Quality of life associated with orthotopic neobladder and ileal conduit in women: A multicentric cross-sectional study.

PURPOSE: To compare quality of life and functional outcomes associated with orthotopic neobladder (ONB) and ileal conduit (IC) after anterior pelvic exenteration for bladder cancer in women, through a multicentric cross-sectional study. METHODS: All women who have undergone an anterior pelvic exenteration associated with ONB or IC for a bladder cancer between January 2004 and December 2014 within the three participating university hospital centers and that were still alive in February 2016 were included. Three distinct auto-administered questionnaires were submitted to the patients: the EORTC QLQ-C30, the EORTC QLQ-BLmi30 and the SF-12. Comparison of response to these questionnaires between women with ONB and those with IC were studied with Mann-Whitney U tests, with a statistically significant P-value set at<0.05. The primary endpoint was the "global health status" sub-score extracted from the EORTC QLQ-C30 questionnaire. The secondary endpoints were the functional sub-scores and symptoms sub-scores obtained with the EORTC QLQ-C30 questionnaire as well as the sub-scores obtained with the EORTC QLQ-BLmi30 and the SF-12 questionnaires. RESULTS: Forty women were included in the study (17 ONB, 23 IC). The primary endpoint was comparable between the ONB and IC women (83.3 vs. 66.7 P=0.22). Similarly, no significant statistical difference could be pointed between the ONB and IC women in terms of secondary endpoints. CONCLUSION: The present study did not report any significance difference in terms of quality of life and functional outcomes between women with ONB and those with IC after pelvic exenteration for bladder cancer.

Routine enema before urodynamics has no impact on the quality of abdominal pressure curves: Results of a prospective controlled study.

AIMS: The presence of stools in the rectum might affect the quality of the abdominal pressure curve during filling cystometry, but, to date, no study has evaluated the impact of bowel preparation before urodynamics. We evaluated the influence of a sodium phosphate enema before urodynamics on the quality of the abdominal pressure curve. METHODS: A prospective, controlled, single-blind study was conducted in a single center from May to June 2013. The patients were divided into 2 consecutive groups: patients seen in outpatient clinics during the first 6 weeks (group A) who underwent urodynamics without bowel preparation and patients seen in outpatient clinics during the second 6 weeks (group B) who had a prescription of sodium phosphate enema before urodynamics. The primary endpoint was the quality of the abdominal pressure curve evaluated independently by three physicians who were blinded to the study group. The following data were also collected: age, gender, the presence of a neurological disorder, complicated nature of urodynamics and bother related to preparation for it, assessed using a Likert scale (0 to 10), and the equipment used. A per protocol analysis and an intent-to-treat analysis were conducted. RESULTS: One hundred and thirty-nine patients were included: 54 in group A and 85 in group B. One-third of patients had neurological conditions. 14 patients in group B did not perform their scheduled enema. Thus, 68 patients performed an enema before urodynamics and 71 did not. There was no difference between groups A and B regarding the complicated nature of urodynamics (Likert scale: 3.12 vs. 3.18; P=0.91) or bother related to preparation for it (Likert scale: 3.46 vs. 2.97; P=0.43). In the per protocol analysis, the abdominal pressure curve was considered perfectly interpretable (PI) in 69% of patients who did not receive an enema before urodynamics and in 65% of patients who did (P=0.61). The between-group difference was not statistically significant in intent-to-treat analysis (P=0.99). In patients who did not receive an enema before urodynamics, the only factors statistically associated with better quality of abdominal pressure curves were age <60years (P=0.001) and the urodynamic equipment used (Dantec®>Laborie®; P=0.01). CONCLUSION: In this prospective study, routine enema before urodynamics did not improve the quality of the abdominal pressure curve and did not increase the complicated nature of urodynamics or the bother of preparation for it.

[Oncologic and perioperative outcomes of robot-assisted radical cystectomy: A single-center prospective series]. / Résultats oncologiques et périopératoires de la cystectomie totale robot-assistée pour cancer : une série prospective monocentrique.

INTRODUCTION: The aim of this study was to report perioperative and oncological outcomes of robot-assisted radical cystectomy (RARC) in a single-center series and to evaluate the impact of the experience on perioperative outcomes. METHODS: Between March 2012 and January 2016, 41 patients underwent RARC associated with extended pelvic lymphadenectomy for muscle-invasive bladder cancer. All RARC included were performed by a single-surgeon in one center. Perioperative and oncological datas were collected prospectively. Recurrence-free (RFS), overall (OS) and cancer-specific survivals (CSS) were estimated using the Kaplan-Meier Method. The impact of the experience on perioperative data was estimated using Spearman's correlation test. RESULTS: Mean age was 67,7years (±10.6). Most patients underwent neoadjuvant chemotherapy (73.2%). Mean operative time and mean estimated blood loss were respectively 319.5minutes (±85.3) and 662.5mL (±360.9). Eight patients needed perioperative blood transfusion (19.5%). Conversion to open surgery was necessary in 3 cases (7.3%). Ileal neobladder was performed in 26.8% of the cases (54.5% being performed intracorporeal), and non-continent urinary diversion in 73.2%. Mean nodal yield was 17.7 (±9.3). Positive surgical margins were observed in 1 patient (2.3%). Mean length of stay was 13.2 days (±9.8). Postoperative complication rate was 46,3%. After a median follow-up of 16months, estimated 2 year-OS and CSS were respectively 62 and 76.1%. Estimated 2-year RFS was 67.6%. Perioperative outcomes improved with experience with a significant decrease in operative time (P=0.04) and a significant increase of nodal yield (P=0.05). CONCLUSION: In this single-center prospective study, satisfactory perioperative and oncological outcomes after RARC were observed despite the learning curve. Perioperative outcomes improved with surgeon's experience. Further studies are needed to confirm these findings. LEVEL OF EVIDENCE: 4.

[Impact of the acquisition of a flexible ureteroscope on the management of upper urinary tract stones in children]. / Impact de l'acquisition d'un urétéroscope souple sur le traitement des calculs du haut appareil urinaire chez l'enfant.

INTRODUCTION: Firstly reported in the early 1990s for the treatment of upper urinary tract stones in adult patients, flexible ureteroscopy (F-URS) has been used in children during the past 10 years and is now considered as a viable, but still second-line alternative to extracorporeal shockwave lithotripsy in these patients (ESWL). The aim of this study was to assess the impact of the acquisition of a F-URS on the management of upper urinary tract stones in children. PATIENTS AND METHODS: Data of all ESWL, F-URS and percutaneous nephrolithotomy performed for upper urinary tract stones in children from 0 to 18 years old in a single center from 2000 to 2014 have been collected retrospectively. Patients have been divided into two groups: group 1 before the acquisition of the F-URS (2000-2008) and group 2 after the acquisition of the F-URS (2008-2014). Preoperative data and peri-operative outcomes were compared between both groups using the χ(2) test and Fisher exact test for discrete variables and the Mann-Whitney test for continuous variables. RESULTS: Thirty-seven children have been treated during the first era and 32 during the second one. The two groups were similar in terms of age (7.2 years vs 8.1 years; P=0.54), size of the largest stone (15 mm vs 16.2mm; P=0,56) and number of stones per patient (1.4 vs 2; P=0,07) but the sum of stone diameters was higher in group 2 (16.9 mm vs 24.2mm; P=0,048). The stone-free rates were comparable in both groups (28.1% vs 32.2% after the first procedure; P=0.72), as were the mean number of procedures per patient (2.4 vs 2.5; P=0.78), the total length of stay (2.7 days vs 2.9 days; P=0.77), and the number of patients who experienced at least one complication (37.8% vs 40.6%; P=0.87). CONCLUSION: The acquisition of a F-URS allowed the treatment of more complex stones with a similar efficacy and without increasing morbidity. Further studies are needed to define the role of F-URS in the management of upper urinary tract stones in children.
