Objective: The objective of this work is to present initial perioperative, immediate continence and oncological results in a series of 25 prostate cancer patients treated with Retzius-sparing robot-assisted radical prostatectomy., Material and Methods: We retrospectively analyzed a series of 25 patients treated with Retzius-sparing robot-assisted radical prostatectomy for cT1-T2b prostate cancer between 2018-2019. The 5 stages of surgery are described. We make a descriptive statistic of our initial series and its outcomes in terms of immediate continence, defined as the use of 0 pad/diapers or 1 safety pad/diaper every 24 hours, one week after catheter removal., Results: Median follow-up, 6 months (3-18). Median PSA, 6.1 ng/ml (4-14.3). All surgeries were performed through a posterior intrafascial approach, and bilateral nerve-sparing was carried out in 84% of the cases. Affected surgical margins were present in 28%, being the apex the most frequent site of affectation. Surgical complications: 1 (4%) patient required transfusion of blood products in the immediate postoperative period. Mean hospital stay was 48 hours. Functional outcomes: 80% of the patients present immediate continence. 80% of continent patients do not require the use of any safety pads/diapers. Oncological outcomes: 84% are free of biochemical-progression in a median follow-up of 6 months., Conclusions: Initial functional results in terms of immediate continence are very satisfactory in patients who have undergone Retzius-sparing robot-assisted radical prostatectomy without negative impact on prognosis., (Copyright © 2020 AEU.

Purpose: To evaluate the role and success rate of urethral reconstruction in patients with urethral stricture previously treated with thermos-expandable Memokath™ urethral endoprosthesis., Materials and Method: A case series of patients with urethral stricture and Memokath™ endoprosthesis treated with urethroplasty is presented. Reconstruction was decided due to stricture progression or complications derived from primary stent treatment. Age, stricture and stent length, time between stent placement and urethroplasty, mode of stent retrieval, type of urethroplasty, complications and voiding parameters before and after urethroplasty were evaluated. Successful outcome was defined as standard voiding, without need of any postoperative procedure., Results: Eight cases with bulbar urethra stricture were included. Memokath™ was endoscopically retrieved before urethroplasty in 6 (75%) and by open urethrotomy at the time of urethroplasty in 2 (25%). Technique of urethroplasty was dorso-lateral onlay buccal mucosa graft in 5 (62.5%) cases and excision and primary anastomosis, anastomotic urethroplasty, and dorsal onlay buccal mucosa graft in one (12.5%) case each. There was no failure at 26±21.5 months median follow-up. Total IPSS, QoL, Qmax and postvoid residual significantly improved (P<.05). The only complication presented was epididymitis and penile shortening in one patient (12.5%)., Conclusions: Urethroplasty after re-stricture or other complications in patients with temporary Memokath™ urethral stent is a viable and definite option of reconstruction with excellent results in the short term and few complications. One-side dorsolateral onlay buccal mucosa graft augmentation is the optimal technique for this indication., (Copyright © 2018 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.)

Introduction: Stress urinary incontinence (SUI) is a significant sequela of prostate cancer surgery. In this article, we present the surgical technique and safety and efficacy of the adjustable transobturator male system (ATOMS®) with preattached scrotal port., Material and Method: An open prospective study was conducted at a university hospital with the main objective of changing the baseline condition after adjustment in the daily pad count and their wet weight (pad test). The secondary objectives were the quality-of-life assessment (International Consultation on Incontinence Questionnaire-Short Form [ICIQ-SF] and Incontinence Impact Questionnaire-7 [IIQ-7], baseline and after the adjustment), patient-perceived results (Patient Global Index [PGI] and Global Response Assessment [GRA] at 1 year) and assessment of complications according to Clavien-Dindo. The numerical values are expressed in median ± IQR., Results: We analysed 60 consecutive patients with a follow-up of 21±22 months. The baseline pad-test was 465±450mL, and the pad-count was 5+3 pads/day. The baseline SUI was mild (11.6% of patients), moderate (25%) and severe (63.3%). The operative time was 60±25min, the hospital stay was 1±0 days, and the visual analogue scale of pain on day 1 after surgery was 0±1. The total filling was 16.5±7mL, and the number of refillings was 1±2. The pad-test and pad-count after the adjustment were 0±20mL and 0±1, respectively (both p<.0001 compared with baseline). SUI disappeared (81.7%) or remained mild (11.7%), moderate (5%) or severe (1.6%). We observed a reduction in the ICIQ-SF (p<.0001) and IIQ-7 scores (p=.0003). Both continence (p=.002) and satisfaction (p=.03) were lower in the irradiated patients. Complications occurred in 11 cases (18.6%), 8 (13.5%) of which were grade I and 3 (5.1%) of which were grade 3. The treatment satisfaction rate was 91.7%, and the patient-perceived overall improvement at 1 year was highly pronounced (PGI-I score, 1±1; GRA, 6±1)., Conclusions: SUI treatment of men using third-generation ATOMS® is safe and effective in the short-term, even in patients with severe SUI. The rate of dry patients after the adjustment exceeded 80%, and the satisfaction rates exceeded 90%. The patients assessed this treatment highly positively., (Copyright © 2018 AEU.

Objectives: To compare the different endovesical therapeutic regimes in terms of clinical effectiveness based on glycosaminoglycan replenishment agents (RA-GAG) available on the market in Spain., Material and Methods: A bibliographic analysis was made of the studies published in Medline from 1996 to 2012 on RA-GAG of application in the bladder, placing emphasis on the clinical results. A post-hoc comparison was made of the efficacy of this treatment in the studies conducted in patients with interstitial cystitis in different conditions by calculating the effect sizes to analyze improvement on the pain visual analogue scale (VAS) and clinical response rate. The number of patients needed to treat (NNT) for the different agents was calculated based on the odds ratio and associated economic implications., Results: The globally available evidence is scarce. There are 38 articles about RA-GAGs in different indications, 71 of them in interstitial cystitis and only 8 may assist in establishing a comparison between the results presented. The treatments used were placebo, 0.8% high molecular weight hyaluronic acid (Cystistat(®)), 2% chondroitin sulfate sodium (Uracyst(®)) and a combination of 1.6% low molecular weight hyaluronic acid plus 2% chondroitin sulfate (Ialuril(®)), between 6 and 12 instillations. Another low molecular weight hyaluronic acid preparation (Uromac(®)) lacks any scientific evidence. All the therapeutic elements studied show a mean score decrease on the pain VAS and increase in the rate of post-treatment response. The NNT for the treatments that are statistically more beneficial over placebo ranges from 1.6 and 4.1. The post-hoc comparison of the response rates has established that Cystistat(®) 12 instillations (OR 18.8; 95% CI 6.4-57.2; P=.001) or 10 instillations (OR 19.2; 95% CI 5.3-75.3; P=.001) are the treatment regimes that obtain maximum effectiveness. In both cases, the NNT was 1.6., Conclusions: This study has multiple limitations inherent to the nature of the design. However, although the available literature is scarce, it shows that there are differences regarding the clinical effectiveness of the different agents and regimes used for endovesical treatment of interstitial cystitis. These differences also entail economic type implications., (Copyright © 2012 AEU. Published by Elsevier España. All rights reserved.)

Context: Radical cystectomy with orthotopic derivation is one of the most complex urological techniques, although laparoscopic surgery has made this procedure increasingly less invasive., Objective: To provide an up-dated review of the single port approach to carry out radical surgery due to bladder cancer., Evidence Acquisition: A comprehensive review of the literature was performed using Medline and Embase to discover the accumulated experience of the viability of carrying out laparoendoscopic radical cystectomy, pelvic lymphadenectomy and orthotopic neobladder using the laparoendoscopic single site surgery (LESS) approach. Our experience with this approach is also presented and the technique used with the reusable KeyPort(®) system developed by Richard Wolf is described., Evidence Synthesis: Radical treatment of bladder cancer is possible in men and women using a single port and even performance of ileal neobladder, as reconstructive procedure in these patients. The surgical technique, post-operative cares and result obtained in our center are described. The accumulated experience worldwide describes 25 cases of radical cystectomy performed using different single port systems, 14 of them with orthotopic intestinal neobladder., Conclusion: The KeyPort(®) umbilical cystectomy constitutes in our setting the least possible invasive alternative to efficiently treat muscle-invasive bladder cancer, with excellent esthetic result, minimum post-operative pain and short hospital stay. The umbilical scar decreases the analgesic requirements and it ends up being practically invisible. This supposes an important step in the development of the minimally invasive surgery for bladder cancer., (Copyright © 2012 AEU. Published by Elsevier Espana. All rights reserved.)

Objectives: Treatment of feminine stress urinary incontinence (SUI) with slings aims to supplement the function of the damaged ligaments, favoring the correct transmission of the tensions. Our objective is to determine which preoperative variables could predict the outcome of surgical treatment of SUI and to study the urodynamic changes produced by the surgery., Material and Methods: 139 women (age X =61.7; σ=10.88) operated on due to SUI were studied retrospectively. In 118 cases (84.8%), sling techniques (TVT, TOT, TVT-Safyre, REEMEX) were used. Clinical evaluation and complete preoperative video -urodynamics were made pre-operatively and at 3 months of surgery. A statistical study (Fisher's test, Wilcoxon, Friedman, Student's T and Pearson's χ(2)) and analysis of multivariant logistic regression analysis by step elimination method were performed., Results: Post-operatively, the SUI (p=0.000) and bladder hyperactivity syndrome decreased. The success percentages (urodynamic absence of SUI) for each technique were: TVT-Safyre (75%), TOT (73%), TVT (60%) and REEMEX (57%), without significant differences. Age (ROC cut-off: 61 years) was a prognostic factor of success (p=0.024). Preoperative maximum flow (Qmax) (16 ml/s) constituted the only urodynamic parameter with a predictive value for success (p=0.026). An open bladder neck was a risk factor for persistence of postoperative SUI (RR=2.78). A significant decrease of the postsurgical Qmax (p=0.017) was verified, without increase of the post micturation residue or of the Wmax. An increase of the postsurgical urethral resistance (UR) was also observed (p=0.004)., Conclusions: The pre-operative Qmax is the most important urodynamic prognostic parameter in feminine SUI surgery, its normality being associated to a greater probability of cure of the incontinence. In the cases of decreased preoperative flow, use of slings that increase urethral resistance more (REEMEX) is not recommended. Hyperactivity of the preoperative detrusor does not significantly modify the results of surgery of the SUI., (Copyright © 2010 AEU. Published by Elsevier Espana. All rights reserved.)
