- Abstract
Les recommandations actuelles du CCAFU pour les TVNIM à faible risque sont une dose unique de chimiothérapie intravésicale (IPOP) ou à défaut une irrigation vésicale continue (IVC) puis la surveillance. En pratique l’IPOP est peu réalisée en France et bien que l’IVC soit devenue un standard, la durée d’irrigation varie beaucoup en fonction des centres. Notre objectif principal était de déterminer si la réduction de la durée de l’irrigation vésicale continue à moins de 6 heures après RTUV diminuait la survie sans récidive à un an par rapport aux patients irrigués toute la nuit.

- Abstract
La chirurgie ambulatoire est une priorité médico-économique car elle optimise la rééducation post opératoire tout en désengorgeant les services hospitaliers. La résection transurétrale des tumeurs de la vessie (RTUV) en ambulatoire est peu répandue (5 % des patients). Notre objectif était d’évaluer la faisabilité de la RTUV en ambulatoire ainsi que les facteurs éventuellement associés aux complications postopératoires.

- Abstract
Objectives: Urosepsis currently accounts for half of all post flexible ureterorenoscopy (F-URS) complications, with an incidence of up to 4.3%. It represents a quarter of all septic episodes in adults and 2% of hospital spendings. The primary objective of this study was to define the predictive clinical parameters that increase the risk of urosepsis after F-URS., Subjects/patients (or Materials) and Methods: This prospective multicentric study evaluated patients who underwent F-URS for calculus between June 2016 and June 2018 in eleven French centers. Clinical, bacteriological, morpho-constitutional stone data, intraoperative information and complications were compared. Risk factors for postoperative urosepsis were identified and analyzed., Results: We included 486 F-URS in 432 patients. The ureter was prepared using a double J stent in 51% of cases, a digital endoscope was used in 56% of patients with a median operative time of 120 min IQR (90-125) and using a sheath in 90% of cases. Postoperative urosepsis was observed in 18 patients (4%) with a median time to onset of 2 days IQR (1-5). The presence of coronary insufficiency: 3 (17%) vs 14 (3%) p = 0.005, a larger stone diameter: 11 cm [9-17] vs 10 cm [8-13] p = 0.02, a positive preoperative urine culture even when treated: 3 (17%) vs 56 (12%) p = 0.04, as well as the final composition of the type IV calculus (carbapatite or struvite) 5 (28%) vs 20 (4%) p < 0.001, were significantly associated with the occurrence of urosepsis. In multivariate analysis, only the presence of a type IV stone (OR = 14.0; p = 0.025) remained significant., Conclusion: Ureteroscopic treatment of a type IV stone (carbapatite or struvite) in a patient should raise concerns about the risk of post-operative urosepsis. When recognized intraoperatively, they should lead to a pyelic urinary sample and prolonged clinical surveillance., (© 2024.

- Abstract
Background: Advances in chromatography and mass spectrometry have allowed us to develop a novel technique for measuring intraprostatic hormone concentrations directly on prostate needle biopsies, rather than using traditional punch excision. This has significant clinical implications as intraprostatic dihydrotestosterone and testosterone levels could help monitor prostate growth, neoplasia and castration resistance., Methods: Patients undergoing radical cystoprostatectomy for bladder cancer were prospectively included. Each prostate specimen received one 90mg punch excision and six needle biopsies. Intraprostatic hormones were dosed through gas chromatography-mass spectrometry., Results: We included twenty patients, of which eleven were incidentally diagnosed with prostate cancer; four had ISUP 1 (20%) and seven had ISUP 2 (35%). The prostate biopsy technique was unable to obtain measures for testosterone, Delta-4-androsterone and androstenedione. Tissue concentrations of DHEA, DHT, E1 and E2 can be obtained with no significant difference from the reference established on a punch from a single biopsy core sample., Conclusions: Our study demonstrates that intraprostatic concentrations of DHEA, DHT, E1 and E2 can be measured without significant difference from the reference established on a single punch excision. This finding opens the way to research on the interactions between endocrinology and prostate oncogenesis and particularly on the mechanisms of resistance to hormone therapies in vivo., (Copyright © 2024 Société Française du Cancer.

- Abstract
Background: C-reactive protein is a useful biological tool to predict infectious complications, but its predictive value in detecting organ-specific surgical site infection after liver resection has never been studied. We aimed to evaluate the predictive value of c-reactive protein and determine the cut-off values to detect postoperative liver resection-surgical site infection., Methods: A multicentric analysis of consecutive patients with liver resection between 2018 and 2021 was performed. The predictive value of postoperative day 1, postoperative day 3, and postoperative day 5 C-reactive protein levels was evaluated using the area under the receiver operating characteristic curve. Cut-off values were determined using the Youden index in a 500-fold bootstrap resampling of 500 patients treated at 3 centers, who comprised the development cohort and were tested in an external independent validation cohort of 166 patients at a fourth center., Results: Among the 500 patients who underwent liver resection of the development cohort, liver resection-surgical site infection occurred in 66 patients (13.2%), and the median time to diagnosis was 6.0 days (interquartile range, 4.0-9.0) days. Median C-reactive protein levels were significantly higher on postoperative day 1, postoperative day 3, and postoperative day 5 in the liver resection-surgical site infection group compared with the non-surgical site infection group (50.5 vs 34.5 ng/mL, 148.0 vs 72.5 ng/mL, and 128.4 vs 35.2 ng/mL, respectively; P < .001). Postoperative day 3 and postoperative day 5 C-reactive protein-level area under the curve values were 0.76 (95% confidence interval, 0.64-0.88, P < .001) and 0.82 (95% confidence interval, 0.72-0.92, P < .001), respectively. Postoperative day 3 and postoperative day 5 optimal cut-off values of 100 mg/L and 87.0 mg/L could be used to rule out liver resection-surgical site infection, with a negative predictive value of 87.0% (interquartile range, 70.2-93.8) and 76.0% (interquartile range, 65.0-88.0), respectively, in the validation cohort., Conclusion: Postoperative day 3 and postoperative day 5 C-reactive protein levels may be valuable predictive tools for liver resection-surgical site infection and aid in hospital discharge decision-making in the absence of other liver-related complications., (Copyright © 2024 Elsevier Inc.

- Abstract
Introduction: Endoscopic surgery is the standard treatment for benign prostatic hyperplasia (BPH) refractory to pharmacological treatments. In order to reduce invasiveness and preserve sexual function, prostatic artery embolization (PAE) has been developed. However, the technical difficulties of carrying out this procedure and the results, which have yet to be confirmed, mean that it is not currently recommended. The seriousness of the complications generated should lead to a reflection on the benefit-risk balance. The objective is to report a case of penile ischemia after embolization of the prostatic arteries., Material and Method: A severe complication following prostatic artery embolization (PAE) is reported with its clinical and paraclinical evaluation before and after the procedure as well as the therapeutic management., Results: Penile necrosis following prostatic artery embolization was reported in a 75-year-old patient despite an attempt of deobstruction. Lower urinary tract symptoms worsened postoperatively, associated with glans necrosis and refractory erectile dysfunction., Conclusion: The place of PAE in the therapeutic arsenal of BPH needs to be confirmed. This innovative technique exposes the patient to potentially severe risks such as penile ischemia, not encountered in conventional endoscopic surgical treatment. PAE should not be included in the therapeutic armamentarium for BPH outside of clinical trials., (Copyright © 2023 Elsevier Masson SAS. All rights reserved.)

- Abstract
Purpose: Radical cystectomy (RC) is currently the standard of care for non-metastatic muscle invasive bladder cancer. Few studies compare methods of cutaneous continent urinary diversion (CCUD) following RC. The objective was to compare perioperative morbidity and functional outcomes of CCUD using an ileal pouch with a Mitrofanoff efferent versus a Miami ileocolic pouch in patients undergoing cystectomy of pelvic exenteration for bladder cancer., Methods: This retrospective two-centre study included all consecutive patients who underwent radical cystectomy or pelvic exenteration with CCUD for bladder cancer between 2001 and 2020 in two academic French hospitals with a median follow-up time of 5.4 years. Patients were divided into two groups according to the type of urinary diversion: Miami ileocolonic pouch (group A) and ileal pouch with Mitrofanoff/Monti principle (group B). Continence rate, ability to perform intermittent self-catheterisation, complications and health-related quality of life (HRQoL) measured by the bladder cancer index were evaluated., Results: Thirty-one patients were included. Continence was achieved in 11 out of 14 patients (79%) in group A versus 12 out of 17 patients (71%) in group B (P = 0.3). A significantly higher rate of cutaneous tube stenosis was reported in group B compared to group A (eight (47%) vs. one (7%) patient, respectively; P = 0.02). HRQoL outcomes were similar in both groups except less digestive discomfort observed in group A., Conclusions: When comparing the ileal pouch with Mitrofanoff/Monti's principle with a Miami pouch, no significant differences were found regarding continence rate, ability to self-catheterise, long-term complication rate and overall patient satisfaction., (© 2022.
