[Partial versus radical nephrectomy for renal cell carcinoma involving peri renal fat. Oncological and functional outcomes]. / Néphrectomie partielle versus élargie en cas d'envahissement de la graisse périrénale. Résultats oncologiques et fonctionnels.

PURPOSE: In the latest guidelines of the European Association of Urology, partial nephrectomy was a reference standard in tumors less than 7cm confined to the kidney. The invasion of the perirenal fat and therefore dissection in a potentially tumor tissue with an increased risk of recurrence. MATERIAL: From 1995 to 2009, we retrospectively evaluated the oncological outcomes of partial versus radical nephrectomy in tumors with local extension beyond the boundaries of the kidney, without adrenal involvement or metastatic lymph node extension. We evaluated the histological factors influencing the prognostic. RESULTS: A total of 43patients have been included (ten partial and 33radical nephrectomy). We did not found any significant difference in terms of specific and recurrence-free survival between partial and radical nephrectomy in tumor invading the perirenal fat (P=0.739 and P=0.683 respectively). Factors influencing the prognosis were the Fuhrman grade (P=0.010), the invasion of the urinary tract (P=0.017) and the presence of a positive surgical margin (P=0.041). The renal function was better after partial nephrectomy. The complication rate was similar between partial and radical nephrectomy. CONCLUSION: The perirenal fat invasion by kidney tumor did not impact the oncological outcomes of partial versus radical nephrectomy with better functional outcomes for partial nephrectomy.

[Outcomes of HIFU for localised prostate cancer using the Ablatherm Integrate Imaging® device]. / Traitement du cancer localisé de la prostate avec l'appareil Ablatherm Imagerie Intégrée® : résultats carcinologiques et fonctionnels.

OBJECTIVES: To report the functional and oncological outcomes of HIFU for prostate cancer using the Ablatherm Integrate Imaging(®) device. METHODS: Between January 2005 and June 2009, all patients treated with HIFU as a primary care option for localized prostate cancer and fulfilling the French Urological Association (AFU) guideline were included in this study. Validated questionnaires were used to assess continence, potencies and quality of life. RESULTS: A total of 297 patients met the inclusion criteria: 149 were low risk and 148 were intermediate risk according to d'Amico's risk group. The median prostate specific antigen (PSA) nadir was 0.12ng/ml with 65% of patients reaching a nadir less than 0.3 ng/ml. Systematic control biopsies were performed on 175 patients with 89% of negative biopsies. The disease free survival rate at 40 months was 79% for low risk group and 62% for intermediate risk group. The pre and post-HIFU treatment International Prostate Symptoms Score (IPSS) score and quality of life questionnaire were not statistically different. In the opposite, the pre and post-HIFU erection function and continence status were significantly different. CONCLUSION: Local control and Biochemical Free Survival Rate achieved with HIFU were similar to those expected with conformal external radiation beam therapy. Among the functional outcomes, potency was the most impacted by the treatment.

[Progress and summary of recent congress: ASCO-GU, EAU, AUA, ASCO about the medical management of locally advanced or metastatic kidney cancer]. / Avancées et synthèse des derniers congrès: ASCO-GU, EAU, AUA, ASCO concernant la prise en charge médicale du cancer du rein localement avancé ou métastatique.

During the recent congress of urology and oncology key topics discussed were the evolution of survival data in metastatic kidney cancer which median is now around 40 months, persistent questions about the role of nephrectomy, including access to the systemic treatment of nephrectomized patients and tumor resectability induced by systemic therapies, the emergence of new prognostic models which are adapted to new therapeutic standards, and the emergence of promising new drugs including pazopanib. This article describes these advances.

[Clamping modalities during partial nephrectomy: technical aspects and functional consequences. Review by the Comité de cancérologie de l'Association française d'urologie (CCAFU)]. / Modalités de clampage au cours de la néphrectomie partielle: aspects techniques et conséquences fonctionnelles. Revue du sous-comité rein du Comité de cancérologie de l'Association française d'urologie (CCAFU).

Partial nephrectomy requires control of renal blood flow by using renal vessels clamping. Multiple clamping techniques are available. The clamping procedure can be parenchymal or vascular, involving enbloc arterial and veinous clamping or arterial onlone, being continuous or intermittent, associated or not with renal cooling. The purpose of this present review was to analyze technical aspects of clamping methods during partial nephrectomy and their functional consequences in terms of blood loss, surgical margins status and changes in renal function.

[Urinary incontinence due to chronic cough in interstitial lung disease]. / Incontinence urinaire à la toux au cours des pneumopathies interstitielles diffuses.

INTRODUCTION: Urinary stress incontinence affects 10% to 30% of the female population and may have a major impact on psychosocial health. In interstitial lung disease, chronic cough may lead to development of urinary incontinence, but the prevalence and impact of this symptom are unknown. OBJECTIVES: To determine the rate and impact of urinary stress incontinence among women with chronic cough due to interstitial lung disease. METHODS: 28 female patients with chronic cough secondary to interstitial lung disease and 15 controls were evaluated by questionnaires to determine the prevalence of cough-related urinary incontinence, its severity, and its impact on quality of life. RESULTS: Cough-related urinary incontinence was present in 14/28 patients with interstitial lung disease and chronic cough (50%), but in only 1/15 controls (7%, p=0.005). On a 5-points quality of life scale, the median impact of urinary incontinence was 3 (minimum=1, maximal=5), and the median impact of chronic cough was 3.5. The majority of patients (64%) believed that incontinence was a natural phenomenon due to ageing, all were ashamed by this symptom and 79% were unable to mention it to their caring physician. Only one physician had previously addressed this issue. CONCLUSION: Cough-related urinary incontinence is common in patients with interstitial lung disease and is largely overlooked. It may significantly alter quality of life. A systematic questioning by the physician would allow to promptly refer these patients for appropriate therapeutic interventions, such as perineal training.

[Atypical cysts and cystic tumours of the kidney: histological, radiological and surgical considerations. Conclusions of the AFU 2007 forum]. / Kystes atypiques et tumeurs kystiques du rein : considérations anatomopathologiques, radiologiques et chirurgicales. Conclusions du forum AFU 2007.

Malignant tumours may have a cystic appearance. They are dominated by multilocular cystic renal cell carcinoma, usually low-grade, which rarely metastasize. The Bosniak classification distinguishes non suspicious lesions (type I and II) from suspicious lesions (type III and IV) requiring resection and lesions requiring follow-up (type IIF). The main feature suggestive of malignancy is the enhancement of the septa and the walls of the cyst. Renal cysts classified as IIF require surveillance by contrast-enhanced imaging (CT, MRI or ultrasound). The treatment of cystic tumours is based on surgery. Partial nephrectomy is recommended in this type of tumour regardless of the size. Laparoscopy is a validated technique in experienced hands. Aspiration is not very effective for the treatment of benign cysts, but may be useful for diagnosis. Surgical resection of the roof of the cyst is the most effective technique.

[Bone-anchored suburethral sling complicated by pubic osteomyelitis: a case report]. / Bandelette sous-urétrale avec ancrage osseux compliquée d'une ostéomyélite pubienne : à propos de deux cas.

The bulbo-urethral compression through a non-resorbable sling is a new therapeutic approach in the management of male stress urinary incontinence after prostatic surgery. Several slings are being evaluated and their way of fixing is variable according to the technique adopted. The InVancetrade mark process ensures bulbo-urethral compression by a synthetic sling anchored to the ischio-pubic rami through several titanium screws. We report the case of two patients whose operating suites of the InVancetrade mark bone-anchored male sling surgery have been marked by the appearance of a perineal suppuration associated with a pubic osteomyelitis. The healing was achieved after explantation of the material implanted (screws and sling) with bone debridement and prolonged antibiotics.

[The place of laparoscopic nephrectomy in the elderly subject]. / Place de la néphrectomie laparoscopique chez le sujet âgé.

The concomitant increase in life expectancy and the incidence of kidney cancers will result in an increase in kidney cancers in subjects over 75 years of age in the coming years. A wait-and-see attitude in cases of voluminous tumors, particularly symptomatic tumors, may well alter the quality of life of these patients through chronic abdominal pain, macroscopic hematuria, or alteration of the general condition due to metastatic progression. Curative or palliative surgical management can be envisioned and should be discussed in the multidisciplinary consensus meeting. Before validating the indication for nephrectomy in the elderly patient, a preoperative geriatric assessment should be made. Moreover, preoperative renal function should be carefully evaluated to measure the risk of terminal renal failure. The reduction in the mean duration of the hospital stay provided by laparoscopic surgery allows patients to return home or to their institution more quickly, an important consideration in the rehabilitation of these patients, who are very sensitive to such changes. Laparoscopic nephrectomy, with evidence in the literature of reduced morbidity and satisfactory oncological results, could therefore be superior to open surgery when indicated and technically feasible.

[Do ablative treatments modify the management of kidney tumors in the elderly?]. / Les traitements ablatifs modifient-ils la prise en charge des tumeurs du rein chez la personne âgée?

The development of ablative techniques in renal oncology has profoundly changed treatment of small renal tumors. The objective of this review of the literature was to assess the arguments for treating localized kidney tumors with these techniques in the elderly patient. The two techniques retained because of their recognized use, for all approaches, are radiofrequency and cryotherapy. The data in the literature report more frequent local recurrence with these techniques than with surgical excision and an advantage to cryotherapy over radiofrequency. There seems to be no difference in terms of metastatic progression. Morbidity is not insignificant, with major complications in slightly less than 10% of cases. Given the need to consider small tumors (<4 cm), the advantage in terms of life expectancy is challenged by series studying active monitoring of the oldest patients who present co-morbidities. At present, the indications should therefore be measured and based on a general assessment of the patient, with particular consideration of the existing co-morbidities so as not to treat a patient while imposing undue complications.

[Treatment of metastatic kidney cancer in elderly subjects]. / Traitement du cancer du rein métastatique chez les sujets âgés.

Treatment of metastatic kidney cancer in elderly subjects is identical to treatment of younger subjects. Whereas cytokines were classically contraindicated in patients over 70 or 75 years (notably IL2), new targeted therapies have been evaluated and found to be usable with no age limit, and all of the phase III studies have included patients 80 years old and older. Overall, there seems to be no difference in efficacy based on age (except perhaps for temsirolimus). As for tolerance, it is satisfactory for all therapies. Dose reduction is slightly more frequent, which calls for caution, notably with sunitinib, for which a direct correlation between the dose administered and efficacy has been reported. Given the data available today, no dose adaptation in relation to age is recommended in metastatic renal cancer.

Salvage radiotherapy after high-intensity focused ultrasound for localized prostate cancer: early clinical results.

OBJECTIVES: To evaluate the first results of salvage radiotherapy after high-intensity focused ultrasound (HIFU) in terms of feasibility, tolerance, and oncologic control. METHODS: From March 1995 to May 2004, 45 patients presenting with local failure after HIFU underwent salvage radiotherapy alone (n = 32) or combined with hormonal therapy (n = 13). The modalities of radiotherapy are described. Tolerance was evaluated using the Radiation Therapy Oncology Group score for urinary and digestive side effects, and incontinence was evaluated using the Ingelman Sundberg score. Patients answered a questionnaire. For the 32 patients who underwent radiotherapy alone, the oncologic early results were given by the disease-free survival rate, defined as no biochemical progression and no androgen suppression therapy. RESULTS: The median and mean follow-up were 40 and 46 months, respectively, for the whole series. No additional digestive or urinary toxicity developed with salvage radiotherapy after HIFU. The data from 32 patients were evaluated, with a median follow-up of 37 months after radiotherapy. The 5-year disease-free survival rate was 64% for the 32 patients evaluated. The 5-year disease-free survival rate reached 80% for patients treated for positive biopsy findings and was 44% for those with isolated biochemical failure. CONCLUSIONS: Salvage radiotherapy after HIFU for local recurrence is feasible, with no additional toxicity. The early oncologic results are encouraging when isolated local recurrence is proven but longer follow-up is needed.

[What may be the waiting time between the diagnosis and surgical treatment of kidney cancer?]. / Quelle peut être la durée du délai entre le diagnostic et le traitement chirurgical du cancer du rein?

When announcing the diagnosis of renal cell carcinoma, the urologist and the patient can wonder about the waiting time for surgically treating the cancer. This review aimed to investigate the scientific facts to determine the time between the diagnosis of kidney cancer and the achievement of surgically. The natural history of kidney cancer has been the fundamental of the therapeutic management. The time between diagnosis and surgical treatment depends on the conditions under which the diagnosis was established. Patients with symptomatic cancer or discovered at metastatic stage had to be treated quickly. In case of incidental diagnosis, evaluation of tumors has resulted in the selection of patients who can wait several months between diagnosis and surgical treatment of kidney cancer on the condition watchful waiting. The modalities of this assessment, radiological and anatomopathological, must be validated by further studies.

[Locally recurrent prostatic adenocarcinoma after exclusive radiotherapy: results of high intensity focused ultrasound]. / Adénocarcinome prostatique en récidive locale après radiothérapie exclusive: résultats du traitement par ultrasons focalisés.

OBJECTIVES: To determine the efficacy and adverse effects of high intensity focused ultrasound (HIFU) for the treatment of local recurrence of prostate cancer after exclusive external beam radiotherapy. MATERIAL AND METHODS: Seventy-two patients with histologically and biologically documented local recurrence after radiotherapy were treated by HIFU. The mean age was 68.27+/-5.93 years, and mean PSA was 6.64+/-7.26ng/ml. Thirty patients were treated according to standard parameters and 42 according to specific parameters. ASTRO 2005 criteria, specific for salvage therapy (Phoenix consensus), were used to define recurrence. Progression-free survival was calculated by the Kaplan-Meier method. RESULTS: Mean follow-up was 39+/-28 months. The negative biopsy rate was 80% and the median nadir PSA was 0.10ng/ml. Specific survival was 94% at three years and 90% at five years, and progression-free survival was 50% at three years and 44% at five years. The urinary incontinence rate was 44% (grade 1 : 12%, grade 2/3 : 32%) and the urethral stricture or bladder neck stenosis rate was 30%. The use of specific parameters reduced the incidence of severe incontinence (19% versus 50, P=0.005) and stenosis (24% versus 40). CONCLUSIONS: Treatment with HIFU achieved a five-year progression-free survival of 44%, but patients must be clearly informed about the high rate of adverse effects.

[AMS 800 artificial urinary sphincter implantation: can the penoscrotal approach constitute an alternative to the perineal approach?]. / Implantation du sphincter urinaire artificiel AMS 800: la voie péno-scrotale est-elle une alternative à la voie périnéale ?

OBJECTIVE: To compare the short-term results of penoscrotal and perineal artificial urinary sphincter implantation. PATIENTS AND METHODS: From May 2005 to February 2007, 37 artificial urinary sphincters were implanted successively, via a penoscrotal approach in 16 cases and via a perineal approach in 21 cases. Incontinence was secondary to prostate surgery (n=36) and pelvic trauma (n=1). Seventeen patients had a history of external beam radiotherapy. The times and modalities of activation of the sphincter were identical in the two groups. RESULTS: The mean age of the patients, the mean operating time, the mean catheterization duration, the mean hospital stay and the mean postoperative follow-up were equivalent in the two groups. Six urethral erosions (37.5%) and one scrotal erosion due to the pump (6.6%) were observed in the penoscrotal group and infection of the sphincter in two patients (9.5%) and pump migration in another two patients (9.5%), but no urethral erosions were observed in the perineal group. The success rate without revision was 56% in the penoscrotal group and 71.5% in the perineal group. CONCLUSION: The perineal approach is the reference incision, as the penoscrotal approach is associated with a high rate of erosion. The penoscrotal urethral approach can constitute an alternative when the bulbar urethra cannot be used.

[Indications, techniques and outcomes of high-intensity focused ultrasound (HIFU) for the treatment of localized prostate cancer]. / Indications, techniques et résultats du traitement par ultrasons focalisés (HIFU) du cancer localisé de la prostate.

High-intensity focused ultrasound (HIFU) is a minimally invasive alternative for patients with localized prostate cancer, not suitable for radical prostatectomy because of a life expectancy less than 10 years or because of major co-morbidities precluding surgery. HIFU can be performed in patients with LUTS (associated TURP) or with a previous history of BPH surgery. HIFU is repeatable after the initial procedure if a recurrent cancer is diagnosed on control biopsies. Furthermore, this therapy is a viable option for patients with a local relapse after external beam radiation therapy: oncologic efficacy is conversely related to the initial prostate cancer stage before radiation therapy.
