[Cost comparison of open and robot-assisted partial nephrectomy in treatment of renal tumor]. / Comparaison médico-économique de la laparoscopie robot-assistée et de la lombotomie pour la réalisation de néphrectomies partielles pour cancer du rein.

INTRODUCTION: Robot-assisted partial nephrectomy rapidly took on among urologists, even though studies showing its superiority over other techniques are still scarce and its costs hard to evaluate, especially in the French medical system. OBJECTIVE: To evaluate the cost overrun of robot-assisted partial nephrectomy compared to that of open partial nephrectomy. EQUIPMENT AND METHODS: From January 2010 to December 2013, 77 patients underwent a partial nephrectomy, 46 of which by robot-assisted laparoscopy and the remaining 31 by lombotomy. The two groups were similar in composition. Economic data regarding the staff, the consumables and the premises involved have been analyzed. RESULTS: Costs are significantly higher in the NPR group (9253.21 euros vs. 7448.42 euros) due to higher consumable expenses as well as the costs pertaining to the amortization and maintenance of the robot. Yet, that difference tends to diminish as the duration of the experiment increases. No significant difference was found in warm ischemia times, operation duration and renal function a month after the operation. On the other hand, patients from the NPR group spent a significantly smaller amount of time in recovery room (159 minutes vs. 205 minutes, P=0.004), presented fewer complications and were discharged faster (6.1 days vs. 8.1 days, P=0.04). CONCLUSIONS: To be profitable for the hospital in the French GHS system, robot-assisted partial nephrectomy must take place in a complex where at least 300 robot-assisted interventions are performed annually, in the framework of a hospitalization lasting four days or less, the use of a single needle holder and no systematic use of a haemostatic agent.

[Efficacy of periurethral injections of polyacrylamide hydrogel (Bulkamid(®)) and quality of life of patients with urinary incontinence due to sphincter deficiency (IUE-IS)]. / Efficacité des injections péri-urétrales de polyacrylamide hydrogel (Bulkamid(®)) et qualité de vie de patientes souffrant d'incontinence urinaire d'effort par insuffisance sphinctérienne (IUE-IS).

INTRODUCTION: This study was carried out to evaluate the efficacy of periurethral injection of polyacrylamide hydrogel (PAHG, Bulkamid(®), Ethicon) for the treatment of female stress urinary incontinence (SUI). METHODS: Single-center prospective study: periurethral injection of Bulkamid(®) was performed in 80 patients with severe urinary incontinence between June 2010 and October 2011. The evaluation of the impact on quality of life was carried out using the Patient Global Impression of Severity (PGI-S), the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) and Patient Global Impression of Improvement (PGI-I) before and after treatment. RESULTS: With a mean follow-up of 18.6 ± 5.3 months, 60% of patients had improved. For 30/74 (40%) there was no improvement and no patient had worsening of PGI-I after injection. Before surgery, 55.4% of patients considered their condition as severe (PGI-S). After injecting 21/74 (28%) and 11/74 (15%) considered it normal and severe (zero leakage). The ICIQ -SF score increased from 17 ± 2.84 before injection to 13 ± 5.52 after surgery, with a significant 30% decrease (P<0.00001). The reinjection rate was 29%. The complication rate was 16% (17/108): 11 cases of transient postoperative retention, 2 cases of cystitis, dysuria four episodes. No abscess or infection at the injection site, no specific complication to the product used. CONCLUSION: With an (PGI-I) improvement rate of 60 and 15% of patients without leakage (PGI-S/ICIQ), periurethral injection of Bulkamid(®) is an effective and safe treatment option for women with a severe urinary incontinence especially in therapeutic failure.

[Consequences of coelioscopic sacrocolopoxy on the sexuality of the couple]. / Impact des cures de prolapsus pelviens par promontofixation laparoscopique sur la sexualité du couple.

AIM: To assess the impact on the sexuality of the couple of pelvic organ prolapse repair with coelioscopic sacrocolopoxy. MATERIAL: Pilot, prospective, monocentre study conducted in Nîmes university hospital. Consecutive patients undergoing coelioscopic sacrocolpopexy and their partner were invited to participate. Women attended a pre-surgical visit and a 6-month post-surgery visit where pelvic organ prolapse status was clinically assessed. In the same time, they and their partner filled general quality of life and specific sexual quality of life questionnaires (questionnaires PISQ12, PFDI-20 in women, medical history, IIEF, modified PISQ12 questionnaires in men). RESULTS: From May to December 2010, 25 couples were assessed. Anatomical success rates (POPQ<2) in the middle, anterior and posterior compartments were respectively of 100%, 95.4% and 66.7%. After surgery, 65.2% of pairs (n=15) reported an at least hebdomadal frequency of sexual intercourse, as compared with 54.2% (n=13) of pairs before surgery (P<0.001). Two cases of decrease of sexual intercourses frequency were reported and appeared partner-related. There was an overall non-significant improvement in sexual quality of life in men and women. General pelvic organ distress, urinary incontinence and specific pelvic organ prolapse distresses were significantly improved after surgery. CONCLUSION: Coelioscopic sacrocolpopexy does not impair couple's sexuality, assessed as sexual intercourses frequency and could even improve it. Partner's assessment can bring important information with respect to the interpretation of functional sexual results of surgery.

[Treatment of women urinary incontinence by artificial urinary sphincter: efficacy, complications and survival]. / Traitement de l'incontinence urinaire par sphincters urinaires artificiels chez la femme : efficacité, complications et survie.

OBJECTIVE: To analyze long-term results and mechanical survival of the artificial urinary sphincter (AUS) AMS 800™ (American Medical Systems, Minnetonka, MN, USA) in women with stress urinary incontinence (SUI) due to intrinsic sphincter deficiency (ISD). PATIENTS AND METHODS: Data were collected prospectively from women treated for SUI at one university hospital between 1987 and 2007. Inclusion criteria was SUI with severe ISD defined by low urodynamic closure pressure and negative continence tests. Endpoints were survival, complications and continence. RESULTS: A total of 376 AUS were implanted in 344 patients with a median age of 57 years (18-93 years). The median follow-up was 9 years (3-20 years). The 3, 5, and 10 years global device survival were 92, 88.6, and 69.2% respectively. The mean mechanical survival was 176 months (14.7 years). The two main risk factors for decreased AUS survival were the number of previous incontinence surgeries and the presence of neurogenic bladder. The continence rates assessed as full (no leakage) in 85.64% patients, social (some drops but no pad) in 8.78% and incontinence (1 pad or more) in 5.58%. CONCLUSIONS: The study has shown that in patients with ISD, the AUS represents an effective process, durable with an acceptable rate of complication.

[Functional MRI by general radiologists in prediction of side-specific extracapsular extension after radical prostatectomy: what value in daily practice?]. / IRM fonctionnelle par des radiologues généralistes, dans la prédiction de l'extension extracapsulaire lobe spécifique après prostatectomie radicale : quelle valeur en pratique quotidienne ?

OBJECTIVE: To evaluate the performance of functional MRI (FMRI) performed by general radiologists (GR) in detection of side-specific extracapsular extension (SSECE) prostate cancer (PCa). METHODS: We retrospectively analyzed 79 patients who underwent FMRI with pelvic phased array coil before radical prostatectomy (RP) performed at University Hospital (UH) of Nîmes. Twelve GR (including three from UH) interpreted the images during their daily practice. FMRI results were dichotomized as positive or negative and confronted to pathological reports for SSECE and side-specific seminal vesicle invasion (SSSVI), with calculation of diagnostic values. The influence of interval between biopsy and FMRI, diffusion-weighted sequence (DWS) and intensity of FMRI, on the diagnostic performance were assessed by Fisher's exact test. RESULTS: A SSECE and a SSSVI were observed at FMRI and pathology respectively on 14 (8.8%) and 38 (24.1%) prostate lobes, and on six (3.8%) and seven (4.4%) prostate lobes. The sensitivity, specificity, positive and negative predictive values of FMRI for SSECE were respectively 24%, 96%, 64% and 80%; and for SSSVI were 14%, 97%, 17% and 96% respectively. The time between biopsy and FMRI, intensity of FMRI and DWS, did not influence the sensitivity and specificity of fMRI at Fisher test. CONCLUSION: This study found that preoperative prostate FMRI performed by GR has good specificity but poor sensitivity in predicting SSECE on pathological reports.

[Interest of flexible videocystoscopy in blue light (+Hexvix(®)) in consultation for the diagnosis of vesical tumor]. / Intérêt de la vidéocystoscopie souple en lumière bleue (+Hexvix(®)) en consultation pour le diagnostic des tumeurs de vessie.

OBJECTIVES: Estimate the feasibility and the results of the realization in consultation of a flexible videocystoscopy in blue light preceded by an instillation of Hexvix(®) (GE Healthcare) for the initial diagnosis or the surveillance of vesicals tumors (VT). The objective of this study was to compare the number of hurts seen in white light and in blue light, and to estimate in which percentage of case the use of the Hexvix(®) in consultation modified the care. PATIENTS AND METHODS: Thirty consecutive patients (26 men and four women) were estimated prospectively by vesical videofibroscopy in blue light (Wolf's PD videofibroscope) realized 1 hour after an endovesical instillation of Hexvix(®). All the examinations were realized in external consultation under local anesthetic by xylocaine gel: 23 (76.6%) patients within the framework of a surveillance of VT and seven (23.4%) for the diagnosis of a hematuria with normal echography. When a suspect hurt or a VT was discovered, the patients benefited from an endoscopic resection under anesthesia with new cystoscopy in blue light. RESULTS: Suspect hurts were revealed in 10 out of 30 patients, five in white and blue light, five in blue light only. Among the five only visible hurts in blue light, three were urothelial tumors (any pTa of bottom-rank, less of 5 mm) and two non-specific hurts. No CIS's hurt was revealed during this study. The fibroscopy in blue light allowed to diagnose invisible hurts in white light in three patients (10%) and has modified the care of five patients (16.7%). The duration of the cystoscopy was on average of 9.5 minutes. The tolerance of the examination was good and no complication arose. CONCLUSION: The use of the flexible videocystoscopy in blue light +Hexvix(®) has allowed to improve the rate of detection of VT. Except CIS's hurts, this improvement was bound to the diagnosis of little aggressive small-sized VT. The indications must be specified by studies of bigger scale and a medical economic evaluation.
