A multiparametric magnetic resonance imaging-based virtual reality surgical navigation tool for robotic-assisted radical prostatectomy
2019
Objective Increased computational power and improved visualization hardware have generated more opportunities for virtual reality (VR) applications in healthcare. In this study, we test the feasibility of a VR-assisted surgical navigation system for robotic-assisted radical prostatectomy. Material and methods The prostate, all magnetic resonance imaging (MRI) visible tumors, and important anatomic structures like the neurovascular bundles, seminal vesicles, bladder, and rectum were contoured on a multiparametric MRI using an in-house segmentation software. Three-dimensional (3-D) VR models were rendered and evaluated in a side room of the operating room. While interacting with the VR platfo…
Resección extendida y exenteración pélvica en el cáncer de recto del tercio inferior
2014
Approximately 10% of all low rectal cancer needs surgical resection extended to other pelvic structures. Indication for extended resection should be given according to a precise systemic and local preoperative staging. Magnetic Resonance Imaging is the most important instrument utilized by the Multidisciplinary Team to decide therapeutic strategy according to the surgical risk. The status of the pathological circumferential resection margin is the most important prognostic factor determining local recurrence risk and oncological outcome and for this reason it should be considered pivotal in the decision of the strategy of treatment. When extended resection is performed, the presence of an e…
Robot-Assisted Transvesical Enucleation of Benign Prostatic Hyperplasia: Lessons from a Single Surgeon’s Learning Curve
2014
Abstract Introduction Open simple prostatectomy is a well-established and effective operation for prostate volumes greater than 80 gm but also associated with bleeding and urinary incontinence. To benefit from the advances of laparoscopy, robot-assisted simple prostatectomy was established. We determined the learning curve of this minimally invasive surgery by evaluating the first procedures by an experienced robotic surgeon. Methods Patients presenting for surgical therapy with prostate volumes greater than 80 gm were considered for the study. Evaluation included validated questionnaires preoperatively, and at 6 and 12 weeks postoperatively. Blood loss, transfusions, operation time and pad…
The percentage of free prostate-specific antigen does not predict extracapsular disease in patients with clinically localized prostate cancer before …
2001
Objective To determine whether the percentage of free/total prostate-specific antigen (f/tPSA) can predict the pathological features in patients with clinically localized prostate cancer before radical prostatectomy. Patients and methods Univariate and multivariate logistic regression was used to analyse data from 171 untreated patients who underwent radical prostatectomy. Variables included the total PSA (tPSA), fPSA, f/tPSA, biopsy Gleason score, clinical stage and patient age. Results In 115 patients with pathologically organ-confined tumours ( pT2N0) the mean (sd) tPSA value was 6.9 (5.6) ng/mL; in 56 patients with extracapsular disease ( pT3pN0/N+) it was 10.2 (7.6) ng/mL; the respecti…
Wpływ stanu napięcia mięśni dna miednicy na ocenę poziomu zaburzeń erekcji i nietrzymania moczu u osób po prostatektomii radykalnej. Doniesienie wstę…
2017
Celem pracy była ocena, jak napięcie mięśni dna miednicy (MDM) mierzonego za pomocą sEMG wpływa na ocenę obiektywną i subiektywną trzymania moczu oraz zaburzeń erekcji. W badaniach uczestniczyło 10 mężczyzn, będących po zabiegu prostatektomii. Nasilenie objawów nietrzymania moczu oceniano na podstawie kwestionariusza ICIQ-SF, aktywność seksualną kwestionariuszem IIEF-5. Nie wykazano istotnego statystycznie związku między napięciem MDM, ocenianego za pomocą sEMG, a obiektywnymi wyznacznikami nietrzymania moczu, jednakże zaobserwowano tendencję, że niższe napięcie MDM występuje częściej u chorych ze wszystkimi dolegliwościami w ocenie subiektywnej.
