One-year Functional Outcomes after Holmium Laser Enucleation of the Prostate (HoLEP): Introduction of a Composite Score (Hexafecta).

OBJECTIVE: To compare the efficiency (micturition symptoms, continence, erection) and safety of Holmium Laser Enucleation of the Prostate (HoLEP) with a single composite score (the Hexafecta score) one year postprocedure. PATIENTS AND METHODS: We conducted a single-center retrospective study including all patients who had undergone HoLEP for the treatment of benign prostate hyperplasia (BPH) between May 2013 and August 2017. Data were obtained preoperatively and at the 6- and 12-month visits. We also reported all 90-day complications. The Hexafecta score included 6 criteria: peak urine flow of at least 15ml/s, 30% reduction in International Prostate Symptoms Score (IPSS) score, quality of life via the IPSS less than 2, no incontinence (International Consultation Incontinence Questionnaire), no significant change in erectile function (International Index of Erectile Function), and no grade III or more complications according to the Clavien-Dindo classification. RESULTS: Two hundred thirty-five patients were included, of whom 197 (83.8%) completed the 12-month visit. Complete data were available to assess the Hexafecta score for 178 of them (75.7%). Most of the missing data were for uroflowmetry and the erectile function assessment. Hundred three patients (58%) met all 6 criteria, while 45 (25%) met 5 of them. None were retreated for BPH in the follow-up period. The de novo incontinence rate was 4.1%. CONCLUSION: The Hexafecta score is a simple, transversal method for comprehensively evaluating functional outcomes after HoLEP surgery. Such an evaluation could be used to compare other types of procedures for BPH treatment. LEVEL OF EVIDENCE: 3.

[Anticoagulation impact on bleeding risk during HoLEP: Monocentric study of 156 patients]. / Impact des anticoagulants sur le risque hémorragique au cours de l'HoLEP : étude monocentrique de 156 patients.

OBJECTIVE: Compare the length of hospital stay and the complications after HoLEP between three groups of patients: a control group, a group with antiplatelet therapy, a group with anticoagulation therapy. MATERIALS: Retrospective cohort study that included all consecutive patients who underwent HoLEP for prostatic hyperplasia in our center from may 2013 to may 2016. Anticoagulated patients and patients under clopidogrel had respectively a relay with heparine and aspirine. Patients were seen after surgery at 1 and 3 months. RESULTS: A hundred and fifty six patients were analysed, mean age was 70.7 years (DS 6.8), mean prostate volume 88.8g (DS 34.1). 106 patients were in the control group, 34 had antiplatelet therapy and 16 had anticoagulation therapy. There were no difference between the 3 groups for mean age, mean prostatic volume, PSA. There was also no difference for length of intervention, irrigated volume and length of morcellation between the three groups. There were no difference between patients in the control group and patients with antiplatelet therapy for length of hospital stay (2.1 days vs 2.0 days), lenght of urethral catheterization (1.6 days vs 1.5 days). There was a statistical difference between patients in the control group and patients with anticoagulation therapy for lenght of hospital stay (2.0 days vs 4.4 days; P=0.01), length of bladder irrigation (0.9 day vs 1.8 days; P=0.01), lenght of urethral catheterization (1.6 days vs 3.5 days; P=0.01). Transfusion rate was 18.75% (n=3) for patients with anticoagulation, 2.9% (n=1) for patients under antiplatelet therapy and 0.9% (n=1) for patients in the control group. CONCLUSION: Anticoagulation during HoLEP is a valid option but need to be proceed with carefully management. LEVEL OF PROOF: 4.

[Do initial experience with an enhanced recovery program after surgery (ERAS) improve postoperative outcomes after cystectomy?] / L'application d'un programme de réhabilitation précoce (ERAS) améliore-t-elle les résultats périopératoires après cystectomie ?

OBJECTIVE: To estimate the feasibility and the impact of an ERAS program after radical cystectomy for bladder cancer. MATERIALS AND METHODS: This was a retrospective study comparing a historical pre ERAS group, including all the patients undergoing cystectomy for bladder cancer from January 2013 to December 2015 with a classic procedure, and an interventional ERAS group after introducing an enhanced recovery protocol before, during and after surgery, from February 2016. The principal outcome was the postoperative length of stay. Secondary outcomes mesures were impact on perioperative complication rate (Clavien classification≥3B), readmission rate, reanimation length of stay, ileus rate and adherence to the ERAS protocol. RESULTS: There were no differences between the 2 groups as far as demographics characteristics are concerned. In total, 97 patients were included, 56 in the control group, and 41 in the ERAS group. The adherence to the protocol was about 65.8%. The ERAS group had statistically significantly shorter median length of stay (D19 versus D14; P: 0.021). The major complications rate (Clavien≥3B) were about 23.2% for the control group and 12.1% for the ERAS group (P: NS). The reinsertion of nasogastric tube were higher in the control group (39.3% vs 21.9%; P: NS) and the readmission rate was about 7.1% in the control group versus 14.6% in the ERAS group (P: NS). CONCLUSION: In conclusion, introduction and application of an enhanced recovery protocol (ERAS) after cystectomy for bladder cancer allowed for better management of postoperative outcomes. It is clearly feasible in cystectomy, and improve significantly the median postoperative length of stay. Moreover, it may be effective in terms of faster return of bowel function and reduction of majors complications. LEVEL OF EVIDENCE: 4.

[The W-shaped ileal neobladder: Long term functional outcomes and health-related quality of life]. / La néovessie iléale en W : résultats fonctionnels et qualité de vie à long terme.

PURPOSE: To evaluate functional outcomes and patients' health-related quality of life over ten years after a W-shaped ileal neobladder urinary diversion. PATIENTS AND METHODS: From 1994 to 2004, 87 patients with bladder cancer underwent a cystoprostatectomy with a W-shaped ileal neobladder. Among them, 31 patients (35.6%) were evaluated. The average follow-up was 158months, average age was 72years. We assessed functional outcomes (use of protections, USP score, uroflowmetry, postvoid residual volume), overall health-related quality of life (SF-36 score), and specific urinary-related quality of life (Ditrovie scale). RESULTS: Daytime continence was satisfactory in 29 patients (96.8%). Night-time continence was satisfactory in 27 patients (87.1%). Mean daytime continence, hyperactivity and dysuria scores of the USP were respectively 1.5/9, 3.2/21 and 2/9. Mean value of the maximum flow rate was 18mL/s for an average voiding volume of 324mL and an average postvoid residual volume of 70mL. The 8 dimensions of the SF-36 were all comparable with the French population's values. According to the Ditrovie scale whose average value was 1.83, the health-related quality of life was unchanged or little changed by urinary disorders in 28 patients (90.3%). CONCLUSIONS: Our results suggest that voiding status and health-related quality of life remain satisfactory over ten years after an orthotopic ileal neobladder derivation. LEVEL OF EVIDENCE: 5.

[Impact of neoadjuvant chemotherapy on therapeutic management of muscle-invasive bladder cancer]. / Impact de la chimiothérapie néoadjuvante sur la prise en charge des tumeurs de vessie infiltrant le muscle.

OBJECTIVE: Assess the toxicity of neoadjuvant chemotherapy (NAC), its impact on surgical schedule and postoperative morbidity of cystectomy for muscle-invasive bladder cancer (MIBC). PATIENTS AND METHODS: Retrospective multicentric study of 78 patients who underwent a cystectomy from January 2009 to March 2012 for MIBC. The following criteria have been studied: toxicity of NC (WHO classification), precystectomy interval, postoperative morbidity (Clavien), duration of stay, downsizing on CT-scan before cystectomy, and free of cancer pathology (pT0). RESULTS: Seventy-eight patients had been included, thirty-nine had a NAC. Thirty-three percent had a incomplete chemotherapy because of toxicity. Forty-eight percent had a significant toxicity and grade ≥ 3 toxicity was 33%. Median time between diagnosis and cystectomy was 12.6 weeks (0.7-38), 18 weeks with NAC (group 1) versus eight weeks without NAC (group 2) (P=0.01). In case of toxicity, the delay was 3.5 weeks longer (P=0.12). After cystectomy, 60% of patients had at least one postoperative complication; including 23% had major morbidity. NAC did not increase neither postoperative morbidity (P=0.15) nor duration of stay (18 vs 20 days; P=0.2). Radiological response rate to NC was 38%. pT0 rate was 79 vs 7.7%. The increase of precystectomy interval after NC did not worsen the pathological stage (P=0.5). CONCLUSION: NC had a high toxicity, but without impact on postoperative morbidity, and precystectomy interval did not have any impact on the prognosis. LEVEL OF EVIDENCE: 5.

[Effectiveness of flexible ureteroscopy versus extracorporeal shock wave lithotripsy for kidney stones treatment]. / Efficacité de l'urétéroscopie souple versus lithotritie extracorporelle dans le traitement des calculs du rein.

Primary endpoint was to objective a better effectiveness of flexible ureteroscopy (fURS) compared to extracorporeal shock wave lithotripsy (ESWL) 3 months after treatment of a unique kidney stone from 5 to 20mm. Secondary endpoints were to evaluate effectiveness in subgroup and tolerance. We conducted a prospective comparative randomised trial between May 2012 and February 2014. A computerised tomography was done before treatment and another 3 months after treatment. Of the 30 randomised patients, 8 dropped out from the study and 4 were lost to follow-up. Median time of follow-up was 3.82 months. In per-protocol analysis, success rate was 60% for fURS group versus 28.6% for ESWL group (P=0.29). In intention to treat analysis, success rate was 77.8% in fURS group versus 53.8% in ESWL group (P=0.38). In ESWL group, 5 patients (41.7%) needed a second treatment versus none in fURS group but it was not significant. During follow-up, 1 patient in each group presented a complication. Results of this feasibility study did not allowed to conclude on superiority of a technic. A multicenter study with more important enrollment is necessary considering economic side and tolerance of these treatments.

[Management of rectourethral fistulas with the York Mason procedure: surgical techniques and outcomes]. / Traitement des fistules uréthro-rectales par voie trans-anorectale de York Mason: technique et résultats.

OBJECTIVE: To report our experience for the management of urethro-rectal fistula by the York Mason technique. PATIENTS AND METHODS: We retrospectively analyzed the data of patients treated surgically for FUR by the technique of York Mason, between 2000 and 2012. RESULTS: Seventeen patients were included in the study. All patients had a bowel diversion before surgery. We observed four recurrences of FUR (23.5%). Recurrences occurred in a radiation field for two patients and in a oncologic recurrence for 1 patient. The fourth recurrence was treated by a second procedure of York Mason successfully. CONCLUSION: In our study, the York Mason technique was safe and reproducible for the treatment of FUR. The main factor of failure was a history of pelvic radiotherapy.

[Treatment of stress urinary incontinence after prostate surgery: results of the artificial urinary sphincter after suburethral sling failure]. / Traitement de l'incontinence urinaire d'effort après prostatectomie : résultats du sphincter urinaire artificiel après échec de bandelette sous-urétrale.

OBJECTIVE: To determine whether the presence of a previously implanted suburethral sling for post-prostatic surgery incontinence influences the outcomes of subsequent AUS implantation. PATIENTS AND METHODS: A retrospective study comparing 15 patients who underwent AUS placement after suburethral sling failure between November 2004 and December 2009 to 15 patients who underwent AUS placement as first-line treatment during the same period. Demographic characteristics, preoperative assessment of urinary incontinence and technique of implantation of the AUS were similar in the both arms. A USP(®) continence questionnaire was sent to patients by mail. Success was defined as a subjective improvement of the incontinence in patients using less than one pad per day. RESULTS: No perioperative incidents were noted in either arm. Mean operative time, the size of implanted cuffs, duration of catheterisation, length of hospital stay and postoperative complication rate, as well as the rate of surgical revision, were similar in both arms. The follow-up was slightly lower in the first arm (21 vs. 28.8 months, P=0.83). Stress incontinence and bladder overactivity scores of the USP(®) questionnaire, as well as success rates (73.3 vs. 80%, P=0.67), were equivalent in both arms. CONCLUSION: The results associated with the AUS procedure were not significantly different between men who had a suburethral male sling implanted before and those who had the AUS implanted as a first-line treatment.

[Complex renal tumors on solitary kidney: results of ex vivo nephron-sparing surgery with autotransplantation]. / Tumeurs rénales complexes sur rein unique : résultats de la chirurgie partielle ex vivo avec autotransplantation.

OBJECTIVE: To analyze the complications and the oncologic and functional results after ex vivo surgery and autotransplantation for the treatment of complex renal tumors. MATERIAL AND METHOD: From 1996 to 2009, 11 patients, mean age 54.8 years, underwent ex vivo nephron-sparing surgery and autotransplantation for malignant complex renal tumors (centrorenal or hilar topography) on an anatomic or functional solitary kidney. Three patients (27.2 %) were treated for a metastatic disease. RESULTS: Mean operative time was 340 minutes (240-440) and mean ischemia time was 162 minutes (110-231). Five patients (45.4 %) needed peroperative blood transfusion. Mean hospital stay was 21.5 days (8-50). Eight patients (72.7 %) suffered complications: two urinary fistulas, two early vascular thrombosis leading to nephrectomy and permanent dialysis, two pneumopathies and four acute tubular necrosis leading to temporary dialysis. There was no death among patients in early postoperative period. Tumors TNM staging ranged from pT1 to pT3aN0. Surgical positive margins were observed in three cases (27.2 %). With a mean follow-up of 37.8 months (3-144), the mean MDRD creatinine clearance was of 45.4 ml/min/1.73 m(2) and four patients (36.4 %) were presenting a complete remission. We observed two local recurrences (18.2 %) and five metastatic evolutions (45.4 %) leading to two deaths (18.2 %). CONCLUSION: Ex vivo nephron-sparing surgery was an acceptable option in the treatment of complex renal tumors for imperative indications, when in situ surgery appeared to be technically unfeasible. Despite a significative morbidity, long-term functional results were satisfying.

[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.

[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.

[Kidney transplantation and lower tract obstructive uropathy treated by Botox: a case report]. / Greffe rénale et uropathie obstructive du bas appareil traitée par Botox: à propos d'un cas.

INTRODUCTION: The indications for botulinum toxin have been extended in the field of urology, especially in vesicosphincteric dysfunction with good results. The authors report the use of botulinum toxin in a kidney transplant recipient with urethral hypertonia partly responsible for end-stage chronic kidney disease. CASE REPORT: Mr E.J, 25 years old, was operated for bilateral megaureter with vesicosphincteric dysfunction during childhood. He was managed in our department with serum creatinine of 364 mol/l. Ultrasound showed bilateral ureteropelvic dilatation and residual urine of 300 ml. Urodynamic assessment demonstrated a normally active bladder with normal compliance and urethral hypertonia. An intrasphincter injection of 300 units of Botox was performed in May 2003 with a good result for 11 months. He subsequently received a second intrasphincter injection of 200 units with clinical efficacy maintained for at least six months. This patient underwent living-donor kidney transplantation in May 2005. An intrasphincter injection of 100 units of Botox was performed nine days after transplantation, then every six months. With a follow-up of 16 months, renal function is stable with negligible residual urine. DISCUSSION: The use of botulinum toxin in non neurogenic urethral hypertonia has been reported in only a few original articles. Botulinum toxin injection into the striated sphincter of the urethra decreases urethral resistance, improving obstructive symptoms and can be effective in kidney transplant recipients.

[Dual kidney transplant: the E. Herriot Hospital Lyon experience]. / Bitransplantation rénale : expérience du protocole lyonnais de l'hôpital E.-Herriot.

INTRODUCTION: In the current context of a high incidence end-stage kidney disease and a shortage of organs for kidney transplantation, the increasing use of transplants considered to be "borderline" represents a potential source of transplants. Over the last 10 years, some centers have developed a transplantation strategy, which consists of transplanting two borderline kidneys that cannot be proposed separately in a single recipient. The authors report their experience of dual kidney transplant. MATERIALS AND METHODS: Since 2001, 15 dual kidney transplants have been performed in a single centre according to a local protocol based on the correspondence between the weight of the donor kidney and the recipient's weight, weighted by the number of fibrotic glomeruli observed on the initial biopsy. In this study, the authors analyze the postoperative complications and functional results observed in patients transplanted according to this protocol. RESULTS: Dual kidney transplants represented less than 5% of all transplants performed during the study period concerned, which remained lower than the objectives initially announced by the ABM. The surgical technique was left to the surgeon's discretion. The mean follow-up was 26.3 months. Fourteen of the 15 recipients were alive with a functional graft. Surgical complications were globally more frequent when kidneys were transplanted on the same side (versus transplanted on both sides). Mean serum creatinine was 119.4 mol/l at six months (creatinine clearance according to MDRD formula: 57.3 ml/min per 1.73 m2), 118.8 mol/l at 12 months (creatinine clearance: 55.8) and 132.4 mol/l at 24 months (creatinine clearance: 44.2). One year post-transplant, mean renal function measured by inulin clearance was 55.5 ml/min per 1.73 m2. Four of the 15 patients had experienced an episode of acute rejection and three patients experienced delayed return of transplant function. CONCLUSION: In view of the results obtained, the authors consider that dual kidney transplant could be a reasonable and effective option for selected patients. Positioning of the transplants in each iliac fossa limited the surgical complication rate.

[Surgical aspects of kidney transplantation in children (study of 148 cases)]. / Aspects chirurgicaux de la greffe rénale chez l'enfant (étude de 148 cas).

OBJECTIVE: Kidney transplantation is the best treatment for end-stage renal disease. This procedure is by now routinely used and permits children survival and rehabilitation. We describe the surgical complications of kidney graft in our paediatric experience. MATERIALS AND METHODS: From April 1987 to August 2000, 175 kidney transplantation were proceeded in the department of urology and transplantation in Edouard Herriot Hospital (Lyon). Twenty-nine kidneys (17%) were from living related donors and 146 (83%) were from cadaveric donors. We evaluated 148 kidney transplantation (132 patients) in 79 male and 53 female children. Mean age was ten years (range: seven months to 18 years). Twelve allografts were from living related donors and 136 cadaveric donors. RESULTS: Twelve patients died of various medical complications. One patient was lost of sight. Surgical complications were postoperative bleeding, lymphocele, urologic and digestive troubles. The rest of our patients had uneventful evolution. CONCLUSION: A general commitment is the only way to promote organ donation and enable patients with terminal renal failure to have access to renal transplantation.

Nephron-sparing surgery for renal cell carcinoma: detailed analysis of complications over a 15-year period.

PURPOSE: To assess the incidence of complications of conservative renal surgery for renal cell carcinoma in both elective and imperative indications, and its evolution over a 15 year period. PATIENTS AND METHODS: From 1988 to 2003, 127 patients underwent partial nephrectomy or tumorectomy for renal cell carcinoma in our department. INDICATIONs were imperative in 42% (n = 53) and elective in 58% (n=74) of cases. Morbidity was retrospectively assessed according to four parameters: 1- Period of surgery: A, from 1988 to 1999 and B, from 2000 to 2003. 2- INDICATION: elective vs. imperative. 3- experience of surgeon: senior vs. junior. 4- Nature of complications: minor or major. Comparative analysis was conducted using Chi-square and Fischer exact tests. RESULTS: Global incidence of complications was 30.7% (n = 39) corresponding to 18.1% minor (n = 23) and 12.6% (n = 16) major complications. Results show a moderate decrease of complication rate during Period B: 28.1% versus 32.9% during period A (p = 0.69). Complications occurred more frequently in imperative indications (49.1%) than in elective indications (17.6%) (p = 0.002), mostly regarding major complications (respectively 28.3% and 1.4%. (p < 0.001)). Overall re-intervention rate was 15.7%: 22.6% in imperative and 10.8% in elective indications (p = 0.008). Mean length of hospital stay was 14.1 days and significantly longer during period A (p = 0.003) and in imperative indications (p = 0.009). CONCLUSION: In our study, conservative renal surgery has a significant rate of complications which is extremely variable regarding to different parameters. Most discriminating factor was indication: in imperative indications, we observed a high rate of major complications (28.3%) that we consider acceptable to prevent anephria in clearly informed patients. Major complications are exceptional in elective indications. Decreased incidence of complications during the later period (B) is modest, and the role played by systematic pedicular clampage is discussed. As results published in medical literature are difficult to compare, we agree with authors who recently proposed to standardize complications data analysis, using a gravity scale, in order to provide relevant information to patients about statistical risks before surgery.
