[Urinary tract infections in adults: Comparison of the French and the European guidelines]. / Infections urinaires de l'adulte : comparaison des recommandations françaises et européennes. Par le Comité d'infectiologie de l'Association française d'urologie (CIAFU).

INTRODUCTION: Acute urinary tract infections (UTIs) in adult are now a major public health issue in terms of morbidity, mortality and in terms of costs for society. The latest French guidelines and the European Association of Urology guidelines differ in some points. The aim of this article is to compare the guidelines of these two societies in order to highlight their differences but also their common points in the management of UTIs. METHODS: A comparative analysis of the latest French and European guidelines was carried out. The authors defined the following sub-sections: terminology, pyelonephritis, male UTIs, pregnancy urinary tract infections and cystitis. RESULTS AND CONCLUSION: The guidelines of these two societies are not very different in terms of diagnostic and therapeutic management. The major differences are in the duration of antibiotic therapies, where French guidelines continue to recommend long term treatments where EAU sometimes recommends only 5 days of antibiotics, as in the case of simple acute pyelonephritis.

Perioperative infectious risk in urology: Management of preoperative polymicrobial urine culture. A systematic review. By the infectious disease Committee of the French Association of urology.

INTRODUCTION: The aim was to assess the risk of postoperative infections in patients with preoperative polymicrobial urine culture and to provide the urologist with practices to minimise the risk of infection in these clinical situations. METHODS: A systematic literature review was carried. All national and international recommendations have been reviewed. Data collection has been performed from the Cochrane, LILACS and the Medline database. 31 publications were selected for inclusion. RESULTS: Risk of infection in patients without ureteral stents or urinary catheters with previous polymicrobial urine culture is low. In the absence of leukocyturia, the urine sample can be considered as sterile. With ureteral stents or urinary catheters, the colonisation by biofilm ranges from 4 to 100% depending on the duration and ureteral stents or urinary catheters type. Urine culture is positive 24 to 45% of the time when ureteral stents or urinary catheters are known to be colonised. The post-operative risk of infection in endo-urological surgery in a patient with ureteral stents or urinary catheters is estimated around 8 to 11% depending on the type of surgery. A retrospective study reports a postoperative infections rate of 18.5% in photo selective vaporization of the prostate with preoperative polymicrobial urine culture. CONCLUSIONS: Scientific data are limited but for patients without ureteral stents or urinary catheters, in the absence of leukocyturia, the polymicrobial urine culture can be considered as negative. Considering a preoperative polymicrobial urine culture as sterile in patients with colonised ureteral stents or urinary catheters is at risk of neglecting a high risk of postoperative infections or sepsis even in case of perioperative antibiotic prophylaxis. It should not always be considered sterile and therefore, a perioperative antibiotic therapy could be an acceptable option.

[Can the urine dipstick be used in the diagnosis of urinary bacterial colonizations in a preoperative urological assessment?]. / La bandelette urinaire peut-elle être utilisée pour le diagnostic des colonisations bactériennes urinaires dans le bilan préopératoire urologique?

PURPOSE: The use of the dipstick urinalysis has been validated for the diagnosis of symptomatic urinary infections, cystitis and pyelonephritis thanks to an excellent negative predictive value. For prostatitis, it is rather its positive predictive value that is interesting. The aim of this study is to validate its use in the screening of urinary colonizations in the preoperative assessment in urology. METHODS: A monocentric prospective study was carried out for one year in 2011 comparing the data from the urine dipstick test with a fresh-voided midstream urinary examination and culture performed on the day of admission with the same urine sample in 598 asymptomatic patients programmed for a urological procedure. The gold standard to diagnose a microbiological-confirmed urinary tract infection or colonization was uropathogen growth of ≥10(3) colony-forming units per ml (cfu/mL) with or without leucocyturia. RESULTS: The study disclosed 5% of colonized patients. The urine dipstick test had a 65% sensitivity and a 97% negative predictive value. However, the low sensitivity of the urine dipstick test entailed 34% of false negatives. CONCLUSION: In spite of a good negative predictive value linked to a low prevalence of colonized patients (5%), the low sensitivity of the urine dipstick test entails a non-negligible number of false negatives. Its use as a single test of preoperative screening would expose colonized patients to the prospect of an operation, which seems to be unacceptable for some of them, notably endoscopic ones.

[Recommendations of the Infectious Disease Committee of the French Association of Urology. Diagnosis, treatment and monitoring candiduria]. / Recommandations du comité d'infectiologie de l'AFU. Diagnostic, traitement et suivi des candiduries.

The candiduria are frequently encountered in urology. We present the recommendations of the Infectious Diseases Committee of the French Association of Urology for diagnosis, treatment and monitoring of urinary tract infections. C. albicans is the most frequently isolated species, representing 60% of the isolates. Immunosuppression, diabetes mellitus, age extremes of life, the presence of catheters or procedures on the urinary tract are risk factors for Candida urinary tract infection. The candiduria is usually asymptomatic and does not need treatment. Only 4-14% of patients with candiduria have symptoms of urinary infection. It is necessary before choosing candiduria isolated on a first urinalysis to eliminate contamination by conducting a second harvest. In patients surveyed, the removal of the material allows the resolution of the candiduria nearly half the time and represents the first step of management. Oral fluconazole is the recommended treatment for cystitis (400 mg on day 1 and 200 mg daily for 7 to 14 days). In cases of pyelonephritis without associated candidemia, the first-line therapy is fluconazole (3-6 mg/kg/day) for 14 days or amphotericin B at a dose of 0.5 to 0.7 mg/kg/day with or not associated to flucytosine when potentially resistant strain (C. glabrata).

[Diagnosis, treatment and follow-up of community-acquired bacterial infections of the urinary system of men and women (acute cystitis and acute pyelonephritis) and of the genital system of men (acute prostatitis): general remarks]. / Généralités.

Urinary tract infections are frequent. The aim of these guidelines is to improve the management of urionary tract infections. Increasing antibiotic prescriptions may increase bacterial drug resistance. Asymptomatic bacteriuria, bacterial count, pyuria are defined and the clinical value of the bacterial culture and urinary dipstick test are discussed. The good antibiotic use depends on bacteriological, pharmaceutical, patient characteristics and economic findings which are precised in these guidelines.

[Acute cystitis]. / Cystites aiguës.

The management of uncomplicated lower urinary tract infections (UTI) implicate to look for risk factors and complications. Bacterial or radiological exams are not recommanded and short course of antibiotic is effective for treating uncomplicated UTI. Complicated UTI needs clinical, bacteriological and radiological exams, longer treatments are recommanded. Recurrent UTI definition is precised in these guidelines.

[Abbé-Mustardé's flap with lower lid transposition: three clinical cases]. / Intérêt du lambeau de transposition palpébrale d'Abbé-Mustardé : à propos de trois cas cliniques.

The ideal solution first recommended is the use of Abbé-Mustardé's flap with lower lid transposition to rebuild the total loss of the upper eyelid. Every step of the surgical technique has been detailed to improve the result and keep the drawbacks under control. After having read articles on this subject, we describe three clinical cases, which enable us to compare with others surgical techniques that cannot rebuild all the levels of the eyelids and the edge of the eyelashes.

[Ethmoid adenocarcinoma: trans-facial approach for anterior skull base resection. a series of 80 cases]. / Adénocarcinomes de l'ethmoïde: expérience nantaise (80 cas).

OBJECTIVE: To present results of a retrospective analysis of eighty cases of ethmoid adenocarcinoma. Carcinologic and surgical results of anterior skull base resection via the transfacial approach are presented. METHODS: Tumors were classified as 5% T1, 23% T2, 31% T3, 21% T4a and 20% T4b. Thirty-four patients were treated via a paralateronasal approach without skull base resection. Anterior skull bas resections were performed via the transfacial approach for 26 patients and by combined neurosurgical approach for 21. RESULTS: Mean follow-up was 4.8 years. Survival rate was 63.4% at 5 years and 57.9% at 8 years. Forty-two patients were alive and disease-free at last follow-up. Three patients were alive with recurrence. The rate of local recurrence was 38.8%. Complications occurred in 20% of the patients who had a transfacial approach. Complications appeared to be less frequent than with the combined approach. CONCLUSION: Prognosis is related to local control and could be improved by using skull base resection more systematically. In our experience this can be managed by a transfacial approach with similar carcinological results and less complications than the combined approach.

[The intratesticular leiomyoma: an unusual location. Report of a case]. / Le léiomyome intratesticulaire: une localisation exceptionnelle. A propos d'un cas.

Intratesticular location of leiomyoma is unusual. A single case has been published in the literature. We report a case of what we consider to be an intratesticular leiomyoma, with a description of its pathology, a discussion of its differential diagnosis and histogenesis.

[Epidermoid carcinoma of the bladder]. / Carcinome épidermoïde de la vessie.

Squamous carcinoma of the bladder is a rare tumour, little known in Western countries in contrast with the high incidence in the Middle East and East Africa. It has a sex-ratio of 1 and black populations appear to be preferentially affected. Several recent theories of carcinogenesis elucidate the pathophysiology of this tumour. Its risk factors essentially consist of urinary schistosomiasis and mechanical and chemical vesical irritant factors. The diagnosis of this cancer is often delayed, but can be facilitated by strict follow-up of high-risk patients. Prevention appears possible in these patients. Its prognosis, traditionally poor, essentially depends on tumour stage and grade. Treatment is surgical, essentially radical cystectomy, which has a real therapeutic efficacy. The respective roles of chemotherapy and radiotherapy are currently under evaluation.

[Clinical stage T3 prostate cancer: natural history, therapeutic choices and their results]. / Cancer de prostate de stade T3 clinique: histoire naturelle, les choix thérapeutiques et leurs résultats.

Clinical stage T3 prostate cancer is ambiguous both in terms of its definition and its place in the natural history of the disease, and there is no consensus concerning its treatment. In a review of the literature, 148 articles were selected and analysed from the Medline database over a 14-year period (1983-1997). Single-agent therapy: Radiotherapy and radical prostatectomy: it is unlikely that these treatments can cure clinical stage T3 prostatic cancer, except perhaps for a small minority of patients actually presenting with overstaged pT2 disease or certain forms of low-grade pT3. Neither treatment appears to have any advantage over the other-Endocrine therapy: it has been proposed as exclusive treatment at this stage. Few studies have been reported. However, many authors consider this choice to be legitimate, because one-half of patients already have lymph node involvement. Combination therapy: Radiotherapy and endocrine therapy: recent studies comparing exclusive external beram radiotherapy with endocrine therapy show an advantage in favour of combination therapy. Total prostatectomy and endocrine therapy: neoadjuvant endocrine therapy does not provide any advantage. Adjuvant endocrine therapy improves local control and progression-free survival. Adjuvant radiotherapy and radical prostatectomy provides no advantage for T3. The choice of treatment for stage T3, N0, M0 obviously depends on the patient's general state and life expectancy. If the option of a curative treatment in a young subject can be reasonably considered, combination therapy should be preferred.

Spontaneous rupture of orthotopic detubularized ileal bladder replacement: report of 5 cases.

PURPOSE: We defined the mechanisms responsible for rupture of orthotopic, detubularized ileal bladder replacement. MATERIALS AND METHODS: We reviewed retrospectively the records of 5 cases of ileal neobladder rupture treated at our center between 1985 and 1995. RESULTS: The interval to perforation varied from 3 to 60 months after surgery. The perforation site was typically the upper part of the right limb of the reservoir. We observed an acute episode of bladder over distension immediately before perforation in 2 cases and a chronic state of neobladder over distension in the 3 remaining cases. Bacterial infection was associated in 4 cases. Intraperitoneal adhesions were an associated mechanism for rupture in only 1 case. We found chronic ischemic changes weakening the bladder wall to be an additional factor for rupture in the 3 cases associated with chronic over distension. CONCLUSIONS: Acute or chronic over distension of the neobladder is the main factor for spontaneous rupture of orthotopic detubularized ileal bladder replacement. Chronic ischemic changes of the bladder wall, possibly facilitated by detubularization and the variability of the mesenteric circulation, are additional factors that lead to perforation.

[Can the combination of bladder ultrasonography and urinary cytodiagnosis replace cystoscopy in the diagnosis and follow-up of tumors of the bladder?]. / L'association échographie vésicale-cytodiagnostic urinaire peut-elle remplacer la cystoscopie dans le diagnostic et la surveillance des tumeurs de vessie?

OBJECTIVES: Cystoscopy is currently the reference examination for the diagnosis and surveillance of bladder tumours (BT). However, this examination remains unpleasant for the patient, despite the development of flexible cystoscopes. Among the many diagnostic methods performed in combination with cystoscopy, the authors decided to evaluate the performances of the combination of ultrasonography+urine cytology in the diagnosis and follow-up of bladder tumours. METHODS: This prospective study included 124 cases in the context of postoperative surveillance of BT (86) or aetiological assessment of haematuria (38). All patients were assessed by cystoscopy, suprapubic vesical ultrasonography, and urine cytology. RESULT: Cystoscopy revealed a bladder tumour in 30 patients. Urine cytology had a sensitivity of 53% and a negative predictive value (NPV) of 86%. Vesical ultrasonography had a sensitivity of 50% and an NPV of 85%. The false-positive and false-negative results of ultrasonography and urine cytology make these examinations unreliable when considered separately. The combination of ultrasonography and urine cytology had an overall sensitivity of 80% and an NPV of 93%. However, analysis of the group of patients undergoing postoperative surveillance for BT showed that although the combination of the two examinations had a diagnostic sensitivity of 100% in the case of high-grade tumour or CIS, this value was only 66% for low-grade tumours. The authors review other methods of bladder tumour diagnosis, but none of them appears to have demonstrated a sufficient reliability at the present time. CONCLUSION: The diagnostic sensitivity of the combination of ultrasonography and urine cytology, accurate but not recommended in high-risk patients with a high-grade BT, does not appear to be sufficient for systematic surveillance of patients with low-grade BT, despite the low risk of recurrence.

[Hemostasis technics in partial nephrectomy]. / Technique d'hémostase dans la néphrectomie partielle.

The authors describe an original haemostasis technique during partial nephrectomy, combining provisional pressure haemostasis of the renal parenchyma using atraumatic vascular clamps, and application of haemostatic sutures on a strip of Gore-Tex Reinforcement Tissue. This technique, which has been used three times, appears to be simple, facilitates exposure of the renal section, and ensures effective haemostasis. It does not require control or clamping of the pedicle or local hypothermia. No postoperative complication (urinary fistula, secondary haemorrhage, Gore Tex infection) was observed.

Plasma neuroendocrine markers in patients with benign prostatic hyperplasia and prostatic carcinoma.

PURPOSE: Approximately 50% of all malignant prostatic tumors contain neuroendocrine cells, which cannot be attributed to small cell prostatic carcinoma or carcinoid-like tumors, and which represent only 1 to 2% of all prostatic malignancies. Only limited data are available concerning the plasma levels of neuroendocrine markers in patients with prostatic tumors. Therefore, we determine the incidence of high plasma levels of neuroendocrine markers in patients with benign and malignant prostatic disease. MATERIALS AND METHODS: The presence of elevated plasma neuropeptide levels was investigated in 135 patients with prostatic carcinoma and 28 with benign prostatic hyperplasia. Plasma chromogranin A, neurone-specific enolase, substance P, calcitonin, somatostatin, neurotensin and bombesin levels were analyzed by immunoassays, and were compared to clinical and pathological stages of disease. Plasma prostatic acid phosphatase and prostate specific antigen levels were also determined. All patients were followed for at least 2 years after inclusion in the study. RESULTS: Significantly elevated levels of chromogranin A were detected in 15% of patients with prostatic carcinoma before any treatment. During hormone resistant prostate cancer progression plasma chromogranin A and neuron-specific enolase levels were elevated in 55% and 30% of the patients, respectively. In patients with stage D3 disease survival curves were generated by the Kaplan-Meier method, and log rank analysis revealed a statistically significant difference between groups positive and negative for chromogranin A. Substance P and bombesin were also occasionally elevated in prostatic tumors. Determination of neuroendocrine differentiation by neuron-specific enolase or chromogranin A immunoassays was not helpful in the prediction of progressive localized prostatic carcinoma. CONCLUSIONS: Future studies of plasma neuropeptide levels should confirm whether these parameters can be used as prognostic markers during late progression of prostatic carcinoma or for the selection of patients suitable for evaluation of new antineoplastic drugs to be active against neuroendocrine tumors.

[Embryonal carcinoma and anaplastic seminoma of the testis: diagnostic difficulties]. / Carcinome embryonnaire et séminome anaplasique du testicule: difficultés diagnostiques.

In this case report concerning a testicular tumor, the difficulty of discriminating between embryonic carcinoma with granulomatous reaction and anaplastic seminoma is described. According to the literature and the findings of the present case, the value of immunohistochemical investigations is emphasized, especially the use of anti cytokeratin antibody in the diagnosis of embryonic carcinoma. Therapeutic issues stress the importance of such a diagnosis. Furthermore the immunohistochemical identification of embryonic carcinoma in every case should lead to a new classification of the so-called anaplastic seminoma's entity.
