Transvaginal ultrasonography for trigonitis diagnosis in women.

Objective: Chronic trigonitis (CT) is usually diagnosed through cystoscopy which is invasive and expensive. Thus, an accurate non-invasive diagnostic method is necessary. The objective of this study is to determine the efficacy of transvaginal bladder ultrasound (TBU) for CT diagnosis.

Long-term efficacy of complete trigonal electrofulguration for women with recurrent urinary tract infections.

Introduction And Objective: Recurrent urinary tract infections (R-UTIs) have a negative impact on quality of life and contribute to antimicrobial resistance. Long-term antibiotic therapy is the main treatment alternative but, in some cases, this approach may not be accepted by the patient, is ineffective or poorly tolerated. In selected women, electrofulguration (EF) of trigonal lesions has been shown to reduce urinary tract infection (UTI) episodes.

INFLUENCE OF MINIMALLY INVASIVE LAPAROSCOPIC EXPERIENCE SKILLS ON ROBOTIC SURGERY DEXTERITY.

Background: It is unclear if there is a natural transition from laparoscopic to robotic surgery with transfer of abilities.

Aim: To measure the performance and learning of basic robotic tasks in a simulator of individuals with different surgical background.

Videolaparoscopic prostatectomy in porcine model for training residents.

Introduction:: Surgical training models prepare the resident for a more ethical surgical practice as well as providing a less steep learning curve. In urology, there are well-known models of pyeloplasty simulation, urethro-vesical anastomosis and nephrectomy, which have helped in the training of urology residents (–3). Learning laparoscopic prostatectomy is a difficult surgery and requires advanced surgical skill from the surgeon (4), requires operate without a direct view of the surgical field in a two-dimensional space and with longer instruments (5).

Objectives: To systematically summarize the available evidence concerning the impact of pyeloplasty on symptoms and differential renal function (DRF) in adults with unilateral UPJO in poorly functioning kidneys (PFK), and to identify potential predictors of kidney function recovery that could help clinicians select candidates for pyeloplasty.

Methods: A literature search (MEDLINE, Embase, Google Scholar, Scopus, ClinicalTrials.gov, and the WHO Clinical Trials Registry) and systematic review were performed up to September 2020 according to the PRISMA guidelines.

Recommendations on robotic-assisted radical prostatectomy: a Brazilian experts' consensus.

Radical prostatectomy is a commonly adopted treatment for localized/locally advanced prostate cancer in men with a life expectancy of ten years or more. Robotic-assisted radical prostatectomy (RARP) is comparable to open radical prostatectomy on cancer control and complication rates; however, new evidence suggests that RARP may have better functional outcomes, especially with respect to urinary incontinence and erectile dysfunction. Some of the surgical steps of RARP are not adequately described in published literature and, as such, may have an impact on the final outcomes of the procedure.

Extended Versus Limited Pelvic Lymph Node Dissection During Radical Prostatectomy for Intermediate- and High-risk Prostate Cancer: Early Oncological Outcomes from a Randomized Phase 3 Trial.

Background: The role of extended pelvic lymph node dissection (EPLND) in the surgical management of prostate cancer (PCa) patients remains controversial, mainly because of a lack of randomized controlled trials (RCTs).

Objective: To determine whether EPLND has better oncological outcomes than limited PLND (LPLND.

Design, Setting And Participants: This was a prospective, single-center phase 3 trial in patients with intermediate- or high-risk clinically localized PCa.

Laparoscopic pyeloplasty as an alternative to nephrectomy in adults with poorly functioning kidneys due to ureteropelvic junction obstruction.

Objectives: To evaluate outcomes of laparoscopic pyeloplasty (LP) in adults with poorly functioning kidney due to ureteropelvic junction obstruction (UPJO).

Methods: A retrospective comparative analysis was performed between adult patients who underwent LP due to UPJO with differential renal function (DRF) ≤ 15% and DRF > 15%. LP success rate and complications were assessed.

Retroperitoneoscopic ureterolithotomy to treat large ureteral stones in the proximal ureter.

Introduction: Retroperitoneoscopic ureterolithotomy emerged as an option for the extraction of large stones in the proximal ureter, offering short convalescence and low rates of residual fragments.

To analyze the preoperative variables associated to the postoperative glomerular filtration rate (GFR) outcomes after nephrectomy for benign and malignant conditions, measured by the reference isotopic technique Cr- (Cr-EDTA) and to create a model to predict the short-term postoperative GFR. Secondary aim was to evaluate which of the common equations for GFR estimation (Cockcroft-Gault, Modification of Diet in Renal Disease [MDRD] or Chronic Kidney Disease Epidemiology Collaboration [CKD-EPI]) has the best correlation with the Cr-EDTA. Patients undergoing unilateral nephrectomy from 2014 to 2018 were selected.

Postgraduate course in minimally invasive urological surgery.

Background: Minimally invasive surgeries are increasingly common as the first option for most urological diseases. However, laparoscopic techniques are difficult to master, especially for surgeons who were not trained during their residency programs. Therefore, postgraduate courses are important for such matters.

Periprostatic innervation: New issues based on segmental analysis of 10 human cadaver pelvic blocs.

Background: The exact paths of periprostatic nerves have been under debate over the last decades. In the present study, the topographic distribution of nerves around the prostate and their relative distances from the prostatic capsule were analyzed in male cadaver visceral blocs.

Methods: The pelvic organs from ten fresh male cadavers were removed and serial sectioned en bloc for histological investigation.

Step-by-step Laparoscopic Vesiculectomy for Hemospermia.

Unlabelled: Hemospermia has been considered as a benign and self-limiting condition. It usually has an inflammatory or infectious cause. However, recurrent or persistent hemospermia may indicate a more serious underlying pathology, especially over 40 years of age.

Robotic-assisted radical prostatectomy learning curve for experienced laparoscopic surgeons: does it really exist?

Background: Robotic-assisted radical prostatectomy (RALP) is a minimally invasive procedure that could have a reduced learning curve for unfamiliar laparoscopic surgeon. However, there are no consensuses regarding the impact of previous laparoscopic experience on the learning curve of RALP. We report on a functional and perioperative outcome comparison between our initial 60 cases of RALP and last 60 cases of laparoscopic radical prostatectomy (LRP), performed by three experienced laparoscopic surgeons with a 200+LRP cases experience.
