RESUMO

OBJECTIVE: To evaluate predictive factors of urinary incontinence (UI) after holmium laser enucleation of the prostate (HoLEP). METHODS: Patients (n = 2346) were included in a retrospective multicentric study from April 2012 to November 2017. Patients' characteristics (age, BMI, percentage with diabetes), preoperative data (IPSS score, whole gland volume, urinary drainage), operative data (enucleation time, enucleation efficiency, tissue enucleated weight, total delivered energy) and postoperative data were recorded. Absence of UI was defined as no pads at 3 and 6 months. Surgeon experience was stratified in three categories: beginners (< 21 cases), intermediate (21-40 cases) and experienced (> 40 cases). Multivariate logistic regression analysis was performed. RESULTS: UI was observed in 14.5% of patients (340/2346) at 3 months (95%CI 13-16%) and in 4.2% (98/2346) at 6 months (95%CI 3-5%). On multivariate analysis at 3 months, increasing age (OR per SD = 1.3 [1.14-1.48]), elevated BMI (OR per SD = 1.23 [1.09-1.38]), preoperative urinary drainage (OR = 0.62 [0.45-0.85]), increasing enucleated tissue weight (OR per SD = 1.29 [1.16-1.45]) and experienced surgeon with at least 40 cases (OR = 0.56 [0.42-0.75]) were significantly associated with UI. At 6 months, increasing age (OR per SD = 1.25 [1.01-1.53]), elevated BMI (OR per SD = 1.25 [1.03-1.5]), increasing whole gland volume (OR per one SD log = 1.24 [1.01-1.53]) and diabetes disorder (OR = 1.7 [1.03-2.78]) were significantly associated with UI. CONCLUSION: UI after HoLEP was observed in 14.5% of patients at 3 months and 4.2% at 6 months, with stress UI in half of the cases. Surgeon experience with at least 40 cases was the main predictive factor of 3 months UI after HoLEP and diabetes disorder of persistent UI at 6 months.

RESUMO

PURPOSE: Ejaculatory dysfunction is the most common side effect related to surgical treatment of benign prostatic obstruction (BPO). Nowadays, modified surgical techniques and non-ablative techniques have emerged with the aim of preserving antegrade ejaculation. Our objective was to conduce a systematic review of the literature regarding efficacy on ejaculatory preservation of modified endoscopic surgical techniques, and mini-invasive non-ablatives techniques for BPO management. METHODS: A systematic review of the literature was carried out on the PubMed database using the following MESH terms: "Prostatic Hyperplasia/surgery" and "Ejaculation", in combination with the following keywords: "ejaculation preservation", "photoselective vaporization of the prostate", "photoselective vapo-enucleation of the prostate", "holmium laser enucleation of the prostate", "thulium laser", "prostatic artery embolization", "urolift", "rezum", and "aquablation". RESULTS: The ejaculation preservation rate of modified-TURP ranged from 66 to 91%. The ejaculation preservation rate of modified-prostate photo-vaporization ranged from 87 to 96%. The only high level of evidence studies available compared prostatic urethral lift (PUL) and aquablation versus regular TURP in prospective randomized-controlled trials. The ejaculation preservation rate of either PUL or aquablation compared to regular TURP was 100 and 90 versus 34%, respectively. CONCLUSIONS: Non-ablative therapies and modified endoscopic surgical techniques seemed to be reasonable options for patients eager to preserve their ejaculatory functions.

RESUMO

BACKGROUND: Since the 1950s, preoperative medical preparation has been widely applied in patients with pheochromocytoma to improve intraoperative hemodynamic instability and postoperative complications. However, advancements in preoperative imaging, laparoscopic surgical techniques, and anesthesia have considerably improved management in patients with pheochromocytoma. In consequence, there is no validated consensus on current predictive factors for postoperative morbidity. The aim of this study was to determine perioperative factors which are predictive for postoperative morbidity in patients undergoing laparoscopic adrenalectomy for pheochromocytoma. STUDY DESIGN: It is a retrospective analysis of prospectively maintained databases in five medical centers from 2002 to 2013. Inclusion criteria were consecutive patients who underwent non-converted laparoscopic unilateral total adrenalectomy for pheochromocytoma. RESULTS: Two-hundred and twenty-five patients were included. All-cause and cardiovascular postoperative morbidity rates were 16% (n = 36) and 4.8% (n = 11), respectively. Preinduction blood pressure normalization after preoperative medical preparation had no impact on postoperative morbidity. However, past medical history of coronary artery disease (OR [CI95%] = 3.39; [1.317-8.727]) and incidence of intraoperative hemodynamic instability episodes (both SBP ≥ 160 mmHg and MAP < 60 mmHg) (OR [CI95%] = 3.092; [1.451-6.587]) remained independent predictors for postoperative all-cause morbidity. Similarly, past medical history of coronary artery disease (OR [CI95%] = 14.41; [3.119-66.57]), female sex (OR [CI95%] = 12.05; [1.807-80.31]), and incidence of intraoperative hemodynamic instability episodes (both SBP ≥ 200 mmHg and MAP < 60 mmHg) (OR [CI95%] = 4.13; [1.009-16.90]) remained independent predictors for postoperative cardiovascular morbidity. CONCLUSIONS: This study identifies risk factors for cardiovascular and all-cause postoperative morbidity after laparoscopic adrenalectomy in current clinical setting. These data can help physicians to guide intra-operative blood pressure management and have to be taken into account in further studies.

RESUMO

INTRODUCTION: To describe an original method for managing prolonged urinary leakage after partial nephrectomy. We placed a Malecot catheter in the ureter to improve the urinary drainage and therefore avoid the renal percutaneous treatment of the fistula or potential open surgery. TECHNICAL CONSIDERATIONS: We performed ureteral stenting using a 16 F Malecot catheter in 3 patients who had a prolonged urinary fistula after partial nephrectomy in which the placement of a ureteral stent could not resolve the urine leak. Drainage using 2 ureteral catheters was performed, which proved to be insufficient for the urinary fistula to resolve. We subsequently placed in the dilated ureter a 16 F Malecot catheter into the renal pelvis using a cystoscopic approach and a bladder catheter to complete the drainage. In all cases, the urine leak stopped after stenting with the Malecot catheter. At 1 month after the stenting, computed tomography and magnetic resonance imaging showed complete healing of the fistula. No infection or secondary ureteral stricture was reported. CONCLUSION: This technique with a low complication profile can be used as an additional endoscopic step, before more invasive procedures.

RESUMO

OBJECTIVE: To evaluate the use of a single needle driver with the V-Loc (Covidien, Dublin, Ireland) running suture and compare this with the use of 2 needle drivers with polyglactin interrupted sutures (IS) in dividing the dorsal venous complex (DVC) and forming the urethrovesical anastomosis (UVA) during robot-assisted radical prostatectomy (RARP). MATERIALS AND METHODS: A prospective cohort study was performed to compare V-Loc (n = 40) with polyglactin (n = 40) sutures. Division of the dorsal venous complex and formation of the UVA during robot-assisted radical prostatectomy using V-Loc or polyglactin sutures were studied. Preoperative, intraoperative, and postoperative parameters were measured. RESULTS: V-Loc sutures were associated with a statistically significant reduction in mean dorsal vein suture time (3.15 minutes V-Loc vs 3.75 minutes IS, P = .02) and UVA anastomosis time (8.5 minutes V-Loc vs 11.5 minutes IS, P = .001). No significant difference was noted between operative time (121 minutes V-Loc vs 130 minutes IS, P = .199), delayed healing rates (5% V-Loc vs 7.5% IS, P = .238), continence rate at 12 months (97.5% V-Loc vs 95% IS, P = .368), and urethral stenosis rates (2.5% V-Loc vs 2.5% IS, P = .347) in both groups. CONCLUSION: The use of a V-Loc running suture with a single needle driver is a feasible, reproducible, and economic technique with no significant difference in continence rates and urethral stenosis rates, compared with the use of a traditional interrupted suture.

RESUMO

BACKGROUND: Patients with end-stage renal disease (ESRD) are at risk of developing renal tumours. OBJECTIVE: Compare clinical, pathologic, and outcome features of renal cell carcinomas (RCCs) in ESRD patients and in patients from the general population. DESIGN, SETTING, AND PARTICIPANTS: Twenty-four French university departments of urology participated in this retrospective study. INTERVENTION: All patients were treated according to current European Association of Urology guidelines. MEASUREMENTS: Age, sex, symptoms, tumour staging and grading, histologic subtype, and outcome were recorded in a unique database. Categoric and continuous variables were compared by using chi-square and student statistical analyses. Cancer-specific survival (CSS) was assessed by Kaplan-Meier and Cox methods. RESULTS AND LIMITATIONS: The study included 1250 RCC patients: 303 with ESRD and 947 from the general population. In the ESRD patients, age at diagnosis was younger (55 ± 12 yr vs 62 ± 12 yr); mean tumour size was smaller (3.7 ± 2.6 cm vs 7.3 ± 3.8 cm); asymptomatic (87% vs 44%), low-grade (68% vs 42%), and papillary tumours were more frequent (37% vs 7%); and poor performance status (PS; 24% vs 37%) and advanced T categories (≥ 3) were more rare (10% vs 42%). Consistently, nodal invasion (3% vs 12%) and distant metastases (2% vs 15%) occurred less frequently in ESRD patients. After a median follow-up of 33 mo (range: 1-299 mo), 13 ESRD patients (4.3%), and 261 general population patients (27.6%) had died from cancer. In univariate analysis, histologic subtype, symptoms at diagnosis, poor PS, advanced TNM stage, high Fuhrman grade, large tumour size, and non-ESRD diagnosis context were adverse predictors for survival. However, only PS, TNM stage, and Fuhrman grade remained independent CSS predictors in multivariate analysis. The limitation of this study is related to the retrospective design. CONCLUSIONS: RCC arising in native kidneys of ESRD patients seems to exhibit many favourable clinical, pathologic, and outcome features compared with those diagnosed in patients from the general population.
