2022 Recommendations of the AFU Lithiasis Committee: Laser - utilization and settings.

Endocorporeal lithotripsy has progressed thanks to the development of lasers. Two laser sources are currently available: Holmium:YAG (Ho:YAG) and more recently Thulium Fiber Laser (TFL). The settings generally used are dusting, fragmentation, and "pop-corning". These are the first recommendations on laser use for stone management and their settings. Settings must be modulated and can be changed during the treatment according to the expected and obtained effects, the location and stone type that is treated. METHODOLOGY: These recommendations have been developed using two methods: the Clinical Practice Recommendation (CPR) method and the ADAPTE method, depending on whether or not the question was considered in the European Association of Urology (EAU) recommendations (https://uroweb.org/guidelines/urolithiasis [EAU Guidelines on urolithiasis. 2022]) and their adaptability to the French context.

[Urethro-vesical anastomosis reconstruction using extra-peritoneal robot-assisted laparoscopy for anastomotic stenosis after radical prostatectomy]. / Réfection d'anastomose urétro-vésicale par voie extra-péritonéale laparoscopique robot-assistée pour sténose anastomotique post-prostatectomie radicale.

INTRODUCTION: Urethro-vesical anastomosis stenosis following radical prostatectomy is a rare complication but represents a challenging situation. While the first-line treatment is endoscopic, recurrences after urethrotomies require a radical approach. We present the updated results of our patient's cohort treated by pure robotic anastomosis refection. MATERIAL AND METHODS: This is a retrospective, single-center study focusing on one surgeon's experience. Patients presented an urethro-vesical stricture following a radical prostatectomy. Each patient received at least one endoscopic treatment. The procedure consisted of a circumferential resection of the stenosis, followed by a re-anastomosis with well-vascularized tissue. We reviewed the outcomes in terms of symptomatic recurrences and continence after the reconstructive surgery. RESULTS: From April 2013 to May 2020, 8 patients underwent this procedure. Half of the patients had previously been treated with salvage radio-hormonotherapy. The median age was 70 years (64-76). The mean operative time was 109minutes (60-180) and blood loss was 120cc (50-250). One patient had an early postoperative complication, with vesico-pubic fistula. The average length of stay was 4.6 days (3-8). Mean follow-up was 24.25 months (1-66). Half of the patients experienced a recurrence at a median time of 8.25 months (6-11) after surgery. Five patients experienced incontinence of which 3 required an artificial urinary sphincter implantation. CONCLUSION: Extra-peritoneal robot-assisted urethro-vesical reconstruction is feasible and safe to manage bladder neck stricture after radical prostatectomy. The risk of postoperative incontinence is high, justifying preoperative information. LEVEL OF EVIDENCE: III.

[Recommendations of the Urolithiasis Committee of the French Urology Association for the management and the treatment of the stone formers patients during the COVID-19 pandemic crisis]. / Recommandations du Comité Lithiase de l'Association Française d'Urologie pour la prise en charge des calculs urinaires durant la crise sanitaire liée à la pandémie à COVID-19.

For the first time, faced with a crisis with an exceptional magnitude due to the COVID-19 pandemic responsible for saturation of emergency services and intensive care units, the urolithiasis committee of the French Urology Association designed the recommendations for care and treatment of stone-forming patients and their treatment during crisis.

[Evaluation of single kidney graft outcome in patients initially programmed for a dual kidney graft transplantation]. / Évaluation de greffons de bigreffe transplantés en monogreffe.

INTRODUCTION: Kidney transplantation is championed as the gold standard treatment for patients with end-stage kidney disease. According to the biomedical agency, there is an increasing number of patients waiting for kidney transplantation. Faced with organ shortage, the use of marginal grafts may well increase the number of available kidney grafts. Occasionally, during dual kidney graft transplantation, the poor quality of one of the two grafts, or other specific circumstances, may lead to transplantation of only one of the two grafts. We have compared patient outcome concerning single kidney transplantation from an initial dual kidney graft with respect to dual kidney graft transplantation. MATERIAL: Among 67 patients enrolled for a dual kidney graft, 39 dual kidney grafts (group 1) were compared with 12 grafts performed with only one of the two kidneys of a dual kidney graft (group 2) as well as 15 grafts performed following a classic kidney graft protocol (group 3). RESULTS: The survival of grafts was respectively for groups 1, 2 and 3 of 100%, 72,5% and 75,4% (P=0.17). The survival of patients was respectively for groups 1, 2 and 3 of 78.3%, 89.9% and 87.8% (P=0.47). CONCLUSION: Our study suggests that transplantation of a single kidney, initially proposed as dual kidney graft candidate, has satisfying results in terms of graft survival and patient mortality at the expense of poorer renal function in comparison to dual kidney graft. Indeed, there was no significant difference in the survival of patients and grafts. This seems promising taking into consideration that the aim of transplantation in elderly recipients is primarily to avoid dialysis, rather than having optimal post-transplantation kidney function.

[First-line screening guidelines for renal stone disease patients: a CLAFU update]. / Bilan métabolique et prise en charge médicale de la lithiase: une mise au point du CLAFU.

This text summarizes the CLAFU first-line screening guidelines for renal stone disease patients. We have focused on the useful information provided by renal stone analysis and also the identification of relevant stone risk factors detected in a 24-hour urine collection. Indeed, evaluation of water, sodium and protein intake may be easily achieved in a current clinical setting and allows a useful pedagogic tool for patients' advices and follow-up: daily diuresis above 2000 mL, calcium intake between 800 mg and 1 g/day, a moderate daily sodium and proteins restricted diet (<9 g and <1.2 g/kg per day respectively). General therapeutical principles are reviewed, including circumstances requiring specialized management.

[Update for the management of kidney stones in 2013. Lithiasis Committee of the French Association of Urology]. / Mise au point sur la prise en charge des calculs du rein en 2013. Comité Lithiase de l'Association française d'urologie.

Since the publication of the latest recommendations of the Lithiasis Comity of the French Association of Urology (CLAFU) on the management of ureteral and renal stones, practices have evolved. This text provides an update for the treatment of kidney stones. It is especially the important advances in the field of laser-ureterorenoscopy that changed practices. Percutaneous nephrolithotomy has been enriched by technical modifications and extracorporeal shockwave lithotripsy confirmed its predominant place in the first line of treatment. For stones less than 20mm, extracorporeal lithotripsy remains the standard, but in some cases the possibility of recommending a flexible ureterorenoscopy is possible in first line. For stones more than 20mm, percutaneous nephrolithotomy is the standard treatment, but optional flexible ureteroscopy and extracorporeal lithotripsy are possible. The treatment carried out, collect the stone fragments for a morpho-constitutional analysis and achieve a metabolic evaluation is necessary, to investigate etiologic and give dietary advices to prevent recurrence.

[Prognostic impact of tumors localized at the prostatic apex]. / Impact pronostique des tumeurs localisées à l'apex prostatique.

OBJECTIVE: The apex is a particular region of the prostate in its surgical dissection and pathological analysis. We sought to evaluate the prognostic value of the apical localization of prostate tumors. METHOD: From 1988 to 2010, data pre- (age, clinical stage, preoperative PSA, biopsy Gleason score) and postoperative (prostate weight, pathologic stage TNM 2010, Gleason score, margin status) of 2765 total prostatectomies were collected prospectively. These data were compared according to existence or absence of tumor at the apex. The prognostic impact of tumor at the apex on biochemical recurrence-free survival (PSA>0.2 ng/mL) has been studied in univariate and multivariate models. RESULTS: One thousand eight hundred seventeen tumors had a location at the apex (65.7%). In univariate analysis, there was a significant difference in the clinical stage, the biopsy and pathological Gleason score, the result of curage, the pathological stage and the margin status between apical tumors and others. With a mean decline of 34.6 months, 502 patients had a biochemical recurrence (18.1%). Disease-free survival at 10 years was 60.7% for tumor at the apex versus 65.9% in other cases. The location at the apex was significantly associated with biochemical recurrence on univariate analysis (P=0.01). After adjustment for clinical and pathological stage, PSA level, Gleason score and surgical margins, the apex was not anymore a pejorative independent predictor (P=0.0087). CONCLUSION: The existence of tumor in the prostatic apex was associated with more aggressive tumoral criteria and was an independent and pejorative predictor of biochemical recurrence-free survival at 10 years in univariate analysis. The apical localization could be an additional argument in the decision of adjuvant therapy after prostatectomy.

[Place of the flexible ureterorenoscopy first choice for the treatment of kidney stones. Survey results practice committee of the AFU lithiasis completed in 2011]. / Place de l'urétérorénoscopie souple en première intention pour le traitement des calculs du rein. Résultats de l'enquête de pratique du comité lithiase de l'AFU réalisée en 2011.

UNLABELLED: The flexible ureterorenoscopy coupled with photovaporisation LASER (USSR-L) for the treatment of kidney kidney is a modern tool whose place is under evaluation. METHODS: Its place has been assessed in France in 2010 by the Committee of urolithiasis of the French Association of Urology (CLAFU). A practice survey among 27 experts concerned the following decision criteria: comorbid patient's supposed nature of the calculation, anatomy of the urinary tract of the patient. This investigation has been proposed to calculate the size not exceeding 20mm, for a calculation of size greater than 20mm and for multiple calculations kidney. RESULTS: Fourteen experts responded. The criteria for the USSR-The first line were: morbid obesity (BMI>30), anticoagulation or anti platelet aggregation, calculations Hard (UH>1000, cystine stones), calculations within diverticular caliceal calculations below, the failure of a first treatment or the wish of the patient. CONCLUSION: The URS-SL was a first-line treatment validated regardless of size and number of kidney stones, when ESWL and PCNL were contraindicated or when their predictable results were poor (hard stones/morbid obesity/lower pole stones) or when stone access is difficult (intradiverticular). It was also the treatment of choice after the failure of a first treatment (ESWL/PCNL).

[Management of adult's renal and ureteral stones. Update of the Lithiasis Committee of the French Association of Urology (CLAFU). General considerations]. / Prise en charge urologique des calculs rénaux et urétéraux de l'adulte. Mise au point du Comité Lithiase de l'Association Française d'Urologie (CLAFU). Aspects généraux.

The Lithiasis Committee of the French Association of Urology (CLAFU) aimed to update the current knowledge about urolithiasis. This update will be divided into four parts: 1) general considerations; 2) the management of ureteral stones; 3) the management of kidney stones; 4) metabolic assessment and medical treatment of urolithiasis. Recent technicals advances helped the urologists to improve stones management: new extracorporeal shockwave lithotripsy (ESWL) devices, new flexible ureterorenoscopes, development of laser fragmentation. ESWL, semi-rigid and flexible ureteroscopy and the percutaneous nephrolithotomy (PCNL) remain currently the main therapeutic options. The first part of this update deals with the description and classification of stones, preoperative assessment, post-operative management and clinical follow-up. Main criteria of therapeutic choices are stone location, stone composition and stone size. Stone composition is assessed with infrared spectrophotometry analysis and its hardness is correlated with U.H. density on CT scan assessment. Preoperative assessment consists in urinary cytobacteriological examine, urinary PH, blood creatininemia, hemostasis. Low-dose CT scan is recommended before urological treatment. The result of the treatment must be done 1 or 3 months later with plain abdominal film and ultrasonography. Medical management of urolithiasis will be based on stone composition, metabolic and nutritional evaluation. Treatment success is definited by absence of residual fragments. Annual follow-up is recommended and based either on plain abdominal film and ultrasonography or low-dose CT scan.

[Pathological findings after radical prostatectomy in men eligible for active surveillance (French trial SURACAP): is the misclassification rate acceptable?]. / Surveillance active du cancer de prostate ayant des critères de latence: les critères SURACAP sont-ils suffisants?

OBJECTIVE: To analyze pathological data of the radical prostatectomy specimen in patients operated for clinically-localized prostate cancer and who meet strict criteria for active surveillance necessary to be included in the French trial SURACAP. PATIENTS AND METHODS: The data of patients who underwent a radical prostatectomy at our institution between 1998 and 2010 were reviewed. We only included the patients that met the usual criteria for active surveillance: clinical stage T1-2a tumor, PSA ≤ 10 ng/mL, biopsy Gleason sum inferior or equal to 6 with no pattern of grade 4 or 5, cancer involvement inferior or equal to two biopsy cores, inferior to 3 mm of malignant tissue in each positive biopsy core. From them, only those who were diagnosed from a second line biopsies cores were included for further analysis. RESULTS: Overall, 48 patient who met the "SURACAP" criteria had a laparoscopic radical prostatectomy at out institution. Mean age was 65.4 years. The mean preoperative PSA was 6.1 ng/mL. Clinical stage of the tumor was T1c in 95% of patients and T2a in 5%. Biopsy Gleason score was 6 (3+3) in 100%. Pathological analysis of the surgical specimen showed that 19% of patients had a seminal vesicle invasion or an extracapsular extension. The Gleason score of the pathological specimen was 6 (3+3) in 57% of patients, 7 (3+4) in 38% and 8 (4+4) in 5% of patients. The Gleason score upgrading was 43% of patients. CONCLUSION: In our experience, 19% of patients who meet the criteria for active surveillance show an extracapsular extension or a seminal vesicle invasion on pathological analysis. Active surveillance is still under evaluation.

[Laparoscopic radical prostatectomy in the elderly (>75 years old): oncological and functional results]. / Prostatectomie radicale laparoscopique chez la personne âgée (>75ans): résultats carcinologiques et fonctionnels.

OBJECTIVE: Prostate cancer incidence increases with age. Radical prostatectomy (RP) seems to be feasible for elderly well-selected patients. We report our experience with patients older than 75 years old who underwent laparoscopic RP. METHODS: From 2000 to 2007, 22 patients older than 75 years old at time of surgery were included in the study. The patient clinical characteristics, the peri- and postoperative data, and the pathological data were collected retrospectively. The overall, specific and PSA-free survival were analysed with Kaplan-Meier method. The functional results such as continence and erectile function were assessed by self-questionnaires. RESULTS: The mean patient age was 75 years (75-81), the median PSA level was 10.77 ng/ml (5-30). The mean American Society of Anesthesiologists score was 2.1 (2-3). Two (9%) perioperative complications occurred but no conversion was necessary. Five patients (23%) had a pT3 disease and the overall positive surgical margins rate was 14%. With a median follow-up of 42 months, no patient has died and five had a biochemical recurrence. At 12-month follow-up, 82% of patients were continent (no pad) and potency (erection sufficient for intercourse) rate was 36% with or without the use of phosphodiesterase-5 inhibitors. CONCLUSION: Laparoscopic RP is feasible for localized prostate cancer in elderly well-selected patients with satisfactory oncological and functional outcomes although the incontinence rate is increased comparing to younger patients.

[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.
