prostatic hyperplasia: systematic review of the literature by the LUTS committee of the French Urological Association]. / Bilan initial et suivi de l'hyperplasie bénigne de prostate: revue de littérature du CTMH de l'AFU.

PURPOSE: To perform an update on the initial evaluation and follow-up of benign prostatic hyperplasia (BPH). METHOD: A systematic review of recent literature was performed. Level of evidence of publications was evaluated. RESULTS AND CONCLUSIONS: Objectives of the initial evaluation are to assess the link between low urinary tract symptoms (LUTS) and BPH, to evaluate the bother associated to LUTS, assess a complicated bladder outlet obstruction (BOO), diagnose an adenocarcinoma of the prostate if it modifies the therapeutic strategy, and establish an evolutive profile of the disease. Clinical assessment with digital rectal examination, evaluation of symptoms by a dedicated questionnaire and urine analysis are the first steps of BPH evaluation. Bladder diary is useful to objective storage symptoms. Uroflowmetry and post-void residual volume assessment are useful if BOO is suspected. Measure of serum creatinine and ultrasound exam of the urinary tract are second line explorations. Urine cytology, neurological evaluation, urethrocystoscopy, urodynamics with pressure-flow studies are useful if the link between LUTS and BPH is unclear. PSA dosage is used for prostate cancer screening or as a prognostic marker of BPH evolution.

[Benign prostatic hyperplasia medical treatment: systematic review of the literature by the CTMH/AFU]. / Traitement médical de l'hyperplasie bénigne de la prostate: revue de littérature par le CTMH/AFU.

INTRODUCTION AND OBJECTIVES: The medical treatment of lower urinary tract symptoms related to benign prostatic hyperplasia (LUTS-BPH) has dramatically evolved within the last years: new drugs have been commercialized and others that used to be contra-indicated may now be prescribed. Our objective was to provide with an updated review of the scientific literature on the medical treatment of LUTS-BPH. PATIENT AND METHOD: A systematic review of the most recent scientific literature was performed. The query was addressed to the PubMed database using the following keywords: "benign prostatic hyperplasia" and "medical treatment". A very large amount of publications, from year 1990 until 2011, were reviewed to select the publications with level of evidence 1 and 2. These publications were analysed and the 30 most relevant were selected to serve as references for this article. RESULTS: There are many randomized clinical trials in the field of LUTS-BPH medical treatment. Recently, anti-muscarinic agents have been assessed and have proven their efficacy and tolerance as long as the storage symptoms are predominant over the voiding symptoms. Combination therapies using alpha-blockers and 5-alpha reductase (5-ARI) inhibitors, but also anti-muscarinic agents and PDEF-5 inhibitors may also be prescribed depending on the patient' complaint. CONCLUSION: The publication of recent randomized clinical trials allows the urologists to use new drugs and new combination therapies in the medical treatment of LUTS-BPH. In 2011, the medical treatment decision-making may better integrate the patient' complaint and medical history.

[A survey from the French Urology Association about sick leave prescriptions by 145 surgeons]. / Enquête de l'Association française d'urologie sur les pratiques de prescriptions d'arrêt de travail auprès de 145 chirurgiens urologues.

OBJECTIVES: To describe and evaluate prescriptions of sick leave by urology surgeons for different kinds of interventions. METHODS: Between January and April 2006, a web-based survey was completed by urology surgeons on a voluntary basis. The analyzed data pertained to personal characteristics of the surgeons, mean duration of sick leave for 15 interventions and the type of job of the patient (strenuous or not). Analyses were performed with software SAS™ version 9.2. Descriptive analyses were performed and Kruskal-Wallis test was used to search for statistically significant differences between variables (p<0,05). RESULTS: One hundred and forty-eight surgeons were involved and 145 answers could be analyzed. Mean age of the surgeons was 46,3±9,4years. Urology surgeons were in the public sector (n=73/140; 52%), in private practice (n=43/140; 31%) or both (n=24/140; 17%). Kruskal-Wallis test showed that all patients who had a job considered as strenuous had significantly longer sick leave prescriptions. Younger surgeons (under 40) used to prescribe shorter sick leaves than their older counterparts. CONCLUSION: Sick leave prescriptions of the urology surgeons were globally homogeneous in this survey. Only a few interventions were the occasion of discordant prescriptions depending upon the age or practice (public/private) of the surgeons. Several hypotheses could be further explored as regard the source of variation in sick leave prescriptions. These results are usable for those stakeholders who are interested in continuous medical education and evaluation.
